	NOTE 1 — ORGANIZATION AND BUSINESS
	The United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP) (“UHN”) was organized as a limited partnership under the laws of the state of Delaware on April 13, 2007. UHN is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, UHN’s shares traded on the American Stock Exchange (the “AMEX”). UHN will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Second Amended and Restated Agreement of Limited Partnership, as amended March 1, 2013 (the “LP Agreement”). The investment objective of UHN is for the daily changes in daily percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the price of heating oil (also known as No. 2 fuel oil) for delivery to the New York harbor, as measured by the daily changes in the price of the futures contract for heating oil traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), less UHN’s expenses. It is not the intent of UHN to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of heating oil or any particular futures contract based on heating oil. It is not the intent of UHN to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. United States Commodity Funds LLC (“USCF”), the general partner of UHN, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts (as defined below) and Other Diesel-Heating Oil-Related Investments (as defined below). UHN accomplishes its objective through investments in futures contracts for heating oil, crude oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures Exchange (“ICE Futures”) or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and other diesel-heating oil-related investments such as cash-settled options on Futures Contracts, forward contracts for diesel-heating oil and over-the-counter transactions that are based on the price of diesel-heating oil, crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Diesel-Heating Oil-Related Investments”). As of September 30, 2014, UHN held 27 Futures Contracts for heating oil traded on the NYMEX and did not hold any Futures Contracts for heating oil on ICE Futures.
	UHN commenced investment operations on April 9, 2008 and has a fiscal year ending on December 31. USCF is responsible for the management of UHN. USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005 and a swaps firm on August 8, 2013. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”) and the United States Gasoline Fund, LP (“UGA”), which listed their limited partnership shares on the AMEX under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007 and “UGA” on February 26, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, USL’s and UGA’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“DNO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”), each a series of the United States Commodity Index Funds Trust. USCI, CPER, USAG and USMI listed their shares on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011, “USAG” on April 13, 2012 and “USMI” on June 19, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.”
	UHN issues shares to certain authorized purchasers (“Authorized Purchasers”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). The purchase price for a Creation Basket is based upon the NAV of a share calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received.
	The applicable transaction fee paid by Authorized Purchasers is $350 to UHN for each order they place to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”). Shares may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per share NAV of UHN but rather at market prices quoted on such exchange.
	In April 2008, UHN initially registered 10,000,000 shares on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On April 9, 2008, UHN listed its shares on the AMEX under the ticker symbol “UHN”. On that day, UHN established its initial per share NAV by setting the price at $50.00 and issued 200,000 shares in exchange for $10,000,000. UHN also commenced investment operations on April 9, 2008 by purchasing Futures Contracts traded on the NYMEX based on heating oil. As a result of the acquisition of the AMEX by NYSE Euronext, UHN commenced trading on the NYSE Arca on November 25, 2008. As of September 30, 2014, UHN had registered a total of 60,000,000 shares.
	The accompanying unaudited condensed financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X promulgated by the SEC and, therefore, do not include all information and footnote disclosure required under generally accepted accounting principles (“GAAP”) in the United States of America. The financial information included herein is unaudited; however, such financial information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of USCF, necessary for the fair presentation of the condensed financial statements for the interim period.

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Sep. 30, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification.  UHN is an investment company and follows the accounting and reporting guidance in FASB Topic 946.
	Revenue Recognition
	Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the condensed statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the condensed financial statements. Changes in the unrealized gains or losses between periods are reflected in the condensed statements of operations. UHN earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the overnight Federal Funds Rate, less 32 basis points. In addition, UHN earns income on funds held at the custodian or futures commission merchant at prevailing market rates earned on such investments.
	Brokerage Commissions
	Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
	Income Taxes
	UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.
	In accordance with GAAP, UHN is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2010. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in UHN recording a tax liability that reduces net assets. However, UHN’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. UHN recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the period ended September 30, 2014.
	Creations and Redemptions
	Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed.
	UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Purchasers are reflected in UHN’s condensed statements of financial condition as receivable for shares sold, and amounts payable to Authorized Purchasers upon redemption are reflected as payable for shares redeemed.
	Authorized Purchasers pay UHN a fee of $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.
	Partnership Capital and Allocation of Partnership Income and Losses
	Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.
	Calculation of Per Share Net Asset Value
	UHN’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
	Net Income (Loss) Per Share
	Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were no shares held by USCF at September 30, 2014.
	Offering Costs
	Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.
	Cash Equivalents
	Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of nine months or less.
	Reclassification
	Certain amounts in the accompanying condensed financial statements were reclassified to conform to the current presentation.
	Use of Estimates
	The preparation of condensed financial statements in conformity with GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.

	NOTE 3 — FEES PAID BY THE FUND AND RELATED PARTY TRANSACTIONS
	USCF Management Fee
	Under the LP Agreement, USCF is responsible for investing the assets of UHN in accordance with the objectives and policies of UHN. In addition, USCF has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to UHN. For these services, UHN is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.60% per annum of average daily total net assets.
	Ongoing Registration Fees and Other Offering Expenses
	UHN pays all costs and expenses associated with the ongoing registration of its shares subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of shares, and all legal, accounting, printing and other expenses associated with such offer and sale. For the nine months ended September 30, 2014 and 2013, UHN incurred $5,460 and $5,460, respectively, in registration fees and other offering expenses.
	Directors’ Fees and Expenses
	UHN is responsible for paying its portion of the directors’ and officers’ liability insurance for UHN and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of UHN and the Related Public Funds. UHN shares the fees and expenses on a pro rata basis with each Related Public Fund, as described above, based on the relative assets of each Related Public Fund computed on a daily basis. These fees and expenses for the year ending December 31, 2014 are estimated to be a total of $560,625 for UHN and the Related Public Funds.
	Licensing Fees
	As discussed in Note 4 below, UHN entered into a licensing agreement with the NYMEX on April 10, 2006, as amended on October 20, 2011. Pursuant to the agreement, UHN and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, pay a licensing fee that is equal to 0.015% on all net assets. During the nine months ended September 30, 2014 and 2013, UHN incurred $469 and $ 737, respectively, under this arrangement.
	Investor Tax Reporting Cost
	The fees and expenses associated with UHN’s audit expenses and tax accounting and reporting requirements are paid by UHN. These costs are estimated to be $65,000 for the year ending December 31, 2014.
	Other Expenses and Fees and Expense Waivers
	In addition to the fees described above, UHN pays all brokerage fees and other expenses in connection with the operation of UHN, excluding costs and expenses paid by USCF as outlined in Note 4 below. USCF has voluntarily agreed to pay certain expenses normally borne by UHN to the extent that such expenses exceed 0.15% (15 basis points) of UHN’s NAV, on an annualized basis, through at least December 31, 2014. USCF has no obligation to continue such payments into subsequent periods. For the nine months ended September 30, 2014, USCF waived $92,807 of UHN’s expenses. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 4.

	On October 8, 2013, UHN entered into a brokerage agreement with RBC Capital Markets, LLC (“RBC Capital” or “RBC”) to serve as UHN’s futures commission merchant (“FCM”), effective October 10, 2013. Prior to October 10, 2013, the FCM was UBS Securities LLC (“UBS Securities”).  The agreements require RBC Capital and UBS Securities to provide services to UHN in connection with the purchase and sale of Futures Contracts and Other Diesel-Heating Oil-Related Investments that may be purchased and sold by or through RBC Capital and/or UBS Securities for UHN’s account. In accordance with each agreement, RBC Capital and UBS Securities charge UHN commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Futures Contracts and options on Futures Contracts.

	The decrease in the total commissions accrued to brokers for the nine months ended September 30, 2014, compared to the nine months ended September 30, 2013, was a result of decreased brokerage fees due to a lower number of futures contracts being held and traded. As an annualized percentage of average daily total net assets, the figure for the nine months ended September 30, 2014, represents approximately 0.06% of average daily total net assets. By comparison, the figure for the nine months ended September 30, 2013, represented approximately 0.06% of average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.
	UHN and the NYMEX entered into a licensing agreement on May 30, 2007, as amended on October 20, 2011, whereby UHN was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, UHN and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. UHN expressly disclaims any association with the NYMEX or endorsement of UHN by the NYMEX and acknowledges that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of the NYMEX.

Financial Instruments Off Balance Sheet Risks and Contingencies [Abstract]	'
Financial Instruments, Off-Balance Sheet Risks and Contingencies	'
	NOTE 5 — FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES
	UHN engages in the trading of futures contracts and options on futures contracts (collectively, “derivatives”). UHN is exposed to both market risk, which is the risk arising from changes in the market value of the contracts, and credit risk, which is the risk of failure by another party to perform according to the terms of a contract.
	UHN may enter into futures contracts and options on futures contracts to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are over-the-counter agreements that are eligible to be cleared by a clearinghouse, e.g., ICE Clear Europe, but which are not traded on an exchange. A cleared swap is created when the parties to an off-exchange over-the-counter swap transaction agree to extinguish their over-the-counter contract and replace it with a cleared swap. Cleared swaps are intended to provide the efficiencies and benefits that centralized clearing on an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties.
	The purchase and sale of futures contracts and options on futures contracts require margin deposits with a futures commission merchant. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a futures commission merchant to segregate all customer transactions and assets from the futures commission merchant’s proprietary activities.
	Futures contracts, options on futures contracts and cleared swaps involve, to varying degrees, elements of market risk (specifically commodity price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure UHN has in the particular classes of instruments. Additional risks associated with the use of futures contracts are an imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts.
	All of the futures contracts held by UHN were exchange-traded through September 30, 2014. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if UHN were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. UHN has credit risk under its futures contracts since the sole counterparty to all domestic and foreign futures contracts is the clearinghouse for the exchange on which the relevant contracts are traded. In addition, UHN bears the risk of financial failure by the clearing broker.
	UHN’s cash and other property, such as Treasuries, deposited with a futures commission merchant are considered commingled with all other customer funds, subject to the futures commission merchant’s segregation requirements. In the event of a futures commission merchant’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The insolvency of a futures commission merchant could result in the complete loss of UHN’s assets posted with that futures commission merchant; however, the majority of UHN’s assets are held in Treasuries, cash and/or cash equivalents with UHN’s custodian and would not be impacted by the insolvency of a futures commission merchant. The failure or insolvency of UHN’s custodian however, could result in a substantial loss of UHN’s assets.
	USCF invests a portion of UHN’s cash in money market funds that seek to maintain a stable per share NAV. UHN is exposed to any risk of loss associated with an investment in such money market funds. As of September 30, 2014 and December 31, 2013, UHN held investments in money market funds in the amounts of $1,802,006 and $3,202,094, respectively. UHN also holds cash deposits with its custodian. Pursuant to a written agreement with BBH&Co., uninvested overnight cash balances are swept to offshore branches of U.S. regulated and domiciled banks located in Toronto, Canada; London, United Kingdom; Grand Cayman, Cayman Islands; and Nassau, Bahamas; which are subject to U.S. regulation and regulatory oversight. As of September 30, 2014 and December 31, 2013, UHN held cash deposits and investments in Treasuries in the amounts of $1,076,030 and $1,396,239, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should UHN’s custodian and/or futures commission merchant cease operations.
	For derivatives, risks arise from changes in the market value of the contracts. Theoretically, UHN is exposed to market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. As both a buyer and a seller of options, UHN pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option.
	UHN’s policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting controls and procedures. In addition, UHN has a policy of requiring review of the credit standing of each counterparty with which it conducts business. The financial instruments held by UHN are reported in its condensed statements of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

NOTE 7 — FAIR VALUE OF FINANCIAL INSTRUMENTS

UHN values its investments in accordance with Accounting Standards Codification 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The changes to past practice resulting from the application of ASC 820 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurement. ASC 820 establishes a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of UHN (observable inputs) and (2) UHN’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the ASC 820 hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety.

The following table summarizes the valuation of UHN’s securities at September 30, 2014 using the fair value hierarchy:

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification.  UHN is an investment company and follows the accounting and reporting guidance in FASB Topic 946.
Revenue Recognition	'
	Revenue Recognition
	Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the condensed statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the condensed financial statements. Changes in the unrealized gains or losses between periods are reflected in the condensed statements of operations. UHN earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the overnight Federal Funds Rate, less 32 basis points. In addition, UHN earns income on funds held at the custodian or futures commission merchant at prevailing market rates earned on such investments.
Brokerage Commissions	'
	Brokerage Commissions
	Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
Income Taxes	'
	Income Taxes
	UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.
	In accordance with GAAP, UHN is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2010. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in UHN recording a tax liability that reduces net assets. However, UHN’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. UHN recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the period ended September 30, 2014.
Creations and Redemptions	'
	Creations and Redemptions
	Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed.
	UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Purchasers are reflected in UHN’s condensed statements of financial condition as receivable for shares sold, and amounts payable to Authorized Purchasers upon redemption are reflected as payable for shares redeemed.
	Authorized Purchasers pay UHN a fee of $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.
Partnership Capital and Allocation of Partnership Income and Losses	'
	Partnership Capital and Allocation of Partnership Income and Losses
	Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.
Calculation of Per Unit Net Asset Value	'
	Calculation of Per Share Net Asset Value
	UHN’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
Net Income (Loss) Per Share	'
	Net Income (Loss) Per Share
	Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were no shares held by USCF at September 30, 2014.
Offering Costs	'
	Offering Costs
	Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.
Cash Equivalents	'
	Cash Equivalents
	Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of nine months or less.
Reclassification	'
	Reclassification
	Certain amounts in the accompanying condensed financial statements were reclassified to conform to the current presentation.
Use of Estimates	'
	Use of Estimates
	The preparation of condensed financial statements in conformity with GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.
