9902.11.10 - Poly(methyl acrylate-co-methyl methacrylate-co-methacrylic acid) 7:3:1 (CAS No. 26936-24-3) (provided for in subheading 3906.90.50)

This HTS category, 9902.11.10, specifically covers a particular type of copolymer: Poly(methyl acrylate-co-methyl methacrylate-co-methacrylic acid) in a 7:3:1 ratio, identified by CAS Number 26936-24-3. This classification is part of Section XXII, which deals with temporary legislation and trade agreement modifications, and Chapter 99, which houses temporary measures and additional import restrictions. This particular item is provided for under subheading 3906.90.50, indicating its underlying nature as a synthetic polymer.

As a leaf node within the HTS, there are no further subcategories for this specific item. Its distinct nature is defined by its precise chemical composition and ratio of monomers. Classification decisions within Chapter 99 are highly specific, often addressing unique situations or temporary measures related to trade policy or agricultural adjustments, differentiating it from the broad, commodity-based classifications found in earlier chapters of the HTS that cover live animals, meats, dairy, and other general merchandise.
