1-Hydroxy-6-octadecyloxy-2-naphthalene-carboxylic acid
This is a specific aromatic carboxylic acid with an additional hydroxy group and a long C18 octadecyloxy chain attached to the naphthalene ring. It falls under HTS 2918.99.0600 as it is explicitly named in the tariff subheading for chemically defined organic compounds with oxygen functions. Primarily used as an intermediate in synthesizing surfactants, dyes, and polymers.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a mixture with isomers or impurities exceeding 2%
Mixtures of isomers fall under general 'other' aromatic carboxylic acids rather than specific named compounds.
If dissolved in solvent for safe transport (e.g., ethanol solution)
Solutions in solvents for transport safety classify as chemical preparations in Chapter 38 per chapter note (e).
If primarily valued as fragrance intermediate rather than acid-function compound
Ether-alcohol derivatives with perfumery use may shift to Chapter 29 alcohol/phenol ethers.

Import Tips & Compliance
• Provide detailed chemical analysis (NMR, MS) and CoA to confirm identity as the exact named compound, avoiding misclassification
• Ensure packaging complies with UN/DOT hazardous material regs if shipped in quantities >1kg due to potential irritant properties
• Declare purity level (>98%) on commercial invoice; impurities may trigger reclassification under 'other' aromatic acids
