Thai Companies Master Packaging Co. Ltd. and Thai Plastic Bags Group (TPBG) have been exporting polyethylene retail carrier bags to US. Importers in USA of this merchandise had paid negligible antidumping duty cash deposits at the time of entry will be liable for substantial additional antidumping duties. The U.S. Department of Commerce will instruct U.S. Customs to collect additional antidumping duties on imports of PRCBs from Thailand. This will be for the period of 1st August 2007 – 31st July 2008 manufactured by Master Packaging Co. Ltd.(122.88% on imports) and TPBG (21.99% on imports). TPBG alone exported approximately US$50 mln of merchandise subject to the antidumping order during the period, leaving importers liable for about US$11 mln in duties. The ruling from Commerce Dept will prevent TPBG from further abusing its previously low antidumping duty cash deposit rate and expanding its U.S. market share through unfair pricing. Antidumping orders are also in place on PRCBs from China and Malaysia.
