• Grade & Purity: Higher-grade CMS with enhanced nitrogen yield commands a premium.
  
• Particle Size: Uniform bead sizes improve performance but may cost more.
  
• Order Volume: Bulk purchases significantly reduce per-unit pricing (see our article on How Many Molecular Sieves Should You Use? for sizing tips).
  
• Supplier Location: Local sourcing may lower freight costs.
  

Average Market Price (2025)

• Small-scale orders: $15–$22/kg
  
• Bulk (1 ton+): $12–$18/kg
  

When comparing to 4A molecular sieves, CMS is generally more expensive due to its specialized manufacturing process. However, for nitrogen generation systems, CMS offers a lower total cost of operation due to efficiency gains.
