HS-4 · Heading
8457 — Machining centres, unit construction machines (single station) and multi-station transfer machines for working metal
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-4 8457 when importing machinery like machining centers or multi-station transfer machines designed for working with metal. For instance, if you're bringing in a CNC machining center that shapes metal parts, this is the correct code to use.
Choosing the right subheading under HS-4 8457 is crucial. If your machine is a machining center specifically designed for metal, you'll classify it under 845710. However, if it’s a unit construction machine that operates as a single station, then 845720 is the appropriate choice.
The distinction between 845720 and 845730 is based on functionality. If your equipment is a multi-station transfer machine that processes metal parts in multiple steps, it falls under 845730. In contrast, single station machines that handle one operation at a time should be classified under 845720.
