9902.01.51 - Cobalt chloride (dichlorocobalt hydrate (1:1)) (CAS No. 7791-13-1) (provided for in subheading 2827.39.60)

This classification pertains to a specific chemical compound: Cobalt chloride, in its hydrated form (dichlorocobalt hydrate (1:1)), identified by CAS Number 7791-13-1. While the primary HTS classification for cobalt chloride falls under Chapter 28 (Inorganic Chemicals), this entry within Chapter 99 signifies a temporary or specific trade provision. This means that while the chemical itself is classified under a different heading (specifically subheading 2827.39.60), its importation under this particular 9902 code is subject to special rules, often related to temporary legislation, trade agreements, or specific import restrictions under Section 22 of the Agricultural Adjustment Act.

As a leaf node within Chapter 99, this classification does not have further subdivisions. Its function is to highlight a particular application or treatment for Cobalt chloride that deviates from its standard classification. Therefore, it is crucial to understand that imports of Cobalt chloride will typically be classified under subheading 2827.39.60, but if they are subject to the provisions outlined in Section XXII, then this 9902 code will be used in conjunction or as a modification. This serves to monitor or control the import of this specific chemical under certain, likely temporary, circumstances.
