SAMR Merger Control in China — Filing Basics

China’s antitrust merger-control regime can apply to onshore and some offshore deals that affect the China market. Missing a required filing is a classic cross-border M&A risk.

Definition

Merger control (concentration of undertakings) review is administered primarily by SAMR. When a transaction qualifies as a concentration and turnover thresholds are met, parties generally must file and wait for clearance before implementing the deal.

At a glance

  • Equity acquisitions, mergers, and certain joint ventures can all be concentrations
  • Turnover thresholds are technical; use counsel to model group figures correctly
  • “Gun-jumping” (closing or integrating early) attracts fines and remedial orders
  • Remedies or prohibition are possible in competitive markets
  • Separate from NSR and foreign-investment market access

How it works in practice

Build a filing calendar into the deal timeline. Share enough commercial data for a threshold test early—preferably before signing if closing is time-sensitive. Multi-jurisdiction deals need parallel EU/US/China workstreams.

FAQ

Do minority investments need filing?

Sometimes. Control and “decisive influence” concepts matter; do not assume “under 50% = no filing.”

Are offshore holding-company deals exempt?

Not automatically if China turnover thresholds and concentration tests are met.
