CBSA Final Determination on Chinese UBC Imports: One Exporter Out, Subsidy Duties Lock In for the Rest

On October 27, 2026, CBSA closed the subsidy investigation on unarmoured building cables from China with a split decision: one exporter (Tianjin Feiya Fengda Wire & Cable Technology Co., Ltd.) walks away clean under SIMA paragraph 41(1)(a), and everyone else gets hit with final subsidy duties under 41(1)(b). If you’re bringing UBC in from China and your supplier isn’t Tianjin Feiya Fengda, your landed cost just went up and your CAD filing process now includes a SIMA line every time.

What’s Caught

Unarmoured building cables are multi-conductor insulated wire assemblies typically classified under HS 8544.49 or 8544.42, depending on rated voltage and end-use. The CBSA investigation scope covers cables used in residential, commercial and industrial electrical installations, usually PVC or XLPE insulated, without metallic armour. If your product has steel tape wrap or interlocked armour, it’s out of scope. If it’s bare conductor or single-conductor wire, it’s out. The scope description in the CBSA SIMA notice will be the gatekeeper for every Customs ruling and tariff classification dispute from here on, so if you’re on the edge of the product definition, get a ruling now before you file another CAD.

Most importers in this category have been living under provisional duties since the preliminary determination earlier this year. The final determination converts those provisional amounts into permanent subsidy duty rates, and the Canadian International Trade Tribunal (CITT) will issue an injury finding shortly (assuming they follow the usual SIMA timeline). Once the CITT finding lands, the combined anti-dumping and countervailing duty regime is locked in for five years unless a review changes it.

One Exporter Terminated, the Rest Pay

The termination for Tianjin Feiya Fengda is narrow. CBSA terminated the subsidy investigation for that one exporter, meaning UBC from that specific company will not attract subsidy duties. Anti-dumping duties may still apply if dumping was found (the notice excerpt doesn’t specify whether dumping was also terminated for this exporter, and the two investigations run in parallel). Every other Chinese exporter of UBC gets the final subsidy determination, which means a permanent countervailing duty rate appears on their goods.

If you import from Tianjin Feiya Fengda, your CAD will still require the SIMA case number and exporter code, but the subsidy duty line should assess at zero. If you import from anyone else in China, expect a positive CVD rate. The actual rates by exporter will be published in the final determination documents on the CBSA SIMA registry. Cooperative exporters who participated in the investigation get their own calculated rate. Non-cooperative exporters and all others get the residual rate, which is typically the highest margin found during the investigation.

This is the part that catches importers off guard: if your Chinese supplier didn’t participate in the CBSA investigation and submit full cost and subsidy questionnaires, you’re stuck with the residual CVD rate even if your supplier received zero subsidies. The burden was on the exporter to engage during the investigation period. If they didn’t, the penalty is the residual rate for the next five years.

What Changes on the CAD

Every CAD for subject goods now requires the SIMA case code (UBC 2026 IN), the exporter name exactly as it appears in CBSA records, and the applicable subsidy duty rate. Value for duty is still transaction value under Customs Act section 48, adjusted to FOB or FCA terms if freight and insurance are documented separately. The subsidy duty is calculated on that same value for duty base, then added to the duty line. Import GST at 5% applies to the sum of value for duty, customs duty, and subsidy duty under Excise Tax Act section 215.

If you’ve been releasing shipments under Release Prior to Payment (RPP) with a bond, the subsidy duty amount now factors into your monthly Statement of Account balance and your bond sufficiency calculation. CBSA reviews RPP bonds periodically, and a jump in SIMA duty exposure can trigger a bond increase request. If your UBC volume is significant and you’re suddenly carrying a 20% or 30% CVD margin, your bond may no longer cover thirty days of duty and tax liability. That’s a compliance conversation to have now, not after CBSA suspends your release privileges.

Retroactive Assessments and Provisional Duty Refunds

If provisional duties were in place, CBSA will reconcile the provisional amounts paid against the final duty rates. Importers who paid provisional duties higher than the final rate get a refund. Importers who paid lower provisional duties (or whose exporter’s rate went up between preliminary and final) owe the difference. The reconciliation happens automatically through the CARM Statement of Account, but it’s worth reviewing the math. If the assessed amount looks wrong, you have ninety days from the re-determination notice to file a section 60 appeal to the CBSA President, and another ninety days after that to appeal to the CITT if the CBSA review doesn’t go your way.

Shipments that arrived before the preliminary determination and released without provisional SIMA duties are usually safe (the effective date of provisional duties is the preliminary determination date). Shipments that arrive after the final determination date are subject to final duties immediately. Shipments in transit on the final determination date follow the usual rule: liability is determined by the date the goods are released, not the date they shipped or the date of the commercial invoice.

What Importers Should Do Right Now

Pull your supplier list and confirm which Chinese exporter name appears on your commercial invoices and packing lists. Cross-check that name against the CBSA termination notice and the final determination exporter table. If you’re importing from Tianjin Feiya Fengda, make sure your broker has the termination documentation on file and is coding the CAD correctly to claim the zero subsidy rate. If you’re importing from any other Chinese supplier, find out whether they were a cooperative exporter with a calculated rate or whether you’re stuck with the residual.

If the residual rate is painful and your supplier didn’t participate in the original investigation, it’s too late to fix that. The next opportunity is a SIMA review, which can happen at the exporter’s request or at certain intervals set out in SIMA. In the meantime, consider whether non-subject sources (other countries, or domestic Canadian supply) are viable. CUSMA, CETA and CPTPP all offer duty-free treatment for originating goods, and while building cables from Mexico or the EU may not be common, the tariff elimination schedules under those agreements cover HS 8544. Run the HS classification and origin analysis before you assume the trade agreement won’t help.

If your inbound UBC volume moves through our Montreal sufferance facility, we can hold and release under PARS with the SIMA coding sorted before the goods leave the dock. CBSA examinations on subject goods are more common during the first six months after a final determination, and an exam that finds misclassified or mis-declared UBC will generate an AMPS penalty on top of the duty shortfall. Get the CAD right the first time.

Most SIMA cases are boring five-year grinds once the final determination is published. This one is no different. If you import UBC from China, the new duty rate is now part of your cost structure until 2031 unless a review changes it. Budget for it, update your duty drawback claims if you’re re-exporting finished goods, and make sure your broker knows which exporter you’re actually buying from. The termination for Tianjin Feiya Fengda is the only free pass in the case, and it only works if the name on your paperwork matches exactly.

We file CADs against SIMA determinations every day. If your supplier is on the residual rate and you want to know whether a new source or a tariff engineering fix makes sense, get in touch.
