Key Takeaways
- Feeder vessels above 8,000 TEU are now calling Montreal and Halifax, shortening port dwell and advancing cargo-ready cutoffs by six to twelve hours.
- CAD filing under CARM Phase 2 Release 3 requires the cargo control number at time of submission, so late manifest amendments delay release.
- Cross-dock facilities receiving mixed LCL from these larger feeder calls need tighter inbound appointment windows to keep detention charges off the importer.
- Importers relying on release prior to payment should confirm their RPP bond covers the higher per-voyage duty exposure when two weeks of shipments arrive in a single call.
Bigger ships, tighter windows
Container lines have been cascading larger vessels onto short-sea and feeder trades for the past eighteen months, and the effect is starting to show up in Canadian port calls. The Port of Montreal now sees regular feeder services operated by ships in the 6,000 to 8,500 TEU range, a jump from the 2,000 to 4,000 TEU feeders that were the norm three years ago. Halifax has seen similar upsizing on its transatlantic feeder strings.
The operational consequence is straightforward: two weeks of cargo that used to arrive across four separate sailings now shows up in a single twenty-four-hour discharge window. That compresses the timeline for customs clearance, drayage appointment slots, and cross-dock throughput. If your brokerage workflow still assumes you have forty-eight hours between vessel berthing and container availability, you are already behind.
CAD filing and cargo control numbers
Under CARM Phase 2 Release 3, which went live in May 2024, brokers file the Commercial Accounting Declaration (CAD) through the CARM Client Portal. The CAD replaces the old paper-and-EDI B3 process, and it requires a valid cargo control number at the time of submission. That number ties your declaration to the carrier's eManifest, which CBSA receives under section 12.1 of the Customs Act.
When a 8,000 TEU feeder discharges two hundred and fifty Montreal-destined containers in a single shift, the terminal's container-availability list updates faster than most importers expect. If your broker does not have advance notice of the cargo control number, the CAD sits in draft status while the container racks up per-diem charges at the terminal. We routinely see twelve to eighteen-hour delays when an importer forwards the bill of lading but forgets to confirm the CCN with the carrier.
The fix is procedural: as soon as the vessel departs the last European or Caribbean port, ask your carrier for the cargo control number and forward it to your broker. That gives the broker time to validate the HS classification, confirm the CUSMA or CETA origin certificate if applicable, and queue the CAD for release prior to payment. Waiting until the ship berths in Montreal means you are filing in parallel with two hundred other importers who all want their containers off the dock by noon.
Release prior to payment and bond exposure
Many Canadian importers use an RPP bond to release goods before paying duties and taxes. CBSA calculates the required bond amount based on the highest estimated duties you will owe in any thirty-day period. When your inbound freight pattern shifts from four smaller weekly sailings to two large biweekly calls, your peak exposure climbs.
Example: an importer brings in CAD 400,000 of dutiable goods per month, spread evenly across four shipments. CBSA expects roughly CAD 100,000 per week. If the carrier consolidates that volume into two 8,500 TEU feeder calls, each call now carries CAD 200,000 of duty exposure. If your existing RPP bond was sized for the old weekly cadence, CBSA will either ask you to post additional security or require you to pay duties at time of release until the bond is topped up.
We have seen three importers in the last quarter hit this ceiling after their Mediterranean feeder service switched from a weekly 3,500 TEU string to a fortnightly 8,000 TEU rotation. In each case, the importer's CARM Client Portal flagged insufficient security, and the broker had to arrange a same-day wire payment to clear the release.
If you are not sure whether your bond covers the new vessel schedule, pull your last K84 monthly statement from the CARM portal and compare the peak single-transaction duty total against your posted security. The gap will tell you whether you need to call your surety.
Cross-dock and drayage scheduling
Larger feeder vessels also tighten the window for cross-dock operations. A 2,500 TEU feeder discharging over two shifts gives drayage carriers and warehouse operators a staggered flow of container pickups. An 8,000 TEU feeder discharging the same Montreal-bound box count in a single shift compresses that flow into six to eight hours.
FENGYE LOGISTICS operates a bonded sufferance warehouse in Lachine with a same-day cross-dock cutoff at fourteen hundred hours. Containers that clear CBSA and arrive at the dock before that time can be deconsolidated, sorted, and loaded onto outbound LTL or parcel carriers the same business day. Anything that arrives after fourteen hundred sits overnight and incurs per-diem storage.
When four smaller feeder calls spread the inbound flow across four weeks, most importers easily hit the cutoff. When the same volume lands in two calls, half the containers now arrive on the same day, and appointment slots fill fast. Importers who do not pre-book drayage and confirm their CAD filing status the morning of vessel discharge routinely miss the window.
The other variable is CBSA examination. If your shipment is flagged for a physical exam, count on losing twenty-four to forty-eight hours. CBSA does not prioritize exams based on your cross-dock cutoff, so any container selected for verification will sit at the terminal until the officer completes the inspection and updates the release code in the CARM system. That delay is outside your broker's control, but it is predictable enough that you should build it into your inbound planning if your HS 6-digit classification or country of origin tends to draw scrutiny.
HS classification and duty planning
Larger feeder vessels do not change the tariff treatment of your goods, but they do change the financial consequence of getting the HS classification wrong. When you import CAD 50,000 of goods per shipment and the correct duty rate is 6.5 percent MFN instead of zero under CUSMA, the error costs you CAD 3,250. When the feeder consolidation doubles your shipment size to CAD 100,000, the same misclassification costs CAD 6,500.
If you are filing your own CADs through the CARM Client Portal and you are not confident in the HS code, use the HS classification tool before the vessel sails. Correcting a classification error after release is possible under CBSA's D17-1-10 memorandum, but the correction window is ninety days, and any additional duty owed will appear on your next monthly CARM statement with interest calculated from the original accounting date.
We also see importers underestimate the interaction between vessel size and SIMA (Special Import Measures Act) enforcement. If your goods are subject to anti-dumping or countervailing duties, CBSA applies those margins at the time of CAD filing. A larger per-voyage shipment means a larger up-front SIMA payment, and if your RPP bond does not cover the combined MFN duty plus SIMA margin, you will be asked to pay before release.
Manifest amendments and late documentation
One operational trap that larger feeder vessels expose: late manifest amendments. Carriers sometimes update the container count, seal number, or bill-of-lading reference after the vessel has sailed. Under the old four-smaller-ships pattern, a manifest amendment on Tuesday still left time to refile the PARS or update the broker's paperwork before the Friday discharge.
With an 8,000 TEU feeder, the discharge happens within hours of berthing, and a manifest amendment submitted the morning of arrival will not propagate through CBSA's eManifest system before your container is available for pickup. The result: your CAD references an outdated cargo control number, the CARM portal rejects the submission, and your container sits at the terminal until the broker refiles with the corrected CCN.
The only mitigation is to confirm with your carrier that the manifest is locked forty-eight hours before the vessel's estimated time of arrival in Montreal or Halifax. If the carrier cannot commit to that timeline, plan for a twenty-four-hour clearance buffer and do not promise your customer same-day delivery.
What this means for your clearance process
If your carrier has switched to larger feeder vessels in the last six months, review three things: your RPP bond ceiling, your broker's cargo-control-number handoff procedure, and your cross-dock appointment lead time. All three variables tighten when two weeks of freight lands in a single call.
We file CADs for Montreal and Halifax feeder cargo daily. If your current process is built around smaller, more frequent sailings and you are starting to see clearance delays or bond-insufficient flags in the CARM Client Portal, get in touch. The vessel schedule is not going back to 2,500 TEU ships.
Frequently Asked Questions
What is a CAD and when do I need to file it?
The Commercial Accounting Declaration (CAD) replaced the old B3 form under CARM Phase 2 Release 3, which went live in May 2024. You file the CAD through the CARM Client Portal before or at the time of release, and you must include a valid cargo control number tied to the shipment's eManifest.
How does a larger feeder vessel affect my customs release timeline?
A single 8,000 TEU feeder can consolidate two weeks of smaller sailings into one port call, which means the entire batch hits the terminal within a twenty-four-hour discharge window. If your broker does not have the CAD ready at first availability, your container sits behind everything else in the stack.
Do I need a larger RPP bond when my carrier switches to bigger ships?
Possibly. CBSA requires RPP bond security to cover the highest estimated duties and taxes you will owe in any thirty-day period. If your carrier now lands two weeks of inventory in a single voyage instead of spreading it across four weekly calls, your peak exposure climbs, and CBSA will ask you to post additional security or pay duties at time of release.
What is a cargo control number and why does CARM care about it?
The cargo control number links your CAD to the carrier's eManifest filed with CBSA under section 12.1 of the Customs Act. Without a matching CCN in the CARM Client Portal, the system will not accept your declaration, and your goods cannot be released.
Can I amend the HS classification on a CAD after the container is released?
Yes, but only within ninety days of the original accounting date. CBSA's D17-1-10 memorandum sets the correction window, and any changes that increase duty owed will trigger a supplementary payment demand through your CARM monthly statement.
How do I know if my goods need CFIA clearance before CBSA will release them?
CBSA's eManifest system flags shipments that require other-government-department (OGD) approval. If CFIA holds the release, you will see the hold code in the CARM Client Portal, and your broker cannot finalize the CAD until the agency issues its import permit or safe-food inspection certificate.
What happens if my container misses the cross-dock cutoff at the Montreal warehouse?
The container will sit overnight, and you pay per-diem storage until the next available outbound departure. FENGYE LOGISTICS publishes a fourteen-hundred cutoff for same-day cross-dock at the Montreal sufferance facility; anything that clears CBSA after that time rolls to the next business day.
