US grants TSMC annual license for chip gear imports to China

The US government has granted Taiwan Semiconductor Manufacturing Company (TSMC) an annual license to import American chipmaking equipment to its plant in Nanjing, China.

TSMC, a Taiwan-based chipmaker, said the license allows its Nanjing facility to receive US export-controlled items without separate vendor approvals.

This follows the expiration of earlier exemptions, which required Asian semiconductor firms to seek new export licenses starting in 2026.

TSMC’s Nanjing plant produces 16-nanometre and other mature node chips.

The site accounted for about 2.4% of TSMC’s total revenue in 2024.

🧠 Food for thought

Implications, context, and why it matters.

What the annual license actually permits and prohibits

BIS will license only maintenance of existing fab (semiconductor fabrication plant) operations, while blocking capacity growth and technology upgrades 1. TSMC’s Nanjing site can keep 16nm and 28nm lines near 20,000 wafers per month at 16/12nm (about 40,000 at 28/22nm) 2.
Routine service and replacements stay allowed under U.S. export controls 3 1. TSMC’s annual license lets suppliers ship U.S. export-controlled items to Nanjing without individual vendor licenses 4, which helps meet specialty demand like automotive chips 2.
U.S. policy seeks to keep China-based fabs at least one generation behind peers in Taiwan, the U.S., and Japan 3. That cap holds even with renewals.

Mature-node equipment suppliers face steady demand with capacity constraints

Vendors serving Nanjing can expect steady orders for maintenance, spares, gases, plus chemicals tied to 16nm or 28nm work 3. Revoking the three published Validated End-User authorizations would add over 1,000 export license applications per year, not counting TSMC 1.
Track permits, capex plans, and hiring at the site to spot any push toward capacity creep 1. Any rise in these signals could create openings for suppliers or new friction with regulators.
Suppliers of mature-node tooling should confirm shipments fall under TSMC’s annual license 4. Also plan around broader approval bottlenecks 1 to avoid production hits at the fab.
