SOC and COC

Your container or the carrier's?

SOC and COC differ in who provides the container. Sigma Container sells and leases SOC containers as an alternative to equipment supplied by the shipping line.

SOC

Shipper-owned container (SOC)

Use a container you own or lease independently, rather than one supplied by the shipping line.

  • Greater control over equipment use and shipment planning
  • Potential savings on carrier equipment charges; port and terminal charges may still apply
  • No carrier return deadline; any lease terms still apply
  • Suitable for regular import and export operations
COC

Carrier-owned container (COC)

The shipping line provides the container for the shipment.

  • No container purchase required
  • Return deadlines and conditions set by the carrier
  • Demurrage and detention charges may apply after the agreed free time
  • Suitable for occasional shipments

Intermodal container and equipment supply

Check a container number and look up the registered owner/operator code in the BIC register.

ISO 6346 · BIC CODE

Container number check

Enter the 11-character number (e.g. CSQU 305438 3). We check the format and check digit and link to the BIC owner/operator code record. This does not verify the container's existence, current ownership or condition.
