Steel, Aluminum, Copper Tariff Changes and Canadian Import Classification

Key Takeaways

• Equipment containing steel, aluminum, or copper may shift HS codes depending on the predominant material classification, triggering different MFN or preferential duty rates on the CAD.
• A 15% U.S. levy embedded in the invoice price raises transaction-value questions under Customs Act section 48 when the equipment crosses into Canada for final use or further manufacture.
• CUSMA origin claims on machinery require producer affidavits tracing steel and aluminum inputs; certificates issued before the U.S. tariff effective date may need re-validation under Annex 401.
• CBSA verification requests are rising for machinery imports with mixed-metal bills of material; expect longer release windows if your CAD origin declaration conflicts with the supplier’s material-source affidavit.

U.S. tariff changes and the Canadian HS classification question

The White House announcement adjusting steel, aluminum, and copper tariffs to 15% for certain industrial and agricultural equipment creates immediate work for Canadian importers filing Commercial Accounting Declarations under CARM. The tariff change itself sits on the U.S. side of the border, but the ripple hits Canadian customs clearance in three places: HS classification, transaction-value calculation, and CUSMA origin claims.

Most industrial machinery imports under HS Chapter 84 or electrical equipment under Chapter 85. The base-metal chapters (72 for steel, 76 for aluminum, 74 for copper) apply only to semi-finished or basic shapes, not finished machinery. When equipment contains multiple materials, CBSA applies General Interpretative Rule 3(a) to classify by essential character. A steel-framed conveyor system with aluminum rollers and copper wiring still classifies as machinery, not as steel. The U.S. tariff change does not alter the Canadian HS code, but it does force importers to revisit bills of material and supplier affidavits when filing CUSMA origin claims.

The distinction matters because MFN duty rates on machinery range from free entry to 6.5%, while steel and aluminum products can attract SIMA duties if they originate in subject countries. If your supplier starts substituting steel sources to avoid the U.S. levy, the change may invalidate the CUSMA certificate you have on file.

Transaction value and embedded U.S. tariffs on the CAD

Transaction value under Customs Act section 48 is the price paid or payable for the goods when sold for export to Canada. If your U.S. supplier pays a 15% tariff and passes that cost into the invoice, the Canadian duty calculation uses the post-tariff price. CBSA does not grant a deduction for foreign taxes paid unless they meet the narrow conditions in Valuation Regulation section 5, which exclude most indirect levies.

We routinely see importers file CADs using the supplier’s quoted unit price without checking whether the quote reflects pre-tariff or post-tariff U.S. cost. The difference can shift the appraised value by double digits. If CBSA issues a valuation verification letter under Customs Act section 59, you will need a breakdown showing the U.S. tariff as a separate line or an affidavit confirming it was not included in the sale price. Missing that documentation turns into a bond-call delay while you chase paper from a supplier who has already moved on to the next order.

The safer approach: ask your U.S. vendor for two invoice lines—one for the equipment FOB, one for the U.S. tariff if separately billed—or a written statement confirming the invoice price excludes the levy. Attach the statement to the CAD in the CARM Client Portal as a supporting document. Valuation disputes that land in post-release verification can take six months to close, and the importer carries the burden of proof.

CUSMA origin claims and metal sourcing

CUSMA Annex 401 product-specific rules for machinery vary by HS heading. Many require a tariff shift (for example, a change from any heading outside Chapter 84 to heading 84.28 for industrial lifting equipment) or a regional-value-content threshold of 50% or 75%, depending on the calculation method. Steel and aluminum inputs must undergo sufficient transformation within the CUSMA territory, or they disqualify the final product.

If your U.S. supplier switches to non-CUSMA steel to sidestep the new tariff, the machinery may no longer meet the origin rule. The CUSMA certificate on file becomes invalid, and filing a preferential-treatment CAD exposes you to duty recovery and AMPS penalties during CBSA verification. Certificates issued before June 8, 2024 (the effective date in the White House notice) should be re-validated with a producer affidavit tracing the steel and aluminum back to melt or substantial transformation.

CBSA can verify any CUSMA claim within four years of the accounting date. Verification letters issued under D-memorandum D11-4-16 typically allow 30 days to respond. Common supporting documents include bills of material, supplier declarations, and production flow charts showing where each metal input enters the manufacturing process. If the producer cannot document CUSMA origin for the steel frame, the entire machine loses preferential treatment, and MFN duty applies retroactively. On a CAD 50,000 machinery import, the swing from duty-free CUSMA to 6.5% MFN is CAD 3,250 plus interest from the original accounting date.

HS classification disputes and release-prior-to-payment workflows

The new U.S. tariff structure splits equipment into rate categories based on industrial versus agricultural use. Canadian HS classification does not mirror that split, but the underlying question—what is the essential character of the equipment—remains the same. A tillage implement with a steel frame and aluminum seed hoppers classifies under HS 84.32 (agricultural machinery), not under the base-metal chapters. A steel press with copper electrical windings classifies under HS 84.62 (machine tools), not as copper wire.

When importers file a CAD with the wrong HS 6-digit code, the CARM Client Portal flags tariff-treatment mismatches before calculating the RPP bond estimate. If you claim CUSMA duty-free treatment but the HS code you entered does not support the claim, the release stalls until you either correct the HS code or withdraw the origin declaration. Under CARM Phase 2 Release 3, live since October 2024, the financial-security requirement ties directly to the declared HS code and tariff treatment. Classification errors cost time at release and create post-release verification risk.

For mixed-metal equipment, request an advance ruling through the CBSA advance rulings program before the first shipment. Turnaround time is approximately 120 days, and the ruling binds CBSA for future entries of identical goods. If you need a faster answer, our HS classification service provides broker opinions with supporting General Interpretative Rule citations and Explanatory Note references within three business days. Broker opinions are not binding, but they establish due diligence if CBSA later challenges the code.

Warehouse staging and documentation before release

Equipment shipments flagged for CBSA examination or origin verification sit in a bonded facility until the hold clears. If your machinery arrives in Montreal and the CAD is under review for a CUSMA claim tied to questionable steel sourcing, dwell time stretches from same-day release to four or five working days. The equipment cannot move to your production floor or job site until CBSA closes the verification query.

FENGYE LOGISTICS operates a bonded and sufferance facility adjacent to the Port of Montreal container terminals, providing short-term staging for shipments awaiting customs clearance. When a CAD is on hold for document review, cargo stays bonded at daily storage rates rather than incurring terminal demurrage. Once the clearance closes, cross-dock or direct delivery moves the equipment the same day.

For importers managing multiple machinery entries each month, clean documentation before the arrival—HS classification confirmation, CUSMA certificates with producer affidavits, transaction-value breakdowns—cuts release windows from days to hours. CBSA’s release-prior-to-payment process under CARM depends on accurate CAD data up front. Errors discovered post-release trigger B2 adjustments, potential AMPS contraventions, and bond calls if the correction increases the duty owed.

What to do before the next machinery shipment

Pull the CUSMA certificates for any U.S. machinery suppliers whose goods contain steel, aluminum, or copper. Confirm the producer affidavit traces the metal inputs to CUSMA-origin mills or documents the tariff-shift transformation. If the supplier switched sources after June 8, 2024, request an updated certificate before filing the next CAD.

Review your last three CADs for machinery imports. Check that the declared transaction value matches the invoice line and that no U.S. tariff was embedded without disclosure. If the value looks understated or the supplier’s quote structure changed recently, ask for a written breakdown before CBSA does.

Run the HS 6-digit code for each machine type through the Canadian Customs Tariff to verify the tariff treatment you claimed. If you have been using a broker opinion or an old ruling, confirm it still applies to the current product configuration. Material substitutions, even minor ones, can shift the HS code under General Interpretative Rule 3.

Most classification and origin disputes start with incomplete documentation at filing. We see it weekly: a CAD goes in with a valid CUSMA certificate, but the certificate does not match the HS code on the entry, or the producer affidavit omits the steel supplier’s location. CBSA flags it, the shipment sits in bond, and the importer scrambles for paper that should have been attached to the CAD in the first place.

If you are filing CADs for equipment with mixed-metal content and the U.S. tariff changes have you second-guessing origin or valuation, get in touch. We file CADs against these fact patterns every day.

Frequently Asked Questions

What HS chapter covers industrial machinery that contains steel and aluminum components?

Most industrial machinery falls into HS Chapter 84 (machinery and mechanical appliances) or Chapter 85 (electrical machinery), not the base-metal chapters (72–76 or 74 for copper). CBSA applies General Interpretative Rule 1 and Rule 3(a) to classify by essential character. Classification decisions are binding under Customs Act section 60, and advance rulings take approximately 120 days.

Does a U.S. tariff paid by my American supplier affect the transaction value I declare on the Canadian CAD?

Transaction value under Customs Act section 48 includes the price paid or payable for the goods. If your invoice line reflects the post-tariff U.S. sale price, that number becomes the basis for Canadian duty calculation. Verify with your supplier whether the U.S. levy is separately invoiced or rolled into the unit price; CBSA may request a breakdown during post-release verification.

Can I still claim CUSMA preferential duty on machinery imported from the U.S. if it contains foreign-origin steel?

CUSMA Annex 401 product-specific rules for machinery (HS 84 and 85) vary by heading. Many require a tariff shift from outside Chapter 84/85 or a regional-value-content threshold of 50–75%. If the steel originated in a non-CUSMA country and does not undergo the required transformation, the machinery may fail origin. Request a CUSMA certificate of origin and producer affidavit before filing the CAD.

What triggers a CBSA origin verification after I file a CUSMA claim on my CAD?

CBSA can verify any CUSMA claim within four years of the accounting date. Common triggers include mismatched HS codes between the certificate and the CAD, producer addresses outside the CUSMA territory, or prior verification flags on the same supplier. Verification letters issued under CBSA memorandum D11-4-16 typically allow 30 days to respond with bills of material and production records.

If the U.S. lowers the tariff to 15% on certain equipment, does that change my Canadian duty rate?

No. Canadian import duty is determined by the goods’ HS classification, country of origin, and the applicable tariff treatment (MFN, CUSMA, CETA) in the Canadian Customs Tariff. U.S. domestic tariffs do not alter Canadian rates, but they may inflate the transaction value you declare on the CAD if the U.S. levy is embedded in your purchase price.

How does CARM Phase 2 Release 3 affect how I file CADs for machinery with mixed-metal components?

CARM Phase 2 Release 3, live since October 2024, requires importers to post financial security and file CADs through the CARM Client Portal. The filing process itself is unchanged, but HS classification errors now appear faster in the release-prior-to-payment workflow because the portal cross-checks your declared HS code against tariff-treatment eligibility before calculating the RPP bond estimate.

What happens if I discover my CAD used the wrong HS code for a machine that turned out to be mostly aluminum?

You have 90 days from the accounting date to file a B2 adjustment under Customs Act section 32.2. If CBSA discovers the error first during post-release verification, you may face an AMPS contravention under infringement code C051 (incorrect tariff classification). Voluntary corrections submitted with full supporting documentation typically avoid penalty assessment.

Where can I get technical HS classification support for equipment with embedded steel, aluminum, or copper?

CBSA publishes classification opinions and National Customs Ruling (NCR) letters. For complex machinery, request an advance ruling through the CBSA advance rulings program or work with a licensed customs broker who holds Customs Tariff access and can cite General Interpretative Rules and Explanatory Notes. Turnaround time is approximately 120 days for formal rulings.
