Last updated: April 2026 dataIndustrial molds — including injection molds, die-casting dies, and compression molds used to shape plastics, rubber, and metals — are precision tooling assets that often represent significant capital investment and are subject to complex valuation rules at US Customs. Molds are frequently manufactured offshore (notably in China, Canada, and Mexico) and imported either as standalone goods or as assists provided to foreign manufacturers, which triggers separate customs valuation and duty implications. Classification under HTS Chapter 84 depends on the mold's intended material — plastic injection molds, glass molds, and metal die-casting dies each fall under distinct subheadings with potentially different duty rates.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
An assist is any item — including molds, dies, or tooling — that a US importer provides free or at reduced cost to a foreign manufacturer for use in producing imported goods. The value of the assist must be added to the transaction value of the finished goods for customs valuation purposes. Failure to declare assists is a common compliance error that can result in penalties and back-duty assessments.
Plastic injection molds are classified under HTS heading 8480 (molding boxes and molds for rubber or plastics), while metal die-casting dies fall under the same heading but in subheadings specific to die-casting. Glass molds and molds for other materials have their own subheadings within 8480. The correct subheading depends on the material the mold is designed to process, not the material the mold itself is made from.
