3824.30.00.00 - Nonagglomerated metal carbides mixed together or with metallic binders

This HTS category, 3824.30.00.00, specifically covers nonagglomerated metal carbides that have been mixed together or combined with metallic binders. These materials are characterized by their finely divided particles of metal carbides, such as tungsten carbide, tantalum carbide, or titanium carbide, which are then consolidated with a metal matrix, typically cobalt, nickel, or iron. The key distinction here is the nonagglomerated state of the carbides and the presence of a metallic binder, differentiating them from finished or sintered carbide products.

Compared to its sibling category, 3824.10.00.00, which deals with prepared binders for foundry molds or cores, this classification focuses on the raw materials or semi-finished forms of cermets and similar composite materials rather than their application in the foundry industry. It also differs from other preparations within Chapter 38 by its specific composition of metal carbides and metallic binders, rather than additives for cement or sorbitol.

As this is a leaf node, there are no further subdivisions. Therefore, classification within 3824.30.00.00 relies on verifying the absence of agglomeration and the presence of both nonagglomerated metal carbides and a metallic binder. Importers and exporters should ensure that the material's physical form and composition precisely match these criteria to avoid misclassification.
