The White House Document Reaches the Dock
When the US Customs authority issues a formal warning about transshipment evasion, CBSA listens. Containers flagged for origin and tariff misclassification get held. Exam queues grow. Drayage windows shrink. Your importer's cross-dock cutoff slips into next week.
The White House identified three tactics that US Customs sees repeatedly: re-invoicing goods to claim a lower-tariff intermediate country as origin, repackaging and relabeling to obscure the actual source, and claiming minimal processing in a transshipment hub qualifies goods as originating there under trade cumulation rules. None of this is secret. But when the White House codifies it as policy and US CBP tightens enforcement, CBSA coordinates. Expect more exams.
Two Types of Transshipment
Importers and forwarders using transshipment routing fall into two categories: legitimate supply chain optimization and tariff-dodge risk.
Legitimate transshipment is routine. You have suppliers in different regions and consolidate inbound via a hub in a third country. Paperwork is clean. Invoices match bills of lading. Origin is accurately marked. Goods either pass through without modification or are substantially transformed in the intermediate jurisdiction. Those containers clear in 48 hours.
Tariff-dodge transshipment is different. Goods are routed via lower-tariff jurisdictions specifically to misrepresent origin and evade duties. Re-invoicing is sloppy. Packaging doesn't match invoices. Country-of-origin markings conflict with bills of lading. When CBSA sees that pattern, the container goes into exam queue.
The Hold Cascade at the Warehouse
At FENGYE LOGISTICS, we coordinate with brokers on inbound all day. The cost of an exam hold isn't just two to three days sitting at the warehouse. It's the cascade that follows.
Drayage slot gets handed to the next shipment. Your importer's cross-dock cutoff—ours is 14:00 EDT for next-day Ontario/Quebec pickup—gets missed. The container sits overnight at our in-bond holding rate: $40 per skid for handling and storage, plus $12 per skid in/out fees. For a 20-pallet LTL, that's $1,040 per day. A three-day hold costs $3,120 plus drayage remobilization fees to reschedule the carrier.
We routinely see exam flags on 15 to 22 percent of containers with intermediate-jurisdiction routing on our dock. Post-White House warning, expect those rates to climb. CBSA will prioritize origin verification exams for several months as enforcement signals harden.
CBSA's Legal Grip
Under the Customs Act, CBSA has broad discretion to verify country of origin. If CBSA suspects goods are mislabeled as to origin to evade tariffs or are subject to trade remedy provisions, they hold the container and request supporting documentation from the importer or broker.
The onus is on the importer to prove origin, not on CBSA to disprove it.
A broker filing a CAD (Commercial Accounting Declaration) per CBSA guidelines for transshipment cargo should be upfront about origin and provide clean packing lists, invoices, and country-of-origin markings that align. Any mismatch and the hold starts.
What Importers Need to Do Now
Audit your transshipment routings this week. For each transshipment pattern you use, check three things:
HS classification and tariff rate. Does the tariff savings justify the intermediate routing, or are you just trying to evade duties. If it's the latter, recalculate total cost: tariff savings minus exam hold costs minus drayage remobilization. The spread may vanish.
Origin marking. Goods must be clearly and indelibly marked as to country of origin per CBSA rules. If goods are repackaged or relabeled during transshipment, the new marking must still be accurate. Scraping, obscuring, or falsifying country-of-origin markings is a red flag CBSA catches in two minutes.
Invoice and bill of lading alignment. They must match. If the invoice says origin is Country B but the bill of lading shows shipment from Country A via Country B, you're inviting an exam. If they conflict, the hold extends to 5+ days while CBSA digs for supporting evidence.
If documentation is clean, an exam is routine and clears in 48 hours. If there's ambiguity or mismatch, plan for a five-day hold.
The Math Breaks for Tariff Arbitrage
Here's where this gets real. Suppose an importer was routing goods via Country B to save CAD 5,000 in tariffs compared to direct inbound. The transshipment service cost CAD 800. Net savings: CAD 4,200.
Now add the exam hold scenario: two to three days holding at FENGYE (CAD 1,000 to 1,500), drayage remobilization (CAD 800 to 1,200), and tariff re-assessment risk if CBSA re-classifies goods and you owe back duties plus penalty interest.
The spread collapses. Direct inbound, even at 10 to 15 percent higher freight cost, becomes attractive if it avoids exams and tariff disputes. We're seeing this shift already. Importers are asking about direct inbound from EU, even at higher cost. That's rational. The tariff-dodge math doesn't work anymore.
What Smart Brokers Are Doing
Smart brokers flag transshipment patterns upfront. When they see routing that could look risky—re-invoicing, unclear origin, minimal processing—they request clean docs from the importer before filing the CAD. This front-loads the work and avoids exam queue delays.
Brokers should also flag to clients that US tariff enforcement is tightening. If a client's transshipment routing was built on savings that no longer pencil out post-hold, the broker recommends direct inbound or a different supply chain strategy. That's value-added compliance work.
Container Free Time and Holding Costs
Port of Montreal offers five calendar days container free time before demurrage charges start. In peak season, that's your buffer. A two-to-three-day exam hold eats half of it. If the container doesn't clear by day five, demurrage charges begin: typically CAD 40 to 60 per TEU per day, depending on container size and hold reason.
At the warehouse, our in/out fees and handling charges add up fast. An importer paying in-bond holding rates plus drayage remobilization plus potential tariff re-assessment is looking at CAD 4,000 to 6,000 total cost per exam hold. One hold per month erases the tariff savings.
What Warehouse Ops Should Plan For
Plan for longer exam hold cycles. At FENGYE LOGISTICS, we have seven dock doors. If exam queue grows from one to three containers, cross-dock cutoff tightens. Staffing needs to shift. Drayage coordination gets tighter. Budget contingency.
If you run cross-dock operations, configure your cutoff SOP to account for two to three days of potential exam delay. Anything arriving after your primary cutoff needs to be routed for overnight holding or staged for weekend clearance. That costs money but prevents customer service surprises.

The Enforcement Timeline
This is not temporary US CBP enforcement blip. The White House document is formal policy. CBSA will align over the next two to three quarters. Expect more exams, longer holds, and broker scrutiny that sharpens. Importers using clean transshipment will be fine. Importers using transshipment to evade tariffs need to rethink their supply chain now, before CBSA escalates.
Transshipment itself isn't forbidden. Routing goods through intermediate jurisdictions for legitimate supply chain reasons is routine and legal. What's changing is enforcement scrutiny on transshipment designed to evade tariffs or trade remedy duties. Learn more about FENGYE Warehouse.
If your transshipment routing is clean, you're fine. If it's built on misrepresenting origin, fix it now. A CBSA exam is a process, but the cost and schedule impact are real. At FENGYE LOGISTICS in-bond cargo handling, we process exam-flagged containers every week. That's part of the job. But if your supply chain is designed to trigger exams, you need to rethink it. Talk to your broker about clean transshipment practices. Talk to your warehouse about exam hold contingency. Talk to your CFO about total landed cost including hold risk. Then decide if the transshipment routing still makes sense.
