Rates in the order notice

257.11%China-wide Entity rate

As printed in the order notice (83 FR 37468, 1 August 2018). 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.

HTS numbers named in the scope

The subheadings the notice lists as the ones subject merchandise may enter under. They are given for convenience; the written scope is what decides whether goods are covered, and goods under other numbers can still be in scope.

Scope, from the order notice

scope of the investigation if performed in the country of manufacture of the stainless steel flanges. Merchandise subject to the order is typically imported under headings 7307.21.1000 and 7307.21.5000 of the Harmonized Tariff Schedule of the United States (HTSUS). While HTSUS subheadings and ASTM specifications are provided for convenience and customs purposes, the written description of the scope is dispositive.

Excerpt from 83 FR 37468. Scopes are amended by later scope rulings and circumvention findings; the notice list below has them.

What A-570-064 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. Because a companion countervailing case exists, an entry of Stainless Steel Flanges 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. 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, 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.
