Import Tips
• Ensure sizing specifications are documented; different granule sizes don't change heading but affect end-use declarations
• Include Material Safety Data Sheets (MSDS) highlighting Class 4.3 dangerous goods status for customs clearance
• Avoid common pitfall of declaring as 'fertilizer additive' which could misroute to Chapter 31
