U.S. imports of Nonferrous Metal Die-Casting Foundries (NAICS 331523) totaled $8.3M in August 2026, imported from 41 countries.
Importers of Nonferrous Metal Die-Casting Foundries paid $5.0M in duties in August 2026, an average duty rate of 61.32% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataHigh-pressure die casting of zinc, aluminum, magnesium, and copper alloys into net-shape or near-net-shape components defines NAICS 331523, with automotive parts — transmission cases, engine brackets, door handles — representing the dominant end market. Die casting's combination of high throughput, dimensional repeatability, and thin-wall capability makes it the preferred process for mass-produced metal components, and the segment is deeply integrated into global automotive supply chains. Importers of die-cast parts should be aware that aluminum die castings from certain countries have been subject to antidumping scrutiny, and that automotive-grade castings typically require IATF 16949 quality certification from the supplying foundry.

655 import shipments a month
For automotive applications, IATF 16949 (the automotive quality management standard) is the baseline expectation, often supplemented by customer-specific requirements (CSRs) from OEMs. For aerospace or defense die castings, AS9100 or NADCAP process approvals may be required. Beyond quality systems, importers should request dimensional inspection reports, alloy chemistry certifications (to ASTM or equivalent standards), and, where applicable, RoHS or REACH compliance declarations for restricted substances in the alloy.
Aluminum alloys (particularly A380 and A383) account for the largest share of die-cast production by weight, followed by zinc alloys (Zamak series) and, to a lesser extent, magnesium and copper alloys. Alloy composition directly affects HTS classification: aluminum die castings fall under Chapter 76 provisions for aluminum articles, zinc die castings under Chapter 79, and magnesium die castings under Chapter 81 — each with potentially different duty rates and trade-remedy exposure. Correct alloy identification on entry documents is essential.
