9902.01.60 - Cobalt carbonate (cobalt(2+) carbonate hydrate (1:1:1)) (CAS No. 513-79-1) (provided for in subheading 2836.99.10)

This HTS category, 9902.01.60, specifically classifies Cobalt carbonate (cobalt(2+) carbonate hydrate (1:1:1)), identified by CAS Number 513-79-1. It is important to note that this is a temporary classification provision, indicating that it falls under Chapter 99 of the Harmonized Tariff Schedule, which deals with temporary legislation and modifications. The description explicitly directs users to its primary classification under subheading 2836.99.10 for general carbonate classification.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its purpose is to implement specific temporary import restrictions or modifications for this particular chemical compound. Unlike the preceding sibling categories in Chapter 99, which may address a variety of temporary trade measures, this entry is exclusively dedicated to cobalt carbonate. The distinction lies in the specific commodity and the unique temporary control it is subject to, rather than a broad category of goods.

Therefore, importers and customs professionals encountering this HTS code should recognize it as a specialized, temporary designation for cobalt carbonate that supersedes its standard classification under Chapter 28, for the duration of the temporary measure's applicability. This provision is crucial for ensuring compliance with current trade policies affecting this specific chemical.
