Including hydrogenated compounds
This is a complete 8-digit customs code. Exports and Intrastat use it as it is. For an import into the EU, pick a 10-digit line below.
This code covers heterocyclic compounds whose only heteroatoms are nitrogen and whose structure contains a non-fused triazine ring. It includes hydrogenated compounds, but not melamine, atrazine, propazine, simazine, hexogen, methenamine or the specifically named antioxidant compound.
Official tariff text
Heterocyclic compounds with nitrogen hetero-atom[s] only, containing an unfused triazine ring, whether or not hydrogenated, in the structure (excl. melamine, atrazine "ISO", propazine "ISO", simazine "ISO", hexahydro-1,3,5-trinitro-1,3,5-triazine "hexogen, trimethylenetrinitramine", methenamine [INN] "hexamethylenetetramine" and 2,6-di-tert-butyl-4-[4,6-bis"octylthio"-1,3,5-triazine-2-ylamino]phenol)

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.
On an EU import declaration
18 import lines
When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2933 69 80 the EU tariff has 18 lines, each with its own wording.
You or your customs agent pick the line whose wording fits the goods; the last line, "Other", covers what none of the specific wordings describe.
Some lines depend on what the goods will be used for and need customs authorisation; matching the wording alone does not give a lower rate.

A suspension is a lower rate the EU grants for specific products; whether your goods qualify depends on the line's wording and conditions.
Exports from the EU and Intrastat normally use the 8-digit code as it is.

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
Trade-defence measures, such as anti-dumping duty, may apply to goods originating in:
The duty depends on the producer or exporter, so two shipments of the same goods can be charged differently.
This is recorded on a more detailed code below this one, so it may not cover your goods. See the import lines under this code
Check this code in the official EU TARIC databasePreferential 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 13 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.
Product controls and permits 3 conditions
Depending on the exact product, customs may ask for a licence, a permit or a control certificate before the goods are released.
Statements that the goods are outside a rule's scope 1 condition
Some conditions are statements that a rule does not cover the goods, for example that the product is not on a controlled list.

Worth comparing
Codes that sit close to this one, for when the material itself could be different.
That code concerns heterocyclic compounds with only oxygen as heteroatoms, whereas this code concerns compounds with only nitrogen as heteroatoms.
That code names atrazine, propazine, simazine and hexogen; this code covers other compounds in the same non-fused triazine-ring group.
That code names methenamine and one specifically named antioxidant compound; this code covers other compounds in the group.
