HS Code for Foundry pattern

Foundry patterns are classified under HS code 8480.30. Heading 8480 is dedicated to moulding boxes for metal foundry, moulding bases, moulding patterns, and moulds for metal, metal carbides, glass, mineral materials, rubber, or plastics. A foundry pattern is a physical model used to form the cavity in a sand mould into which molten metal will be poured. The classification under 8480.30 is based on the item's function as a template for the moulding process. Regardless of whether the pattern is made of wood, plastic, or metal, it is classified here because the Harmonized System prioritizes the specific use of the item in the foundry process over the constituent material of the pattern itself. This follows the principle of specific heading over general material headings (GRI 3a). These patterns are essential for ensuring the dimensional accuracy of the final cast part and are often precision-engineered to account for metal shrinkage during cooling.

Products Included

• Wooden foundry patterns
• Aluminum or iron moulding patterns
• Plastic and epoxy resin patterns
• Split patterns and match-plate patterns
• Gated patterns for multiple castings
• Lost foam patterns (if reusable or part of a set)

Common Misclassification

Foundry patterns are often misclassified based on their material. For example, wooden patterns might be incorrectly placed under 4421 (other articles of wood), or plastic patterns under 3926 (other articles of plastic). However, HS code 8480.30 is the specific provision for patterns regardless of material. Another common confusion is with the moulds themselves (8480.41 for metal moulds), but the pattern is the "positive" model used to create the "negative" space in the sand, not the final mould that receives the liquid metal.

FAQ

What is the HS code for Foundry pattern?

The HS code for a foundry moulding pattern is 8480.30.

Does the material of the pattern change the HS code?

No, whether the pattern is made of wood, metal, or plastic, it remains under 8480.30 because the HS code is based on its specific function in the foundry process.
