The independent reference for ocean liner shipping

Every export shipment moves under a paper trail of three letters and a check digit. Those four-letter container prefixes — the ISO 6346 owner code — tell you who actually owns the box, who controls the equipment, and which carrier you should call when the container goes missing. ContainerPulse maintains the most comprehensive open registry of those codes on the public web. We profile 265 ocean carriers spanning the global majors, regional intra-Asia operators, Mediterranean feeders, niche reefer specialists and the dozens of NVOCC brands that fly their own prefixes. Each profile lists the carrier's BIC prefix list, fleet size, headquarters, alliance membership and the trade lanes they actually call.

Ocean shipping is an opaque industry, but it does not have to be. We publish working route corridors with realistic transit days, port-pair frequency information, and the complete carrier rotation that calls each pair. We document every standard ISO container format from a 20' general purpose dry box up to a 40' high-cube reefer, with internal dimensions, payload limits and cubic capacity drawn from the IICL and ISO 668 standard. And we cover the ocean alliances — the Gemini Cooperation, Premier Alliance, Ocean Alliance, MSC Standalone Network — that determine which vessels carry your cargo on the East-West trades.

ContainerPulse is built for working professionals: forwarders triaging a tracking ticket, supply-chain analysts modelling capacity scenarios, ocean carrier sales teams checking competitor coverage on a corridor, and the long tail of independent NVOCCs who need to verify a partner's footprint before signing a service contract.
