I am reaching out regarding your OPC Drum offering, as our company is in the process of obtaining Korea's eco-label certification. It's essential for us to ensure that the materials used in our products align with environmental standards and regulations. Could you please confirm whether your OPC Drum contains selenium or any related compounds? This information is crucial for us to proceed with our certification process. Thank you for your attention to this matter; I look forward to your prompt response.
