Section 338 tariffs on CUSMA goods delay dock release and spike costs
Section 338 tariffs apply to Canadian imports, including goods that qualify for duty-free treatment under CUSMA. CBSA is now reassessing duty classifications on flagged goods, holding them at port pending reclassification. For warehouses and forwarders, this creates dwell time, drayage detention charges, and dock-to-stock SLA pressure.
CBSA reassessment is now routine. Plan for dock delays.
Section 338 tariffs apply to a wide variety of Canadian imports. The operational problem for your dock: CBSA is reassessing duty classifications on flagged goods regardless of CUSMA eligibility. A container arrives with a release that should move in 48 hours. But it gets flagged for reassessment. CBSA holds it while they determine the correct duty classification. Your dock-to-stock promise stalls.
This is not a tariff policy question. This is a dock problem.
The operational chain
A container lands at Port of Montreal. Broker sends PARS release. Goods get flagged for Section 338 assessment. CBSA places a hold pending reclassification. We routinely see 2–5 working day holds at FENGYE LOGISTICS' dock during reassessment. During that time, drayage detention is accruing by the hour. Your dock-to-stock window closes. In/out handling fees accumulate. Cross-dock cutoff for next-day outbound gets missed. Every hour of hold compounds into lost throughput.
The importer faces two paths forward. One: request Release on Payment (ROP). Goods clear dock, but duties remain owing as a contingent liability until the reassessment is final. CBSA approval is not automatic. Two: pay the assessed duty upfront to clear the hold immediately. Either way, the goods are not moving smoothly through the warehouse.
Port throughput and drayage detention
Port of Montreal containers come with free time. Once that window closes, detention charges apply hourly. If CBSA assessment extends into or beyond that free-time window, detention is running while goods sit waiting for reclassification. A truck scheduled for Tuesday pickup gets delayed to Wednesday because CBSA is still assessing. The driver faces detention charges. The importer absorbs the cost. If you're running a tight dock with consolidated pickups, one delay cascades into multiple trucks stuck waiting.
What this means for dock-to-stock SLA
If your SLA is 48-hour dock-to-stock and CBSA adds 3–4 days for assessment, the math breaks. You cannot promise 48-hour throughput when regulatory hold is outside your control. Port of Montreal does not absorb assessment delay. CBSA does not compensate for detention. Your warehouse handles the goods, but the timeline is no longer yours.
Most importers are starting to renegotiate SLAs with their forwarders and warehouses to account for Section 338 assessment hold. If your contract does not include a CBSA assessment dwell factor, add it. We typically see 2–3 additional working days built in as buffer now. If you do not add buffer, you will breach your commitments regularly.
Pre-classification is the winning move
The best defense is requesting an HS classification ruling from CRA before import. This takes 2–4 weeks but settles the classification question before goods arrive. CBSA tends to accept CRA rulings, which prevents dock reassessment hold. The cost is upfront, but the time saved in dwell and detention more than pays for it.
Work with your broker to identify products that fall under Section 338 scope. If there is any ambiguity in HS classification, request a CRA ruling. If you are importing 10–20 containers per month of the same product, a single ruling covers all future shipments.
Consolidation also reduces exposure. If you batch 3–4 shipments into a single container instead of importing them separately, you reduce the number of CBSA examinations. Fewer exams means fewer holds. FENGYE LOGISTICS consolidation services can coordinate goods pre-classification so they move as a single unit through assessment. The density improvement and reduced hold risk both improve cash flow.
What we see at dock weekly
Section 338 goods are now flagged routinely at Port of Montreal. Some importers accept the delay. Others request expedited assessment, which does not always succeed. A few contest the reclassification and move into formal appeals, which can add 4–8 weeks. None of these are fast tracks. We have stopped promising 48-hour dock-to-stock on any goods that fall under Section 338 scope.
Duty assessment hold is not negotiable. CBSA reassessment is a regulatory gate. Your warehouse cannot speed it up. Your drayage cannot bypass it. Your broker can request ROP or appeal classification, but that is a paper game with timelines outside dock operations.

Budget for duty as a contingency
Section 338 duty rate is 50% of goods value in most cases. If you import goods worth CAD 50,000 per container and CBSA denies ROP, the duty owed is CAD 25,000 to clear the hold. That is cash due immediately. If ROP is granted, it is still a contingent liability on your balance sheet. Either way, budget for Section 338 duty assessment as a working-capital expense in Q3 and Q4 planning.
If your supply chain is operating with tight inventory and fast-turn cross-dock cycles, Section 338 reassessment adds real friction. The dock window compresses. The cash requirement increases. The SLA risk rises. If your importers have not renegotiated for CBSA hold, they will start feeling it now.
Frequently Asked Questions
Will CUSMA coverage protect my shipment from Section 338 reassessment?
Not automatically. CBSA is reassessing classification on flagged goods regardless of CUSMA eligibility. If your product's HS code is ambiguous, request a CRA ruling before import — this takes 2–4 weeks but prevents dock reclassification hold. See <a href="https://www.cra-arc.gc.ca">CRA</a> for ruling procedures.
Can we request Release on Payment instead of paying duties upfront?
Possibly. CBSA may grant ROP if you provide security (bond or cash). If CBSA denies ROP due to high duty amount or classification dispute, you must pay to clear goods. Work with your broker to determine ROP eligibility before import.
How does Section 338 reassessment affect our dock-to-stock SLA?
Expect 2–5 working day hold at dock pending CBSA determination. If your SLA is 48-hour dock-to-stock, you need to renegotiate the timeline. In-bond handling at FENGYE LOGISTICS includes assessment dwell, but detention charges (truck and dock) are importer's liability.
What happens if I contest the Section 338 classification?
CBSA classification appeals take 4–8 weeks or longer. During appeals, goods remain in warehouse custody (in-bond). You accumulate in/out handling fees and potential storage charges. Most contested classifications resolve faster through broker negotiation or CRA ruling request before formal appeal.
Can we consolidate shipments to reduce Section 338 assessment risk?
Yes. If you batch 3–4 shipments per container instead of importing separately, you reduce examination count and hold exposure. Consolidation also improves pallet density and per-unit cost. FENGYE LOGISTICS offers consolidation services that can coordinate goods pre-classification.
What's the drayage detention window if CBSA is holding our goods?
Port of Montreal containers come with free time; detention charges apply by the hour after expiration. If CBSA assessment extends the hold, detention is accruing while goods sit on dock waiting for reclassification. See <a href="https://www.port-montreal.com">Port of Montreal</a> for current free-time and detention rate policy.
How do we know which products are flagged for Section 338 reassessment?
CBSA publishes the Section 338 product list on their website. Your broker should monitor it. The tariff applies to a broad range of products across multiple HS classifications. Request proactive HS ruling from CRA to prevent dock reclassification. See <a href="https://www.cbsa-asfc.gc.ca">CBSA</a> for the Section 338 product schedule.
Does Release in Bond still apply, or is everything Release on Payment?
RIB is still available for goods not flagged as high-duty-risk. ROP applies when duties must be paid or secured before release. CBSA determines which applies on a case-by-case basis. Section 338 goods are often subject to ROP pending duty determination and classification settlement.
