HAS vs IHCS: Which Halal Management System Applies to Your Business?

HAS vs IHCS: Which Halal Management System Applies to Your Business?

Published on 11 September 2026

For businesses preparing for Malaysia Halal Certification, one of the earliest compliance decisions is determining which internal halal management system applies to the business.

Under the Malaysian Halal Management System (MHMS 2020), halal assurance is maintained through two principal internal systems: the Halal Assurance System (HAS) and the Internal Halal Control System (IHCS). HAS is generally used for medium and large industries, while IHCS is generally used for small and micro industries. However, that distinction should not be applied by business size alone. The certification scheme, type of premises and operating model must also be considered.

The practical sequence for a business owner is therefore:

identify the certification scheme → identify the premises or operating model → determine the applicable industry category → identify HAS or IHCS → apply any scheme-specific requirements

HAS and IHCS Both Sit Under MHMS 2020

MHMS 2020 is the parent framework for internal halal management under Malaysia Halal Certification.

It describes MHMS as an integrated management system that organisations develop, implement and maintain in order to manage products and services and preserve halal assurance through either HAS or IHCS.

The framework must also be read together with the applicable Malaysian Standards, Manual Prosedur Pensijilan Halal Malaysia (MPPHM), fatwa, laws, regulations and halal certification circulars.

The competent authority may involve JAKIM, MAIN or JAIN, depending on the applicable certification context.

Where there is ambiguity or a difference in interpretation, MHMS 2020 states that the Bahasa Melayu edition is the authoritative reference.

What Is HAS?

The Halal Assurance System is the more comprehensive internal halal management structure.

MHMS 2020 defines HAS as a set of procedures used by an organisation or company to maintain halal assurance comprehensively.

Its general requirements include:

  • HAS Manual;
  • Halal Policy;
  • Halal Executive;
  • Internal Halal Committee or JKHD;
  • Internal Halal Audit;
  • halal risk control;
  • raw material control;
  • halal training;
  • traceability;
  • HAS Review;
  • laboratory analysis;
  • sertu;
  • documentation and records.

HAS therefore introduces formal governance, dedicated responsibilities, risk management, auditing, training and management review.

Once a company determines that HAS applies, the next task is to build these controls around the actual operation.

What Is IHCS?

The Internal Halal Control System is the general internal halal-control framework used for relevant small and micro industries.

Under MHMS 2020, the general IHCS framework consists of:

  • Halal Policy;
  • raw material control and/or halal risk control;
  • traceability.

IHCS should not be interpreted as “three pieces of paperwork”. These procedures must still operate effectively within the business.

Scheme-specific requirements can also add further controls. A small logistics operator, for example, may need additional halal risk-control procedures for particular logistics activities. A small OEM may need extra controls for customer-supplied materials or customer acceptance.

The correct interpretation is therefore:

IHCS = a more limited general management structure, plus any additional controls required by the certification scheme.

This comparison shows why the question is not whether HAS is “better” than IHCS. The issue is which structure applies to the particular certification category.

Start With the Certification Scheme

MHMS 2020 provides specific HAS and IHCS requirements for several Malaysia Halal Certification schemes, including:

  • food and beverage products;
  • cosmetics;
  • pharmaceuticals;
  • consumer goods;
  • medical devices;
  • food premises;
  • slaughterhouses;
  • logistics;
  • contract manufacturing / OEM.

A business should therefore identify its certification scheme before deciding which internal system to prepare.

Product Manufacturers: HAS or IHCS?

For food and beverage products, cosmetics, pharmaceuticals, consumer goods and medical devices, MHMS 2020 uses industry category to distinguish the applicable system.

Medium and large industries implement HAS comprehensively.

Scheme-specific requirements can also include:

  • R&D representation in JKHD;
  • process-flow documentation for each different processing flow;
  • Halal Executive appointment for each branch premises.

Small and micro industries implement IHCS with:

  • Halal Policy;
  • raw material control;
  • traceability.

For manufacturers, this distinction has practical implications because halal risk can arise during formulation, material selection, receiving, processing, use of processing aids and packaging.

Food-premise classification is one of the clearest examples of why business owners should not assume that every small business automatically uses IHCS.

Food-premise classification is one of the clearest examples of why business owners should not assume that every small business automatically uses IHCS.

  • hotels implement HAS;
  • medium and large catering, food-service and convention central-kitchen operations implement HAS;
  • small and micro businesses in those catering categories implement IHCS;
  • centrally managed cafeterias implement HAS;
  • chain food premises implement HAS;
  • other food premises implement IHCS.

This means a relatively small outlet that forms part of a chain should not automatically assume that IHCS applies merely because the individual outlet is small.

The premises model and management structure matter.

Slaughterhouses Follow a Similar Size-Based Structure

For slaughterhouses:

Medium and large operations

HAS

Additional requirements include involvement of a supervisor and/or slaughterer in JKHD and appointment of a Halal Executive for each branch premises.

Small operations

IHCS

The general requirements include:

  • Halal Policy;
  • halal risk control;
  • traceability.

Because slaughtering involves specific operational and syariah controls, simply knowing that IHCS applies does not remove the need to follow the relevant scheme requirements.

Logistics Requires Scheme-Specific Risk Controls

For logistics:

Medium and large operators

HAS

Their halal risk-control procedures may need to address:

  • warehousing;
  • cross-docking;
  • break bulk;
  • consolidation;
  • third-party contracts;
  • product receiving or selection where relevant.

Small and micro operators

IHCS

However, their IHCS must still include relevant halal risk-control procedures and additional logistics controls where applicable.

The lesson is important:

IHCS does not mean fewer halal risks. It means a different management structure for controlling those risks.

OEM and Contract Manufacturers Need Additional Controls

Contract manufacturing and OEM businesses also follow the HAS/IHCS distinction according to industry category.

Medium and large OEM operations implement HAS and must address additional matters such as:

  • R&D and/or raw-material receiving representation in JKHD;
  • customer acceptance procedures;
  • customer-supplied raw materials;
  • customer lists;
  • raw-material lists;
  • lists of manufactured products;
  • Halal Executive appointment for each branch premises.

Small and micro OEM operations implement IHCS, but additional controls can still apply to customer acceptance and customer-supplied materials.

This is why copying the halal system of another manufacturer can be risky. Two manufacturers may appear similar but have very different compliance requirements if one produces its own products while another manufactures for third-party customers.

Raw Material Control Connects Both Systems

HAS and IHCS differ substantially in management depth, but both depend on effective control over materials entering the business.

A business should be able to determine:

  • what material is being used;
  • who manufactures it;
  • where it comes from;
  • what halal or supporting documentation applies;
  • whether the material has changed;
  • whether the manufacturer or supplier has changed.

Under HAS, MHMS 2020 requires a formal Raw Material Masterlist containing specified information on materials, manufacturers, certification and supporting evidence.

IHCS does not automatically carry the same formal Masterlist requirement, but appropriate raw-material controls remain central where required by the scheme.

Where halal certificates are relied upon as evidence, businesses should also verify their validity and relevant certification information rather than relying solely on a logo printed on packaging.

Traceability Is Required Under Both HAS and IHCS

Traceability is one of the most important common requirements.

A business should be able to identify materials and products throughout relevant stages such as:

purchasing → receiving → storage → processing → finished product → distribution

In practical terms, the company should be able to identify where a material came from and where the resulting finished product went.

MHMS 2020 includes traceability as a requirement under both HAS and IHCS. Companies required to implement HAS must also conduct a mock recall at least once a year.

Avoid Overbuilding and Underbuilding

Preparing the wrong system can create two very different problems.

Overbuilding

A business that falls under IHCS may copy a complex HAS Manual containing committees, audits and procedures that are not part of its applicable general structure.

This can create:

  • unnecessary administrative work;
  • conflicting procedures;
  • records that cannot be maintained;
  • confusion among employees.

Underbuilding

A business that is required to implement HAS may prepare only basic material and traceability documents.

This can leave major gaps such as:

  • no Halal Executive;
  • no JKHD;
  • no internal halal audit;
  • incomplete halal risk controls;
  • no formal HAS Review;
  • insufficient documentation.

The correct approach is to identify the applicable scheme and requirements first.

Build the System Around Your Actual Operation

A HAS or IHCS document copied from another company may still be wrong even when the businesses appear similar.

Certification scheme, premises type, branch structure, manufacturing model and operational risks can change what controls are required.

A better sequence is:

1. Identify the certification scheme
2. Identify the premises or operating model
3. Determine the applicable industry category
4. Confirm HAS or IHCS
5. Identify scheme-specific requirements
6. Build procedures around the actual operation
7. Implement the controls
8. Generate records continuously

This is the practical meaning of halal certification readiness.


Frequently Asked Questions About HAS and IHCS

1. What is the main difference between HAS and IHCS?

HAS is the more comprehensive halal management system, with governance, audits, risk management, training and review requirements. IHCS is a more limited general internal-control framework built around Halal Policy, raw-material and/or halal risk control, and traceability.

2. Is HAS required for every halal certification applicant?

No. The applicable system depends on the certification scheme, premises or operating model and applicable industry category.

3. Is IHCS only for small and micro industries?

Under MHMS 2020, IHCS is generally used for relevant small and micro industries, subject to scheme-specific requirements.

4. Does every medium or large business automatically require HAS?

For certification schemes covered by MHMS 2020, medium and large industries generally implement HAS, but the relevant scheme and premises requirements should still be checked.

5. Can two businesses selling similar products require different systems?

Yes. Their premises type, operating structure, certification scheme or industry category may differ, which can affect whether HAS or IHCS applies.

6. Does a small chain restaurant use IHCS?

Not simply because the individual outlet is small. MHMS 2020 places chain food premises under HAS requirements.

7. Does IHCS mean fewer halal responsibilities?

No. IHCS has a more limited general management structure, but the business must still implement effective halal controls and any additional requirements that apply to its certification scheme.

8. Is a Halal Executive required under IHCS?

A Halal Executive is part of the general HAS structure. It is not listed among the three general IHCS requirements under MHMS 2020.

9. Is traceability required under both systems?

Yes. Traceability is a core requirement under both HAS and IHCS.

10. What is the safest way to determine whether HAS or IHCS applies?

Identify the applicable Malaysia Halal Certification scheme first, then review the premises or operating model and the relevant industry category before applying the general and scheme-specific MHMS 2020 requirements.
