Why Mainrich?
We Solve Your Biggest Sourcing and Manufacturing Challenges.
Compliance-First Guarantee
We pre-screen every material grade against US/EU Export Control Lists and Dual-Use regulations before you even quote.
If a license is required, we have alternative supply routes or compliant substitutes ready immediately.
→ Zero surprise delays
Capacity
Single-source is risky in 2026. We operate a Multi-Origin Grid across UK, China, and Southeast Asia.
If a geopolitical door closes, we instantly reroute. Your price and lead time stay locked.
→ Supply continuity guaranteed
Cost Competitiveness
No middlemen. No markups. 40-60% below regional distributor pricing. Same ISO certifications, same material grades — direct from source.
Vertically integrated manufacturing means margin stays with you, not a chain of resellers.
→ Manufacturer pricing, guaranteed.
