Additionally, consider using Incoterms to clarify responsibilities for shipping costs, insurance, and risks. Establishing a clear communication plan with your supplier can also help address any potential logistics issues proactively.

8. What steps can I take if I encounter disputes with a supplier?
   If a dispute arises with a supplier, start by addressing the issue directly with them to seek a resolution. Clear documentation of your agreements, communications, and any issues encountered will support your case. If a resolution cannot be reached, consider mediation as a first step before escalating to legal action. Review your contract for any clauses related to dispute resolution, including jurisdiction and applicable law. It may also be beneficial to consult with legal professionals who specialize in international trade to guide you through the process.
