Shipping label adjustments

What is an adjustment?

A shipping label price adjustment occurs when carrier-audited package dimensions or weight are different than the inputs provided when the label was generated, or when additional services not included in the original label cost, were provided.

The difference is charged or credited to the original payment method (when possible) used to purchase the shipping label.

Common adjustment examples:

Inaccurate package dimensions or weight

Charges are incurred when carrier-audited measurements differ from the inputs provided when the label was generated, or when the weight or dimensions of the package, exceed the carrier’s weight and size restrictions.

Irregular/non-conforming package

There are also additional charges when shipping using non-standard packaging. This includes items that are not fully encased in a corrugated box or outer shipping container, and cylindrical-shaped items such as mailing tubes, buckets or pails.

Services added after calculating shipping

Charges can be incurred for services added after calculating shipping. These could include: Saturday delivery, address correction (rerouting package), future day pick-up, or on-call pick-up (if the sender does not have an account with UPS or FedEx).

What is DIM weight?

When estimating shipping costs, the size and shape of a package (dimensions) are just as important as weight. Measuring these correctly will prevent unwanted surprises such as additional charges or returned packages.

There are three key package measurements you may need to calculate shipping costs directly: Length, Girth and Dimensional Weight.

Length

Girth

Length is the longest side of the package, rounded up to the nearest inch.

Girth is the ‘distance’ or circumference around a package. It’s important to know because most carriers have maximum girth limits. Girth for rectangular packages = 2 x width + 2 x height. Girth for cylindrical packages = circumference of the cylinder.

Dimensional weight

ALWAYS round up

This is NOT the package’s weight on a scale, but a number reached by calculating the package’s height x length x width, divided by applicable carrier DIM divisor. Billable shipping is based on whichever cost is greater — the dimensional calculation or the actual scale weight of the package.

For both dimension and weight measurements, always remember to round up to the nearest whole number.

Once you have these numbers and the scale weight, use eBay’s Shipping Calculator to determine shipping costs for your package.
