C11000 Oxygen-Free Copper Rod Export: Vietnamese Cable Manufacturer Boosts Yield by 12%
Published On: July 6, 2026
Case Study: Empowering a Vietnamese Wire and Cable Manufacturer with High-Purity Copper Rod
Client Background
Our client is a mid-sized wire and cable manufacturing factory based in Vietnam, specializing in the production of electrical wires and cables for both domestic and export markets. With continuous production lines running 24/7, the factory requires a stable and reliable supply of high-conductivity oxygen-free copper rod as its primary raw material for wire drawing operations.
Challenges Faced
Before partnering with us, the client encountered three critical issues with their previous copper rod supplier:
| Pain Point | Impact | Root Cause |
|---|---|---|
| Inconsistent Copper Content | Conductivity fluctuations affecting wire quality | Substandard raw material sourcing and inadequate quality control |
| Unstable Delivery Schedule | Frequent production line stoppages and missed deadlines | Poor production planning and lack of rolling stock management |
| Oxidation During Transit | Surface oxidation compromising drawing performance and finish quality | Inadequate packaging with no anti-oxidation measures |
Our Solution
We supplied C11000 oxygen-free copper rod with a guaranteed purity of 99.97% minimum, complemented by three key operational enhancements:
- Anti-Oxidation Vacuum Packaging: Each shipment is sealed in vacuum-grade packaging with desiccant inserts, effectively preventing surface oxidation during ocean freight to Southeast Asia. This ensures the copper rod arrives in pristine condition, ready for immediate drawing without surface preparation.
- Rolling Monthly Production Scheduling: We established a fixed monthly rolling production plan, reserving dedicated capacity for the client. This eliminated the uncertainty of ad-hoc ordering and guaranteed consistent delivery timelines aligned with their production calendar.
- Batch-Level COA Certification: Every shipment is accompanied by a detailed Certificate of Analysis (COA), documenting conductivity, tensile strength, elongation, and purity test results for full batch traceability.
Delivery Terms
- FOB Shanghai Port: Flexible shipping arrangements with the client's nominated forwarder
- CIF Hai Phong Port: Door-to-port convenience with our managed shipping logistics, ensuring seamless customs clearance at the destination
Results Achieved
| Metric | Before | After | Improvement |
|---|---|---|---|
| Production Yield Rate | Baseline | Significantly improved | +8% to +12% |
| Delivery Reliability | Unpredictable | Fixed monthly schedule | 100% on-time |
| Material Quality Consistency | Variable conductivity | Stable 99.97%+ purity | Batch-to-batch uniformity |
| Contract Volume | Spot purchases | Long-term monthly agreement | ~300 tons/month |
Key Takeaways
This case demonstrates how a reliable copper rod supply chain built on product quality, packaging innovation, and delivery discipline can directly impact a manufacturer's bottom line. By addressing the root causes of the client's pain points rather than competing on price alone, we established a long-term strategic partnership valued at approximately 300 metric tons per month.
The client now benefits from uninterrupted production, higher finished product quality, and the confidence of working with a supplier who treats their success as a shared objective.
