ITC votes that ending the US duty on Chinese diamond sawblades would hurt US makers

The US anti-dumping duty on diamond sawblades from China has cleared a key step towards staying in place. The US International Trade Commission voted that ending it would likely hurt US makers.

The ITC decided in an expedited five-year check, a sunset review. Its notice appeared in the Federal Register on 30 October 2026. It found "that revocation of the antidumping duty order on diamond sawblades and parts thereof from China would be likely to lead to continuation or recurrence of material injury to an industry in the United States within a reasonably foreseeable time."

The order covers diamond sawblades and their parts. The notice gives no rates.

This matters for US importers of these blades and parts, such as tool and building suppliers. It also matters for Chinese makers.

The duty is not formally renewed yet. That needs a separate notice from the Department of Commerce. The ITC notice does not say when that will come.

What to check

• Do you import diamond sawblades or parts from China?
• What deposit rate do you pay today?
• Will you watch for the Commerce notice?
