For businesses shipping freight and importing goods into Canada, timing matters. And not just when it comes to transportation. Timing when you pay duties and taxes matters, too.

Paying duties and taxes before imported inventory is needed for the Canadian market can tie up working capital. Canada Border Services Agency (CBSA) bonded warehouses give qualifying importers another option. These special storage facilities can let you store imported goods under customs control and, with some exceptions, defer applicable duties and taxes until those goods are released for Canadian consumption or exported.

Here’s what importers, exporters, and shippers should know about CBSA bonded warehouses in Canada.

What Is a Customs Bonded Warehouse in Canada?

What is a Bonded Warehouse in Canada

A customs bonded warehouse (CBW) is a facility licensed and regulated by the Canada Border Services Agency (CBSA) but operated by the private sector.

Goods stored in a CBW have entered Canada, but they have not yet been released by the CBSA into the Canadian economy. This allows certain customs duties, anti-dumping and countervailing duties, excise duties and taxes, GST (Goods and Services Tax),  and HST (Harmonized Sales tax) to remain deferred, subject to applicable exceptions, while the goods remain properly warehoused.

There are two general types of CBSA bonded warehouses in Canada:

  1. Private bonded warehouses, operated to store the operator’s own in-bond goods
  2. Public bonded warehouses, operated to store goods belonging to multiple importers

A bonded warehouse is a physical, licensed place. A warehouse, office area or other premises does not become “bonded” simply because unreleased imported goods are stored there. The proposed location must meet CBSA licensing, security, access, examination, and recordkeeping requirements.

How Does a CBSA Bonded Warehouse Work?

The basic process looks like this:

  1. Goods are imported into Canada.
  2. The goods are entered into a licensed customs bonded warehouse while remaining under CBSA control.
  3. Applicable duties and taxes remain deferred, subject to program rules, and commodity-specific requirements.
  4. The goods can remain in storage or undergo certain specifically permitted activities.
  5. When goods are released for Canadian domestic consumption, applicable duties, and taxes become payable.
  6. If qualifying goods are instead exported from Canada, Canadian duty relief may apply, subject to any relevant restrictions or special measures.

The key trigger is release into the Canadian market, not the sale of the goods. In fact, ownership of goods can change while they remain inside a bonded warehouse. 

Canadian regulations specifically provide for transfers of ownership while goods remain warehoused, provided the required customs documentation is completed. That makes CBWs particularly useful for businesses that want to carry inventory in Canada without necessarily releasing all of it into the domestic market at once.

How Are Duties on Bonded Goods Calculated?

Using a bonded warehouse does not change the underlying rules used to determine what an importer owes.

Canadian customs duties can depend on several factors, including:

  • Tariff classification
  • Country of origin
  • Applicable tariff treatment
  • Value for duty
  • Free trade agreement eligibility
  • Surtaxes or other trade measures
  • Commodity-specific rules, quotas, or permits

An item is not automatically subject to customs duty simply because it comes from a country without a Canadian free trade agreement (FTA). The applicable rate depends on the tariff treatment and classification of the specific goods.

Duties are also not calculated using the manufacturer’s suggested retail price (MSRP).

For many commercial transactions, Canada’s primary customs valuation method is the transaction value method. When its requirements are met, the duty is based on the price paid or payable for goods sold for export to Canada to a purchaser in Canada, with applicable additions or deductions under Canadian customs valuation rules. Other valuation methods may apply when transaction value cannot be used.

It’s important to know that bonded storage does not automatically exempt goods from surtaxes or other additional trade measures that may apply when the goods are released. Importers should evaluate the measures in effect at the time of release rather than assume that bonded status or eligibility eliminates an otherwise applicable tariff.

What Are the Benefits of Using a Customs Bonded Warehouse?

The biggest advantage is usually cash flow.

Rather than paying eligible duties and taxes on an entire shipment immediately and then carrying that expense while inventory sits in storage, an importer can generally defer payment until goods are actually released into the Canadian market.

For example, a company importing 5,000 units may not need to release all 5,000 at once. A bonded warehouse can allow the importer to store inventory and release portions as needed.

Other benefits of using a customs bonded warehouse include inventory flexibility, re-export flexibility, and secured storage. Here’s how those benefits work.

Better Inventory Flexibility

Importers can bring inventory into Canada earlier without necessarily releasing it all into domestic commerce immediately. That can help businesses manage seasonal demand, bulk imports, distribution schedules, and just-in-time inventory.

Storage for Goods Intended for Re-Export

A CBW can also be useful when imported goods are ultimately intended for another market rather than Canadian consumption. Canadian duties may not ultimately be payable when qualifying goods are exported rather than released into Canada, although CUSMA rules and other program-specific exceptions can affect that treatment.

Secure, Controlled Storage

Security is not simply an optional feature provided by higher-end warehouse operators.

Licensed bonded warehouses are required to maintain secure storage and controls over access to the bonded premises. Regulations include requirements addressing sturdy construction, secure doors and windows, restricted access, inventory identification, and procedures for protecting the warehouse.

Individual warehouse providers may offer additional security measures or insurance benefits, but those are provider-specific rather than guaranteed benefits of the CBW program itself.

What Can You Do to Goods in a Bonded Warehouse?

what changes can be made to goods in a bonded warehouse

This is one area where a bonded warehouse is very different from a general manufacturing or processing facility. Goods in a bonded warehouse cannot simply be transformed however an importer chooses.

The Customs Bonded Warehouses Regulations specify the activities that can be performed while goods remain in the warehouse. 

Permitted activities include:

  • Displaying
  • Inspecting
  • Testing
  • Marking, labelling, tagging or ticketing
  • Packing, unpacking, packaging, and repackaging
  • Storing
  • Removing representative samples for soliciting orders
  • Disassembling or reassembling goods when necessary for packing, handling, or transportation

Certain additional activities are permitted only when they do not materially alter the characteristics of the goods, including:

  • Cleaning
  • Diluting
  • Normal maintenance or servicing
  • Preserving
  • Separating defective goods from prime-quality goods
  • Sorting or grading
  • Trimming, filing, slitting or cutting
  • Making changes necessary to comply with applicable Canadian or provincial law

The important distinction is not whether an activity “adds value.” The regulations instead identify what activities are permitted and, for several of them, require that the characteristics of the goods are not materially altered.

If your business needs to manufacture or substantially process imported goods before exporting them, another Canadian duty-deferral program may be a better fit.

Are Some Goods Subject to Special Bonded Warehouse Rules?

Yes. Being admissible into Canada does not automatically mean a product can be handled in a customs bonded warehouse in the same way as other commercial goods.

Canadian regulations contain special rules for products including:

  • Intoxicating liquor
  • Tobacco and tobacco products
  • Spirits and wine
  • Vaping products
  • Specially denatured alcohol

For example, a bonded warehouse generally needs the appropriate provincial authorization to receive or transfer intoxicating liquor. Imported tobacco products, packaged spirits, wine, and vaping products also have specific restrictions governing when and why they may enter or leave a bonded warehouse.

Importers should confirm both admissibility and CBW eligibility before planning a warehousing strategy for regulated commodities.

How Long Can Goods Stay in a CBSA Bonded Warehouse?

For most commercial goods, the maximum storage period is four years.

However, Canadian regulations establish different deadlines for specific categories.

Imported GoodsGeneral Time Limit
Spare parts for aircraft or vessels, oceanic cable, oil-drilling supplies and related equipment not intended for domestic consumption15 years
Beer and wine5 years
Goods warehoused for prescribed marking or display at conventions, exhibitions, or trade shows90 days
Most other goods4 years

The clock does not simply begin when a forklift moves the shipment into the physical warehouse. Under the regulations, the applicable period begins on the date the goods are described on the prescribed customs form.

There is also a separate five-year rule for tobacco products, packaged spirits, and vaping products. Those prescribed goods can be forfeited if they remain in the bonded warehouse beyond the applicable five-year period.

Extensions may be available in certain extenuating circumstances, but they should not be treated as automatic. CBSA guidance says a request should be made before the applicable storage deadline expires.

One more timing consideration: Goods subject to a tariff rate quota (TRQ) may require a valid shipment-specific import permit when they leave the bonded warehouse to qualify for the applicable within-access rate. For goods stored long term, importers should make sure permit eligibility still applies when the goods are ultimately released.

How Much Does it Cost to Use a CBSA Bonded Warehouse?

There is no single standard price for storing freight in a customs bonded warehouse.

For an importer using a third-party facility, costs can vary based on factors such as:

  • Amount of storage space required
  • Length of storage
  • Handling requirements
  • Commodity type
  • Receiving and outbound activity
  • Inventory management
  • Insurance
  • Additional services such as labelling or repackaging

Those commercial storage charges should not be confused with the financial security requirement imposed on bonded warehouse operators.

CBSA guidance states that the operator’s security is generally set at 60% of the maximum duties and taxes that would otherwise be payable at any time during the year following issuance of the licence. That security is reviewed at least annually and may be adjusted.

In other words, the CBSA security requirement is not a 60% surcharge on the duties owed for each customer’s shipment.

Customs Bonded Warehouse vs. Sufferance Warehouse

These two facilities both hold goods under customs control, but they serve different purposes.

A sufferance warehouse is primarily a short-term facility used to hold and examine in-bond goods while they are waiting for CBSA release or export.

A customs bonded warehouse, on the other hand, is part of Canada’s Duty Deferral Program and is intended for longer-term storage of imported goods before they are released into the Canadian market or exported.

A shipper should not use the terms interchangeably.

What Is Bonded Cargo?

“Bonded cargo” or “in-bond goods” describes the customs status and authorized movement of unreleased freight, not admission into a customs bonded warehouse.

Bonded carriers can move unreleased goods beyond the first point of arrival or between authorized points in Canada while the shipment remains under customs control. A common example is moving goods inland for release at a CBSA office or sufferance warehouse rather than completing the process at the first point of arrival. That is a transportation authorization.

A CBSA customs bonded warehouse licence, by comparison, governs the place where goods can be stored under the CBW program.

The words sound similar because both involve customs security and unreleased goods, but they are not the same program.

Is a Customs Bonded Warehouse the Same as a Canadian FTZ?

Not exactly. And Canada's approach to foreign trade zones differs from the traditional model used in some other countries.

Canada does not rely on geographically restricted foreign trade zones where businesses receive customs treatment simply because they operate inside a particular boundary.

Instead, Canada offers geographically flexible FTZ-type programs. The federal government identifies the Duty Deferral Program as Canada's primary FTZ-type program, and customs bonded warehouses are one component of it.

The three Duty Deferral Program components are:

  • Customs Bonded Warehouse Program
  • Duties Relief Program
  • Duty Drawback Program

That means a customs bonded warehouse should not be thought of as an alternative to entering a physical Canadian “FTZ zone.” It is itself one of the programs Canada uses to provide many of the customs benefits that traditional FTZs provide elsewhere.

How Does CUSMA Affect Bonded Warehouse Strategy?

CUSMA replaced NAFTA on July 1, 2020, so references to NAFTA certificates or NAFTA-era requirements should no longer be used for current Canada-U.S.-Mexico trade.

Under CUSMA, qualifying goods can receive preferential tariff treatment when the rules of origin and other requirements are met. CUSMA does not require a prescribed certificate form; instead, a certification of origin must contain the required minimum data elements and may appear on an invoice or another document.

There is another wrinkle for businesses combining bonded warehousing with re-export.

CUSMA can limit duty relief or drawback in certain situations involving non-originating goods that are used in the production of another product and then exported to the United States or Mexico. Goods exported in the same condition and CUSMA-originating goods are among the categories that can receive different treatment under those rules.

So “we're exporting it instead of selling it in Canada” should not be treated as the end of the tariff analysis.

Should You Use a CBSA Bonded Warehouse?

A CBSA bonded warehouse can be a useful tool when your supply chain involves imported inventory that does not need to enter the Canadian market immediately.

It may make sense if your business:

  • Imports large quantities but releases inventory gradually
  • Needs longer-term storage for unreleased goods
  • Imports goods that may ultimately be re-exported
  • Wants to defer eligible duties and taxes while inventory remains under customs control
  • Needs to perform limited activities such as testing, labelling, or repackaging before release
  • Is evaluating multiple Canadian duty-deferral options

But bonded warehousing is not a universal shortcut around import duties. Classification, origin, valuation, permits, CUSMA rules, surtaxes and the eventual destination of the goods can all affect the final result.

The best strategy starts by understanding what the goods are, where they're coming from, what will happen to them in Canada and where they're going next.

Shipping Freight Into and Across Canada

Customs compliance is one part of a successful cross-border shipment. The freight still has to move efficiently between the shipper, border, warehouse, consignee, and any other locations involved in the supply chain.

R+L Global Logistics helps businesses coordinate freight moving between the United States and Canada, including full truckload, less-than-truckload, temperature-controlled, and expedited shipments.

When a shipment involves bonded movement, customs warehousing or specialized import requirements, the right transportation plan should be coordinated with the appropriate customs broker, warehouse operator, and other trade partners from the beginning.

That helps avoid a familiar cross-border problem: having the freight ready to move while the paperwork, permits, or customs strategy are still trying to catch up.

  1. I am currently evaluating the prospect of bringing vitamin supplements in to Canada from the U.S. to sell within Canada.

    Are there any import methods where by the importer can 'reduce' import costs, duty taxes that ultimately passed on to the end customer.

    For the purpose of selling vitamin supplements into Canada, what is the most efficient and cost effective method to warehouse this category? Is it best to use a FTZ warehouse to repackage (if there could be a associated cost savings).

    Can you forward a cost schedule for warehousing goods in a bonded warehouse?

    Does your company handle fulfillment for warehoused goods?

    Can you forward a cost schedule for your fulfillment services.

    Thank you, Estee

  2. We have been exporting products from Canada to Peru for over 5 years now. The product manufacturer would like to move to a 3PL system and has asked us to locate a customs bonded warehouse. One of the services we received and paid for before is labelling and we are interested in a quote for warehousing and labelling services. We are not a large company.
