FedEx AHS and Oversize Costs Hit January 12, 2026

In January 2026, FedEx is implementing structural changes to how it assesses packages, moving beyond standard dimensional weight to include new cubic volume and weight thresholds for major surcharges. While a general rate increase (GRI) of 5.9% took effect on January 5, 2026, more significant dimensional-related changes begin on January 12, 2026. 

Key dimensional & assessment changes are as follows:

1. New surcharge triggers (effective January 12, 2026)
   • Additional Handling Surcharge (AHS), Dimension applies to packages with cubic volume over 10,368 cubic inches.
   • Oversize Charge applies to packages with cubic volume over 17,280 cubic inches.
   • Oversize Charge also applies to packages with actual weight over 110 lbs.
2. Standard dimensional weight rounding
   • FedEx rounds up any fraction of an inch to the next whole inch when calculating dimensional weight.
3. Surcharge rate increases
   • Dimensional and weight based surcharge rates increased for 2026.
   • Increases vary by zone.
   • Example: Oversize Charge increases range from 5.8 percent to over 30 percent.
4. Other related changes
   • Home Delivery surcharges apply per package starting January 12, 2026.
   • International Additional Handling weight threshold reduced to 55 lbs.

If left unaddressed, this becomes another cost increase layered on top of:

• 2026 5.9% GRI (base transportation rates)
• December fuel surcharge increase already impacting budgets

This is not a minor adjustment. For the wrong carton profiles, it can create significant, unbudgeted spend.

What Parcel Shippers Should Do Now

1. Identify Packaging and Carton Optimization Opportunities

• Reducing dimensional and handling triggers
• Lowering cubic exposure on high-volume SKUs
• Improving carton discipline and right-sizing practices

2. Address the Exposure Through Contract Strategy and Negotiations

• Solving this only operationally is risky.
• Engage with ebb Logistics and let them evaluate contract-based strategies to reduce the financial impact without disrupting your operations. 

Negotiating surcharges in isolation can be challenging, but it becomes far more achievable when supported by clear modeling and a structured negotiation plan that ebb Logistics can provide.
