Industrial Sourcing from China.
Engineering-aware sourcing, on the ground in Shenzhen.
TongSourcing is a Hong Kong company with a sourcing office in Shenzhen. We help industrial buyers — automation, robotics, machinery, and precision parts — find capable Chinese manufacturers and manage them through delivery.
Factories are selected against your drawings and tolerances, quality is checked before shipment, and problems are resolved on the ground — before they reach you. You buy with the risk managed, not just the price compared.
We support sourcing and supplier management across Guangdong and other locations in China depending on your project.
You stay in control of your business. We manage the risk on the ground.
From Supplier Search to Shipment
From supplier search to shipment, we manage the full sourcing cycle for industrial buyers—with engineering-aware communication at every step.
1. Find Reliable Manufacturers
New Supplier Sourcing
We find reliable Chinese manufacturers for industrial products—matched against your drawings, tolerances, budget, and quality standards. From supplier research and quotation comparison to factory communication, we identify the right sourcing partner for your product.
2. Verify the Supplier
Factory Audit & Supplier Verification
Before you place an order, we can assess your potential supplier’s production capabilities, factory conditions, quality management, certifications, and relevant experience. Our China factory audit service helps you make a more informed sourcing decision and reduce supplier risks.
3. Develop & Produce Your Products
OEM / ODM & Production Management
Whether you need customized parts, private labeling, or full OEM/ODM manufacturing, we coordinate with Chinese factories to turn your drawings and specifications into finished products—and follow up on production schedules and key project details.
4. Control Product Quality
Quality Inspection in China
Checking every order yourself means flying to China each time. We inspect on the ground for you — verifying specifications, quantity, workmanship, packaging, and other quality requirements before shipment. If problems are found, we communicate with the factory and follow up on corrective actions.
5. Follow Up & Coordinate Shipment
Order Follow-up & Shipment Coordination
Already have Chinese suppliers? We follow up on production schedules, coordinate order changes, and handle problems with the factory on your behalf — for a flat fee of USD 280 per month, per order. No hourly billing. We also coordinate packaging, consolidation, and shipping so your goods leave China safely and to specification.
Built for Buyers Who Source Industrial Products from China
Importers & Trading Companies
Buying from China is easy to start and hard to control. We take over the supplier side — sourcing, negotiation, and the day-to-day follow-up — so a bad factory never becomes your problem.
Industrial & Technical Brand Owners
For companies building products around machinery, automation, robotics, or precision parts: we find manufacturers that can actually meet your drawings and tolerances, and manage them through production.
Distributors & Equipment Suppliers
You need reliable supply, repeatable quality, and someone accountable on the ground. We manage your Chinese suppliers so reorders arrive to spec, not to excuses.
Industrial & Automation Buyers
Servo systems, gearboxes, linear motion, encoders, grippers, sensors, CNC-machined parts. We speak the engineering language your factory uses — in English, Japanese, and Russian — and stay within two hours of your supplier.
Companies with Existing Chinese Suppliers
Not ready to change suppliers, but tired of chasing them? We step in as your local eyes and hands — monitoring production, quality, and follow-up while you keep the relationship you already have.
Why Businesses Choose TongSourcing
At TongSourcing, we focus on building long-term partnerships through transparent communication, reliable supplier management, and practical sourcing solutions tailored to your business.
You can work with us either as your sourcing agent (a simple commission on orders we place) or as your trading partner (a flat price per order)—whichever suits your business. We never combine the two on the same order.
Local Presence in Shenzhen
Being based in Shenzhen allows us to visit factories, verify suppliers, monitor production, and resolve issues quickly.
You work with a team that is close to your manufacturers—not thousands of miles away.
Carefully Selected Manufacturers
We don’t simply search supplier directories.
Every manufacturer is evaluated based on production capability, quality standards, communication, and project suitability before we recommend them.
This helps reduce sourcing risks from the beginning.
Transparent Pricing & Communication
We believe trust starts with transparency.
You’ll receive clear quotations, supplier comparisons, production updates, and honest recommendations throughout the entire sourcing process.
We share what you need at the right stage: verified supplier evidence from the start, full supplier details once we work together, and clear cost breakdowns rather than our own supplier files. No hidden costs. No unnecessary surprises.
Dedicated Project Management
One dedicated sourcing specialist follows your project from inquiry to delivery.
No switching between different contacts.
No repeated explanations.
Just one reliable point of communication.
Quality Control Throughout Production
Quality isn’t only checked before shipment.
We monitor production progress, coordinate inspections, and help identify potential issues before they become expensive problems.
Our goal is to help you receive products that meet your agreed specifications.
Clear Scope, Fixed Pricing
Every business is different.
Whether you’re developing a new product, managing multiple suppliers, or scaling production, we tailor the scope to your needs—with clear flat-fee pricing agreed upfront, so you always know what you’ll pay.
