Last updated: August 2026 dataNorephedrine — also known in some trade contexts as phenylpropanolamine (PPA) — in finished-dose medicament form is classified under tariff line 3004430000, the sole US 10-digit line within this heading. FDA withdrew approval for PPA-containing OTC drug products in the US market in 2000 due to hemorrhagic stroke risk, making importation of such products for domestic retail sale highly restricted; importers should verify current FDA status before attempting entry. DEA also lists norephedrine as a regulated chemical precursor, adding a separate layer of import controls. Classification in this heading rather than 300441 or 300442 requires that norephedrine or its salts be the relevant active alkaloid.

FDA's 2000 voluntary market withdrawal of phenylpropanolamine (PPA) products significantly restricts domestic retail sale. Importers must confirm that any specific formulation holds current FDA approval or an applicable exemption before entry. Shipments lacking FDA authorization are subject to refusal of admission. Consult a licensed customs broker and FDA regulatory counsel before importing.
Norephedrine is a DEA-listed chemical precursor, so importers must obtain DEA import authorization and comply with quota requirements, mirroring the process for ephedrine and pseudoephedrine. This dual FDA/DEA oversight makes the compliance burden for 300443 comparable to the other ephedrine-family headings, even though the commercial market for these products in the US is very limited.
