   Sustainability impacts include recyclability, environmental footprint, and compliance with regional eco-regulations. PET is often favored for its higher recycling rates and widespread acceptance in circular economy initiatives, especially in Europe and parts of South America. HDPE, while durable, may pose challenges in recycling depending on local infrastructure. Prioritize suppliers committed to eco-friendly manufacturing practices, such as using renewable energy or producing biodegradable variants. Certifications like Green Dot or Cradle to Cradle can also guide responsible sourcing, aligning your supply chain with global sustainability standards and consumer expectations.

8. What steps should I take if I encounter quality issues or disputes with an international supplier?
   Immediately document the issue with detailed photos, test reports, and correspondence. Communicate promptly with the supplier, referencing contractual and quality agreements, to seek corrective action or replacements. If informal resolution fails, invoke dispute resolution clauses—preferably arbitration—to ensure enforceability. Engage legal counsel if necessary to assess breach of contract or compliance violations. Consider involving third-party inspectors or testing labs to verify claims independently. Establishing ongoing quality monitoring and maintaining transparent communication helps prevent recurrence and ensures sustained supply chain integrity.
