Sec. 52.4682-4  Floor stocks tax.

    (a) Overview. This section provides rules for identifying ozone-
depleting chemicals (ODCs) that are subject to the floor stocks tax 
imposed by section 4682(h)(1), determining the person that is liable for 
the tax, and computing the amount of the tax. See Sec. 52.4681-1(a)(3) 
and (c) for general rules and definitions relating to the floor stocks 
tax.
    (b) Identifying rules--(1) ODCs subject to floor stocks tax; ODCs 
held for sale or for use in further manufacture--(i) In general. The 
floor stocks tax is imposed only on an ODC that is held for sale or for 
use in further manufacture on the date the tax is imposed. This 
paragraph (b)(1) provides rules for identifying ODCs held for sale or 
for use in further manufacture.
    (ii) Held for sale--(A) In general. For purposes of determining 
whether an ODC is held for sale, the term sale shall have the meaning 
set forth in Sec. 52.4681-1(c)(6). ODCs held for sale include ODCs that 
will be sold in connection with the provision of services or in 
connection with the sale of a manufactured article and, in such cases, 
include ODCs that will be sold without the statement of a separate 
charge for those ODCs.
    (B) ODCs held by a government. An ODC that is held by a government 
for its own use is not held for sale even if the ODC will be transferred 
between agencies or other subdivisions that have or are required to have 
different employer identification numbers.
    (iii) Held for use in further manufacture. Except as otherwise 
provided in paragraph (b)(2)(v) of this section, an ODC is held for use 
in further manufacture if--
    (A) The ODC will be used as a material (within the meaning of 
paragraph (b)(1)(iv) of this section) in the manufacture of an article; 
and
    (B) Such article will be held for sale.
    (iv) Use as material--(A) In general. Except as provided in 
paragraph (b)(1)(iv)(B) of this section, an ODC will be used as a 
material in the manufacture of an article if the ODC will be--
    (1) Incorporated into the article; or
    (2) Released into the atmosphere in the process of manufacturing the 
article.
    (B) ODCs used in equipment. For purposes of the floor stocks tax, an 
ODC is not used as a material in the manufacture of an article if the 
ODC is (or will be) contained in equipment used in such manufacture and 
the ODC will be used for its intended purpose without being released 
from such equipment. Thus, ODCs that are (or will be) used as coolants 
in a factory's air-conditioning system are not used as materials in the 
manufacture of articles produced in the factory.
    (v) Storage containers. The floor stocks tax is imposed on an ODC 
without regard to the type or size of the

[[Page 32]]

storage container in which the ODC is held. Thus, the tax may apply to 
an ODC whether it is in a 14-ounce can or a 30-pound tank.
    (vi) Examples. The provisions of this paragraph (b)(1) may be 
illustrated by the following examples:

    Example 1. A, a manufacturer of air conditioners, holds an ODC for 
use in air conditioners that it will manufacture and sell. A holds the 
ODC for use in further manufacture.
    Example 2. B, a manufacturer of electronic components, holds an ODC 
for use as a solvent to clean printed circuits that it will sell to 
computer manufacturers. B holds the ODC for use in further manufacture.
    Example 3. C, an automobile dealer, holds an ODC for use in charging 
air conditioners installed in automobiles that it sells to retail 
customers. C does not hold the ODC for use in further manufacture. C 
does, however, hold the ODC for sale, even if the customers are not 
separately charged for ODCs used in the automobile air conditioners.
    Example 4. D operates an air-conditioning repair service and holds 
an ODC for use in repairing air conditioners for its customers. D holds 
the ODC for sale even if the customers are not separately charged for 
ODCs used in the repairs.
    Example 5. E, a grocery-store chain, holds an ODC for use in its 
refrigeration units. E does not hold the ODC for sale or for use in 
further manufacture.
    Example 6. F, a bank, holds an ODC for use in its fire extinguishers 
to protect the computer system. F does not hold the ODC for sale or for 
use in further manufacture.
    Example 7. G, a government agency, holds an ODC for use in the 
refrigeration equipment of its various units. The units have separate 
employer identification numbers. The ODC is stored in a central 
warehouse until needed by a unit and then transferred to the unit upon 
request. G does not hold the ODC for sale or for use in further 
manufacture.

    (2)(i) Mixtures--(A) Tax imposed on January 1, 1990. In the case of 
the floor stocks tax imposed on January l, 1990, the tax is not imposed 
on an ODC that has been mixed with any other ingredients.
    (B) Taxes imposed after 1990--(1) In general. In the case of the 
floor stocks tax imposed on January 1 of a calendar year after 1990, the 
tax is not imposed on an ODC that has been mixed with any other 
ingredients, but only if it is established that such ingredients 
contribute to the accomplishment of the purpose for which the mixture 
will be used. A mixture is not exempt from tax under this paragraph 
(b)(2)(i)(B), however, if it contains only an ODC and an inert 
ingredient that does not contribute to the accomplishment of the purpose 
for which the mixture will be used.
    (2) Exception. In the case of a floor stocks tax imposed on or after 
January 1, 1992, a mixture is not exempt from floor stocks tax under 
this paragraph (b)(2)(i)(B) if it contains only ODCs and one or more 
stabilizers. For this purpose, the term stabilizer means an ingredient 
needed to maintain the chemical integrity of the ODC.
    (C) Examples. The provisions of this paragraph (b)(2)(i) may be 
illustrated by the following examples:

    Example 1. The floor stocks tax is not imposed on the ODCs contained 
in refrigerants such as R-500 and R-502 because such products are 
mixtures of ODCs and other chemicals that contribute to the 
accomplishment of the purpose for which the mixture will be used.
    Example 2. The floor stocks tax is not imposed on the ODCs contained 
in automotive products used for checking for leaks because such products 
are a mixture of ODCs and small amounts of dyes and oils that contribute 
to the accomplishment of the purpose for which the mixture will be used.
    Example 3. The floor stocks tax is not imposed on Halon 1301 
pressurized with nitrogen. Although nitrogen is an inert ingredient, it 
contributes to the accomplishment of the purpose for which the mixture 
will be used.
    Example 4. On January 1, 1993, the floor stocks tax is imposed on 
methyl chloroform that is stabilized to prevent hydrolization or 
chemical reaction during transportation or use, unless the stabilized 
methyl chloroform has also been mixed with other ingredients that 
contribute to the accomplishment of the purpose for which the mixture 
will be used.

    (ii) Manufactured articles. The floor stocks tax is not imposed on 
an ODC that is contained in a manufactured article in which the ODC will 
be used for its intended purpose without being released from such 
article. For example, the tax is not imposed on the ODCs contained in 
the cooling coils of a refrigerator even if the refrigerator is held for 
sale. However, the tax is imposed on a can of ODC used to recharge an 
air conditioning unit because the ODC must be expelled from the can in

[[Page 33]]

order to be used. Similarly, beginning in 1991, the tax is imposed on 
Halons contained in a fire extinguisher held for sale because such ODCs 
must be expelled from the fire extinguisher in order to be used.
    (iii) Recycled ODCs. The floor stocks tax is not imposed on ODCs 
that have been reclaimed or recycled. For example, the tax is not 
imposed on an ODC that is held for use in further manufacture after 
being used as a solvent and recycled.
    (iv) ODCs held by the manufacturer or importer. The floor stocks tax 
is not imposed on ODCs held by their manufacturer or importer.
    (v) ODCs used as a feedstock--(A) In general. The floor stocks tax 
is not imposed on any ODC that was sold in a qualifying sale for use as 
a feedstock (as defined in Sec. 52.4682-1(c)).
    (B) Post-1989 ODCs sold before January 1, 1990; post-1990 ODCs sold 
before January 1, 1991. A post-1989 ODC that was sold by its 
manufacturer or importer before January 1, 1990, or a post-1990 ODC that 
was sold by its manufacturer or importer before January 1, 1991, shall 
be treated, for purposes of this paragraph (b)(2)(v), as an ODC that was 
sold in a qualifying sale for purposes of Sec. 52.4682-1(c) if the ODC 
will be used as a feedstock (within the meaning of Sec. 52.4682-
2(c)(3)).
    (vi) ODCs to be exported--(A) In general. The floor stocks tax is 
not imposed on any ODC that was sold in a qualifying sale for export (as 
defined in Sec. 52.4682-5(d)(1)).
    (B) ODCs sold before January 1, 1993. An ODC that was sold by its 
manufacturer or importer before January 1, 1993, is treated, for 
purposes of this paragraph (b)(2)(vi), as an ODC that was sold in a 
qualifying sale for export for purposes of Sec. 52.4682-5(d)(1) if the 
ODC will be exported.
    (vii) ODCs used as propellants in metered-dose inhalers; years after 
1992--(A) In general. The floor stocks tax is not imposed on January 1 
of calendar years after 1992 on any ODC that was sold in a qualifying 
sale for use as a propellant in a metered-dose inhaler (as defined in 
Sec. 52.4682-1(h)).
    (B) ODCs sold before January 1, 1993. An ODC that was sold by its 
manufacturer or importer before January 1, 1993, is treated, for 
purposes of this paragraph (b)(2)(vii), as an ODC that was sold in a 
qualifying sale for purposes of Sec. 52.4682-1(h) if the ODC will be 
used as a propellant in a metered-dose inhaler (within the meaning of 
Sec. 52.4682-1(h)).
    (viii) ODCs used as medical sterilants; 1993. The floor stocks tax 
is not imposed in 1993 on any ODC held for use as a medical sterilant 
(as defined in Sec. 52.4682-1(g)).
    (c) Person liable for tax--(1) In general. The person liable for the 
floor stocks tax on an ODC is the person that holds the ODC on a date on 
which the tax is imposed. The person who holds the ODC is the person who 
has title to the ODC (whether or not delivery to such person has been 
made) as of the first moment of such date. The person who has title at 
such time is determined under applicable local law.
    (2) Special rule. Each business unit that has, or is required to 
have, its own employer identification number is treated as a separate 
person for purposes of the floor stocks tax. For example, a chain of 
automotive parts stores that has one employer identification number is 
one person for purposes of the floor stocks tax, and a parent 
corporation and subsidiary corporation that each have a different 
employer identification number are two persons for purposes of the floor 
stocks tax.
    (d) Computation of tax; tentative tax amount--(1) In general--(i) 
Generally applicable rules. This paragraph (d) provides rules for 
determining the tentative tax amount and the amount of the floor stocks 
tax. Section 52.4681-1(a)(3) provides that the amount of the floor 
stocks tax on an ODC is determined by reference to a tentative tax 
amount. The tentative tax amount is the amount of tax that would be 
imposed on the ODC under section 4681(a)(1) if a sale of the ODC by the 
manufacturer or importer had occurred on the date the floor stocks tax 
is imposed. The amount of the floor stocks tax imposed on the ODCs 
contained in a nonexempt mixture is computed on the basis of the weight 
of the ODCs in that mixture.
    (ii) Floor stocks tax imposed on post-1989 ODCs on January 1, 1990. 
The floor stocks tax imposed on post-1989 ODCs

[[Page 34]]

(as defined in Sec. 52.4681-1(c)(9)) on January 1, 1990, is equal to 
the tentative tax amount. See paragraph (d)(2) of this section for rules 
relating to the floor stocks tax imposed on ODCs used in the manufacture 
of rigid foam insulation. See paragraph (d)(3) of this section for rules 
relating to the floor stocks tax imposed on Halons.
    (iii) Floor stocks tax imposed on post-1990 ODCs on January 1, 1991. 
The floor stocks tax imposed on post-1990 ODCs (as defined in Sec. 
52.4681-1(c)(9)) on January 1, 1991, is equal to the tentative tax 
amount.
    (iv) Other floor stocks taxes--(A) In general. The following rules 
apply for floor stocks taxes imposed on post-1989 ODCs after January 1, 
1990, and on post-1990 ODCs after January 1, 1991:
    (1) The tentative tax amount is determined, except as provided in 
paragraph (d)(2), (3), or (4) of this section, by reference to the rate 
of tax prescribed in section 4681(b)(1)(B) and the ozone-depletion 
factors prescribed in section 4682(b).
    (2) The amount of the floor stocks tax on an ODC is equal to the 
amount by which the tentative tax amount exceeds the amount of taxes 
previously imposed on the ODC.
    (B) Example. The application of this paragraph (d)(1)(iv) may be 
illustrated by the following example:

    Example. The floor stocks tax imposed on one pound of CFC-12 held 
for sale on January 1, 1992, is $0.30 (the amount by which $1.67, the 
tentative tax, exceeds $1.37, the tax previously imposed on CFC-12).

    (2) ODCs used in the manufacture of rigid foam insulation; 1990, 
1991, 1992, and 1993--(i) In general. In the case of an ODC that was 
sold in a qualifying sale for purposes of Sec. 52.4682-1(d) (relating 
to use in the manufacture of rigid foam insulation) the tentative tax 
amount is determined under section 4682(g) for purposes of computing the 
floor stocks tax imposed on the ODC on January 1, 1990, 1991, 1992 or 
1993. For purposes of computing the floor stocks tax imposed on the ODC 
on January 1, 1990, the tentative tax amount is zero. The floor stocks 
tax is not imposed on ODCs for use in the manufacture of rigid foam 
insulation in 1992 and 1993.
    (ii) Post-1989 ODCs sold before January 1, 1990; post-1990 ODCs sold 
before January 1, 1991. A post-1989 ODC that was sold by its 
manufacturer or importer before January 1, 1990, or a post-1990 ODC that 
was sold by its manufacturer or importer before January 1, 1991, shall 
be treated, for purposes of paragraphs (d)(2) and (e) of this section, 
as an ODC that was sold in a qualifying sale for purposes of Sec. 
52.4682-1(d) if the ODC wi11 be used in the manufacture of rigid foam 
insulation (within the meaning of Sec. Sec. 52.4682-1(d) (3) and (4)).
    (3) Halons; 1990, 1991, 1992, and 1993. In the case of Halon-1211, 
Halon-1301, or Halon-2402 (Halons), the tentative tax amount is 
determined under section 4682(g) for purposes of computing the floor 
stocks tax imposed on Halons on January 1, 1990, 1991, 1992, or 1993. 
For purposes of computing the floor stocks tax imposed on Halons on 
January 1, 1990, the tentative tax amount is zero. The floor stocks tax 
is not imposed on Halons in 1992 and 1993.
    (4) Methyl chloroform; 1993. In the case of methyl chloroform, the 
tentative tax amount is determined under section 4682(g)(5) for purposes 
of computing the floor stocks tax imposed on January 1, 1993.
    (e) De minimis exception--(1) 1990 and 1992. In the case of the 
floor stocks tax imposed on January 1, 1990 or 1992, a person is liable 
for the tax only if, on the date the tax is imposed, the person holds at 
least 400 pounds of post-1989 ODCs that are not described in paragraph 
(d) (2) or (3) of this section and are otherwise subject to tax.
    (2) 1991. In the case of the floor stocks tax imposed on January 1, 
1991, a person is liable for the tax only if, on such date, the person 
holds at least 400 pounds of ODCs subject to the 1991 floor stocks tax. 
For this purpose, ODCs subject to the 1991 floor stocks tax are--
    (i) Post-1990 ODCs that are subject to tax; and
    (ii) Post-1989 ODCs that are described in paragraph (d) (2) or (3) 
of this section and are otherwise subject to tax.
    (3) 1993. In the case of the floor stocks tax imposed on January 1, 
1993, a person is liable for the tax only if, on such date, the person 
holds at least 400 pounds of ODCs that are not described in paragraph 
(d) (2) or (3) of this section and are otherwise subject to tax.

[[Page 35]]

    (4) 1994. In the case of the floor stocks tax imposed on January 1, 
1994, a person is liable for the tax only if, on such date, the person 
holds--
    (i) At least 400 pounds of ODCs that are not described in paragraph 
(d)(2) or (d)(3) of this section and are otherwise subject to tax;
    (ii) At least 200 pounds of ODCs that are described in paragraph 
(d)(2) of this section and are otherwise subject to tax; or
    (iii) At least 20 pounds of ODCs that are described in paragraph 
(d)(3) of this section and are otherwise subject to tax.
    (5) Calendar years after 1994. In the case of the floor stocks tax 
imposed on January 1 of 1995 and each following calendar year, a person 
is liable for the tax only if, on such date, the person holds--
    (i) At least 400 pounds of ODCs that are not described in paragraph 
(d)(3) or (d)(4) of this section and are otherwise subject to tax;
    (ii) At least 50 pounds of ODCs that are described in paragraph 
(d)(3) of this section and are otherwise subject to tax; or
    (iii) At least 1000 pounds of ODCs that are described in paragraph 
(d)(4) of this section and are otherwise subject to tax.
    (6) Examples. The rules of this paragraph (e) may be illustrated by 
the following examples:

    Example 1. On January 1, 1990, A holds for sale 300 pounds of CFC-12 
(a post-1989 ODC not described in paragraph (d)(2) or (d)(3) of this 
section)) and 500 pounds of R-500 (a mixture). A does not hold at least 
400 pounds of ODCs that are taken into account under paragraph (e)(1) of 
this section and, under paragraph (b)(2)(i) of this section, mixtures 
are not subject to the floor stocks tax. Thus, A is not liable for the 
floor stocks tax imposed on January 1, 1990.
    Example 2. On January 1, 1990, B holds for sale 250 pounds of CFC-12 
and 250 pounds of CFC-113 (post-1989 ODCs not described in paragraph (d) 
(2) or (3) of this section). B holds 500 pounds of ODCs that are taken 
into account under paragraph (e)(1) of this section. Thus, B is liable 
for the floor stocks tax imposed on January 1, 1990, because B holds at 
least 400 pounds of ODCs for sale.
    Example 3. On January 1, 1990, C holds 200 pounds of post-1990 ODCs 
and 500 pounds of post-1989 ODCs for use in further manufacture. C will 
use 300 pounds of the post-1989 ODCs in the manufacture of rigid foam 
insulation (as defined in Sec. 52.4682-1(d) (3) and (4)). The remainder 
of the ODCs are not described in paragraph (d) (2) or (3) of this 
section. Under paragraph (e)(1) of this section, post-1990 ODCs and ODCs 
that will be used in the manufacture of rigid foam insulation are 
disregarded in determining whether the de minimis exception is 
applicable in 1990. Thus, C holds only 200 pounds of ODCs that are taken 
into account under paragraph (e)(1) of this section and is not liable 
for the floor stocks tax imposed on January 1, 1990.
    Example 4. (a) The facts are the same as in Example 3, except that 
the ODCs are held on January 1, 1991. Under paragraph (e)(2) of this 
section, the 200 pounds of post-1990 ODCs and the 300 pounds of post-
1989 ODCs that will be used in the manufacture of rigid foam insulation 
are taken into account in determining whether the de minimis exception 
is applicable in 1991. Under paragraph (b)(2) of this section, the 
remaining 200 pounds of post-1989 ODCs are not taken into account 
because the base tax amount applicable to post-1989 ODCs does not 
increase in 1991. Thus, C holds 500 pounds of ODCs that are taken into 
account under paragraph (e)(2) of this section and is liable for the 
floor stocks tax imposed on January 1, 1991.
    (b) The amount of the floor stocks tax imposed on the 200 pounds of 
post-1990 ODCs and the 300 pounds of post-1989 ODCs that will be used in 
the manufacture of rigid foam insulation is equal to the tentative tax 
amount because those ODCs were not previously subject to tax.
    Example 5. (a) On January 1, 1994, D holds for sale 300 pounds of 
CFC-113 (an ODC not described in paragraph (d)(2) or (d)(3) of this 
section) and 25 pounds of Halon-1301 (an ODC described in paragraph 
(d)(3) of this section). D is liable for the floor stocks tax imposed on 
January 1, 1994, because 25 pounds of Halon-1301 exceeds the de minimis 
amount specified in paragraph (e)(4)(iii) of this section. The 300 
pounds of CFC-113 is less than the amount specified in paragraph 
(e)(4)(i) of this section. Nevertheless, tax is imposed on both the 25 
pounds of Halon-1301 and the 300 pounds of CFC-113.
    (b) The amount of the floor stocks tax is determined separately for 
the 300 pounds of CFC-113 and the 25 pounds of Halon-1301 and is equal 
to the difference between the tentative tax amount and the amount of tax 
previously imposed on those ODCs. For Halon-1301, for example, the tax 
is determined as follows. The tentative tax amount is $1,087.50 ($4.35 
(the base tax amount in 1994) x 10 (the ozone-depletion factor for 
Halon-1301) x 25 (the number of pounds held)). The tax previously 
imposed on the Halon-1301 is $6.28 ($3.35 (the base tax amount in 1993) 
x 10 (the ozone-depletion factor for Halon-1301) x 0.75 percent (the 
applicable percentage determined under section 4682(g)(2)(A)) x 25 (the 
number of pounds

[[Page 36]]

held)). Thus, the floor stocks tax imposed on the 25 pounds of Halon-
1301 in 1994 is $1,081.22, the difference between $1,087.50 (the 
tentative tax amount) and $6.28 (the tax previously imposed).

    (f) Inventory--(1) In general. If, on the date on which the floor 
stocks tax is imposed, a person holds ODCs for sale or for use in 
further manufacture and the ODCs were not manufactured or imported by 
such person, the following rules apply:
    (i) The person shall prepare an inventory of all such ODCs that the 
person holds on the date on which the tax is imposed.
    (ii) The inventory shall be taken as of the first moment of the date 
on which the tax is imposed, but work-back or work-forward inventories 
will be acceptable if supported by adequate commercial records of 
receipt, use, and disposition of ODCs held for sale or for use in 
further manufacture.
    (iii) The person must maintain records of the inventory and make 
such records available for inspection and copying by internal revenue 
agents and officers. Records of the inventory are not to be filed with 
the Internal Revenue Service.
    (2) Circumstances in which an inventory is not required. The 
inventory requirement of paragraph (f)(1) of this section does not apply 
to any person holding, on a date on which floor stocks tax is imposed, 
only ODCs that are not subject to tax by reason of a statutory exemption 
(e.g., use as a feedstock) or regulatory exclusion other than the de 
minimis exception provided by paragraph (e) of this section (e.g., 
mixtures). In addition, any person that holds ODCs subject to the floor 
stocks tax and also holds ODCs that are nontaxable under the provisions 
of paragraph (b)(2) of this section, is not required to inventory the 
nontaxable ODCs. However, any person that holds any ODCs that either are 
subject to the floor stocks tax or would be subject to the floor stocks 
tax but for the de minimis exception must inventory those ODCs.
    (3) Examples. The rules of this paragraph (f) may be illustrated by 
the following examples:

    Example 1. On January 1, 1990, A holds for sale 300 pounds of CFC-12 
(a post-1989 ODC not described in paragraph (d)(2) or (d)(3) of this 
section) and 500 pounds of R-500 (a mixture). As required by paragraph 
(f)(1) of this section, A must prepare an inventory of the CFC-12 A 
holds for sale on that date even though, under paragraph (e)(1) of this 
section, the 300 pounds of CFC-12 is not taken into account because it 
is de minimis. However, as provided in paragraph (f)(2) of this section, 
A is not required to inventory the R-500 because, under paragraph (b)(2) 
of this section, mixtures are not subject to the floor stocks tax.
    Example 2. On January 1, 1991, B holds for sale 1,000 pounds of CFC-
12 (a post-1989 ODC not described in paragraph (d)(2) or (d)(3) of this 
section). As provided under paragraph (f)(2) of this section, B is not 
required to prepare an inventory because CFC-12 is not subject to the
