9902.10.26 - Mixtures of caprolactam disulfide (CAS No. 23847-08-7) with an elastomer binder of ethylene-propylene-diene monomer and ethyl vinyl acetate, and dispersing agents (provided for in subheading 3812.10.50)

This HTS classification pertains to specific chemical mixtures containing caprolactam disulfide. The defining characteristic of these mixtures is the inclusion of caprolactam disulfide (CAS No. 23847-08-7) bound together with an elastomer binder composed of ethylene-propylene-diene monomer (EPDM) and ethyl vinyl acetate (EVA). Additionally, these mixtures incorporate dispersing agents, and their classification is explicitly linked to subheading 3812.10.50, which covers pre-dispersed chemicals for rubber.

Unlike other categories within Chapter 99 that might deal with temporary trade modifications or specific import restrictions on broader categories of goods, this subheading targets a very particular type of chemical formulation. Its distinction lies in its precise composition: the combination of caprolactam disulfide with a specific elastomer binder and dispersing agents, intended for use in rubber compounding. Other chemical mixtures or preparations, even those containing some of the same components but lacking this specific combination or intended use, would be classified elsewhere in the HTS.

As a leaf node, HTS code 9902.10.26 does not have further subdivisions. Therefore, classification under this code is dependent on meeting all the specified criteria regarding the presence of caprolactam disulfide, the specific elastomer binder (EPDM and EVA), dispersing agents, and the intended application within the rubber industry, as guided by the parent provision under subheading 3812.10.50.
