No, Tim Tam biscuits from Australia are not halal. They contain 0.05% alcohol and carmine dye (E210), which are not halal. However, Tim Tam biscuits from Indonesia are halal.

answer from Timtam distributor in Netherlands :

Explanation:

1. Australian Tim Tams:
   • Contains 0.05% alcohol.
   • Contains carmine dye (E210), derived from insects, which is not considered halal.
   • Some products may contain cochineal and pork-based gelatin, which are also not halal.
2. Indonesian Tim Tams:
   • Certified halal and do not contain the aforementioned non-halal ingredients.

About Carmine and Cochineal:

• Carmine is a red dye made from crushed insects, specifically cochineal.
• Islamic scholars have differing opinions on the permissibility of eating insects. Most scholars prohibit it, except for Maliki scholars who allow it under specific conditions.
• The permissibility can depend on whether the substance undergoes chemical transformations that change its original nature, potentially making it halal.

Religious Opinion:

• Cochineal Dye: Some scholars argue it can be permissible if it has chemically transformed into a new substance. Others maintain it is haram due to its insect origin.
• Warning Others: If you are certain a product contains non-halal ingredients, it is appropriate to inform others with caution to avoid harm to producers and sellers.
