9902.02.24 - Pyrogallol (Pyrogallic acid) (CAS No. 87-66-1) (provided for in subheading 2907.29.10)

This HTS classification, 9902.02.24, specifically covers Pyrogallol, also known as Pyrogallic acid (CAS No. 87-66-1). This chemical compound is a trihydroxybenzene, typically appearing as a white crystalline solid. Its presence within Chapter 99 of the Harmonized Tariff Schedule indicates that it is subject to temporary legislation, modifications, or additional import restrictions proclaimed under specific trade agreements or agricultural adjustment legislation.

As this is a leaf node within Chapter 99, there are no further subcategories to detail. The classification is precise, designating Pyrogallol for specific import control measures. While other chemical compounds might fall under different HTS codes, such as those within Chapter 29 (Organic Chemicals), this entry under Chapter 99 highlights that Pyrogallol is being treated under a distinct set of temporary trade provisions, overriding its standard classification in Chapter 29 (specifically, subheading 2907.29.10 as indicated in the description). This distinction is crucial for importers and customs brokers to ensure compliance with all applicable regulations beyond the standard tariff classification.
