HS code for Heliotropine: 2932.93
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), piperonal.
Classification of heliotropine under HS 2932.93
Heliotropine, also known as piperonal, is classified under HS code 2932.93. This classification is determined by its chemical structure as a heterocyclic compound containing only oxygen hetero-atoms. Specifically, it belongs to the subcategory of compounds containing an unfused furan ring or, in this case, the specific designation for piperonal within the 2932 heading. The General Rules for the Interpretation (GRI) of the Harmonized System dictate that chemicals are classified based on their molecular structure. Since Heliotropine features a benzodioxole ring system—a heterocyclic structure where oxygen atoms are part of the ring—it is excluded from simpler aldehyde classifications. It is widely used in the fragrance and flavor industries due to its sweet, vanillic, and almond-like scent profile. The classification 2932.93 is precise because it identifies the molecule by its common chemical identity, ensuring that customs authorities can monitor its trade, especially since it is also a precursor chemical in some jurisdictions. The technical nature of this classification requires an understanding of organic chemistry, as the presence of the heterocyclic ring takes precedence over the aldehyde functional group when determining the correct heading under Chapter 29.

Codes often confused with 2932.93
Common mistake. Heliotropine is frequently misclassified under HS code 2912.41 (Vanillin) or 2912.49 (Other aldehyde-ethers). This confusion arises because Heliotropine contains an aldehyde functional group and possesses an aroma similar to vanillin. However, because the oxygen atoms are part of a heterocyclic ring, heading 2932 (Heterocyclic compounds with oxygen hetero-atom(s) only) is more specific than heading 2912 (Aldehydes). According to the hierarchy of the Harmonized System, a compound that can be classified as a heterocyclic compound must be placed in Chapter 2932 rather than under its other functional groups.
Top exporters and importers of HS 293293 (the code used for heliotropine), 2025
In 2025, the largest exporter of HS 293293 (the code used for heliotropine) in UN Comtrade data was China, with 71% of world exports; the largest importer in UN Comtrade data was the United States, with 18% 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 heliotropine
What is the HS code for Heliotropine?
The HS code for Heliotropine is 293293 (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), piperonal). The HS code for Heliotropine (piperonal) is 2932.93.
How do I classify Heliotropine for customs?
Heliotropine is classified under HS code 293293 — 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), piperonal. This is a 6-digit subheading level code.
Is Heliotropine subject to international trade restrictions?
Yes, because Heliotropine is a precursor for certain substances, it may be subject to monitoring under the 1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, requiring specific import/export permits in many countries.
Which countries are the top exporters of heliotropine (HS 293293)?
In 2025, the top exporters of HS 293293 (the code used for heliotropine) in UN Comtrade data were China ($24M, 71% of world exports), Spain ($3.6M) and Germany ($2.3M). World exports came to about $34M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of heliotropine (HS 293293)?
