Request breakdowns for unit price, shipping, insurance, and optional add-ons (such as color matching), and benchmark multiple suppliers to negotiate effectively.

8. Are there common pitfalls or best practices for international B2B buyers to ensure supply chain resilience with plastic materials?
   Mitigate supply risks by diversifying your supplier base across different regions and maintaining safety stock, especially if you operate in markets with slower customs or variable logistics (like sub-Saharan Africa or remote regions in South America). Implement periodic supplier evaluations and monitor regulatory changes in source and destination countries. Build strong relationships with key suppliers and freight partners. Proactively plan for currency volatility and global disruptions (e.g., port delays, raw material shortages) by negotiating flexible contracts or buffer lead times.
