9902.04.44 - (RS)-N,N-Diethyl-2-(1-nephthyloxy)propionamide (Napropamide) (CAS No. 15299-99-7) (provided for in subheading 2924.29.47)

This HTS classification, specifically 9902.04.44, pertains to the temporary designation for Napropamide, scientifically known as (RS)-N,N-Diethyl-2-(1-nephthyloxy)propionamide, identified by CAS Number 15299-99-7. It is important to note that while Napropamide has a primary classification within Chapter 29, its inclusion under this Chapter 99 subheading signifies a specific, temporary trade regulation or restriction. This category is distinct from the general provisions found in earlier chapters of the HTSUS which cover fundamental goods like live animals or agricultural products.

The scope of this particular subheading is narrowly defined by the specific chemical compound it addresses and its associated trade status. Unlike sibling categories within Chapter 99 that might cover other temporary measures or trade agreements affecting different classes of goods, 9902.04.44 is exclusively dedicated to Napropamide. Its existence here indicates a special circumstance, such as a temporary tariff adjustment, quota, or specific import licensing requirement, separate from its standard classification as a chemical under subheading 2924.29.47.

As this subheading represents a leaf node in the HTS structure, there are no further subcategories. Classification under 9902.04.44 is final for Napropamide under the stipulated temporary provisions. Importers and customs brokers should refer to the official notices and proclamations that established this temporary legislation to understand the precise conditions, duration, and any associated documentation required for its importation.
