Exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials (including intermixtures thereof)

HS v2017 Code: 680620

About exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials (including intermixtures thereof)

HS code 680620 covers a diverse range of expanded mineral materials, including vermiculite, clays, and slag. These materials play a crucial role in various industries, serving as insulation, absorbents, and lightweight fillers. The production and trade of these expanded mineral materials are integral to the global construction, agriculture, and industrial sectors, contributing to economic growth and sustainable development.

Production process

The production of the materials covered under HS code 680620 typically involves a process of thermal or chemical expansion. Vermiculite, for example, is exfoliated by rapidly heating the mineral, causing it to expand and create a lightweight, porous structure. Similarly, clays and slag can be expanded through controlled heating and processing, resulting in materials with unique properties and applications.

Production inputs

The main inputs required for the production of the materials under HS code 680620 include the raw mineral resources, such as vermiculite, clays, and slag. Additionally, specialized equipment and machinery, as well as energy sources (e.g., electricity, natural gas) are necessary for the thermal or chemical expansion processes. The availability and quality of these raw materials and production resources can significantly impact the industry's output and competitiveness.

Production outputs

The expanded mineral materials produced under HS code 680620 have a wide range of applications. They are commonly used as insulation materials in the construction industry, as absorbents in agriculture and industrial settings, and as lightweight fillers in various products. The outputs of this industry may be consumed by other HS codes, such as 680610 Slag wool, rock wool and similar mineral wools, 690100 Bricks, blocks, tiles and other ceramic goods, and 940600 Prefabricated buildings.
