Shipping costs are rising again — but not in the way many B2B ecommerce operators modeled as carriers weigh surcharges.
Across the U.S. parcel market, the United Parcel Service (UPS) and FedEx, are relying more heavily on surcharges, rather than base rate increases, to offset higher fuel, labor, and network costs. And now, the U.S. Postal Service (USPS) plans to add temporary 8% package-shipping surcharge for the remainder of 2025 and through most of January 2027.
The shift is making fulfillment more complex and less predictable, with direct implications for how B2B ecommerce companies’ price, sell and deliver goods online.
Both UPS and FedEx implemented general rate increases of about 5.9% for 2026, consistent with prior years. But that headline figure masks a broader pricing shift. Surcharges tied to fuel, delivery area, handling and package size are now the primary drivers of total shipping cost.
Fuel surcharges are emerging as the most volatile component, and they are now being amplified by macroeconomic pressures tied to rising oil prices.
Shipping carriers plan surcharges to account for war-inflated fuel prices
In a recent research note, Goldman Sachs said it raised its inflation forecast and lowered its economic growth outlook as oil prices climb following disruptions tied to the Strait of Hormuz. The U.S. and Israel’s war on Iran has led to closures and other disruptions to key pathways for global fuel transportation and supply chain networks at large.
“Our strategists now expect Brent oil prices to average $105 in March and $115 in April before falling to $80 in the fourth quarter of 2026,” the firm said. “We have raised our inflation forecasts and lowered our GDP growth forecast a touch further.”
Goldman Sachs said it now expects headline personal consumption expenditures (PCE) inflation to reach 3.1% by December 2026, with core PCE at 2.5%. It lowered its gross domestic product (GDP) growth forecast to 2.1% for 2026. It also increased the probability of a recession to 30%.
“The war will raise inflation in a few ways but should have a moderate impact on the core,” the firm said.
It noted that energy price passthrough alone could add about 0.35 percentage points to core inflation this year.
Higher energy costs are flowing directly into transportation pricing. Because fuel surcharges are indexed to energy benchmarks and updated frequently, increases in oil prices are quickly reflected in parcel shipping costs.
Carriers have made clear that surcharges are a central part of that pricing strategy. On a recent earnings call, a FedEx executive said fuel pricing “was very helpful” to per-package revenue, underscoring how surcharges are being used to offset cost inflation and support margins.
Fuel surcharges indicate structural shift for B2B ecommerce operations
The shift is spreading across the market. USPS hasn’t yet implemented surcharges, but it said it is planning to introduce a temporary one for fuel on package services. That would be a first time, as the carrier cited rising transportation costs.
In its announcement, the agency said the change reflects “elevated inflationary pressures and increased transportation costs,” bringing its pricing structure more in line with private carriers.
For B2B ecommerce, the implications of fuel surcharges are structural.
As more procurement moves online, business buyers are placing smaller, more frequent orders, often with expectations shaped by consumer ecommerce:
- Fast delivery
- Real-time pricing
- Full transparency
That shift increases the cost-to-serve per order while exposing companies to a wider range of surcharges tied to shipment characteristics.
At the same time, surcharge logic is becoming more granular. Carriers are expanding fees tied to dimensional weight, oversize thresholds and extended delivery zones. Those factors are common in B2B shipments involving industrial parts, building materials and multi-line orders. These charges are often applied simultaneously, compounding total fulfillment cost.
Impact of increased shipping costs on B2B ecommerce
The result is a growing disconnect between digital pricing and actual delivery cost. Many B2B ecommerce platforms still rely on simplified shipping models, such as flat-rate pricing or static freight thresholds. Those models struggle to account for dynamic surcharges that can change weekly and vary significantly by order profile.
That gap is becoming harder to absorb as pricing becomes more dynamic and less transparent. Carriers are increasingly applying incremental pricing changes throughout the year, often outside of traditional contract cycles, making it more difficult for ecommerce operators to maintain margin consistency.
The pressure is forcing B2B ecommerce companies to rethink fulfillment as a core part of pricing strategy. Many are embedding real-time freight calculations into checkout, redesigning packaging to reduce dimensional weight exposure and reconfiguring fulfillment networks to shorten delivery distances and reduce zone-based charges.
Carriers, meanwhile, are using surcharges to more precisely price delivery complexity. Higher fees are increasingly tied to shipments that are heavier, larger or delivered to less-dense areas, allowing carriers to align pricing more closely with cost-to-serve while keeping base rates stable.
The result is a structural shift in parcel economics. Shipping is no longer a predictable line item. It is a variable, data-driven cost that directly shapes margins, pricing accuracy and customer experience in B2B ecommerce.
Rising oil prices and carrier surcharge strategies are turning shipping into the most volatile cost in B2B ecommerce, forcing companies to align digital pricing, fulfillment and margin management more tightly with real-time delivery costs.
