A Halal Assurance System (HAS) is the documented management system a food business uses to keep its products halal consistently, from raw material approval to delivery. In the GCC, the core reference is GSO 2055-1, which sets general requirements for halal food, while GSO 2055-2 sets requirements for the bodies that certify it.
A halal certificate is not a one-off inspection. Certification bodies want evidence that halal integrity is controlled every day, just as HACCP controls food safety. For QA staff across the Gulf, this is a core skill.
This guide covers the standards, HAS elements, control points and a worked example. It does not give religious rulings: on Sharia questions, follow your certification body's guidance.
GSO 2055-1 and GSO 2055-2 explained
The GCC Standardization Organization (GSO) publishes the GSO 2055 series:
| Standard | Who it applies to | What it covers |
|---|---|---|
| GSO 2055-1 | Food businesses producing, handling or trading halal food | General requirements for halal food, including permitted sources, ingredients, processing, storage, transport and labelling |
| GSO 2055-2 | Halal certification bodies | Requirements for bodies that certify halal products, including competence, impartiality and the certification process |
Related GSO standards cover topics such as slaughter, so check which apply to you. Member states adopt GSO standards nationally, and the UAE has adopted the series as UAE.S 2055 within its National Halal System.
Schemes, recognised certification bodies, accreditation and labelling rules change, so confirm current requirements with the relevant UAE federal authority, or the equivalent authority in your country, before certifying.
What a Halal Assurance System covers
Most HAS frameworks share the same building blocks:
- Halal policy: top-management commitment to halal production.
- Halal team: named people from QA, production, purchasing and storage, led by a halal coordinator.
- Raw material approval: every ingredient, additive and processing aid checked, with valid certificates from recognised bodies.
- Critical points for halal integrity: controlled across ingredients, processing, cleaning, storage and transport.
- Traceability: each batch traced to approved materials and forward to customers.
- Training: awareness for all staff, deeper training for the halal team.
- Internal audit and management review: regular checks, corrective action and improvement.
Halal control points: risks, controls and evidence
The term varies between schemes, but the idea is the same: find the points where halal status could be lost, then control and record them.
| Control point | Risk to halal integrity | Typical control | Evidence an auditor expects |
|---|---|---|---|
| Ingredients and additives | Non-halal or unverified source, e.g. gelatine, emulsifiers, enzymes, colours | Approved material list, specifications, valid halal certificates | Approved supplier list, certificate register with expiry dates |
| Processing aids and carriers | Hidden animal-derived or alcohol-based components | Full composition statements from suppliers | Supplier declarations, assessment records |
| Shared lines | Cross-contamination with najs or non-halal materials | Dedicated lines or cleaning as the certification body requires | Cleaning records |
| Storage | Mix-up with non-halal goods | Segregated, labelled storage areas | Store layout, inspection checklists |
| Transport | Mix-up in shared vehicles | Approved transporters, vehicle checks | Vehicle inspection records |
| Slaughter, where applicable | Non-compliant slaughter | Certified slaughterhouse | Slaughter certificates |
| Labelling | Halal logo used outside certified scope | Artwork approval against certified product list | Approved artwork, certificate scope |
Cleaning deserves extra care. Where a line has handled non-halal materials, the certification body decides what cleaning or ritual cleansing is required. Do not set your own rule.
Integrating halal with HACCP and ISO 22000
Many plants run halal within an integrated management system, because the structure overlaps heavily with ISO 22000 and HACCP.
One supplier approval procedure can check food safety and halal status together, and one change control process can flag halal, allergen and safety impact. Keep halal records clearly identifiable, because the halal auditor will ask for them.
Traceability is shared too: see our guide to food traceability and recall readiness.
The role of halal auditors and lead auditors
Halal audits are carried out at two levels. Internal halal auditors check the site's own system, usually as part of the internal audit programme. Certification body auditors assess the site for certification and surveillance, often as a team that combines technical food expertise with a Sharia or Islamic affairs specialist.
A lead auditor plans the audit, leads the team, runs the opening and closing meetings, grades findings and writes the report. Good halal auditors combine food technology knowledge, ISO 19011 audit technique and sound knowledge of halal requirements. Our food safety internal audit checklist is a useful starting point for audit technique.
Worked example: a Sharjah confectionery plant
A confectionery plant in Sharjah makes gummy sweets for the UAE and export markets. Its current gelling agent is gelatine from a certified halal bovine source. The company decides to switch to a pectin-based recipe to suit vegetarian customers and simplify supply.
The halal coordinator treats it as a formal change, not a recipe tweak:
- Change control: the halal team assesses the change alongside food safety and allergen impact.
- Material approval: the pectin supplier provides a specification, composition statement and valid halal certificate from a recognised body, covering standardising agents and processing aids.
- Linked ingredients: the new flavour's carrier is checked with the supplier and certification body.
- Line changeover: the team asks the certification body whether any extra cleaning is needed for the moulding line and starch trays, and records the changeover.
- Halal file update: material list, certificate register, specification and flow diagram are revised.
- Labelling: artwork is approved only once the product is within the certified scope.
- Notification: the certification body is informed, as the certification agreement requires, before product is released with the halal mark.
At the next surveillance audit, the auditor samples the pectin certificate, the change record and the labelling approval, and finds a complete trail.
Common mistakes
- Accepting certificates without checking the issuing body is recognised and the certificate valid
- Forgetting processing aids, carriers and release agents
- Changing a supplier or recipe without telling the halal team or certification body
- Using the halal logo outside the certified scope
- Deciding Sharia questions yourself instead of asking the certification body
Key takeaway: A Halal Assurance System controls halal integrity every day, not just on audit day. Build it on GSO 2055-1, approve every material with recognised certificates, control the points where halal status could be lost and follow your certification body's Sharia guidance.
Frequently Asked Questions
What is GSO 2055-1?
GSO 2055-1 is the GCC standard that sets general requirements for halal food. It covers permitted sources, ingredients, processing, storage, transport and labelling. Food businesses in GCC member states use it as the basis of their Halal Assurance System, and national schemes such as the UAE National Halal System adopt it. Always check you are working to the current version adopted in your country.
What is the difference between GSO 2055-1 and GSO 2055-2?
GSO 2055-1 applies to food businesses and sets the requirements for halal food itself. GSO 2055-2 applies to halal certification bodies and sets requirements for their competence, impartiality and certification process. A food plant implements GSO 2055-1, while the body certifying that plant must meet GSO 2055-2 and the accreditation requirements of the country concerned.
Is halal certification mandatory in the UAE?
It depends on the product and whether you make a halal claim. Certain products, such as meat and poultry, and any product labelled or marketed as halal are generally expected to carry certification from a recognised body. Rules, scope and recognised bodies change, so confirm current requirements with the relevant UAE federal authority before importing, labelling or exporting.
Can a Halal Assurance System be integrated with ISO 22000?
Yes. Both share a management system structure: policy, team, prerequisite programmes, supplier control, traceability, internal audit and management review. Many plants run one integrated system with shared procedures and clearly identified halal records. Integration reduces duplication, but the halal-specific requirements and the certification body's Sharia guidance must still be met in full.
How do I become a halal auditor?
Most halal auditors start with a background in food science, food safety or quality assurance, then gain audit training, halal standards training and supervised audit experience. Certification bodies set their own competence criteria for auditors and lead auditors, so check the requirements of the body you want to work with. Experience in internal auditing within a food plant is a strong foundation.
