Import Tips & Compliance
• Provide commercial invoice specifying 'sodium formaldehyde sulfoxylate' exact nomenclature to match HTS description precisely
• Comply with TSCA pre-notice if new chemical concerns arise; pitfall is failing to declare reducing properties leading to safety scrutiny
• Confirm 98%+ purity via lab test; lower grades risk classification as mixtures under 3824
