What is the ruling on re-exporting a product manufactured from customs-exempt raw materials, then selling these raw materials in the local market, and exporting other low-quality products in cooperation with customs officials, and claiming this is evading forbidden taxes?

If the person mentioned imports raw materials exempt from taxes on the condition of re-exporting them as a finished product, and then exports other products instead of the product manufactured from the imported raw materials, this falls under the ruling of smuggling to evade customs duties. It must be noted that if such an action were permissible, the export of low-quality goods must not involve deception or fraud against the buyer.
