Malaysia Won’t Save You

If you are still relying on simple third-country finishing to clear Chinese inputs of Antidumping and Countervailing Duty (AD/CVD) exposure, the U.S. Department of Commerce just issued a sharp reality check.

In a newly published preliminary affirmative circumvention determination (91 FR 42713, effective July 10), Commerce ruled that paper plates finished in Malaysia using Chinese-origin paperboard are evading existing AD/CVD orders. Commerce reached a parallel affirmative finding for paper plates finished in Cambodia in a companion notice published the same day.

This isn’t just about paper plates. It is a clean, textbook case study in the growing regulatory intolerance for “substantial transformation” arguments that rely on minor processing in a third country. The inquiry was brought under section 781(b) of the Tariff Act of 1930 — the classic anti-circumvention tool — after a request from the American Paper Plate Coalition’s Anticircumvention Working Group.

Here is why it matters, and why compliance teams need to move now.

// 1. The retroactive certification trap

The real sting in this determination is its lookback period. Commerce isn’t just looking forward. It has directed CBP to suspend liquidation on unliquidated entries of paper plates from Malaysia entered on or after August 22, 2025 — the date the inquiry was initiated.

Importers and exporters must complete and sign strict country-of-origin certifications, and upload them (along with commercial invoices and paperboard-origin documentation) to the Document Image System in ACE, by August 7, 2026.

Importers who assumed their Malaysian supply chains were safe now face sudden, retroactive duty exposure and an aggressive, less-than-a-month deadline to produce airtight recordkeeping. Where the certification and supporting documentation cannot be produced, entries are exposed to AD/CVD cash-deposit requirements:

// 2. The death of the “minor processing” loophole

For years, converting raw or semi-finished Chinese inputs into a final product in Southeast Asia was a go-to strategy to alter country-of-origin designations. Commerce is increasingly pulling back the curtain on these operations.

If the core value and material — in this case, the paperboard — originate in China, minor conversion steps like cutting, pressing, or packaging in Malaysia will no longer shield you from AD/CVD enforcement. The section 781(b) analysis weighs factors such as the level of investment and R&D in the third country, the nature of the production process, and the value added there against the value of the Chinese input.

When the third-country step is thin, the finding writes itself.

// 3. A blueprint for broader scrutiny

Expect this exact playbook to be replicated across other industries. Whether you are importing electronics, textiles, or battery components, if your supply chain relies on a “China + 1” strategy where the primary inputs are Chinese, your duty exposure is rising.

The paper-plate matter is notable precisely because it is unglamorous — a commodity product with a simple bill of materials — which makes it an easy template for Commerce to apply to more complex goods.

// What your team should do before August 7

• Map the raw-material DNA. Trace every Chinese-origin input in products finished in Malaysia or Cambodia — paperboard here, but wafers, yarn, or cells elsewhere — not just the country where final assembly occurs.
• Pull your unliquidated entries. Identify all in-scope entries dated on or after August 22, 2025 and flag those still unliquidated and therefore exposed.
• Secure certifications now. Obtain signed importer and exporter certifications, commercial invoices, and paperboard-origin documentation, and upload them to DIS in ACE before the August 7 deadline.
• Stress-test your other “China + 1” lanes. Apply the same origin-tracing to electronics, textiles, and battery-component sourcing to find exposure before a petitioner does.
• Budget for cash-deposit exposure. Model the full duty impact on any lane where third-country processing is minor relative to the Chinese input — 515.40% AD plus 10.61% CVD is not a rounding error.

// The takeaway

Compliance is no longer about where the final box is taped shut. It’s about mapping the raw-material DNA of your product.

This is a preliminary determination, and parties will have the opportunity to comment before Commerce issues its final result — but the suspension of liquidation and the certification obligations are live now. If you have unliquidated entries in this space, your clock is ticking toward August 7.

How is your team auditing third-country finishing operations this year to get ahead of retroactive determinations?
