Sec. 48.4081-1  Taxable fuel; definitions.

    (a) Overview. This section provides definitions for purposes of the 
tax on taxable fuel imposed by section 4081.
    (b) Definitions.
    Approved terminal or refinery means a terminal or refinery that is 
operated, respectively, by a taxable fuel registrant that is a terminal 
operator, or by a taxable fuel registrant that is a refiner.
    Aviation gasoline means all special grades of gasoline that are 
suitable for use in aviation reciprocating engines and covered by ASTM 
specification D 910 or military specification MIL-G-5572. For 
availability of ASTM and military specifications, see paragraph (d) of 
this section.
    Blender means any person that produces blended taxable fuel.
    Bulk transfer means any transfer of taxable fuel by pipeline or 
vessel.
    Bulk transfer/terminal system means the taxable fuel distribution 
system consisting of refineries, pipelines, vessels, and terminals. 
Thus, taxable fuel in a refinery, pipeline, vessel, or terminal is in 
the bulk transfer/terminal system. Taxable fuel in the fuel supply tank 
of any engine, or in any tank car, rail car, trailer, truck, or other 
equipment suitable for ground transportation is not in the bulk 
transfer/terminal system.
    Bus means automobile bus.

[[Page 108]]

    Diesel-powered bus means any bus that is propelled by a diesel-
powered engine.
    Diesel-powered highway vehicle means a highway vehicle, as defined 
in Sec. 48.4061(a)-1(d), that is propelled by a diesel-powered engine.
    Diesel-powered train means any diesel-powered equipment or machinery 
that rides on rails. Thus, for example, the term includes a locomotive, 
work train, switching engine, and track maintenance machine.
    Enterer generally means the importer of record (under customs law) 
with respect to the taxable fuel. However, if the importer of record is 
acting as an agent (for example, the importer of record is a customs 
broker engaged by the owner of the taxable fuel), the person for whom 
the agent is acting is the enterer. If there is no importer of record 
for taxable fuel entered into the United States, the owner of the 
taxable fuel at the time it is brought into the United States is the 
enterer.
    Entry of taxable fuel into the United States occurs when--
    (1) The taxable fuel is brought into the United States and 
applicable customs law requires that the taxable fuel be entered into 
the United States for consumption, use, or warehousing; or
    (2) The taxable fuel is brought into the United States from Puerto 
Rico and applicable customs law would require that the taxable fuel be 
entered into the United States for consumption, use, or warehousing if 
the taxable fuel were brought into the United States from somewhere 
other than Puerto Rico.
    Excluded liquid means any liquid that--
    (1) Contains less than four percent normal paraffins; or
    (2) Has a--
    (i) Distillation range of 125[deg] F. or less;
    (ii) Sulfur content of 10 ppm or less; and
    (iii) Minimum color of +27 Saybolt.
    Finished gasoline means all products (including gasohol (as defined 
in Sec. 48.4081-6(b)(2))) that are commonly or commercially known or 
sold as gasoline and are suitable for use as a motor fuel, other than 
products that have an ASTM octane number of less than 75 as determined 
by the motor method.
    Gasoline means finished gasoline and gasoline blendstocks.
    Industrial user means any person that receives gasoline blendstocks 
by bulk transfer for its own use in the manufacture of any product other 
than finished gasoline.
    Kerosene means any liquid that meets the specifications for kerosene 
or would meet those specifications but for the presence in the liquid of 
a dye of the type described in Sec. 48.4082-1(b). A liquid meets the 
specifications for kerosene if it is one of the two grades of kerosene 
(No. 1-K and No. 2-K) covered by ASTM specification D 3699, or kerosene-
type jet fuel covered by ASTM specification D 1655 or military 
specification MIL-DTL-5624T (Grade JP-5) or MIL-DTL-83133E (Grade JP-8). 
For availability of ASTM and military specifications, see paragraph (d) 
of this section. However, the term does not include excluded liquid.
    Position holder means, with respect to taxable fuel in a terminal, 
the person that holds the inventory position in the taxable fuel, as 
reflected on the records of the terminal operator. A person holds the 
inventory position in taxable fuel when that person has a contractual 
agreement with the terminal operator for the use of storage facilities 
and terminaling services at a terminal with respect to the taxable fuel. 
The term also includes a terminal operator that owns taxable fuel in its 
terminal.
    Rack means a mechanism capable of delivering taxable fuel into a 
means of transport other than a pipeline or vessel.
    Refiner means any person that owns, operates, or otherwise controls 
a refinery.
    Refinery means a facility used to produce taxable fuel and from 
which taxable fuel may be removed by pipeline, by vessel, or at a rack. 
However, the term does not include a facility where only blended fuel or 
gasohol (as defined in Sec. 48.4081-6(b)(2)), and no other type of 
taxable fuel, is produced. For this purpose blended fuel is any mixture 
that, if produced outside the bulk transfer/terminal system, would be 
blended taxable fuel.

[[Page 109]]

    Removal means any physical transfer of taxable fuel, and any use of 
taxable fuel other than as a material in the production of taxable fuel 
or special fuels. However, taxable fuel is not removed when it 
evaporates or is otherwise lost or destroyed.
    Sale means--
    (1) The transfer of title to, or substantial incidents of ownership 
in, taxable fuel (other than taxable fuel in a terminal) to the buyer 
for a consideration, which may consist of money, services, or other 
property; or
    (2) The transfer of the inventory position in the taxable fuel in a 
terminal if the transferee becomes the position holder with respect to 
the taxable fuel.
    State includes any State, any political subdivision of a State, the 
District of Columbia, the American Red Cross, and, to the extent 
provided by section 7871, any Indian tribal government.
    Taxable fuel means gasoline, diesel fuel, and kerosene.
    Taxable fuel registrant means an enterer, industrial user, refiner, 
terminal operator, or throughputter that is registered as such under 
section 4101.
    Terminal means a taxable fuel storage and distribution facility that 
is supplied by pipeline or vessel and from which taxable fuel may be 
removed at a rack. However, the term does not include any facility at 
which gasoline blendstocks are used in the manufacture of products other 
than finished gasoline and from which no gasoline is removed. Also, 
effective January 2, 1998, the term does not include any facility where 
finished gasoline, undyed diesel fuel, or undyed kerosene is stored if 
the facility is operated by a taxable fuel registrant and all such 
taxable fuel stored at the facility has been previously taxed under 
section 4081 upon removal from a refinery or terminal.
    Terminal operator means any person that owns, operates, or otherwise 
controls a terminal.
    Throughputter means any person that--
    (1) Owns taxable fuel within the bulk transfer/terminal system 
(other than in a terminal); or
    (2) Is a position holder.
    Vessel means a waterborne taxable fuel transporting vessel.
    (c) Blended taxable fuel, diesel fuel, and gasoline blendstocks; 
definitions--(1) Blended taxable fuel--(i) In general. Except as 
provided in paragraphs (c)(1)(ii) and (c)(1)(iii) of this section, 
blended taxable fuel means any taxable fuel that is produced outside the 
bulk transfer/terminal system by mixing--
    (A) Taxable fuel with respect to which tax has been imposed under 
section 4041(a)(1) or 4081(a) (other than taxable fuel for which a 
credit or payment has been allowed); and
    (B) Any other liquid on which tax has not been imposed under section 
4081.
    (ii) Exclusion; minor blending. A mixture described in paragraph 
(c)(1)(i) of this section is not blended taxable fuel if, during the 
calendar quarter in which the blender removes or sells the mixture, all 
such mixtures removed or sold by the blender contain, in the aggregate, 
less than 400 gallons of liquid described in paragraph (c)(1)(i)(B) of 
this section.
    (iii) Exclusion; gasohol. Blended taxable fuel does not include any 
gasohol (as defined in Sec. 48.4081-6(b)(2)) if, disregarding the 
alcohol, the gasohol is not blended taxable fuel and contains, in 
addition to permitted amounts of liquids described in paragraph 
(c)(1)(i)(B) of this section, only gasoline with respect to which--
    (A) Tax was imposed under section 4081(a) at a rate described in 
Sec. 48.4081-6(e) (relating to the gasohol production tax rate and the 
gasohol tax rate); or
    (B) A valid claim is made under section 6427(f).
    (2) Diesel fuel--(i) In general. Except as provided in paragraph 
(c)(2)(ii) of this section, diesel fuel means any liquid that, without 
further processing or blending, is suitable for use as a fuel in a 
diesel-powered highway vehicle or diesel-powered train. A liquid is 
suitable for this use if the liquid has practical and commercial fitness 
for use in the propulsion engine of a diesel-powered highway vehicle or 
diesel-powered train. A liquid may possess this practical and commercial 
fitness even though the specified use is not the liquid's predominant 
use. However, a liquid does not possess this practical and commercial 
fitness solely by reason of its possible or rare use as a fuel in the 
propulsion engine of a diesel-powered

[[Page 110]]

highway vehicle or diesel-powered train.
    (ii) Exclusion. Diesel fuel does not include gasoline, kerosene, 
excluded liquid, No. 5 and No. 6 fuel oils covered by ASTM specification 
D 396, or F-76 (Fuel Naval Distillate) covered by military specification 
MIL-F-16884. For availability of ASTM and military specifications, see 
paragraph (d) of this section.
    (3) Gasoline blendstocks--(i) In general. Except as provided in 
paragraph (c)(3)(ii) of this section, gasoline blendstocks means--
    (A) Alkylate;
    (B) Butane;
    (C) Butene;
    (D) Catalytically cracked gasoline;
    (E) Coker gasoline;

    (V) Thermally cracked gasoline;
    (W) Toluene; and
    (X) Transmix containing gasoline.

    (ii) Exclusion. Gasoline blendstocks does not include any product 
that cannot, without further processing, be used in the production of 
finished gasoline. For example, a mixed hydrocarbon stream that is 
produced in a natural gas processing plant is not a gasoline blendstock 
if the stream cannot be used to produce finished gasoline without 
further processing.
    (d) ASTM and military specifications. ASTM specifications may be 
obtained from the American Society for Testing and Materials, 100 Barr 
Harbor Drive, West Conshohocken, PA 19428. Military specifications may
