Initiation of antidumping duty investigation of polypropylene corrugated boxes from the People's Republic of China (A-570-207)

Plain-English explanation

CSMS 5142404 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on May 22, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Initiation of antidumping duty investigation of polypropylene corrugated boxes from the People's Republic of China (A-570-207)". It links to 1 AD/CVD case in Tandom's catalog. CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

Full text as published by U.S. Customs and Border Protection

1. On 04/14/2025, Commerce published in the Federal Register its initiation of the antidumping duty investigation of polypropylene corrugated boxes from the People's Republic of China (90 FR 15544). The effective date of this initiation is 04/07/2025 (the applicable date stated in the FR notice). On 05/20/2025, Commerce published in the Federal Register a correction of the case number assigned to this investigation (90 FR 21455). 2. The merchandise covered by this investigation is polypropylene corrugated boxes. Polypropylene corrugated boxes are boxes, bins, totes, or other load-bearing containers made for holding goods, that are made of corrugated polypropylene sheets, also known as polypropylene hollow core sheets, polypropylene fluted sheets, polypropylene twin wall sheets, or multi wall sheets. Such polypropylene sheets are "corrugated," "fluted," or "hollow core," meaning the inside of the sheet contains channels or pockets of air which make the sheets lightweight, while retaining strength and durability. Polypropylene corrugated boxes are typically produced from a plastic resin consisting of 50 percent or more polypropylene. Polypropylene corrugated boxes 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. Polypropylene corrugated boxes are formed by corrugated polypropylene sheets cut to length, die-cut into specific box shapes, and may be cut or scored to allow each side of the box to be folded into shape. Polypropylene corrugated boxes may include a tab or attached portion of polypropylene corrugated sheet (commonly referred to as a "manufacturer's joint") that has been cut, slotted, or scored to facilitate the formation of the box by stapling, gluing, welding, or taping the sides together to form a tight seal. One-piece polypropylene corrugated boxes are die-cut or otherwise formed so that the top, bottom, and sides form a single, contiguous unit. Two-piece polypropylene corrugated boxes are those with a folded bottom and a folded top as separate pieces. Multi-piece polypropylene corrugated boxes are those with separate bottoms and tops that are fitted to a single folded piece comprising the sides of the box. Polypropylene corrugated boxes may be printed with ink or digital designs. The subject merchandise includes polypropylene corrugated boxes with or without handles, with or without lids or tops, with or without reinforcing wire, whether in a one-piece, two-piece, or multi-piece configuration, and whether folded into shape or in an unfolded form. The subject merchandise includes all polypropylene corrugated boxes regardless of size, shape, or dimension. The subject merchandise also includes polypropylene corrugated box lids or tops when imported separately from polypropylene corrugated boxes. The products subject to this investigations is 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. 3. This proceeding has been assigned case number A-570-207. 4. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIII:PZ.) 5. There are no restrictions on the release of this information.

When was CSMS 5142404 published?

CBP published CSMS 5142404 on May 22, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
