Our China sourcing team has operated in Zhejiang Province since 2012. We know the factories, speak the language, and know how to get the right outcome for importers worldwide.
Our QC team performs material inspections, in-process checks, and final random inspections before goods are packed and shipped. We catch defects while they're still cheap to fix, not after they've reached your warehouse.
You do not need large order volumes to work with us. Whether you are placing your first order or scaling an established supply chain, our team adapts to your needs and budget.
Private label and wholesale sellers sourcing new products or switching suppliers.
First-time importers who want expert guidance without costly trial and error.
Established businesses looking to reduce costs or diversify their supplier base.
Online sellers who need reliable quality and consistent lead times from China.
We coordinate freight, customs clearance, and documentation so your goods move smoothly from the factory in Zhejiang to your destination, whether that's a warehouse, a 3PL, or Amazon FBA.
Quality problems are cheaper to fix during production than after. Our team checks in throughout the manufacturing run, not only at the end, so issues get caught and corrected early rather than discovered in a finished shipment.
"Switching suppliers through Optima cut our unit cost significantly. The factory they found produces better quality than our previous one."
