Canada’s 2026 Paperboard Cup Investigation: What Importers Should Know About Bagasse Packaging
Last updated: November 11, 2026
Canada's foodservice packaging market is facing a new trade development that importers of disposable cups and food containers should monitor closely.
On November 9, 2026, the Canada Border Services Agency (CBSA) announced an extension to its preliminary investigations into the alleged dumping and subsidizing of paperboard cups and containers originating in or exported from China.
The preliminary phase has been extended from 90 days to 135 days. The CBSA will now make its preliminary determinations, or terminate the investigations with respect to some or all of the goods, on or before December 30, 2026.
For importers, this is more than a change in a regulatory calendar. It is a reminder that product material, manufacturing process, country of origin and customs classification can have a direct impact on sourcing decisions.
An especially important distinction for the food packaging industry is that the current Canadian investigation expressly excludes molded fiber products.
This matters to buyers evaluating sugarcane bagasse packaging as part of their foodservice product range.
1. What Changed in Canada's Paperboard Cup Investigation in November 2026?
The CBSA initiated the investigation on August 17, 2026, under Canada's Special Import Measures Act (SIMA).
The investigation examines allegations that certain paperboard cups and containers from China are being dumped or subsidized and that these imports have caused injury to Canadian producers.
The latest timeline is as follows:
Date | Development |
August 17, 2026 | CBSA initiated the dumping and subsidy investigations |
October 16, 2026 | CITT found a reasonable indication of injury to the Canadian industry |
November 9, 2026 | CBSA extended the preliminary investigation period |
December 30, 2026 | New deadline for preliminary determinations or termination |
The October 16 decision by the Canadian International Trade Tribunal (CITT) was a preliminary injury determination. It allowed the investigation to continue, but it was not a final decision that duties must be imposed.
Does the November 9 extension mean that new duties have been imposed?
No.
The extension notice does not itself impose anti-dumping or countervailing duties.
The CBSA must first complete its investigation and issue the relevant preliminary determination. Depending on the findings, provisional measures may follow under Canada's trade-remedy procedures.
Importers should therefore distinguish between:
An investigation being initiated.
A preliminary determination being issued.
Provisional duties becoming applicable.
Final trade-remedy decisions being made.
These are separate stages.
For Canadian buyers, the immediate priority is to review existing purchase commitments, planned shipments and supplier information rather than assume that a new duty rate already applies.
2. Which Paperboard Cups and Containers Are Covered?
Understanding the product scope is one of the most important parts of this investigation.
According to the CBSA's Statement of Reasons, the subject goods are:
Paperboard cups and containers rolled from coated paperboard stock.
Blanks or flats used to form those paperboard cups and containers.
Products originating in or exported from China.
The definition excludes enhanced clay-coated paperboard stock and paperboard cups or containers packaged in party sets containing other types of tableware.
Typical products within the scope
The investigation covers common foodservice formats such as:
Hot beverage paper cups.
Cold beverage paper cups.
Single-wall and double-wall paper cups.
Rolled paperboard soup containers.
Rolled paperboard takeaway food containers.
Cut paperboard blanks ready to be formed into cups or containers.
The CBSA describes paperboard cups as commonly available in sizes from approximately 4 oz to 32 oz, while the covered paperboard food containers generally range from approximately 2 oz to 40 oz.
These are descriptions of typical products, not a substitute for reviewing the formal product definition.
Does a plastic or PLA coating change the scope?
Not automatically.
The CBSA explains that these paperboard products are commonly made from coated paperboard. The coating may be polyethylene (PE) or another material, such as PLA, to provide a moisture, grease or temperature barrier.
Therefore, a PLA coating alone does not automatically remove a rolled paperboard cup or container from the investigation.
The full product construction and written scope must be reviewed.
3. Which Products Are Excluded From the Investigation?
The CBSA's product definition and Statement of Reasons identify several important exclusions.
Product type | Current investigation status |
Rolled coated paperboard cups | Included if they meet the scope |
Rolled coated paperboard food containers | Included if they meet the scope |
Die-cut blanks ready for forming | Included |
Enhanced clay-coated frozen-food containers | Excluded |
Folded paperboard food pails | Excluded |
Molded fiber products | Excluded |
Certain paperboard party sets containing other tableware | Excluded |
Uncut printed paperboard rolls | Not subject goods under the described definition |
The distinction between rolled paperboard containers and molded fiber packaging is particularly important.
They may both be used for takeaway food, but their materials and manufacturing processes are different.
4. Why the Molded Fiber Exclusion Matters for Bagasse Packaging
Sugarcane bagasse is the fibrous residue left after sugarcane juice extraction.
After processing into pulp, it can be molded into rigid foodservice packaging such as:
Plates.
Bowls.
Hinged clamshell containers.
Multi-compartment meal trays.
Takeaway food boxes.
These products belong to the molded fiber packaging category rather than the conventional rolled coated-paperboard category.
The CBSA's Statement of Reasons expressly states that the investigation does not include molded fiber products. It discusses the differences between coated paperboard products and molded fiber products, including their manufacturing processes and physical characteristics.
Does this mean bagasse packaging is outside the current Canadian investigation?
For conventional bagasse molded-fiber products that meet the excluded product description, the answer is that they are not described as subject goods in this particular Canadian paperboard investigation.
However, importers should not treat this as a blanket exemption for every product marketed as bagasse or eco-friendly packaging.
The actual product construction and manufacturing process matter.
For example, buyers should distinguish between:
A rolled paperboard cup with a coating.
A molded sugarcane fiber bowl.
A molded fiber takeaway container.
A paperboard container formed by rolling.
A paperboard food pail formed by folding.
These formats may serve similar foodservice applications, but they are not necessarily treated the same way under a trade-remedy investigation.
Why product names are not enough
A product catalogue may describe an item as a “compostable food container” or “eco-friendly takeaway box”.
That description does not provide enough technical information to establish its customs treatment.
Buyers should request:
Main material composition.
Product construction.
Manufacturing process.
Product drawings and dimensions.
Surface coating or treatment information.
Actual country of manufacture.
Applicable customs classification.
The written product definition is more important than the commercial name or a tariff code alone.

5. Canada and the United States: Different Trade Rules for Molded Fiber Products
Importers should also avoid assuming that the Canadian investigation and the U.S. trade-remedy orders cover the same products.
The two markets have separate proceedings and different product scopes.
The current Canadian investigation focuses on certain rolled coated-paperboard cups and containers from China and expressly excludes molded fiber products.
The United States, by contrast, has separate anti-dumping and countervailing duty orders covering certain thermoformed molded fiber products from China and Vietnam.
For buyers importing bagasse tableware into the United States, fiber source alone does not determine whether a product is covered.
MANA ECO has published a separate guide explaining the U.S. molded fiber trade-remedy issue:
The key lesson is simple:
A product's treatment in one country should never be used as a substitute for checking the applicable trade-remedy scope in another country.
6. What Canadian Importers Should Do Before Their Next Purchase Order
For distributors, wholesalers and foodservice packaging importers, the investigation is a good reason to improve product-level sourcing checks.
1. Review every SKU separately
Do not classify an entire catalogue as “paper packaging” or “eco packaging”.
Separate products by:
Material.
Structure.
Manufacturing process.
Intended application.
Country of origin.
This makes it easier to identify which items may fall within a specific investigation.
2. Confirm the actual manufacturing process
Ask suppliers whether the product is:
Made from coated paperboard.
Rolled and sealed into its final shape.
Formed by folding paperboard.
Molded from cellulose fiber.
Produced using heated molds.
Dried or cured in a mold.
A clear process description is particularly important when comparing paperboard products with molded fiber packaging.
3. Verify the country of origin
The Canadian investigation concerns products originating in or exported from China.
Buyers should confirm the actual manufacturing country and the legal identity of the producer and exporter.
Changing a shipping route or using a different trading company should not be treated as a reliable way to change the product's origin or trade-remedy status.
4. Do not rely on the HS code alone
The CBSA lists tariff classifications 4823.69.00.10 and 4823.69.00.90 as usual classifications for the allegedly dumped and subsidized goods.
However, the agency also explains that these codes may cover non-subject products and that subject goods may be imported under other codes.
The written product definition remains authoritative.
Importers should work with their Canadian customs broker or trade counsel to review the actual product.
5. Recalculate the landed cost
A competitive FOB price does not always translate into a competitive landed cost.
Buyers should consider:
Cost item | What to check |
FOB product price | Supplier's latest quotation |
Ocean freight | Current freight rate and route |
Ordinary customs duty | Applicable tariff classification |
AD/CVD exposure | Whether the product falls within a trade-remedy order |
Customs clearance | Broker and handling charges |
Warehousing | Storage and distribution costs |
Inventory risk | Potential delays or additional costs |
Avoid building a quotation around an assumed anti-dumping rate before the CBSA has issued the relevant determination.
6. Review purchase contracts
For orders that may be affected by trade-remedy measures, buyers should clarify:
Which party is responsible for customs classification.
Which party provides origin documents.
How additional duties or regulatory changes are handled.
Whether prices can be reviewed if import costs change.
What happens if a shipment is delayed by customs review.
These points can reduce disputes between importers and suppliers.
7. Monitor the December 30 deadline
The next important date is December 30, 2026.
Importers should monitor the CBSA's official investigation page for preliminary determinations, termination notices or further procedural updates.
A change in the investigation schedule should be reflected in procurement planning and landed-cost calculations.
7. When Should Buyers Consider Bagasse Food Packaging?
The Canadian investigation also provides an opportunity for buyers to review their overall foodservice packaging mix.
Sugarcane bagasse packaging can be considered for certain applications where a rigid fiber-based product is suitable.
Application | Product to evaluate |
Takeaway meals | Bagasse clamshell containers |
Restaurant food portions | Bagasse bowls |
Catering and institutional meals | Bagasse trays |
Burger and fast-food packaging | Hinged bagasse containers |
Food presentation | Bagasse plates |
For takeaway meals and food delivery applications, buyers can explore different bagasse clamshell containers, including single-compartment and multi-compartment designs.
However, bagasse is not a universal replacement for every paperboard or plastic product.
For example, a hot beverage paper cup and a molded fiber meal container perform different functions. Buyers should not assume that a bagasse product can replace a paper cup without considering the intended use.
Before changing materials, importers should evaluate:
Food type and temperature.
Oil and moisture resistance.
Product rigidity.
Lid compatibility.
Stacking and storage.
Transportation and delivery conditions.
Food-contact documentation.
Applicable compostability or environmental certifications.
Samples should be tested with the actual food application before a large-volume purchase.
A compostability certificate also does not automatically establish customs treatment or exemption from a trade-remedy measure.
8. Frequently Asked Questions
Are anti-dumping duties on Chinese paperboard cups already in force in Canada?
The CBSA's November 9, 2026 notice extended the preliminary investigation period to December 30, 2026. The extension itself did not impose duties. Importers should check the latest CBSA notice for any subsequent preliminary determination and effective date.
Are all Chinese paper cups covered by the investigation?
No. The investigation covers paperboard cups and containers that meet the written product definition. Product construction and origin must be reviewed individually.
Are bagasse containers included in the Canadian paperboard cup investigation?
Molded fiber products are expressly excluded from the current investigation's scope. Conventional bagasse molded-fiber products are therefore distinct from the covered rolled coated-paperboard products. Importers should still confirm the actual product construction and classification.
Does a PLA coating automatically exclude a paperboard cup?
No. The CBSA describes coated paperboard products using PE or similar coatings, including PLA. A PLA coating alone does not automatically remove a product from the investigation.
Are products from countries other than China covered?
This particular investigation concerns goods originating in or exported from China. It should not be interpreted as a general anti-dumping measure on all imported paperboard cups from every country.
Can an HS code confirm whether a product is subject to the investigation?
No. The CBSA states that tariff classifications are provided for reference and that the written product definition is authoritative. Importers should obtain product-specific customs advice.
Should Canadian buyers switch from paperboard to bagasse immediately?
Not necessarily.
The right decision depends on the food application, product performance, regulatory requirements, landed cost and availability of reliable supply. Bagasse may be suitable for certain meal containers, trays and takeaway applications, but buyers should test the selected product before changing their procurement program.
