Canada has opened new trade investigations into certain paperboard products from China.
On August 17, 2026, the Canada Border Services Agency (CBSA) initiated dumping and subsidy investigations concerning certain paperboard cups and containers originating in or exported from China.
The investigations followed a complaint from Canadian producer Great Pacific Enterprises Limited Partnership (Genpak). Genpak alleges that increasing volumes of dumped and subsidized imports have caused material injury to domestic production.
For packaging buyers, importers and international brands, the case is a reminder that the cost of imported packaging is not determined by the factory quotation alone.
Tariffs, trade remedies, product classification and country of origin can all influence the final landed cost of packaging.
What products are actually under investigation?
The scope of the investigation matters. The case does not cover all paper packaging imported from China.
According to the CBSA’s product definition, the investigation concerns certain paperboard cups and containers rolled from coated paperboard stock, as well as blanks or flats used to form those products.
These products are generally disposable paperboard items used to serve food and hot or cold beverages.
The goods are usually imported under these tariff classification numbers:
- 4823.69.00.10;
- 4823.69.00.90.
Tariff codes alone do not determine whether a product falls within a trade investigation. Product descriptions, materials and construction also need to be considered.
For buyers sourcing folding cartons, rigid boxes, gift boxes, mailer boxes or other paper packaging, this distinction matters. The current investigation should not be interpreted as a general Canadian trade action against all Chinese paper packaging.
Why did Canada launch the investigation?
The investigation followed a complaint filed by Canadian producer Genpak.
The complainant alleges that Chinese imports are being sold in Canada at unfairly low prices or are benefiting from subsidies.
According to the complaint information referenced by Canadian authorities, the alleged effects include:
- price undercutting;
- price depression;
- price suppression;
- lost sales;
- lost market share;
- lower margins;
- reduced capacity utilisation;
- employment impacts; and
- negative effects on investment.
These are allegations, not final findings. The investigation will determine whether dumping or subsidisation occurred and whether the imports caused or threaten to cause injury to Canadian industry.
An investigation is not the same as a final determination that dumping has occurred.
What happens next?
Canada’s trade remedy process involves both the CBSA and the Canadian International Trade Tribunal (CITT), which examine different parts of the case.
The CITT is responsible for determining whether there is a reasonable indication that the allegedly dumped or subsidised imports have caused or threaten to cause injury to Canadian producers.
A preliminary injury determination is scheduled for October 16, 2026.
The CBSA is investigating whether the products were dumped or subsidised. Its preliminary determinations are expected by November 16, 2026.
If the authorities make preliminary determinations of dumping or subsidisation and the investigation proceeds, provisional duties could become relevant.
For importers, the financial implications of the case may become clearer over the coming months.
Why should packaging buyers care about trade remedy investigations?
International packaging procurement often starts with a quotation comparison:
- Factory A: $0.18 per unit;
- Factory B: $0.21 per unit;
- Factory C: $0.24 per unit.
At first glance, choosing the lowest quotation seems straightforward. The factory price, however, is only one part of the actual procurement cost.
A more useful calculation is:
Factory price + tooling + inland transportation + freight + insurance + customs duties + taxes + customs clearance + potential trade remedies = landed cost
If anti-dumping or countervailing duties apply to a particular product, the difference between factory price and landed cost can become significant.
Professional international sourcing therefore requires buyers to assess the complete import structure rather than compare unit prices alone.
HS classification is more important than many buyers realise
Customs classification is one of the most important elements in international packaging trade. Every imported product needs to be classified under the appropriate customs tariff system.
For relatively simple products, classification may be straightforward. Packaging can be more complicated because construction, materials and intended use may influence classification.
Consider the difference between:
- a disposable paper cup;
- a folding carton;
- a corrugated shipping box;
- a rigid gift box;
- a moulded fibre food container; and
- a paperboard blank.
All of these products may be described broadly as paper packaging, but customs authorities do not necessarily treat them as the same product.
Buyers should not assume that a trade measure covering one type of paper packaging automatically applies to every paper packaging product. The precise product definition matters.
Country of origin matters too
The Canadian investigation also shows why buyers need clear origin information.
Importers should understand:
- where the packaging was manufactured;
- the country of origin;
- the exporter;
- the manufacturer; and
- the applicable customs classification.
These questions become particularly important when trade remedies are involved.
Importers should maintain accurate commercial invoices, packing lists, product descriptions and origin information. Resolving origin or classification questions only after goods arrive at customs can create unnecessary delays and costs.
Does this mean buyers should stop sourcing packaging from China?
No. A trade investigation involving a specific product category does not mean that sourcing packaging from China as a whole has become impractical.
China remains one of the world’s largest manufacturing centres for paper packaging, with capabilities across:
- folding cartons;
- rigid boxes;
- corrugated packaging;
- gift boxes;
- cosmetics packaging;
- food packaging;
- paper bags;
- paperboard displays;
- specialty finishing; and
- custom inserts.
For many international buyers, Chinese packaging manufacturers remain competitive because of manufacturing scale, supply chain depth, structural engineering capability and access to a wide range of printing and finishing processes.
The lesson from trade investigations is not to avoid China. It is to understand what you are importing.
Buyers should compare landed cost, not just unit price
A significantly lower factory price may still not represent the cheapest sourcing option.
Buyers should consider:
- freight costs;
- import duties;
- trade remedy measures;
- order quantities;
- packaging dimensions;
- shipping volume;
- tooling costs;
- quality consistency;
- lead times;
- defect rates; and
- inventory requirements.
A supplier that is slightly more expensive at the factory level may still provide a lower total cost if the packaging ships more efficiently, has fewer defects or creates fewer customs and compliance problems.
This matters especially for high-volume packaging. A small difference multiplied across hundreds of thousands or millions of units can have a significant financial impact.
Packaging design can also affect landed cost
Trade policy is not the only factor that influences imported packaging costs. The packaging structure itself can have a major effect.
Rigid boxes are usually shipped as finished three-dimensional products, so transportation may involve large amounts of empty space.
Foldable rigid boxes, folding cartons and flat-packed structures can sometimes use shipping space more efficiently.
A packaging engineer may therefore reduce total procurement costs by redesigning the structure instead of simply cutting the manufacturing price.
Buyers should consider questions such as:
- Can the box be shipped flat?
- Can the dimensions be reduced?
- Can the insert be redesigned?
- Can more units fit into each export carton?
- Can the packaging maintain protection with less material?
- Can container utilisation be improved?
These changes can sometimes create greater savings than negotiating a few cents from the factory price.
Diversification is becoming part of packaging procurement
Global supply chains have experienced repeated disruptions over the past several years, including:
- trade disputes;
- shipping disruptions;
- energy price volatility;
- material shortages;
- regulatory changes; and
- geopolitical uncertainty.
Many international brands are reconsidering how their supply chains are structured. For large packaging programmes, some companies may maintain multiple approved suppliers or production locations.
This does not necessarily mean moving production away from an existing supplier. It means avoiding dependence on a single sourcing route when packaging is critical to product availability.
For example, a company might maintain:
- a primary packaging supplier;
- an alternative supplier;
- approved substitute materials;
- backup structural specifications; and
- alternative shipping routes.
This approach can provide more resilience when market conditions change.
What should Canadian packaging importers do now?
Companies importing relevant paperboard cups or containers from China should follow the investigation closely.
The first step is to determine whether the imported products fall within the official product definition.
Buyers should review:
- product construction;
- paperboard specifications;
- customs classification;
- country of origin;
- manufacturer and exporter information;
- commercial documentation; and
- import volumes.
Importers dealing with potentially affected goods should obtain professional customs or trade advice where necessary rather than rely solely on supplier descriptions.
For packaging products outside the scope of the investigation, the case is still a reminder to maintain accurate product documentation.
What should packaging manufacturers learn from this?
The investigation sends a practical message to packaging manufacturers. International buyers increasingly need more than a quotation and a finished product. They need accurate information.
A professional packaging supplier should be able to describe clearly:
- what the packaging is made from;
- how it is manufactured;
- its dimensions and weight;
- its intended application;
- its country of manufacture;
- the materials used for inserts and components; and
- relevant technical specifications.
The final customs classification is a customs matter and should be confirmed by the importer or an appropriate customs professional.
Manufacturers can make that process easier by providing accurate and detailed product information.
Transparency is becoming part of packaging supply
International packaging trade is becoming more complex. Environmental regulations are becoming stricter, Extended Producer Responsibility requirements are expanding, material documentation is becoming more important, and trade remedy investigations continue to affect certain product categories.
In this environment, transparency matters more in the relationship between packaging manufacturers and buyers.
The cheapest supplier is not necessarily the supplier offering the lowest quotation. A reliable supplier also helps buyers understand exactly what they are purchasing.
Final thoughts
Canada’s investigation into certain Chinese paperboard cups and containers is still at an early stage. The launch of the investigation does not establish a final conclusion.
The case does, however, show that international packaging procurement involves more than finding a factory and negotiating a unit price.
Product classification, country of origin, trade policy, logistics, packaging design and accurate documentation can all affect the result.
For brands sourcing custom paper packaging internationally, the best procurement strategy is not simply to find the lowest FOB price. Buyers also need to understand the total landed cost, regulatory environment and supply chain risks behind each packaging decision.
As global packaging trade becomes more complex, informed sourcing will matter as much as good packaging design.
