The Name Change Itself Is Cosmetic
CBSA announced April 16 that the SIMA Registry and Disclosure Unit is now called the Registry for Trade Remedies. The old email — simaregistry-depotlmsi@cbsa-asfc.gc.ca — is dead. Use trade_remedies_registry-registre_recours_commerciaux@cbsa-asfc.gc.ca going forward.
If you're importing subject goods, update your internal procedures, your broker's instructions, and any distribution lists where you stored the old contact. That's the housekeeping. But the real issue isn't the rebrand — it's whether your SIMA compliance posture is actually solid, because this is a high-stakes corner of the Customs Act where you don't get do-overs.
What SIMA Compliance Actually Requires
When goods are subject to anti-dumping or countervailing duties under SIMA, you're not just paying normal customs duties. You're paying a variable margin that can be enormous — sometimes doubling or tripling landed cost — and that margin is tied to the producer, the exporter, and sometimes the transaction type. The B3 filing has to be accurate at line-item level: correct HS classification, correct country of origin, correct Normal Value if applicable, and often a specific SIMA code or narrative in the remarks field.
Miss any of those, and you've filed a deficient B3. CBSA can reassess within four years. If you underpaid SIMA duties, you owe the shortfall plus interest, and there's no relief provision like there is for origin preferential claims. You can't fix it with a post-release amendment and call it a day — you're looking at a full compliance review, possibly a verification, and if it's systemic, a multi-year lookback.
This is why the Registry contact matters. If you need to file a Request for Re-determination under subsection 60(1) of SIMA, or if you're responding to a verification letter, or if you're trying to get an advance ruling on whether a slightly modified product is still subject goods, you're dealing with this unit. They're not the Trade Programs Directorate (policy side) and they're not your local CBSA office. They're the operational registry, and their timelines are strict.
Where Importers Screw This Up
The most common mistake is treating SIMA like a static problem. You imported subject goods two years ago, paid the duty, moved on. But SIMA measures get updated. Interim reviews happen. Expiry reviews extend measures. New Normal Values get published. The China-specific measures on steel pipe, for example, have been amended half a dozen times in the last five years, and the applicable margin depends on which producer made your goods and when you imported them.
If your broker is working off stale instructions, or if you're self-filing in CARM and copy-pasting old B3 data, you're at risk. The second common failure is HS classification drift. A product that was clearly subject goods under 7306.30.00.10 gets tweaked by your supplier — wall thickness changes, alloy composition shifts — and now it's arguably 7306.30.00.90, which may or may not be subject. You file it the old way because that's what's in your ERP. CBSA catches it on a random audit. Now you're explaining why you didn't seek a ruling.
The third one is NRI penalties. If you're a non-resident importer bringing in subject goods and your Canadian agent isn't up to speed on SIMA filing requirements, you're both exposed. The NRI is jointly and severally liable for duties, and CBSA doesn't care whose fault it was. The agent's bond gets hit, the NRI gets a collections notice, and the relationship sours fast.
What to Do With the New Contact
If you're importing subject goods right now, send a test email to the new address with a simple query — confirm your importer number is on file, confirm the applicable Normal Value for your last shipment, whatever. Just verify the mailbox works and you get a human response. Build that into your onboarding for any new SIMA-affected product line.
If you're in the middle of a re-determination or a verification, forward any outstanding correspondence to the new address and reference your old case number. Don't assume it's been migrated automatically. CBSA's inter-unit handoffs are not always seamless, and you don't want your reply lost in a dead mailbox.
If you're not sure whether your goods are subject, use this as a nudge to request a formal ruling. The Registry for Trade Remedies doesn't issue HS rulings — that's still the National Customs Ruling Program — but they can confirm whether a specific HS code and origin combination is on the current SIMA measures list. Get it in writing. An email from a broker saying "we think you're clear" is not a defence if CBSA disagrees.
CARM Adds a Layer of Risk
Under CARM, importers of record are now financially liable at time of release if they're using release prior to payment. If you're bringing in subject goods and your estimated SIMA duty is wrong, your RPP bond gets dinged for the shortfall. If your bond ceiling is too tight, CBSA can suspend your account and hold all shipments until you top up or switch to payment-on-release.
Most importers sized their RPP bonds based on average duty rates pre-CARM. If you've added a new product line subject to anti-dumping duties, and you didn't recalculate your bond, you're flying close. SIMA duties are variable, so your bond exposure is variable. A single high-value shipment with a 200% margin can blow through your cushion.
This is also where customs compliance audits become existential. CBSA is already running CARM-linked compliance verifications. If they find SIMA misclassification or underpayment, they're not just sending a letter — they're adjusting your financial security requirements in real time. Your next shipment might get held because your bond math no longer works.
Bottom Line
The Registry name change is a detail. The operational reality is that SIMA is one of the few areas in Canadian customs where the penalty for getting it wrong is severe, immediate, and hard to reverse. If you're importing subject goods, your B3 data hygiene has to be perfect. Your broker instructions have to be current. Your HS classification has to be defensible. And your duty management strategy has to account for variable margins and bond exposure.
If you've been treating SIMA like a set-it-and-forget-it compliance checkbox, use this notice as a prompt to revisit your process. Pull the last six months of B3s for any subject goods, confirm the Normal Values match what's published, and make sure your bond math still holds. If you're not confident, that's a problem worth fixing before CBSA finds it for you.
If you're sitting on a product line where SIMA applicability is ambiguous, or if your bond exposure has crept up and you're not sure how to model it, get in touch. These are the calls we handle every week.
