Last updated: July 2026 dataHeparin, an anticoagulant derived primarily from porcine intestinal mucosa, is one of the most clinically critical biological drug substances in global trade, and its supply chain drew intense regulatory scrutiny following the 2008 adulteration crisis. The US schedule subdivides the heading into dried liver and glands (3001900110, 3001900115, 3001900150), heparin and its salts (3001900165 and 3001900190), and other human or animal substances (3001900195). India and China are the leading suppliers, with Germany also a significant source; the concentration of porcine mucosa processing in China and India makes supply-chain traceability and FDA facility oversight a persistent compliance priority. Importers should consult a licensed customs broker and confirm FDA registration and cGMP status of the foreign establishment prior to entry.

FDA expects importers to maintain full traceability from the crude heparin source (typically porcine intestinal mucosa) through each processing step to the finished API. Required documentation typically includes certificates of analysis, supplier audit records, and evidence of FDA facility registration for each manufacturing site in the supply chain, consistent with FDA's heparin guidance issued after the 2008 adulteration incident.
The heading's 10-digit lines separate dried or powdered glandular material (3001900110, 3001900115, 3001900150) from heparin and its salts as discrete chemical entities (3001900165, 3001900190). The key distinction is whether the imported material is a processed, characterized drug substance (heparin) or a less-refined dried biological tissue; importers should ensure the certificate of analysis and product description clearly support the claimed line.
