Import Tips
• Verify purity and hydrate form via Certificate of Analysis to confirm classification under 2833.24.00.00 and avoid reclassification as mixtures
• Include SDS and end-use declarations, especially for battery or catalyst applications, to comply with REACH-like regulations and TSCA
• Watch for common pitfalls like mislabeling as ferrous sulfate, which shifts to 2833.21; ensure nickel content >50%
