C-570-191: countervailing duty order on Sol Gel Alumina-Based Ceramic Abrasive Grains from China
C-570-191 is the US Department of Commerce case number for the countervailing duty order on Sol Gel Alumina-Based Ceramic Abrasive Grains from China, in force since 29 September 2025. Goods in scope entered under this case carry a countervailing cash deposit at entry on top of the normal duty.
Reviewed September 2026 against the ITA order list and the Federal Register.

Rates in the order notice
165.05%All-others subsidy rate
As printed in the order notice (90 FR 46555, 29 September 2025). 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.

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
The merchandise covered by these orders is sol gel alumina-based
ceramic abrasive grains which are comprised of minimum 94% aluminum
oxide (Al2O3), and may contain other compounds, including, but not
limited to, titanium dioxide, silicon dioxide, calcium oxide, sodium
superoxide, ferric oxide, magnesium oxide, di-aluminum magnesium
tetroxide, lanthanum oxide, lanthanum magnesium oxide, zirconium
dioxide, or zirconium carbonate. Grain sizes of sol gel alumina-
based ceramic abrasive grains range from 0.85 mm to 0.0395 mm (which
corresponds to American National Standards Institute (ANSI) grit
sizes from 20 to 280).
Shapes include but are not limited to angular, sharp, extra
sharp, blocky, splintery, round stripped, triangular or shaped like
extruded rods or stars.
Ceramic abrasive grains have unique crystalline structures that
impart certain advanced properties, such as their extreme hardness
and strength ranging between 16 and 22 gigapascals by the Vickers
Diamond Indent Method, high melting point (2050 [deg]C), and a
single- or multi-phase microstructure, which may contain multiple
phases, having crystalline sizes ranging from 0.05 to 30[micro]m. …

What C-570-191 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 Sol Gel Alumina-Based Ceramic Abrasive Grains 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. Airlift USA does not hold a US customs broker licence; entries on cargo we move are filed through our licensed broker network.
