Environmental Taxes  
(Rev. January 2024)  
Section references are to the Internal Revenue Code unless  
otherwise noted.  
General Instructions  
Future Developments  
Purpose of Form  
For the latest information about developments related to Form  
6627 and its instructions, such as legislation enacted after they  
were published, go to IRS.gov/Form6627.  
Use this form to figure the environmental taxes on domestic  
crude oil and imported petroleum products, chemicals (other  
than ozone-depleting chemicals (ODCs)), imported chemical  
substances, ODCs, imported products that used ODCs as  
materials in the manufacture or production of the product, and  
the floor stocks tax on ODCs. If you need more lines for any part  
of the form, prepare a continuation sheet using the same format  
as the part. Attach the continuation sheet with Form 6627 to  
Form 720, Quarterly Federal Excise Tax Return. See Pub. 510,  
Excise Taxes, for more information on environmental taxes. See  
the Instructions for Form 720 for information on when and where  
to file Form 6627.  
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,  
21, and 53), later, and IRS.gov/irb/2023-48_IRB#NOT-2023-34.  
Who Must File  
For Petroleum  
1. The operator of the refinery that receives crude oil;  
2. The user of crude oil before tax is imposed; and  
The section 4681 tax rates for ozone-depleting chemicals  
(ODCs) are increased for 2024. See Part VI. Tax on Floor  
Stocks of ODCs, later.  
3. The person entering the petroleum products for  
consumption, use, or warehousing.

listing of taxable imported chemical substances and the  
IRS-provided tax rates for most of the substances. Any  
additional tax rates the IRS provides will be available either  
when they become available. Taxpayers are reminded that they  
may calculate their own tax rates for imported chemical  
substances, regardless of whether the IRS has provided a tax  
rate.  
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.  
See Notice 2022-15 for information about temporary relief  
from the penalty for failure to deposit the 2022 third and fourth  
quarter taxes.  
For updates, such as the not yet shown tax rates for taxable  
imported chemical substances, or substances recently added or  
removed, go to IRS.gov/Form6627. Also see frequently asked  
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

oil spill tax rate on IRS No. 21 and the petroleum Superfund tax  
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.

Part III. Tax on Imported Chemical Substances,  
IRS No. 17  
The imported chemical substance tax is equal to the chemical  
tax that would have been imposed on the taxable chemicals  
(listed in Part II of Form 6627) used as materials in the  
manufacture of the substance if such substance had been  
manufactured in the United States. See Table of Taxable  
Imported Chemical Substances for the substances to which the  
imported substance tax applies.

Tax per  
Pound in 2024  
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  
made, the tax on the post-1990 ODCs (listed earlier) contained  
chemical or the appraised entry value of the total amount of the

in the mixture is imposed on the date of sale or use of the  
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.
