   Logistics for international orders can be complex. Discuss with your supplier whether they handle shipping or if you need to arrange it through a freight forwarder. Ensure that your supplier provides necessary shipping documents, such as commercial invoices and packing lists. Be aware of customs regulations in your country to avoid delays. Additionally, consider insurance for high-value shipments to protect against potential loss or damage during transit.

   If a dispute arises, first attempt to resolve the issue through direct communication with the supplier, documenting all correspondence. If unresolved, refer to the terms outlined in your contract regarding dispute resolution, which may include mediation or arbitration. It’s beneficial to have legal counsel familiar with international trade laws to guide you through the resolution process and protect your interests.
