Halal Assurance System (HAS) is introduced by Lembaga Pengkajian Pangan dan Obat-obatan Kosmetika Majelis Ulama Indonesia (LPPOM MUI) since 2005, as a system to assure the halalness of product during validity of MUI Halal Certification.
Every producer must fulfill the needs and rights of consumers, including Muslim consumers. Producing halal products is part of company responsibility to Muslim consumers. In Indonesia, to assure consumers that the products are halal, company needs to have MUI halal certificate. Validity of MUI halal certificate is 2 (two) years. Along that period, company must assure MUI and Muslim consumers that they will consistently maintain the halalness of their products. Therefore, LPPOM MUI requires company to set up a system namely Halal Assurance System (HAS) and documented as a HAS manual.
