HS Code for Andalusite

Andalusite, a nesosilicate mineral composed of aluminium nesosilicate (Al₂SiO₅), is classified under Harmonized System (HS) code 250850. This classification is appropriate because the HS description for this code explicitly includes "andalusite, kyanite and sillimanite, whether or not calcined," alongside various types of clays. Andalusite is a naturally occurring mineral primarily valued for its high alumina content and excellent refractory properties, making it a crucial raw material in industries requiring high-temperature resistance. Its inclusion in this heading reflects its status as a natural mineral product, often traded in its raw or simply calcined form, distinguishing it from more processed or manufactured ceramic materials.

Products Included

• Raw andalusite
• Calcined andalusite
• Kyanite (whether or not calcined)
• Sillimanite (whether or not calcined)
• Various types of clays (excluding expanded clays of heading 6806)

Common Misclassification

Andalusite is sometimes confused with other mineral products or processed materials. One common misclassification involves HS 261790, which covers "Other ores and concentrates of base metals, n.e.c." While andalusite is a mineral, it is not typically considered an ore for base metal extraction; its primary industrial application is in refractory materials and ceramics. Another area of potential confusion is with HS 6806, specifically "expanded clays." The description for 250850 explicitly excludes "expanded clays of heading no. 6806," highlighting that while some clays are covered, those that have undergone expansion processes are classified elsewhere. Andalusite itself is not an expanded material, reinforcing its placement in 250850.

FAQ

What is the HS code for Andalusite?

The HS code for Andalusite is 250850. This code specifically covers andalusite, kyanite, and sillimanite, whether or not calcined, along with certain clays.

What are the primary industrial uses of Andalusite?

Andalusite is primarily used in the production of high-performance refractory materials, ceramics, and as a raw material for mullite production. Its high alumina content and thermal stability make it ideal for applications requiring resistance to extreme temperatures and chemical attack, such as in kilns, furnaces, and foundries.
