9902.03.10 - 3,4,5-Trihydroxybenzoic acid monohydrate (Gallic acid monohydrate) (CAS No. 5995-86-8) (provided for in subheading 2918.29.30)

This HTS category, 9902.03.10, specifically covers 3,4,5-Trihydroxybenzoic acid monohydrate, commonly known as Gallic acid monohydrate. Its CAS number is 5995-86-8. While the primary classification for this substance under the standard HTS structure is found in subheading 2918.29.30 (which pertains to carboxylic acids with additional oxygen atoms and their anhydrides, halides, acid chlorides, acid anhydrides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives), this Chapter 99 provision likely represents a temporary modification, quota, or specific restriction related to its import.

As a leaf node within Chapter 99, this entry does not have further subcategories. Its uniqueness lies in its specific designation as a temporary or special classification. Unlike the numerous sibling categories starting with "0101" through "0105" and beyond, which deal with live animals, this category is entirely distinct, focusing on a specific chemical compound rather than living organisms. The purpose of this Chapter 99 entry is to apply a particular tariff or control mechanism to Gallic acid monohydrate that deviates from its standard classification under Chapter 29. Therefore, importers must consult the notes and specific proclamations associated with Chapter 99 to understand the exact implications of this classification for their shipments.
