China has preliminarily determined that imports of pecans, or Carya illinoensis, originating from the United States and Mexico are being dumped and will impose interim anti-dumping measures, the Ministry of Commerce (MOFCOM) said on Monday.

In a statement on its website, MOFCOM said such dumping practices by the two exporting countries have caused material injury to China's domestic industry, with a direct causal relationship existing between the dumped imports and the sustained industrial damage.

The ministry said it has decided to adopt interim anti-dumping measures in the form of security deposits, effective from August 11, 2026.

The preliminary ruling comes after MOFCOM launched the investigation on September 25, 2025.

A spokesperson for the ministry said on Monday in a separate statement that it followed China's anti-dumping laws and World Trade Organization (WTO) rules, and adhered to principles of fairness, impartiality, openness and transparency throughout the probe.

The ministry has ruled dumping margins for Mexican companies range from 17.8% to 51.6%. With no US companies participating in the probe, the ministry set a dumping margin of 54.3% for all American firms in accordance with Chinese laws and WTO rules.

China exercises prudence and restraint in the use of trade remedy measures and remains committed to fair and free trade, the spokesperson said.

China will continue the investigation in accordance with the law, fully safeguard the rights of all interested parties, and issue an objective and fair final ruling based on the investigation results, the spokesperson added.
