Commerce opens circumvention inquiry into Chinese magnesia carbon bricks

Commerce opens circumvention inquiry into Chinese magnesia carbon bricks

Rule Changes

After an appeals court said alumina-bearing bricks fall outside the duty orders, Commerce is testing a different legal route to reach them

Today: Commerce opens country-wide circumvention inquiry

Overview

Updated 59 minutes ago

On November 10, the Commerce Department opened a country-wide inquiry into whether Chinese refractory bricks containing a small amount of alumina are dodging antidumping and countervailing duties on magnesia carbon bricks. The question is narrow: does adding more than zero but less than five percent alumina by weight change the product enough to escape the order?

A federal appeals court said in August that it does, and that Commerce cannot close the gap by reinterpreting the order's scope. The circumvention inquiry is a separate legal door. If it succeeds, duties would reach bricks the courts have said are outside the orders — and could apply to entries made before the inquiry began.

Why it matters

If Commerce finds circumvention, importers of alumina-bearing bricks face duty deposits on suspended entries, with retroactive exposure back to November 2021.

  1. Commerce opens country-wide circumvention inquiry

    Today Investigation

    The inquiry covers Chinese bricks with more than zero but less than five percent alumina, and Commerce directs continued suspension of liquidation.

    Procedure

    The agency adds 15 days to the deadline for deciding whether to open the inquiry.

  3. FRC Global challenges the request's adequacy

    Filing

    The company files comments questioning whether the request meets Commerce's regulatory requirements.

  4. Domestic producers file circumvention request

    Filing

    The Committee asks Commerce to treat trace-alumina bricks as a minor alteration under section 781(c).

  5. Appeals court rejects Commerce's alumina threshold

    Legal

    The Federal Circuit affirms that Commerce unlawfully expanded the orders by setting a five percent alumina floor.

  6. Federal Circuit rules alumina takes bricks out of scope

    Legal

    Fedmet I holds that adding alumina to a magnesia carbon brick removes it from the duty orders.

Scenarios

1

Commerce finds circumvention, duties reach trace-alumina bricks

Possible Resolves by Sep 6, 2027

Discussed by: Trade counsel following the Federal Register notice; MLex and Law360 coverage of the inquiry

Commerce concludes that adding a small amount of alumina is a minor alteration that does not change the brick's physical characteristics, end use, or marketing channels enough to escape the orders. An affirmative final determination extends the deposit requirement to trace-alumina bricks and lets Customs pursue unliquidated entries going back as far as November 4, 2021.

2

Commerce finds no circumvention, alumina bricks stay outside

Possible Resolves by Sep 6, 2027

Discussed by: Importers and counsel who argued the alumina addition is a real product change

Commerce concludes that the alumina addition changes the brick's performance enough that it is not a minor alteration, or that the statutory criteria are not met. The orders stay as the Federal Circuit read them, and trace-alumina bricks remain outside scope. The Committee's remaining route would be another appeal.

3

Preliminary finding goes affirmative, deposits expand

Uncertain Resolves by Apr 9, 2027

Discussed by: Trade practitioners watching the 150-day clock

Commerce issues an affirmative preliminary determination by April 2027, which under its regulations triggers suspension of liquidation and cash deposit requirements for unliquidated entries on or after November 10, 2026. Importers would begin posting deposits months before the final ruling, and a later negative final would require refunds.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2014

Fedmet I (2014)

The Federal Circuit reviewed whether magnesia carbon bricks with added alumina fell within the antidumping and countervailing duty orders. The court held that adding alumina took the brick outside the scope of the orders as written.

Then

Importers of alumina-bearing bricks were treated as outside the orders.

Now

The decision set the baseline that Commerce could not later override by reinterpreting the scope language.

Why this matters now

The 2026 circumvention inquiry exists because the Committee could not get around Fedmet I through a scope ruling.

2021-2026

The scope ruling fight and remand (2021-2026)

Commerce initially determined that bricks with five percent or less alumina remained within the orders. The Court of International Trade sent the matter back, and Commerce on remand concluded under protest that the bricks were outside scope. The trade court sustained that redetermination, and the Committee appealed.

Then

Alumina-bearing bricks stayed outside the orders while the appeal ran.

Now

The Federal Circuit's August 2026 affirmance closed the scope-ruling path and pushed the dispute into the circumvention statute.

Why this matters now

The failed scope route is why Commerce is now testing section 781(c) instead of reinterpreting the order.

November 2021

Circumvention retroactivity rule takes effect (2021)

Commerce's revised circumvention regulations took effect on November 4, 2021, setting out procedures for inquiries and the reach of suspension of liquidation.

Then

Commerce gained a defined process for opening circumvention inquiries and directing Customs action.

Now

The rules set November 4, 2021 as the outer limit for retroactive suspension in cases like this one.

Why this matters now

The November 2026 notice cites that date as the earliest point to which any retroactive deposit demand could reach.
