Last updated: September 2026 dataTetracyclines are broad-spectrum antibiotics widely used in human medicine, veterinary applications, and aquaculture, and all imports as drug substances fall under FDA oversight for cGMP compliance and facility registration. The entire heading is captured under a single 10-digit line (2941300000), meaning classification disputes typically arise at the chapter level rather than within the heading. China and Switzerland lead US supply, with Germany also a notable source — a supplier mix that reflects both large-scale API fermentation capacity and high-purity synthetic derivative manufacturing. Chinese-origin tetracycline APIs may be subject to Section 301 tariff measures.

Yes, semi-synthetic derivatives including doxycycline and minocycline are classified under 294130 as tetracycline derivatives, provided they retain the tetracycline core structure. Importers should confirm the specific chemical identity with a licensed customs broker, as some highly modified compounds may be reclassified elsewhere in Chapter 29.
A commercial shipment generally requires an FDA Prior Notice (if the substance may be used in food-contact or veterinary contexts), a certificate of analysis, and evidence of the exporting facility's FDA registration. Drug substance shipments may also require an import alert check to confirm the facility is not on detention-without-physical-examination status.
