9902.10.76 - Poly(fumaric acid-co-vinyl acetate-co-vinyl chloride) (CAS No. 32650-26-3) (provided for in subheading 3904.30.60)

This HTS code, 9902.10.76, specifically classifies Poly(fumaric acid-co-vinyl acetate-co-vinyl chloride) (CAS No. 32650-26-3). This designation falls under Chapter 99, which pertains to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act. The inclusion of "provided for in subheading 3904.30.60" indicates that while the substance itself might otherwise be classified under a Chapter 39 heading (Plastics and articles thereof), this specific temporary classification imposes additional controls or restrictions.

Given that this is a leaf node within Chapter 99, there are no further subcategories for this specific entry. Its distinction from other sibling categories within Chapter 99 lies in the unique nature of the polymeric substance it covers and the specific temporary legislative or trade agreement provisions that necessitate its separate classification. Other entries in Chapter 99 would likely address different goods subject to distinct temporary measures, quotas, or special duties related to trade agreements or agricultural policy. The classification here is driven by the specific substance and the accompanying regulatory intent rather than broad product categories.
