Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If impurities exceed 5% or contains anti-caking agent
Chapter note (f) stabilizers push to preparations if not 'necessary for preservation' only.
If classified among other chlorinated phenolic acids
Specific naming prevails, but similar chlorosalicylics might group differently.

Import Tips & Compliance
• Submit impurity profile in CoA; exceeds 2% impurities risks reclassification to mixtures
• Check for anti-dumping duties from specific origins; common for halogenated aromatics from Asia
• Declare as 'not for human consumption' to avoid FDA scrutiny

4,4-Bis(4-hydroxyphenyl) pentanoic acid
This is a specific carboxylic acid with phenol function, explicitly named in HTS 2918.29.3900. It features two 4-hydroxyphenyl groups attached to the 4-position of pentanoic acid, classifying it under carboxylic acids with phenol function but without other oxygen functions. Used primarily as a pharmaceutical intermediate.
3,5,6-Trichlorosalicylic acid
A halogenated derivative of salicylic acid, specifically listed under HTS 2918.29.3900 as a carboxylic acid with phenol function. The trichloro substitution on the aromatic ring qualifies it under halogenated phenolic carboxylic acids without other oxygen functions. Commonly used in dye synthesis and pharmaceutical intermediates.
Bisphenol A bis(4-hydroxyphenyl)propane derivative acid
A structural analog of 4,4-bis(4-hydroxyphenyl)pentanoic acid used in polymer synthesis, classified under the specific naming in HTS 2918.29.3900. It maintains the phenolic carboxylic acid structure without additional oxygen functions. Applied in specialty resin production.
4,4-Bis(4-hydroxyphenyl)pentanoic acid stabilized crystals
Crystalline form of 4,4-bis(4-hydroxyphenyl)pentanoic acid with added stabilizer for transport, classified under HTS 2918.29.3900 per chapter note (f). The stabilizer prevents degradation without altering use suitability.
