Rates in the order notice

201.59%All-others weighted-average dumping margin

As printed in the order notice (84 FR 55912, 18 October 2019). 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 Order The merchandise covered by this order is glycine at any purity level or grade. This includes glycine of all purity levels, which covers all forms of crude or technical glycine including, but not limited to, sodium glycinate, glycine slurry and any other forms of amino acetic acid or glycine. Subject merchandise also includes glycine and precursors of dried crystalline glycine that are processed in a third country, including, but not limited to, refining or any other processing that would not otherwise remove the merchandise from the scope of this order if performed in the country of manufacture of the in-scope glycine or precursors of dried crystalline glycine. Glycine has the Chemical Abstracts Service (CAS) registry number of 56-40-6. Glycine and glycine slurry are classified under Harmonized Tariff Schedule of the United States (HTSUS) subheading 2922.49.43.00. Sodium glycinate is classified in the HTSUS under 2922.49.80.00. While the HTSUS subheadings and CAS registry number are provided for convenience and customs purposes, the written description of the scope of this order is dispositive.

What A-549-837 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 Thailand 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.
