For manufacturers that rely on complex supply chains, sourcing components from overseas can create challenges beyond the quoted price of a part. Long transportation routes, changing lead times, inventory requirements, quality concerns, geopolitical uncertainty, and communication delays can all affect the true cost and reliability of offshore sourcing.
These factors have increased interest in reshoring manufacturing or bringing production and sourcing activities back to the United States. According to the Reshoring Initiative, approximately 287,000 reshoring and foreign direct investment manufacturing jobs were announced in 2023, followed by roughly 244,000 in 2024.
Reshoring does not mean domestic manufacturing is automatically the right choice for every component. Manufacturers still need to compare cost, capacity, quality requirements, tooling, volume, lead times, and supplier capabilities.
What Is Reshoring Manufacturing?
Reshoring manufacturing is the practice of returning production or sourcing previously performed overseas to a company's home country. For a U.S. manufacturer, that could mean moving an owned operation back to the United States or replacing an overseas supplier with a domestic manufacturing partner.
Reshoring differs from nearshoring, which moves production closer to the home market without necessarily bringing it into the same country. Offshoring moves operations or sourcing to a foreign country.
These strategies do not have to be all-or-nothing decisions. A manufacturer may continue working with international suppliers while developing a U.S. source for strategically important parts. Dual sourcing can reduce reliance on a single supplier or geography.
Why Are Manufacturers Reshoring Production?
Manufacturers have long sourced internationally to take advantage of lower labor costs, supplier specialization, or production capacity. However, the lowest quoted component price does not necessarily create the most reliable or cost-effective supply chain.
Port congestion, transportation interruptions, geopolitical changes, shortages, tariffs, and shifts in customer demand have shown how vulnerable complex supply chains can become.
Government incentives have also encouraged domestic manufacturing investment. Programs created through legislation such as the CHIPS and Science Act and Inflation Reduction Act have supported U.S. manufacturing, sourcing, and capital investment.
Still, reshoring is not always quick or simple. A 2024 Bain & Company survey found that 81% of participating CEOs and COOs planned to bring supply chains closer to their primary markets, but only 2% reported having fully completed those plans.
For many manufacturers, reshoring is therefore not about eliminating global sourcing. It can complement nearshoring, regional sourcing, or dual-sourcing strategies while strengthening supply chain resilience.
What Are the Benefits of Reshoring Manufacturing?
The benefits of reshoring manufacturing vary by product and supplier, but several advantages can influence sourcing decisions.
Domestic suppliers can provide shorter and more predictable lead times by eliminating ocean freight and many international logistics steps. Shorter supply lines can also make it easier to respond when production requirements or customer demand change.
Communication may improve as well. Engineers and quality teams can work more directly with suppliers when reviewing drawings, investigating quality concerns, or introducing design changes.
Domestic manufacturing may also provide greater visibility into production and quality processes. For proprietary designs, processes, or tooling, domestic sourcing may strengthen intellectual property protection by reducing the number of international parties and jurisdictions involved.
Reshoring can also reduce exposure to transportation and geopolitical risks. For critical components that can stop an assembly line when unavailable, greater supply certainty may carry significant value.
Reshoring can also support economic activity beyond the manufacturer making the initial investment. Expanded domestic production may create direct manufacturing jobs while increasing demand for machining, tooling, maintenance, logistics, materials, and other supporting services. For manufacturers, that broader supplier ecosystem can become another advantage over time by increasing access to nearby technical expertise and production resources.
Why Total Cost Matters More Than Offshore Piece Price
One of the most important steps when considering reshoring is comparing total cost rather than focusing solely on the supplier's quoted price.
An offshore casting may appear less expensive than a domestic equivalent, but purchase price represents only part of the cost of getting that component into production.
A total cost of ownership analysis may consider:
- international transportation and expedited freight
- tariffs, duties, and related fees
- inventory and safety-stock requirements
- quality problems, scrap, and rework
- supplier audits and travel
- production interruptions
- secondary machining, finishing, and inspection
The importance of each factor varies by application. A stable, high-volume component with a mature overseas supply chain may have very different economics from a critical part with long lead times or significant secondary processing.
Casting buyers should also look beyond the raw casting price. Dimensional tolerances, machining stock, surface condition, consistency, and finishing requirements can influence the cost of the finished component.
A domestic casting with a higher initial price may remain competitive if it reduces machining, inventory, logistics, or rework. Conversely, reshoring may not make economic sense if those benefits are limited.
What Challenges Should Manufacturers Consider Before Reshoring?
Reshoring requires more than finding a U.S. supplier and transferring a purchase order. Manufacturers need to determine whether domestic suppliers have the capacity, equipment, technical capabilities, and workforce to reproduce the part consistently.
Skilled labor can be a significant constraint. Manufacturers continue to compete for machinists, technicians, engineers, and other experienced workers.
Capital requirements can also be substantial. Equipment, automation, tooling, process development, supplier qualification, and training may all be necessary before reshored production reaches full capacity.
Kearney's 2025 Reshoring Index, which measures 2024 manufacturing activity, declined more than 300 basis points after two positive years. The result shows that domestic capacity and execution do not always advance as quickly as reshoring plans.
Tooling is another consideration for cast products. Existing tooling may need to be transferred, repaired, modified, or replaced, and changing casting processes may require new patterns or hard tooling.
Manufacturers also need to plan for supplier qualification. Samples may require dimensional inspection, metallurgical testing, machining trials, assembly verification, or performance testing before production approval.
Transition planning is especially important when the component is already tied to an established production program. Manufacturers may need to build temporary inventory, overlap suppliers, or phase production between sources while the new domestic supplier completes testing and approval. That added cost can be worthwhile if it reduces the risk of an abrupt supply interruption, but it should be included in the reshoring budget from the beginning.
For these reasons, some manufacturers maintain offshore suppliers while adding domestic sources, creating a dual-sourcing strategy that adds redundancy while domestic production is proven.
How Can Domestic Casting Suppliers Support a Reshoring Strategy?
When reshoring an iron casting, manufacturers should evaluate more than whether a domestic foundry can pour the correct material. The transition creates an opportunity to determine whether the existing manufacturing process remains the best fit.
The foundry should evaluate material specifications, geometry, tolerances, draft, cores, surface-finish requirements, machining stock, inspection requirements, volume, and secondary operations. Pattern tooling should also be reviewed to determine whether it can be reused or should be replaced.
Early collaboration between the foundry and customer's engineering team can identify manufacturability issues before production tooling and qualification begin.
Consider the Casting Process, Not Just the Supplier
A reshoring project may also be an opportunity to reconsider the casting process.
Green sand casting can provide attractive economics where looser dimensional requirements and additional machining are acceptable. Investment casting can provide greater precision for applications that require it, but typically at additional cost.
Shell molding occupies another position within that range. In the shell mold casting process, fine resin-coated sand is thermally bonded around a heated pattern to create a rigid mold. For suitable applications, shell molding can provide tighter tolerances, consistent dimensions, minimal draft, near-net-shape features, and a smoother surface than conventional green sand casting.
Those characteristics can matter during reshoring because reducing downstream operations may improve the total-cost comparison. Hiler Industries notes that some shell molded applications can require less machining stock and, in certain cases, eliminate machining operations entirely. Results depend on the individual casting.
Evaluate the Entire Path from Pattern to Finished Part
Supplier evaluation should also extend beyond the mold and pour. Pattern creation, metallurgy, machining, grinding, finishing, coatings, heat treatment, inspection, warehousing, and shipping can all affect how efficiently a reshored component moves through production.
Hiler Industries maintains an in-house pattern shop and tooling maintenance operation and supports its casting operations with centralized finishing capabilities and an industrial CNC machine shop.
Coordinating these capabilities through one supplier can simplify communication and provide greater visibility from tooling through the finished component.
