Frequently asked questions

What is AD/CVD case A-570-882?

The country-wide cash deposit rate for A-570-882 is 135.18%. This rate applies to importers of non-listed manufacturers/exporters from China.

How do I check if my shipment falls within the scope of A-570-882?

The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce.
