Benzoic Anhydride
Benzoic anhydride is the anhydride of benzoic acid, a cyclic aromatic monocarboxylic acid derivative used primarily as an acylating agent in organic synthesis for producing pharmaceuticals, fragrances, and resins. It falls under HTS 2916.39.03.00 as a specifically named aromatic monocarboxylic acid anhydride. Typically supplied as a white crystalline solid in industrial packaging for chemical manufacturing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing unreacted benzoic acid impurities exceeding 5%
Mixtures with significant parent acid content may classify under benzoic acid heading per chapter note on impurities.
If when imported as a formulated solution for retail lab use
Chemical preparations not meeting Chapter 29 purity criteria fall into mixtures of Chapter 38.
If for other unspecified aromatic acid anhydrides like phthalic anhydride
Specific enumeration takes precedence; non-listed anhydrides go to residual 'other' subheading.

Import Tips & Compliance
• Provide detailed chemical composition certificates and Safety Data Sheets (SDS) compliant with TSCA for US customs clearance
• Verify purity levels (>98%) as impurities may trigger reclassification under general 'other' subheadings
• Ensure proper UN-approved packaging for corrosive solids to avoid hazmat surcharges or delays
