Canada’s investigations into the alleged dumping and subsidizing of certain paperboard cups and containers imported from China have reached an important milestone.
On October 16, 2026, the Canadian International Trade Tribunal (CITT) determined that there is a reasonable indication that the dumping and subsidizing of the subject goods from China have caused injury to the Canadian domestic industry.
This preliminary injury determination allows the investigations to proceed. However, it does not constitute a final finding of dumping or subsidizing, nor does it mean that new anti-dumping or countervailing duties have already taken effect.
Background of the Investigations
The investigations were initiated following a complaint filed by Great Pacific Enterprises Limited Partnership, operating as Genpak, a Canadian manufacturer of paperboard packaging products.
On August 17, 2026, the Canada Border Services Agency (CBSA) formally initiated dumping and subsidy investigations under the Special Import Measures Act (SIMA).
The investigations cover certain paperboard cups and containers manufactured from coated paperboard stock, as well as certain pre-cut blanks or flats used to manufacture these products.
The subject goods are usually classified under the following Canadian tariff classification numbers:
- 4823.69.00.10
- 4823.69.00.90
Importers should note that not every product classified under these tariff numbers is necessarily subject to the investigations. The scope is determined by the CBSA’s official product definition, including applicable material specifications and exclusions.
What Happens Next?
According to the CBSA’s published investigation schedule, preliminary determinations are expected by November 16, 2026.
If the CBSA makes affirmative preliminary determinations of dumping or subsidizing, provisional anti-dumping and/or countervailing duties may become applicable to subject goods imported into Canada from that point forward.
The CBSA and CITT would then continue their respective investigations toward final determinations and findings.
What Canadian Importers Should Know
Businesses importing disposable paper cups, takeout containers and related paperboard packaging from China should carefully review their potential exposure.
Key considerations include:
- Confirm product coverage. Similar product descriptions do not necessarily mean that goods fall within the legal scope of the investigations.
- Review potential landed costs. Future provisional or final SIMA duties could significantly affect import costs.
- Maintain accurate supplier and product records. Detailed specifications, manufacturer information, commercial invoices and origin documentation can support compliance reviews.
- Monitor upcoming CBSA decisions. The November 16 preliminary determinations will be an important development for affected importers.
