Pro Tips
Partner with experienced traders like Colorado Sun Inc who understand both virgin PET and rPET markets to optimize your procurement strategy and reduce supply risks.
Maintain relationships with 2-3 qualified suppliers to ensure supply security, but avoid excessive supplier fragmentation that reduces purchasing power and increases complexity.
Time major purchases during Q1 and Q4 when seasonal demand is lower and suppliers are more competitive on pricing and terms.
Invest in real-time IV testing equipment to reduce incoming inspection time from 24 hours to 30 minutes, enabling faster supplier feedback and reduced inventory.
Consider long-term contracts with price adjustment mechanisms rather than spot purchases to stabilize costs while maintaining flexibility during market volatility.
