# Nearshoring (US/Mexico) vs. Maintaining China-Based Supply Chains

> The mathematical break-even for onshoring typically occurs between month 36 and 48. While China offers 15-25% lower immediate OpEx, USMCA-region production reduces lead times by 60% and eliminates tariffs. Break-even is achieved when tariffs and logistics volatility exceed 12% of total landed cost, favoring nearshoring for high-value, critical mineral-dependent electronics and automotive components.

## 5-Year Comparison Matrix

| Dimension | USMCA Nearshoring | China-Centric Sourcing | Edge |
|---|---|---|---|
| Lead Time | 3-10 Days | 30-60 Days | Path A |
| Initial Cost | Very High | Very Low | Path B |
| Political Risk | Low (USMCA) | High (Geopolitical) | Path A |
| Unit OpEx | Moderate | Lowest | Path B |

## Non-Linear Plot Twists

- **Trade War Escalation:** US imposes blanket 60% tariffs on all Chinese imports.
- **Taiwan Strait Crisis:** Severe maritime blockade disrupting East Asian shipping lanes.
- **Green Subsidy Boom:** US IRA grants provide massive tax credits for domestic production.

## Frequently Asked Questions

### When is onshoring mathematically the correct choice?
When (var_2 * Annual Volume) > (Annualized CapEx + Labor Delta). For most firms, this happens when tariffs exceed 15% or lead-time costs exceed 10% of GM.

### How does the USMCA impact the cost formula?
It reduces the 'var_2' (tariff) component to 0% for qualifying goods, shifting the cost burden from variable tariffs to fixed regional labor.

### What is the biggest hidden risk of remaining in China?
Critical Mineral Weaponization. If China restricts graphite or lithium, the cost formula for Path B becomes irrelevant as production stops entirely (Infinite Cost).
