The quality management system according to DIN ISO 9002 was introduced in our company back in 1998. In 2002 we passed the "Old" ISO norm and integrated our environmental management system ISO 14001 in addition to ISO 9001: 2000. From the beginning we face the Challenge of the market to reach the highest quality standards for the range of services of Thomas Sluis Int. Speditions GmbH & Co. KG.
