PSS
Category: Logistics
Also searched as: Peak Season Surcharge
Definition (plain English)
Peak season surcharge is an added freight charge during high-demand shipping periods.
Why it matters commercially
PSS can erase margin if quotes are accepted without seasonal surcharge and validity checks.
Example
A holiday import moved into peak season and required a revised landed-cost model after PSS applied.
Common mistake
Using off-season freight rates for peak-season cargo without checking surcharge exposure.
