Scope, from the order notice

Scope of the Order The scope of this order includes certain chemically-bonded (resin or pitch), magnesia carbon bricks with a magnesia component of at least 70 percent magnesia (``MgO'') by weight, regardless of the source of raw materials for the MgO, with carbon levels ranging from trace amounts to 30 percent by weight, regardless of enhancements (for example, magnesia carbon bricks can be enhanced with coating, grinding, tar impregnation or coking, high temperature heat treatments, anti-slip treatments or metal casing) and regardless of whether or not antioxidants are present (for example, antioxidants can be added to the mix from trace amounts to 15 percent by weight as various metals, metal alloys, and metal carbides). Certain magnesia carbon bricks that are the subject of this order are currently classifiable under subheadings 6902.10.1000, 6902.10.5000, 6815.91.0000, 6815.99.2000 and 6815.99.4000 of the Harmonized Tariff Schedule of the United States (``HTSUS''). While HTSUS subheadings are provided for convenience and customs purposes, the written description is dispositive.

What C-570-955 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 Magnesia Carbon Bricks from China carries both deposits. The same product from two plants in China 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.
