FCL and LCL are two options for ocean shipping cargo. FCL involves one consignee filling an entire shipping container, while LCL allows multiple consignees to share space in a container. FCL is more secure as cargo is not mixed with others, but is more expensive since the entire container is rented. LCL is cheaper due to shared space but security is lower as cargo may get mixed or lost if not handled properly by the shipping company. Consignees should take measures like special packaging to protect cargo for both FCL and LCL shipping.
