Machines for Additive Manufacturing by Metal Deposit

Heading 8485.10 covers machines whose primary function is to build up a metal part by depositing material layer by layer — such as laser powder bed fusion or directed energy deposition systems. Laser cutting and welding machines, which remove or join existing material rather than deposit it, are classified under different headings (typically Chapter 84 or 85 provisions for machine tools or laser apparatus). The additive, layer-by-layer construction process is the defining functional criterion.

Certain metal additive manufacturing systems with advanced capabilities — particularly those capable of producing aerospace or defense-grade components — may be subject to US Export Administration Regulations (EAR) controls on re-export, and some foreign-origin systems may require review under CFIUS or other national-security frameworks. Importers and end users should consult with trade counsel to assess whether specific equipment triggers any licensing or notification obligations.
