HS Code for Mineral wool insulation

Mineral wool insulation is classified under HS code 6806.10. This code specifically covers slag wool, rock wool, and similar mineral wools, including intermixtures thereof, whether they are in bulk, sheets, or rolls. These materials are manufactured by melting furnace slag or natural volcanic rock and then spinning the molten material into fine fibers. The classification is based on the inorganic mineral composition of the fibers and their primary application as thermal or acoustic insulation. Because these products are processed into a fibrous form from mineral bases, they are grouped in Chapter 68, which deals with articles of stone, plaster, cement, or similar materials. This heading is distinct from those covering organic insulation materials like cork or wood fiber.

Products Included

• Rock wool batts for wall insulation
• Slag wool blankets for industrial furnaces
• Mineral wool rolls for attic insulation
• Loose-fill mineral wool for blowing applications
• Acoustic mineral wool panels

Common Misclassification

Mineral wool is most frequently misclassified with glass wool, which falls under HS code 7019. While they look similar and serve the same purpose, glass wool is made from glass fibers and belongs in Chapter 70. Another common confusion occurs with HS code 6806.90, which is a residual category for other mineral materials for heat or sound insulation. However, because 6806.10 specifically names slag and rock wool, it must be used for those specific types. Additionally, if the mineral wool is combined with other materials in a way that it becomes a composite article of another chapter, the classification may change.

FAQ

What is the HS code for mineral wool insulation?

The HS code for mineral wool insulation, including rock and slag wool, is 6806.10.

Is glass wool classified under the same code?

No, glass wool is classified under HS code 7019, as it is considered a product of glass rather than a mineral wool like rock or slag wool.
