The tariff environment in 2026 has fundamentally changed how electronics OEMs approach manufacturing location decisions. What was once a relatively stable cost-optimization exercise has become an ongoing risk management challenge, where the wrong factory location can erode margins, delay market access, or strand inventory overnight. OEMs are no longer just asking “where is cheapest?” but “where is safest, most flexible, and most defensible against policy change?”
TL;DR
- Tariff volatility in 2026 is forcing OEMs to treat manufacturing geography as a strategic variable, not a fixed cost decision.
- Single-country production concentration is now a recognized supply chain liability.
- Mexico, Malaysia, and the UK have each gained relevance as complementary manufacturing nodes for tariff mitigation.
- Transferable, standardized production processes are the operational foundation that makes geographic flexibility real rather than theoretical.
- Early design decisions, particularly DFM and supply chain architecture, determine whether a production transfer is feasible or prohibitively costly.

Why Is Tariff Volatility Having Such a Large Impact on OEM Manufacturing Decisions?
Tariff volatility creates a specific kind of operational problem: it reprices production costs without warning and without regard for existing contracts, tooling investments, or supplier relationships. For electronics OEMs, where margins are already tight and bill-of-materials costs are carefully managed, a sudden duty increase on finished goods or key components can wipe out the economic rationale for a given production site almost immediately.
What makes 2026 particularly challenging is the combination of:
- Unpredictable policy timelines: Tariff changes are arriving faster than typical product planning cycles, making it difficult to model landed costs with confidence.
- Cascading effects on component sourcing: Duties on finished goods often interact with separate tariff structures on raw materials and sub-assemblies, compounding the cost impact.
- Customer pressure from downstream: OEM customers facing their own tariff exposure are pushing back on pricing, compressing the margin buffer that would otherwise absorb duty increases.
The result is that manufacturing location is no longer a decision made once at product launch. It needs to be revisited as a live strategic variable.
What Manufacturing Geographies Are OEMs Moving Toward, and Why?
No single geography solves the tariff problem universally. The practical answer for most OEMs is a multi-site strategy that distributes risk across regions with different trade relationships.
| Geography | Key Tariff Advantage | Practical Consideration |
|---|---|---|
| Mexico | USMCA preferential access to North America | Requires compliance with rules of origin; suited to automotive and industrial |
| Malaysia | ASEAN trade frameworks, favourable duty treatment | Strong for electronics; growing aerospace and precision manufacturing |
| UK | Access to certain EU and Commonwealth trade agreements | Higher cost base; best suited to low-volume, high-mix, or NPI |
| China | Established supply chain depth and vertical integration | Facing elevated tariff exposure for US-bound and EU-bound goods |
The shift is not about abandoning China entirely. For many product categories, the component supply ecosystem, production density, and cost structure in China remain difficult to replicate. The more realistic approach is using China for specific elements of the build while routing final assembly or certain product variants through alternative sites.
How Does Geographic Flexibility Actually Work in Practice?
The gap between “we could move production” and “we can move production” comes down to process standardization and design readiness.
Manufacturing a product in two or more locations simultaneously, or transferring a program from one site to another, requires:
- Standardized equipment and process parameters across sites so that the same build quality is reproducible without a full re-qualification program.
- DFM-aware design from the start, so that the product is not tuned to one factory’s specific tooling or component sourcing. A design that is only manufacturable in one configuration in one location is inherently fragile.
- Component sourcing that is geographically diversified so that a site transfer does not immediately run into a localized supply constraint.
This is where DFX disciplines, specifically DFM (Design for Manufacturability), DFA (Design for Assembly), and DFT (Design for Test), become directly relevant to tariff resilience. Products designed with DFX principles from the start are materially easier to transfer, qualify in a new location, and scale in a different region.
OEMs that invested in DFX early are executing production moves in weeks. Those that did not are discovering that their product’s manufacturability is tightly coupled to one site, one set of suppliers, and one process configuration. Unwinding that takes months and introduces real quality risk.
What Should OEMs Prioritise When Evaluating a Manufacturing Location Change?
A structured evaluation should address the following in order:
- Rules of origin compliance: Does the alternative manufacturing location actually qualify finished goods for the preferred tariff treatment? This requires a detailed review of value-add thresholds and component sourcing, not just assembly location.
- Process transferability: Can the current product be manufactured to the same quality standard at the target site? What re-qualification is required?
- Component supply access: Are the critical components available through qualified suppliers within a reasonable logistics radius of the new site?
- NPI and transfer lead time: What is the realistic timeline from decision to volume production? Does this align with the tariff exposure window?
- Total landed cost modeling: Tariff savings must be weighed against tooling duplication, logistics changes, qualification costs, and potential yield differences during ramp.
- Long-term defensibility: Is the target geography likely to remain tariff-favourable over the product’s lifecycle, or is it a short-term arbitrage that may close?
Rushing through any of these steps tends to produce a transfer that solves the tariff problem while creating a quality or supply chain problem of equivalent severity.
Is Dual-Site Manufacturing a Realistic Strategy for Mid-Size OEMs?
For high-volume commodity products, dual-site manufacturing has been standard practice in automotive and aerospace for years. The business case is straightforward: the cost of maintaining a parallel production capability is justified by supply continuity and the ability to rebalance production in response to tariff or logistics changes.
For mid-size OEMs producing more complex, lower-volume electronics, the economics are tighter but increasingly viable because:
- Standardized processes reduce the overhead of qualifying and maintaining a second site.
- IoT and connected products often serve multiple regional markets that already justify regional production footprints.
- The tariff risk premium that OEMs are now pricing into single-site production strategies is, for many programs, larger than the cost of a second qualified site.
The entry point is usually not full parallel production but a staged approach: one primary site with a secondary site qualified and ready to receive volume if needed.
Season Group’s Position Within This Shift
Season Group operates manufacturing sites in China, Malaysia, Mexico, and the UK, each with different regulatory access, certification scope, and production capabilities. The Dongguan facility handles high-volume vertically integrated production; Reynosa carries IATF-TS16949 certification for automotive-grade work; Penang supports aerospace and precision manufacturing with AS9100D coverage; and Havant in the UK handles quick-turn NPI and low-volume complex builds.
Critically, production processes are standardized across sites, which means a program developed in one location can be transferred or mirrored in another without starting from scratch. When combined with DFX-integrated design services, this makes geographic production flexibility an operational reality rather than a theoretical option for customers navigating tariff exposure.
Frequently Asked Questions
Can moving final assembly to a new country eliminate tariff exposure?
Not automatically. Rules of origin requirements specify minimum levels of local value-add. Simply shipping components to a different country for final assembly may not qualify for preferential tariff treatment and can attract scrutiny for tariff circumvention. A proper rules of origin analysis is essential before committing to a site transfer.
How long does a production transfer typically take?
Transfer timelines vary significantly based on product complexity, tooling requirements, and qualification scope. Products with strong DFM characteristics and standardized processes transfer faster. A rough guide is that a well-prepared transfer takes several months from decision to qualified volume production; poorly prepared transfers can take considerably longer.
Does tariff mitigation justify the cost of setting up a new manufacturing site?
It depends on volume, margin, and product lifecycle length. For high-volume programs with long lifecycles, the math often works. For shorter runs, the more practical route is accessing an existing qualified site through a manufacturing partner rather than setting up independently.
What is the risk of tariff conditions changing again after we relocate production?
It is real and should be modeled. The answer is not to avoid relocation but to choose locations with broadly stable or improving trade relationships and to build in process transferability so that a further adjustment, if needed, is manageable.
What role does DFM play in tariff resilience?
DFM directly affects how easily a product can be manufactured across multiple sites. A product designed with DFM principles uses standardized components, minimizes site-specific process dependencies, and supports qualification in new environments with less rework. This is the engineering foundation of geographic flexibility.
Should OEMs redesign products specifically to qualify for regional tariff treatment?
In some cases, yes. Value engineering a product to increase local content at a target site can shift its tariff classification. This is not a trivial exercise but can be justified when the tariff delta is large and the product has a multi-year runway.
What certifications matter when selecting an alternative manufacturing site?
Relevant certifications depend on the product and end market. ISO 9001 is a baseline. Automotive programs require IATF-TS16949. Aerospace requires AS9100. These certifications take significant time to obtain and maintain, so working with a partner that already holds them at the target site avoids a substantial qualification delay.
