Do cabotage rules apply to own-account transport, such as a company moving its own goods?

No. EU Regulation 1072/2009 covers road haulage "for hire or reward" — transport provided commercially for a third party in exchange for payment. A company moving its own goods between its own premises in a host country using its own vehicles performs own-account transport, regulated separately under EU Regulation 1073/2009 and not subject to the cabotage rules that apply to commercial hauliers. The distinction matters for businesses operating logistics fleets across Europe — the cabotage limits on this page apply to commercial carriers, not to companies transporting their own inventory between their own locations.
