Meaning
Port logistics tariffs impose escalating daily financial penalties when freight containers remain inside shipping terminals past allowed free time allowances. Managing demurrage exposure requires logistics managers to track incoming resin shipments and tooling containers from vessel discharge to gate departure. The liability boundary begins the moment designated free days expire at port terminals and terminates when empty containers return to ocean carrier custody.
Terminal Dwell
Inland transportation delays and missing import documentation delay container movement away from marine terminals. High demurrage exposure emerges when imported polyolefin resins sit at port facilities awaiting customs clearance or laboratory sampling. Plant managers must align resin delivery schedules with available warehouse bay space to prevent unnecessary container holding penalties.
Storage Penalty
Daily container penalties accumulate on a compound schedule, rapidly inflating the total landed cost of raw materials. Extended demurrage exposure directly erodes gross margins on high-volume moulded part contracts where resin costs represent the majority of part pricing. Logistics contracts must clearly allocate financial responsibility between freight forwarders, raw material suppliers, and processing facilities.
Clearance Timing
Pre-clearing customs documentation prior to vessel arrival reduces terminal dwell time for raw polymer shipments. Reducing demurrage exposure depends on rapid coordination between customs brokers and transport carriers. Streamlined paperwork prevents costly container holds at container yards.
