Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic polycarboxylic acid instead
Adipic acid is acyclic; aromatic versions like terephthalic acid use different subheading.
If technical grade with impurities
Non-chemically defined mixtures exclude from Chapter 29 per note (a).
If as mineral fertilizer additive
When used agriculturally, organic acid salts shift to Chapter 31 fertilizers.

Import Tips & Compliance
• Confirm flake moisture content <0.3% to prevent caking; use anti-dusting bags
• Common error: classifying as nylon salt (5402) prematurely
