Phthalic Anhydride from China

Phthalic anhydride is an acyclic polycarboxylic acid derivative produced by the oxidation of naphthalene or o-xylene, both aromatic hydrocarbons. It falls under HTS 2917.19.40.00 as it is derived in whole or in part from aromatic hydrocarbons and used primarily in plasticizers and resins. This classification applies to its pure chemical form meeting chapter 29 notes for separate chemically defined organic compounds.

Import Tips

Verify purity and certificate of analysis to confirm it meets 'separate chemically defined compound' criteria under Chapter 29 note (a)

Provide documentation proving derivation from aromatic hydrocarbons like o-xylene to avoid reclassification

Ensure proper Hazard Communication labeling as it's a corrosive substance; common pitfall is inadequate MSDS
