It falls under tariff item 2918.29.00 as an 'other' carboxylic acid with phenol function, not more specifically covered elsewhere in the chapter. It is commonly used as an intermediate in the synthesis of dyes and pharmaceuticals.
1-Hydroxy-2-Naphthoic Acid Phenyl Ester
1-Hydroxy-2-naphthoic acid phenyl ester is the phenyl ester derivative of the parent acid, classified with the acid per Chapter 29 ester rules. It retains the phenolic and carboxylic functions and is used in fine chemical synthesis. It falls under tariff item 2918.29.00 as an 'other' product of this subheading.
2,3-Cresotic Acid
2,3-Cresotic acid (2,3-dihydroxy-4-methylbenzoic acid) is a carboxylic acid with a phenol function, classified under tariff item 2918.29.00 as an 'other' product. It is a chemically defined compound used in organic synthesis and pharmaceutical intermediates. The presence of a methyl group does not remove it from this subheading.
2-Hydroxy-1-Naphthoic Acid
2-Hydroxy-1-naphthoic acid is a phenolic naphthoic acid with a carboxylic acid group and a hydroxyl group on adjacent positions. It is classified under tariff item 2918.29.00 as an 'other' carboxylic acid with phenol function. It is widely used in the synthesis of azo dyes and pharmaceutical intermediates.
2-Hydroxybenzoic Acid Calcium Salt
2-Hydroxybenzoic acid calcium salt (calcium salicylate) is the calcium salt of salicylic acid, classified with the parent acid under Chapter 29 salt rules. It falls under tariff item 2918.29.00 as an 'other' carboxylic acid with phenol function. It is used in pharmaceutical and cosmetic applications.
