Established in 2012 and headquartered in Kunming, China, Yunnan Duo'anxin Trading Co., Ltd. is a one-stop supplier of labor protection products, power tools, and traffic safety equipment for large-scale projects.

Duo'anxin was founded in 2012 on a simple conviction: project buyers deserve a supply partner they can rely on. What began as a focused supplier of traffic and labor-protection products in Kunming has grown into a complete one-stop sourcing operation — connecting engineering contractors, distributors, and government projects with the essentials their sites run on.

Today, with direct access to manufacturing sources, our own warehouse, and a team that understands the pressure of project deadlines, we supply complete orders — not just products.

To make project sourcing simple, transparent, and reliable — one complete order at a time.

To be the supply partner that global project buyers trust first — and recommend without hesitation.

Quality First — every order checked against your specification before it ships.

Integrity in Every Deal — honest sourcing, honest quotes, honest timelines.

Speed with Discipline — fast response, without shortcuts on quality.

Long-Term Partnership — we succeed when your projects do.

Serving project buyers at home and abroad with complete orders across PPE, power tools, and traffic safety.

Started as a focused supplier of traffic and labor-protection products to regional engineering projects.

Added power tools and a full PPE line, and built direct partnerships with manufacturing sources.

Established a 1,000+ m² warehouse to guarantee ready stock and fast dispatch.

We don't resell through layers of traders. Duo'anxin works directly with manufacturing sources across all three product categories — which means better cost control, clearer quality accountability, and the flexibility to match your specification, from standard catalog items to project-specific requirements. For bulk buyers, we can also arrange private-label and specification-matched production through our factory partners.

Direct partnerships across our product lines, so we match the right source to your specification and budget.

Source-level pricing, passed on to you.

Materials, standards, sizing, and branding aligned to your requirements.

Your requirements are confirmed in writing before anything is produced or picked.

Factory output is checked against the approved specification.

Every order is verified again before it leaves our warehouse.

Certificates and test reports supplied where required.

Every order passes specification review before production begins, and inspection before dispatch. For regulated markets, we support the certification and testing documentation your compliance team requires.
