Import Tips
• COA must specify isomer distribution and total alkylbenzene content to validate 2902 classification vs mixtures
• Temperature-controlled shipping (40-50°C) required to prevent solidification; declare flash point (~140°C)
• Avoid common pitfall of declaring as 'detergent feedstock' which may trigger end-use restrictions
