9902.11.09 - Poly(methacrylic acid-co-methyl methacrylate) (CAS No. 25086-15-1) (provided for in subheading 3906.90.50)

HTS Code 9902.11.09 pertains to Poly(methacrylic acid-co-methyl methacrylate) (CAS No. 25086-15-1), specifically when it is provided for under subheading 3906.90.50. This classification falls under Chapter 99 of the Harmonized Tariff Schedule, which designates temporary legislation, temporary modifications pursuant to trade agreements, and additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act. Therefore, goods classified here are subject to specific, often time-limited, import regulations and potential restrictions that are separate from their standard tariff classification.

This category is distinguished from its siblings within Chapter 99 by its specific reference to a particular chemical compound, Poly(methacrylic acid-co-methyl methacrylate), and its linkage to subheading 3906.90.50. While other 99xx codes might address various temporary measures affecting different classes of goods, 9902.11.09 is precisely targeted at this copolymer. The "provided for in subheading 3906.90.50" clause is critical, indicating that the primary classification of the material is as a synthetic polymer of acrylic acid or its derivatives (under Chapter 39), but it is being subjected to an additional, temporary trade regulation under Chapter 99.

As this node is a leaf node, there are no further subcategories. The classification of Poly(methacrylic acid-co-methyl methacrylate) under 9902.11.09 signifies that, in addition to its standard tariff treatment under Chapter 39, it is currently subject to specific temporary import provisions. Importers must consult the detailed regulations and quotas associated with this HTS code, as these provisions are dynamic and can impact duties, quantities, and other import requirements.
