About ContainerPulse
ContainerPulse is built and maintained by a small editorial team of supply-chain professionals who got tired of the same three problems: opaque carrier directories that haven't been updated since 2015, container prefix lookups that return paywalled answers, and "transit time" calculators that quote one-vessel-direct numbers when every shipment in the real world trans-ships at least twice.
So we built the reference we wished existed. Our database covers 265 ocean carriers indexed by their ISO 6346 owner prefix, 34 working trade-lane corridors with realistic transit-time reporting, 6 ocean alliance profiles, and the complete inventory of 15 standard ISO container formats. Every page is human-edited, every figure is referenced to public carrier data, and every record is updated on a quarterly cadence.
ContainerPulse is reader-supported. We accept advertising in the form of contextual display units (clearly labelled as Sponsored) and we partner with a small number of editorial sponsors whose links appear in the sidebar and footer. We do not accept payment for inclusion in our directory and we do not write paid carrier reviews. If you find an error in our data, please write to editor@containerpulse.example with a public source and we will correct it within 48 hours.
You can begin exploring the reference from any of the four main hubs:
- Carriers — full directory of 265 ocean container carriers worldwide.
- Trade lanes — 34 port-pair corridor reports.
- Alliances — Gemini, Premier, Ocean Alliance and historical partnerships.
- Container formats — every ISO container type with full dimensions.
