Products classified under HTS 2939.49.03.00
Ephedrine Hydrochloride
Ephedrine hydrochloride is the hydrochloride salt of ephedrine, a natural alkaloid derived from Ephedra plants, reproduced by synthesis for pharmaceutical use. It falls under HTS 2939.49.0300 as a derivative salt of ephedra alkaloids, used primarily in bronchodilators and nasal decongestants. This classification covers synthetic reproductions meeting chapter 29 criteria for separate chemically defined organic compounds.
Pseudoephedrine Hydrochloride USP
Pseudoephedrine hydrochloride is the USP-grade salt of pseudoephedrine, an ephedra alkaloid stereoisomer synthesized for OTC cold medications. Classified under HTS 2939.49.0300 as an ephedra alkaloid derivative salt per chapter notes allowing synthetic reproductions. Used as a nasal decongestant in products like Sudafed.
Ephedrine Sulfate Powder
Ephedrine sulfate is the sulfuric acid salt of ephedrine alkaloid, synthesized for injectable pharmaceutical applications and asthma treatment. It qualifies under HTS 2939.49.0300 as an ephedra alkaloid salt per chapter classification rules for organic salts. The pure chemical form distinguishes it from formulated drugs.
Phenylpropanolamine Hydrochloride
Phenylpropanolamine HCl is a synthetic ephedrine derivative salt used historically as an appetite suppressant and decongestant. Falls under HTS 2939.49.0300 as an 'other' ephedra alkaloid derivative per the heading's scope for synthetic reproductions. Now restricted but still imported for specific pharmaceutical uses.
Methylephedrine
Methylephedrine is an N-methylated ether derivative of ephedrine, synthesized as a bronchodilator in some Asian markets. Classified in HTS 2939.49.0300 covering ethers and other derivatives of ephedra alkaloids. The modification maintains its classification within the specific ephedra subheading.
