While TME offers several advantages, there are also limitations and considerations: 1. Limited Duration: The exemption is typically valid for only one year, which may not be sufficient for comprehensive market analysis. 2. Volume Restrictions: The quantity of the chemical substance that can be produced or imported is capped, limiting the scope of market testing. 3. Regulatory Burden: Companies must comply with detailed reporting and monitoring requirements, which can be time-consuming and costly. 4. Public Perception: The introduction of new chemical substances, even on a limited scale, may raise concerns among consumers and advocacy groups about safety and environmental impact.
