The flag is white, horizontally edged black, with a central hook-like design of black and red rectangular sections around a black square. The official website and Nüsse example have the emblem touching the black stripes; a DSR/Stinnes table flag leaves it floating in the white. Stinnes Monsun’s July 2009 funnel has a diamond enclosing HSt over crossed hammers. The modern chartered fleet otherwise appears in its owners’ colours.
The modern liner company traces transatlantic shipping to Hugo Stinnes Schiffahrt in 1907. It operated Caribbean and South African services with chartered tonnage. The source describes successive ownership by Interhansa and Stinnes Holding rather than treating all Stinnes-named concerns as a single continuing company.
