Import Tips

• Obtain FDA prior notice and food-grade certifications if destined for consumables; USP grade requires additional pharma docs

• Segregate from ammonium carbonates to avoid statistical breakout confusion under 2836.99.50

• Bulk shipments need proper ventilation to prevent caking; declare accurately to avoid penalties for under-valuation
