USPS Surcharges, Fees, and New Policies Arrive Just in Time for the Holidays

Shipping with USPS is getting more complicated — and more expensive. Between new surcharges, dimensional weight rules, and the end of ounce‑based pricing, small businesses need to understand exactly what is changing.

Fuel & Holiday Surcharge

In April 2026, the USPS implemented a fuel surcharge for the first time in its very long history. The 8% surcharge aligns with all the other major carriers and covers all package services.

Starting October 4, 2026, another surcharge will be piled on. The Post Office’s annual USPS Holiday Surcharge will add an additional 8%.

Both surcharges are expected to end on January 17, 2026. I wouldn’t get my hopes up for lower prices, though. The Post Office is already planning to increase the postage rates to correspond with the end of the surcharges.

Elimination of Ounce-Based Pricing

Another major change impacting those businesses that ship small packages is the elimination of ounce-based pricing for Ground Advantage packages. This is specific to packages sent out at the commercial rate. For those of you using Shopify or a fulfillment provider, you were most certainly paying commercial rates and the deep discounts for under 12-ounces have been eliminated.

Dimensional Weight Changes & Error Fee

For many years now, postage rates for larger items have been based on their size instead of their weight, but significant changes to the calculations may cause some of the largest postage increases for some customers. There are two changes you need to know about.

First, the basic formula is length X width X height divided by a weight divisor that is divided by the Post Office. If the result is greater than 12, you pay based on the size of the package instead of the weight. For years, that divisor has been 166, but in July it was reduced to 139. This change will result in more packages being charged dimensional weight and an increased dimensional weight charge.

The second change is also significant. Prior to July 2026, the dimensional weight was rounded using standard rounding methods, but now all dimensional weights are rounded up, so if your package calculates to be 13.1 based on size, you are paying the 14 pounds, even if it only weighs 2 pounds.

So, what if you measure wrong? Well, you won’t just be asked to pay the additional postage due. Starting in January 2027, you will owe back the additional postage plus a fee. The exact amount of the fee hasn’t been announced; it is expected to be somewhere between $3 and $25 to align with the rest of the industry.

Rural Zip Code Fee

You read that right! Even though the USPS still delivers mail by mule in the Grand Canyon, they will no longer make the trek without an additional fee. For about 17,000 addresses (16% of rural Americans), there is now a fee ranging from $3.50 to $4.65 for delivery of packages to their rural address. For small businesses focused on sales of goods purchased by rural Americans, this fee represents a massive and sudden cost increase.

Your Business

So, what does all of this mean for you? Postage rates are always increasing but these sudden policy changes represent a significant increase for some small businesses.

I understand that this is a section of your business that can feel completely out of control, but there are things you can do. Here are 3 of the most important ways you can reduce the impact:

1. Compare Rates: FedEx and UPS often beat the USPS rates, particularly if you are willing to delay delivery by a day or two.

2. Select Perfect Fit Packaging: Sometimes I think that no matter how many boxes I have, I never have the perfect one. The perfect one is more important than ever, though. When possible, use poly mailers that can be reduced to fit the product perfectly and when a box is needed, get the right box or get a box resizer tool so you can make it a perfect fit.

3. Measure Correctly & Round Up: Are you in the habit of entering the box dimensions when you ship? The dimensions printed on the box are usually the inside measurements, and outside measurements can exceed that by up to an inch.  Always measure the package yourself and round up the dimensions.
