Poshmark will stop covering extra postage on overweight packages on October 26, 2026. Value Added Resource reported the change on October 17, citing Poshmark’s October 8 announcement. Sellers who skip the right label upgrade will see the difference come out of their earnings.
That puts the shipping risk on the person packing the box. For resellers who work from a spare room, a missed scale check now costs real money.
What Poshmark Changed
The standard label covers packages up to 5 pounds. A 5.01 to 10 pound package needs a $5 upgrade, and a 10.01 to 15 pound package needs a $10 upgrade.
If a seller ships a package of 15.01 to 25 pounds on a single label, Poshmark deducts $15. Above 25 pounds, it deducts the full USPS shipping cost. The rule hits anything near the limits, from boots to bundled lots. Upgrades only reach 15 pounds, so heavier orders should ship as multiple boxes with separate labels.
Poshmark has not explained why it is ending this protection. Sellers who ship regularly should check every scale reading before printing a label. The report adds that the change does not touch the existing label upgrade rates.
Why This Matters For Self-Employed Resellers
Poshmark sellers run on thin margins. A coat, a pair of boots or a bundle of kids’ clothes can land near a weight limit. A wrong guess on the scale can cost $5 to $15 per sale.
The change also stacks with earlier moves. Poshmark ends its subsidy of the USPS hazardous materials fee on October 19, according to the same outlet. That leaves sellers owing the full $50 penalty.
Taken together, the platform now pushes more risk onto individual sellers. Resellers who treat the shop as a business should price that risk into every listing.
The deduction also lowers your payout on a sale you already priced. The loss lands after the buyer is happy, which makes it easy to miss.
What Self-Employed Resellers Should Do Next
Buy a cheap digital postal scale and weigh every item after you box it. Weigh the packaging too, since mailers and padding add up. When a package crosses a limit, buy the upgrade before you ship.
Next, review your listings and your pricing. Heavy items may need a higher price or a clear note about shipping. For bulky orders, split the sale into boxes ahead of time, and check your hazmat items against USPS rules now.
Track the cost in a spreadsheet for the next month. If deductions show up often, raise your prices or drop the heaviest items from your shop. A clear record also helps at tax time, since shipping costs are a business expense you can report.
What To Watch Next
Watch for Poshmark to explain the change. Value Added Resource says it is unclear whether the $15 charge matches the true USPS cost.
Holiday volume will test the new rules quickly. Our guide to holiday shipping surcharges for solo sellers covers the other costs landing this season. Compare Poshmark’s rules with other marketplaces before the holiday rush, since each platform handles postage differently.
