HS Code 6806.10 – Slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls
HS code 6806.10 is the 6-digit subheading for slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls. It is used for rock wool insulation boards, slag wool blankets, mineral wool rolls, acoustic mineral wool panels and fire-rated mineral wool slabs.
What HS 6806.10 covers
This HS code encompasses various forms of mineral wools, primarily slag wool and rock wool, which are highly valued in international trade for their exceptional thermal and acoustic insulation properties. These materials are manufactured by melting natural rocks (like basalt or diabase) or industrial by-products (like blast furnace slag) and spinning them into fine fibers. Major importers are countries with active construction industries, particularly those focused on energy efficiency and fire safety in buildings, such as European nations, the USA, and Canada. Exporters often include countries with significant industrial output and access to raw materials, like China, Germany, and Scandinavian countries. The trade is driven by global demand for sustainable building practices, energy conservation, and stringent fire safety regulations, making these mineral wools critical components in modern construction and industrial insulation applications.

Codes often confused with 6806.10
Common mistake. This code is distinct from other insulating materials like glass wool (7019) or asbestos-based products (6812), as it specifically covers slag and rock wools. It could be confused with 680690 if the form is not clearly bulk, sheets, or rolls, but rather a more complex article.
Top exporters and importers of HS code 680610, 2025
In 2025, the largest exporter of HS code 680610 in UN Comtrade data was Poland, with 16% of world exports; the largest importer in UN Comtrade data was Germany, with 8.4% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
