SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	ACCOUNTING PRINCIPLES The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. The following is a description of Honeywell’s significant accounting policies. PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements include the accounts of Honeywell International Inc. and all of its subsidiaries and entities in which a controlling interest is maintained. The Company's consolidation policy requires equity investments that the Company exercises significant influence over but do not control the investee and are not the primary beneficiary of the investee’s activities to be accounted for using the equity method. Investments through which the Company is not able to exercise significant influence over the investee and which the Company does not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation. RECLASSIFICATIONS Certain prior year amounts have been reclassified to conform to the current year presentation. RECENT ACCOUNTING PRONOUNCEMENTS The Company considers the applicability and impact of all Accounting Standards Updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's consolidated statement of operations, balance sheet and cash flows (Consolidated Financial Statements). In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The standard’s amendments include changes in various subtopics of accounting for income taxes including, but not limited to, accounting for “hybrid” tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, intraperiod tax allocation exception to incremental approach, ownership changes in investments, interim-period accounting for enacted changes in tax law, and year-to-date loss limitation in interim-period tax accounting. Effective January 1, 2021, the Company adopted this standard. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounted principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope , to expand the scope of this guidance to include derivatives. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company will apply the guidance to impacted transactions during the transition period. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. This ASU should be applied prospectively to acquisitions occurring on or after the effective date of December 15, 2022, and early adoption is permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements. RESEARCH AND DEVELOPMENT Research and development costs for projects are expensed as incurred, unless these costs relate to contracts with customers where the Company receives reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Cost of products and services sold and were $1,333 million, $1,334 million and $1,556 million for the years ended December 31, 2021, 2020 and 2019, respectively. Costs related to contracts with customers for customer-sponsored research and development projects are included as a contract cost and included in Cost of products and services sold when revenue from such contracts is recognized, consistent with the Company's sales recognition policies. This revenue was $1,284 million, $1,200 million and $1,079 million for the years ended December 31, 2021, 2020 and 2019, respectively. CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less. INVENTORIES Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. Carrying value adjustments for inventory obsolescence is equal to the difference between the cost and net realizable value. Net realizable value is the estimate selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost, including any asset retirement obligations, less accumulated depreciation. For financial reporting, the straight-line method of depreciation is used over the estimated useful lives of 10 to 50 years for buildings and improvements an d 3 to 16 years for machinery and equipment. Recognition of the fair value of obligations associated with the retirement of tangible long-lived assets is required when there is a legal obligation to incur such costs. Upon initial recognition of a liability, the cost is capitalized as part of the related long-lived asset and depreciated over the corresponding asset’s useful life. GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETS Goodwill and indefinite-lived intangible assets are subject to impairment testing annually as of March 31, or if a triggering event occurs or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. The Company completed its annual goodwill impairment test as of March 31, 2021, and determined that there was no impairment as of that date. The Company is not aware of any additional triggering events. FINITE-LIVED INTANGIBLE ASSETS Other intangible assets with determinable lives consist of customer lists, technology, patents and trademarks and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 22 years. FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income (loss). For subsidiaries operating in highly inflationary environments, inventories and property, plant and equipment, including related expenses, are remeasured at the exchange rate in effect on the date the assets were acquired, while monetary assets and liabilities are remeasured at year-end exchange rates. Remeasurement adjustments for these subsidiaries are included in earnings. DERIVATIVE FINANCIAL INSTRUMENTS All derivative financial instruments are recorded on the balance sheet as assets or liabilities and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the changes in fair value of the derivatives are recorded in Accumulated other comprehensive income (loss) and subsequently recognized in earnings when the hedged items impact earnings. Derivative financial instruments designated as hedges must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged item. The Company elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and recognize the initial value of the excluded component in earnings using the amortization approach. For derivative instruments that are designated and qualify as a net investment hedge, the gain or loss is reported as a component of Other comprehensive income (loss) and recorded in Accumulated other comprehensive income (loss). The gain or loss will be subsequently reclassified into net earnings when the hedged net investment is either sold or substantially liquidated. LEASES At the inception of a contract, the Company assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. All significant lease arrangements are generally recognized at lease commencement. Operating lease right-of-use (ROU) assets and lease liabilities are recognized at commencement. An ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases), and we recognize lease expense for these leases as incurred over the lease term. ROU assets represent the Company's right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses its incremental borrowing rate, which is based on the information available at the lease commencement date, in determining the present value of the lease payments. In determining the borrowing rate, the Company considers the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than U.S. dollar, the collateralized borrowing rate in the foreign currency using the U.S. dollar and foreign currency swap spread, when available. PENSION BENEFITS The Company presents net periodic pensions costs by disaggregating the service cost component of such costs and reports those costs in the same line item or items in the Consolidated Statement of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of such costs are required to be presented separately from the service cost component. The Company records the service cost component of Pension ongoing (income) expense in Costs of products and services sold and Selling, general and administrative expenses. The remaining components of costs within Pension ongoing (income) expense, primarily interest costs and assumed return on plan assets, are recorded in Other (income) expense. The Company recognizes net actuarial gains or losses in excess of 10% of the greater of the fair value of plan assets or the plan's projected benefit obligation (the corridor) annually in the fourth quarter each year (MTM Adjustment). The MTM Adjustment is also reported in Other (income) expense. See Note 22 Segment Financial Data for a definition of Pension ongoing (income) expense. SALES RECOGNITION Product and service sales are recognized when or as the Company transfers control of the promised products or services to its customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Service sales, principally representing repair, maintenance and engineering activities, are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as the Company performs on these contracts because of the continuous transfer of control to the customer. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for contracts because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost input method, the extent of progress towards completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on significant contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required. The customer funding for costs incurred for nonrecurring engineering and development activities of the Company's products under agreements with commercial customers is deferred and subsequently recognized as revenue as products are delivered to the customers. Additionally, expenses incurred, up to the customer agreed funded amount, are deferred as an asset and recognized as cost of sales when products are delivered to the customer. The deferred customer funding and costs result in recognition of deferred costs (asset) and deferred revenue (liability) on the Company's Consolidated Balance Sheet. Capitalized contract fulfillment costs were approximately $1.3 billion as of December 31, 2021 and 2020. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the years ended December 31, 2021, 2020 and 2019. Revenues for the Company's mechanical service programs are recognized as performance obligations that are satisfied over time, with recognition reflecting a series of distinct services using the output method. The terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, cash-based incentives, rebates, performance awards, or credits. The Company estimates variable consideration at the most likely amount the Company will receive from customers. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. The Company's estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company. STOCK-BASED COMPENSATION PLANS The principal awards issued under the Company's stock-based compensation plans, which are described in Note 15 Stock-Based Compensation Plans, are non-qualified stock options and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods (generally the vesting period of the equity award) and is included in Selling, general and administrative expenses. Forfeitures are estimated at the time of grant to recognize expense for those awards that are expected to vest and are based on the Company's historical forfeiture rates. INCOME TAXES Significant judgment is required in evaluating tax positions. The Company establishes reserves for income taxes when, despite the belief that tax positions are fully supportable, there remain certain positions that do not meet the minimum recognition threshold. The approach for evaluating certain and uncertain tax positions is defined by the authoritative guidance which determines when a tax position is more likely than not to be sustained upon examination by the applicable taxing authority. In the normal course of business, the Company and its subsidiaries are examined by various federal, state and foreign tax authorities. The Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of the Company's provision for income taxes. The Company continually assesses the likelihood and amount of potential adjustments and adjust the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a change in estimate become known. For additional information, see Note 5 Income Taxes. EARNINGS PER SHARE Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding. ENVIRONMENTAL The Company accrues costs related to environmental matters when it is probable that it has incurred a liability related to a contaminated site and the amount can be reasonably estimated. For additional information, see Note 19 Commitments and Contingencies. ASBESTOS RELATED LIABILITIES AND INSURANCE RECOVERIES The Company recognizes a liability for any asbestos related contingency that is probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos related matters, the Company records asbestos related insurance recoveries that are deemed probable. For additional information, see Note 19 Commitments and Contingencies. REIMBURSEMENT RECEIVABLES In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into a reimbursement agreement under which Honeywell receives cash payments as reimbursement primarily related to net spending for environmental matters at certain sites as defined in the reimbursement agreement. Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell environmental spend, and the Company monitors the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS AND DIVESTITURES ACQUISITIONS On November 29, 2021, Honeywell Quantum Solutions, a wholly-owned subsidiary of Honeywell, and Cambridge Quantum Computing, a leading developer of quantum computing and quantum software, combined to form Quantinuum. Prior to closing the transaction, Honeywell held a 4.2% ownership interest in Cambridge Quantum Computing. At closing of the business combination, Honeywell contributed an additional $270 million of cash and is the controlling majority-owner of Quantinuum, with an overall 54% ownership in the business. Quantinuum is well positioned to lead the quantum computing industry by offering advanced, fully integrated hardware and software solutions at an unprecedented pace, scale and level of performance to large high-growth markets worldwide. Quantinuum supports customer needs for improved computation in cyber security, drug discovery and delivery, material science, finance, and optimization across all major industrial markets. The business is included within Corporate and All Other, which is not considered a reportable business segment. The combination was accounted for under the acquisition method of accounting; as such, assets and liabilities of Quantinuum are consolidated by Honeywell and included in the Consolidated Balance Sheet. Upon close of the transaction, Honeywell recorded a non-cash adjustment of $460 million in Additional paid-in-capital on the Consolidated Balance Sheet as the contribution of ownership interest in Honeywell Quantum Solutions and Cambridge Quantum Computing for the formation of Quantinuum. In addition, Honeywell recognized a gain of $22 million related to the fair value remeasurement of Honeywell's existing 4.2% ownership interest in Cambridge Quantum Computing, which was recorded in Other (income) expense on in the Consolidated Statement of Operations. At close of the transaction, the fair value of Cambridge Quantum Computing's noncontrolling interest in Quantinuum was $419 million. In December 2021, Cambridge Quantum Computing contributed cash of $12 million to Quantinuum, increasing their noncontrolling interest and decreasing Honeywell's additional-paid-in-capital. As of December 31, 2021, the assets and liabilities in Honeywell's Consolidated Balance Sheet includes $90 million of intangible assets and $943 million allocated to goodwill, which is non-deductible for tax purposes.

For a summary by disaggregated product and services sales for each segment, refer to Note 22 Segment Financial Data. The Company recognizes revenue arising from performance obligations outlined in contracts with its customers that are satisfied at a point in time and over time. The disaggregation of the Company's revenue based off timing of recognition is as follows: Years Ended December 31, 2021 2020 2019 Products, transferred point in time 58 % 61 % 61 % Products, transferred over time 17 15 14 Net product sales 75 76 75 Services, transferred point in time 8 8 9 Services, transferred over time 17 16 16 Net service sales 25 24 25 Net sales 100 % 100 % 100 % CONTRACT BALANCES The Company records progress on satisfying performance obligations under contracts with customers and the related billings and cash collections are recorded on the Consolidated Balance Sheet in Accounts receivable—net and Other assets (unbilled receivables (contract assets) and billed receivables) and Accrued liabilities and Other liabilities (customer advances and deposits (contract liabilities)). Unbilled receivables (contract assets) arise when the timing of cash collected from customers differs from the timing of revenue recognition, such as when contract provisions require specific milestones to be met before a customer can be billed. Contract assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Contract liabilities are recorded when customers remit contractual cash payments in advance of us satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities are derecognized when revenue is recorded, either when a milestone is met triggering the contractual right to bill or when the performance obligation is satisfied. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company's contract assets and liabilities balances: 2021 2020 Contract assets—January 1 $ 1,618 $ 1,602 Contract assets—December 31 2,060 1,618 Change in contract assets—increase (decrease) $ 442 $ 16 Contract liabilities—January 1 $ (4,033) $ (3,501) Contract liabilities—December 31 (4,290) (4,033) Change in contract liabilities—(increase) decrease $ (257) $ (532) Net change $ 185 $ (516) The net change in 2021 and 2020 was primarily driven by the receipt of advance payments from customers exceeding recognition of revenue as performance obligations were satisfied prior to billing. For the years ended December 31, 2021 and 2020, the Company recognized revenue of $1,925 million and $1,709 million, respectively, that was previously included in the beginning balance of contract liabilities. Contract assets include $2,035 million and $1,589 million of unbilled balances under long-term contracts as of December 31, 2021 and 2020, respectively. These amounts are billed in accordance with the terms of customer contracts to which they relate. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications for goods or services and not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively. PERFORMANCE OBLIGATIONS A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. When the Company's contracts with customers require highly complex integration or manufacturing services that are not separately identifiable from other promises in the contracts and, therefore, not distinct, then the entire contract is accounted for as a single performance obligation. In situations when the Company's contracts includes distinct goods or services that are substantially the same and have the same pattern of transfer to the customer over time, they are recognized as a series of distinct goods or services. For any contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative standalone selling price of each distinct good or service in the contract. For product sales, each product sold to a customer typically represents a distinct performance obligation. In such cases, the observable standalone sales are used to determine the stand alone selling price. Performance obligations are satisfied as of a point in time or over time. Performance obligations are supported by contracts with customers, providing a framework for the nature of the distinct goods, services or bundle of goods and services. The timing of satisfying the performance obligation is typically indicated by the terms of the contract. The following table outlines the Company's remaining performance obligations disaggregated by segment: December 31, 2021 Aerospace $ 9,423 Honeywell Building Technologies 6,871 Performance Materials and Technologies 7,243 Safety and Productivity Solutions 4,143 Corporate and All Other (1) 2 $ 27,682 (1) The remaining performance obligations within Corporate and All Other relate to the Quantinuum business. Performance obligations recognized as of December 31, 2021 will be satisfied over the course of future periods. The Company's disclosure of the timing for satisfying the performance obligation is based on the requirements of contracts with customers. However, from time to time, these contracts may be subject to modifications, impacting the timing of satisfying the performance obligations. Performance obligations expected to be satisfied within one year and greater than one year are 59% and 41%, respectively. The timing of satisfaction of the Company's performance obligations does not significantly vary from the typical timing of payment. Typical payment terms of the Company's fixed-price over time contracts include progress payments based on specified events or milestones, or based on project progress. For some contracts the Company may be entitled to receive an advance payment. The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount the Company has the right to invoice for services performed.

Restructuring and Related Activities [Abstract]
Repositioning and Other Charges	A summary of repositioning and other charges follows: Years Ended December 31, 2021 2020 2019 Severance $ 80 $ 475 $ 260 Asset impairments 117 21 95 Exit costs 134 69 83 Reserve adjustments (13) (47) (5) Total net repositioning charge 318 518 433 Asbestos related litigation charges, net of insurance and reimbursements 129 50 42 Probable and reasonably estimable environmental liabilities, net of reimbursements 22 27 59 Other charges 100 (20) 12 Total net repositioning and other charges $ 569 $ 575 $ 546 The following table summarizes the pre-tax distribution of total net repositioning and other charges by classification in the Consolidated Statement of Operations: Years Ended December 31, 2021 2020 2019 Cost of products and services sold $ 457 $ 308 $ 276 Selling, general and administrative expenses 112 267 270 Other (income) expense — — — $ 569 $ 575 $ 546 The following table summarizes the pre-tax amount of total net repositioning and other charges by segment. These amounts are excluded from segment profit as described in Note 22 Segment Financial Data. Years Ended December 31, 2021 2020 2019 Aerospace $ 62 $ 157 $ 33 Honeywell Building Technologies 13 100 108 Performance Materials and Technologies 24 167 93 Safety and Productivity Solutions 268 41 71 Corporate and All Other 202 110 241 $ 569 $ 575 $ 546 In 2021, the Company recognized repositioning charges totaling $331 million, including severance costs of $80 million related to workforce reductions of 6,432 manufacturing and administrative positions mainly in the Company's Safety and Productivity Solutions and Aerospace segments. The workforce reductions were primarily related to the re-alignment of a product line in the Company's Safety and Productivity Solutions segment, site transitions, mainly in Aerospace, to more cost-effective locations, and the Company's productivity and ongoing functional transformation initiatives. The repositioning charge included asset impairments of $117 million primarily related to the write-down of certain manufacturing and other equipment. The repositioning charge included exit costs of $134 million primarily for current period exit costs incurred for previously approved repositioning projects, closure obligations associated with site transitions, and lease obligations for equipment. Also, $13 million of previously established reserves, primarily for severance, were returned to income due to adjustments to the scope of previously announced repositioning actions. In 2021, Other charges include $105 million of incremental long-term contract labor cost inefficiencies due to severe supply chain disruptions (attributable to the COVID-19 pandemic) relating to the warehouse automation business within the Safety and Productivity Solutions segment. Certain of these costs incurred include amounts and provisions for anticipated losses recognized during the fourth quarter when total estimated costs at completion for certain of the business’ long-term contracts exceeded total estimated revenue. These costs represent unproductive labor costs due to unexpected supply delays and the resulting downstream installation issues, demobilization and remobilization of contract workers, and resolution of contractor disputes. These costs do not include normal operational inefficiencies experienced during a challenging operating environment in 2021. In 2020, the Company recognized repositioning charges totaling $565 million, including severance costs of $475 million related to workforce reductions of 14,159 manufacturing and administrative positions across the Company's segments, with a majority of the workforce reductions in Aerospace and Performance Materials and Technologies. The workforce reductions primarily related to the Company aligning its cost structure with the slowdown in demand for many of its products and services due to the global recession, the Company's productivity and ongoing functional transformation initiatives, and to site consolidations and hub strategies. The repositioning charge included exit costs of $69 million primarily related to current period exit costs incurred for previously approved repositioning projects. Also, $47 million of previously established reserves, primarily for severance, were returned to income mainly as a result of higher attrition than anticipated in prior severance actions resulting in lower payments. In 2019, the Company recognized repositioning charges totaling $438 million, including severance costs of $260 million related to workforce reductions of 5,336 manufacturing and administrative positions across the Company's segments. The workforce reductions related to the Company's productivity and ongoing functional transformation initiatives and to site transitions, mainly in Honeywell Building Technologies, as the Company transitions manufacturing to more cost-effective locations. The repositioning charge included asset impairments of $95 million largely related to a write down in connection with assets held for sale. The repositioning charge included exit costs of $83 million primarily related to current period exit costs incurred for previously approved repositioning projects, termination fees associated with the early cancellation of supply agreements for certain raw materials in Performance Materials and Technologies and Honeywell Building Technologies and for closure obligations associated with site transitions. The following table summarizes the status of the Company's total repositioning reserves: Severance Asset Exit Total Balance at December 31, 2018 $ 489 $ — $ 77 $ 566 Charges 260 95 83 438 Usage—cash (186) — (63) (249) Usage—noncash — (100) — (100) Divestitures — — — — Adjustments (8) 5 (2) (5) Foreign currency translation — — 1 1 Balance at December 31, 2019 555 — 96 651 Charges 475 21 69 565 Usage—cash (474) — (90) (564) Usage—noncash — (21) — (21) Divestitures — — — — Adjustments (44) — (3) (47) Foreign currency translation 15 — 2 17 Balance at December 31, 2020 527 — 74 601 Charges 80 117 134 331 Usage—cash (299) — (83) (382) Usage—noncash — (119) — (119) Divestitures — — — — Adjustments (14) 2 (1) (13) Foreign currency translation (5) — (2) (7) Balance at December 31, 2021 $ 289 $ — $ 122 $ 411

The increase was primarily due to the establishment of a valuation allowance for deferred tax assets not expected to be realized, incremental tax reserves, a lower tax benefit from restructuring and the absence of prior year items including tax benefits realized as a result of the favorable resolution of a foreign tax matter related to the spin-off transactions, tax law changes in India and the resolution of certain U.S. tax matters offset by a non-cash charge related to the reduction of the aggregate carrying value of certain receivables with no corresponding tax benefit. The Company’s non-U.S. effective tax rate was 26.0%, an increase of approximately 14.1 percentage points compared to 2020. The increase in the foreign effective tax rate was primarily attributable to incremental tax reserves, the tax impact of restructuring and the absence of prior year items including the favorable resolution of a foreign tax matter related to the previously completed spin-off transactions and tax law changes in India. The effective tax rate increased by 1.5 percentage points in 2020 compared to 2019. The increase was primarily attributable to accrued withholding taxes related to unremitted foreign earnings and non-cash charges related to the reduction of the aggregate carrying value of certain receivables with no corresponding tax benefit, offset by the favorable resolution of a foreign tax matter related to the previously completed spin-off transactions, tax impact of restructuring, tax law changes in India, and the resolution of certain U.S. tax matters. The Company’s non-U.S. effective tax rate was 11.9%, a decrease of approximately 14.2 percentage points compared to 2019. The decrease in the foreign effective tax rate was primarily attributable to the favorable resolution of a foreign tax matter related to the previously completed spin-off transactions, tax impact of restructuring, and tax law changes in India offset by accrued withholding taxes related to unremitted foreign earnings. DEFERRED TAX ASSETS (LIABILITIES) The tax effects of temporary differences and tax carryforwards which give rise to future income tax benefits and payables are as follows: Deferred tax assets: December 31, 2021 2020 Postretirement benefits other than pensions $ 77 $ 85 Asbestos and environmental 468 508 Employee compensation and benefits 174 180 Lease liabilities 242 197 Other accruals and reserves 260 110 Net operating and capital losses 734 779 Capital loss limitation and carryover 151 — Tax credit carryforwards 164 219 Gross deferred tax assets 2,270 2,078 Valuation allowance (857) (766) Total deferred tax assets $ 1,413 $ 1,312 Deferred tax liabilities: Pension $ (948) $ (548) Property, plant and equipment (464) (437) Right-of-use asset (230) (184) Intangibles (883) (898) Unremitted earnings of foreign subsidiaries (426) (398) Other asset basis differences (334) (169) Other (2) (31) Total deferred tax liabilities (3,287) (2,665) Net deferred tax liability $ (1,874) $ (1,353) The Company's gross deferred tax assets include $901 million related to non-U.S. operations comprised principally of net operating losses, capital loss and tax credit carryforwards, primarily in Canada, France, Germany, Luxembourg, and the United Kingdom, and deductible temporary differences. The Company maintains a valuation allowance of $703 million against a portion of the non-U.S. gross deferred tax assets. Additionally, a valuation allowance of $150 million was established against the U.S. gross deferred tax asset for capital losses generated from restructuring transactions during the year. The change in the valuation allowance resulted in an increase of $124 million, increase of $105 million, and a decrease of $23 million to income tax expense in 2021, 2020 and 2019, respectively. In the event the Company determines that it will not be able to realize its net deferred tax assets in the future, the Company will reduce such amounts through an increase to income tax expense in the period such determination is made. Conversely, if the Company determines that it will be able to realize net deferred tax assets in excess of the carrying amounts, the Company will decrease the recorded valuation allowance through a reduction to income tax expense in the period that such determination is made. As of December 31, 2021, the Company recorded a $426 million deferred tax liability on all unremitted foreign earnings based on estimated earnings and profits of approximately $17.1 billion as of the balance sheet date. As of December 31, 2021, the Company's net operating loss, capital loss and tax credit carryforwards were as follows: Jurisdiction Expiration Net Operating Tax Credit U.S. Federal 2040 $ 684 $ 97 U.S. State 2040 390 21 Non-U.S. 2041 466 50 Non-U.S. Indefinite 2,185 — $ 3,725 $ 168 Many jurisdictions impose limitations on the timing and utilization of net operating loss and tax credit carryforwards. In those instances, whereby there is an expected permanent limitation on the utilization of the net operating loss or tax credit carryforward, the deferred tax asset and amount of the carryforward have been reduced.

The following table summarizes tax years that remain subject to examination by major tax jurisdictions as of December 31, 2021: Jurisdiction Open Tax Years Based on Originally Filed Returns Examination in progress Examination not yet initiated U.S. Federal 2017-2018 2019-2021 U.S. State 2013-2019 2017-2021 Australia n/a 2018-2021 Canada (1) 2015-2018 2019-2021 China 2011-2020 2021 France 2018-2020 2021 Germany (1) 2009-2018 2019-2021 India 1999-2020 2021 Italy 2012-2018 2019-2021 Netherlands n/a 2018-2021 Switzerland (1) 2016-2018 2019-2021 United Kingdom 2013-2019 2020-2021 (1) Includes provincial or similar local jurisdictions, as applicable. Based on the outcome of these examinations, or as a result of the expiration of statute of limitations for specific jurisdictions, it is reasonably possible that certain unrecognized tax benefits for tax positions taken on previously filed tax returns will materially change from those recorded as liabilities in the Company's financial statements. In addition, the outcome of these examinations may impact the valuation of certain deferred tax assets (such as net operating losses) in future periods. Unrecognized tax benefits for examinations in progress were $592 million, $556 million, and $413 million, as of December 31, 2021, 2020 and 2019, respectively. Estimated interest and penalties related to the underpayment of income taxes are classified as a component of Tax expense in the Consolidated Statement of Operations and totaled $79 million, $80 million, and $73 million for the years ended December 31, 2021, 2020 and 2019, respectively. Accrued interest and penalties were $580 million, $507 million, and $487 million, as of December 31, 2021, 2020 and 2019, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	DERIVATIVES AND HEDGING ACTIVITIES The Company uses derivative financial instruments to manage its risks related to interest rates and foreign currency exchange rate fluctuations. Derivative financial instruments are not used for trading or other speculative purposes. To qualify as a hedge, derivative financial instruments must be evaluated for hedge effectiveness at the inception of the contract and designated as a hedge. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract. FOREIGN CURRENCY RISK MANAGEMENT The Company operates a global business in a wide variety of foreign currencies. The Company's exposure to market risk for changes in foreign currency exchange rates arises from international financing activities between subsidiaries, foreign currency denominated monetary assets and liabilities, and transactions arising from international trade. The Company's objective is to preserve the U.S. Dollar value of foreign currency denominated cash flows and earnings. The Company monitors its collective foreign currency exposure and enters into foreign currency exchange forward and option contracts (foreign currency exchange contracts) with third parties, when necessary, to minimize the impact of changes in foreign currency exchange rates. The Company has monetary assets and liabilities denominated in non-functional currencies. Prior to conversion into U.S. dollars, these assets and liabilities are remeasured at spot exchange rates in effect on the balance sheet date. The effects of changes in spot rates are recognized in earnings and included in Other (income) expense. The Company uses foreign currency exchange contracts to hedge its foreign currency exposure. These contracts are marked-to-market with the resulting gains and losses recognized in earnings offsetting the gains and losses on the non-functional currency denominated monetary assets and liabilities being hedged. The Company uses foreign currency contracts to hedge forecasted sales and purchases, which are denominated in non-functional currencies. Changes in the forecasted non-functional currency cash flows due to movements in exchange rates are substantially offset by changes in the fair value of these foreign currency exchange contracts designated as hedges. Market value gains and losses on these contracts are recognized in earnings when the hedged transaction is recognized. As of December 31, 2021, and 2020, the Company held contracts with notional amounts of $12,671 million and $16,123 million to exchange foreign currencies, principally the U.S. Dollar, Euro, Canadian Dollar, British Pound, Mexican Peso, Chinese Renminbi, and Indian Rupee. The Company also designates certain foreign currency debt and derivative contracts as hedges against portions of its net investment in foreign operations. Gains or losses of the foreign currency debt and derivative contracts designated as net investment hedges are recorded in the same manner as foreign currency translation adjustments. INTEREST RATE RISK MANAGEMENT Financial instruments, including derivatives, expose the Company to market risk related to changes in interest rates. The Company uses a combination of financial instruments, including long-term, medium-term, and short-term financing, variable-rate commercial paper, and interest rate swaps to convert the interest rate mix of the Company's total debt portfolio and related overall cost of borrowing. CREDIT RISK MANAGEMENT The Company continues to monitor the creditworthiness of its counterparties to mitigate the risk of nonperformance. Financial instruments, including derivatives, expose the Company to counterparty credit risk. In addition, the Company grants credit terms to its customers in the normal course of business. The terms and conditions of the Company's credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer. The Company's sales are not materially dependent on a single customer or a small group of customers. DERIVATIVE AND HEDGING INSTRUMENTS The following table summarizes the notional amounts and fair values of the Company’s outstanding derivatives by risk category and instrument type within the Consolidated Balance Sheet: Notional Fair Value Asset Fair Value (Liability) December 31, 2021 December 31, 2020 December 31, 2021 December 31, 2020 December 31, 2021 December 31, 2020 Derivatives in Fair Value Hedging Relationships: Interest rate swap agreements $ 3,150 $ 3,950 $ 60 $ 194 $ — $ — Derivatives in Cash Flow Hedging Relationships: Foreign currency exchange contracts 647 488 4 65 — (58) Derivatives in Net Investment Hedging Relationships: Foreign currency exchange contracts 746 806 92 45 — (1) Cross currency swap agreements 1,200 1,200 39 — — (50) Total Derivatives Designated as Hedging Instruments 5,743 6,444 195 304 — (109) Derivatives Not Designated as Hedging Instruments: Foreign currency exchange contracts 11,278 14,829 278 92 (282) (91) Total Derivatives at Fair Value $ 17,021 $ 21,273 $ 473 $ 396 $ (282) $ (200) All derivative assets are presented in Other current assets or Other assets. All derivative liabilities are presented in Accrued liabilities or Other liabilities. In addition to the foreign currency derivative contracts designated as net investment hedges, certain of the Company's foreign currency denominated debt instruments are designated as net investment hedges. The carrying value of those debt instruments designated as net investment hedges, which includes the adjustment for the foreign currency transaction gain or loss on those instruments, was $4,074 million and $4,414 million as of December 31, 2021 and 2020, respectively. Interest rate swap agreements are designated as hedge relationships with gains or losses on the derivative recognized in Interest and other financial charges offsetting the gains and losses on the underlying debt being hedged. Gains and losses on interest rate swap agreements recognized in earnings were $135 million of expense, $169 million of income and $70 million of expense for the years ended December 31, 2021, 2020 and 2019, respectively.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measures	FAIR VALUE MEASUREMENTS The accounting guidance for fair value measurements and disclosures establishes a three-level fair value hierarchy. • Level 1 - Inputs are based on quoted prices in active markets for identical assets and liabilities. • Level 2 - Inputs are based on observable inputs other than quoted prices in active markets for identical or similar assets and liabilities. • Level 3 - One or more inputs are unobservable and significant. Financial and nonfinancial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis: December 31, 2021 2020 Assets: Foreign currency exchange contracts $ 374 $ 202 Available for sale investments 742 1,118 Interest rate swap agreements 60 194 Cross currency swap agreements 39 — Investments in equity securities 57 11 Liabilities: Foreign currency exchange contracts $ 282 $ 150 Cross currency swap agreements — 50 The foreign currency exchange contracts, interest rate swap agreements, and cross currency swap agreements are valued using broker quotations, or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within level 2. The Company also holds investments in commercial paper, certificates of deposits, and time deposits that are designated as available for sale, as well as investments in equity securities, which are valued using published prices based on observable market data. As such, these investments are classified within level 2. The Company holds certain available for sale investments in U.S. government and corporate debt securities, as well as investments in equity securities, which are valued utilizing published prices based on quoted market pricing, which are classified within level 1. The carrying value of cash and cash equivalents, trade accounts and notes receivables, payables, commercial paper and short-term borrowings contained in the Consolidated Balance Sheet approximates fair value. The following table sets forth the Company’s financial assets and liabilities that were not carried at fair value: December 31, 2021 December 31, 2020 Carrying Fair Carrying Fair Assets: Short-term investment $ 34 $ 34 $ — $ — Long-term receivables 170 152 137 132 Long-term investment 366 366 — — Liabilities: Long-term debt and related current maturities $ 16,057 $ 17,022 $ 18,787 $ 20,176 The Company determined the fair value of the long-term receivables by utilizing transactions in the listed markets for identical or similar assets. As such, the fair value of these receivables is considered level 2.

Share-based Payment Arrangement [Abstract]
Share-based Payment Arrangement [Text Block]	The 2016 Stock Incentive Plan of Honeywell International Inc. and its Affiliates (2016 Plan) and 2016 Stock Plan for Non-Employee Directors of Honeywell International Inc. (2016 Directors Plan) were both approved by the shareowners at the Annual Meeting of Shareowners effective on April 25, 2016. At December 31, 2021, there were 32,337,638, and 815,299 shares of Honeywell common stock available for future grants under terms of the 2016 Plan and 2016 Directors Plan, respectively. STOCK OPTIONS The exercise price, term and other conditions applicable to each option granted under the Company's stock plans are generally determined by the Management Development and Compensation Committee of the Board of Directors. The exercise price of stock options is set on the grant date and may not be less than the fair market value per share of the Company's stock on that date. The fair value is recognized as an expense over the employee’s requisite service period (generally the vesting period of the award). Options generally vest over a four ten The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on implied volatilities from traded options on our common stock and historical volatility of the Company's common stock. The Company used a Monte Carlo simulation model to derive an expected term which represents an estimate of the time options are expected to remain outstanding. Such model uses historical data to estimate option exercise activity and post-vest termination behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. The following table summarizes the impact to the Consolidated Statement of Operations from stock options: Years Ended December 31, 2021 2020 2019 Compensation expense $ 55 $ 50 $ 47 Future income tax benefit recognized 11 10 10 The following table sets forth fair value per share information, including related weighted-average assumptions, used to determine compensation cost.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	ENVIRONMENTAL MATTERS The Company is subject to various federal, state, local and foreign government requirements relating to the protection of the environment. The Company believes that, as a general matter, the Company's policies, practices, and procedures are properly designed to prevent unreasonable risk of environmental damage and personal injury and that the handling, manufacture, use, and disposal of hazardous substances are in accordance with environmental and safety laws and regulations. However, mainly because of past operations and operations of predecessor companies, the Company, like other companies engaged in similar businesses, have incurred remedial response and voluntary cleanup costs for site contamination and are a party to lawsuits and claims associated with environmental and safety matters, including past production of products containing hazardous substances. Additional lawsuits, claims, and costs involving environmental matters are likely to continue to arise in the future. With respect to environmental matters involving site contamination, the Company continually conducts studies, individually or jointly with other potentially responsible parties, to determine the feasibility of various remedial techniques. It is the Company's policy to record appropriate liabilities for environmental matters when remedial efforts or damage claim payments are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory, or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology, and information related to individual sites, the Company does not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of the Company's recorded liabilities. The Company expects to fund expenditures for these matters from operating cash flow. The timing of cash expenditures depends on a number of factors, including the timing of remedial investigations and feasibility studies, the timing of litigation and settlements of remediation liability, personal injury and property damage claims, regulatory approval of cleanup projects, remedial techniques to be utilized, and agreements with other parties. The following table summarizes information concerning our recorded liabilities for environmental costs: Years Ended December 31, 2021 2020 2019 Beginning of year $ 660 $ 709 $ 755 Accruals for environmental matters deemed probable and reasonably estimable 168 173 213 Environmental liability payments (210) (216) (256) Other — (6) (3) End of year $ 618 $ 660 $ 709 Environmental liabilities are included in the following balance sheet accounts: December 31, 2021 2020 Accrued liabilities $ 225 $ 225 Other liabilities 393 435 $ 618 $ 660 The Company does not currently possess sufficient information to reasonably estimate the amounts of environmental liabilities to be recorded upon future completion of studies, litigation or settlements, and neither the timing nor the amount of the ultimate costs associated with environmental matters can be determined, although they could be material to the Company's consolidated results of operations and operating cash flows in the periods recognized or paid. However, considering the Company's past experience and existing reserves, the Company does not expect that environmental matters will have a material adverse effect on its consolidated financial position. In conjunction with the Resideo spin-off, the Company entered into an indemnification and reimbursement agreement with a Resideo subsidiary, pursuant to which Resideo’s subsidiary has an ongoing obligation to make cash payments to Honeywell in amounts equal to 90% of Honeywell’s annual net spending for environmental matters at certain sites as defined in the agreement. The amount payable to Honeywell in any given year is subject to a cap of $140 million, and the obligation will continue until the earlier of December 31, 2043, or December 31 of the third consecutive year during which the annual payment obligation is less than $25 million. Reimbursements associated with this agreement are collected from Resideo quarterly and were $140 million in both 2021 and 2020 and offset operating cash outflows incurred by the Company. As the Company incurs costs for environmental matters deemed probable and reasonably estimable related to the sites covered by the indemnification and reimbursement agreement, a corresponding receivable from Resideo for 90% of such costs is also recorded. This receivable amount recorded in 2021 and 2020 was $146 million and $146 million, respectively. As of December 31, 2021, Other current assets and Other assets included $140 million and $457 million, respectively, for the short-term and long-term portion of the receivable amount due from Resideo under the indemnification and reimbursement agreement. As of December 31, 2020, Other current assets and Other assets included $140 million and $451 million, respectively, for the short-term and long-term portion of the receivable amount due from Resideo under the indemnification and reimbursement agreement. ASBESTOS RELATED LIABILITIES Honeywell is named in asbestos-related personal injury claims related to North American Refractories Company (NARCO), which was sold in 1986, and the Bendix Friction Materials (Bendix) business, which was sold in 2014. The following tables summarize information concerning NARCO and Bendix asbestos-related balances: Year Ended December 31, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Bendix NARCO Total Bendix NARCO Total Bendix NARCO Total Beginning of year $ 1,441 $ 779 $ 2,220 $ 1,499 $ 858 $ 2,357 $ 1,623 $ 891 $ 2,514 Accrual for update to estimated liability 64 31 95 80 18 98 78 22 100 Change in estimated cost of future claims 29 — 29 42 — 42 (22) — (22) Update of expected resolution values for pending claims 3 — 3 10 — 10 (4) — (4) Asbestos related liability payments (165) (121) (286) (190) (97) (287) (176) (55) (231) End of year $ 1,372 $ 689 $ 2,061 $ 1,441 $ 779 $ 2,220 $ 1,499 $ 858 $ 2,357 INSURANCE RECOVERIES FOR ASBESTOS RELATED LIABILITIES Year Ended December 31, 2021 Year Ended December 31, 2020 Year Ended December 31, 2019 Bendix NARCO Total Bendix NARCO Total Bendix NARCO Total Beginning of year $ 148 $ 254 $ 402 $ 153 $ 281 $ 434 $ 170 $ 307 $ 477 Probable insurance recoveries related to estimated liability 7 — 7 10 — 10 3 — 3 Insurance receipts for asbestos related liabilities (13) (33) (46) (33) (25) (58) (39) (29) (68) Insurance receivables settlements and write offs — — — 18 (2) 16 19 3 22 End of year $ 142 $ 221 $ 363 $ 148 $ 254 $ 402 $ 153 $ 281 $ 434 NARCO and Bendix asbestos related balances are included in the following balance sheet accounts: December 31, 2021 2020 Other current assets $ 41 $ 36 Insurance recoveries for asbestos related liabilities 322 366 $ 363 $ 402 Accrued liabilities $ 261 $ 300 Asbestos related liabilities 1,800 1,920 $ 2,061 $ 2,220 NARCO Products – NARCO manufactured high-grade, heat-resistant, refractory products for various industries. Honeywell’s predecessor, Allied Corporation, owned NARCO from 1979 to 1986. Allied Corporation sold the NARCO business in 1986 and entered into a cross-indemnity agreement which included an obligation to indemnify the purchaser for asbestos claims, arising primarily from alleged occupational exposure to asbestos-containing refractory brick and mortar for high-temperature applications. NARCO ceased manufacturing these products in 1980 and filed for bankruptcy in January 2002, at which point in time all then current and future NARCO asbestos claims were stayed against both NARCO and Honeywell pending the reorganization of NARCO. The Company established its initial liability for NARCO asbestos claims in 2002. NARCO emerged from bankruptcy in April 2013, at which time a federally authorized 524(g) trust was established to evaluate and resolve all existing NARCO asbestos claims (the Trust). Both Honeywell and NARCO are protected by a permanent channeling injunction barring all present and future individual actions in state or federal courts and requiring all asbestos-related claims based on exposure to NARCO asbestos-containing products to be made against the Trust. The NARCO Trust Agreement (TA) and the NARCO Trust Distribution Procedures (TDP) set forth the structure and operating rules of the Trust, and established Honeywell’s evergreen funding obligations. In accordance with the TA, the Trust is eligible to receive cash dividends from Harbison-Walker International Inc. (HWI), the reorganized and renamed entity that emerged from the NARCO bankruptcy. HWI cash dividends are required to be used to pay asbestos-related claims which qualify for payment under the TDP (Annual Contribution Claims) until those funds are exhausted, at which point Honeywell’s funding obligation, subject to an annual cap of $145 million, is triggered. The Trust received dividend payments from HWI in 2021. The Company is also required to fund amounts owed pursuant to settlement agreements reached during the pendency of the NARCO bankruptcy proceedings that provide for the right to submit claims to the Trust subject to qualification under the terms of the settlement agreements and TDP (Pre-Established Unliquidated Claims), as well as fund the annual operating costs of the Trust. There is no annual funding cap relative to Pre-Established Unliquidated Claims. The operating rules per the TDP define criteria claimants must meet for a claim to be considered valid and paid, which include adequate medical evidence of the claimant’s asbestos-related condition and credible evidence of exposure to a specific NARCO asbestos-containing product. The TDP allows Honeywell to audit claim support documents against these criteria. Once operational in 2014, the Trust began to receive, process and pay claims. The Company identified several issues with the way the Trust was adhering to the TDP in audits subsequent to the Trust becoming operational. The Company consistently raised with the Trust concern that the Trust adopted an improper practice of paying claimants who have not demonstrated the requisite exposure. The Trust refused to alter its practices for payment of claims, and in September 2021, Honeywell filed suit against the Trust in the United States Bankruptcy Court for the Western District of Pennsylvania (Bankruptcy Court) alleging that the Trust has breached its duties in managing the Trust, including breaches of certain provisions of the TA and TDP. Honeywell's lawsuit seeks appropriate relief preventing the Trust from continuing these practices. The Trust also filed suit against Honeywell, alleging Honeywell has breached its obligations under the Trust's governing documents. Honeywell moved to dismiss the Trust’s suit, and on December 15, 2021, the Bankruptcy Court granted Honeywell’s motion to dismiss subject to granting the Trust leave to file an amended complaint. On December 28, 2021, the Trust filed an answer with counterclaims in response to Honeywell’s complaint and in lieu of filing an amended complaint. At this time, the Company cannot predict the outcome of these matters, or the potential impact on the asbestos-related liabilities. Due to the bankruptcy filing in 2002, claimants were not permitted to file additional claims until the Trust became operative in 2014. As a consequence, there was a large backlog of claims filed with the Trust upon it becoming operative in 2014 through December 31, 2017, the date by which these claims had to be filed or else be barred by the expiration of the statute of limitations. Therefore, the claims filing rate did not start to normalize until 2018 and thereafter. As a result, between 2002 and 2018, the Company lacked a history of sufficiently reliable claims data to derive a reasonable estimate of its NARCO asbestos-related liability, and the Company continued to update its original estimate, as appropriate, using all available information. Beginning in 2020, with three years of sufficiently reliable claims data, the Company updated its estimate of the NARCO asbestos-related liability. The estimate for the resolution of asserted Annual Contribution Claims and Pre-Established Unliquidated Claims uses average payment values for the relevant historical period. The estimate for unasserted claims is based on historic and anticipated claims filing experience and payment rates, disease classifications and type of claim, and average payment values by the Trust for the relevant historical period. The Company utilizes an asbestos liability valuation specialist to support the preparation of the NARCO asbestos-related liability estimates during the fourth quarter each year. The Company's estimates, which involve significant management judgment, and consider multiple scenarios, include all years of epidemiological disease projection through 2059. The NARCO asbestos-related liability reflects an estimate for the resolution of Annual Contribution Claims and Pre-Established Unliquidated Claims filed with the Trust, as well as for unasserted Annual Contribution Claims and Pre-Established Unliquidated Claims. The NARCO asbestos-related liability excludes the annual operating expenses of the Trust which are expensed as they are incurred. The Company's NARCO-related insurance receivable reflects coverage which reimburses Honeywell for portions of NARCO-related claims and defense costs. This coverage is provided by a large number of insurance policies written by dozens of insurance companies in both the domestic insurance market and the London excess market. Honeywell's NARCO-related insurance receivable is an estimate of the probable amount of insurance that is recoverable for asbestos claims. The Company's judgments related to the Company's insurance carriers and insurance coverages are reasonable and consistent with Honeywell's historical dealings and Honeywell's knowledge of any pertinent solvency issues surrounding insurers. Bendix Products – Bendix manufactured automotive brake linings that contained chrysotile asbestos in an encapsulated form. Claimants consist largely of individuals who allege exposure to asbestos from brakes from either performing or being in the vicinity of individuals who performed brake replacements. The following tables present information regarding Bendix related asbestos claims activity: Claims Activity Years Ended December 31, 2021 2020 Claims Unresolved at the beginning of year 6,242 6,480 Claims Filed 2,611 2,233 Claims Resolved (2,452) (2,471) Claims Unresolved at the end of year 6,401 6,242 Disease Distribution of Unresolved Claims Years Ended December 31, 2021 2020 Mesothelioma and Other Cancer Claims 3,760 3,422 Nonmalignant Claims 2,641 2,820 Total Claims 6,401 6,242 Honeywell has experienced average resolution values per claim excluding legal costs as follows: Years Ended December 31, 2021 2020 2019 2018 2017 (in whole dollars) Malignant claims $ 56,000 $ 61,500 $ 50,200 $ 55,300 $ 56,000 Nonmalignant claims $ 400 $ 550 $ 3,900 $ 4,700 $ 2,800 It is not possible to predict whether resolution values for Bendix-related asbestos claims will increase, decrease or stabilize in the future. The Consolidated Financial Statements reflect an estimated liability for resolution of asserted (claims filed as of the financial statement date) and unasserted Bendix-related asbestos claims, which exclude the Company’s ongoing legal fees to defend such asbestos claims which will continue to be expensed as they are incurred. The Company reflects the inclusion of all years of epidemiological disease projection through 2059 when estimating the liability for unasserted Bendix-related asbestos claims. Such liability for unasserted Bendix-related asbestos claims is based on historic and anticipated claims filing experience and dismissal rates, disease classifications, and resolution values in the tort system for the previous five years. The Company has valued Bendix asserted and unasserted claims using average resolution values for the previous five years. The Company updates the resolution values used to estimate the cost of Bendix asserted and unasserted claims during the fourth quarter each year. The Company's insurance receivable corresponding to the liability for settlement of asserted and unasserted Bendix asbestos claims reflects coverage which is provided by a large number of insurance policies written by dozens of insurance companies in both the domestic insurance market and the London excess market. Based on the Company's ongoing analysis of the probable insurance recovery, insurance receivables are recorded in the financial statements simultaneous with the recording of the estimated liability for the underlying asbestos claims. This determination is based on the Company's analysis of the underlying insurance policies, historical experience with insurers, ongoing review of the solvency of insurers, judicial determinations relevant to insurance programs, and consideration of the impacts of any settlements reached with the Company's insurers. On October 31, 2018, David Kanefsky (Plaintiff), a Honeywell shareholder, filed a putative class action complaint in the U.S. District Court for the District of New Jersey (the Court) alleging violations of the Securities Exchange Act of 1934 and Rule 10b-5 related to the prior accounting for Bendix asbestos claims. An Amended Complaint was filed on December 30, 2019, and on February 7, 2020, the Company filed a Motion to Dismiss. On May 18, 2020, the Court denied the Motion to Dismiss. On December 7, 2021, the parties filed a Stipulation of Settlement (Settlement Agreement) and Plaintiff filed a motion for preliminary approval of the Settlement Agreement, which includes payment by Honeywell of $10 million to settle the claims in dispute. Honeywell continues to believe the claims lack merit and denies wrongdoing as well as any liability for the claims made against Honeywell in the action. The Settlement Agreement remains subject to final court approval and other conditions. GARRETT LITIGATION AND BANKRUPTCY PROCEEDINGS In conjunction with the Garrett spin-off, the Company entered into a binding indemnification and reimbursement agreement (Garrett Indemnity) and a binding tax matters agreement (Tax Matters Agreement) with Garrett and a Garrett subsidiary. On December 2, 2019, Garrett and Garrett ASASCO Inc. filed a Summons with Notice and commenced a lawsuit in the Commercial Division of the Supreme Court of the State of New York, County of New York (the State Court), seeking to invalidate the Garrett Indemnity. Garrett sought damages and a declaratory judgment based on various claims set forth in the Summons with Notice. On July 17, 2020, the Company received a notice from Garrett asserting that the Company had caused material breaches of the Tax Matters Agreement and that the Tax Matters Agreement was unenforceable. On September 20, 2020, Garrett and 36 of its affiliates filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On September 24, 2020, Garrett moved the existing State Court litigation against Honeywell to the Bankruptcy Court. For the year ended December 31, 2020, the Company reviewed the aggregate carrying value of the receivable amounts due in connection with the Garrett Indemnity and Tax Matters Agreement and reduced the aggregate carrying value of the receivable by $509 million to reflect the present value of the amounts owed to the Company over the full term of these agreements. On April 26, 2021, the Bankruptcy Court confirmed Garrett’s amended Chapter 11 plan of reorganization (the Confirmed Plan), and on April 30, 2021 (the Effective Date), Garrett emerged from bankruptcy. On the Effective Date, and in accordance with the Confirmed Plan, (i) the Company received from Garrett an initial payment of $375 million and 834.8 million shares of Garrett's Series B Preferred Stock in full and final satisfaction of the Garrett Indemnity and Tax Matters Agreement, (ii) the Garrett Indemnity and Tax Matters Agreement were terminated, (iii) the Company and Garrett mutually released each other from the claims asserted in all pending legal actions related to the Garrett Indemnity and Tax Matters Agreement, and (iv) all pending litigation between the Company and Garrett in connection with those agreements was resolved. The original Series B Preferred Stock Certificate of Designation provides for mandatory redemptions by Garrett of $35 million in 2022 and $100 million per year from 2023 to 2030 (inclusive) at the anniversary of the Effective Date, unless (i) Garrett’s consolidated EBITDA as of the end of the most recently completed fiscal year is less than $425 million, or (ii) Garrett does not have sufficient funds available to pay the redemption, at which point the redemption amounts past due will accrue interest. The Series B Preferred Stock Certificate of Designation also includes rights which allow (a) the Company to put the Series B Preferred Stock to Garrett if certain EBITDA conditions are met, and (b) Garrett to call the Series B Preferred Stock in whole or in part if certain EBITDA conditions are met. On September 30, 2021, Garrett filed an Amended and Restated Series B Preferred Stock Certificate of Designation (Amendment) with the Secretary of State of Delaware. The Amendment required Garrett to partially redeem a portion of the Series B Preferred Stock on or before March 31, 2022, such that the present value of remaining outstanding shares of the Series B Preferred Stock would be $400 million (First Partial Redemption), subject to applicable law, including that Garrett had funds legally available for the partial redemption. The First Partial Redemption would be applied to the latest scheduled redemption dates, beginning with the shares to be redeemed in 2030. The Amendment also provides that the Company cannot exercise its right to put the Series B Preferred Stock to Garrett until after December 31, 2022, subject to the EBITDA conditions described in the above section, unless the partial redemption does not occur on or before March 31, 2022. All other material terms and conditions in the Amendment were unchanged from the original Series B Preferred Stock Certificate of Designation. On December 16, 2021, Garrett filed a Second Amended and Restated Series B Preferred Stock Certificate of Designation (Second Amendment) with the Secretary of State of Delaware. The Second Amendment accelerates the First Partial Redemption from March 31, 2022, to December 30, 2021, and allows Garrett to partially redeem an additional portion of the Series B Preferred Stock on or before March 31, 2022, such that the present value of remaining outstanding shares of the Series B Preferred Stock will be $207 million (Second Partial Redemption). The Second Partial Redemption is subject to similar terms as the First Partial Redemption, including that Garrett has funds legally available for the partial redemption. However, the Second Partial Redemption is also contingent upon Garrett completing the First Partial Redemption and either (i) increasing their revolving credit facility, or (ii) the Garrett Board of Directors determining that Garrett otherwise has sufficient liquidity to effect the Second Partial Redemption. The Second Partial Redemption would be applied to the earliest scheduled redemptions beginning with the shares to be redeemed on April 30, 2022. On December 17, 2021, Garrett announced their intention to effect the First Partial Redemption on December 28, 2021, in the amount of $211 million, and plan to effect the Second Partial Redemption during the first quarter of 2022 for a corresponding payment of $200 million. On December 28, 2021, Garrett paid $211 million for the amount due as the First Partial Redemption. The Company recorded the Series B Preferred Stock at fair value at the Effective Date. The Company believes the present value of the mandatory redemptions is an appropriate basis for determining the fair value of the Series B Preferred Stock. The Company's present value reflects amortized cost determined by the present value of the mandatory redemptions discounted at 7.25%, which is the rate reflected in the Series B Preferred Stock Certificate of Designation. The discount amount will accrete into interest income over the mandatory redemption period. In addition to the Series B Preferred Stock, the Company subscribed for 4.2 million shares of Garrett's Series A Preferred Stock, which are convertible into Garrett’s Common Stock if certain conditions are met. Prior to and following Garrett’s emergence from bankruptcy, the Company also held 2.9 million shares of Garrett’s Common Stock. As of December 31, 2021, Short-term investments included $34 million and Investments and long-term receivables included $423 million for the Company's investments in Garrett's Series B Preferred Stock, Series A Preferred Stock and Common Stock. OTHER MATTERS The Company is subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of the Company's business, including matters relating to commercial transactions, government contracts, product liability, prior acquisitions and divestitures, employee benefit plans, intellectual property, and environmental, health and safety matters (including the matter described below). The Company recognizes liabilities for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in such matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Such matters include: • Petrobras and Unaoil – The Company continues to cooperate with investigations by the U.S. Department of Justice (DOJ), the Securities and Exchange Commission (SEC) and the Brazilian authorities relating to the Company's use of third parties who previously worked for the Company's UOP business in Brazil in relation to Petróleo Brasileiro S.A. (Petrobras) in connection with a project awarded in 2010. The investigations focus on compliance with the U.S. Foreign Corrupt Practices Act and similar Brazilian laws (the UOP Matters), and involve, among other things, document production and interviews with former and current management and employees. The DOJ and the SEC are also examining a matter involving a foreign subsidiary’s prior contract with Unaoil S.A.M. in Algeria executed in 2011. The Company continues to be engaged in discussions with the authorities with respect to a potential comprehensive resolution of these matters. As the discussions are both ongoing and at different stages with regards to each respective authority, there can be no assurance as to whether the Company will reach a resolution with such authorities or as to the potential timing, terms, or collateral consequences of any such resolution. As a result, the Company cannot predict the ultimate outcome of these UOP Matters or the potential impact on the Company. Based on available information to date, the Company estimates that a potential comprehensive resolution of these UOP Matters would result in a probable loss of at least $160 million, and the Company has recorded a charge in this amount in the Company's Consolidated Statement of Operations, and accrued a corresponding liability on the Consolidated Balance Sheet. Amounts payable to authorities pursuant to any potential final comprehensive resolution could differ from the amount recorded in the Company's consolidated financial statements. Based on available information to date, the Company does not expect that any such difference would be material with respect to the Company's consolidated financial position. Given the uncertainty inherent in litigation and investigations, the Company does not believe it is possible to develop estimates of reasonably possible losses (or a range of possible losses) in excess of current accruals for such matters. Considering the Company's past experience and existing accruals, the Company does not expect the outcome of such matters, either individually or in the aggregate, to have a material adverse effect on the Company's consolidated financial position. Because most contingencies are resolved over long periods of time, potential liabilities are subject to change due to new developments, changes in settlement strategy or the impact of evidentiary requirements, which could cause us to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company's consolidated results of operations or operating cash flows in the periods recognized or paid. WARRANTIES AND GUARANTEES In the normal course of business, the Company issues product warranties and product performance guarantees. The Company accrues for the estimated cost of product warranties and performance guarantees based on contract terms and historical experience at the time of sale. Adjustments to initial obligations for warranties and guarantees are made as changes to the obligations become reasonably estimable. The following table summarizes information concerning the Company's recorded obligations for product warranties and product performance guarantees. Years Ended December 31, 2021 2020 2019 Beginning of year $ 243 $ 269 $ 310 Accruals for warranties/guarantees issued during the year 146 164 173 Adjustment of pre-existing warranties/guarantees (7) (18) (34) Settlement of warranty/guarantee claims (159) (172) (180) End of year $ 223 $ 243 $ 269 Product warranties and product performance guarantees are included in the following balance sheet accounts: December 31, 2021 2020 Accrued liabilities $ 180 $ 183 Other liabilities 43 60 $ 223 $ 243

PENSION AND OTHER POSTRETIREMEN

PENSION AND OTHER POSTRETIREMENT BENEFITS	12 Months Ended
	Dec. 31, 2021
Retirement Benefits, Description [Abstract]
Pension and Other Postretirement Benefits	The Company sponsors a number of both funded and unfunded U.S. and non-U.S. defined benefit pension plans. Pension benefits for many of the Company's U.S. employees are provided through non-contributory, qualified and non-qualified defined benefit plans. All non-union hourly and salaried employees joining Honeywell for the first time after December 31, 2012, are not eligible to participate in Honeywell’s U.S. defined benefit pension plans. The Company also sponsors defined benefit pension plans which cover non-U.S. employees who are not U.S. citizens, in certain jurisdictions, principally the UK, Netherlands, Germany, and Canada. Other pension plans outside of the U.S. are not material to the Company either individually or in the aggregate. The Company also sponsors postretirement benefit plans that provide health care benefits and life insurance coverage mainly to U.S. eligible retirees. None of Honeywell’s U.S. employees are eligible for a retiree medical subsidy from the Company. In addition, the vast majority of Honeywell’s U.S. retirees either have no Company subsidy or have a fixed-dollar subsidy amount. This significantly limits the Company's exposure to the impact of future health care cost increases. The retiree medical and life insurance plans are not funded. Claims and expenses are paid from the Company's cash flows from operations. The following tables summarize the balance sheet impact, including the benefit obligations, assets and funded status associated with the Company's significant pension and other postretirement benefit plans. Pension Benefits U.S. Plans Non-U.S. Plans 2021 2020 2021 2020 Change in benefit obligation: Benefit obligation at beginning of year $ 18,054 $ 17,283 $ 7,670 $ 6,897 Service cost 105 99 26 23 Interest cost 306 461 77 106 Plan amendments — — (3) 2 Actuarial (gains) losses (1) 141 1,331 (403) 509 Benefits paid (1,221) (1,100) (249) (246) Settlements and curtailments — (21) — — Foreign currency translation — — (121) 291 Other 6 1 2 88 Benefit obligation at end of year 17,391 18,054 6,999 7,670 Change in plan assets: Fair value of plan assets at beginning of year 20,396 18,995 8,450 7,307 Actual return on plan assets 1,344 2,475 166 918 Company contributions 35 46 101 116 Benefits paid (1,221) (1,100) (249) (246) Settlements and curtailments — (21) — — Foreign currency translation — — (74) 253 Other 6 1 2 102 Fair value of plan assets at end of year 20,560 20,396 8,396 8,450 Funded status of plans $ 3,169 $ 2,342 $ 1,397 $ 780 Amounts recognized in Consolidated Balance Sheet consist of: Prepaid pension benefit cost (2) $ 3,528 $ 2,695 $ 2,105 $ 1,688 Accrued pension liabilities—current (3) (33) (29) (14) (14) Accrued pension liabilities—noncurrent (4) (326) (324) (694) (894) Net amount recognized $ 3,169 $ 2,342 $ 1,397 $ 780 (1) The actuarial losses incurred in 2021 related to the Company's U.S. plans are primarily the result of changes in demographic experience and demographic assumptions, partially offset by actuarial gains due to an increase in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2021 compared to December 31, 2020. Actuarial gains incurred in 2021 related to the Company's non-U.S. plans are primarily the result of an increase in the discount rate assumption used to estimate the benefit obligations as of December 31, 2021 compared to December 31, 2020. Actuarial losses incurred in 2020 related to the Company's U.S. and non-U.S. plans are primarily the result of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2020 compared to December 31, 2019.

Pension Benefits U.S. Plans Non-U.S. Plans 2021 2020 2019 2021 2020 2019 Actuarial assumptions used to determine benefit obligations as of December 31: Discount rate 2.87 % 2.50 % 3.22 % 1.79 % 1.23 % 1.81 % Expected annual rate of compensation increase 3.25 % 3.25 % 3.25 % 2.56 % 2.43 % 2.47 % Actuarial assumptions used to determine net periodic benefit (income) cost for years ended December 31: Discount rate—benefit obligation 2.50 % 3.22 % 4.35 % 1.24 % 1.81 % 2.63 % Discount rate—service cost 2.68 % 3.33 % 4.47 % 1.00 % 1.48 % 2.26 % Discount rate—interest cost 1.76 % 2.76 % 3.94 % 1.00 % 1.56 % 2.34 % Expected rate of return on plan assets 6.15 % 6.15 % 6.75 % 4.03 % 4.66 % 5.14 % Expected annual rate of compensation increase 3.25 % 3.25 % 3.25 % 2.43 % 2.47 % 2.46 % Other Postretirement Benefits 2021 2020 2019 Actuarial assumptions used to determine benefit obligations as of December 31: Discount rate 2.66 % 2.20 % 3.03 % Actuarial assumptions used to determine net periodic benefit cost for years ended December 31: Discount rate (1) 2.20 % 2.36 % 4.07 % (1) Discount rate was 3.03% for January 1, 2020 through September 30, 2020. The rate was changed to 2.36% for the remainder of 2020 due to a Plan remeasurement as of October 1, 2020. The discount rate for the Company's U.S. pension and other postretirement benefits plans reflects the current rate at which the associated liabilities could be settled at the measurement date of December 31. To determine discount rates for the Company's U.S. pension and other postretirement benefit plans, the Company uses a modeling process that involves matching the expected cash outflows of the Company's benefit plans to a yield curve constructed from a portfolio of high quality, fixed-income debt instruments. The Company uses the single weighted-average yield of this hypothetical portfolio as a discount rate benchmark. The Company utilizes a full yield curve approach in the estimation of the service and interest cost components of net periodic pension benefit (income) for the Company's significant pension plans. This approach applies the specific spot rates along the yield curve used in the determination of the pension benefit obligation to their underlying projected cash flows and provides a more precise measurement of service and interest costs by improving the correlation between projected cash flows and their corresponding spot rates. For the Company's U.S. pension plans, the single weighted average spot rates used to determine service and interest costs for 2022 are 2.97% and 2.26%. The discount rate used to determine the other postretirement benefit obligation is lower principally due to a shorter expected duration of other postretirement plan obligations as compared to pension plan obligations. The Company plans to use an expected rate of return on U.S. plan assets of 6.40% for 2022, which represents an increase from the 6.15% assumption used for 2021. The Company's asset return assumption is based on historical plan asset returns over varying long-term periods combined with current market conditions and broad asset mix considerations with a focus on long-term trends rather than short-term market conditions. The Company reviews the expected rate of return on an annual basis and revise it as appropriate. For non-U.S. benefit plans actuarial assumptions reflect economic and market factors relevant to each country. PENSION BENEFITS The following amounts relate to the Company's significant pension plans with accumulated benefit obligations exceeding the fair value of plan assets: December 31, U.S. Plans Non-U.S. Plans 2021 2020 2021 2020 Projected benefit obligation $ 359 $ 353 $ 964 $ 2,116 Accumulated benefit obligation $ 346 $ 341 $ 932 $ 2,042 Fair value of plan assets $ — $ — $ 256 $ 1,208 The accumulated benefit obligation for the Company's U.S. defined benefit pension plans was $17.3 billion and $17.9 billion and for the Company's Non-U.S. defined benefit pension plans was $6.9 billion and $7.6 billion at December 31, 2021 and 2020. The Company's asset investment strategy for its U.S. pension plans focuses on maintaining a diversified portfolio using various asset classes in order to achieve the Company's long-term investment objectives on a risk adjusted basis. The Company's long-term target allocations are as follows: 55%-70% fixed income securities and cash, 25%-40% equity securities, 5%-10% real estate investments, and 10%-20% other types of investments. Equity securities include publicly-traded stock of companies located inside the United States. Fixed income securities include corporate bonds of companies from diversified industries, mortgage-backed securities, and U.S. Treasuries. Real estate investments include direct investments in commercial properties and investments in real estate funds. Other types of investments include investments in private equity that follow several different strategies. The Company reviews its assets on a regular basis to ensure that the Company is within the targeted asset allocation ranges and, if necessary, asset balances are adjusted back within target allocations. The Company's non-U.S. pension assets are typically managed by decentralized fiduciary committees with the Honeywell Corporate Investments group providing funding and investment guidance. The Company's non-U.S. investment policies are different for each country as local regulations, funding requirements, and financial and tax considerations are part of the funding and investment allocation process in each country. In accordance with ASU 2015-07, “Fair Value Measurement (Topic 820)”, certain investments that are measured at fair value using the net asset value (NAV) per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in the following tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented for the total pension benefits plan assets. The fair values of both the Company's U.S. and non-U.S. pension plans assets by asset category are as follows: U.S. Plans December 31, 2021 Total Level 1 Level 2 Level 3 Equities: Honeywell common stock $ 3,251 $ 3,251 $ — $ — U.S. equities — — — — Fixed income: Short term investments 1,767 1,767 — — Government securities 1,373 — 1,373 — Corporate bonds 9,588 — 9,588 — Mortgage/Asset-backed securities 1,072 — 1,072 — Insurance contracts 8 — 8 — Direct investments: Direct private investments 1,336 — — 1,336 Real estate properties 843 — — 843 Total $ 19,238 $ 5,018 $ 12,041 $ 2,179 Investments measured at NAV: Private funds 1,244 Real estate funds 14 Commingled Funds 64 Total assets at fair value $ 20,560 U.S. Plans December 31, 2020 Total Level 1 Level 2 Level 3 Equities: Honeywell common stock $ 3,319 $ 3,319 $ — $ — U.S. equities — — — — Fixed income: Short term investments 1,314 1,314 — — Government securities 1,520 — 1,520 — Corporate bonds 10,190 — 10,190 — Mortgage/Asset-backed securities 982 — 982 — Insurance contracts 7 — 7 — Direct investments: Direct private investments 1,220 — — 1,220 Real estate properties 651 — — 651 Total $ 19,203 $ 4,633 $ 12,699 $ 1,871 Investments measured at NAV: Private funds 1,105 Real estate funds 26 Commingled funds 62 Total assets at fair value $ 20,396 Non-U.S. Plans December 31, 2021 Total Level 1 Level 2 Level 3 Equities: U.S. equities $ 229 $ 1 $ 228 $ — Non-U.S. equities 824 — 824 — Fixed income: Short-term investments 571 571 — — Government securities 3,893 — 3,893 — Corporate bonds 1,681 — 1,681 — Mortgage/Asset-backed securities 79 — 79 — Insurance contracts 123 — 123 — Insurance buy-in contracts 691 — — 691 Investments in private funds: Private funds 74 — 41 33 Real estate funds 163 — — 163 Total $ 8,328 $ 572 $ 6,869 $ 887 Investments measured at NAV: Private funds 17 Real estate funds 51 Total assets at fair value $ 8,396 Non-U.S. Plans December 31, 2020 Total Level 1 Level 2 Level 3 Equities: U.S. equities $ 207 $ — $ 207 $ — Non-U.S. equities 1,614 66 1,548 — Fixed income: Short-term investments 596 596 — — Government securities 3,105 — 3,105 — Corporate bonds 1,649 — 1,649 — Mortgage/Asset-backed securities 93 — 93 — Insurance contracts 142 — 142 — Insurance buy-in contracts 767 — — 767 Investments in private funds: Private funds 65 — 36 29 Real estate funds 147 — — 147 Total $ 8,385 $ 662 $ 6,780 $ 943 Investments measured at NAV: Private funds 18 Real estate funds 47 Total assets at fair value $ 8,450 The following table summarizes changes in the fair value of Level 3 assets for both U.S. and Non-U.S. plans: U.S. Plans Non-U.S. Plans Direct Real Estate Private Real Estate Insurance Buy-in Contracts Balance at December 31, 2019 $ 950 $ 619 $ 34 $ 150 $ — Actual return on plan assets: Relating to assets still held at year-end 100 (4) (5) (3) — Relating to assets sold during the year 53 — — — — Purchases 221 59 — — 767 Sales and settlements (104) (23) — — — Balance at December 31, 2020 1,220 651 29 147 767 Actual return on plan assets: Relating to assets still held at year-end 11 96 4 23 (76) Relating to assets sold during the year 174 — — 4 — Purchases 194 99 — — — Sales and settlements (263) (3) — (11) — Balance at December 31, 2021 $ 1,336 $ 843 $ 33 $ 163 $ 691 The Company enters into futures contracts to gain exposure to certain markets. Sufficient cash or cash equivalents are held by the Company's pension plans to cover the notional value of the futures contracts. At December 31, 2021 and 2020, the Company's U.S. plans had contracts with notional amounts of $4,415 million and $3,673 million. At December 31, 2021 and 2020, the Company's non-U.S. plans had contracts with notional amounts of $311 million and $564 million, respectively. In both the Company's U.S. and non-U.S. pension plans, the notional derivative exposure is related to outstanding equity and fixed income futures contracts. Common stocks, preferred stocks, real estate investment trusts, and short-term investments are valued at the closing price reported in the active market in which the individual securities are traded. Corporate bonds, mortgages/asset-backed securities, and government securities are valued either by using pricing models, bids provided by brokers or dealers, quoted prices of securities with similar characteristics or discounted cash flows and as such include adjustments for certain risks that may not be observable such as credit and liquidity risks. Certain securities are held in collective trust funds which are valued using net asset values provided by the administrators of the funds. Investments in private equity, debt, real estate and hedge funds and direct private investments are valued at estimated fair value based on quarterly financial information received from the investment advisor and/or general partner. Investments in real estate properties are valued on a quarterly basis using the income approach. Valuation estimates are periodically supplemented by third party appraisals. The insurance buy-in contracts represent policies held by the Honeywell UK Pension Scheme, whereby the cost of providing pension benefits to plan participants is funded by the policies. The cash flows from the policies are intended to match the pension benefits. The fair value of these policies is based on an estimate of the policies' exit price. The Company's funding policy for qualified defined benefit pension plans is to contribute amounts at least sufficient to satisfy regulatory funding standards. In 2021, 2020, and 2019, the Company was not required to make contributions to the U.S. pension plans and no contributions were made. The Company is not required to make any contributions to the U.S. pension plans in 2022. In 2021, contributions of $94 million were made to the non-U.S. pension plans to satisfy regulatory funding requirements. In 2022, the Company expects to make contributions of cash and/or marketable securities of approximately $11 million to the non-U.S. pension plans to satisfy regulatory funding standards. Contributions for both the U.S. and non-U.S. pension plans do not reflect benefits paid directly from Company assets. Benefit payments, including amounts to be paid from Company assets, and reflecting expected future service, as appropriate, are expected to be paid as follows: U.S. Plans Non-U.S. Plans 2022 $ 1,135 $ 261 2023 1,124 263 2024 1,115 268 2025 1,107 275 2026 1,097 284 2027-2031 5,152 1,455 OTHER POSTRETIREMENT BENEFITS December 31, 2021 2020 Assumed health care cost trend rate: Health care cost trend rate assumed for next year 6.50 % 7.00 % Rate that the cost trend rate gradually declines to 5.00 % 5.00 % Year that the rate reaches the rate it is assumed to remain at 2029 2029 Benefit payments reflecting expected future service, as appropriate, are expected to be paid as follows: Without Impact of Net of 2022 $ 27 $ 25 2023 25 24 2024 14 14 2025 14 13 2026 13 12 2027-2031 57 53

Segment Reporting [Abstract]
Segment Financial Data	Honeywell globally manages its business operations through four reportable operating segments. Segment information is consistent with how management reviews the businesses, makes investing and resource allocation decisions, and assesses operating performance. Honeywell’s senior management evaluates segment performance based on segment profit. Each segment’s profit is measured as segment income (loss) before taxes excluding general corporate unallocated expense, interest and other financial charges, stock compensation expense, pension and other postretirement income (expense), repositioning and other charges, and other items within Other (income) expense.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Accounting Principles	ACCOUNTING PRINCIPLES The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. The following is a description of Honeywell’s significant accounting policies.
Principles of Consolidation	PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements include the accounts of Honeywell International Inc. and all of its subsidiaries and entities in which a controlling interest is maintained. The Company's consolidation policy requires equity investments that the Company exercises significant influence over but do not control the investee and are not the primary beneficiary of the investee’s activities to be accounted for using the equity method. Investments through which the Company is not able to exercise significant influence over the investee and which the Company does not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation.
Reclassifications	RECLASSIFICATIONS Certain prior year amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS The Company considers the applicability and impact of all Accounting Standards Updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's consolidated statement of operations, balance sheet and cash flows (Consolidated Financial Statements). In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The standard’s amendments include changes in various subtopics of accounting for income taxes including, but not limited to, accounting for “hybrid” tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, intraperiod tax allocation exception to incremental approach, ownership changes in investments, interim-period accounting for enacted changes in tax law, and year-to-date loss limitation in interim-period tax accounting. Effective January 1, 2021, the Company adopted this standard. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounted principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope , to expand the scope of this guidance to include derivatives. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company will apply the guidance to impacted transactions during the transition period. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. This ASU should be applied prospectively to acquisitions occurring on or after the effective date of December 15, 2022, and early adoption is permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements.
Research and Development	RESEARCH AND DEVELOPMENT Research and development costs for projects are expensed as incurred, unless these costs relate to contracts with customers where the Company receives reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Cost of products and services sold and were $1,333 million, $1,334 million and $1,556 million for the years ended December 31, 2021, 2020 and 2019, respectively. Costs related to contracts with customers for customer-sponsored research and development projects are included as a contract cost and included in Cost of products and services sold when revenue from such contracts is recognized, consistent with the Company's sales recognition policies. This revenue was $1,284 million, $1,200 million and $1,079 million for the years ended December 31, 2021, 2020 and 2019, respectively.
Cash And Cash Equivalents	CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less.
Inventories	INVENTORIES Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. Carrying value adjustments for inventory obsolescence is equal to the difference between the cost and net realizable value. Net realizable value is the estimate selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost, including any asset retirement obligations, less accumulated depreciation. For financial reporting, the straight-line method of depreciation is used over the estimated useful lives of 10 to 50 years for buildings and improvements an d 3 to 16 years for machinery and equipment. Recognition of the fair value of obligations associated with the retirement of tangible long-lived assets is required when there is a legal obligation to incur such costs. Upon initial recognition of a liability, the cost is capitalized as part of the related long-lived asset and depreciated over the corresponding asset’s useful life.
Goodwill and Indefinite-Lived Intangible Assets	GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETSGoodwill and indefinite-lived intangible assets are subject to impairment testing annually as of March 31, or if a triggering event occurs or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. The Company completed its annual goodwill impairment test as of March 31, 2021, and determined that there was no impairment as of that date. The Company is not aware of any additional triggering events.
Finite-Lived Intangible Assets	FINITE-LIVED INTANGIBLE ASSETS Other intangible assets with determinable lives consist of customer lists, technology, patents and trademarks and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 22 years.
Foreign Currency Translation	FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income (loss). For subsidiaries operating in highly inflationary environments, inventories and property, plant and equipment, including related expenses, are remeasured at the exchange rate in effect on the date the assets were acquired, while monetary assets and liabilities are remeasured at year-end exchange rates. Remeasurement adjustments for these subsidiaries are included in earnings.
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS All derivative financial instruments are recorded on the balance sheet as assets or liabilities and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the changes in fair value of the derivatives are recorded in Accumulated other comprehensive income (loss) and subsequently recognized in earnings when the hedged items impact earnings. Derivative financial instruments designated as hedges must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged item. The Company elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and recognize the initial value of the excluded component in earnings using the amortization approach. For derivative instruments that are designated and qualify as a net investment hedge, the gain or loss is reported as a component of Other comprehensive income (loss) and recorded in Accumulated other comprehensive income (loss). The gain or loss will be subsequently reclassified into net earnings when the hedged net investment is either sold or substantially liquidated.
Leases	LEASES At the inception of a contract, the Company assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. All significant lease arrangements are generally recognized at lease commencement. Operating lease right-of-use (ROU) assets and lease liabilities are recognized at commencement. An ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases), and we recognize lease expense for these leases as incurred over the lease term. ROU assets represent the Company's right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses its incremental borrowing rate, which is based on the information available at the lease commencement date, in determining the present value of the lease payments. In determining the borrowing rate, the Company considers the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than U.S. dollar, the collateralized borrowing rate in the foreign currency using the U.S. dollar and foreign currency swap spread, when available.
Pension Benefits	PENSION BENEFITS The Company presents net periodic pensions costs by disaggregating the service cost component of such costs and reports those costs in the same line item or items in the Consolidated Statement of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of such costs are required to be presented separately from the service cost component.
Sales Recognition	SALES RECOGNITION Product and service sales are recognized when or as the Company transfers control of the promised products or services to its customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Service sales, principally representing repair, maintenance and engineering activities, are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as the Company performs on these contracts because of the continuous transfer of control to the customer. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for contracts because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost input method, the extent of progress towards completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on significant contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required. The customer funding for costs incurred for nonrecurring engineering and development activities of the Company's products under agreements with commercial customers is deferred and subsequently recognized as revenue as products are delivered to the customers. Additionally, expenses incurred, up to the customer agreed funded amount, are deferred as an asset and recognized as cost of sales when products are delivered to the customer. The deferred customer funding and costs result in recognition of deferred costs (asset) and deferred revenue (liability) on the Company's Consolidated Balance Sheet. Capitalized contract fulfillment costs were approximately $1.3 billion as of December 31, 2021 and 2020. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the years ended December 31, 2021, 2020 and 2019. Revenues for the Company's mechanical service programs are recognized as performance obligations that are satisfied over time, with recognition reflecting a series of distinct services using the output method. The terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, cash-based incentives, rebates, performance awards, or credits. The Company estimates variable consideration at the most likely amount the Company will receive from customers. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. The Company's estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.
Stock-Based Compensation Plans	STOCK-BASED COMPENSATION PLANS The principal awards issued under the Company's stock-based compensation plans, which are described in Note 15 Stock-Based Compensation Plans, are non-qualified stock options and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods (generally the vesting period of the equity award) and is included in Selling, general and administrative expenses. Forfeitures are estimated at the time of grant to recognize expense for those awards that are expected to vest and are based on the Company's historical forfeiture rates.
Income Taxes	INCOME TAXES Significant judgment is required in evaluating tax positions. The Company establishes reserves for income taxes when, despite the belief that tax positions are fully supportable, there remain certain positions that do not meet the minimum recognition threshold. The approach for evaluating certain and uncertain tax positions is defined by the authoritative guidance which determines when a tax position is more likely than not to be sustained upon examination by the applicable taxing authority. In the normal course of business, the Company and its subsidiaries are examined by various federal, state and foreign tax authorities. The Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of the Company's provision for income taxes. The Company continually assesses the likelihood and amount of potential adjustments and adjust the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a change in estimate become known. For additional information, see Note 5 Income Taxes.
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding.
Environmental	ENVIRONMENTAL The Company accrues costs related to environmental matters when it is probable that it has incurred a liability related to a contaminated site and the amount can be reasonably estimated. For additional information, see Note 19 Commitments and Contingencies.
Asbestos Related Liabilities and Insurance Recoveries	ASBESTOS RELATED LIABILITIES AND INSURANCE RECOVERIES The Company recognizes a liability for any asbestos related contingency that is probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos related matters, the Company records asbestos related insurance recoveries that are deemed probable. For additional information, see Note 19 Commitments and Contingencies.
Reimbursement Receivables [Policy Text Block]	REIMBURSEMENT RECEIVABLES In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into a reimbursement agreement under which Honeywell receives cash payments as reimbursement primarily related to net spending for environmental matters at certain sites as defined in the reimbursement agreement. Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell environmental spend, and the Company monitors the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay.
