Laboratory leaders are already feeling the effects of US tariffs announced in 2025. Increased duties on imported plastics, reagents, personal protective equipment, and other laboratory supplies have begun to push up procurement costs, affecting cost per test, operating budgets, and purchasing forecasts. Even modest price increases can create significant strain for laboratories that operate under tight margins and fixed reimbursement structures.
Instead of a reactive approach, laboratories can be more systematic by mapping supply vulnerabilities, quantifying financial exposure, strengthening sourcing strategies, and protecting quality during supplier changes.
First step in ensuring laboratory supply chain resilience: Map vulnerabilities
Before laboratories can take action to mitigate supply chain risk, they must first understand where they are exposed. While recent tariff changes have highlighted how dependent many labs are on globally sourced materials, tariffs are just one of many potential stressors. Lab leaders can take the following steps to map where their lab may be vulnerable to supply disruptions:
Identify high-risk categories
It can be overwhelming to consider the implications of a supply chain disruption for every single supply and reagent in the laboratory. Instead, lab leaders should begin by identifying categories of supplies and reagents that are critical to operations and difficult to replace. For example: single-source reagents required for validated methods, proprietary consumables tied to instrument platforms, imported PPE and plastics, instrument components with long lead times, temperature-controlled materials, and custom or specialty chemicals. Other high-risk items include those tied to validated workflows or regulatory submissions. If the lab has to substitute these items, it may need to perform bridging studies or revalidate methods, creating issues with quality and compliance.
Build a critical materials register
Once high-risk materials categories are identified, the next step for lab leaders is to track them systematically through a critical materials register. This is an internal tool that catalogs critical supplies and evaluates them based on several factors. These include the operational impact if the item is unavailable, whether qualified substitutes are available, lead time, whether there are regulatory implications of substitution, and how geographically concentrated the supply is. This approach enables lab leaders to prioritize mitigation strategies.
Look beyond primary vendors
While a domestic distributor may seem like a safe option, they may still rely on raw materials or specialized resins from overseas or single-region manufacturing hubs. When these supply chains are geographically concentrated, disruptive events can impact global distribution. Lab leaders should speak with suppliers about country of origin, manufacturing redundancy, and sub-supplier dependencies.
Quantify operational and financial exposure
After mapping vulnerability, the next step toward meaningful action is to translate supply chain disruption into measurable operational and financial impact. For example, tariffs can result in a percentage increase on imported reagents, plastics, or instrument components that appears minor in isolation. However, in a high-throughput environment, this can significantly impact cost-per-test calculations. This is especially concerning for labs with grant-funded budgets or working under fixed reimbursement rates. Lab leaders can take the following actions to quantify potential operational and financial exposure:
Connect the disruption to cost per test
To determine how sensitive the lab’s cost structure is to fluctuations in consumable prices, lab leaders can ask some key questions. First, what percentage of the cost per test is driven by imported materials? How would an increase (e.g., five to 15 percent) in consumables cost impact margins? Are service contracts or instrument parts subject to tariff exposure?
Account for hidden costs
In addition to impacting price, disruptions can generate secondary expenses that are more difficult to track. These may include expedited shipping fees, overtime caused by workflow instability, temporary process adjustments, and more. These operational expenses can sometimes exceed the direct cost increase.
Consider the cost of revalidation and change
In some cases, the solution to a disruption is to substitute reagents, consumables, or instrument components. This may be the best option; however, lab leaders should be careful to account for the financial impact that extends into quality and compliance. Substitutions may require validation studies, bridging experiments, and documentation updates that require the time of skilled staff and added materials. In regulated labs, these actions must be thoroughly documented as they may receive additional scrutiny under audit.
Advanced Lab Management Certificate

Gain critical skills and IACET-approved CEUs that make a measurable difference.
Evaluate the impact on workflows and service
Laboratory supply chain disruption and instability can have negative impacts on turnaround times, sample backlogs, and client satisfaction. By quantifying both the direct and indirect impacts of supply disruptions, lab leaders can turn supply chain risk into an operational risk management issue, rather than merely a purchasing concern.
Source strategically and segment inventory
Once lab leaders identify where their supply chains are most vulnerable and understand how disruptions translate into operational impact, the next step is to adjust the sourcing strategy. The following are some ways labs can help reduce vulnerability while maintaining operational and financial discipline:
Build redundancy where it matters
Dual sourcing is an effective risk mitigation strategy, especially for critical materials. If method validation permits, lab leaders should pre-qualify secondary suppliers before a disruption occurs. Keep in mind that secondary sources may be more expensive, but this cost may be offset by the operational stability they provide. Diversifying geographically is also important, as heavy reliance on materials from a specific country or region increases the risk of tariffs, regulatory shifts, or transportation disruptions.

Strengthen contract language
Supplier agreements can also impact supply volatility. Specific contract language that addresses price changes, lead-time commitments, or product change notifications can help reduce risk during disruptions. Lab leaders and procurement teams should carefully review agreements for these provisions.
Segment inventory based on risk
Inventory strategy should be based on supply risk rather than cost alone or purchasing habits. A risk-based approach to segmentation enables labs to maintain higher stock for critical materials and those that are difficult to replace without overstocking easily substituted items. For example, lab leaders may want to consider building different levels of stock as follows: large stock of reagents that are single-source or those with long lead times, moderate stock for critical consumables that are multi-sourced, and minimal inventory for readily available materials with stable supply. This approach supports operational continuity but does not require excessive capital or risk expired reagents.
Protect quality during supplier changes
Despite proactive sourcing strategies, labs may still have to substitute materials or source them from alternate suppliers. When this occurs, labs must focus on protecting analytical quality and regulatory compliance. A supply disruption can quickly shift from a procurement challenge to a quality risk if changes are implemented without appropriate oversight. The following practices can help labs maintain quality and audit readiness when supplier substitutions are needed:
Implement structured change management
Structured change management can help to ensure that adjustments do not compromise data integrity. Any change to critical materials should begin with a documented risk assessment. Lab leaders should evaluate whether the new product could impact assay performance, instrument compatibility, or downstream processes. Some substitutions will be straightforward, but in cases where methods have been validated or regulated, additional verification may be needed.
Maintain documentation and traceability
Changing suppliers can trigger updates across many quality documents, such as standard operating procedures, bills of materials, validation files, and supplier qualification records. Maintaining a clear documentation trail demonstrates that substitutions were implemented through appropriate quality processes.
Communicate changes internally
Clear communication ensures that all staff understand procedural updates and can monitor workflows for any anomalies. Operational teams, quality personnel, and lab leadership should all be aligned, and for clinical or client-facing labs, it may be necessary to communicate changes to external stakeholders.
From reactive to resilient
Tariffs and trade policy shifts are reminders that lab supply chains operate in a volatile global environment. Transportation disruptions, geopolitical tensions, raw material shortages, and more can impact the cost and availability of critical materials.
Labs that take a reactive approach may struggle to respond to the latest disruption, while those that treat supply chain management as an operational risk are better positioned to face these disruptions without destabilizing day-to-day operations.
Mapping supply vulnerabilities, quantifying operational exposure, strengthening sourcing strategies, and maintaining quality controls during supplier changes can create a more resilient laboratory infrastructure. Strengthening supply resilience is necessary for maintaining stable, high-quality lab operations.
