Notes

1.   Except where the context otherwise requires, throughout the export schedule the
     expression "rubber" means the following products, whether or not vulcanized or hard:
     natural rubber, balata, gutta-percha, guayule, chicle and similar natural gums, synthetic
     rubber, factice derived from oils, and such substances reclaimed.

2.   This chapter does not cover:

     (a). Goods of section XI (textiles and textile articles);

     (b). Footwear or parts thereof of chapter 64;

     (c). Headgear of parts thereof (including bathing caps) of chapter 65;

     (d). Mechanical or electrical appliances or parts thereof of section XVI (including
          electrical goods of all kinds), of hard rubber;

     (e). Articles of chapters 90, 92, 94 or 96; or

     (f). Articles of chapter 95 (other than sports gloves, mittens and mitts and articles of
          headings 4011 to 4013).

3.   In headings 4001 to 4003 and 4005 the expression "primary forms" applies only to the 
     following forms:

     (a). Liquids and pastes (including latex, whether or not prevulcanized, and other
          dispersions and solutions);

     (b). Blocks of irregular shape, lumps, bales, powders, granules, crumbs and similar
          bulk forms.

4.   In note 1 to this chapter and in heading 4002, the expression "synthetic rubber" applies to:

     (a). Unsaturated synthetic substances which can be irreversibly transformed by
          vulcanization with sulfur into non-thermoplastic substances which, at a
          temperature between 18 degrees C and 29 degrees C, will not break on being
          extended to three times their original length and will return, after being extended
          to twice their original length, within a period of five minutes, to a length not
          greater than one and a half times their original length.  For the purposes of this
          test, substances necessary for the cross-linking, such as vulcanizing activators or
          accelerators, may be added; the presence of substances as provided for by note 5
          (b) (ii) and (iii) is also permitted.  However, the presence of any substances not
          necessary for the cross-linking, such as extenders, plasticizers and fillers, is not
          permitted;

     (b). Thioplasts (TM); and

     (c). Natural rubber modified by grafting or mixing with plastics, depolymerized natural
          rubber, mixtures of unsaturated synthetic substances with saturated synthetic high
          polymers provided that all the above-mentioned products comply with the
          requirements concerning vulcanization, elongation and recovery in (a) above.

5.   As follows:

     (a). Headings 4001 and 4002 do not apply to any rubber or mixture of rubbers which
          has been compounded, before or after coagulation, with:

          (i). Vulcanizing agents, accelerators, retarders or activators (other than those
               added for the preparation of prevulcanized rubber latex);

          (ii).     Pigments or other coloring matter other than those added solely for the
                    purpose of identification;

          (iii).    Plasticizers or extenders (except mineral oil in the case of oil-extended
                    rubber), fillers, reinforcing agents, organic solvents or any other
                    substances, except those permitted under (b);

     (b). The presence of the following substances in any rubber or mixture of rubbers shall
          not affect its classification in heading 4001 or 4002 as the case may be, provided
          that such rubber or mixture of rubbers retains its essential character as a raw
          material:

          (i). emulsifiers or antitack agents;

          (ii).     small amounts of breakdown products of emulsifiers;

          (iii).    very small amounts of the following: heat-sensitive agents (generally for
                    latexes), cationic surface-active agents (generally for obtaining
                    electro-positive rubber latexes), agents, peptizers, preservatives,
                    stabilizers, viscosity-control agents, or similar special-purpose additives.

6.   For the purposes of heading 4004 the expression "waste, parings and scrap" means rubber
     waste, parings and scrap from the manufacture or working of rubber and rubber goods
     definitely not usable as such because of cutting-up, wear or other reasons.

7.   Thread wholly of vulcanized rubber, of which any cross-sectional dimension exceeds 5
     mm (0.2 in.), is to be classified as strip, rods or profile shapes, of heading 4008.

8.   Heading 4010 includes conveyor or transmission belts or belting of textile fabric
     impregnated, coated, covered or laminated with rubber or made from textile yarn or cord
     impregnated, coated, covered or sheathed with rubber.

9.   In headings 4001, 4002, 4003, 4005, and 4008, the expressions "plates", "sheets" and
     "strip" apply only to plates, sheets, strip and to blocks of regular geometric shape, uncut
     or simply cut to rectangular (including square) shape, whether or not having the character
     of articles and whether or not printed or otherwise surface-worked, but not otherwise cut
     to shape or further worked.

     In heading 4008, the expressions "rods" and "profile shapes" apply only to such products,
     whether or not cut to length or surface-worked but not otherwise worked.
