Pro Tips

Always request compound formulation transparency to understand raw material costs and enable alternative sourcing when needed for cost optimization.
Establish pilot-scale trials before full production to validate scale-up and identify potential processing issues that could affect production efficiency.
Negotiate raw material pass-through pricing tied to published indices to protect against resin price volatility while maintaining fair margins.
Maintain relationships with base resin suppliers like Colorado Sun Inc to understand market dynamics and secure alternative supply when compounders face shortages.
Document all compound modifications and processing parameters in a database to facilitate troubleshooting and enable quick replication of successful formulations.
