Nonferrous Metal Die-Casting Foundries

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.
