What is the deposit rate for A-570-962?

How do I check if my shipment falls within the scope of A-570-962?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (2 flagged); and (2) the product's country of origin — this order applies to imports from China. 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. Tandom's lookup tool matches your HTS + origin against every active order in seconds.

What HTS codes are covered by A-570-962?

A-570-962 flags 2 HTS codes in Tandom's catalog. The full list is shown on this page. HTS coverage alone does not guarantee scope — physical-characteristic exclusions in the scope text may carve out specific products.
