On March 18, 2025, CoolSeal USA Inc., Inteplast Group Corporation, SeaCa Plastic Packaging, and Technology Container Corp. (collectively “Petitioners”), filed a petition for the imposition of antidumping and countervailing duties on U.S. imports of polypropylene corrugated boxes from the People’s Republic of China and the imposition of antidumping duties on imports of such boxes from the Socialist Republic of Vietnam.  

SCOPE OF THE INVESTIGATION

The merchandise covered by these investigations is Polypropylene Corrugated Boxes (“PCBs”). PCBs are boxes, totes, or other containers made of corrugated polypropylene sheets, also known as polypropylene hollow core sheets, polypropylene twin wall sheets, or multi wall sheets. Such polypropylene sheets are typically produced using a continuous extrusion process from a plastic resin consisting of 50 percent or more polypropylene.

PCBs are covered by the scope irrespective of the particular mix of polypropylene homo-polymer, polypropylene co-polymer, recycled or virgin polypropylene, or ancillary chemicals such as electrostatic agents or flame retardants. PCBs are formed by corrugated polypropylene sheets cut to discrete lengths, scored for folding edges, and die-cut into specific box formats. PCBs may be printed with ink or digital designs. PCBs may enter the United States in folded form or may enter unfolded and later be constructed to form a box shape with a bottom wall and side walls. Unfolded and constructed PCBs may have manufacturers’ joints to retain their final shape.

The subject merchandise includes PCBs with or without handles, with or without lids or tops, with or without reinforcing wire, and whether in a one-piece or multi-piece configuration.

The products subject to the investigations are currently classified in the Harmonized Tariff Schedule of the United States (HTSUS) under statistical reporting number 3923.10.9000. Although the HTSUS statistical reporting number is provided for convenience and customs purposes, the written description of the merchandise is dispositive.
