  • ID (e.g., passport) or business tax number;
  • Commercial invoice (contact us after purchase);
  • Tip: Contact your local customs in advance!

12、Answer: Duties are determined by your country’s customs based on product type, value, and regulations. To estimate costs:

  • Check your local customs website;
  • Use third-party tools (e.g., Avalara, DutyCalculator).
