Rates in the order notice

5.41%All-others weighted-average dumping margin

As printed in the order notice (85 FR 52546, 26 August 2020). The deposit an entry pays today is the rate assigned to the exporter or producer on the invoice in the latest administrative review, which can be higher or lower than this; a company that has never been reviewed keeps the all-others rate. Check the current rate for your supplier in Commerce's ACCESS case record before pricing an order.

Scope, from the order notice

Scope of the Order on Vietnam The merchandise covered by this order consists of certain wind towers, whether or not tapered, and sections thereof. Certain wind towers support the nacelle and rotor blades in a wind turbine with a minimum rated electrical power generation capacity in excess of 100 kilowatts and with a minimum height of 50 meters measured from the base of the tower to the bottom of the nacelle (i.e., where the top of the tower and nacelle are joined) when fully assembled. A wind tower section consists of, at a minimum, multiple steel plates rolled into cylindrical or conical shapes and welded together (or otherwise attached) to form a steel shell, regardless of coating, end-finish, painting, treatment, or method of manufacture, and with or without flanges, doors, or internal or external components (e.g., flooring/decking, ladders, lifts, electrical buss boxes, electrical cabling, conduit, cable harness for nacelle generator, interior lighting, tool and storage lockers) attached to the wind tower section. …

What A-580-902 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. The same product from two plants in South Korea can deposit at different rates, so ask the supplier which legal entity will appear as exporter and as producer on the invoice before you price the order.

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, then CBP liquidates it at the rate that review sets, and bills or refunds the difference with interest. AD/CVD entries therefore stay open for years, and the importer of record carries the difference. Commerce must be asked for a review each anniversary month of the order; 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. If it is not filed, 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. Goods finished, cut or packaged in a third country stay in scope if the notice's written scope covers them, so 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 add antidumping or countervailing deposits. Add the deposit at your supplier's current rate on top of what it shows.
