Products classified under HTS 2918.29.20.00
Gentisic Acid USP Grade
Gentisic acid (2,5-dihydroxybenzoic acid) is a chemically defined organic compound with a carboxylic acid group and phenolic hydroxy functions, classified under HTS 2918.29.2000 as a specific carboxylic acid with phenol function but without other oxygen function. It is supplied as a white crystalline powder for pharmaceutical and research applications.
Ferulic Acid Powder 99%
Ferulic acid (4-hydroxy-3-methoxycinnamic acid) is a hydroxycinnamic acid classified under HTS 2918.29.2000 as its salts are specifically named, with the pure acid following the same principal function. Used as antioxidant in cosmetics and food supplements, it's a white to off-white powder.
Caffeic Acid Pharmaceutical Grade
Caffeic acid (3,4-dihydroxycinnamic acid), a hydroxycinnamic acid and its salts, falls under HTS 2918.29.2000 due to its phenolic carboxylic acid structure without other oxygen functions. Supplied as high-purity powder for drug synthesis and antioxidant applications.
