Import Tips
• Label as 'Sodium 3-aminobenzenesulfonate' with CAS 121-47-1; include salt confirmation in CoA to match HTS specificity
• Comply with DOT shipping regulations for corrosive solids; use UN-approved drums to prevent leakage-related rejections
• Avoid water-dissolved forms exceeding transport allowances, as chapter note (d) limits solutions to prevent general use classification
