Last updated: April 2026 dataMolding patterns are the physical replicas — typically machined from wood, metal, plastic, or foam — used to form the cavity impression in foundry sand or investment casting molds, and they sit at the front end of the casting tooling supply chain. Canada is the leading US supplier under this heading, with Japan and China also significant sources; Canadian-origin patterns meeting USMCA rules of origin may qualify for preferential treatment. Because patterns are often custom-engineered to a buyer's proprietary part geometry, commercial invoices should clearly describe the substrate material and the casting process for which the pattern is intended, as these details support correct classification and assist in valuation review.

Custom molding patterns are generally valued at transaction value — the price actually paid or payable — under 19 USC 1401a. If the US buyer provided design specifications, tooling assists, or engineering support to the foreign manufacturer, the value of those assists may need to be added to the declared customs value. Importers should document any assists and disclose them on the entry.
No — heading 8480.30 covers molding patterns regardless of the material from which they are made. The classification is function-driven: if the article serves as the master form used to create a mold cavity in a casting process, it classifies here irrespective of whether it is machined aluminum, epoxy resin, or wood.
