Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing other oxygen functions beyond alcohol/carboxyl
Heading 2918.19 covers carboxylic acids with additional oxygen functions not specified elsewhere.
If already incorporated into finished food products like candy
Finished food preparations classify in chapter 21, not pure chemicals.
If stabilized with anticaking agents exceeding transport needs
Additives rendering specific use may exclude from chapter 29 per note 1(g).

Import Tips & Compliance
• Obtain USP/EP certificate; FDA requires GRAS affirmation for food contact
• Label with CAS 87-69-4 and purity >99.7%; mislabeling risks seizure
• For baking powders, ensure not pre-mixed with bicarbonate (shifts to 2836)
