Product classification
HS code for Isosafrole: 2932.91
Heterocyclic compounds, with oxygen hetero-atom(s) only, (other than lactones or compounds containing an unfused furan ring (whether or not hydrogenated) in the structure), isosafrole.
Classification of isosafrole under HS 2932.91
Isosafrole is classified under HS code 293291. This classification falls within Chapter 29, which deals with organic chemicals, and specifically under heading 2932, which covers heterocyclic compounds with oxygen hetero-atom(s) only. Subheading 293291 is a specific designation for isosafrole. Isosafrole is an organic compound that is an isomer of safrole and is used in the fragrance industry and as a precursor in the synthesis of other chemicals. Because it is a precursor chemical used in the manufacture of certain controlled substances, its classification is strictly monitored. The code 293291 is used for the chemical in its isolated, chemically defined form. The presence of the heterocyclic ring structure containing oxygen is the primary reason for its placement under heading 2932. Accurate classification is vital for international monitoring and adherence to conventions regarding chemical precursors. Importers and exporters must ensure that the chemical purity meets the requirements for Chapter 29 and that all necessary permits for precursor chemicals are in place alongside the HS declaration.

Codes often confused with 2932.91
Common mistake. Isosafrole is often confused with its isomer, safrole, which is classified under HS code 293294. It may also be misclassified under HS code 3301 if it is a component of an essential oil that has not been isolated. Another potential error is classification under 293292, which is reserved for 1-(1,3-Benzodioxol-5-yl)propan-2-one.
Top exporters and importers of HS 293291 (the code used for isosafrole), 2025
In 2025, the largest exporter of HS 293291 (the code used for isosafrole) in UN Comtrade data was the United States, with 52% of world exports; the largest importer in UN Comtrade data was Egypt, with 69% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about isosafrole
What is the HS code for Isosafrole?
The HS code for Isosafrole is 293291 (Heterocyclic compounds; with oxygen hetero-atom(s) only, (other than lactones or compounds containing an unfused furan ring (whether or not hydrogenated) in the structure), isosafrole). The specific HS code for isosafrole is 293291.
How do I classify Isosafrole for customs?
Isosafrole is classified under HS code 293291 — Heterocyclic compounds; with oxygen hetero-atom(s) only, (other than lactones or compounds containing an unfused furan ring (whether or not hydrogenated) in the structure), isosafrole. This is a 6-digit subheading level code.
Why is isosafrole classified as a heterocyclic compound?
