Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-blended into fuel or oil additive compositions
Antioxidant preparations containing predominantly petroleum oils classify under Chapter 38 as additive compositions rather than pure phenols.
If monophenols like cresols rather than polyphenols
Single-ring phenols without multiple phenolic groups fall under earlier 2907 subheadings, changing classification within the chapter.
If containing sulfur directly linked to carbon
Organo-sulfur compounds are classified in 2930 even if phenolic, per specific Chapter 29 notes on organo-inorganic priorities.

Food-Grade TBHQ (tert-Butylhydroquinone) Crystals
Food-grade TBHQ crystals are a highly purified form of tert-Butylhydroquinone approved by FDA for use as an antioxidant in edible oils, shortenings, and baked goods at levels up to 0.02%. This polyphenolic compound is specifically enumerated under HTS 2907.29.25.00 due to its chemical structure as a tert-butyl substituted hydroquinone. It prevents rancidity and extends shelf life in lipid-containing foods.
Pharmaceutical-Grade tert-Butylhydroquinone
Pharmaceutical-grade TBHQ is a USP-compliant polyphenolic antioxidant used in drug formulations to protect active ingredients from oxidation, particularly in topical creams and injectables. It matches HTS 2907.29.25.00 as a specifically named polyphenol; phenol-alcohol derivative. High purity ensures stability in sensitive medicinal products.
Cosmetic TBHQ Antioxidant Pellets
TBHQ pellets formulated for cosmetics act as a lipid peroxidation inhibitor in creams, lotions, and lip products, maintaining product integrity against atmospheric oxygen.
