Additional shipping costs can be stressful, especially when charged after your package has shipped. Carrier adjustments can add up, but fortunately, you can work to avoid them. Learn where to find adjustments, how carriers calculate these fees, and what you can do to prevent fees
What are carrier adjustments?
Adjustments are extra fees or credits added to your shipping cost after a carrier processes a package. The additional charges are calculated by subtracting the amount of postage paid for a shipment from the shipping costs that should have been paid. For example, you may have paid $10 in shipping costs. However, your shipment reaches USPS, and they find the shipping costs should’ve been $13. Your adjustment charge would then be $3.
Where to find adjustments
USPS and UPS adjustments can be found in your Stamps.com history. Keep in mind that there’s a delay between when an adjustment is given by a carrier and when the adjustment is shown in your account. To view adjustments, follow the steps below.
- Click on the History tab to view recent shipments. If a shipment was given an adjustment, it will be listed in the Adj. Amount column. Once you click on the shipment, you’ll see more information on why the adjustment was issued.
- To find these additional details, select the shipment to open the Order Details panel. In the example below, the adjustment was issued because incorrect dimensions were entered when the label was created.
USPS adjustments
Some of the most common reasons for adjustments include entering incorrect dimensions and weight as well as using/entering the incorrect packaging. As a reminder, the maximum weight for Priority Mail Flat Rate® Boxes (all sizes) is 70 pounds. Additionally, weight is rounded up. For example, if your shipment weighs 70.2 pounds, it will be rounded up to the nearest pound, making it too heavy for the service. Dimensions for Priority Mail Flat Rate® Boxes will need to be entered when creating your label as well.
Non-machinable surcharges
Another type of surcharge given by USPS is a non-machine surcharge. This surcharge is applied to pieces of mail and packages that aren’t able to be automatically sorted through USPS machines. Reasons a non-machinable surcharge might be issued include illegible addresses or non-traditional sizes that require these items to be manually sorted or assessed.
UPS adjustments
UPS® shipments can be up to 150 pounds and have a maximum length of 108.” However, if your package is over 50 pounds, it’s subject to UPS Additional Handling fees. UPS Additional Handling charges are extra fees applied to your shipping cost for shipments that need different handling. Some of these include:
- Packages with the longest side over 48” or the second-longest side over 30”
- Domestic shipments over 50 pounds and international shipments over 70 pounds
- Packages with a combined length and girth [ (2 x width) + (2 x height) ] of 105”
Common UPS surcharges
Three avoidable UPS adjustments are Over Maximum Size surcharges, Large Package surcharges, and Shipping Charge Corrections.
Over Maximum Size surcharges are extra fees applied to your shipments that exceed UPS’s sizes of 150 pounds, 108” long, and have a combined length and girth of 165”.
Large Package surcharges are extra fees applied to your shipments when:
- A domestic package’s length + girth are over 130”, or its length is over 96”
- An international package’s length + girth are over 130”
- Packages with a minimum billable weight of 90 pounds (except for UPS Ground®)
Shipping Charge Corrections are extra fees applied to each shipment with incorrect dimensions and/or weight. These charges are $1 per shipment, along with the additional shipping cost needed for the corrected dimensions and/or weight, and these shipments are also still subject to other surcharges like Additional Handling charges.
