Our Partners
At Celestix, we design and manufacture custom wiring harnesses built specifically for end-use in China—whether for appliances, vehicles, energy systems, or industrial automation. We don’t outsource production to China. Instead, we serve global OEMs and integrators who require high-performance harnesses shipped into China for final assembly, distribution, or system integration.
This page highlights our capabilities as a contract manufacturer of wiring harnesses engineered for the Chinese market, trusted by technical buyers, program managers, and engineering leads worldwide.
Your product may be assembled in China—but your harnesses deserve global-grade quality, consistency, and engineering input. Here’s what Celestix delivers:
Application-specific design for China-bound white goods, EV platforms, HVACs, energy storage, robotics, and industrial systems
Compliance with regional expectations: CN CCC, CE, RoHS, REACH, and customized labeling/packaging for Chinese distribution
Zero-defect manufacturing with serialized testing, FAI/PPAP documentation, and continuity + hi-pot + pull force validation
Rapid prototyping and scalable production, all built in-house under ISO-certified systems
Fluent communication and engineering collaboration, no lost-in-translation moments
Total supply chain integration, so your parts arrive exactly when and where you need them
If you build for China but want a wiring partner with global control and reliability, you’re in the right place.
Our customers typically need China-specific wire harness builds for:
OEM white goods shipped to Chinese retail markets
Automation systems installed in Chinese manufacturing plants
Renewable energy systems integrated by Chinese EPCs
High-speed EV assemblies entering China through local partners
Exported industrial machinery sold into China
Telecom infrastructure manufactured in Europe and integrated by Chinese contractors
Battery management systems supplied to China-based tech ecosystems
Agricultural equipment for distribution to Chinese rural development markets
In each case, we provide not only the product but also full engineering support, documentation, packaging, and certification compliance to meet the needs of Chinese integration.
Unlike basic offshore suppliers, we build every harness with a mindset of:
We act as a technical extension of your team, not just a supplier. Whether you need structured harnesses for EV powertrains or flexible ribbon cables for appliance panels—we bring precision and scalability to every build.
Our wire harnesses meet or exceed:
ISO 9001 and IATF 16949 for automotive-grade builds
UL and CE standards for electrical safety
RoHS/REACH for environmental compliance
CN CCC support when packaging for direct China integration
Custom China-ready labeling (including barcode, QR, or spec-driven formats)
Documentation packages that include drawings, inspection sheets, electrical test data, and first article reports
You get a clean, export-ready, reliable harness—no repackaging, relabeling, or rework required.
When you partner with us, you gain:
In-house engineering to support China-specific project specs
Controlled production for quality, traceability, and fast iterations
Flexible volumes from 10-piece pilots to 10K+ units per month
Fast turnaround on prototypes and custom tooling
Bilingual documentation where needed
Proactive supplier management, including long-lead component forecasts
Cost transparency and forecasting, so your budgets stay accurate and aligned
Single-source accountability—no fragmented handoffs between suppliers
We’re not a broker. We’re a manufacturer that understands how to serve complex, multi-country supply chains—including projects destined for Chinese assembly lines.
No two wire harness projects are alike—especially when the end destination is a dynamic, fast-moving market like China. Regional integration partners often demand tight lead times, specialized labeling, compliance with local safety standards, and even last-minute design iterations. That’s where Celestix stands out.
Our team works closely with you from the earliest design reviews through to post-shipment support.
Need variant-specific drawings for different SKUs going to separate facilities in Guangdong and Suzhou? We do that.
Need your batch serialized, bundled, and labeled to match distributor barcoding systems in the Yangtze River Delta? We’ve done that too.
We don’t just ship parts—we deliver manufacturing clarity and cross-border peace of mind.
Whether you’re launching a smart appliance line for the Chinese market, building solar inverters for a China-based EPC, or producing high-voltage EV harnesses for final assembly in Shenzhen—we can help.
We bring engineering clarity, world-class quality, and region-specific expertise to every engagement. From concept to crate, we manage the full lifecycle of your harness.
Send us your BOM, drawings, and specs. We’ll review your project, offer engineering input, and quote a full production plan—ready to ship into China with confidence.
