Import Tips
• Provide Certificate of Analysis (COA) confirming purity and absence of heavy metals to meet FDA or EPA import standards
• Declare exact chemical composition; mislabeling as sodium bisulfite can lead to reclassification under 2832.10
• Check for REACH compliance if transshipping from EU; sulfites may require safety data sheets (SDS)
