基本海运费计算方法

1. Two Pricing Models for Sea Freight

Full Container Load (FCL)

Charged by the entire container, regardless of how much cargo is loaded inside.

Sea freight = Base Rate + Various Surcharges

Less than Container Load (LCL)

Charged by the Revenue Ton (RT)—the greater of weight or volume:

LCL freight = Rate × MAX(Weight (tons), Volume (CBM))
