What’s New
The Inflation Reduction Act of 2022 reinstated the section 4611
Hazardous Substance Superfund financing rate (petroleum
Superfund tax rate) on domestic crude oil and imported
petroleum products, effective January 1, 2023, and stated that
the tax will be indexed for inflation beginning in 2024. The
financing rate is actually two taxes: the Hazardous Substance
Superfund rate that's annually adjusted for inflation, on lines 3a,
4a, and 7; and the $.09 per barrel Oil Spill Liability Trust Fund
financing rate on lines 3b, 4b, and 8. For 2024, the Hazardous
Substance Superfund rate is adjusted for inflation and increased
to $.17 per barrel. See Part I. Tax on Petroleum (IRS Nos. 16, 18,
Who Must File

Specific Instructions
Part I. Tax on Petroleum (IRS Nos. 16, 18, 21,
and 53)
The tax rate on domestic crude oil and imported petroleum
products is the sum of the Oil Spill Liability Trust Fund financing
rate (petroleum oil spill tax rate) and the Hazardous Substance
Superfund financing rate (petroleum Superfund tax rate). The
petroleum oil spill tax rate is $0.09 per barrel. For 2024, the
petroleum Superfund tax rate is $.17 per barrel (this rate will be
indexed annually for inflation).
Rev. Proc. 2022-26 provides procedures for requesting a

determination that a substance be added or removed.
•
from the penalty for failure to deposit the 2022 third and fourth
quarter taxes.

Although the domestic crude oil or imported petroleum
products are reported separately, there is no difference in tax
rates. For domestic crude oil, report the petroleum oil spill tax
rate on IRS No. 18 and the petroleum Superfund tax rate on IRS
No. 53. For imported petroleum products, report the petroleum

rate on IRS No. 16.
substance. If using an IRS-provided tax rate, there’s no need to
enter information in column (d).
Crude oil. Tax is imposed on domestic crude oil when it is
received at a U.S. refinery. Crude oil includes crude oil
condensates and natural gasoline. The operator of the refinery is
liable for the tax. Tax is imposed on imported crude oil received
at a U.S. refinery unless the imported petroleum products tax
was imposed when the imported crude oil was entered into the
United States. The operator of a U.S. refinery that receives
imported crude oil must establish that tax was previously
imposed on the imported crude oil.
Column (e). Enter the tax rate of each taxable chemical from
Part II of Form 6627. If you don’t have enough information to
determine the conversion factor and are using an IRS-provided
tax rate, enter that tax rate here. If you don’t have enough
information to determine the conversion factor and you’re figuring
the tax based on the appraised entry value, enter 10% here.
Column (f). Multiply the number of tons in column (b) by the
conversion factor in column (d) by the rate in column (e) for each
taxable chemical listed. If you don’t have enough information to
determine the conversion factor and the IRS has provided a tax
rate, multiply column (b) by column (e). If you don’t have enough
information to determine the conversion factor and the IRS
hasn’t provided a tax rate, you must use the appraised entry
value to figure the tax. To figure the tax using the appraised entry
value, multiply the appraised entry value in column (d) by the
rate (10%) in column (e).
User of crude oil. Tax is imposed on domestic crude oil that’s
used before it is received at a U.S. refinery. The user is liable for
the tax. Crude oil used for extracting oil or natural gas on the
premises where the crude oil is produced is not taxable.
Imported petroleum products. Tax is imposed on imported
petroleum products when they are entered into the United States
for use, consumption, or warehousing. Petroleum products
include crude oil, refined and residual oil, and other liquid
hydrocarbon refinery products. The person entering the
petroleum product into the country is liable for the tax.
The tax on petroleum is imposed only once on any imported
petroleum product. The enterer must provide documentation of
the tax imposed on imported crude oil to the refinery operator if
requested by the refinery operator.
Part IV. Tax on Ozone-Depleting Chemicals
(ODCs), IRS No. 98
The following ODCs are taxable.
Fractional barrels. Fractional barrels are taxed at a
Post-1989 ODCs
Tax per
proportionate rate using the fraction produced by the number of
gallons in the barrel over 42 gallons. Multiply the resulting
fraction by the sum of the $0.09 per barrel petroleum oil spill tax
rate and the $.17 per barrel petroleum Superfund tax rate.

To figure the tax, you’ll generally need to know the ratio of the
weight of each taxable chemical used to make the substance to
the total weight of the substance (the conversion factor). If you
don’t have enough information to determine the conversion
factor and the IRS has provided a tax rate for the substance,

Substances, then that tax rate applies. If you don’t have enough
information to determine the conversion factor and the IRS
hasn’t provided a tax rate for the substance, then the tax is 10%
of the appraised entry value of the substance.
The tax per pound rates above are figured using the
ozone-depletion factor. Do not multiply the tax per pound
by the ozone-depletion factor.
!
CAUTION
Follow the steps, next, to figure the tax for Part III, lines 1
through 3.
Mixture elections. Generally, the creation of a mixture
containing one or more ODCs by the manufacturer or importer of
an ODC is treated as the use of the ODC in the mixture.
However, the manufacturer or importer may elect to treat the sale
or use of the mixture as the first sale or use of the ODC in the
mixture.
Column (a). Enter the imported chemical substance subject to
tax.
Column (b). Enter the number of tons of the substance
imported and sold or used.
Column (c). Enter each taxable chemical (listed in Part II of
Form 6627) used in the manufacture of the substance. If using
an IRS-provided tax rate or a tax rate based on 10% of the
appraised entry value of the substance, there’s no need to enter
information in column (c).
Post-1989 ODCs (the 1990 election). If this election is
made, the tax on the post-1989 ODCs (listed earlier) contained
in the mixture is imposed on the date of sale or use of the
mixture. To make the election, check the first box in Part IV,
under Elections. This election may be revoked only with the
consent of the IRS.
Column (d). Enter the conversion factor for each taxable
Post-1990 ODCs (the 1991 election). If this election is

mixture. To make the election, check the second box in Part IV,
under Elections. This election may be revoked only with the
consent of the IRS.
Column (e). If you are using the value method to figure the tax,
enter the entry value of the total number of imported products.
Column (f). Figure the tax due by multiplying the number of
products in column (b) by the ODC weight in column (c) by the
tax per pound in column (d). If you are using the value method,
multiply the 1% (0.01) rate in column (d) by the entry value in
column (e).
Column (c). Enter the tax per pound using the chart earlier.
Part V. ODC Tax on Imported Products, IRS No.
19
Part VI. Tax on Floor Stocks of ODCs
An imported taxable product is any product entered into the
United States for consumption, use, or warehousing if any ODC
was used as material in the manufacture or production of the
product. The product must also be listed in the imported
products table issued by the IRS. See Regulations section
52.4682-3(f)(6). The tax is based on the weight of ODCs used in
the manufacture of the product. If the weight can’t be determined
under the exact method or table method (see below), the tax is
1% of the entry value of the product (value method).
The floor stocks tax for 2024 is imposed on the following ODCs.

Importer election. Generally, an imported taxable product is
taxed when sold or used by the importer. However, an importer
may elect to treat the entry of products into the United States as
the use of such products. This election applies to all products
held by the importer when the election becomes effective, and all
products the importer enters into the United States after the
election becomes effective. If an election applies to an imported
taxable product, tax is imposed on the product on the date of
entry. To make the election, check the box in Part V, under
Elections. This election may be revoked only with the consent of
the IRS.
