Papaverine Hydrobromide Powder
Papaverine hydrobromide is a bromide salt of the opium alkaloid papaverine, utilized in pharmaceutical manufacturing for its antispasmodic properties. Classified under HTS 2939.19.10.00 as a salt of papaverine per the alkaloid heading structure. It is typically imported as a bulk fine chemical for further processing into vascular smooth muscle relaxants.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If noscapine or its salts instead
Other opium alkaloid salts like noscapine have separate statistical suffixes within the same 'other' category.
If diluted in solvents for safety/transport
Solutions of chapter 29 compounds in solvents qualify under note (e) but may shift to mixtures if solvent renders specific use suitability.
If misidentified as a synthetic benzyl alcohol derivative
Papaverine’s core structure might be confused with hydroxylated aromatics, but opium alkaloid specificity prevails in 2939.

Import Tips & Compliance
• Provide detailed salt composition analysis; hydrobromide forms require bromide content verification to distinguish from hydrochloride
• Ensure compliance with DEA precursor chemical regulations if applicable; include end-use statement for legitimate pharmaceutical purposes
• Avoid bulk packaging over 25kg without anti-caking stabilizers, as additions must not alter general use per chapter note (f)
