Overview
This HTS category, 9902.10.28, specifically covers a specialized mixture designed for industrial applications. The primary component is zinc dicyanato diamine, a compound identified by CAS No. 122012-52-6. This zinc compound is expertly combined with an elastomer binder, formed from ethylene-propylene-diene monomer and ethyl vinyl acetate, and further enhanced with dispersing agents. These dispersing agents are themselves classified under subheading 3812.10.50, indicating their role in stabilizing the mixture. The overall composition suggests a product engineered for specific performance characteristics, likely related to adhesion, sealing, or protective coatings.
Distinguishing this category from its siblings, which are primarily concerned with live animals across various species (e.g., horses, bovine, swine, sheep, goats, poultry), is fundamental. HTS 9902.10.28 falls under Chapter 99, which pertains to temporary legislation and special provisions, particularly modifications and restrictions enacted under trade agreements and Section 22 of the Agricultural Adjustment Act. Therefore, unlike the straightforward biological classification of its siblings, this entry is driven by trade policy and specific regulatory controls rather than inherent product type. Its inclusion in Chapter 99 signifies that its importation or exportation may be subject to unique duties, quotas, or other specific requirements not applicable to general merchandise.
As HTS Code 9902.10.28 is a leaf node, there are no further subcategories. Classification under this specific code is final and requires a precise match to the described composition and its regulatory context within Chapter 99. Importers and exporters must ensure that the goods they are declaring precisely match the description, including the specified chemical compound and binder, to correctly utilize this provision. The presence of the CAS number further emphasizes the need for accurate chemical identification.
