Reshoring Cost Analysis: China vs Mexico vs US Landed Cost

A reshoring cost analysis compares the total landed cost of a product, not its factory price: materials, labor, overhead and automation, plus freight, duties, the cost of inventory in transit, and quality and warranty, for each place it could be made. Under the US tariff regime in force in late 2026, a stylized assembled product that costs $53.80 to make in China lands at $84.02 in the United States, against $60.49 from a Mexican plant that qualifies under USMCA and $70.96 from an automated US cell. Manual US assembly, at $92.14, is still the most expensive option. The labor gap, not the tariff, is what reshoring has to beat.

The case that taught many US manufacturers that lesson was a tool plant in Texas. Stanley Black & Decker opened an automated Craftsman plant in Fort Worth in 2020, a project of about $90 million planned for about 500 jobs. It closed with about 175, after the company told the SEC it could not fully ramp production with the new automation, and recorded about $44 million of write-downs in 2023. The plan assumed that automation would close the labor gap. It did not, because the automation never ran at rate.

What goes into total landed cost?

Build the comparison in seven layers, per unit, for each location.

1. Materials and components. Price them where the plant will buy them. US buyers of metal pay prices that sit behind Section 232 duties, which have been 50% on steel and aluminum since 4 June 2025.
2. Labor. Hours per unit times a loaded hourly cost. Hours vary across plants by more than wages do, so measure both.
3. Overhead and automation. Plant overhead per unit, plus the depreciation of any automated cell spread over the year's output.
4. Freight and logistics to the customer.
5. Duties. Charged on the customs value under whichever legal authority applies on the date of entry.
6. Pipeline inventory. Goods in transit or in buffer stock are owned and carry a financing and holding cost, which grows with the length of the pipeline.
7. Quality and warranty. Usually modeled as a share of factory cost, and often higher for distant suppliers.

Then add what the per-unit model leaves out: the one-off cost of moving production, including new tooling, qualifying the product and its suppliers with customers and regulators, scrap and slow output during the ramp, and often paying two plants at once.

A worked landed-cost comparison

Appendix A of The Production Equation works this through for one invented product made at 250,000 units a year. Materials cost $40.00 a unit at world prices and 8% more when bought in the United States. Labor is 1.2 hours at $6.50 in China, 1.2 hours at $9.00 in Mexico, 1.0 hour at $38 for manual US assembly, and 0.35 hours at $42 in an automated US cell that costs $4.5 million, depreciated over seven years. Pipeline inventory carries a cost of 25% a year for ten weeks from China, three from Mexico and one in the United States.

The duty stacks are illustrative, not rates for any real tariff code. Chinese goods pay a 2.5% normal duty, 25% under the 2018–19 Section 301 lists, and 12.5% under the Section 301 regime in force from 24 July 2026. USMCA-qualifying Mexican goods are exempt; non-qualifying Mexican goods pay 2.5% plus Mexico's 10% tier.

Stylized example from Appendix A of The Production Equation; invented numbers and illustrative duty stacks. Excludes one-off moving costs.

Three findings carry over to real decisions. First, the qualifying Mexican plant wins, and the margin over China is large. Second, manual US assembly loses even with the highest tariffs on China in the table, because $38 of US labor against $7.80 in China is a bigger gap than the duty closes. Third, the automated US cell beats China but still not qualifying Mexico. Credible reshoring is usually automation plus a tariff, not a tariff alone.

How sensitive is the answer to tariffs?

Run the Chinese case again under older duty stacks and the picture changes.

Stylized; same assumptions as the table above.

Before 2018, China at $62.87 would have beaten the automated US cell by about $8. The cell pays only because of the tariff layers added since. That is the risk to price into any reshoring plan, because the legal basis of broad US tariffs changed four times in 2025–26. Emergency-powers tariffs imposed in 2025 were struck down by the Supreme Court, 6–3, on 20 February 2026. A 10% global tariff under Section 122 applied from 24 February to 24 July 2026 and expired at its 150-day limit. The Section 301 regime that replaced it has no statutory expiry. A plant that pays only behind a tariff is exposed to whoever next changes it.

How to classify your product before you model it

Duty depends on classification, and in 2026 classification decides which law applies, not just which rate. Section 301 excludes goods covered by Section 232, so an input classified as a metals derivative pays the metals rate instead. The base also changed: from 6 April 2026, metal-containing goods in the relevant annexes pay on their full customs value rather than on their metal content, which can multiply the duty on a machine with a modest amount of steel inside, unless an exclusion or cap applies. The book's section on tariffs, trade and reshoring sets out the sequence.

For Mexico, USMCA qualification is the variable that matters most. The rules of origin turn on content and tariff-shift tests a product either meets or does not. Mexican assembly that relies on Chinese components may not qualify, and Mexico raised its own tariffs from 1 January 2026 on about 1,400 lines from countries without a trade agreement with it, which made Chinese components more expensive for Mexican plants. And at the USMCA review on 1 July 2026, the United States declined to confirm the agreement's 16-year extension, turning qualification into a question asked again each year from 2027.

What do real reshoring decisions look like?

The companies that moved production in 2025–26 did so product by product. Mattel said in May 2025 that about 40% of its production was in China and set a target of less than 15% of US-sold toys from China in 2026 (reported). Stanley Black & Decker, with about 15% of its product mix from China, targeted no Chinese production for the US market by 2026 or early 2027. Both moves are mostly to other low-cost countries, which is trade diversion rather than reshoring.

Large appliances are the clearest case for US production, because they are bulky to ship. GE Appliances, owned by Haier, announced on 13 August 2025 more than $3 billion of investment over five years to move refrigerator, gas-range and water-heater production to the United States from China and Mexico. That is a pledge, not spending. Whirlpool shows the limit of protection: the washer safeguard of 2018 raised washer prices about 12% (economists' estimate, reported), but it also brought Samsung's and LG's plants inside the wall, and the steel in Whirlpool's own washers was taxed under Section 232.

Retaliation can push production the other way. When the EU answered the 2018 metals duties by raising its tariff on US-made motorcycles from 6% to 31%, Harley-Davidson said it would move production for EU customers to its international plants.

What do the data say about reshoring?

Three measures disagree. Announcements count intentions. Import ratios, such as Kearney's Reshoring Index, compare imports from Asian low-cost countries with US output; its edition of 29 April 2026 scored −91, after −115 in 2025, still negative, with US manufacturing imports at a four-year high (reported). Output and construction data show a boom that has passed its peak: manufacturing construction spending reached about $249.8 billion at an annual rate in August 2024 and fell about 32% to about $170.7 billion by August 2026 (Census). Revised data showed about 103,000 manufacturing jobs lost between January 2025 and January 2026 (BLS, reported).

The 2022–24 construction boom was real, but it was concentrated in chips and batteries and driven more by subsidies than by tariffs. The case study on why Intel Foundry is losing money shows the limits of that model.

A checklist for your reshoring decision

Model total landed cost, not piece price, for each location, with pipeline inventory and quality included.

Run the tariff sensitivity. Find the duty level at which each option wins, and ask how likely that level is to last.

Classify first. Section 232 coverage, the annex and the base decide the duty before the rate does.

Test USMCA qualification honestly, including where your components come from.

Price the move itself: tooling, qualification, ramp scrap and two plants running at once. The book's chapter on plants, ramps and capacity shows why the ramp usually decides a plant's value.

Do not treat automation as capability. If the plan depends on an automated cell, budget for a slow ramp and a cell that never reaches its design rate.

The comparison of contract manufacturing vs in-house production covers the related question of whether to own the new plant at all, and the guide to how manufacturing companies make money sets these costs in the wider economics of the factory.

The takeaway

Reshoring turns on a product worth making at the price it will fetch when the tariff changes, which is why the book names "a tariff mistaken for a competitive cost" as one of the industry's recurring traps. In the stylized comparison, a USMCA-qualifying Mexican plant beats China by 28%, an automated US cell beats China by 16% only because of the tariffs added since 2018, and manual US assembly loses to both. Model total landed cost, test it against the tariff disappearing, and treat automation as something to prove rather than assume. The full tariff sequence and the worked example are in Chapter 20 of The Production Equation, available to preview on the book page.
