Import Tips
• Certificate of analysis must specify 'Asulam sodium salt' with counterion content to confirm Chapter 29 note 3(C)(1) applicability
• Avoid importing with formulation additives; pure salt maintains 2935 classification while formulated products shift to 3808
• REACH registration as Asulam derivative required in EU; US EPA may require separate registration from acid form
