Chapter 40
(Section VII:- Plastics and articles thereof; Rubber and articles thereof)

Notes:

1. Except where the context otherwise requires, throughout this Schedule, the expression rubber means the following products whether or nofvulcanised or hard: natural rubber, balata, guttapercha, 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 or parts thereof (including bathing caps) of Chapter 65;
(d) Mechanical or electrical appliances or parts thereof of Section XVI (in- cluding electrical goods of all kinds), of hard rubber;
(e) Articles of Chapter 90,92,94 or 96; or
(f) Articles of Chapter 95 (other than sports gloves and articles of heading Nos. 40.11 to 40.13).

3. In heading Nos. 40.02, 40.03 and 40.05, the expression primary forms applies only to liquids and pastes (including latex, whether or not prevulcanised, and other dispersions and solutions), and blocks of irregular shape, lumps, bales, powders, granules, crumbs and similar bulk forms.

4. In Note 1 above and in heading No. 40.02, the expression synthetic rubber applies to :
(a) Unsaturated synthetic substances which can be irreversibly transformed by vulcanisation with sulphur into non-thermoplastic substances which, at a temperature between 18°C and 29°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 vulcanising activators or accelerators, may be added; the presence of suostances 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, plasticisers and fillers, is not permitted;
(b) Thioplasts (TM); and
(c) Natural rubber modified by grafting or mixing with plastics, depolymerisednatural rubber, mixture of unsaturated synthetic sub- stances with saturated synthetic high polymers provided that all the above-mentioned products comply with the requirements concerning vulcanisation, elongation and recovery in (a) above.

5. (a) Heading Nos. 40.01 and 40.02 do not apply to any rubber or mixture of rubbers which has been compounded, before or after coagulation with :
(i) vulcanising agents, accelerators, retarders or activators (other than those added for the preparation of prevulcanised rubber latex);
(ii) pigments or other colouring matter, other than those added solely for the purpose of identification;
(iii) plasticisers or extenders (except mineral oil in the case of oil-extended rubber), fillers, reinforcing agents, organic solvents or any other sub- stances, except those permitted under (b);

(b) The presence of the following substances in any rubber or mixture of mbbers shall not affect its classification in heading No. 40.01 or 40.02, as the case may be, provided that such rubber or mixture of rubbers retains its essential character as a raw material :
(i) emulsifiers or anti-tack agents;
(ii) small amounts of breakdown products of er.lulsifiers;
(iii) very small amounts of the following: heat-sensitive agents (generally for obtaining thermosensitive rubber latexes), cationic surface-active agents (generally for obtaining electro-positive rubber latexes), antiox- idants, coagulants, crumbling agents, freeze-resisting agents, peptisers, preservatives, stabilisers, viscosity-control agents or similar special purpose additives.

6. For the purposes of heading No. 40.04, the expression waste, parings and scrap means rubber waste, parings and scrap from the manufacture of working of rubber and rubber goods definitely not usable as such because of cutting-up, wear or other reasons.

7. Thread wholly of vulcanised rubber, of which any cross-sectional dimension exceeds 5 mm, is to be classified as strip, rods or profile shapes, of heading No. 40.08.

8. Heading No. 40.10 includes conveyor or transmission belts or belting of textile fabric impregnated, coated, covered or laminated with rubber or made from textile yam or cord impregnated, coated, covered or sheathed with rubber .

9. In heading Nos. 40.01,40.02, 40.03,40.05 and 40.08, except as otherwise provided, the ~xpressions plates, sheets and strips apply only to plates, sheets and strip and to blocks of regular geometric shape, ).lncut 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 No. 40.08, the expressions rods and profile shapes apply only to such products, whether or not cut to length or surface-worked but not otherwise worked. Sub-heading No. 4008.21 shall also apply to "plates", "sheets" and "strips", whether or not cut to shape and surface-worked or further worked so as to render them fit for resoling or repairing or re-treading of rubber-tyres.

10. For the purposes of heading Nos. 40.09 and 40.10, while calculating the percentage of rubber compound contents, the weight of canvas, yam, metallic wires, washers, rivets and the like, which products, shall form integral part or ingredient of such rubber products, shall be taken into an account, but the weight of metallic fitments and surface finishing necessary to make the betting and tubing suitable for particular end uses, shall be ignored.
