Aerospace composites manufacturing relies on material availability, specification compliance, and predictable lead times. When supply chain disruptions hit, the impact cascades quickly—leading to extended lead times, inflated shipping and handling costs, and the high-stakes risk of production line-down situations.
To maximize procurement efficiency and eliminate supply chain friction, GracoRoberts partnered with an aerospace composites manufacturer to design a customized Vendor Managed Inventory (VMI) and stocking agreement solution. Tailored around high-use products, consumption rates, and strict shelf-life requirements, the program provided measurable cost savings and guaranteed material availability.
The Challenge
An aerospace composites manufacturer was experiencing severe supply chain disruptions that directly threatened manufacturing schedules. Product availability issues and growing lead times created friction across operations, while rising shipping and handling fees drove up total procurement costs.
The manufacturer needed to simplify procurement and protect their facility against costly line-down scenarios. Their goals required addressing several operational challenges simultaneously:
- Supplier Fragmentation: Managing multiple vendors created administrative overhead and inflated logistics costs.
- Lead Time Volatility: Extended and unpredictable delivery windows made scheduling production runs difficult.
- Material Sensitivity: High-use aerospace materials required strict adherence to technical specifications, min/max stocking levels, and defined shelf-life limits.
- Line-Stop Risks: Any delay in core inventory directly threatened active assembly operations.
Off-the-shelf purchasing methods left the manufacturer vulnerable to market fluctuations. They needed a dedicated vendor-managed stocking solution that ensured material availability without burdening their facility with excess inventory.
The Solution
The GracoRoberts sales and sourcing team collaborated directly with the customer’s procurement and operations groups to engineer a customized stocking agreement tailored to their operational footprint.
Rather than applying a standard template, GracoRoberts analyzed the manufacturer's exact consumption patterns, required specifications, and shelf-life constraints to establish optimal min/max stocking parameters for their high-use products.
Dedicated Min/Max Inventory Controls
By defining clear minimum and maximum inventory thresholds based on real consumption data, GracoRoberts guaranteed material availability while protecting shelf-life integrity and avoiding surplus stock.
Consolidated Logistics and Procurement
Consolidating materials under a single, structured agreement reduced administrative touches, lowered shipping and handling fees, and eliminated long lead times for essential composite supplies.
Ongoing Operational Alignment
To maintain long-term supply chain efficiency, regularly scheduled review meetings were established between the customer’s material manager and the GracoRoberts team. These routine touchpoints allowed both teams to adjust stocking levels dynamically as production volumes and material demand evolved.
The Outcome
The customized stocking agreement provided the aerospace manufacturer with a consistent, reliable supply of critical materials, effectively insulating their production facility against supply chain disruptions and eliminating line-down risks.
Beyond immediate risk mitigation, GracoRoberts’ VMI services yielded long-term operational and financial advantages:
- Guaranteed Continuity: High-use products remained in stock and ready for immediate deployment.
- Cost Reduction: Streamlined shipping, handling, and administrative workflows lowered total cost of ownership.
- Proactive Inventory Management: Scheduled review meetings created ongoing transparency, ensuring stocking thresholds kept pace with real-time operational needs.
Key Supply Chain Takeaways for Manufacturers
Several operational insights from this project highlight how tailored VMI and stocking agreements protect complex manufacturing operations:
-
Customization Is Essential for Sensitive Materials
Aerospace materials carry strict specifications and finite shelf lives. A successful stocking agreement must balance consumption velocity against shelf-life windows to keep inventory fresh and compliant.
-
Supplier Consolidation Unlocks Efficiency
Reducing the number of vendor touchpoints minimizes administrative strain, reduces shipping expenses, and simplifies inventory tracking across the enterprise.
-
Active Communication Drives Long-Term Resilience
A stocking agreement requires continuous alignment between plant material managers and distribution partners to ensure inventory levels adapt smoothly to changing production schedules.

Frequently Asked Questions About VMI & Stocking Agreements
What is the difference between VMI and a Stocking Agreement?
A Stocking Agreement is a custom arrangement where a distributor holds dedicated inventory based on agreed min/max levels and specifications. Vendor Managed Inventory (VMI) takes this further by actively managing, tracking, and optimizing the inventory levels, reporting, and replenishment on behalf of the customer.
How do VMI services prevent production line delays?
By maintaining pre-positioned inventory calibrated to a facility’s exact usage rates and lead times, VMI eliminates delays caused by stockouts, extended supplier lead times, or unexpected supply chain bottlenecks.
How are shelf-life and spec-sensitive aerospace materials managed?
GracoRoberts incorporates shelf-life management, temperature-controlled storage, and lot tracking and traceability into custom VMI programs. Min/max thresholds are calibrated so fresh, fully compliant material is delivered without risking expiration in storage.
Can VMI and Stocking Agreements help reduce total procurement costs?
Yes. Consolidating suppliers and utilizing services like consolidated invoicing, reduced shipping & handling, and usage analysis eliminates administrative overhead, lowers freight fees, and prevents costly emergency freight charges.
