Tapioca chips can be Jain, but it depends on how they are prepared:

Jain Dietary Guidelines:

• Jains avoid root vegetables such as potatoes, onions, garlic, carrots, and similar items because uprooting them kills the entire plant and disturbs many microorganisms in the soil.
• Tapioca (cassava) is a root vegetable, so traditionally, it is not allowed in a strict Jain diet.

Conclusion: Tapioca chips are generally not considered Jain, as tapioca is a root vegetable, and consuming it goes against the core Jain principle of non-violence (ahimsa) towards all living beings, including plants and microorganisms in the soil.

If you follow a strict Jain diet, it is best to avoid tapioca chips.
