Rates published in the order notice

65.85%All-others subsidy rate

As printed in the order notice (80 FR 5082, January 30, 2015). 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.

HTS numbers named in the scope

The notice lists these subheadings for convenience only. The written scope decides whether goods are covered, and goods entered under other HTS numbers can still be in scope.

What C-570-009 means when you import

Cash deposit at entry. For every entry of goods in scope, CBP collects an estimated countervailing 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. Because a companion antidumping case exists, an entry of Calcium Hypochlorite from China carries both deposits.

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.

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.
