Navigating the 2026 Carrier Rate Increases
by DimMath Logistics Team Carriers
The 2026 General Rate Increase (GRI) is officially here, and for most sellers, it means a baseline increase of 5.9% across standard services. However, the “headline” rate rarely tells the full story.
Dimensional Weight Impacts
Carriers have tightened their scanner tolerances at major hubs. This means that even a bulging box corner can trigger a higher DIM weight bracket. We recommend using our DIM Weight Calculator for every shipment to ensure you are accounting for these changes.
Surcharge Stacking
Fuel surcharges remain volatile, but the biggest impact this quarter is the new “Large Package Surcharge” threshold. If your package length plus girth exceeds 105 inches, you may see a flat fee increase regardless of actual weight.
How to Mitigate Costs
- Audit your box sizes: Moving from a 12x12x12 to a 10x10x10 can save significant costs in DIM weight fees.
- Consolidate shipments: Shipments that were previously two packages might now be cheaper as one larger “cubic” shipment via USPS.
- Verify every rate: Use our tools daily to stay ahead of the carrier scanners.
