Import Tips
• Verify purity and ensure the product qualifies as 'chemically defined' per Chapter 28 Note 1 to avoid reclassification
• Include Safety Data Sheets (SDS) and confirm peroxocarbonate composition via lab analysis for CBP scrutiny
• Watch for common pitfalls like mislabeling as sodium carbonate (2836.20), which has different rates
