U.S. Steel Tariffs and What They Mean for Canadian Importers Filing CADs

Key Takeaways

• U.S. steel production is growing faster than imports decline, and Canadian buyers sourcing American product will file more CUSMA origin claims on CADs this year.
• SIMA applies to steel imports from specific countries under D14-1-3; switching suppliers mid-contract can trigger anti-dumping margin liability if you miss the exclusion list.
• HS classification for coated versus uncoated steel sits in Chapter 72, and getting it wrong costs time at CBSA verification or an AMPS contravention later.
• If your U.S. steel shipments cross via PARS and you hold an RPP bond, confirm the bond ceiling covers your new monthly duty exposure before volumes climb.

U.S. Steel Production Climbs While Imports Drop

U.S. steel imports fell 30 percent in 2026 compared to the prior year, driven by higher domestic tariffs and expanded onshore production capacity. April 2026 census data showed raw and finished steel volumes reached 1.87 million net tons for the month, with tin plate, metallic coatings, and other finished products still crossing borders in significant volume. For Canadian importers who source steel products, the shift matters because your supplier base is moving south and your CAD filings will reflect new origin claims, different HS classifications, and fewer SIMA complications.

When U.S. mills add capacity and tariffs make offshore product uncompetitive, American steel becomes the default choice for buyers in Ontario and Quebec. That means more CUSMA origin certifications, more highway PARS shipments crossing at Windsor and Lacolle, and more questions about whether your release-prior-to-payment bond can handle the monthly duty exposure when volumes climb.

CUSMA Origin and What It Means for Your CAD

Steel products imported from the United States may qualify for CUSMA preferential tariff treatment under Chapter 4 Annex 4-B rules of origin. The product-specific rule typically requires a tariff-shift test or substantial transformation, and your U.S. supplier must provide a completed CUSMA certification or you must hold sufficient production records to self-certify. You claim the preference on your Commercial Accounting Declaration at the time of release through the CARM Client Portal. Retroactive claims are possible under Customs Act subsection 32(2), but filing the claim upfront is cleaner.

If you get the origin claim wrong, CBSA can verify your certification under CUSMA Article 5.9 up to five years after import and recover any unpaid duty. We see verification requests most often when importers switch suppliers mid-contract and fail to update the certification paperwork. The penalty is not just the duty shortfall; AMPS can assess an administrative monetary penalty if CBSA determines the claim was negligent.

SIMA Still Applies to Some Steel, But Not U.S. Product

SIMA (Special Import Measures Act) imposes anti-dumping and countervailing duties on subject goods from listed countries. Steel products from China, India, South Korea, and other origins named in the CBSA SIMA registry carry AD and CVD margins that can reach double digits. U.S. steel is not currently subject to SIMA measures, so switching from offshore to American product eliminates the margin liability.

Before you file your CAD, confirm the country of origin and check the CBSA SIMA registry to see whether your product and origin combination is subject. If it is, you will pay the normal-value margin or the export-subsidy margin on top of the MFN duty rate. If you import subject goods and fail to declare them correctly, CBSA will adjust the entry during verification and assess the shortfall under D14-1-3 guidelines. That adjustment can take months to surface, and the interest clock starts from the original release date.

HS Classification for Coated and Uncoated Steel

Most raw and semi-finished steel classifies under HS Chapter 72, with flat-rolled products occupying headings 7208 through 7212 and bars, rods, and structural shapes sitting at 7213 through 7216. The distinction between hot-rolled and cold-rolled product matters because the tariff rate and CUSMA rule of origin differ by heading. Hot-rolled flat products classify under HS 7208 (non-alloy) or 7225 (alloy), while cold-rolled products move to 7209 or 7226.

Coated steel (galvanized, painted, or otherwise surface-treated) typically falls into HS 7210 or 7212, depending on the base metal and coating type. Misclassifying coated versus uncoated product can shift the MFN duty rate by several percentage points, and CBSA may flag the entry for HS verification if the declared code does not match the commercial invoice description. If you are unsure, run the product through our HS classification tool or ask your supplier for a technical specification sheet before you file the CAD.

RPP Bond Sizing When Volumes Climb

If you hold a release-prior-to-payment bond and your U.S. steel volumes double mid-quarter, your bond ceiling may no longer cover the estimated monthly duty and GST exposure. CBSA requires continuous bonds to equal or exceed the highest month’s liability, and if you breach that ceiling, the agency can suspend release privileges until you post additional financial security.

We routinely see importers hit the bond limit when they consolidate offshore orders into fewer U.S. suppliers or when tariffs push them to reshore sourcing faster than their compliance team updates the bond paperwork. Review your K84 monthly statement every cycle, and notify your surety before you cross the threshold. Posting a new bond or increasing the existing one takes time, and your shipments will sit at the border if CBSA flags the account for insufficient security.

Physical Clearance: PARS Versus Marine RMD

U.S. steel crossing via highway typically moves under PARS (Pre-Arrival Review System) with FAST clearance, and release often occurs within hours if the CAD is clean and your RPP bond is active. Offshore containers arrive by ocean, clear under marine release-on-minimum-documentation procedures, and may sit longer if CBSA flags the shipment for SIMA verification or HS audit.

The physical timeline is shorter when you source from the United States, but the compliance workload shifts to origin certification and HS accuracy. If your inbound drayage delivers to a Montreal sufferance warehouse for cross-dock or order consolidation, confirm the clearance is complete before the truck arrives. Sufferance operators cannot release goods until CBSA transmits the release notice, and detention charges accumulate quickly if the shipment sits on the dock waiting for paperwork.

What to Watch When U.S. Tariffs Push Production Onshore

Tariff-driven reshoring is not new, but the speed of the shift in 2026 caught many importers without updated CUSMA certifications or bond coverage. If your steel supplier base is moving to the United States, review these items before your next shipment crosses:

• CUSMA certification: Does your U.S. mill provide a completed certification, or do you need to self-certify origin? File the claim on your CAD at release, not later.
• HS classification: Confirm the six-digit code for coated versus uncoated product, and verify the tariff rate matches your invoice.
• RPP bond ceiling: Check your K84 statement and notify your surety if monthly duty exposure is climbing.
• SIMA exclusion: U.S. steel is not subject to SIMA, but if you still source offshore product from listed countries, declare the AD/CVD margins correctly on your CAD.
• PARS versus marine: Highway clearance is faster, but only if your broker files the CAD before the truck reaches the border and your eManifest cargo control number is clean.

If you handle freight forwarding in-house, coordinate the carrier manifest with your broker so the CAD and cargo control number align. If CBSA cannot match the two records, the shipment will not release until the discrepancy is resolved.

How This Plays Out on Your Next CAD

When you file a CAD for U.S. steel, the CARM Client Portal will prompt you to declare origin, HS code, duty rate, and any preferential claims. If you claim CUSMA, attach the certification reference or upload the document if CBSA requests it during verification. If you import subject goods from another country, declare the SIMA margin and pay it at release or under your RPP bond terms.

We file dozens of CADs every week for steel importers who switched suppliers in the past year. The most common errors are missing CUSMA certifications, incorrect HS codes for coated product, and bond ceilings that no longer cover monthly exposure. All three are fixable before the shipment crosses, but fixing them after CBSA flags the entry costs time and often triggers an AMPS review.

If your U.S. steel volumes are climbing and you need someone to review your origin documentation or bond sizing, get in touch. We run the math on bond exposure and HS classification every day.

Frequently Asked Questions

Does SIMA apply to steel I import from the United States?

SIMA (Special Import Measures Act) applies only to subject goods from listed countries, per CBSA’s D14-1-3 memorandum. U.S. steel is not currently subject to SIMA anti-dumping or countervailing duties, so you will not pay AD or CVD margins on American product. If you source from China, India, or other named origins, check the CBSA SIMA registry before filing your CAD.

What HS codes cover raw and finished steel for CAD filing?

Most raw and semi-finished steel falls under HS Chapter 72. Flat-rolled products (hot-rolled, cold-rolled, coated) typically sit at 7208–7212, while bars and structural shapes occupy 7213–7216. Finished articles made of steel (pipes, wire, fasteners) move into Chapters 73 and beyond. Misclassifying coated versus uncoated product can shift the MFN duty rate by several percentage points, so confirm the six-digit HS before you file.

How do I claim CUSMA origin preference on U.S. steel shipments?

Steel must meet CUSMA Chapter 4 Annex 4-B product-specific rules of origin, which require substantial transformation or a tariff-shift test. You need either a completed CUSMA certification from your U.S. supplier or sufficient production records to self-certify origin. File the preference claim on your CAD through the CARM Client Portal at the time of release; retroactive claims are harder. CBSA can verify origin under CUSMA Article 5.9 up to five years after import.

What happens to my RPP bond if U.S. steel volumes double this quarter?

Your release-prior-to-payment bond must cover estimated monthly duty and GST exposure. If volumes climb and you cross the bond ceiling, CBSA can suspend release privileges until you post additional financial security. We routinely see importers hit that ceiling mid-quarter when they switch suppliers or consolidate orders. Review your K84 monthly statement and notify your surety before you breach the limit.

Can I use the same HS code for hot-rolled and cold-rolled steel?

No. Hot-rolled flat products classify under HS 7208 (non-alloy) or 7225 (alloy), while cold-rolled products move to 7209 or 7226. The distinction matters because tariff rates and CUSMA rules of origin differ by heading. If you file the wrong code on your CAD, CBSA may adjust it during verification and assess any shortfall under AMPS.

Does switching from offshore to U.S. steel change my CBSA clearance timeline?

U.S. steel crossing via highway typically moves under PARS (Pre-Arrival Review System) with FAST clearance, and release often occurs within hours if the CAD is clean and your RPP bond is active. Offshore containers arrive by ocean, clear under marine RMD, and may sit longer if CBSA flags the shipment for SIMA verification or HS audit. The physical timeline is shorter; the compliance workload shifts to origin certification.

What CBSA documentation do I need when I import U.S. steel for the first time?

You need a commercial invoice, CUSMA certification (if claiming preference), packing list, and carrier manifest. If the product is alloy steel, confirm whether it requires a mill test certificate for CFIA or technical standard compliance. Your broker files the CAD through the CARM Client Portal, referencing the cargo control number from the carrier’s eManifest. First-time importers should also confirm their CARM portal enrolment and RPP bond are active before the truck reaches the border.
