China will impose temporary anti-dumping measures in the form of security deposits on imports of polyphenylene sulfide (PPS) from Japan, the U.S., South Korea and Malaysia, said Ministry of Commerce (MOFCOM) on Friday.

The importers will have to provide the corresponding margin to China Customs based on each company's margin ratio determined by the preliminary ruling when importing the products from October 17.

The MOFCOM preliminary investigation ruled that there was illegal dumping of imported polyphenylene sulfide originating from Japan, the U.S, South Korea and Malaysia.

PPS, a high-performance engineering thermoplastic, is widely used in textile, automobile, electronics, machinery, and aerospace industries.
