About slag, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag, mixtures and articles of heat, sound insulating or sound-absorbing mineral materials

HS code 6806 covers a diverse range of mineral-based insulation and sound-absorbing materials that play a crucial role in the construction, manufacturing, and energy sectors. These materials, including slag, rock wool, vermiculite, and expanded clays, are valued for their exceptional thermal and acoustic properties, making them indispensable in the quest for energy-efficient and acoustically-optimized buildings, machinery, and industrial processes.

Production process

The production of the materials covered under HS code 6806 typically involves a combination of mining, processing, and manufacturing techniques. Slag, for instance, is a byproduct of metal smelting processes, which is then further processed and expanded to create lightweight, insulating materials. Rock wool is produced by melting and spinning mineral rocks, while vermiculite and expanded clays undergo thermal treatment to create their signature porous and lightweight structures.

Production inputs

The key inputs for the industries covered under HS code 6806 include various types of mineral resources, such as 2530 Mineral substances not elsewhere specified, 2621 (Slag, ash and residues (other than from the manufacture of iron or steel)) and 6806 Slag, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag, mixtures and articles of heat, sound insulating or sound-absorbing mineral materials. Additionally, these industries rely on specialized machinery and equipment for mining, processing, and manufacturing their products.

Production outputs

The outputs of the industries covered under HS code 6806 are primarily used as insulation and sound-absorbing materials in the construction, manufacturing, and energy sectors. These materials are often incorporated into 6808 Panels, boards, tiles, blocks and similar articles of vegetable fiber, of straw or of shavings, chips, particles, sawdust or other waste, of wood, agglomerated with cement, plaster or other mineral binders, 6809 Articles of plaster or of compositions based on plaster, and 6810 Articles of cement, of concrete or of artificial stone, whether or not reinforced, among other applications.
