Peak Shipping Surcharges 2026: Re-Cost Before the First One Lands

The first 2026 peak surcharges take effect on 27 September (UPS) and 28 September (FedEx). If you are reading this in September, that is days away, not weeks.

Most brands treat carrier surcharges as a November problem, which is understandable, because the expensive tier does land in November. But the cost starts accruing in late September, and the decisions that change your exposure (which SKUs ship in which box, and where the free-shipping threshold sits) take three to four weeks to implement.
