Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If misclassified purely by metal salt nature
Other metal salts fall in Chapter 28, but Chapter 29 note 3(C) subordinates to organic parent compound heading.
If when sold as complete water-soluble herbicide formulation
Formulated pesticide products containing Asulam salts classify as herbicides under 3808 regardless of active ingredient form.

Import Tips & Compliance
• 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
