Excluding high-purity material with aluminium oxide content of at least 98.5% by weight
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 artificial corundum, whether or not chemically defined, where less than 50% of the total weight has a particle size larger than 10 mm. It excludes material with an aluminium oxide content of at least 98.5% by weight, described as high-purity material.

Official tariff text

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
5 import lines
When these goods are imported into the EU, the declaration needs a 10-digit code. Under 2818 10 91 the EU tariff has 5 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.
The standard duty rate is the same on every line.

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

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).

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 11 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 1 condition
Depending on the exact product, customs may ask for a licence, a permit or a control certificate before the goods are released.
Other conditions 3 conditions
These conditions match none of the groups above. Whether customs asks for one depends on the goods, where they come from and the customs procedure.

Worth comparing
Codes that sit close to this one, for when the material itself could be different.
Both titles specify less than 50% of the total weight in particles larger than 10 mm, but this code excludes aluminium oxide content of at least 98.5% by weight, while 2818 10 11 states the opposite aluminium oxide exception.
2818 10 19 covers at least 50% of the total weight in particles larger than 10 mm, whereas this code covers less than 50%.
2818 10 99 covers at least 50% of the total weight in particles larger than 10 mm and has the aluminium oxide exception for at least 98.5% by weight; this code specifies less than 50%.
