As printed in the order notice (82 FR 18422, April 19, 2017). Your deposit today may differ: it is the rate the latest administrative review assigned to the exporter or producer on your invoice, which can be higher or lower. A company that has never been reviewed keeps the all-others rate. Check your supplier's current rate in Commerce's ACCESS case record before you price an order.

What A-570-044 means when you import
Cash deposit at entry. For every entry of goods in scope, CBP collects an estimated antidumping duty cash deposit at the rate assigned to the exporter or producer on the entry, on top of the Column 1 duty and any Chapter 99 trade-remedy lines.
Your supplier sets your rate. The same product from two plants in China can deposit at different rates. Before you price the order, ask the supplier which legal entity will appear as exporter and as producer on the invoice. China is treated as a non-market economy in antidumping cases: an exporter that has not established its own separate rate deposits at the country-wide rate, which is normally the highest in the case.
Deposit now, final duty later. The deposit is not the final duty. The entry stays unliquidated until Commerce completes the administrative review for the period it was entered in. CBP then liquidates it at the rate that review sets and bills or refunds the difference with interest. AD/CVD entries can stay open for years, and the importer of record carries the difference. A review happens only if Commerce is asked for one in the order's anniversary month; if nobody asks, entries liquidate at the deposit rate.
Reimbursement certificate. Before liquidation, the importer files a certificate under 19 CFR 351.402(f)(2) stating whether the exporter has paid or reimbursed the antidumping duty. Without it, Commerce may presume reimbursement and deduct the duty a second time in the margin calculation. Brokers file it with the entry summary; make sure yours does.
Entry reporting. The AD/CVD case number goes on the 7501 line alongside the HTS number, and any Chapter 99 lines the goods carry are reported in the order CBP prescribes; the tariff updates tracker carries the current Chapter 99 sequence and the actions behind it.
Shipping from a third country doesn't change the origin. Goods finished, cut or packaged in a third country stay in scope if the notice's written scope covers them. A change of shipping origin is not a change of AD/CVD origin.
Estimating the stack. The tariff simulator returns the Column 1 rate and the Chapter 99 additional duties for an HTS number and origin. It does not include antidumping or countervailing deposits, so add the deposit at your supplier's current rate on top.
