Understanding Carrier Rate Adjustments
Understanding Carrier Rate Adjustments
Carrier rate adjustments are additional charges or credits applied after a label is purchased. Understanding why they happen helps you manage costs.
What Are Rate Adjustments?
Definition: Rate adjustments are billing corrections made by carriers when the actual shipment differs from what was declared at label purchase.
Common Types:
| Adjustment | Cause |
|---|---|
| Weight | Actual weight differs |
| Dimensions | Package larger than declared |
| Address correction | Carrier fixed address |
| Zone | Different delivery zone |
| Service upgrade | Service level changed |
Why Adjustments Happen
Weight Adjustments:
- Scale wasn't calibrated
- Packaging weight not included
- Content changed after label
- Carrier weighed differently
Dimensional (DIM) Adjustments:
- Package larger than declared
- DIM weight exceeds actual weight
- Irregular package shape
- Box bulging
Address Corrections:
- Incorrect ZIP code
- Missing apartment/suite
- Wrong street spelling
- Outdated address

How to Minimize Adjustments
Accurate Measurements:
- Use calibrated scale
- Include packaging weight
- Measure at widest points
- Round up, not down
- Weigh after packing
Correct Dimensions:
- Measure length × width × height
- Include any bulges
- Consider irregular shapes
- Use DIM weight calculator
Address Validation:
- Use address validation before shipping
- Include apartment/suite numbers
- Verify ZIP codes
- Include recipient phone
DIM Weight Explained
Formula:
DIM Weight = (L × W × H) ÷ DIM Factor
USPS: DIM Factor = 166
UPS/FedEx: DIM Factor = 139
Example:
Box: 12" × 10" × 8" = 960 cubic inches
DIM Weight: 960 ÷ 139 = 6.9 lbs
If actual weight is 3 lbs,
you'll be charged for 7 lbs (DIM weight)
