SITCSection 5
U.S. imports of coumarin, methylcoumarins, and ethylcoumarins (SITC 51562) totaled $671K in July 2026, traded with 9 countries.
Importers of Coumarin, Methylcoumarins, and Ethylcoumarins paid $81K in duties in July 2026 — an effective duty rate of 15% on $527K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataCoumarin and its methyl and ethyl homologs are lactone-based aromatic compounds prized for their characteristic sweet, hay-like fragrance, historically used in perfumery and flavor applications. Regulatory restrictions on coumarin's use in food products — stemming from hepatotoxicity concerns — have shifted commercial demand toward fragrance and cosmetic applications, where it remains a widely used ingredient subject to concentration limits set by bodies such as the International Fragrance Association (IFRA). Importers should confirm that product specifications align with the intended end-use, as food-grade and fragrance-grade material face different regulatory scrutiny.

Regulatory agencies in the US and EU have restricted coumarin as a direct food additive due to potential liver toxicity at elevated doses. However, at the low concentrations typical in fine fragrances and cosmetics, it remains permitted subject to IFRA guidelines and, in the EU, mandatory labeling thresholds. Importers should clearly document the intended end-use to ensure the correct regulatory pathway.
Methyl and ethyl substitution alters the odor profile and intensity of the base coumarin structure, making these homologs useful for fine-tuning fragrance formulations. For classification purposes, all three types fall within the same SITC heading, but importers should provide the specific CAS number and structural description to support accurate tariff line assignment at the HTS level.
