Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hydrogenated benzothiazole variant
Hydrogenated forms have separate subheading within benzothiazoles.
If emphasizing saturated acyclic structure over ring
Acyclic alcohol derivatives might apply but ring specificity controls.
If marketed solely as pesticide intermediate
Goods of chapter 38 if primary use shifts from chemical identity.

2,2'-Dithiobisbenzothiazole (DMTS)
2,2'-Dithiobisbenzothiazole, also known as DMTS or bis(2-benzothiazolyl) disulfide, is a sulfur-containing heterocyclic compound featuring a benzothiazole ring system. It falls under HTS 2934.20.10.00 as a specific compound containing the benzothiazole ring (whether hydrogenated or not) that is not further fused with other rings. Primarily used as a vulcanization accelerator in rubber production.
Captax MBTS Rubber Accelerator
Captax MBTS is the commercial grade 2,2'-dithiobisbenzothiazole used in tire and rubber manufacturing as a delayed-action vulcanization accelerator. Classified under HTS 2934.20.10.00 due to its specific benzothiazole ring structure as a separate chemically defined organic compound. It improves scorch safety in natural and synthetic rubber compounds.
NOBS-60 Pre-Dispersed MBTS Accelerator
NOBS-60 is a 60% dispersion of 2,2'-dithiobisbenzothiazole on polymer carrier for even distribution in rubber mixes. Despite dispersion, the active ingredient's benzothiazole structure qualifies it under HTS 2934.20.10.00 as the principal compound. Used in automotive belts and hoses for controlled vulcanization.
Benzothiazole Disulfide Powder 98%
Technical grade 98% 2,2'-dithiobisbenzothiazole powder for large-scale rubber processing plants. Classified precisely under HTS 2934.20.10.00 for its chemically defined benzothiazole structure with allowable impurities per chapter notes. Essential for conveyor belt and footwear production.
