Steel derivative goods surtax: third revision in seven months

The notice that keeps changing

CBSA published Customs Notice 25-33 on December 24, 2025, introducing a surtax on certain steel derivative goods effective December 26. That notice was updated July 17, 2026. Now it’s updated again, July 22. If your broker is still using the December filing logic, or missed the July 17 revision, your entries are landing wrong and you’re either overpaying or sitting on AMPS exposure.

The surtax itself is straightforward in concept: the government wants to address global steel overcapacity and transshipment risk by applying an additional levy on derivative goods made from steel subject to safeguard measures. But the HS scope, the calculation stacking order, and the CAD line-item mechanics have shifted with each revision. That’s the operational problem.

What counts as a steel derivative good

The order targets finished or semi-finished goods where the primary input is steel subject to SIMA or safeguard duties. Common categories: certain fasteners, wire products, tube and pipe fittings, fabricated structural components. The HS chapter spread is wide—anywhere from Chapter 73 (articles of iron or steel) through certain headings in 82, 83, 84, and beyond if the tariff classification binds to a steel input.

If your goods fall under an HS heading that was already subject to SIMA AD/CVD (antidumping or countervailing duty), the surtax can stack on top. That means you’re now managing three duty layers: MFN or preferential tariff, SIMA margins if applicable, and the derivative surtax. Miss one in your CAD filing and CBSA’s post-release verification will catch it, usually six to eighteen months later when the leverage to argue is gone.

The July 22 update clarifies which specific HS subheadings are in scope and which are carved out. The December version had importers filing conservatively—when in doubt, declare and pay. The July 17 revision narrowed some categories but left ambiguity on origin interplay (does a CUSMA-originating good escape the surtax if the steel input was non-originating?). The July 22 text appears to close that gap, but we’re still waiting for D-memo guidance.

Filing mechanics: where the surtax goes on a CAD

The surtax is not a line 38 adjustment and it’s not rolled into your SIMA duty field. CBSA wants it reported as a separate duty type on the CAD. If you’re using a legacy template that auto-populates duty fields based on the HS heading and SIMA flag, it won’t pick this up. You need a manual surtax line, calculated as a percentage of the customs value (the notice specifies the rate—typically 25% on the applicable portion of the transaction value).

That creates a filing trap for auto-release entries. If your brokerage pipeline is set to RMD (Release on Minimum Documentation) or PARS with auto-accounting, and the surtax logic isn’t baked into the CAD template, the goods release but the full duty obligation doesn’t post to your CARM account until the next correction cycle. For importers on Release Prior to Payment (RPP) terms, that’s a bonding headache—your financial security calculation was based on estimated duties, and now the surtax lands as a surprise draw against the bond ceiling.

We’ve seen this pattern with every new duty instrument CBSA introduces. The first few months are clean-up: amended CADs, supplementary statements, and the occasional AMPS letter for importers who didn’t catch the gap. The smart move is to flag every steel derivative shipment at the pre-release stage, confirm HS classification against the updated notice, and manually verify the surtax line before the CAD transmits.

CUSMA and CETA won’t save you here

Some importers assumed that if their steel derivative goods qualify for CUSMA preferential duty treatment (HS-specific rule of origin met, CUSMA cert on file), the surtax wouldn’t apply. That assumption is wrong. The surtax order is a trade remedy measure, not an MFN tariff. It applies regardless of origin preference, unless the notice explicitly carves out a particular FTA.

The July 22 revision does clarify that goods originating under CETA (EU origin) are excluded from the surtax, provided the steel input itself is EU-originating and the regional value content threshold is met. That creates a filing decision tree: if you have a choice between a CUSMA-origin claim (which doesn’t shield you from the surtax) and a CETA-origin claim (which does), and the good qualifies under both, you file CETA. But CETA’s rules of origin for steel derivative goods are stricter—often requiring a tariff shift plus a 50% regional value content test. If you can’t prove CETA origin, you’re back to paying the surtax even if the good is CUSMA-compliant.

This is the kind of compliance work that doesn’t scale in a spreadsheet. You need someone who can read the notice, map it to your HS portfolio, cross-check your origin certs, and build the right CAD template so that every entry files correctly the first time.

What happens if you miss it

If you under-declare the surtax, CBSA’s post-release audit will assess the shortfall plus interest. Depending on how the error is categorized—mistake of fact vs. negligence—you may also face an AMPS penalty under the Regulations. The penalty grid for under-declared duties starts at $500 for a first infraction and scales with the duty shortfall and the importer’s compliance history.

The bigger operational cost is the retroactive true-up. Amended CADs have to be filed for every affected entry. If you imported steel derivative goods weekly over the past six months and your broker template was wrong the whole time, you’re looking at dozens of amendments, each one requiring a manual review, a corrected statement, and a payment to square the account. For importers managing tight cash flow or quarterly duty drawback reconciliation, that kind of surprise liability is a planning problem, not just a compliance one.

Filing it right from here

If you’re importing goods that might fall under this order, the first step is to pull the updated CN 25-33 and compare the HS scope to your commercial invoice line items. Don’t rely on your supplier’s tariff classification—verify it yourself or have your broker do a proper HS classification lookup. If the good is in scope, confirm whether you have a CETA origin option that would exempt the surtax. If not, make sure your CAD template includes the surtax line and that the rate is correct.

For goods arriving at the Port of Montreal or any sufferance facility, this also affects release timing. If the surtax wasn’t declared and the entry is flagged for examination, CBSA will hold the release pending duty correction. That can add 24 to 48 hours to your dwell time, and if you’re working against a tight dock window or a just-in-time delivery, the delay cost often exceeds the surtax itself. Our sister operation FENGYE LOGISTICS handles this every week—cargo arrives, entry is flagged, importer scrambles to file an amended CAD, and the container sits on the terminal accruing detention while everyone waits for CBSA to clear the corrected duty statement.

The fix is to get the filing right before the goods land. Pre-classify, confirm origin, template the surtax, and transmit a clean CAD at arrival. It’s not complicated work, but it requires someone who’s actually read the notice and knows how to map it to a CAD field.

If your current filing setup didn’t catch the July 17 update and you’re only hearing about the July 22 revision now, that’s a signal. Talk to us.
