OUR SERVICES
As a full-service product sourcing company, C4 Sourcing helps brands develop, source, and manufacture products overseas from start to finish. We provide complete sourcing solutions, including factory selection, product development, quality assurance, and global logistics.
With more than a decade of experience and trusted manufacturing partners across China, Vietnam, and other global production hubs, we help U.S. companies identify reliable factories, manage production, and ensure consistent quality, cost efficiency, and dependable delivery timelines.
Our team supports a wide range of industries, including tiny homes, construction products, consumer goods, and medical equipment.
Our mission is to make overseas manufacturing simple, transparent, and reliable—giving businesses the confidence to scale production and grow their product lines successfully.
Our product development services help transform product ideas into manufacturing-ready designs.
We work closely with clients to refine materials, manufacturing methods, and design details before production begins. Through prototyping and sample development, we create a final approved prototype — known as our Gold Tag Sample — that defines the exact product specifications for manufacturing.

Material and manufacturing evaluation

Pantone color matching and design refinement

Production-ready product specifications
