Import Tips

Verify purity and hydration state (e.g

monohydrate) via certificate of analysis to confirm classification under 2840.30.0010 and avoid reclassification as a mixture

Include Safety Data Sheets (SDS) and ensure proper hazardous materials declaration for oxidizing solids during shipping

Check for REACH or TSCA compliance; common pitfall is failing to declare peroxide content, leading to customs delays
