Products classified under Tariff item 2941.40
Chloramphenicol Acetyl Derivative
> This is an N-acetyl protected intermediate derivative of chloramphenicol, a chemically defined organic compound derived from the parent antibiotic. It is used as a pharmaceutical intermediate in the synthesis of modified antibiotics. Under the Customs Tariff, it qualifies as a derivative of chloramphenicol and is correctly classified under tariff item 2941.40.00.
2941.40.00Chloramphenicol Base Powder
> Pure chloramphenicol base in powdered form, a broad-spectrum antibiotic chemically defined as D-(-)-threo-2,2-dichloro-N-[β-hydroxy-α-(hydroxymethyl)-p-nitrophenethyl]acetamide. It is a separate chemically defined organic compound, meeting the criteria of Chapter 29 Note 1(a). This bulk antibiotic is correctly classified under tariff item 2941.40.00.
2941.40.00Chloramphenicol Eye Ointment Base
> Bulk chloramphenicol powder with a specialized micronized particle size, designated for ophthalmic ointment formulation. It remains a chemically defined antibiotic in bulk form, not a finished preparation. The micronization does not alter its classification as chloramphenicol under tariff item 2941.40.00.
2941.40.00Chloramphenicol Hydrochloride
> Chloramphenicol hydrochloride is a salt form of chloramphenicol, created to enhance aqueous solubility for eye drops and topical formulations. As an inorganic salt of an organic compound, Chapter 29 Note 5(C)(1) directs classification with the parent organic compound. It is correctly classified under tariff item 2941.40.00.
2941.40.00Chloramphenicol Palmitate USP
> Chloramphenicol palmitate is the palmityl ester derivative of chloramphenicol, meeting USP standards for oral suspension preparation. As an ester of an acid-function organic compound with an organic compound, Chapter 29 Note 5(A) classifies it with the compound occurring last in numerical order. It is correctly classified under tariff item 2941.40.00.
2941.40.00Chloramphenicol Research Grade Crystals
> High-purity chloramphenicol crystals (99.5%+) intended for laboratory research and analytical standards. As a separate chemically defined organic compound, it meets Chapter 29 Note 1(a) criteria. Even though not for therapeutic use, it remains chloramphenicol and is classified under tariff item 2941.40.00.
2941.40.00Chloramphenicol Sodium Succinate
