Which countries are covered by the US AD/CVD orders on PP corrugated boxes?

China (antidumping and countervailing duty orders published March 16, 2026) and Vietnam (antidumping order, July 2026). Boxes made in other countries are not covered by these orders, but they still pay normal duty and any other tariffs, such as Section 301.

Who makes corrugated plastic produce boxes in the United States?

The four petitioners in the 2025 case are US makers: Inteplast Group, SeaCa Plastic Packaging, CoolSeal USA and Technology Container Corp. Plastpac also supplies corrugated plastic cartons for iced vegetables and seafood.

Do PP boxes from the Philippines pay US import duty?

Yes. They carry 0% U.S. antidumping and countervailing duty because the orders name only China and Vietnam, but a 12.5% Section 301 tariff (since July 24, 2026) and the normal HTSUS duty (3% under 3923.10.90) apply. Confirm the current rates with your customs broker.

How do I avoid a circumvention problem when buying from a third country?

Ask where the PP sheet is extruded, keep the sheet supplier invoice and production records, and make sure the producer and exporter on your documents match the plant that actually makes the boxes.

Corrugated Plastic (PP) Box Suppliers Outside China and Vietnam: 2026 Options for US Importers

Quick answer: Since the US antidumping and countervailing duty orders on polypropylene corrugated boxes from China (March 16, 2026) and Vietnam (July 2026), importers who need PP corrugated produce or seafood boxes have three kinds of sources: US makers (Inteplast Group, SeaCa Plastic Packaging, CoolSeal USA, Technology Container Corp, Plastpac), other non-subject countries (for example Corex in Australia, Cipasi in Spain and Ondaplast in Italy), and Philippine production such as Fuxing Group's plant in Calamba, Laguna. Boxes made in the Philippines carry 0% U.S. AD/CVD — not 0% import duty: a 12.5% Section 301 tariff (since July 24, 2026) plus the normal HTSUS duty apply; confirm with your broker. Whichever supplier you use, ask where the PP sheet is extruded and keep that evidence with your entry.

Why buyers are looking outside China and Vietnam

The US Department of Commerce published antidumping and countervailing duty orders on polypropylene corrugated boxes from China on March 16, 2026 (Federal Register doc. 2026-05003): the China-wide antidumping cash deposit is 82.21% after subsidy offset and the countervailing rate is 62.27%. An antidumping order on Vietnam followed in July 2026, with a Vietnam-wide rate of 130.58%. The scope covers boxes, bins, totes and similar containers made from corrugated PP sheet, generally entered under HTS 3923.10.9000; the written scope, not the tariff number, decides coverage. The petitioners were four US makers: CoolSeal USA, Inteplast Group, SeaCa Plastic Packaging and Technology Container Corp.

Five questions to ask any non-subject supplier

Question	Why it matters
Where is the PP sheet extruded, and where is the box die-cut and assembled?	Boxes converted in a third country from Chinese or Vietnamese sheet can attract circumvention inquiries. Ask for the sheet invoice and production records.
Who is the producer and who is the exporter on the commercial invoice?	Your broker needs a consistent producer/exporter pair and country of origin.
Which HTS number and which duties will apply at entry?	Section 301 and normal HTSUS duty still apply to non-subject origins.
What thickness and gsm, and what static load per box?	Iced broccoli and seafood need 4–5 mm board; see the thickness guide.
Can I get physical samples and a pilot load before the season?	Lead time from Asia is 5–7 weeks door to door; plan the first order 8–10 weeks ahead.
