HS Code for Mineral insulation

Mineral insulation products are classified under HS code 6806.90. This code encompasses mixtures and articles of heat-insulating, sound-insulating, or sound-absorbing mineral materials. The classification is determined by the composition of the material, which typically involves mineral wools such as slag or rock wool or expanded minerals like perlite or vermiculite. Under the Harmonized System, Chapter 68 covers articles of stone and other mineral substances. Heading 6806 is specifically designed for products that provide insulation through their mineral structure. Subheading 6806.90 is the residual category for articles made from these materials that are not specifically listed as slag wool or expanded minerals in their bulk form. This includes finished products like pipe coverings, acoustic panels, and specialized industrial insulation blocks. It is essential that these products do not contain asbestos, as those would be classified under heading 6812. The classification also excludes ceramic products of Chapter 69, which are fired after shaping.

Products Included

• Rock wool insulation boards
• Slag wool batts
• Expanded perlite blocks
• Exfoliated vermiculite panels
• Acoustic mineral fiber ceiling tiles
• Mineral-based pipe insulation sleeves

Common Misclassification

The most common misclassification is with HS code 7019, which covers glass wool and fiberglass insulation. While they look similar, glass fiber is classified in Chapter 70. Another confusion occurs with 6901.00, which covers bricks and blocks of fossil meals like kieselguhr, which are fired ceramic goods.
