Norepinephrine Bitartrate
Norepinephrine bitartrate is a synthetic salt form of norepinephrine, a catecholamine hormone essential for treating septic shock and hypotension via vasopressor effects. Classified under HTS 2937.90.2000 as a structural analogue of catecholamine hormones used primarily for hormonal action on adrenergic receptors. It qualifies as a separate chemically defined organic compound per Chapter 29 notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported without specified hormonal grade or for non-medical synthesis
Non-hormone use shifts to amino acid function compounds in heading 2922, as it doesn't meet 'used primarily as hormones' criterion.
If in bulk medicinal form with excipients for compounding
Medicinal norepinephrine mixtures for further processing classify under Chapter 30 as medicaments, not pure hormones.
If for heavily modified derivatives lacking core catecholamine structure
Advanced structural analogues without direct catecholamine hormonal function fall under other amine-function compounds.

Import Tips & Compliance
• Submit DEA documentation if applicable and COA verifying bitartrate salt structure to confirm catecholamine classification
• Declare as pharmaceutical API with proof of >98% purity to prevent misclassification as general chemical
• Watch for oxidation issues; provide stabilizer data and avoid bulk packaging without proper inert atmosphere seals
