Commerce Finds Compacted Graphite Iron Brake Drums From China Circumvent the Orders — Duties Reach Back to January 27, 2026

A preliminary affirmative determination under section 781(d) pulls a later-developed product into existing AD/CVD orders, with cash deposits at 150.25 percent AD and 11.94 percent CVD.

On September 22, 2026 the U.S. Department of Commerce published a preliminary affirmative determination of circumvention in A-570-174 and C-570-175, finding that compacted graphite iron brake drums from the People's Republic of China are later-developed merchandise circumventing the antidumping and countervailing duty orders on certain brake drums from China.

On September 22, 2026 the U.S. Department of Commerce published a preliminary affirmative determination of circumvention covering certain brake drums from the People's Republic of China, under case numbers A-570-174 and C-570-175. Commerce preliminarily determines that compacted graphite iron brake drums from China constitute later-developed merchandise that is circumventing the existing antidumping and countervailing duty orders, and that the merchandise should therefore be brought inside the scope of those orders.

The determination is applicable September 22, 2026 and is country-wide in scope. For importers of heavy-duty truck and trailer components through Long Beach, Los Angeles and Oakland, the operative detail is not the finding itself but the date to which it reaches back.

What "later-developed merchandise" means

Most circumvention inquiries that importers encounter involve minor alterations to a product, or assembly of parts in a third country. Section 781(d) of the Tariff Act of 1930, as amended, addresses a different situation: merchandise developed after an order was issued, which the order's scope language did not and could not describe because the product did not yet exist in that form.

That is the theory here. The orders on brake drums from China cover drums made of gray cast iron, whether finished or unfinished, with an actual or nominal inside diameter of 14.75 inches or more but not over 16.6 inches, weighing more than 50 pounds. Compacted graphite iron is a different material. The inquiry asked whether a CGI drum in the same dimensional range is nonetheless the later-developed form of the covered product, and Commerce has preliminarily answered yes.

This matters as a general lesson well beyond brake drums. An importer who reads a scope description, notes that its product is made of a material the description does not name, and concludes it is outside the order has done only half of the analysis. Section 781(d) exists precisely to reach that reasoning.

How the inquiry got here

Commerce published the AD and CVD orders on brake drums from China and Türkiye on August 12, 2025, at 90 FR 38730 and 90 FR 38753 respectively. On January 27, 2026, in response to a request from Webb Wheel Products, Inc., a domestic interested party, Commerce initiated a country-wide circumvention inquiry under section 781(d) and 19 CFR 351.226, published at 91 FR 3435.

On April 20, 2026 Commerce selected three mandatory respondents, listed alphabetically: CAIEC Trailer Master Co., Ltd.; Kara CVS Inc.; and Trailer MASTER CVS INC. Commerce then extended the preliminary determination deadline twice — by 60 days on May 13, 2026, and by a further 23 days on July 30, 2026 — moving the deadline to September 17, 2026.

The inquiry merchandise is described as CGI brake drums with an actual or nominal inside diameter of 14.75 inches or more but not over 16.6 inches, weighing more than 50 pounds, produced in China and exported to the United States. The notice gives model number M328D557 produced by PanAsia CVS (HK) Limited as an example.

The retroactivity is the headline

Under 19 CFR 351.226(l)(2), Commerce will direct U.S. Customs and Border Protection to suspend liquidation on unliquidated entries of CGI brake drums from China entered, or withdrawn from warehouse, for consumption on or after January 27, 2026 — the publication date of the initiation notice.

Read that date against the calendar. An importer who brought in a container of CGI brake drums in February, March or June of 2026, cleared entry without incident and moved the goods into inventory, is now looking at entries that will be suspended and assessed. The merchandise may already be installed on trailers in service. The duty exposure attaches regardless.

This is the single most misunderstood feature of circumvention practice. Importers frequently assume that a determination operates prospectively — that the rule changes on the day Commerce announces it. It does not. The initiation notice is the marker, and it published eight months ago.

The cash deposit rates

Commerce intends to instruct CBP to collect cash deposits for estimated antidumping and countervailing duties at the rates applicable under the existing orders. For the antidumping side, that is the China-wide entity rate of 150.25 percent. For the countervailing side, it is the all-others rate of 11.94 percent. Companies that have their own company-specific rate under the orders will be assigned that rate instead.

Combined, an importer without a company-specific rate faces cash deposits exceeding 162 percent of entered value. On a product whose landed cost was the reason for sourcing it from China in the first place, that is not a margin adjustment — it is a different business. The suspension of liquidation and cash deposit requirements remain in effect until further notice.

What the deadlines are, and how short they are

Under 19 CFR 351.226(f)(4), case briefs or other written comments are due no later than 14 days after publication of the notice — that is, by October 6, 2026. Rebuttal briefs, limited to issues raised in case briefs, are due no later than seven days after the case brief deadline, or October 13, 2026.

Commerce asks that parties submit with each argument a statement of the issue, a brief summary of the argument, and a table of authorities, and that each issue carry a public executive summary of no more than 450 words excluding citations. Commerce uses those summaries as the basis for the comment summaries in the issues and decision memorandum accompanying the final determination.

Parties wishing to request a hearing must do so in writing within 30 days of publication, filed electronically through ACCESS. All submissions must be received in their entirety by ACCESS by 5:00 p.m. Eastern Time on the applicable deadline.

Fourteen days is not a long time to assemble a substantive brief on a technical metallurgical question. Importers who believe their product is genuinely distinct — different dimensions, different weight, a different application — need to be moving now rather than after the final determination.

The ITC's role from here

Consistent with section 781(e) of the Act, Commerce will notify the U.S. International Trade Commission of the preliminary determination to include the inquiry merchandise within the orders. The ITC may request consultations concerning the proposed inclusion. If, after consultations, the Commission believes a significant injury issue is presented, it has 60 days from the date of Commerce's notification to provide written advice.

That is a real procedural avenue, though a narrow one. It addresses injury, not the metallurgical question of whether CGI drums are later-developed merchandise.

What importers of Chinese-origin components should take from this

First, if you import brake drums from China in the covered dimensional range, determine the material composition of every part number you have entered since January 2026. "Cast iron" on a commercial invoice is not an answer; compacted graphite iron is a specific material with a specific microstructure, and your supplier knows which one it supplied.

Second, reconcile that answer against your entries. Identify which entries remain unliquidated, because those are the ones suspension reaches.

Third, treat this determination as a template rather than an isolated event. Circumvention inquiries under section 781(d) are the mechanism by which orders follow product development, and the same logic applies to any covered product where a material substitution has been marketed as taking goods outside an order. A defensible tariff classification and scope position is one that was analyzed and documented before entry, not reconstructed after a determination publishes.

Fourth, be careful about the neighboring theory. Where the response to an order has been to shift assembly or finishing to a third country rather than to change the material, the exposure runs through country of origin and substantial transformation analysis instead, and a supplier's assurance about origin is not a substitute for that analysis.

Fifth, if entries are already suspended, the immediate questions are financial rather than legal: bond sufficiency, cash deposit funding, and whether your customs bond will need to be increased to cover the new exposure. Importers moving volume through the Long Beach and Los Angeles complex should raise that with their surety before CBP raises it with them.

Where this leaves the record

This is a preliminary determination. Commerce may change its analysis in the final determination, and the briefing schedule exists so that interested parties can try to persuade it to. But suspension of liquidation and the cash deposit requirement are in effect now, and they remain in effect until further notice. Importers should plan around the determination as it stands while preserving whatever arguments the record supports.

Frequently Asked Questions

How far back do these duties reach?

Under 19 CFR 351.226(l)(2), Commerce will direct CBP to suspend liquidation of unliquidated entries entered, or withdrawn from warehouse for consumption, on or after January 27, 2026 — the publication date of the initiation notice, eight months before the determination. An importer who brought in CGI brake drums in February, March or June 2026 and cleared entry without incident is looking at entries that will be suspended and assessed, even if the drums are already installed on trailers in service.

What are the cash deposit rates?

Commerce intends to instruct CBP to collect at the rates applicable under the existing orders: the China-wide entity rate of 150.25 percent on the antidumping side and the all-others rate of 11.94 percent on the countervailing side. Combined, an importer without a company-specific rate faces cash deposits exceeding 162 percent of entered value. Companies with their own company-specific rate under the orders are assigned that rate instead.

My drums are compacted graphite iron, and the orders say gray cast iron. Doesn't that put me outside?

That is exactly the reasoning section 781(d) exists to reach. The provision addresses merchandise developed after an order issued, which the scope language could not describe because the product did not yet exist in that form. Commerce has preliminarily determined that a CGI drum in the same dimensional range is the later-developed form of the covered product. Reading a scope description, noting your material is not named, and concluding you are outside the order is only half the analysis.

Which products are actually covered?

CGI brake drums with an actual or nominal inside diameter of 14.75 inches or more but not over 16.6 inches, weighing more than 50 pounds, produced in China and exported to the United States. The notice gives model number M328D557 produced by PanAsia CVS (HK) Limited as an example. The determination is country-wide, so it is not limited to the three mandatory respondents.

What are the deadlines to comment?

Short. Under 19 CFR 351.226(f)(4), case briefs or other written comments are due no later than 14 days after publication — by October 6, 2026. Rebuttal briefs, limited to issues raised in case briefs, are due seven days after that.
