Accounting Policies [Abstract]
Significant Accounting Policies	Significant accounting policies Basis of presentation . The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles in the United States (U.S. GAAP) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the full year. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended October 31, 2020. Basis of consolidation . The consolidated financial statements include the accounts of Nordson Corporation and its majority-owned and controlled subsidiaries. Investments in affiliates and joint ventures in which our ownership is 25% or less or in which we do not have control but have the ability to exercise significant influence, are accounted for under the cost method. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of estimates . The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Actual amounts could differ from these estimates. Revenue recognition . A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. Revenue is recognized when performance obligations under the terms of the contract with a customer are satisfied. Generally, our revenue results from short-term, fixed-price contracts and primarily is recognized as of a point in time when the product is shipped or at a later point when the control of the product transfers to the customer. Revenue for undelivered items is deferred and included within Accrued liabilities in our Condensed Consolidated Balance Sheets. Revenues deferred as of April 30, 2021 and 2020 were not material. However, for certain contracts related to the sale of customer-specific products within our Advanced Technology Solutions segment, revenue is recognized over time as we satisfy performance obligations because of the continuous transfer of control to the customer. The continuous transfer of control to the customer occurs as we enhance assets that are customer controlled and we are contractually entitled to payment for work performed to date plus a reasonable margin. As control transfers over time for these products or services, revenue is recognized based on progress toward completion of the performance obligations. The selection method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We have elected to use the input method – costs incurred for these contracts because it best depicts the transfer of products or services to the customer based on incurring costs on the contract. Under this method, revenues are recorded proportionally as costs are incurred. Contract assets recognized are recorded in Prepaid expenses and other current assets and contract liabilities are recorded in Accrued liabilities in our Condensed Consolidated Balance Sheets and were not material at April 30, 2021 and October 31, 2020. Revenue recognized over time is not material to our overall Consolidated Financial Statements. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services. Sales, value add, and other taxes we collect concurrently with revenue-producing activities are excluded from revenue. As a practical expedient, we may exclude the assessment of whether goods or services are performance obligations, if they are immaterial in the context of the contract, and combine these with other performance obligations. While payment terms and conditions vary by contract type, we have determined that our contracts generally do not include a significant financing component. We have elected to apply the practical expedient to treat all shipping and handling costs as fulfillment costs as a significant portion of these costs are incurred prior to transfer of control to the customer. We have also elected to apply the practical expedient to expense sales commissions as they are incurred as the amortization period resulting from capitalizing the costs is one year or less. These costs are recorded within Selling and administrative expenses in our Condensed Consolidated Statements of Income. We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term and is generally not material. Certain arrangements may include installation, installation supervision, training, and spare parts, which tend to be completed in a short period of time, at an insignificant cost, and utilizing skills not unique to us, and, therefore, are typically regarded as inconsequential or not material. We disclose disaggregated revenues by operating segment and geography in accordance with the revenue standard and on the same basis used internally by the chief operating decision maker for evaluating performance of operating segments and for allocating resources. Refer to our Operating Segments note. Earnings per share . Basic earnings per share are computed based on the weighted-average number of common shares outstanding during each year, while diluted earnings per share are based on the weighted-average number of common shares and common share equivalents outstanding. Common share equivalents consist of shares issuable upon exercise of stock options computed using the treasury stock method, as well as restricted shares and deferred stock-based compensation. Options with an exercise price higher than the average market price are excluded from the calculation of diluted earnings per share because the effect would be anti-dilutive. Options excluded from the calculation of diluted earnings per share for the three months ended April 30, 2021 and April 30, 2020 were 91 and 360, respectively. Options excluded from the calculation of diluted earnings per share for the six months ended April 30, 2021 and April 30, 2020 were 91 and 180, respectively.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Standards	Recently issued accounting standards New accounting guidance adopted: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326),” which changed the impairment model for most financial instruments. Prior guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflected losses once the losses are probable. We adopted the new standard on November 1, 2020 and are now applying a current expected credit loss model that requires recognizing an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of the update, including trade receivables. The standard requires judgment and consideration of historical information, current information, and reasonable and supportable forecasts, as well as the impact of any prepayments. In addition, we reviewed our business processes and controls to support the recognition and disclosure as required under the new standard. The adoption of this new standard did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other Internal – Use Software (Subtopic 350-40),” which is meant to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement), by providing guidance in determining when the arrangement includes a software license. We adopted the new standard on November 1, 2020. Hosted arrangements deemed to be in scope will follow the capitalization criteria for implementation costs as though they were internal-use computer software. There may be multiple elements besides the software license (such as: training, future upgrades, data conversion, and other elements) which require the allocation of the contract price to each of the elements; entities are to capitalize only those elements which meet the capitalization criteria. Capitalized implementation costs are amortized over the term of the hosted arrangement including consideration for renewal or termination options. In addition, we reviewed our business processes and controls to support the recognition and disclosure as required under the new standard. The adoption of this new standard did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued a new standard which removed, modified, and added certain disclosure requirements on fair value measurements. The guidance removed disclosure requirements pertaining to the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. For investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly. In addition, the amendment clarified that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The guidance added disclosure requirements for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period as well as the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. We adopted the new standard on November 1, 2020 with no material impact to the Consolidated Financial Statements. New accounting guidance issued and not yet adopted: In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20),” a new standard which addresses defined benefit plans. The amendments modify the following disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans: the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, amount and timing of plan assets expected to be returned to the employer, related party disclosure about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, and the effects of a one-percentage point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligations for postretirement health care benefits. A disclosure requirement was added for the explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Additionally, the standard clarifies disclosure requirements surrounding the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets and the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. It will be effective for us beginning November 1, 2021. Early adoption is permitted. We are currently assessing the impact this standard will have on our Consolidated Financial Statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (ASC 740) – Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. It will be effective for us beginning November 1, 2021. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. We are currently assessing the impact this standard will have on our Consolidated Financial Statements.

Business Combinations [Abstract]
Acquisitions	Acquisitions Business acquisitions have been accounted for using the acquisition method, with the acquired assets and liabilities recorded at estimated fair value on the dates of acquisition. The cost in excess of the net assets of the business acquired is included in goodwill. Operating results since the respective dates of acquisitions are included in the Condensed Consolidated Statements of Income. On September 1, 2020, we acquired 100 percent of the outstanding shares of vivaMOS Ltd. ("vivaMOS"), a developer and fabricator of high-end large-area complementary metal–oxide–semiconductor (CMOS) image sensors for a wide range of X-ray applications. We acquired vivaMOS for an aggregate purchase price of $17,154, net of cash and other closing adjustments of approximately $158, utilizing cash on hand. Based on the fair value of the assets acquired and the liabilities assumed, goodwill of $14,394 and identifiable intangible assets of $4,040 were recorded. The identifiable intangible assets consist primarily of $3,900 of technology (amortized over 10 years) and $140 of non-compete agreements (amortized over 3 years). Goodwill associated with this acquisition is not tax deductible. This acquisition is being reported in our Advanced Technology Solutions segment and the results of vivaMOS are not material to our Consolidated Financial Statements. As of April 30, 2021, the purchase price allocation remains preliminary as we complete our assessments of income taxes. On June 1, 2020, we acquired 100 percent of the outstanding shares of Fluortek, Inc. ("Fluortek"), a precision plastic extrusion manufacturer that provides custom dimensioned tubing to the medical device industry. We acquired Fluortek for an aggregate purchase price of $125,260, net of cash and other closing adjustments of approximately $515, utilizing cash on hand. Based on the fair value of the assets acquired and the liabilities assumed, property, plant and equipment and working capital – net of $19,843, goodwill of $76,047 and identifiable intangible assets of $29,370 were recorded. The identifiable intangible assets consist primarily of $19,700 of customer relationships (amortized over 12 years), $7,400 of technology (amortized over 10 years), $1,500 of tradenames (amortized over 10 years), and $770 of non-compete agreements (amortized over 5 years). Goodwill associated with this acquisition is tax deductible. This acquisition is being reported in our Advanced Technology Solutions segment and the results for Fluortek are not material to our Consolidated Financial Statements. As of April 30, 2021, the purchase price allocations remain preliminary as we complete our assessments of income taxes.

Discontinued Operations and Disposal Groups [Abstract]
Divestiture	Divestiture In the fourth quarter of 2020, we committed to a plan to sell our screws and barrels product line within our Industrial Precision Solutions operating segment and determined the criteria to be classified as held for sale were met. We entered into a letter of intent to sell the screws and barrels product line in October 2020 and in December 2020, entered into a definitive agreement with the buyer. The assets and liabilities were presented as held for sale in the Condensed Consolidated Balance Sheets and measured at the lower of carrying value or fair value less cost to sell from October 31, 2020 until the transaction was completed on February 1, 2021. Before measuring the fair value less costs to sell of the disposal group as a whole, we first reviewed individual assets and liabilities to determine if any fair value adjustments were required and concluded no individual asset impairments were required. Then, based on the definitive agreement entered into by us and the buyer, we determined the fair value of the disposal group to be equal to the selling price, less costs to sell. Based on this review, we recorded a non-cash, assets held for sale impairment charge of $87,371 in 2020. The assets and liabilities of the screws and barrels product line classified as held for sale at October 31, 2020 were as follows: October 31, 2020 Receivables - net $ 14,327 Inventories - net 9,854 Prepaid expenses and other current assets 696 Property, plant and equipment - net 58,950 Other assets 23,159 Impairment on carrying value (87,371) Assets held for sale $ 19,615 Accounts payable $ 4,625 Accrued liabilities 3,352 Other liabilities 5,171 Liabilities held for sale $ 13,148 Excluding the non-cash, assets held for sale impairment charge recorded in the fourth quarter of 2020, the operating results of the screws and barrels product line were not material to our Consolidated Financial Statements for any period presented. There were no significant adjustments to the loss recognized in 2020.

Credit Loss [Abstract]
Receivables	Receivables Our primary allowance for credit losses is the allowance for doubtful accounts, which is principally determined based on aging of receivables. Receivables are exposed to credit risk based on the customers' ability to pay which is influenced by, among other factors, their financial liquidity. We perform ongoing customer credit evaluation to maintain sufficient allowances for potential credit losses. Our segments perform credit evaluation and monitoring to estimate and manage credit risk through the review of customer information, credit ratings, approval and monitoring of customer credit limits, and assessment of market conditions. We may also require prepayments or bank guarantees from customers to mitigate credit risk. Our receivables are generally short-term in nature with a majority of receivables outstanding less than 90 days. Accounts receivable balances are written-off against the allowance if deemed uncollectible. Accounts receivable are net of an allowance for credit losses of $8,176 and $9,045 at April 30, 2021 and October 31, 2020, respectively. The change in the allowance for expected credit losses includes an immaterial accounting standard adoption impact from ASU 2016-13 of $396 for the six months ended April 30, 2021. The provision for losses on receivables was $301 and $404 for the three and six months ended April 30, 2021, respectively, compared to $751 and $1,535 for the same periods a year ago, respectively. The remaining change in the allowance for credit losses is principally related to the write-off of uncollectible accounts.

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended
	Apr. 30, 2021
Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-based compensation During the 2021 Annual Meeting of Shareholders, our shareholders approved the Nordson Corporation 2021 Stock Incentive and Award Plan (the “2021 Plan”) as the successor to the Amended and Restated 2012 Stock Incentive and Award Plan (the "2012 Plan"). The 2021 Plan provides for the granting of stock options, stock appreciation rights, restricted shares, restricted share units, performance shares, cash awards and other stock or performance-based incentives. A maximum of 900 common shares were authorized for grant under the 2021 Plan plus the number of shares that were available to be granted under the 2012 Plan for a combined total of 2,208 common shares available to be granted as of April 30, 2021. Stock Options Stock options may be granted to our employees and directors. Generally, options granted to employees may be exercised beginning one year from the date of grant at a rate not exceeding 25 percent per year and expire 10 years from the date of grant. Vesting accelerates upon a qualified termination in connection with a change in control. In the event of termination of employment due to early retirement or normal retirement at age 65, options granted within 12 months prior to termination are forfeited, and vesting continues post retirement for all other unvested options granted. In the event of disability or death, all unvested stock options granted within 12 months prior to termination (or at any time prior to December 28, 2017) fully vest. Termination for any other reason results in forfeiture of unvested options and vested options in certain circumstances. The amortized cost of options is accelerated if the retirement eligibility date occurs before the normal vesting date. Option exercises are satisfied through the issuance of treasury shares on a first-in, first-out basis. We recognized compensation expense related to stock options of $1,565 and $3,801 for the three and six months ended April 30, 2021, respectively, compared to $2,538 and $5,263 for the three and six months ended April 30, 2020, respectively. The following table summarizes activity related to stock options for the six months ended April 30, 2021: Number of Weighted- Aggregate Weighted Outstanding at October 31, 2020 1,487 $ 122.45 Granted 93 201.43 Exercised (176) 107.02 Forfeited or expired (19) 140.03 Outstanding at April 30, 2021 1,385 $ 129.45 $ 113,525 6.8 years Expected to vest 592 $ 156.11 $ 32,752 8.2 years Exercisable at April 30, 2021 788 $ 109.22 $ 80,514 5.8 years As of April 30, 2021, there was $12,291 of total unrecognized compensation cost related to unvested stock options. That cost is expected to be amortized over a weighted average period of approximately 1.7 years. The fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions: Six Months Ended April 30, 2021 April 30, 2020 Expected volatility 30.8% - 32.6% 24.5% - 29.2% Expected dividend yield 0.83% - 0.85% 0.92% - 1.16% Risk-free interest rate 0.43% - 0.77% 0.50% - 1.69% Expected life of the option (in years) 5.3 - 6.2 5.3 - 6.2 The weighted-average expected volatility used to value the 2021 and 2020 options was 31.0% and 25.1%, respectively. Historical information was the primary basis for the selection of the expected volatility, expected dividend yield and the expected lives of the options. The risk-free interest rate was selected based upon yields of U.S. Treasury issues with a term equal to the expected life of the option being valued. The weighted average grant date fair value of stock options granted during the six months ended April 30, 2021 and 2020 was $56.02 and $37.81, respectively. The total intrinsic value of options exercised during the three months ended April 30, 2021 and 2020 was $12,166 and $1,704, respectively. The total intrinsic value of options exercised during the six months ended April 30, 2021 and 2020 was $17,601 and $18,948, respectively. Cash received from the exercise of stock options for the six months ended April 30, 2021 and 2020 was $18,783 and $18,547, respectively. Restricted Shares and Restricted Share Units We may grant restricted shares and/or restricted share units to our employees and directors. These shares or units may not be transferred for a designated period of time (generally one For employee recipients, in the event of termination of employment due to early retirement with the consent of the Company, restricted shares and units granted within 12 months prior to termination are forfeited, and other restricted shares and units vest on a pro-rata basis, subject to the consent of the Compensation Committee. In the event of termination of employment due to normal retirement at age 65, restricted shares and units granted within 12 months prior to termination are forfeited, and, for other restricted shares and units, the restriction period applicable to restricted shares will lapse and the shares will vest and be transferable and all unvested units will become vested in full, subject to the consent of the Compensation Committee. In the event of a recipient's disability or death, all restricted shares and units granted within 12 months prior to termination fully vest. Termination for any other reason prior to the lapse of any restrictions or vesting of units results in forfeiture of the shares or units. For non-employee directors, all restrictions lapse in the event of disability or death of the non-employee director. Termination of service as a director for any other reason within one year of date of grant results in a pro-rata vesting of shares or units. As shares or units are issued, deferred stock-based compensation equivalent to the fair value on the date of grant is expensed over the vesting period. The following table summarizes activity related to restricted shares during the six months ended April 30, 2021: Number of Shares Weighted-Average Restricted shares at October 31, 2020 58 $ 148.75 Granted — — Forfeited (2) 149.37 Vested (28) 138.07 Restricted shares at April 30, 2021 28 $ 159.56 As of April 30, 2021, there was $2,655 of unrecognized compensation cost related to restricted shares. The cost is expected to be amortized over a weighted average period of 1.7 years. The amount charged to expense related to restricted shares during the three months ended April 30, 2021 and 2020 was $501 and $688, respectively, which included common share dividends of $13 and $18, respectively. For the six months ended April 30, 2021 and 2020, the amounts charged to expense related to restricted shares were $1,465 and $2,261, respectively, which included common share dividends of $31 and $43, respectively.

The amount charged to expense related to restricted share units during each of the three months ended April 30, 2021 and 2020 was $2,192 and $298, respectively, compared to $4,284 and $584 for the six months ended April 30, 2021 and 2020, respectively. Performance Share Incentive Awards Executive officers and selected other key employees are eligible to receive common share-based incentive awards. Payouts, in the form of unrestricted common shares, vary based on the degree to which corporate financial performance exceeds predetermined threshold, target and maximum performance goals over three-year performance periods. No payout will occur unless threshold performance is achieved. The amount of compensation expense is based upon current performance projections and the percentage of the requisite service that has been rendered. The calculations are based upon the grant date fair value which is principally driven by the stock price on the date of grant or a Monte Carlo valuation for awards granted in 2021. The per share values were $202.05 for 2021 and $201.50 for 2020. The amount credited to expense for the three months ended April 30, 2021 and 2020 was $460 and $3,703, respectively, compared to a charge of $4,295 and credit of $2,282 to expense for the six months ended April 30, 2021 and 2020, respectively. The cumulative amount recorded in shareholders’ equity at April 30, 2021 was $4,132. Deferred Compensation Our executive officers and other highly compensated employees may elect to defer up to 100% of their base pay and cash incentive compensation, and for executive officers, up to 90% of their share-based performance incentive payout each year. Additional share units are credited for quarterly dividends paid on our common shares. Expense related to dividends paid under this plan for the three months ended April 30, 2021 and 2020 was $29 and $83, respectively, compared to $58 and $164 for the six months ended April 30, 2021 and 2020, respectively. Deferred Directors’ Compensation Non-employee directors may defer all or part of their cash and equity-based compensation until retirement. Cash compensation may be deferred as cash or as share equivalent units. Deferred cash amounts are recorded as liabilities, and share equivalent units are recorded as equity. Additional share equivalent units are earned when common share dividends are declared. The following table summarizes activity related to director deferred compensation share equivalent units during the six months ended April 30, 2021: Number of Shares Weighted-Average Outstanding at October 31, 2020 120 $ 60.81 Dividend equivalents — — Distributions (11) 68.28 Outstanding at April 30, 2021 109 $ 60.86 The amount charged to expense related to director deferred compensation for the three months ended April 30, 2021 and 2020 was $63 and $42, respectively, compared to $125 and $86 for the six months ended April 30, 2021 and 2020, respectively.

Segment Reporting [Abstract]
Operating Segments	Operating segments We conduct business across two primary operating segments: Industrial Precision Solutions (IPS) and Advanced Technology Solutions (ATS). The composition of segments and measure of segment profitability is consistent with that used by our chief operating decision maker. The primary measure used by the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing performance is operating profit, which equals sales less cost of sales and certain operating expenses. Items below the operating profit line of the Condensed Consolidated Statements of Income (interest and investment income, interest expense and other income/expense) are excluded from the measure of segment profitability reviewed by our chief operating decision maker and are not presented by operating segment. Effective in the second quarter of 2020, we made changes to realign our management team and our operating segments, consolidating our former three operating segments into the two described above, which are reflected in our disclosures. Existing product lines were unchanged as part of this new structure. This realignment will enable us to better serve global customers and markets, to more efficiently leverage technology synergies, to operate divisions of significant size in a consistent and focused way and to position ourselves for our next chapter of profitable growth. The revised operating segments better reflect how we manage the Company, allocate resources, and assess performance of the businesses. Industrial Precision Solutions: This segment delivers proprietary dispensing and processing technology to diverse end markets. Product lines reduce material consumption, increase line efficiency and enhance product brand and appearance. Components are used for dispensing adhesives, coatings, paint, finishes, sealants and other materials. This segment primarily serves the non-durables, industrial and consumer durables markets. Advanced Technology Solutions: This segment integrates our proprietary product technologies found in progressive stages of a customer’s production processes, such as surface treatment, precisely controlled dispensing of material and post-dispense test and inspection to ensure quality. Related single-use plastic molded syringes, cartridges, tips, fluid connection components, tubing, balloons and catheters are used to dispense or control fluids in production processes or within customers’ end products. This segment predominantly serves customers in the electronics, medical and related high-tech industrial markets.

The following tables present the classification of our assets and liabilities measured at fair value on a recurring basis: April 30, 2021 Total Level 1 Level 2 Level 3 Assets: Foreign currency forward contracts (a) $ 1,255 $ — $ 1,255 $ — Total assets at fair value $ 1,255 $ — $ 1,255 $ — Liabilities: Deferred compensation plans (b) $ 12,118 $ — $ 12,118 $ — Foreign currency forward contracts (a) 3,283 — 3,283 — Total liabilities at fair value $ 15,401 $ — $ 15,401 $ — October 31, 2020 Total Level 1 Level 2 Level 3 Assets: Foreign currency forward contracts (a) $ 2,700 $ — $ 2,700 $ — Total assets at fair value $ 2,700 $ — $ 2,700 $ — Liabilities: Deferred compensation plans (b) $ 12,304 $ — $ 12,304 $ — Foreign currency forward contracts (a) 5,937 — 5,937 — Total liabilities at fair value $ 18,241 $ — $ 18,241 $ — (a) We enter into foreign currency forward contracts to reduce the risk of foreign currency exposures resulting from receivables, payables, intercompany receivables, intercompany payables and loans denominated in foreign currencies. Foreign exchange contracts are valued using market exchange rates. These foreign exchange contracts are not designated as hedges. (b) Executive officers and other highly compensated employees may defer up to 100 percent of their salary and annual cash incentive compensation and for executive officers, up to 90 percent of their long-term incentive compensation, into various non-qualified deferred compensation plans. Deferrals can be allocated to various market performance measurement funds. Changes in the value of compensation deferred under these plans are recognized each period based on the fair value of the underlying measurement funds. The carrying amounts and fair values of financial instruments, other than cash and cash equivalents, receivables, and accounts payable, are shown in the table below. The carrying values of cash and cash equivalents, receivables and accounts payable approximate fair value due to the short-term nature of these instruments. April 30, 2021 Carrying Fair Value Long-term debt (including current portion), excluding unamortized debt issuance costs $ 867,087 $ 921,834 We used the following methods and assumptions in estimating the fair value of financial instruments: • Long-term debt is valued by discounting future cash flows at currently available rates for borrowing arrangements with similar terms and conditions, which are considered to be Level 2 inputs under the fair value hierarchy.

Investments, All Other Investments [Abstract]
Derivative Financial Instruments	Derivative financial instruments We operate internationally and enter into intercompany transactions denominated in foreign currencies. Consequently, we are subject to market risk arising from exchange rate movements between the dates foreign currency transactions occur and the dates they are settled. We regularly use foreign currency forward contracts to reduce our risks related to most of these transactions. These contracts usually have maturities of 90 days or less and generally require us to exchange foreign currencies for U.S. dollars at maturity, at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in “Other – net” on the Condensed Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position. For the three months ended April 30, 2021, we recognized a net loss of $8,133 on foreign currency forward contracts and a realized net gain of $7,357 from the change in fair value of balance sheet positions. For the three months ended April 30, 2020, we recognized a net loss of $3,728 on foreign currency forward contracts and a net gain of $6,720 from the change in fair value of balance sheet positions. For the six months ended April 30, 2021, we recognized a net gain of $1,209 on foreign currency forward contracts and a realized net loss of $4,746 from the change in fair value of balance sheet positions. For the six months ended April 30, 2020, we recognized a net loss of $4,159 on foreign currency forward contracts and a net gain of $7,151 from the change in fair value of balance sheet positions. The following table summarizes, by currency, the foreign currency forward contracts outstanding at April 30, 2021 and 2020: Notional Amounts April 30, 2021 contract amounts: Sell Buy Euro $ 127,660 $ 309,020 British pound 21,228 79,446 Japanese yen 12,228 38,648 Australian dollar 194 10,240 Hong Kong dollar 978 33,024 Singapore dollar 15 18,071 Others 11,886 92,869 Total $ 174,189 $ 581,318 Notional Amounts April 30, 2020 contract amounts: Sell Buy Euro $ 110,114 $ 182,146 British pound 18,987 58,543 Japanese yen 16,301 31,934 Australian dollar 327 7,647 Hong Kong dollar 53,935 60,737 Singapore dollar 1,082 15,620 Others 3,995 61,286 Total $ 204,741 $ 417,913 We are exposed to credit-related losses in the event of nonperformance by counterparties to financial instruments. These financial instruments include cash deposits and foreign currency forward contracts. We periodically monitor the credit ratings of these counterparties in order to minimize our exposure. Our customers represent a wide variety of industries and geographic regions. For the three and six months ended April 30, 2021 and 2020, there were no significant concentrations of credit risk.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies We are involved in pending or potential litigation regarding environmental, product liability, patent, contract, employee and other matters arising from the normal course of business. Including the litigation and environmental matters discussed below, after consultation with legal counsel, we do not believe that losses in excess of the amounts we have accrued would have a material adverse effect on our financial condition, quarterly or annual operating results or cash flows. Class Action Litigation On February 22, 2019, a former employee, Mr. Ortiz, filed a purported class action lawsuit in the San Diego County Superior Court, California, against Nordson Asymtek, Inc. and Nordson Corporation, alleging various violations of the California Labor Code. Plaintiff seeks, among other things, an unspecified amount for unpaid wages, actual, consequential and incidental losses, penalties, and attorneys’ fees and costs . Following mediation in June 2020, the parties agreed to settle the lawsuit, subject to the execution of a written settlement agreement and court approval. If the settlement agreement is approved, the class action lawsuit will be resolved. Management believes, based on currently available information, that the ultimate outcome of the proceeding described above will not have a material adverse effect on the Company’s financial condition or results of operations. Environmental We have voluntarily agreed with the City of New Richmond, Wisconsin and other Potentially Responsible Parties to share costs associated with the remediation of the City of New Richmond municipal landfill (the “Site”) and the construction of a potable water delivery system serving the impacted area down gradient of the Site. At April 30, 2021 and October 31, 2020, our accrual for the ongoing operation, maintenance and monitoring obligation at the Site was $319 and $360, respectively. The liability for environmental remediation represents management’s best estimate of the probable and reasonably estimable undiscounted costs related to known remediation obligations. The accuracy of our estimate of environmental liability is affected by several uncertainties such as additional requirements that may be identified in connection with remedial activities, the complexity and evolution of environmental laws and regulations, and the identification of presently unknown remediation requirements. Consequently, our liability could be greater than our current estimate. However, we do not expect that the costs associated with remediation will have a material adverse effect on our financial condition or results of operations.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	6 Months Ended
	Apr. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation.  The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles in the United States (U.S. GAAP) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the full year. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended October 31, 2020.
Basis of Consolidation	Basis of consolidation.  The consolidated financial statements include the accounts of Nordson Corporation and its majority-owned and controlled subsidiaries. Investments in affiliates and joint ventures in which our ownership is 25% or less or in which we do not have control but have the ability to exercise significant influence, are accounted for under the cost method. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of estimates . The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Actual amounts could differ from these estimates.
Revenue Recognition	Revenue recognition . A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. Revenue is recognized when performance obligations under the terms of the contract with a customer are satisfied. Generally, our revenue results from short-term, fixed-price contracts and primarily is recognized as of a point in time when the product is shipped or at a later point when the control of the product transfers to the customer. Revenue for undelivered items is deferred and included within Accrued liabilities in our Condensed Consolidated Balance Sheets. Revenues deferred as of April 30, 2021 and 2020 were not material. However, for certain contracts related to the sale of customer-specific products within our Advanced Technology Solutions segment, revenue is recognized over time as we satisfy performance obligations because of the continuous transfer of control to the customer. The continuous transfer of control to the customer occurs as we enhance assets that are customer controlled and we are contractually entitled to payment for work performed to date plus a reasonable margin. As control transfers over time for these products or services, revenue is recognized based on progress toward completion of the performance obligations. The selection method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We have elected to use the input method – costs incurred for these contracts because it best depicts the transfer of products or services to the customer based on incurring costs on the contract. Under this method, revenues are recorded proportionally as costs are incurred. Contract assets recognized are recorded in Prepaid expenses and other current assets and contract liabilities are recorded in Accrued liabilities in our Condensed Consolidated Balance Sheets and were not material at April 30, 2021 and October 31, 2020. Revenue recognized over time is not material to our overall Consolidated Financial Statements. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services. Sales, value add, and other taxes we collect concurrently with revenue-producing activities are excluded from revenue. As a practical expedient, we may exclude the assessment of whether goods or services are performance obligations, if they are immaterial in the context of the contract, and combine these with other performance obligations. While payment terms and conditions vary by contract type, we have determined that our contracts generally do not include a significant financing component. We have elected to apply the practical expedient to treat all shipping and handling costs as fulfillment costs as a significant portion of these costs are incurred prior to transfer of control to the customer. We have also elected to apply the practical expedient to expense sales commissions as they are incurred as the amortization period resulting from capitalizing the costs is one year or less. These costs are recorded within Selling and administrative expenses in our Condensed Consolidated Statements of Income. We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term and is generally not material. Certain arrangements may include installation, installation supervision, training, and spare parts, which tend to be completed in a short period of time, at an insignificant cost, and utilizing skills not unique to us, and, therefore, are typically regarded as inconsequential or not material. We disclose disaggregated revenues by operating segment and geography in accordance with the revenue standard and on the same basis used internally by the chief operating decision maker for evaluating performance of operating segments and for allocating resources. Refer to our Operating Segments note.
Earnings Per Share	Earnings per share . Basic earnings per share are computed based on the weighted-average number of common shares outstanding during each year, while diluted earnings per share are based on the weighted-average number of common shares and common share equivalents outstanding. Common share equivalents consist of shares issuable upon exercise of stock options computed using the treasury stock method, as well as restricted shares and deferred stock-based compensation. Options with an exercise price higher than the average market price are excluded from the calculation of diluted earnings per share because the effect would be anti-dilutive. Options excluded from the calculation of diluted earnings per share for the three months ended April 30, 2021 and April 30, 2020 were 91 and 360, respectively. Options excluded from the calculation of diluted earnings per share for the six months ended April 30, 2021 and April 30, 2020 were 91 and 180, respectively.
New accounting guidance adopted	New accounting guidance adopted: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326),” which changed the impairment model for most financial instruments. Prior guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflected losses once the losses are probable. We adopted the new standard on November 1, 2020 and are now applying a current expected credit loss model that requires recognizing an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of the update, including trade receivables. The standard requires judgment and consideration of historical information, current information, and reasonable and supportable forecasts, as well as the impact of any prepayments. In addition, we reviewed our business processes and controls to support the recognition and disclosure as required under the new standard. The adoption of this new standard did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other Internal – Use Software (Subtopic 350-40),” which is meant to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement), by providing guidance in determining when the arrangement includes a software license. We adopted the new standard on November 1, 2020. Hosted arrangements deemed to be in scope will follow the capitalization criteria for implementation costs as though they were internal-use computer software. There may be multiple elements besides the software license (such as: training, future upgrades, data conversion, and other elements) which require the allocation of the contract price to each of the elements; entities are to capitalize only those elements which meet the capitalization criteria. Capitalized implementation costs are amortized over the term of the hosted arrangement including consideration for renewal or termination options. In addition, we reviewed our business processes and controls to support the recognition and disclosure as required under the new standard. The adoption of this new standard did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued a new standard which removed, modified, and added certain disclosure requirements on fair value measurements. The guidance removed disclosure requirements pertaining to the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. For investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly. In addition, the amendment clarified that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The guidance added disclosure requirements for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period as well as the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. We adopted the new standard on November 1, 2020 with no material impact to the Consolidated Financial Statements. New accounting guidance issued and not yet adopted: In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20),” a new standard which addresses defined benefit plans. The amendments modify the following disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans: the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, amount and timing of plan assets expected to be returned to the employer, related party disclosure about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, and the effects of a one-percentage point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligations for postretirement health care benefits. A disclosure requirement was added for the explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Additionally, the standard clarifies disclosure requirements surrounding the projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets and the accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. It will be effective for us beginning November 1, 2021. Early adoption is permitted. We are currently assessing the impact this standard will have on our Consolidated Financial Statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (ASC 740) – Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. It will be effective for us beginning November 1, 2021. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. We are currently assessing the impact this standard will have on our Consolidated Financial Statements.
