Heading 8457

Machining centers, unit construction machines (single station) and multistation transfer machines, for working metal

12 declarable lines

Heading 8457 covers metal-working machine tools in three groups: machining centers, unit construction machines (single station), and multistation transfer machines. It is split first by machine type, then by used or rebuilt status and automatic tool changer features for machining centers, and by numerical control for the other two groups.

How to choose the right subheading

Decide whether the machine is a machining center, a unit construction machine, or a multistation transfer machine.
For machining centers, check whether the machine is used or rebuilt, then whether it has an automatic tool changer.
For machining centers with automatic tool changers, use spindle orientation and Y-axis travel to pick the line.
For unit construction and multistation transfer machines, check whether the machine is numerically controlled.
Confirm the machine works metal by removing material, not by pressing, rolling, or other forming.

Frequently asked questions

What is the HTS code for a vertical CNC machining center?

For a vertical-spindle machining center with an automatic tool changer and Y-axis travel not over 660 mm, use 8457.10.00.15, general (MFN) 4.2%. If Y-axis travel is over 660 mm, use 8457.10.00.25, general (MFN) 4.2%.

What is the duty on a used machining center?

Used or rebuilt machining centers are classified under 8457.10.00.05, general (MFN) 4.2%.

How do I classify a multistation transfer machine for metal?

If it is numerically controlled, classify it under 8457.30.00.10, general (MFN) 3.3%; if not, use 8457.30.00.90, general (MFN) 3.3%.
