HS code for Chromite bricks: 6902.10

Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, containing by weight, singly or together, more than 50% of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2o3.

Classification of chromite bricks under HS 6902.10

Chromite bricks are classified under HS code 6902.10. Chapter 69 covers ceramic products, and heading 6902 is dedicated to refractory bricks, blocks, tiles, and similar refractory ceramic constructional goods. The subheading 6902.10 is specifically for products containing, by weight, more than 50% of the elements magnesium (Mg), calcium (Ca), or chromium (Cr), expressed as MgO, CaO, or Cr2O3. These materials are essential for high-temperature industrial applications, such as lining furnaces, kilns, and ovens, due to their ability to withstand thermal stress and chemical erosion. The classification is determined by the refractory nature of the product (ability to withstand temperatures above 1,500°C) and its specific chemical composition dominated by chromium or magnesium oxides.

Codes often confused with 6902.10

Common mistake. These bricks are sometimes confused with HS code 6901.00, which covers bricks made of siliceous fossil meals (like kieselguhr), or 6903, which covers other refractory ceramic goods like retorts and crucibles. The distinction lies in the shape and use; 6902 is for constructional goods (bricks/tiles), while 6903 is for laboratory or specialized industrial equipment. Additionally, non-refractory bricks are classified under 6904, but chromite-based bricks are almost exclusively refractory in nature. Misclassification also occurs with 6806 if the material is considered a mineral wool or expanded mineral, but the fired ceramic nature of chromite bricks mandates Chapter 69.

Top exporters and importers of HS 690210 (the code used for chromite bricks), 2025

In 2025, the largest exporter of HS 690210 (the code used for chromite bricks) in UN Comtrade data was China, with 51% of world exports; the largest importer in UN Comtrade data was the United States, with 7.7% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

Figures cover everything classified under HS 690210, not only chromite bricks.

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 chromite bricks

What is the HS code for Chromite bricks?

The HS code for Chromite bricks is 690210 (Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; containing by weight, singly or together, more than 50% of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2o3). The HS code for refractory bricks containing more than 50% chromium, magnesium, or calcium oxides is 6902.10.

How do I classify Chromite bricks for customs?

Chromite bricks is classified under HS code 690210 — Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; containing by weight, singly or together, more than 50% of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2o3. This is a 6-digit subheading level code.
