Introduction: The Threat of Screw Shortage Risks to Manufacturing and the Need for Supply Chain Resilience

In recent years, global supply chain disruptions have severely impacted the manufacturing industry, with approximately 70% of manufacturers experiencing production halts or delays in a 2021 survey. Strengthening supply chain resilience is an urgent imperative.

Screws, indispensable for product assembly, can bring an entire production line to a standstill if even a single unit is missing, leading to losses ranging from tens of millions to hundreds of millions of Japanese Yen per day. Since the pandemic, there have been reports of component procurement costs increasing by an average of 15% due to soaring logistics costs and fluctuating raw material prices.

Manufacturers must redesign robust supply chains to prepare for emergency procurement. This represents a strategic investment at the core of any Business Continuity Plan (BCP). This article will delve into practical supply chain design strategies to minimize screw shortage risks and ensure responsiveness during emergencies.

Ohta Vietnam leverages its extensive experience and local network in Vietnam to strongly support clients in strengthening their screw supply chains. We provide concrete solutions to maximize the potential of local procurement in Vietnam, ensuring stable component supply and cost optimization.

Current State and Risk Factors of Screw Supply Chains: Challenges for Vietnamese Manufacturing

Screw supply chains are exposed to numerous risk factors. External environmental factors such as geopolitical risks, natural disasters, and pandemics have profoundly impacted supplier production capabilities and logistics networks, exposing supply chain vulnerabilities.

Fluctuations in raw material prices also pose a significant challenge. The prices of steel and stainless steel, key raw materials for screws, are highly susceptible to international supply-demand dynamics and exchange rates. Historically, cases of annual price fluctuations of up to 30% have been observed.

Logistics stagnation and soaring transportation costs also exert pressure. In international shipping, port congestion, container shortages, and rising fuel costs have combined to cause sea freight costs to temporarily surge by more than five times during certain periods. Extended procurement lead times and increased costs are inevitable.

Over-reliance on specific suppliers, known as single-source risk, represents the most vulnerable point in a supply chain. Depending on a sole supplier carries the risk of complete production stoppage should issues arise.

Vietnamese manufacturing faces similar challenges. While experiencing rapid growth, it heavily relies on overseas component procurement, with an estimated foreign dependency of approximately 60-70%. High-precision and specialized screws, in particular, are currently imported. This high foreign dependency exacerbates vulnerabilities during supply chain disruptions, making the promotion of local procurement a crucial strategy for risk reduction and resilience.

Fundamental Strategies for Supply Chain Design to Reduce Shortage Risks: A Practical Approach

Strategic design and practical approaches are essential for reducing shortage risks and building a resilient supply chain. This section outlines key strategies that manufacturing decision-makers, procurement managers, and technical personnel should implement.

Implementing Supplier Diversification Strategies

To avoid single-supplier dependency, supplier diversification is fundamental. Implementing “dual sourcing” or “multi-sourcing,” where components are procured from at least two or more suppliers, helps distribute risk in case of issues. One automotive parts manufacturer reduced the risk of supply disruption by approximately 40% through dual-sourcing key components.

Inventory Optimization and Safety Stock Management

Maintaining appropriate inventory levels is crucial for reducing shortage risks and optimizing costs. This requires improving demand forecasting accuracy and setting adequate safety stock. There are cases where securing an average of 30 days’ worth of safety stock reduced shortage risks by 90%. Utilizing Vendor Managed Inventory (VMI) is also effective, leading to reduced inventory management burden and 10-15% inventory cost savings.

Strategic Partnerships for Shorter Procurement Lead Times

Reducing procurement lead times enhances responsiveness to market fluctuations and emergencies. Building long-term strategic partnerships with suppliers is essential, enabling close collaboration for production plan sharing, joint improvements, and rapid decision-making. Nearshoring also contributes; local procurement within Vietnam significantly shortens lead times compared to overseas procurement, improving emergency response capabilities.

Enhanced Information Sharing and Visibility Across the Entire Supply Chain

Real-time information sharing and visibility across the entire supply chain (from raw material suppliers to end-customers) lead to early risk detection and rapid response. For components like screws, centralized monitoring of progress at each stage, inventory levels, and transportation status is crucial. This allows for early identification of bottlenecks and delays, enabling proactive measures. Data shows that companies with enhanced visibility have reduced emergency response times by an average of 25%.

Leveraging Digital Tools (SCM Systems, AI Forecasting)

Digital tools are indispensable for modern supply chain management. Supply Chain Management (SCM) systems integrate procurement, production, inventory, and logistics to support efficient management. AI-powered demand and risk forecasting tools provide more accurate predictions. There are cases where the adoption of digital tools has shortened procurement lead times by 20% and improved forecasting accuracy by 15%, making them powerful assets for resilience. Some companies in Japan are gradually moving toward adopting these digital tools.

Benefits of Local Screw Procurement in Vietnam and Ohta Vietnam’s Role

Vietnam offers significant advantages for local screw procurement due to its geographical advantages and rapidly growing manufacturing ecosystem. Japanese companies can simultaneously achieve supply chain resilience and cost optimization.

Mitigating Geopolitical Risks and Stabilizing the Supply Chain

High dependency on procurement from specific countries or regions directly exposes businesses to geopolitical risks and changes in trade policies. Local procurement in Vietnam diversifies risks and enhances supply chain stability. As part of the “China Plus One” strategy, Vietnam is an attractive option that can significantly reduce the risk of supply disruptions.

Dramatic Reduction in Lead Times and Logistics Cost Savings

Imports from overseas require time for sea freight and customs clearance. Domestic procurement in Vietnam can significantly shorten this process, with data showing an average 30% reduction in lead times. This leads to inventory optimization and reduced storage costs. Furthermore, it can mitigate the risk of fluctuating international shipping costs, potentially leading to logistics cost reductions of up to 25%.

Enhanced Quality Control and Collaboration with Local Suppliers

Local procurement enables close collaboration with suppliers, thereby strengthening quality control. The geographical proximity facilitates factory audits and technical guidance, allowing for swift responses in case of quality issues. Ohta Vietnam has established strong trust with local suppliers and a stringent quality assurance system, ensuring clients can procure Vietnamese-made screws with confidence.

Establishing an Emergency Procurement System and Integrating it into BCP (Business Continuity Plan)

Even with a resilient supply chain, unforeseen circumstances can occur. It is crucial to establish an emergency procurement system and integrate it into your Business Continuity Plan (BCP) to prepare for potential screw shortages.

Pre-securing Emergency Procurement Routes and Creating an Alternative Parts List

To ensure rapid response during emergencies, multiple emergency procurement routes should be secured in advance. This includes building relationships with alternative suppliers and exploring procurement options from different regions. It is also effective to pre-create a list of alternative screw parts and assess the feasibility of switching to standard parts, gaining consensus with the technical department. Setting a goal to reduce emergency procurement time by 50% directly contributes to minimizing production downtime.

Establishing Internal Collaboration (Procurement, Production, Technical Departments) and Role Allocation

During emergencies, all relevant departments—including procurement, production, technical, and quality assurance—must collaborate swiftly and closely. Clearly define each department’s roles and responsibilities, and pre-establish information sharing flows and decision-making processes for emergencies. In the event of a screw shortage, clear role allocation—such as the production department assessing impact, the technical department verifying alternative part suitability, and the procurement department arranging emergency sourcing—minimizes confusion and enables rapid response.

BCP Drills and Regular Reviews

BCP not only requires formulation but also regular drills to verify its effectiveness and make improvements. A 2023 survey revealed that only about 40% of Japanese companies have formulated a BCP, with even fewer conducting drills. Conducting BCP drills at least once a year helps identify emergency response procedures and challenges, making the plan more realistic. Drills should include screw shortage scenarios and simulations that anticipate supply chain disruption risks.
