Last updated: July 2026 dataMolding patterns are the physical templates — made from wood, metal, plastic, or resin — used to form the cavity shape in sand or investment casting molds, and their classification as tooling rather than finished goods is a recurring customs consideration. Pattern complexity ranges from simple split patterns for commodity castings to match-plate and cope-and-drag assemblies for high-volume foundry production. Because patterns are often custom-fabricated to a buyer's design, their transaction value may be subject to assists rules if the US importer provided design specifications or materials to the foreign pattern maker.

If a US importer supplies engineering drawings, CAD files, or other design inputs to a foreign manufacturer producing custom molding patterns, the value of those assists must generally be added to the customs value of the imported patterns. Importers should document the cost of any design work provided and disclose it on the entry to avoid undervaluation penalties.
Patterns are produced in wood, aluminum, cast iron, epoxy resin, and 3D-printed polymers. Material choice affects durability and production volume suitability but does not change the SITC classification, which is based on function. At the HTS level, however, the corresponding subheading may distinguish by material, so importers should confirm the correct 10-digit code with a customs broker.
