9902.10.99 - Poly(vinyl acetate-co-crotonic acid) (CAS No. 25609-89-6) (provided for in subheading 3905.19.00)

This HTS category, 9902.10.99, specifically covers Poly(vinyl acetate-co-crotonic acid) (CAS No. 25609-89-6). This particular copolymer falls under temporary legislation and special classification provisions, as indicated by its placement within Chapter 99. Its inclusion here signifies a specific import status or restriction separate from its general classification under Chapter 39 (Plastics and articles thereof), where it is referenced as being provided for in subheading 3905.19.00.

Distinguishing this category from its "sibling" entries within Chapter 99 requires understanding the nature of Chapter 99 itself. Chapter 99 is a repository for temporary measures, trade agreement modifications, and specific statutory restrictions, often relating to agricultural goods under Section 22 of the Agricultural Adjustment Act. Therefore, 9902.10.99 is not distinguished from other Chapter 99 entries based on the physical characteristics of the polymer itself, but rather on the specific legal or trade-related provisions that govern its importation. Each entry within Chapter 99 represents a unique temporary modification or restriction applied to otherwise classified goods.

As this is a leaf node, there are no subcategories to introduce. The classification ends with this specific provision for Poly(vinyl acetate-co-crotonic acid). The importance of this classification lies in adhering to the specific duties, quotas, or other requirements that may be imposed by this temporary measure, which take precedence over its standard HTS classification. Importers must consult the full text of the relevant temporary legislation or proclamation to understand the precise implications of this designation.
