USPS filed proposed shipping-price changes on November 12, targeting January 17, 2027. The announcement pairs an average 5.9% domestic shipping increase with a proposed 11% fuel surcharge.

Treating either number as the change to your label will give you the wrong answer.

These are proposals subject to Postal Regulatory Commission review. The USPS price-change page labels its January files as proposed, so there is time to model the impact before touching customer-facing prices.

Separate the Rate Increase From the Fuel Change

The November 12 announcement names Priority Mail, Priority Mail Express, Ground Advantage, and Parcel Select among affected domestic services.

The fuel piece replaces April's temporary 8% transportation adjustment with a permanent mechanism, initially set at 11%, with a review scheduled for July 2027.

The new surcharge would not apply to international products at this stage. USPS separately proposes an average 7.9% increase across specified international services, including Priority Mail International and First-Class Package International Service. Those are portfolio averages rather than a promise that every country, weight, or service moves equally.

Reuters independently reported the proposal. Neither headline percentage tells an ecommerce business what its parcel bill becomes.

Eleven Percent Is Not Eleven Percent More Than Today

The existing adjustment decides your comparison. Do not add the proposed 11% to a current price that already carries the 8%.

Assume eligible postage of $10. An 8% adjustment makes it $10.80. An 11% adjustment makes it $11.10. The increase is 30 cents, roughly 2.78% against the previously adjusted amount.

Add a change to underlying postage and the answer shifts again. Do not sum 5.9 and 11, and do not apply both percentages to an already adjusted label. Use the proposed rate files and whatever pricing treatment your label provider confirms.

Holiday pricing creates a second comparison trap. The 2026 temporary holiday schedule runs through the start of January 17. Comparing a November label against a January quote mixes the removal of seasonal charges with new permanent pricing.

Your Label Provider Is Part of the Calculation

A published postal price and the amount charged by a marketplace, shipping platform, or fulfillment partner are different things. Ask which January schedule applies to your account and whether the displayed quote already includes the fuel component.

eBay changed Ground Advantage rates twice in one week last month, which is a useful reminder that marketplace labels need their own audit. That change does not set your January price.

Build a sample from recent orders covering your common weights and zones, plus packages that barely cross a weight or dimensional threshold. Record the carton your warehouse actually uses rather than the dimensions saved at launch.

For each shipment, keep the current paid amount, the proposed January amount, and any assumption your provider has not confirmed. Keep estimates out of the same column as verified quotes.

Update Contribution Before Touching Free Shipping

The number that matters is dollars lost per order multiplied by orders shipped.

An extra 40 cents across 3,000 monthly parcels costs $1,200. If those orders previously contributed $4 each after variable expenses, that removes 10% of contribution.

Start with products carrying low contribution and expensive delivery profiles. A blanket price increase makes nearby lightweight orders less competitive while leaving distant heavy orders underpriced.

Before January, get account-specific quotes, confirm how your provider handles the surcharge, and save the final approved schedule. Then test your free-shipping threshold against the resulting order mix.

The document that matters next is the final rate treatment for your account, not another national average.
