Port Base Linkage (PBL) / Base Port Surcharge
A surcharge applied when the port of loading or discharge is a base port (primary hub) with higher operational costs. Used by some carriers to differentiate pricing between base ports and outport/satellite terminals. Helps carriers manage volume distribution across terminals.
PBL varies by carrier and port pair. Using nearby feeder ports may eliminate PBL but add inland transport costs.
Who Pays?
Set by carrier or port authority — not negotiable.
PBL is a carrier pricing mechanism, not directly negotiable. However, shippers can reduce PBL by requesting delivery through outport/satellite terminals.
