HS Code for Mold base

A mold base is classified under HS code 8480.20. This classification is part of the broader heading 8480, which covers molding boxes for metal foundry, mold bases, molding patterns, and molds for metal, glass, mineral materials, rubber, or plastics. The mold base is the fundamental supporting structure of a mold assembly, providing the housing for the mold cores, cavities, and other components like ejector pins and cooling channels. It is classified here because it is a specialized component designed specifically for the molding process. According to the Section XVI notes and Chapter 84 definitions, these bases are considered essential parts of the molding equipment. The classification applies regardless of whether the base is made of steel, aluminum, or other metals, provided it is intended for use with the materials specified in the heading description (metal, glass, rubber, or plastics).

Products Included

• Aluminum mold bases for injection molding
• Die sets for metal casting
• Precision machined mold plates
• Ejector housings for mold assemblies

Common Misclassification

Mold bases are often misclassified under HS code 8480.71 or 8480.79, which are the codes for the complete molds for plastics or rubber. While the base is part of the mold, 8480.20 is the specific subheading for the base alone. Another common error is classifying them under 7326.90 as 'other articles of iron or steel.' However, because the mold base is a clearly identifiable part of a machine tool accessory described in heading 8480, the more specific code must be used per GRI 3(a).
