The One-Year Leash: Analyzing the New US Export Controls on TSMC Nanjing

The U.S. government has granted TSMC an annual license to import chipmaking tools into its Nanjing, China facility, effectively replacing the previous “indefinite waiver” status that expired on December 31, 2025

The U.S. government has granted TSMC an annual license to import chipmaking tools into its Nanjing, China facility, effectively replacing the previous “indefinite waiver” status that expired on December 31, 2025. While this move secures operational continuity for the next 12 months, it signals a significant tightening of geopolitical control. For conglomerate leaders and founders, the message is clear: The era of long-term certainty in China-based semiconductor manufacturing is over.

The News: A Strategic Reprieve, Not a Green Light

On New Year’s Day, confirmation emerged that Washington has approved a one-year license allowing Taiwan Semiconductor Manufacturing Co. (TSMC) to continue shipping U.S. chipmaking equipment to its fab in Nanjing. This facility, a critical hub for 28nm and 16nm “legacy” nodes, powers everything from automotive microcontrollers to consumer IoT devices.

This decision comes alongside similar annual approvals for South Korean giants Samsung and SK Hynix. However, the shift in mechanism is profound. Until late 2025, the industry operated under the assumption of “Validated End-User” (VEU) status—effectively a permanent green light. By revoking that status and replacing it with an annual review cycle, the U.S. Commerce Department has placed the global chip supply chain on a “short leash.”

The “Annual Review” Trap: Business Impact Analysis

For founders and C-suite leaders, this policy shift introduces a new variable into risk management: Regulatory Volatility.

1. The “Geopolitical Kill Switch”

The move to annual licensing gives Washington a renewable leverage point. Every December, the U.S. administration can now use the renewal as a bargaining chip in broader trade or security negotiations with Beijing.

  • Leader Takeaway: You can no longer treat China-based semiconductor output as “locked in” for your five-year roadmaps. Treat it as “at-risk” inventory that requires a redundant backup plan.

2. Supply Chain Bifurcation Continues

The Nanjing fab primarily produces mature nodes. By granting this license, the U.S. is tacitly acknowledging that severing the supply of legacy chips would hurt U.S. and allied industries (like Detroit automakers) more than it would hurt China.

  • Leader Takeaway: The “Chip War” is becoming more surgical. Advanced AI chips are fenced off; legacy chips are tolerated but monitored. Ensure your product designs distinguish between these supply chains.

3. CapEx Hesitancy

No rational board of directors will approve billions in capital expenditure (CapEx) for facility expansion when the license to operate is only guaranteed for 12 months.

  • Leader Takeaway: Expect stagnation in the capacity growth of foreign-owned fabs in China. If your growth model relies on cheap, abundant legacy chips from these specific facilities, anticipate tighter supply as demand grows but capacity flatlines.

Strategic Action Plan for Founders & Leaders

If your conglomerate relies on hardware, silicon, or global logistics, this development requires immediate attention.

1. Audit Your “Legacy” Exposure Most founders obsess over the latest 3nm chips for AI, but your company likely runs on 28nm chips for power management and display drivers. TSMC Nanjing is a key supplier here.

  • Action: Map your bill of materials (BOM). If >40% of your legacy chips come from China-based fabs (even those owned by TSMC), you are exposed to the annual renewal risk.

2. Diversify into “Friend-Shoring” Hubs TSMC is aggressively expanding in Japan (Kumamoto), Europe (Dresden), and the U.S. (Arizona).

  • Action: Begin qualifying these alternative fabs now. Qualification takes 6–18 months. By the time the next license renewal comes up in late 2026, you should have a “China +1” option ready to flip the switch.

3. Leverage “Inventory Buffers” With the license guaranteed for 2026, the risk of disruption is low for this calendar year.

  • Action: Use this year of stability to build strategic inventory buffers. Do not run “Just-in-Time” (JIT) efficiency models on components sourced from geopolitically sensitive zones.

The Power of “Compliance as a Strategy”

The granting of this license proves that compliance is the new competitive advantage. TSMC, Samsung, and SK Hynix secured these licenses because they opened their books to U.S. regulators and adhered to strict end-use controls.

For your own startup or conglomerate, maintaining a pristine trade compliance record is no longer just a legal necessity—it is the prerequisite for accessing the global supply chain.
