CUSMA Stays, Renews Annually Starting July 2026 — What Changes for Your Preference Claims

On July 1, 2026, the US formally declined to renew CUSMA during the agreement’s first mandatory joint review. Mexico and Canada had already signaled they wanted to renew. The US said no.

This doesn’t kill the agreement. CUSMA stays in force. But instead of locking in another term, the three countries now enter an annual review cycle. Every year from now until the scheduled 2036 expiration, the parties meet and decide whether to extend. Any one of them can pull the plug with six months’ notice.

For Canadian importers filing CUSMA preference claims, that annual uncertainty is the new cost.

What Annual Review Means for Preference Claims

A CUSMA preference claim on your CAD filing saves you the MFN duty rate. If you’re bringing in automotive parts, textiles, steel, or anything else with a meaningful tariff, that claim is worth money. The problem is CUSMA preference claims are verified retroactively. CBSA can audit origin documentation three years back.

If CUSMA terminates mid-cycle — say, the US declines to extend in July 2027 and the six-month notice period runs — what happens to the preference claims you filed in early 2027? You were compliant when you filed. The agreement was in force. But if CBSA comes back two years later during a verification and CUSMA is gone, does the claim hold?

The agreement says it does. Article 34.6 protects goods entered while CUSMA was in force. But the audit and penalty risk sits with you, the importer of record. If CBSA’s systems flag your claim during a post-termination verification, you’re the one explaining why it should still clear.

We’ve seen this movie before. When NAFTA rolled into CUSMA in 2020, claims filed under NAFTA in the transition window got extra scrutiny. The legal answer was clear. The operational answer was: budget for more verification requests and longer CBSA turnaround.

Origin Documentation Strategy Under Annual Uncertainty

If you’re filing CUSMA preference claims today, tighten your documentation. The annual review cycle means every July is a potential decision point. CBSA doesn’t care that the US political calendar is messy. If they verify your claim and your supplier’s origin affidavit is sloppy, you pay the difference plus interest.

Get supplier affidavits in writing, signed, with HS classification and regional value content calculation. Not an email. A real document. If you’re claiming based on tariff shift, document the non-originating inputs and the shift that occurred. CBSA wants to see the work. Keep three years of backup. The agreement says CBSA can verify that far back. Assume they will.

This isn’t new advice. It’s just higher stakes now. Under a stable agreement, sloppy documentation might get you a warning. Under an annual-review agreement where termination is a calendar event, sloppy documentation gets you reassessed.

Duty Planning and Long-Term Sourcing

If you’re sourcing from the US or Mexico under a CUSMA preference and your product has a 5% to 8% MFN duty rate, the annual review cycle is a cost planning problem. You can’t assume duty-free access for the next ten years. You can plan for it each year, with a six-month termination window.

For capital goods, automotive, or anything with long procurement cycles, that’s a real constraint. If you’re committing to a three-year supply contract with a US manufacturer, price in the risk that CUSMA preferences disappear halfway through. Either build a clawback into the contract or plan for MFN duty exposure as the base case.

Some importers are already doing this. We’re seeing more clients ask us to model both scenarios: CUSMA stays, CUSMA goes. The delta is their risk premium. If it’s small, they price it in. If it’s large, they renegotiate or reshore.

What CBSA Has Said (and Hasn’t)

CBSA hasn’t issued specific guidance on how annual review affects preference claim processing. The CBSA website still treats CUSMA as in force, which it is. The D-memos on origin haven’t changed. The CARM portal still accepts CUSMA claims on the CAD without flagging them for extra review.

That silence is typical. CBSA won’t preemptively revise guidance for a hypothetical termination. They’ll wait until one of the parties actually triggers the six-month notice, then issue a CBSA Customs Notice with filing instructions. By that point, you’ve got six months to adjust your supply chain.

If you’re waiting for CBSA to tell you what to do before the notice period starts, you’re waiting too long. The move is to stress-test your sourcing and duty exposure now, while CUSMA is still stable.

Cross-Border Drayage and Warehousing Implications

If you’re running cross-border freight, the annual review cycle doesn’t change your immediate release procedures. PARS, ACI, and eManifest all work the same. CUSMA preferences on the CAD are still processed at release. The difference is the downstream verification risk.

For importers using Canadian sufferance warehousing to defer duty payment on US-origin goods, the math gets interesting. If you’re holding inventory in a sufferance warehouse under a CUSMA preference claim and the agreement terminates during your storage period, you’ll owe MFN duty when you pull the goods for domestic consumption. The preference claim was valid at import, but the consumption entry happens post-termination.

We work with FENGYE LOGISTICS on the physical side for clients running that playbook. Their advice mirrors ours: if you’re deferring duty on a CUSMA claim, plan for both outcomes. Don’t assume the agreement stays intact for your entire storage cycle.

What You Should Do Now

Audit your CUSMA preference claims. Make sure your origin documentation is complete and defensible. If CBSA verifies you in 2027 or 2028, you want the answer ready.

Model your duty exposure under both scenarios. Know what it costs if CUSMA terminates. If the delta is material, hedge it in your sourcing contracts or your duty planning.

Watch the annual review calendar. The next meeting is July 2027. If one of the parties signals intent to terminate, you’ll have six months to adjust. That’s not a lot of time if you’re running lean procurement.

CUSMA is still in force. Preference claims still work. But the annual review cycle makes the agreement less of a given and more of a rolling one-year commitment. For Canadian importers, that’s a shift from “plan for ten years” to “plan for this year, and the next.”

If your CUSMA preference claims are a meaningful part of your duty exposure, that’s the kind of scenario planning we run all day. Get in touch.
