9902.10.31 - Zinc 4-methyl-1H-benzimidazole-2-thiolate (CAS No. 61617-00-3) (provided for in subheading 3812.39.60)

This HTS category, 9902.10.31, specifically covers Zinc 4-methyl-1H-benzimidazole-2-thiolate, identified by CAS No. 61617-00-3. This chemical compound is classified under temporary legislation and modifications, as indicated by its Chapter 99 designation. Its primary classification for tariff purposes is found under subheading 3812.39.60, which pertains to pre-tanned leather and other preparations, implying its use in industrial applications such as rubber or plastic additives.

Given its placement within Chapter 99, this entry signifies a temporary measure or special provision distinct from the permanent classifications found in the earlier chapters of the HTS. Unlike the broad categories of goods such as live animals or basic commodities represented by the sibling categories (e.g., 0101 for live horses, 0102 for live bovine animals), 9902.10.31 addresses a very specific chemical substance with particular import regulations. The siblings are characterized by broad agricultural or animal product groupings, whereas this entry is focused on a specialized industrial chemical under temporary HTS provisions.

As this is a leaf node, there are no further subcategories within 9902.10.31. Classification under this heading is definitive for Zinc 4-methyl-1H-benzimidazole-2-thiolate when imported under the conditions specified by Chapter 99. Importers should note that the reference to subheading 3812.39.60 indicates the underlying permanent classification framework, but the Chapter 99 designation imposes specific, potentially time-limited, import requirements or duty rates.
