Rowlinson Timber is moving its distribution centre from the port of Grimsby to inland port complex Groveport Logistics, in Gunness, effective as of 2 January 2014.
Rowlinson imports timber from the Baltic States, Scandinavia, and Russia, into Grimsby.
It said the relocation will offer benefits, such as strong motorway access to all UK destinations for haulage companies, and 60,000 sq m of storage.
