(a) In general. The term “parts or accessories” includes (1) any article the primary use of which is to improve, repair, replace, or serve as a component part of an automobile truck or bus chasis or body, or other automobile chassis or body, or taxable tractor, (2) any article designed to be attached to or used in connection with such chassis, body, or tractor to add to its utility or ornamentation, and (3) any article the primary use of which is in connection with such chassis, body, or tractor, whether or not essential to its operation or use. The term “parts or accessories” includes all articles which have reached such a stage of manufacture as to be commonly known as parts or accessories whether or not fitting operations are required in connection with their installation. An article shall not be deemed to be a taxable part or accessory even though it is designed to be attached to the vehicle or to be primarily used in connection therewith if the article is in effect the load being transported and the primary function of the article is to serve a purpose unrelated to the vehicle as such. For example, a construction derrick attached to a truck is not a taxable part or accessory inasmuch as the derrick is the load of the truck and its use is in connection with construction work at a construction site rather than in connection with the transportation or loading or unloading function of the truck. On the other hand, an article such as a towing cradle or loading or unloading equipment designed to be attached to or to be primarily used in connection with a truck is a taxable part or accessory inasmuch as the articles contributes to the load-carrying function of the truck. The term “parts or accessories” does not include tires, inner tubes, or automobile radio or television receiving sets, since these articles are expressly exempted by section 4061(b) from the tax. However, the term “parts or accessories” includes tire valves designed for use on tires or tubes for articles taxable under section 4061(a).
(b) Articles of a general use. The term “parts or accessories” does not include articles which are not used primarily in the manufacture, repair, etc., of automobile trucks, other automobiles, or tractors, but have a general use in the manufacture, repair, etc., of various articles. For example, commodities such as ball and roller bearings, bolts, nuts, washers, screws, nails, tacks, rivets, pins, studs, cotters, pipe fittings such as plugs, tees, ells, and elbows, drain cocks, grease cups, oilers, and similar articles are not of themselves parts or accessories unless so constructed as to be used primarily in the manufacture, repair, etc., of automobile trucks, other automobiles, or tractors. On the other hand, parts for automobile parts or accessories are in themselves taxable unless they are articles of a type not specifically designed for use primarily in the automobile field. For example, the tax applies to the sale of gears, flexible shafts and flexible housings designed as replacement parts for automotive speedometers; as well as replacement parts for automobile engines, transmissions, differentials, steering mechanisms, timers, windshild-wiper motors, and other automobile parts or accessories.
(c) Materials of a general use—(1) General rule. The term “parts or accessories” also does not include material such as glass, cloth, leather, matting linoleum, and other materials sold in rolls or by the foot, such as brake lining, tape, binding, wire, cable, metal and rubber tubing, packing, conduit, and similar material. However, except as provided in subparagraph (2) of this paragraph, when any such material is cut or otherwise transformed by any person into an automobile part or accessory, tax attaches at the time such part or accessory is sold by such person.
(2) Articles made for immediate installation or repair. If in connection with an immediate installation in an automobile truck, other automobile, or tractor an article is produced through the use of special machinery or as a result of specialized skills from lengths or rolls of material, the person producing such article is considered to have manufactured an automobile part or accessory and the tax applies to his sale of such part or accessory. For example, tax applies to the sale of automobile glass cut to size to replace broken glass, or automobile seat covers, automobile floor mats, or fitted truck top covers produced to replace worn seat covers, floor mats, or truck top covers. However, if an article of a minor nature is produced by simple operation from lengths or rolls of material for immediate use by a repairman in the repair of an automobile truck, other automobile, or tractor on which he is then working, the person producing such article is not considered to have manufactured an automobile part or accessory and tax does not apply on his sale of such article. For example, tax does not apply where a wire, hose, or board is cut to size in order to replace a damaged wire, hose, or board of an automobile truck, other automobile, or tractor.
(d) Examples of articles taxable as parts or accessories. Examples of articles which are taxable as parts or accessories are: Automobile air conditioners; baby seats for automobiles; automobile beds; automobile hammocks; automobile clutches; bottle warmers and heating pads designed to operate from an automobile cigarette lighter; automobile radio antennae; automobile license plate frames; automobile clocks; automobile mirrors and mirror brackets; purses for carrying parking meter coins or cases for carrying registration cards when designed for attachment to an automobile; safes primarily designed for use in taxable motor vehicles; electric bulbs primarily designed and adapted for use on automobiles; automobile floor mats; jacks of the mechanical or hydraulic bumper, screw, ratchet, scissors, or other type primarily designed to be carried as accessories in automobiles as distinguished from jacks designed especially for use in garages and repair shops; dollies of the type commonly known as converter dollies which are used as connectors to convert semitrailers to full trailers; tool kits recommended for use with automobiles; automobile seat covers of any construction whether they are ready-made or custom fitted; fitted truck top covers; glass cut to size for installation in automobiles; and automobile bearings, such as automobile crankshaft or connecting rod bearings.
