Transforming the Aftermarket Supply Chain
If you are an auto parts importer, a wholesale distributor, or a transmission rebuilding facility facing high local labor costs, limited testing equipment, and capacity bottlenecks, Chongqing Ziptek Co., Ltd. has the ultimate solution. Operating within the 16,000㎡ Ziptek Baoshuigang Factory, our industrial-grade remanufacturing center leverages China’s exclusive bonded zone policies to offer unprecedented efficiency and cost savings for global B2B buyers.
Uncompromising “Plug-and-Play” Quality
In the transmission business, a warranty claim or a return destroys your profit margin. That is why Ziptek has abandoned the inconsistencies of traditional “repairs.” We fully remanufacture.

Every transmission goes through a meticulous, assembly-line process designed to eliminate failure points. We use ultrasonic cleaning to remove micro-debris, and CMMs (Coordinate Measuring Machines) to detect micron-level housing deformations. Furthermore, every unit undergoes 100% mandatory dynamometer testing under simulated road loads to validate shift smoothness and valve body pressure. Backed by SGS and TÜV Rheinland certifications, we ensure every gearbox delivers a flawless, “Plug-and-Play” experience right out of the crate.


Three Flexible Bonded Models to Scale Your Business
Because our factory is located within a bonded zone, processing happens entirely without customs friction or unnecessary tax burdens. We have structured three tailored models to suit your specific operational needs:
- Model 1: Ready Catalog Sales – Eliminate backorders. Tap into our monthly capacity of 3,000 units. We provide instant shipping of popular AT, CVT, DCT, and DSG units to keep your local distribution network fully stocked.
- Model 2: Custom Sourcing & Remanufacturing – Give us your target inventory list. We leverage our extensive Asian core recovery network to source, rebuild, and dyno-test the exact transmissions you need, delivering a complete, high-quality turnkey product.
- Model 3: Overseas Core Processing (Contract Manufacturing) – Send your un-processed cores directly to our bonded factory tax-free. We will utilize our heavy precision machinery and highly skilled technicians to refurbish them and ship them back. It is the smartest way to multiply your production capacity without investing millions in a new physical factory.

Guaranteed Distributor Profit Protection
We believe in growing *with* our B2B partners, not competing against them. To protect the sales channels and profit margins of our loyal distributors, we enforce a strict MOQ of 2 units. This policy allows legitimate repair networks to test our quality and service, while effectively keeping retail B2C customers out of your market space.
Do not let capacity limits or quality inconsistencies hold your business back. Contact our account managers today to discuss which bonded zone processing model will maximize your ROI.
