The Secret of MSP Tin Export Achievement REPUBLIKA.CO.ID, JAKARTA Achievement of tin exports PT Mitra Stania Prima (MSP) can not be separated from the certification of responsible minerals assurance process (RMAP). This certification is issued by the non-profit Responsible Business Alliance (RBA). Not all tin manufacturers can obtain RMAP certification. The RBA has a number of criteria before issuing RMAP certification. Among other things, the operating profit is purely for the company. Not to be allocated in part to groups that are involved in conflict. Shoe manufacturer NIKE, Inc. is one of many RBA member companies required to investigate the country of origin of tin, tantalum, tungsten, and gold contained in its products.
