Rates in the order notice
19.61%All-others weighted-average dumping margin
As printed in the order notice (82 FR 42790, 12 September 2017). 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 of the orders includes,
but is not limited to, ESB rubber in primary forms, bales, granules,
crumbs, pellets, powders, plates, sheets, strip, etc. ESB rubber
consists of non-pigmented rubbers and oil-extended non-pigmented
rubbers, both of which contain at least one percent of organic acids
from the emulsion polymerization process.
ESB rubber is produced and sold in accordance with a generally
accepted set of product specifications issued by the International
Institute of Synthetic Rubber Producers (IISRP). The scope of the
investigations covers grades of ESB rubber included in the IISRP
1500 and 1700 series of synthetic rubbers. The 1500 grades are light
in color and are often described as ``Clear'' or ``White Rubber.''
The 1700 grades are oil-extended and thus darker in color, and are
often called ``Brown Rubber.''
Specifically excluded from the scope of these orders are
products which are manufactured by blending ESB rubber with other
polymers, high styrene resin master batch, carbon black master batch
(i.e., IISRP 1600 series and 1800 series) and latex (an intermediate
product).
The products subject to these orders are currently classifiable
under subheadings 4002.19.0015 and 4002.19.0019 of the Harmonized
Tariff Schedule of the United States (HTSUS). ESB rubber is
described by Chemical Abstract Services (CAS) Registry No. 9003-55-
8. This CAS number also refers to other types of styrene butadiene
rubber. …

What A-351-849 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 Brazil 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. Airlift USA does not hold a US customs broker licence; entries on cargo we move are filed through our licensed broker network.
