HS Code for Die base

A die base, also referred to as a mould base, is classified under HS code 8480.20. Heading 8480 of the Harmonized System covers moulding boxes for metal foundry, mould bases, and various types of moulds for metal, metal carbides, glass, mineral materials, rubber, or plastics. The die base is the essential structural assembly that supports the mould cavity and provides the necessary alignment for the die components during the manufacturing process. According to the Explanatory Notes to the HS, mould bases are the plates and frames that house the internal parts of a mould. Because the die base is a specialized component designed specifically for the assembly of moulds, it is classified under the dedicated subheading 8480.20 rather than as general articles of steel or as parts of specific machinery. This classification applies to bases used in injection moulding, compression moulding, and die casting.

Common Misclassification

Die bases are frequently misclassified under HS code 7326.90, which is a residual category for other articles of iron or steel. This occurs because the base often appears to be a simple assembly of steel plates. However, since it is a specific component of a mould assembly, heading 8480 takes precedence. It is also sometimes confused with HS code 8480.71 or 8480.79, which are the codes for the finished moulds for plastics or rubber, rather than just the base assembly.

FAQ

What is the HS code for Die base?

The HS code for a die base is 8480.20, which specifically covers mould bases for various industrial applications.

Does a die base include the internal cavities?

Generally, no. The die base refers to the supporting frame and plates. If the internal cavities are included and the unit is functional, it may be classified as a complete mould under other subheadings of 8480.
