Include dispute resolution mechanisms in your purchase agreement—preferably arbitration under recognized international trade bodies (such as ICC or your local chamber of commerce). Document all communications and retain records of quality inspections or third-party assessments. If using a B2B platform, leverage built-in dispute resolution services. Escrow payment options can also provide added protection until goods are inspected and accepted.

7. What technical parameters should I prioritize when specifying silicone sheets for industrial use?
   Focus on tensile strength, elongation at break, hardness (Shore A), operating temperature range, thickness, and any required certifications (e.g., flame retardancy, biocompatibility). These characteristics determine suitability for applications from gaskets in oil refineries (requiring chemical and heat resistance) to food processing lines (demanding FDA compliance and hygiene). Share detailed use cases with suppliers and request data sheets outlining precise performance specifications.

8. What strategies can improve supply chain resilience when sourcing silicone sheets internationally?
   Diversify your supplier base to reduce concentration risk—consider both established producers in Asia (notably China) and emerging options in other regions. Negotiate flexible lead times and maintain safety stock in anticipation of shipping disruptions or demand surges. Build collaborative, transparent relationships with suppliers and logistics partners. Regularly review contract terms and stay updated on global shipping trends, tariffs, and regional geopolitical developments to adapt your supply strategy proactively.
