USPS 421 Retail Clerk Practice Exam

The oversize surcharge applies to parcels that exceed the maximum size limit set by the USPS. Specifically, parcels that measure more than 108 inches but no more than 130 inches in combined length and girth are subject to this surcharge. This fee is necessary to account for the additional handling and transportation requirements associated with these larger packages, which can affect shipping efficiency and costs.

Understanding this surcharge is essential for accurately calculating shipping costs and advising customers about potential fees. Other surcharges, such as the dimensional weight surcharge, pertain to different criteria related to the package's dimensions compared to its weight. Similarly, the additional handling fee targets packages that require special handling due to their unique characteristics, while the parcel post surcharge refers to specific categories of postal services rather than general size restrictions.
