Why proof matters now
Since September 22, 2025, Canada treats non-US steel as melted in China until you show a certificate.
Surtax on value for duty
25%
Owed on scheduled steel and aluminum imports when the importer cannot produce a certificate of melt or smelt origin on request.
Source: SOR/2025-154US Section 232 duty
50%
Charged on the full customs value of covered metal articles since April 6, 2026, with country of melt and pour reported on every entry.
Of origin records
7 years
Buy Canadian contractors must keep complete material origin records. CBSA expects six years for every import.
CBSA opened a verification priority on the surtax in April 2026 and found errors in half of its first closed cases.

People confirm origin
Origin fields are always confirmed by a person before sign-off.
No tool can do that for you. Ocel runs an evidence check against each rule, shows the gaps it finds, and tells you when a pack is ready to submit. The person who signs an attestation stays responsible for it.
Mill test certificates first, including steel melt and pour and aluminum smelt and cast details. Supplier declarations, CUSMA certifications of origin and chain-of-custody records can sit alongside them in the same pack.
No. Each request is a private link. Suppliers open it, upload their certificates and are done. You see every upload the moment it lands.
In Canada. Files and extracted data are stored in the Canada Central region and certificates are read on servers in Montreal. We never send your documents to outside AI or analytics services.
Yes. Share a proof pack with your broker through an expiring link, or invite them to review entries with you. Brokers can also run Ocel for their own clients.
The checks start with Canada's steel and aluminum surtax, US Section 232 melt and pour reporting, CUSMA and Buy Canadian. We track EU rules such as CBAM and add checks as obligations take effect.
