Overview

This HTS category, 9902.11.11, specifically covers a starch-g-poly (propenamide-co-2-propenoic acid) potassium salt, also known by the trade name "Zeba" and identified by CAS Number 863132-14-3. While the primary classification for this type of superabsorbent polymer is found in subheading 3906.90.50, this entry within Chapter 99 signifies a temporary modification or restriction. It is crucial for importers to recognize that this entry does not represent a standard classification but rather a specific, potentially time-limited provision.

Unlike the general classifications found in Chapters 1 through 97 of the Harmonized Tariff Schedule, which aim for permanent categorization of goods, Chapter 99 is reserved for temporary legislation, trade agreement modifications, and measures enacted under Section 22 of the Agricultural Adjustment Act. Therefore, this category does not have direct "sibling" categories in the traditional sense of similar products at the same hierarchical level. Its existence is driven by specific policy decisions rather than inherent product characteristics, setting it apart from the broad array of goods classified in the earlier chapters.

As this node is a leaf node, there are no further subcategories. The classification is definitive for the product described. Any product fitting the description of starch-g-poly (propenamide-co-2-propenoic acid) potassium salt (CAS No. 863132-14-3) is intended to be processed under this specific provision. Importers should always consult the latest official HTS publications to confirm the current status and applicability of temporary provisions within Chapter 99.
