What belongs to the process sector
The sector covers petroleum, petrochemical, specialty-chemical and pharmaceutical plants. Their specialised production units require process construction and maintenance (PCM) expertise, supplied by contractors working with plant owners and engineering/procurement/construction firms. A PCM service business must be an ASPRI corporate member, endorsed as a PCM contractor and on the PCM Controlled List before recruiting foreign PCM workers.

Sources are Malaysia, PRC; NTS India, Sri Lanka, Thailand, Bangladesh, Myanmar, Philippines, Bhutan, Cambodia and Laos; NAS Hong Kong with HKSAR passport, Macau, South Korea and Taiwan. The published application-age minimum/maximum are 18/62, and holders may work until 64, pegged to retirement age. General permit conditions also apply.
Permitted work and 13 skills

SIP, safety and application sequence
Non-Malaysian first-time or returning IPA workers attend SIP before issuance. All process workers take OPSOC before work; workers constructing plants also take CSOC. Find an approved provider through MOM. Apply and obtain IPA first, then buy the non-Malaysian bond, medical insurance and Primary Care Plan.
