Due to the high growth, RINNEN moved to a larger premises in Moers in 1974. In the same year the first two European subsidiaries in Spain and France characterise the international expansion of the company.

The purchase of the first tank containers in the seventies paved the way for intermodal transport - an important step for the company's development. The eighties and nineties are marked by strong expansion: locations in Italy, the Netherlands, Great Britain, Poland, Hungary, Belgium and Leuna are opened and expand the European logistics network of the company. As a result, RINNEN developed into an industry-oriented service company, which in its third generation provides sophisticated logistics services and various service functions in Europe, primarily for the chemical industry. In the future, RINNEN continues to see itself as a family business. The fourth generation is already preparing for their future roles.
