Post-Shipment Billing Adjustments

Carrier adjustments are a frustrating reality of shipping that most shippers will have to deal with from time to time. These adjustments can affect your shipping costs and delivery timelines.

This article can help you understand what adjustments are, why they occur, and offer ways to minimize their impact on your business.

What are Adjustments?

Adjustments are charges or credits from the shipping carrier that are billed or credited to your Endicia account balance. Adjustments are typically made by carriers to ensure fair billing and accurate delivery. They can result in increased costs or delays in the shipping process. Adjustments are typically caused by factors like package weight, dimensions, delivery location, or service level.

Adjustments can sometimes appear from several days to several weeks after the ship date.

For carrier adjustments, an adjustment processing fee will be applied to cover administrative and other costs. See the section Adjustment Processing Fee for more information.

List of Common Carrier Adjustments

Below is a list of common adjustments by carrier. For further details about the types of adjustments a carrier may apply, please visit your carrier's website.

Common Adjustments for All Carriers

There are several reasons you might receive an adjustment, including (but not limited to):

  • A package that is an unconventional shape, like a cylinder or tube

  • Package dimensions exceed the service or carrier maximum

  • The package triggers dimensional weight pricing but no dimensions were entered prior to purchase

  • Saturday deliveries

  • The package is packed in something other than cardboard, such as wrapped in plastic or encased in metal

  • The recipient address is incorrect or incomplete

  • The label was attached incorrectly, so the barcode could not be scanned

  • Residential or out-of-area deliveries

  • Fuel surcharges or Peak surcharges

USPS automates much of its adjustment process with its Automatic Package Verification (APV) System. Other carriers use similar methods to ensure compliance with their shipment regulations.

USPS Adjustments

Non-Machinable Letter Surcharge

This USPS surcharge only applies to letters that cannot be automatically processed. 

The USPS relies on machines to automate the processing of its mail volume. To be processed by these machines, mail must have certain physical characteristics.

The following are common criteria for avoiding the surcharge on a letter:

  • Must bend easily. If a letter is too rigid or has uneven thickness, it may not pass through the machines.

  • Dimensions must be within 22" x 18" x 15” and weigh less than 25 lbs.

  • For pieces more than 4-1/4" high or 6" long, the piece must be at least 0.009" thick.

  • Delivery address must be parallel to the long side of the mailpiece.

  • For booklet-type pieces, the bound edge must be along the longest dimension, and cannot be across the top.

  • If the letter is a self-mailer (such as a bifold or trifold flier), the mailer should be securely closed at all openings (sides and front) with wafer seals or cellophane tape.

While still mailable, letters that do not meet these criteria are considered "nonmachinable" and due to this, incur additional postage charges.

If one or more of the following applies to your letter, click the Add'l Options button and select the Odd Shaped/Non-machinable checkbox:

  • It is polybagged, polywrapped, or enclosed in any plastic material.

  • Has clasps, strings, buttons, or similar closure devices.

  • Contains items such as pens or loose keys that cause the thickness to be uneven.

Large Package Surcharge

Packages larger than the dimension criteria will be subject to an additional charge, depending on the size. This surcharge does not apply to First Class and Media Mail packages.

The USPS criteria for large package surcharges:

  • If the longest side of a package is more than 22 inches but less than 30 inches, a $4.00 surcharge will be applied.

  • If the longest side of a package is greater than 30 inches, a $15.00 surcharge will be applied.

  • Packages with missing or incorrect package dimensions that result in any dimensions-based fees, a $1.50 surcharge will be applied.

  • If the volume of the package is greater than 2 cubic feet, a $15.00 surcharge will be applied.

    A square package 1 ft x 1 ft is one cubic foot. A square package 2 ft x 2 ft is two cubic feet (a 2 cubic foot square box is pretty big and well beyond the size of most packages) .

    For boxes that aren't square, measure the length, width, and height of your box in inches. Multiply the length, width, and height, then divide that total by 1,728. That is the exact cubic dimension of your package.

GlobalPost Adjustments

When configuring your GlobalPost shipments, we recommend always including the package dimensions in addition to the weight. GlobalPost uses dimensional weight, so even though dimensions are not required to create a label, adding the package dimensions will ensure you receive the most accurate rate. Because GlobalPost uses dimensional weight, in most cases where dimensions are not included for the shipment, you will receive a post-shipment adjustment back to your account for the difference in the rate paid versus the actual rate.

Visit GlobalPost Service Details to confirm the dimensions for your GlobalPost shipment.

Duties & Taxes with GlobalPost

GlobalPost Plus is Delivery Duties Paid (DDP), which requires the shipper to pay the fees. Any fees assessed at the border will be invoiced back to GlobalPost, which will then be deducted as an adjustment to your account balance after delivery.

Visit GlobalPost from Endicia for more information.

UPS from ShipStation is available to US, Canada, and UK-based ShipStation accounts.

How to Avoid Adjustments

The best way to avoid adjustments is to make sure you enter accurate weight and dimensions for every package you ship. This will ensure the correct rate is applied when preparing your shipping label. Entering accurate package information is the responsibility of the shipper. This is true for all carriers.

Other things to consider:

  • Use a postal scale. Don't guess! Using a scale, properly calibrated, helps ensure accurate weights.

  • For dimensions, round up fractional amounts: For example, 6.3 inches should be rounded up to 6.5 inches.

  • Check limitations for size or weight: Make certain you package is within any limitations the carrier or service has.

  • Use the smallest box: Using the smallest box that can contain proper packing materials will help avoid unnecessary surcharges, like the Dimensional Weight Surcharge.

  • Use sturdy packaging: Use materials that will not deform during shipping. A deformed package can, in some cases, exceed dimension limits for some services.

  • Indicate Special Handling: If your package is a non-standard shape or is not a corrugated cardboard box, it will require special handling. For example, boxes that are very long, very wide, or an odd shape (like tubes).

  • Get familiar with your carrier's rules: Some carriers have supplemental surcharges for delivery to certain areas. While these have been in place for many years, be sure you are aware of any extra costs.

Keep Track of Your Adjustments

  • In some circumstances, adjustments can put an account into a negative balance, which might also trigger overdraft protection with Automatic Postage Purchases. It is important to keep track of adjustments to avoid this.

  • Adjustments from non-USPS carriers do not display the reason for the adjustment within Endicia. For these adjustments, please compare your shipping information with that supplied by the carrier.

Review Your Account Adjustments

To review any adjustments that have been applied to your account:

  1. Click the HISTORY Tab and select an order that has an adjustment listed in the Adj. Amount column.

Adjustment Processing Fee

Endicia applies an adjustment processing fee when discrepancies are identified by a carrier after label creation for the package. These discrepancies lead to additional administrative and other costs for Endicia. The adjustment processing fee helps to partially cover these costs so that we can continue to offer you competitive rates and reliable service.

Some examples of scenarios that would incur an adjustment processing fee include:

  • Incorrect weight or dimensions: The actual weight or dimensions of a package exceeds what you input during the label creation process.

  • Incorrect zones: You mislabeled the destination zone of the package, changing the routing and delivery.

  • Incorrect package type: The package type you selected during the label creation process does not match the physical characteristics of the package.

Discrepancies are typically identified by the carrier during the carrier routing process. If a discrepancy is identified on a package, you will be charged the carrier cost adjustment amount in addition to an adjustment processing fee, which will be 20% of the carrier cost adjustment amount  up to a maximum adjustment processing fee of $1.00 per package.

You can view the adjustment processing fee for a package on the Balances Transactions Report.
