ISO Certification Company in Indonesia

PT TSI Sertifikasi Internasional (TSI) is a certification body founded in Jakarta in 2013. We audit and certify organizations across Indonesia against international standards and national schemes, helping them prove to customers, regulators and business partners that their management systems work.

Our certification services cover ISO management systems, including ISO 9001 quality management, ISO 14001 environmental management, ISO 45001 occupational health and safety and ISO 37001 anti-bribery management. We also certify food safety systems such as HACCP, information security for IT with ISO/IEC 27001, and sustainability schemes such as ISPO and ISCC for palm oil, biomass and bioenergy supply chains.

Every certification follows a structured, impartial process: application and contract, Stage 1 and Stage 2 audits, a certification decision, and regular surveillance audits. See how it works on our certification process page, browse the service categories below, or contact our team for a quotation.
