Establish clear contractual clauses covering quality standards, inspection procedures, and dispute resolution mechanisms, preferably including arbitration clauses under recognized international laws. Maintain detailed records of communications, samples, and inspection reports to support claims. If issues arise, communicate promptly with evidence and seek amicable resolution through negotiation. Consider engaging third-party inspection agencies at the supplier’s facility or upon arrival to verify quality. If disputes cannot be resolved bilaterally, arbitration in a neutral jurisdiction or international trade courts can be pursued. Building good relationships and transparent communication are key to resolving conflicts efficiently.
