Division 5

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

1. (1)

   vulcanising agents, accelerators, retarders or activators (other than those added for the preparation of pre-vulcanised rubber latex);

2. (2)

   pigments or other colouring matter, other than those added solely for the purpose of identification;

3. (3)

   plasticisers 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).

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:

1. (1)

   emulsifiers or anti-tack agents;

2. (2)

   small amounts of breakdown products of emulsifiers;

3. (3)

   very small amounts of the following: heat-sensitive agents (generally, for obtaining thermosensitive rubber latexes), cationic surface-active agents (generally, for obtaining electropositive rubber latexes), antioxidants, coagulants, crumbling agents, freeze-resisting agents, peptisers, preservatives, stabilisers, viscosity-control agents, or similar special-purpose additives.
