Import Tips
• Classify by Zener voltage rating in documentation; differentiate from Schottky diodes which may have different treatments
• Provide tolerance specs (e.g
• 5%) to customs for accurate valuation and duty calculation
• Avoid common pitfall of declaring as 'LEDs' due to similar appearance; include reverse breakdown characteristic data
