Standard Cartons Are the Safest Default for Express and Parcel Networks
Courier delivery channels generally perform best with clean, standard cartons that keep labels readable and package shapes predictable. Non-standard cartons, wrapped units, and non-carton packaging may still move, but fee exposure or carrier restrictions become more likely.
Standard cartons usually create the least operational friction.
Accepted without surcharge: standard carton packaging.
Reinforced, wrapped, strapped, or surcharge-prone cartons should be confirmed in advance.
Accepted with possible surcharge: non-standard cartons, over-wrapped cartons, banded units, or cartons with structural add-ons.
Some non-carton formats may be restricted depending on the carrier and route.
Higher-risk formats: wooden boxes, flight cases, drums, or unusual non-carton units in parcel networks.
