U.S. Department of Commerce issues antidumping duty order on polypropylene corrugated boxes from Vietnam

Importers of Vietnamese polypropylene corrugated boxes face AD duties on entries from 31 December 2025 and cash deposits once the ITC injury determination publishes

Change
Commerce issued an antidumping duty order on polypropylene corrugated boxes from Vietnam (HTSUS 3923.10.9000), directing CBP to assess AD duties on unliquidated entries entered or withdrawn for consumption on or after 31 December 2025. Cash deposits at the estimated weighted-average dumping margins, and reinstituted suspension of liquidation, take effect on the date the ITC's final affirmative injury determination is published in the Federal Register; entries from 29 June 2026 until that publication are liquidated without AD duties.
Why it matters
The order follows affirmative final determinations by Commerce (20 May 2026) and the ITC (6 July 2026). Unliquidated entries entered or withdrawn for consumption on or after 31 December 2025 are subject to AD duties, while entries entered on or after 2 October 2025 but before 31 December 2025 have suspension lifted and prior cash deposits refunded, the ITC having found no critical circumstances. Because provisional measures lapsed on 29 June 2026, entries from that date through the day before the ITC final-determination publication are liquidated without AD duties; suspension of liquidation and cash-deposit collection at the estimated dumping margins resume from that publication date. The written scope description governs over the HTSUS number.
Implications
  • Importers of polypropylene corrugated boxes from Vietnam must account for AD duties on unliquidated entries entered or withdrawn for consumption on or after 31 December 2025, and must fund cash deposits at the estimated weighted-average dumping margins once the ITC's final injury determination is published, because CBP will assess duties and collect deposits on subject entries from that date.
  • Customs brokers and import-entry filers must update entry classifications and payment instructions to apply cash deposits from the ITC-determination publication date and to process refunds for entries entered or withdrawn between 2 October 2025 and 31 December 2025 when Commerce instructs CBP to lift suspension, because mistiming duties or deposits against the liquidation gap (29 June 2026 to that publication) will misapply charges.
Who is affected
  • Importers of polypropylene corrugated boxes from Vietnam
  • Customs brokers and import-entry filers handling polypropylene corrugated box imports
What to watch
  • Publication of the ITC's final affirmative injury determination in the Federal Register triggers reinstituted suspension of liquidation and cash-deposit collection at the estimated weighted-average dumping margins.
  • Entry of appearance in Commerce's ACCESS system due within 30 days of publication to join the order's annual inquiry service list.
