Adipic Acid (Hexanedioic Acid)
Adipic acid is a white, crystalline dicarboxylic acid (HOOC-(CH2)4-COOH) used primarily in nylon production. It falls under HTS 2917.12.1000 as a chemically defined acyclic polycarboxylic acid. This classification covers the pure compound without salts or esters.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as aqueous solution for safety/transport
Solutions of adipic acid in water qualify under Chapter 29 note (d) but may shift if solvent renders it for specific use.
If mixed with impurities exceeding trace levels
Mixtures of organic compounds not meeting 'chemically defined' criteria in Chapter 29 note (a) fall under prepared chemical mixtures.
If formulated as diammonium adipate fertilizer
Salts of organic acids like diammonium adipate are classified under fertilizers when used for agricultural purposes (Chapter 31).

Import Tips & Compliance
• Verify purity exceeds 99% to avoid reclassification as mixtures under Chapter 38; provide REACH/SDS documentation for hazardous material handling
• Common pitfall: incorrect labeling as 'nylon intermediate' shifts to parts classification
