Despite its abundant domestic PVC capacity, China still imports 150,000 to 160,000 metric tons of PVC paste resin (total value US$160 million to 170 million) annually.

China's State Council recently amended the tariff regulations so that PVC paste resin no longer shares the same tariff coding with general PVC powder. China Trade News commented that the change will "help with the healthy growth of domestic manufacturers of PVC paste resin."

China has been imposing anti-dumping charges on imported PVC powder since 2003. "But because general PVC powder was not distinguished from PVC paste resin, it was difficult for authorities and organizations to effectively monitor the pricing and trading of imported PVC powder; therefore, the industry couldn't accurately assess the effectiveness of the anti-dumping measures," the report said.

The tariff coding for general PVC power is 39041000 and the coding for PVC paste resin is 39041010.
