Multi-sourcing for BCP of Cable Noise Suppression Ferrite Cores | Balancing Equivalent Quality, Stable Supply, and Cost Reduction

Quality variation and supply anxiety due to dependency on a single supplier—by multi-sourcing ferrite cores for cable noise suppression, we achieved a stable supply and cost reduction simultaneously while ensuring equivalent quality. This is a standard scheme in fields where demand is growing due to the EV shift and 5G adoption.This solution is tailored for companies facing challenges in the stable procurement of EMC and noise countermeasure components, such as electric wire manufacturers, air conditioner manufacturers, and automotive equipment manufacturers. Simultaneous Challenges of "Defects/Complaints & BCP" Surface in Cable Noise Countermeasures For cable noise suppression ferrite cores, responding to defects/complaints and addressing BCP (multi-sourcing) were requested simultaneously.Dependency on a single supplier reached its limit in terms of both quality variation and risk.● Situations where it surfaces: The defect and complaint response phase.● Main impacts: Frequent complaints, production line stoppages, and the requirement to balance both quality stability and cost competitiveness. Why Dependency on a Single Supplier is Risky: Quality Variation and Prolonged Lead Times Procurement and supply chain factors (supply anxiety, lead times). Dependency on a single supplier.● Specific evidence/basis: Physical property comparison of existing materials, defect sample verification. Countermeasures Attempted So Far and Their Limitations Requesting quality improvements from the single supplier (reached its limit), and abruptly searching for alternative sources (unstable).Based on these limitations, we adopted the following approach as a more radical and fundamental solution. Solution Approach: Developing New Overseas Manufacturers × Parallel Supply Across 3 Sites × Iterative Prototype Evaluation By developing new products from overseas manufacturers and coordinating across 3 sites, we achieved both equivalent quality and stable supply, while also reducing costs. STEP. 01 Developing Overseas Suppliers Sourced ferrite cores with equivalent physical properties STEP. 02 Multi-Site Coordination Parallel supply across China, Thailand, and Vietnam STEP. 03 Iterative Prototyping and Evaluation Confirmation of equivalent quality Fuji Chemi Trading's Supply Network: Headquarters × Shanghai × Thailand × Vietnam This solution is made possible through the division of roles among multiple sites.・Headquarters / Domestic Sales: Customer window and quality control・Shanghai / Thailand / Vietnam: Supplier coordination, local customs clearance, and inventory● Supply Network: Multi-source supply / Inter-site flexibility / Local delivery. Results of Implementation Eliminated delivery troubles, stabilized quality, and achieved cost reductions.● KPI Candidates: Reduction in number of complaints / Zero delivery delays / Cost reduction.● Implementation Lead Time: Repeating prototypes and evaluations, then transitioning to mass production. Expected Ripple Effects and Horizontal Rollout The effects of implementing this solution extend beyond solving the primary challenge. Please also leverage this as material for internal proposals and presentations to executive management.・Rollout to general EMC countermeasure components (common mode chokes, shielding tapes, gaskets)・Cross-industry expansion from white goods to automotive EMC countermeasures・Perfect fit for the sharp increase in noise countermeasure demand driven by the EV shift・Creation of BCP content under the theme of "breaking away from single-supplier dependency" Difference from Competitors: Why Fuji Chemi Trading is Chosen Domestic independent trading companies tend to lag behind in implementing overseas multi-sourcing. Fuji Chemi can handle parallel procurement across 3 sites in China, Thailand, and Vietnam, lowering costs while ensuring equivalent quality.

We ensure equivalent quality by repeating physical property comparisons and prototype evaluations for each manufacturer's product before proceeding with parallel supply. Is it possible to propose general EMC countermeasure components? Yes, we can propose general EMC countermeasure components, including common mode chokes, shielding tapes, and gaskets. Is it possible to expand into the EV and automotive sectors? Yes, we can support the growing demand for noise countermeasures driven by the EV shift. We also have a proven track record in automotive EMC countermeasures. Is it possible to use your services in combination with existing domestic suppliers? Yes, it is possible. By using a dual-sourcing scheme that combines domestic and overseas products, you can also leverage it as a bargaining chip for price negotiations. What is the extent of the cost reduction? Although it depends on the specific project, there are many cases where cost reductions can be expected by strengthening your bargaining power through multi-sourcing.
