Import Tips
• Provide flake size specifications and bulk density data; ensure packaging prevents moisture absorption which destabilizes metaldehyde
• Declare exact tetramer content via NMR or HPLC; impurities must not exceed 2% to maintain classification
• Confirm no added stabilizers beyond transport necessities per Chapter 29 note (f) to avoid reclassification
