The headline change: cubic volume now drives surcharges
Historically, AHS and/or LPS surcharge eligibility was determined primarily by:
- Length
- Length + girth
- Weight
- Packaging
In 2026, both carriers added cubic volume (L × W × H) as an additional trigger.
New thresholds (aligned across both carriers):
- Additional Handling Surcharge (AHS)
→ Triggered at > 10,368 cubic inches - Large Package / Oversize Surcharge (LPS)
→ Triggered at > 17,280 cubic inches or > 110 lbs.
This means packages can now incur surcharges even if they do not violate traditional length or girth thresholds.
Of note, shippers should monitor their invoicing to ensure any AHS and LPS discounts previously negotiated will apply to the new cubic thresholds. Because this is a new charge, previously negotiated discounts may not apply.
How FedEx implemented the change
Effective January 12, 2026, FedEx expanded its surcharge logic to include cubic volume across both tiers:
Additional Handling – dimension
Now applies when:
- Cubic volume exceeds 10,368 in³.
- OR existing triggers (length, weight, packaging) are met.
Oversize Charge
Now applies when:
- Cubic volume exceeds 17,280 in³.
- OR weight exceeds 110 lbs.
- OR traditional length + girth thresholds are exceeded.
Key takeaway:
FedEx did not replace existing rules—it layered cubic volume on top, increasing the likelihood of surcharge exposure.
How UPS implemented the change
Effective January 26, 2026, UPS introduced nearly identical cubic logic:
Additional Handling charge
Now triggered when:
- Cubic volume exceeds 10,368 in³.
- OR traditional size/weight/packaging rules apply.
Large Package surcharge
Now triggered when:
- Cubic volume exceeds 17,280 in³.
- OR weight exceeds 110 lbs.
- OR length + girth thresholds are exceeded.
Like FedEx:
- Cubic volume is additive, not substitutive.
- If LPS applies, AHS is not charged (UPS standard hierarchy).
Why this matters: more packages now trigger fees
The addition of cubic volume closes a major “loophole” that many shippers unknowingly relied on.
Example (Additional Handling):
A package measuring:
- 36 × 17 × 17 inches = 10,404 in³
Previously:
- Avoided Additional Handling based on length + girth being 104 inches, under the 105-inch trigger.
Now:
- Exceeds 17,280 in³ → automatically triggers AHS
Example (Large Package):
A package measuring:
- 46 × 24 × 16 inches = 17,664 in³
Previously:
- Avoided Large Package based on length + girth being 126 inches, under the 130-inch trigger.
Now:
- Exceeds 17,280 in³ → automatically triggers LPS
What this signals from carriers
This change is not random - it reflects a broader shift in carrier strategy:
1. Pricing for space, not just weight
Carriers are increasingly focused on network efficiency:
- Bulky, lightweight shipments consume trailer and aircraft space.
- Cubic thresholds directly target high cube, low-density freight.
2. Expansion of accessorial revenue
These rules:
- Increase the percentage of shipments incurring AHS/LPS.
- Drive real-world increases above the headline GRI.
3. Standardization across carriers
UPS and FedEx are:
- Using identical cubic thresholds.
- Applying parallel logic across surcharge tiers.
This reduces arbitrage opportunities and reinforces consistency in duopolistic pricing structures. This signals that both carriers prefer not to ship these packages in the first place, but if they do, they plan to charge hefty penalties.
Operational impact to shippers
Shippers most affected by these changes include:
- E-commerce brands shipping large, lightweight items.
- Furniture, fitness, and outdoor goods.
- Companies with inefficient cartonization.
- Shipments near dimensional thresholds.
Even small dimensional changes—or rounding—can now:
- Push shipments over 10,368 in³ (AHS)
- Or over 17,280 in³ (LPS)
What to watch going forward
The introduction of cubic triggers signals a long-term trend:
- Greater reliance on multi-variable pricing models.
- Increased importance of packaging engineering.
- Continued expansion of surcharge-based pricing.
For most organizations, the biggest risk is not understanding which shipments are near these thresholds.
Bottom line
The 2026 changes from UPS and FedEx represent a structural shift in parcel pricing:
- Cubic volume is now a primary determinant of surcharge eligibility.
- More shipments will trigger Additional Handling and Large Package fees.
- Cost exposure is expanding—often without changes to product or demand.
Organizations that can quantify how their shipment profiles interact with these thresholds will be best positioned to manage the impact.
How Loop helps you quantify and control the impact
Loop is a logistics data platform that connects carrier pricing rules to your actual shipment data, so you can see how these changes show up in your cost structure.
With Loop, you can:
- Quantify how often additional handling and large package surcharges are triggered.
- Identify the specific SKUs, cartons, and lanes driving that exposure.
- Analyze how your carrier agreements translate those triggers into real costs.
- Model how packaging or contract changes would shift your overall spend.
This gives you a clear view into how the 2026 rules are affecting your network and where to act.
