Highway tanks: containment evidence in Canada
Identify the cargo, vessel and applicable containment requirements together. A component marking cannot establish the tank’s certification.
Start with the intended contents
Record the product classification and intended service before choosing a tank. Transport Canada’s highway-tank guidance distinguishes construction and inspection requirements from selection and use requirements. A sanitary or food-grade product description does not establish dangerous-goods suitability.
- Product classification
- Intended service
- Vessel identity
- Applicable current requirements
Read vessel and component evidence separately
Obtain the tank’s compliance information and applicable inspection records. A relief-valve description, pump model or hose marking is evidence about that component. It must not be promoted into a vessel code or an approval for the complete containment system.
- Vessel markings
- Component identities
- Inspection and test records
- Unresolved code or service claims
Confirm the applicable standard and edition
Transport Canada identifies CSA B620 for highway-tank construction and inspection and separate B621/B622 selection-and-use frameworks. Consult the current official guidance and qualified containment expertise for the cargo and equipment involved. Publication of a newer edition alone does not establish that every provision is already in force.

- Applicable edition and incorporation
- Cargo-specific selection
- Qualified containment review
