Product classification
HS code for Mineral wool insulation: 6806.10
Slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls.
Classification of mineral wool insulation under HS 6806.10
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.

Codes often confused with 6806.10
Common mistake. 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.

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).
