9902.01.64 - Potassium Ferrocyanide (CAS No.14459-95-1) (provided for in subheading 2837.20.51)

This HTS category, 9902.01.64, specifically covers Potassium Ferrocyanide, identified by CAS Number 14459-95-1. While the Harmonized Tariff Schedule has numerous chapters dedicated to the classification of goods, this particular entry falls under Chapter 99, which is reserved for temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions. The underlying classification for Potassium Ferrocyanide is found in subheading 2837.20.51, indicating its place within the broader chemical classifications, specifically under cyanides, cyanate, and ferrocyanides, ferricyanides.

As a specific temporary provision, this category's significance lies in its unique status within the broader HTS framework. Its siblings at the Chapter 99 level represent a diverse array of temporary measures, such as quotas, special tariff rates for specific trade agreements, or restrictions related to agricultural policies. Category 9902.01.64 is distinct because it carves out Potassium Ferrocyanide for a specific, likely temporary, trade or regulatory treatment that deviates from its standard classification under Chapter 28.

Given that this is a leaf node within the HTS database, there are no further subcategories. Therefore, the classification of Potassium Ferrocyanide under 9902.01.64 is the most specific designation available for this particular import scenario. Importers must refer to the accompanying notes and rulings for this specific HTS code to understand the precise conditions and requirements associated with importing Potassium Ferrocyanide under this special provision.
