Overview

This HTS category, 9902.11.59, specifically covers sodium alginate, identified by CAS No. 9005-38-3. While sodium alginate is chemically classified under subheading 3913.10.00 as a modified natural polymer, its inclusion in Chapter 99 signifies a temporary legislative or trade agreement-related provision. This means that imports of sodium alginate under this 9902 code are subject to specific, potentially time-limited, restrictions, duties, or reporting requirements that may differ from its standard classification.

The purpose of Chapter 99, where this code resides, is to implement temporary measures, including those stemming from trade agreements or Section 22 of the Agricultural Adjustment Act. Therefore, unlike its direct chemical classification siblings under Chapter 39 (Plastics and articles thereof), which deal with the permanent categorization of plastics and derived materials, HTS 9902.11.59 addresses a specific import policy or trade management aspect pertaining to sodium alginate.

As this node represents a leaf node within its specific chapter, there are no further subdivisions. Classification within 9902.11.59 is dependent on meeting the conditions of the temporary legislation or trade proclamation under which it was established. Importers should consult the relevant trade notices and regulations associated with this specific HTS code to ensure full compliance with any stipulated requirements, which may include quotas, special tariffs, or specific documentation beyond the standard import procedures.
