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
View full HS code details

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.

Products Included

  • Magnesite-chromite refractory bricks
  • Chrome-magnesite bricks
  • Pure chromite refractory blocks
  • Refractory tiles containing >50% Cr2O3
  • Furnace lining blocks based on chromite

Common Misclassification

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.

FAQ

What is the HS code for chromite bricks?

The HS code for refractory bricks containing more than 50% chromium, magnesium, or calcium oxides is 6902.10.

What defines a brick as \"refractory\" for classification?

A brick is considered refractory if it is designed to resist high temperatures (usually above 1,500 degrees Celsius) and is used for lining furnaces or other high-heat industrial equipment.
