Code 3815 19 90 · Subheading 3815 19

Final code reached

Supported catalysts, excluding precious-metal, nickel and specified fine-grain catalysts

This is a complete 8-digit customs code. There is no further code choice to make below it.

This code covers catalysts on a carrier that do not have a precious metal or precious-metal compound, or nickel or a nickel compound, as the active substance. It also excludes the specified grain catalysts where at least 90% by weight has a size of <= 10 micrometres and the stated magnesium-silicate, copper, bismuth and density conditions apply.

For example

A copper-oxide catalyst on a carrier, with copper as the active substance, not containing a precious metal or nickel as the active substance and not being the specified fine-grain magnesium-silicate catalyst
An iron-oxide catalyst on a carrier, with iron as the active substance, not containing a precious metal or nickel as the active substance and not being the specified fine-grain magnesium-silicate catalyst

Supported catalysts, excluding precious-metal, nickel and specified fine-grain catalysts

The spaces only make the code easier to read. Customs declarations normally use the unspaced form, 38151990.

This is the catch-all under 3815 19: it covers what the sibling codes below do not.

Within supported catalysts, this is the remainder for catalysts not named as precious-metal or nickel catalysts and not matching the specified fine-grain magnesium-silicate catalyst.

Trade measures to be aware of

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.

Lower duty for goods from some countries

Preferential rates exist for goods originating in San Marino; Economic Partnership Agreements; CARIFORUM except Haiti; Comoros (excluding Mayotte), Madagascar, Mauritius, Seychelles and dependencies and Zimbabwe; Botswana, Eswatini, Lesotho, Mozambique and Namibia; GSP-EBA (Special arrangement for the least-developed countries - Everything But Arms); OCTs (Overseas Countries and Territories); Ivory Coast; 52 more origins. Whether you can use one depends on the origin rules for the goods and on the documentation you can show.

A limited quantity at a lower rate

A tariff quota is recorded for this code. This does not say whether any of the quota is still available. It covers goods originating in any country except Belarus and Russian Federation.

This is recorded on a more detailed code below this one, so it may not cover your goods.
