Importing Industrial Chemicals into Canada: WHMIS, SDS, Customs and Documents

Buying industrial chemicals from overseas can cut costs considerably, but a shipment that arrives without the right labels, safety data sheets or customs paperwork can sit at the port while storage charges add up.

This guide covers what a Canadian importer needs to get right, from WHMIS 2015 to CBSA customs, so the first order clears smoothly. It is written for buyers of industrial, water-treatment and agricultural chemicals such as sulphuric (sulfuric) acid, caustic soda, PAC, alum and fertilizer salts.

This is general guidance, not legal advice. Rules change and depend on the product and quantity — always confirm the details for your shipment with your customs broker.

1. WHMIS 2015: labels and safety data sheets

Canada's hazard-communication system is WHMIS 2015, set out in the Hazardous Products Act and Hazardous Products Regulations. It is aligned with the Globally Harmonized System (GHS), so a good GHS safety data sheet is the right starting point — but Canada adds its own requirements.

• A hazardous product sold or imported for use in a Canadian workplace needs a WHMIS-compliant supplier label and safety data sheet (SDS).
• Both must be available in English and French.
• The SDS follows the standard 16-section format, from identification and hazards through to transport and regulatory information.
• As the importer, you are responsible for making sure a compliant label and SDS are in place — as the supplier if you resell the product, or as the employer if you use it in your own workplace.

What to do: ask your overseas supplier for the SDS before you place the order, not with the shipment. Your WHMIS consultant or broker can then confirm whether it needs adapting for Canada, and have the French version and Canadian labels prepared in time. See our guide to what to check in an SDS.

2. Is the substance allowed? DSL and precursor checks

Domestic Substances List

Under the Canadian Environmental Protection Act, 1999, a chemical substance that is not on the Domestic Substances List (DSL) is treated as "new" and must be notified before it is imported above certain quantities. Common industrial chemicals — sulphuric acid, caustic soda, soda ash, alum and most fertilizer salts — are long-established and listed, but check the CAS number of anything unusual, especially blends and specialty products.

Precursor chemicals

Some everyday industrial chemicals are also listed precursors in Canada, because they could be diverted to make illegal drugs. Sulphuric acid, hydrochloric acid, acetone and toluene appear on Schedule VI of the Controlled Drugs and Substances Act. Depending on the class of precursor and the quantity, registration, permits or record-keeping may apply to importers. Ask your broker to confirm this for your product before the first order.

3. Customs: CBSA, CARM, tariff classification and duties

Get set up before the shipment leaves

• Business Number with an import–export (RM) program account from the Canada Revenue Agency.
• CARM registration. CBSA's Assessment and Revenue Management (CARM) client portal is how importers account for and pay duties and taxes. Importers who want goods released before paying usually need financial security (a bond) registered in CARM.
• A licensed customs broker, who can file the entry for you. For dangerous goods, choose one with chemical experience.

Classification, duties and taxes

Every product is classified with a 10-digit code in the Customs Tariff, which builds on the international HS code on our invoice — sulphuric acid, for example, falls under HS 2807. The classification decides the duty rate. India and Canada do not have a free-trade agreement in force, so goods from India pay the most-favoured-nation (MFN) rate for their tariff line. GST is charged at the border on top. Your broker will confirm the exact rates for each product.

Documents your broker will ask for

• Commercial invoice — or a Canada Customs Invoice — with the full product description, HS code, quantities, value, currency and Incoterms
• Packing list with the number and type of packages, and net and gross weights
• Bill of lading (sea) or air waybill
• Certificate of origin
• SDS and the dangerous-goods declaration for hazardous products
• Certificate of analysis (COA) for the lot — not always needed for customs, but essential for your quality check. See how to read a COA

4. Shipping dangerous goods to Canada

Corrosive chemicals such as sulphuric acid (UN 1830, Class 8) travel by sea under the IMDG Code. Once they land, moving them by road or rail within Canada falls under the Transportation of Dangerous Goods (TDG) Regulations, which cover classification, labels, placards, shipping documents and training. Depending on the product and quantity, an Emergency Response Assistance Plan (ERAP) may also be needed — your carrier or broker can confirm.

Practical points:

• UN-approved packaging. Liquids such as sulphuric acid are often shipped in composite IBCs marked with a UN packaging code (for example 31HA1), which shows the container is approved for liquid dangerous goods. Check that the marks match the product.
• Labels and placards — Class 8 corrosive diamonds and the UN number on every package and on the container.
• Secure stowage — IBCs stretch-wrapped, strapped and braced so they cannot shift on the voyage.
• Ports. Containers from India usually arrive at Vancouver or Prince Rupert on the west coast, or Montreal and Halifax in the east. Sea transit is typically several weeks, so plan stock accordingly.

5. Food products and fertilizers

If you also import agro products — spices, rice, pulses or dehydrated onion — you need a Safe Food for Canadians (SFC) licence from the CFIA, as well as preventive-control and traceability records. Fertilizers such as ammonium sulphate or zinc sulphate must either be registered under the Fertilizers Act or meet the conditions for an exemption, and their labels must meet CFIA requirements.

6. What to ask your supplier for

When you request a quote from an overseas chemical supplier, ask for:

1. The SDS for the exact product and grade — before you order
2. A COA from a recent lot, and confirmation that every lot ships with its own COA
3. The HS code, UN number, hazard class and packing group
4. The packaging type and its UN approval marks
5. The Incoterm (FOB, CFR or CIF) and the port of loading
6. Who prepares the dangerous-goods declaration and the other shipping documents
