In 2025, businesses are grappling with unprecedented tariff volatility, leading to supply chain disruptions and increased costs. The Trump tariffs represent the largest tax hike for Americans since 1982 and amount to an average tax increase of more than $1,900 per US household this year. A striking 73% of Americans expect a price surge under these tariffs, indicating a potential decrease in consumer demand for manufactured goods. This creates a challenging environment for manufacturers who must navigate rising costs and uncertain demand through strategic inventory management approaches.

Tariffs—taxes imposed on imported goods—increase costs and potentially disrupt supply chains that rely on these imports. The challenge? Traditional inventory management methods like Material Requirements Planning (MRP) struggle to adapt to rapid tariff changes. These systems were designed for stable environments with predictable lead times and costs, making them ill-suited for the volatility introduced by today's tariff landscape.

Enter Kanban: a more agile alternative to conventional inventory management techniques. As a pull-based system that emphasizes flexibility and responsiveness, Kanban is better equipped to handle tariff-related disruptions. In this article, we'll explore why Kanban's pull system provides superior responsiveness and flexibility compared to traditional inventory methods when facing tariff-induced supply chain challenges.

Understanding the Tariff Landscape in 2025

The current tariff situation has dramatically reshaped global trade patterns and supply chain strategies. With tariffs affecting everything from raw materials to finished goods across multiple countries and industries, businesses face a complex web of trade regulations that can change with little notice. This volatility demands resilient and agile supply chains capable of adapting quickly to new tariff realities.

Tariffs disrupt traditional inventory management planning in several critical ways:

Increased Costs

Tariffs directly increase the cost of imported goods and raw materials. For manufacturers using components from affected countries, this can mean sudden price increases of 10-25% on critical inputs. A company producing electronics might see their semiconductor costs jump overnight, forcing difficult decisions about pricing, sourcing alternatives, or absorbing margin impacts.

Lead Time Variability

Beyond direct costs, tariffs introduce significant lead time variability. As goods face additional customs scrutiny or companies scramble to find alternative suppliers, previously reliable delivery schedules become unpredictable. This variability wreaks havoc on production planning and can cascade through the entire supply chain, resulting in stockouts or excess inventory.

Supplier Uncertainty

Tariffs can suddenly make long-standing suppliers economically unviable, forcing businesses to quickly find and qualify new sources. This process typically takes months—time that most manufacturers simply don't have when facing immediate tariff impacts.

The auto industry provides a sobering example of tariff disruption. The 25% tariff on autos and parts has created immediate price increases and supply chain chaos. Industry analysts project these tariffs will cut output by roughly 20,000 cars daily—approximately 30% of US production. This demonstrates the significant impact tariffs can have on production levels in a major industry.

These challenges highlight why traditional inventory strategies are no longer sufficient in a tariff-sensitive environment. Companies must evaluate their supply chains to identify vulnerabilities and opportunities for improvement in their inventory management approaches.

The Limitations of Traditional Inventory Management (MRP) in a Tariff-Sensitive Environment

Material Requirements Planning (MRP) has been the backbone of manufacturing inventory management for decades. Understanding its core principles helps explain why it falters in today's volatile tariff environment:

Push-Based System

MRP operates as a push-based system where production is driven by forecasts, pushing materials through the supply chain regardless of actual demand. This approach works well in stable environments but becomes problematic when tariffs create sudden demand shifts or supply constraints.

Forecast-Driven

MRP relies heavily on accurate forecasts of future demand—a challenging proposition even in stable times. When tariffs introduce additional variables affecting both supply availability and customer demand, these forecasts become increasingly unreliable, leading to inventory imbalances.

Fixed Lead Time Assumptions

Perhaps most problematically, MRP assumes relatively constant and predictable lead times. When tariffs disrupt established supply lines, these assumptions quickly break down, causing the entire planning system to produce inaccurate requirements.

These limitations create several challenges when using MRP in a volatile tariff environment:

• Inability to quickly adjust to changing lead times: When tariffs cause a key component to be delayed at customs or require sourcing from a new supplier with different lead times, MRP systems struggle to adapt. The result? Production delays, expedited shipping costs, and customer disappointment.
• Risk of overstocking due to inaccurate forecasts: If forecasts fail to account for tariff-induced demand changes, MRP systems can lead to overstocking of tariff-affected goods. This results in increased holding costs, potential obsolescence, and tied-up capital that could be better deployed elsewhere.
• Limited flexibility in sourcing decisions: MRP systems typically operate with a fixed set of suppliers and lead times, making it difficult to quickly switch sources when tariffs make existing suppliers less competitive.

Consider this scenario: A furniture manufacturer using MRP receives a sudden notification that tariffs on imported wood will increase by 20% in 30 days. Their system has already generated purchase orders based on standard costs and lead times. By the time they can reconfigure their MRP parameters and generate new plans, they've already committed to purchases that will arrive after the tariff implementation, resulting in higher-than-expected inventory costs and potential pricing challenges with customers who ordered based on pre-tariff quotes.

Kanban: A More Agile Approach to Inventory Management for Tariff Adaptation

While MRP struggles with tariff volatility, Kanban offers a fundamentally different approach to inventory management that provides the agility needed in today's uncertain trade environment.

Core Principles of Kanban

• Pull-Based System: Unlike MRP's push approach, Kanban production is driven by actual customer demand, not just forecasts. Materials move through the supply chain only when needed, creating a natural responsiveness to changing conditions.
• Demand-Driven: Production is signaled only when there's genuine demand, ensuring that inventory levels remain closely aligned with actual customer needs rather than potentially flawed forecasts.
• Visual Signaling: Kanban utilizes cards, boards, or digital displays to represent work items and their status, providing real-time visibility into the production process. This visual management approach makes bottlenecks and opportunities immediately apparent.

Advantages of Kanban in a Tariff-Sensitive Environment

Kanban offers several distinct advantages for companies navigating tariff challenges:

• Responsiveness to changing demand and lead times: When tariffs impact material costs or availability, Kanban's pull system allows for quick adjustments. If a tariff makes a particular component more expensive, the system naturally adjusts production levels based on actual demand rather than continuing to produce based on outdated forecasts.
• Reduced inventory levels and holding costs: By producing only what is needed, Kanban minimizes the risk of holding excess inventory subject to tariffs. This approach optimizes order quantities and reduces the financial impact of tariff-affected inventory.
• Improved visibility into the supply chain: Kanban provides a clear view of the entire production process, enabling businesses to identify and address tariff-related bottlenecks quickly. This visibility extends beyond factory walls to create enhanced supply chain transparency, limiting excess inventory throughout the network.
• Increased flexibility: Kanban systems easily adapt to changes in demand and production requirements. When tariffs force changes in sourcing or lead times, Kanban's visual signals and demand-driven approach enable manufacturers to quickly identify and respond to these changes.

The urgent need for supply chain agility in response to U.S. tariffs has been well-documented in industry publications like Supply Chain Management Review. Kanban directly addresses this need by providing a framework that emphasizes responsiveness and flexibility—exactly what's required in a tariff-volatile environment.

How Kanban Enables Manufacturers to Adapt to Tariffs Effectively

Kanban's advantages translate into specific capabilities that help manufacturers navigate tariff challenges:

Agility in Sourcing

Kanban's demand-driven nature allows manufacturers to quickly switch suppliers if tariffs make certain sources less competitive. The visual nature of Kanban helps track and manage these changes in supplier relationships, making it easier to identify and transition to alternative sources.

For example, when a tariff makes Chinese-sourced components 25% more expensive, a Kanban system can help visualize the impact and facilitate a smoother transition to alternative suppliers from unaffected countries. The system naturally accommodates different lead times and order quantities without requiring extensive reconfiguration.

Reduced Risk of Overstocking

By producing only what is needed, Kanban minimizes the risk of holding large inventories of tariff-affected goods. This reduces the financial impact of tariffs on unsold stock and prevents capital from being tied up in inventory that might face devaluation due to market adjustments following tariff implementation.

Improved Cash Flow

Kanban's focus on minimizing inventory and waste helps improve cash flow, making it easier to absorb tariff costs. Optimized inventory levels and faster production cycles accelerate cash conversion, providing more financial flexibility to address tariff-related challenges or invest in supply chain adaptations.

Enhanced Collaboration

Kanban promotes better communication and collaboration between departments, enabling a more coordinated response to tariff changes. The transparent visualization of the production process encourages cross-functional teamwork, leading to more effective decision-making when facing tariff-related disruptions.

When procurement identifies a potential tariff impact, production, finance, and sales can immediately see the implications through the Kanban system and collaborate on appropriate responses rather than working in silos.

Real-time Visibility

The Kanban board provides a real-time overview of the production process, enabling managers to identify bottlenecks and allocate resources effectively in response to tariff-related disruptions. This visibility allows for informed decisions about production levels, sourcing, and pricing strategies as tariff conditions evolve.
