The United States Postal Service (USPS) has changed the way it calculates certain Ground Advantage shipping rates, removing an ounce-based pricing structure that had given some sellers more precise package costs.
The adjustment affects how merchants using the service view and calculate shipping expenses, with some online sellers raising concerns about the short notice surrounding the change.
USPS Removes Ounce-Based Rates From Ground Advantage Pricing
The change centers on the USPS Ground Advantage service, a shipping option widely used by small businesses, marketplace sellers, and individuals sending packages across the United States.
According to The Sun, the Postal Service removed ounce-based rates from its published pricing charts after reviewing its position against other shipping providers. The update means customers will now see rates structured more closely around industry-standard pricing models rather than the previous ounce-by-ounce system.
A USPS spokesperson explained the decision in a statement to The U.S. Sun, saying,
“The Postal Service’s ounce-based rates were unique in the marketplace – none of our competitors offered these types of rates.”
The spokesperson added,
“After evaluating the Postal Service’s competitive position, we eliminated the ounce-based rates from our published rate charts to better align with industry practices.”
For many customers, the direct financial effect may appear limited in individual shipments. The larger concern among some sellers is how quickly pricing structures can change and how those adjustments affect businesses that depend on predictable shipping expenses.
Small online retailers often calculate product margins based on precise delivery costs. A change in shipping calculations can influence pricing decisions, inventory strategies, and the way sellers manage customer expectations.

Sellers Raise Concerns Over Short Notice Of USPS Adjustment
Some sellers reacted negatively to the timing of the update, arguing that businesses need more transparency when shipping costs change.
One seller wrote on a discussion board,
“The concerning part isn’t the ten cents, it is the fact the USPS can now implement random changes with less than 24 hours notice.”
The comment reflects a broader concern among some merchants who rely on shipping platforms and automated pricing tools. Even minor changes can require updates across online stores, marketplaces, and fulfillment systems.
For larger companies, shipping adjustments can be absorbed through existing operations. Smaller sellers often have fewer options when transportation costs shift because shipping represents a significant portion of their operating expenses.
The discussion also highlights the growing importance of stable logistics pricing in online commerce. Businesses selling lower-cost products are especially sensitive to small increases because shipping fees can represent a large share of the final customer payment.
The Ground Advantage service was introduced as a competitive shipping option designed to simplify package delivery while replacing several previous USPS ground shipping products. The service has become a common choice for sellers looking for affordable domestic delivery.
USPS Says The Change Aligns With Industry Practices
The Postal Service said the pricing update was designed to bring its published rates closer to those used by competing carriers.
The move comes as shipping companies continue adjusting their pricing systems in response to changing market conditions, customer demand, and competition in the delivery sector.
The USPS maintains that the removal of ounce-based rates creates a more consistent structure compared with other major carriers. The agency has continued efforts to position Ground Advantage as a flexible option for consumers and businesses.
For sellers, the impact will depend on package sizes, shipping volume, and existing agreements with logistics platforms. Some businesses may see minimal changes, while others could need to adjust their shipping calculations.
The update also shows how changes in postal pricing can quickly become a major issue for independent merchants. Many rely on detailed cost tracking to maintain profitability in competitive online marketplaces.
Shipping Costs Remain A Key Issue For Online Businesses
The USPS adjustment arrives during a period when businesses continue monitoring delivery expenses. Shipping remains one of the most visible costs connected to online purchases, affecting both sellers and consumers.
While the immediate change may not dramatically alter every shipment, merchants are paying close attention to future updates from major carriers. Predictable pricing remains a priority for businesses managing tight margins.
The Ground Advantage change demonstrates how even small modifications in logistics systems can create wider discussions among sellers. As e-commerce continues to expand, shipping policies from companies such as USPS will remain closely watched by businesses that depend on reliable delivery networks.
