• Provide technical data sheets confirming exclusive use in tanning to distinguish from water treatment chemicals
• Ensure packaging labels specify 'tanning preparation' to avoid classification as industrial alum under 2833
• Check for pH specifications as importers often face issues with acidity declarations
