Have you ever noticed a gap between your quoted April rates and your July invoice, even when using the same lane, pallet count, and carrier? Your July invoices are significantly higher than the other months. This isn’t a billing mistake. It is your LTL freight pricing that is evolving in response to:
This is further compounded by the movement of bulky freight, including seasonal retail goods, outdoor equipment, agricultural products, and construction materials.
In this guide, we will address each of these constraints to analyze how each increases your invoice value until the cumulative effect erodes your profits.
Understanding LTL freight costs is the key to ensuring shipping freight efficiency and controlling transportation costs. In LTL (Less-than-truckload) shipping, shipments from multiple businesses are consolidated into a single vehicle. This helps save costs but also introduces a few extra cost variables, not present in an FTL invoice. These variables make the LTL cost result dependent on the packaging, classification, and routing of the freight.
The LTL shipping rates are calculated using certain core pricing components. They include:
This is the foundation of almost all LTL pricing and is calculated using CWT or hundredweight pricing. Here, the cost is based on the weight per 100 pounds. So, in most cases:
A key factor affecting LTL rates, the freight class is determined by the density per cubic foot, the handling requirements, the stowability, and the liability or risk of damage or theft of the shipment.
Density is the most critical factor of LTL shipping rates. Typically, a heavier, tightly packed pallet with higher density earns a lower class and a lower rate, while a bulky, lightweight, low-density shipment earns a higher class as it carries less overall weight.
Another key component that helps determine LTL freight rates in Canada impacts pricing in the following ways:
This is calculated as a percentage on top of the base charge and updated regularly. It helps account for fuel price fluctuations. Other market conditions that can also impact LTL pricing include:
These include everything that lies outside the purview of standard dock-to-dock services. Common accessorials include liftgates, residential delivery, inside delivery, and limited-access fees. These do not appear on the original LTL shipping rates but are levied once the shipping and fulfillment service provider understands your shipping needs and moves your cargo.
These are the least visible components. Lane pricing gives you an idea about the competitiveness of a given origin-destination pair. Capacity adjustments allow for a discreet widening of margins when:
These adjustments are done quietly, without changing the published rate table.
All of the above land on the final invoice. Summer disrupts almost every one of these components at once, which is exactly why the quote you get in April rarely survives to July.
Freight capacity isn't fixed. Seasonal demands have a major impact on them. Sectors like agriculture, retail, and construction see higher shipping volumes in summer. This rise triggers changes in logistics networks.
Freight rates shift as carriers compete for space, market conditions change, and demand overpowers supply. In summer, this additional demand results in capacity constraints triggered by:
Produce season peaks in the summer months, and it pulls both reefer and dry van trailers toward agricultural lanes first. Carriers chase the freight that pays the most reliably, and in July and August, that's often produce moving out of growing regions on tight harvest windows.
Vacation season and a persistent driver shortage compound at exactly the wrong time. Fewer available drivers means fewer trucks running. LTL is more exposed to this than truckload, because a single driver shortage on a regional run can delay a dozen shippers' freight sitting on the same trailer.
Road construction ramps up in the same months freight volume peaks. As a result, regional trucking capacity gets pulled toward hauling materials, equipment, and aggregate for active job sites.
For Canada-US lanes specifically, summer brings more trucks to the border simultaneously. Inspection volume rises, and this delay means a trailer stuck in a queue for an extra hour isn't available for its next load. This compounds across a fleet running dozens of cross-border trips a week.
This is the part most shippers miss. A rate increase in July doesn't necessarily mean your lane got longer or your freight got heavier. It usually means the carrier has more freight competing for the same trailers than it did in March, and pricing is the mechanism that manages that imbalance. So, scarcity sets what you actually pay.
Each of these factors amplifies the summer-season demand-driven freight squeeze by adding pressure on the system.
One thing inflating your July invoice isn't seasonal at all, which is why it's easy to miss. Your freight class may have moved since May, when NMFTA's Docket 2025-1:
Docket 2026-1 continued it, taking effect on May 23, 2026, much after most shippers had already priced their spring lanes.
Anything you tender for delivery in the United States rates against NMFC regardless of where the trailer is loaded. As a result, a Canadian shipper running domestic freight on a carrier's own tariff and US-bound freight on NMFC is now maintaining two classification logics at once.
This failure mode is silent. Get the class wrong, and the carrier reweighs, remeasures, reassigns, and rebills you using a higher rate plus a reclassification fee. Repeat offenders often lose negotiated discounts. None of that shows up at booking. It surfaces on an invoice weeks later, by which point the same wrong class has gone out on fifty more shipments.
But it's worth mentioning that the NMFC can potentially increase your surcharge year-round. What makes brands more vulnerable in summer is the huge increase in shipment volumes, which makes it easy to make freight-class errors.
The summer peak months witness a steep rise in the surcharges. In fact, for most carriers, surcharge collections may at times exceed expenditures, turning the surcharge into a profit center. As carriers continue to revise the fuel surcharge calculation formula, this fuel surcharge revenue will hold firm, with eCommerce companies bearing the majority of this expenditure.
As a business owner, this will significantly impact your shipping costs and profit margins. Coupled with this, the unpredictability of fuel surcharges and their fluctuating nature:
Different carriers have their own approach to calculating and implementing fuel surcharges. Some might adjust it based on the weekly diesel price published by the US Energy Information Administration. Some might use the US Gulf Coast(USGC) prices for kerosene jet fuel as the benchmark.
But irrespective of what they are based on, you just see the output on your invoice as a surcharge line that noticeably increases in summer when fuel charges tend to rise.
| Strategies to Manage LTL Fuel Surcharges | |
| Strategy | Why it helps |
| Negotiate a flat rate with your carriers | To lock in surcharge on high-volume shipments |
| Use a digital logistics platform | To compare rates across carriers |
| Optimize pallet density | To move to a lower class and a lower rate per hundredweight |
| Consider alternative shipping methods | To lower fuel surcharges |
| Plan shipments strategically | To reduce surcharge-eligible loads |
This represents one of the most frustrating cost centers for eCommerce brands. These additional fees are charged for services that go beyond standard pickup and delivery. For example, they can transform an affordable $350 quote into a budget-busting $739 expense.
Yet they are all legitimate fees. These compensate your carrier for the extra work, additional time, and specialized equipment they use to transport your shipment from origin to destination. But most eCommerce brands do not understand whether the additional charges applied on their invoices actually apply to their shipments.
With accessorial fees an integral part of LTL freight pricing, a company with a high volume of LTL shipments sees them compound into tens of thousands of dollars. But they can be avoided with proper planning and strategy.
This can be attributed to many factors. But primarily, LTL shipments move through a shared network of terminals, and freight costs are split among multiple shippers. This often requires extra services like:
Thus, LTL shipments add-on variables that increase their costs. These costs are unpredictable in nature and vary widely across carriers and contracts. They are rising because of:
Let’s look at a few instances that can increase accessorial charges on your summer invoice.
The classification shift above doesn't just change freight class. It interacts with accessorials too. A shipment that is reclassified to a higher class under the new density rules can also trigger accessorial reviews, particularly if it requires special handling due to its size. For freight that's already bulky and seasonal, that's two separate cost increases stacking on the same shipment.
Construction season doesn't just tighten capacity; it changes routes. Detours around active construction zones can:
Soon, limited-access and liftgate fees add up as line items on your invoice. These charges rarely appear in the original quote because the carrier doesn't know about a detour until the truck is en route.
This is the fee category shippers most consistently underestimate. A single unexpected liftgate charge, inside delivery fee, or reclassification penalty can be larger than the entire rate difference between two competing carrier quotes. This means the carrier comparison shippers spend the most time on often isn't where the real savings sit. The accessorial line items are.
These aren’t rare edge cases. They are the everyday cost of shipping LTL. Here’s a quick snapshot of the likely accessorial charges that are most likely to hit your invoice in summer and what strategy you can adopt to minimize their impact.
| Summer Accessorial Charges to Watch(And How to Avoid Them) | |
| Accessorial charge | Strategies to reduce it |
| Liftgate / limited-access fee | Confirm dock access at booking and flag construction zones or gated sites upfront |
| Reclassification fee | Measure and weigh the packed pallet before booking, and verify the NMFC code on the bill of lading against the current density scale |
| Residential delivery fee | Declare residential addresses accurately to avoid misclassification |
| Redelivery / missed appointment fee | Schedule delivery appointments in advance and confirm consignee availability |
Cross-border shipments have to face certain unique constraints. These added layers further squeeze Canada-US LTL costs. These include:
Summer brings higher overall truck volume at the border, plus seasonal produce shipments that draw additional agricultural inspection. Staffing at most crossings doesn't scale proportionally with volume, and the queue bears the brunt. A shipment that would clear in minutes in February can sit considerably longer in July, purely because more trucks are competing for the same inspection lanes.
Commercial freight entering Canada requires a PARS (Pre-Arrival Review System) filing. On the other hand, freight entering the US requires the equivalent PAPS filing. Both need to reach customs before the truck arrives at the crossing.
The most common reason a shipment gets pulled into secondary inspection isn't the freight itself. It's the mismatch between the commercial invoice, the bill of lading, and the customs filing. A declared value that's different by one line, or a product description that doesn't quite match the classification, is enough to trigger a hold. In peak summer congestion, it can cost hours.
The FAST (Free and Secure Trade) program gives pre-approved carriers, importers, and drivers a dedicated, faster lane at major crossings. The catch is that eligibility requires every party in the chain, including the carrier, importer, and manufacturer, to be enrolled.
A single non-enrolled supplier disqualifies the entire shipment from the fast lane. This is why most shippers assume they have FAST access and still end up in the standard queue. It's worthwhile to confirm enrollment across your full supply chain before assuming this benefit applies.
You can negotiate a strong base rate and still lose the summer to one reclassification and a liftgate fee. The shippers who hold costs steady aren't the ones with the sharpest contract; they're the ones running quotes through a platform like eShipper before they book.
Shippers managing rising LTL freight costs during peak season have used this kind of platform-level visibility to hold freight spend steady even as underlying market conditions tighten. Let’s look at the ANS case study where ANS Performance’s business grew by over 400% because of shifting to more efficient LTL shipment management. ANS Performance is a leading Canadian sports nutrition brand. While it had scaled its B2B operations to serve over 400 customers, its logistics management was holding it back. eShipper offered an alternative in the form of SmarteFreight for LTL shipments. By transitioning from a fragmented third-party broker to eShipper’s fully managed in-house solution, ANS Performance could optimize freight costs and efficiency, leading to its phenomenal growth.

Summer doesn't inflate LTL freight pricing through one mechanism. Capacity constraints, classification, fuel surcharges, accessorials, and border congestion move in at the same time, each one compounding the others.
The freight class reform alone would be worth watching this year. Paired with a fuel index running well above last summer's levels and a border that's slower for everyone, the invoices you're seeing now aren't an anomaly. They're the system working as designed under seasonal pressure. The businesses that manage this best aren't the ones who negotiate the lowest base rate; they're the ones who can see which line item is about to move before it does.
This is a very relevant question. Shippers can start by separating their base rate from the variable components like fuel surcharges and accessorials, since those move independently and unpredictably.
They can also track the weekly diesel index if your carrier’s surcharge is tied to it. Further, building a seasonal buffer into their freight budget for June through August specifically also helps, especially when capacity and border congestion both peak.
Also reviewing last year’s actual invoices against quoted rates for the same months is a more reliable forecasting baseline than this year’s quote alone.
Consolidating smaller shipments into fewer, larger loads reduces the number of separate base rates and separate fuel surcharges you’re paying across a given period.
Auditing your freight classification against the current density-based standard can also reveal your loopholes where you’re paying a higher class than your actual shipment density requires.
Lastly, comparing quotes across multiple carriers in real time, rather than relying on a single carrier relationship, also helps uncover new opportunities to save.
Density is now the primary factor in freight classification for most commodities, following the 2025-2026 NMFC reform. A denser shipment earns a lower freight class and a lower rate; a bulky, lightweight shipment earns a higher class and pays more, even if it weighs less overall. Repackaging to reduce empty space or consolidating multiple boxes onto a single pallet can measurably lower your effective freight class.
Watch your accessorial charges as a percentage of total freight spend, not just your base rate. This is where unexpected costs concentrate. Track your fuel surcharge rate against the current diesel index to confirm your carrier’s table is calculating it correctly.
For cross-border shipments, monitor how often they are pulled for secondary inspection, since a rising rate usually indicates a documentation issue worth fixing at the source.
Yes, generally. Rates differ by direction because of imbalanced freight flows. This refers to more volume typically moving in one direction than the other on a given lane, impacting:
A quote for one direction should never be assumed to apply to the reverse lane. Platforms like eShipper that pull live multi-carrier quotes account for this directional difference automatically rather than requiring a separate manual check.
