JAKARTA (2026/10/29)

To enter the Muslim market, the halal quality of a product is a key factor every business must consider. Halal is not merely a trend. It is a way of life that Muslims around the world are called to follow, which makes the search for halal products a genuine necessity for them. Moreover, halal does not refer to ingredients alone. It covers the entire production process, from manufacturing to distribution, until the product reaches the consumer’s hands. That is why companies are encouraged to prepare their products in line with the applicable halal standards.

In reality, however, some cases can be confusing. Halal rules may sound simple in theory, but they become far more complex when applied in the field, and the accuracy of certain halal production practices is often questioned. One of them is the practice of using a single factory to produce both halal and non-halal products. This raises an important question: how can halal integrity be maintained when both are made under one roof?

Halal Production in Islam

Islam encourages Muslims to consume what is halal, a term referring to everything that is permitted for consumption. Conversely, Islam instructs its followers to stay away from what is prohibited (haram), the opposite of halal, such as pork and alcohol. Muslims are also encouraged to consume what is wholesome (thayyib), beneficial for both body and soul.

Allah SWT emphasizes this in the Qur’an:

يٰٓاَيُّهَا النَّاسُ كُلُوْا مِمَّا فِى الْاَرْضِ حَلٰلًا طَيِّبًا ۖ وَّلَا تَتَّبِعُوْا خُطُوٰتِ الشَّيْطٰنِ ۗ اِنَّهٗ لَكُمْ عَدُوٌّ مُّبِيْنٌ

“O mankind, eat from whatever is on earth [that is] lawful and good and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy.” (QS. Al-Baqarah: 168)

This principle shapes not only what we consume, but also how products are made and handled. In Islam, the halal status of a product is not determined by its raw materials alone. It also depends on the entire process, from production through distribution. Therefore, every step along the way must be kept free from anything prohibited.

The Seven Stages of Halal Production

In general, the halal production process covers seven stages:

1. Material supply. All materials entering production must be halal, including raw materials, additives (flavorings, colorants, preservatives), and auxiliary materials such as machine lubricants or cleaning agents that come into contact with the product. Halal status is verified through halal certificates or documents tracing the origin of the material. For example, the source of gelatin must be clear, and meat must come from slaughter that complies with Islamic law.
2. Processing. Production must not come into contact with non-halal materials or equipment. This includes mixing, cooking, and equipment washing. If a facility has previously been used for non-halal materials, its equipment must be cleaned using procedures that meet the applicable requirements.
3. Storage. Materials and finished products are stored separately from non-halal materials to prevent cross-contamination, for instance in dedicated warehouses or shelves, clearly marked containers, and separate refrigerators.
4. Packaging. Packaging materials that touch the product must also be free from non-halal elements, such as coatings derived from animal fat or inks that come into contact with the product. The packaging process itself must not be mixed with non-halal products.
5. Distribution. During delivery, halal products must not be transported together with non-halal products without separation that guarantees no contamination. This applies to transit warehouses and transport vehicles.
6. Sales. Halal products must be sold in a way that preserves their status, for example by not displaying or storing them alongside non-halal products. Certified products must also carry the halal label.
7. Serving. This applies to businesses that serve consumers directly, such as restaurants, caterers, and cafes. Tableware, serving areas, and serving methods must be protected from non-halal contamination.

Can Halal and Non-Halal Products Be Made in the Same Factory?

In principle, there is no blanket prohibition on a single factory producing both halal and non-halal products. However, the most important requirement is that the entire halal production process remains free from cross-contamination by non-halal products and their substances. Even minimal contact with non-halal particles can compromise a product’s halal status and make it unfit for the market. For this reason, the entire halal production process must be supported by a thorough inspection process. Specific requirements can also differ by country and by type of business, so they should always be checked against the applicable rules.

To maintain halal integrity, companies producing halal products should pay attention to at least three factors:

1. Location. Areas for producing, processing, storing, packaging, and distributing halal products must be separated from those used for non-halal products.
2. Equipment. All equipment used in halal production must be separate from equipment used for non-halal products, and kept free from impurities (najis) and prohibited substances.
3. People. Everyone involved in the production process must be free from contamination by prohibited substances and have adequate knowledge of how to separate halal from non-halal.

Why Separate Halal and Non-Halal Production?

1. Avoiding najis (impurities) in products

Islam teaches the consumption of what is halal and free from najis. The challenge is that removing najis requires specific and strict cleaning methods. In some cases, the cleaning must be repeated several times and requires specific materials, such as soil. Factories run at high speed, so cleaning is often rushed and the cleanliness of equipment cannot be guaranteed.

2. Preventing cross-contamination

Even when halal and non-halal products are not mixed, indirect contamination can still occur if they are not properly separated. Non-halal particles can be transferred through several pathways, such as mechanical residue, aerosolization, lubricants, and cleaning acids. This can seriously contaminate halal products.

3. Preventing istihalah (transformation of substances)

When contamination occurs, whether direct or indirect, non-halal particles may be drawn into halal products, altering their composition, a process discussed in Islamic jurisprudence as istihalah. A contaminated halal product may look unchanged to the naked eye in color, taste, or aroma, yet it no longer meets halal standards.

4. Protecting halal certification integrity

A product must comply with the halal standards of its destination country if it is to be produced for and imported into that halal market. Halal production sites must therefore be recognized by the halal certification body of the destination country. Each certification body has its own standards, and shared facilities can weaken the halal assessment, while separate facilities strengthen it.

5. Maintaining consumer trust

Muslim consumers care deeply about the halal quality of what they consume, and the production process is an important consideration for them. Guaranteed segregation and halal assurance build consumer confidence and loyalty.

How to Separate Halal and Non-Halal Production?

1. Separate the physical areas. Create clearly marked halal and non-halal zones, divided by barriers and clear signage. Each country has different standards on this. For example, in Indonesia, halal slaughterhouses must be separated from non-halal ones by a wall at least 3 meters high.
2. Use separate equipment. Halal and non-halal equipment must never be used interchangeably.
3. Use separate storage. Keep halal and non-halal products in separate warehouses and chillers.
4. Separate distribution. Halal products must not be mixed with non-halal products during transport.

Recommendation: schedule production at different times. Running halal and non-halal production at separate times, and never at the same time, reduces the risk of overlap between the two lines. It also allows time for thorough cleaning and inspection between production runs, which further helps protect halal integrity.

It should be underlined that the rules on separating halal and non-halal products differ from country to country. Businesses are therefore advised to pay close attention to the halal regulations of their destination country. It is also advisable to discuss these requirements with a halal consulting institution in the country of origin, as such institutions can often assist with export and import processes as well.
