Hydroxybenzoic acids, gallic acid, hydroxycinnamic acid, and related phenolic carboxylic acids serve as antioxidants, polymer stabilizers, pharmaceutical intermediates, and tanning agents across multiple industries. The US schedule enumerates specific compounds — including para-hydroxybenzoic acid (2918292200), gallic acid (2918293000), and 3-hydroxy-2-naphthoic acid (2918292500) — alongside basket provisions for Note 3 and non-Note 3 goods. South Korea and Japan lead US import supply for this heading, with China also a significant source, reflecting the importance of East Asian specialty-chemical producers for these intermediates.

Importers should verify current antidumping and countervailing duty orders with US Customs and Border Protection and the International Trade Commission, as trade-remedy coverage for specific organic chemicals can change. The origin of the shipment is critical, since orders are country-specific. A licensed customs broker can run a scope ruling check against active orders before importation.
Lines 2918296500 and 2918297500 separate compounds that are described in Additional US Note 3 to Section VI from those that are not. Note 3 typically covers certain chemical intermediates subject to a special duty regime. Correctly identifying whether a specific phenolic carboxylic acid falls within the Note 3 definition requires reviewing the note text and, if necessary, seeking a binding ruling from CBP, as the duty implications can differ materially between the two residual lines.
