May brings a variety of fee increases from USPS, UPS, and FedEx, with updates hitting international shippers across multiple cost categories. 

From air fuel adjustments to demand surcharges to disbursement and duty-related fees, these mid-year changes are a reminder that carrier pricing doesn’t follow a predictable annual cycle. Staying current on surcharge activity and understanding how each update affects specific shipping lanes is essential for accurate budget forecasting.

UPS Shipping Surcharge Updates – May 2026

International Air Fuel Surcharge

  • Effective Date: May 11, 2026
  • Details: UPS is adjusting its U.S. International Air-Export and International Air-Import Fuel Surcharge rates. Full rate details are available in the UPS International Air Fuel Surcharge guide.
  • Why It Matters: Air fuel surcharges are among the most volatile cost line items in international shipping. Shippers moving high-priority freight via UPS international air services should review the updated rates and factor them into lane-level cost projections.

Paper Commercial Invoice Services Surcharge

  • Effective Date: May 11, 2026
  • Details: The Paper Commercial Invoice Services Surcharge will increase to $40.00 per shipment.
  • Why It Matters: For shippers still processing paper commercial invoices, this fee can add up fast, especially at volume. Transitioning to electronic commercial invoicing where possible is one straightforward way to avoid this charge entirely.

Disbursement Fee

  • Effective Date: May 11, 2026
  • Details: The minimum charge for the UPS Disbursement Fee will increase to $17.00.
  • Why It Matters: The Disbursement Fee applies when UPS advances funds on a shipper’s behalf to clear customs, such as paying duties or taxes. As that minimum climbs, cross-border shippers should evaluate whether their customs payment processes are structured to minimize how frequently this fee is triggered.

What’s The Difference Between Disbursement Fees and Duty and Tax Forwarding Fees?

The key difference between these two surcharges is who owes what and when:

  • Disbursement Fee: Charged when the carrier advances money on the shipper’s behalf to pay duties, taxes, or other customs charges upfront to clear the shipment. The carrier essentially fronts the funds and bills the shipper back. The fee is the cost of that service.
  • Duty and Tax Forwarding Fee: Charged when the carrier collects duties and taxes from the recipient (rather than the shipper) and forwards that payment to customs. The carrier is acting as a middleman between the recipient and the customs authority.

FedEx Shipping Surcharge Updates – May 2026

International Demand Surcharge Expansion

  • Effective Date: May 7, 2026 (until further notice)
  • Details: FedEx has expanded its international demand surcharges to include a significantly broader set of export destinations. Most notably, Canada (Zones A and B) and Mexico are now subject to a $0.20 per pound charge on parcel and freight shipments, with a $1 per shipment minimum for parcels and $50 for freight.
  • Why It Matters: Demand surcharges were historically reserved for markets experiencing instability or capacity constraints. Expanding them to Canada and Mexico represents a meaningful cost increase for shippers with regular cross-border volume. Shippers should audit affected lanes and factor these per-pound charges into cost projections. Read more about import demand surcharges and export demand surcharges.

International Fuel Surcharge Adjustment

  • Effective Date: May 11, 2026
  • Details: FedEx has updated its international fuel surcharge table, with rates indexed to the USGC fuel price per gallon of jet fuel. Export surcharges range from 37.00% to 38.50% and import surcharges from 41.25% to 42.75%, depending on the current index value. The current table applies while the USGC index falls between $3.75 and $4.03.
  • Why It Matters: International fuel surcharges fluctuate with market conditions and apply across a broad range of FedEx international services. Shippers with consistent cross-border volume should monitor index movements closely, as rate changes can occur without advance notice.

USPS Shipping Surcharge Updates – July 2026

Dimensional (DIM) Weight Calculation

  • Effective Date: July 12, 2026
  • Details: USPS is updating how dimensional weight is calculated for competitive shipping services, including Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select. Two specific changes take effect for packages exceeding 1,728 cubic inches (one cubic foot):
    • New DIM Divisor: The divisor used to calculate dimensional weight will drop from 166 to 139 — the same divisor used by FedEx and UPS for daily rates. A lower divisor means dimensional weight will calculate higher, resulting in more packages being billed on size rather than actual weight.
    • Updated Rounding Rules: USPS will adopt a “round up” rule for all package dimensions. Any fraction of an inch must be rounded up to the next whole inch. For example, a package measuring 12.2 inches on one side will be calculated as 13 inches.
    • Full details are available in the USPS PostalPro announcement.
  • Why It Matters: USPS has historically used a more favorable DIM divisor than FedEx and UPS, making it an ideal option for shippers of large, lightweight parcels. With the divisor moving to 139, that cost advantage narrows. Combined with the rounding rule change, shippers of bulky, lightweight packages will see dimensional weight billing apply to a wider range of shipments. Shippers relying on USPS Ground Advantage as a cost-effective option for oversized lightweight goods should model the impact before July 12.

What Do These New Shipping Surcharges Mean for Your Shipping Budget?

May’s updates share a common thread: international shipping costs are rising across multiple fee categories. For shippers with cross-border volume, the compounding effect of air fuel surcharge adjustments, higher disbursement minimums, and increased duty and tax forwarding fees can add up quickly.

A few areas worth reviewing now:

  • Identify which shipments regularly exceed the $800 customs value threshold and model the updated FedEx fee impact on those lanes
  • Evaluate whether paper commercial invoice processes can be shifted to electronic to avoid UPS’s $40.00 per shipment charge
  • Review how duty and tax responsibilities are assigned in your shipping agreements to minimize exposure to forwarding and disbursement fees
  • Factor updated UPS international air fuel surcharge rates into cost projections for time-sensitive freight
  • Audit your USPS Ground Advantage, Priority Mail, and Parcel Select volume for packages exceeding one cubic foot (these shipments will be subject to the new 139 DIM divisor and round-up rules starting July 12)
