Sea freight, also known as ocean freight, is one of the longest established forms of transporting goods internationally. It’s also one of the most economical. While air freight is favored for time-sensitive shipments, sea freight is still the first choice for many businesses and individuals looking for a cost-effective solution. Sea freight services were revolutionized by the introduction of containerization after the Second World War—loading ships with standardized containers allowed a greater volume of cargo per vessel and removed the need for warehousing. Today, the majority of sea cargo is transported in either TEU (twenty foot equivalent unit) or FEU (forty foot equivalent unit) containers. With unitedshippingslogistic , you have the option to book either an FCL (full container load) at one of those sizes, or an LCL (part container load) if you don’t have enough cargo to fill a whole container at either of those sizes.
