What Is a Large Package Surcharge?
A Large Package Surcharge (LPS) is applied to packages that exceed specific dimensional thresholds but remain within the carrier’s maximum size limits. It’s distinct from (and more expensive than) the Additional Handling Surcharge.
2026 Large Package Surcharge Rates
| Carrier | Threshold | Surcharge |
|---|---|---|
| UPS | Length + Girth > 130” | $115.00 |
| UPS | Cubic volume > 5,184 in³ | $115.00 |
| FedEx | Length + Girth > 130” | $115.00 |
Girth formula: 2 × (Width + Height)
A package measuring 50” × 25” × 20” has:
- Length + Girth = 50 + 2(25 + 20) = 50 + 90 = 140” → triggers LPS
Large Package DIM Weight Override
When a package triggers the Large Package Surcharge, carriers apply a special DIM weight rule:
Large Package DIM Weight = (Length × Width × Height) ÷ 139
The key difference: for large packages, the minimum billable weight is the greater of:
- Actual weight
- DIM weight
- 90 lbs (UPS minimum for large packages)
This means even a 10 lb item in a large box will be billed at a minimum of 90 lbs plus the $115 surcharge.
What Are Unauthorized Surcharges?
An unauthorized surcharge (sometimes called an “undeliverable” or “prohibited” surcharge) is applied when a package violates the carrier’s terms and conditions — typically by exceeding maximum size or weight limits.
Common Triggers
| Trigger | Maximum Limit | Surcharge |
|---|---|---|
| Weight exceeds 150 lbs | 150 lbs | Package refused or $500+ penalty |
| Length exceeds 108” | 108 inches | Package refused or penalty |
| Length + Girth exceeds 165” | 165 inches | Package refused or penalty |
| Improper DG shipping | Varies | $500–$10,000+ fine |
Consequences Beyond the Surcharge
Unauthorized shipments can result in:
- Package refusal at origin sort facility
- Return to shipper at shipper’s expense
- Account suspension for repeated violations
- DOT/IATA fines for dangerous goods violations (up to $500,000+)
How Large Package and Unauthorized Charges Stack
For packages that trigger the Large Package Surcharge, the total cost accumulates rapidly:
Example: 45 lb package, 55” × 25” × 22”, Zone 6, residential
| Charge | Amount |
|---|---|
| Base rate (90 lb minimum, Zone 6) | $47.50 |
| Fuel surcharge (8.5%) | $4.04 |
| Large Package Surcharge | $115.00 |
| Residential delivery | $6.95 |
| Total | $173.49 |
Despite the actual weight being 45 lbs, you’re paying for 90 lbs (large package minimum) plus the $115 surcharge. The LPS alone is 66% of the total cost.
Strategies to Avoid Large Package Charges
1. Disassemble Before Shipping
If a product can ship in a smaller form factor when disassembled (furniture, equipment, displays), the packaging cost savings can be dramatic.
2. Split Into Multiple Packages
Two medium packages may be cheaper than one large package, even counting the additional base rates. Run the math:
| Option | Cost |
|---|---|
| 1 large package (triggers LPS) | ~$173 |
| 2 medium packages (no LPS) | ~$60 × 2 = ~$120 |
| Savings from splitting | ~$53 |
3. Use LTL Freight
For consistently large items, LTL freight rates are almost always cheaper than parcel + LPS. The service level is slower, but the economics are compelling.
4. Negotiate LPS Rates
Some high-volume shippers negotiate reduced LPS fees, though carriers have less flexibility here than on smaller surcharges.
5. Measure Precisely
Carrier dimension scanners measure the conveyable footprint of a package, which may be larger than the box itself if the box has irregular shapes or protruding parts. Ensure your packaging is rectangular and uniform to avoid scanner inflation.
The Bottom Line
Large Package and Unauthorized surcharges are the most punitive fees in parcel shipping — designed to discourage oversized packages from entering the parcel network. At $115+ per package plus a 90 lb minimum weight, any product that consistently triggers these thresholds should be evaluated for freight shipping, repackaging, or product redesign. The parcel network simply isn’t built for these packages, and the pricing reflects that.
