Import Tips
• Verify purity certificate and CAS number (108-31-6) to confirm classification under maleic acid derivatives
• Ensure proper ventilation and UN-approved packaging for corrosive solid handling during transport
• Check additional U.S. note 3 to section VI for quantitative restrictions on specific polycarboxylic derivatives
