Plain-language overview
Use HS-6 250830 when importing or exporting fireclay, a type of clay used primarily in the manufacture of refractory products. For example, a shipment of fireclay bricks intended for high-temperature furnaces falls under this code.
This code specifically covers clays that are not expanded and includes fireclay, which is known for its heat resistance. In contrast, HS-6 250840 covers other types of clays, such as kaolin, which have different properties and uses.
Fireclay is often utilized in industries that require materials that can withstand extreme heat, such as metallurgy and ceramics. If you’re dealing with raw fireclay in bulk for refractory applications, this is the correct classification.
When classifying fireclay, ensure it is not mixed with expanded clays, which are classified under a different heading. This distinction is crucial for accurate customs declarations and tariff applications.
