U.S. imports of propylene glycol (propane-1,2-diol) (HS 290532) totaled $7.8M in April 2026, traded with 17 countries.
Importers of Propylene Glycol (Propane-1,2-Diol) paid $1.2M in duties in April 2026 — an effective duty rate of 16% on $7.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPropylene glycol's FDA GRAS status makes it uniquely versatile — it serves simultaneously as a food additive, pharmaceutical excipient, cosmetic humectant, and industrial solvent, all under a single HTS line (2905320000). South Korea and Thailand are the leading US suppliers, with Germany also a notable source, reflecting both Asian petrochemical export capacity and European specialty-grade production. Unlike ethylene glycol, propylene glycol is generally recognized as safe for food and pharmaceutical contact, but importers supplying those end-use markets should maintain documentation of food- or USP-grade compliance. Section 301 tariff exposure applies to shipments originating from China.

For pharmaceutical use, suppliers should provide a Certificate of Analysis confirming compliance with USP/EP monograph specifications, including purity, water content, and absence of ethylene glycol contamination. For food applications, the product should meet FCC (Food Chemicals Codex) grade standards. FDA may inspect food-contact chemical shipments, so maintaining full traceability documentation from the foreign manufacturer is strongly recommended.
Propylene glycol (propane-1,2-diol) is a diol and classifies under heading 2905.32. Dipropylene glycol, a mixture of isomeric propylene glycol dimers, is an ether-alcohol and classifies under a different chapter 29 heading. Importers should confirm the exact chemical identity with the supplier's certificate of analysis before filing entry, as misclassification between these closely related compounds is a common audit finding.
