This code covers the named nitrogen-only heterocyclic compounds indole, 3-methylindole (skatole), 6-allyl-6,7-dihydro-5H-dibenz[c,e]azepine (azapetine), phenindamine and their salts, as well as imipramine hydrochloride. The product must be one of these specifically named substances or a salt of the named substances.

Before you use the code
The code can be right while what you pay still changes, because of where the goods come from, when they arrive, or extra EU measures.
2933 99 20 00
When these goods are imported into the EU, the declaration uses the 10-digit form 2933992000: this code with 00 added. There is no further split under it.
Exports from the EU and Intrastat normally use the 8-digit code as it is.
EU tariff data of Sept. 13, 2026.
Rates, origin and documents
Besides the ordinary duty, the EU records these kinds of measure against this code. They are listed as signals only: whether one applies to your goods can depend on where they come from, who produced them, the exact product and the documents you present. No amounts are worked out here.
Data of Sept. 1, 2026
Preferential rates exist for goods originating in:
These rates apply to Economic Partnership Agreements; CARIFORUM except Haiti; GSP-EBA (Special arrangement for the least-developed countries - Everything But Arms); OCTs (Overseas Countries and Territories); GSP+ (incentive arrangement for sustainable development and good governance).
Whether you can use one depends on the origin rules for the goods and on the documentation you can show.
Check this code in the official EU TARIC databaseImport restrictions are recorded for goods originating in:
The EU records document conditions on this code. What customs may ask for depends on where the goods come from, exactly what the product is and the customs procedure.
Proof of origin 2 conditions
If you claim a lower rate for goods from a country the EU has a trade agreement with, customs asks for proof of origin, for example a EUR.1 certificate or an origin declaration.
Sanctions and restricted regions 10 conditions
Some conditions come from EU sanctions rules. They matter when the goods are linked to a country or region the EU restricts trade with.
One last classification check
Use this view if you are still unsure the code describes the product precisely.
Compare the sibling codes at this level before you settle on this one.
Classification decides the rate here: from duty free to 6.5%.
Worth comparing
Codes that sit close to this one, for when the material itself could be different.
That code concerns aromatic monoamines and their derivatives, whereas this code specifically names indole, skatole, azapetine, phenindamine and imipramine hydrochloride.
That code covers other products at this branch and also lists these named substances among its exclusions; this code specifically names indole, skatole, azapetine, phenindamine and imipramine hydrochloride.
That code specifically names thiethylperazine and thioridazine and their salts, not the substances specifically named here.
Duty rates shown here are estimates, read from official EU / Danish, Norwegian and UK tariff data for orientation only. Confirm the current rate with Toldstyrelsen, TARIC, Norwegian Customs or the UK Online Trade Tariff before you file. The rate you pay can also depend on the country of origin. These are base customs duties only: import VAT, excise duties, anti-dumping duties and safeguard or quota measures are not included.
