Export and Import Canada: How Blanked Sailings and Freight Rate Swings Affect Landed Cost and CARM Filings

Key Takeaways

• Freight rate volatility moves landed cost and cash flow but does not change Canadian customs duty or import GST, which are calculated on value for duty per Customs Act s.48.
• Blanked sailings compress vessel schedules and push cargo into concentrated arrival waves, overloading drayage queues and warehouse receiving docks even when CBSA clearance is fast.
• RPP bond sizing in the CARM Client Portal may need adjustment when freight cost swings push monthly import totals higher, triggering under-security flags.
• Canadian import operations should plan for inbound schedule variability and concentrated warehouse arrivals, not steady weekly drops, when carriers tighten capacity.

Spot Rates Climb as Carriers Blank More Sailings

Container spot freight rates on the three major east-west trades rose this week after a three-month post-peak slide. Shanghai-Rotterdam climbed 3% week-on-week to $3,632 per 40ft; Shanghai-Genoa and Asia-North America routes followed. Carriers are pulling strings from the schedule to tighten capacity and prop up pricing. For export and import Canada teams, that volatility doesn’t touch the customs duty line, but it reshapes landed cost forecasting, cash flow, and the warehouse and drayage windows you’re managing on the inbound side.

The distinction matters. Freight rate increases don’t change Canadian value for duty or the import GST calculation. Value for duty is the transaction value adjusted to the place the goods are shipped directly to Canada from, per Customs Act s.48. International freight and insurance from that point to Canada are excluded, as long as the amounts are documented and split out on the commercial invoice. But landed cost, the RPP bond you post in the CARM Client Portal, and the days your inventory waits for a container slot or dray window all move when ocean rates spike or carriers compress the sailing schedule.

Freight Rates Don’t Move Duty, But They Move Cash Flow

A container that was forecast at $1,200 and jumps to $3,600 is $2,400 more cash out the door per box before you see the goods. That moves your payment cycle, your working capital line, and the financial security amount you post for release prior to payment under CARM. Canadian customs duty and SIMA duty (when applicable) are calculated on value for duty, which excludes post-shipment freight. Import GST is 5% of value for duty plus customs duty plus excise, per Excise Tax Act s.215. Freight is not in that stack unless the supplier bundled it into a CIF or delivered price that nobody separated.

We routinely see clients re-size their RPP bonds mid-quarter when freight cost swings push their monthly statement of account total higher. The bond itself is sized as a multiple of estimated monthly duties and taxes, not freight, but a $2,400-per-container increase often coincides with higher import volumes (bringing in more boxes to beat the next rate hike) or a shift in product mix, and both of those do affect the bond calculation. The CARM portal flags under-secured accounts. The fix is filing an updated bond or posting a cash deposit to cover the gap. Duty and tariff advisory services include bond sizing and CARM reconciliation when freight markets turn volatile.

CARM Filing Timing and Blanked Sailings

CARM Release 3 went live October 21, 2024, and the CAD (Commercial Accounting Declaration) replaced the old B3 that same day. The monthly statement of account in the CARM Client Portal is now the system of record for duties and taxes owing. Blanked sailings compress vessel schedules, which tightens PARS pre-arrival filing windows and makes just-in-time CAD filing harder to coordinate.

A container you expected Wednesday now rolls to the following week’s string because the carrier blanked the mid-week sailing. Your HS 6-digit classification, CUSMA origin claim, and MFN duty rate don’t change, but the warehouse receiving window, the drayage detention clock, and the retail delivery commitment all do. PARS release is typically same-day if the CAD is clean and the entry is filed correctly, but getting the box from the port to your dock when the sailing schedule keeps shifting is where the cost and variability creep in.

Customs brokerage services include PARS coordination, CAD filing, and CARM statement reconciliation. The clearance itself is fast when the paperwork is right. The bottleneck is physical: container availability, dray capacity, and dock scheduling when half the week’s cargo drops in a 48-hour window instead of spread across five days.

Warehouse and Cross-Dock Implications

Blanked sailings push import cargo into concentrated arrival waves. A port that was steadily dropping 40 containers a week across five vessel calls now delivers 80 containers in two calls. That overloads the drayage queue, extends chassis detention, and fills the warehouse receiving dock faster than the outbound side can clear it.

For importers using bonded or sufferance warehousing, the timing crunch is worse. You can’t release cargo until CBSA clears it, and if the exam queue is backed up because half the port’s weekly volume arrived in 48 hours, your goods sit accruing storage fees while you wait. Duty and GST are unaffected, but all-in landed cost climbs every day the container sits.

FENGYE LOGISTICS operates a sufferance warehouse in Montreal with same-day CBSA coordination and a 14:00 cross-dock cutoff for next-day outbound. When ocean schedules compress and containers arrive in waves, that cutoff becomes the line between a one-day touch and a three-day hold. The customs side is handled; the constraint is dock doors, lift equipment, and how fast you can sort and reload outbound.

What Export and Import Canada Teams Should Watch

Spot rate volatility and blanked sailings are structural, not anomalies. Canadian import operations should track:

• Landed cost and working capital: Freight moves cash flow even though it doesn’t change customs duty or import GST (as long as it’s documented and excluded from value for duty per CBSA valuation rules).
• RPP bond sizing: If freight cost increases push monthly import totals higher, your CARM bond may need adjustment. Under-secured accounts get flagged; fix it before release is held.
• Inbound schedule compression: Fewer sailings mean tighter PARS windows and concentrated warehouse arrivals. Plan for cargo waves, not steady weekly drops.
• Drayage and detention: Concentrated arrivals overload dray capacity. If your warehouse can’t absorb a two-day surge, you pay detention and storage waiting for a slot.

The customs clearance workstream (CAD filing, HS classification, origin verification) is insulated from freight rate swings. The operational workstream (cash, timing, dock capacity) is not. They intersect at landed cost and the monthly CARM statement.

If your Q4 landed cost variance is driven by ocean freight and your RPP bond just got flagged for under-security in the CARM Client Portal, we run that reconciliation every week. Get in touch.

Frequently Asked Questions

Do higher ocean freight rates increase Canadian import duty or GST?

No. Canadian customs duty is calculated on value for duty, which excludes international freight and insurance from the point of direct shipment to Canada, per Customs Act s.48. Import GST is 5% of value for duty plus duty plus excise, per Excise Tax Act s.215. Freight affects landed cost and cash flow, not the duty or tax line.

When did CARM replace the B3 form for Canadian customs declarations?

CARM Release 3 went live October 21, 2024, and the CAD (Commercial Accounting Declaration) replaced the B3 that same day. The monthly statement of account in the CARM Client Portal is now the system of record for duties and taxes.

How do blanked sailings affect PARS filing and customs clearance timing?

Blanked sailings compress vessel schedules and tighten PARS pre-arrival filing windows. PARS release is typically same-day if the CAD is clean, but fewer sailing options mean containers roll to later strings, delaying warehouse arrivals and drayage scheduling even when customs clears fast.

What is an RPP bond and when do I need to adjust it?

An RPP (Release Prior to Payment) bond is financial security posted in the CARM Client Portal to release goods before duties and taxes are paid. The bond is sized as a multiple of estimated monthly duties and taxes. If freight cost swings or import volume increases push your monthly total higher, the CARM portal may flag your account as under-secured and require an updated bond or cash deposit.

Can I claim a refund if I overpaid duty because freight was included in the CIF price?

Yes. If your supplier’s CIF or delivered price included international freight and insurance that should have been excluded from value for duty, and you paid duty on the bundled amount, you can claim a refund under Customs Act s.74 within four years of the original payment, as long as the freight and insurance amounts can be documented and separated.

How long does CBSA typically take to release a container under PARS?

PARS (Pre-Arrival Review System) release is typically same-day if the CAD is filed correctly, HS classification is accurate, and no exam or verification is triggered. The delay is usually not CBSA clearance but drayage availability, warehouse receiving windows, and port congestion when multiple vessels arrive in a compressed schedule.
