Import Tips
• Verify purity certificate to confirm anhydrous state and refined borax classification per Chapter 28 notes
• Include Material Safety Data Sheets (MSDS) for borate compounds to comply with hazardous material regulations
• Avoid misclassification as hydrated borax (2840.19), which has different subheading and potential duty rates
