9902.01.59 - Ammonium polyphosphate (CAS No. 68333-79-9) (provided for in subheading 2835.39.50)

This HTS category, 9902.01.59, is reserved for specific temporary legislation concerning ammonium polyphosphate (CAS No. 68333-79-9). Importantly, this classification is "provided for in subheading 2835.39.50," indicating that the substance itself falls under a different, permanent HTS chapter related to mineral products and salts. This chapter 9902 entry signifies a temporary modification or restriction applied to ammonium polyphosphate under specific trade agreements or pursuant to section 22 of the Agricultural Adjustment Act.

Given that this is a leaf node and falls under Section XXII: Special Classification Provisions, it does not have direct siblings at the HTS Database Root level in the typical sense of product categories. Its unique position within Chapter 99 highlights its role as a regulatory overlay rather than a primary product classification. Any distinctions would be with other Chapter 99 provisions that may apply temporary measures to different goods.

As a leaf node, there are no subcategories to introduce. Classification under 9902.01.59 is definitive for ammonium polyphosphate when subject to the specific temporary provisions outlined in the parent context. Importers and exporters should consult the relevant trade agreements or proclamations associated with this code to understand the specific requirements, duties, or restrictions that may apply.
