Import Tips
• Submit detailed impurity profile in CoA; impurities <5% don't disqualify from chemically defined status
• Label containers with GHS pictograms for skin irritant and flammable properties to prevent delays
• Avoid common pitfall of declaring as 'guaiacol derivative' - specify exact 4-ethylguaiacol nomenclature
