Discontinuation of suspension of liquidation in the countervailing duty investigation of thermoformed molded fiber products from the Socialist Republic of Vietnam (C-552-846)

Plain-English explanation

CSMS 5225411 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on August 13, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Discontinuation of suspension of liquidation in the countervailing duty investigation of thermoformed molded fiber products from the Socialist Republic of Vietnam (C-552-846)". 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.

Message body

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

1. In accordance with section 703(d) of the Tariff Act of 1930, as amended (19 U.S.C. Section 1671b(d)), Commerce is instructing CBP to discontinue the suspension of liquidation of entries concerning the countervailing duty investigation of thermoformed molded fiber products from the Socialist Republic of Vietnam effective 07/12/2025, which is the day after provisional measures in this proceeding has been in place for 120 days. 2. The merchandise covered by this investigation has changed. The merchandise subject to this investigation consists of thermoformed molded fiber products regardless of shape, form, function, fiber source, or finish. Thermoformed molded fiber products are formed with cellulose fibers, thermoformed using one or more heated molds, and dried/cured in the mold. Thermoformed molded fiber products include, but are not limited to, plates, bowls, clamshells, trays, lids, food or foodservice contact packaging, and consumer or other product packaging. Thermoformed molded fiber products are relatively dense, with a typical fiber density above 0.5 grams per cubic centimeter, and are generally characterized by relatively smooth surfaces. They may be derived from any virgin or recycled cellulose fiber source (including, but not limited to, those sourced from wood, woody crops, agricultural crops/byproducts/residue, and agricultural/industrial/other waste). They may have any weight, shape, dimensionality, design, or size, and may be bleached, unbleached, dyed, colored, or printed. They may include ingredients, additives, or chemistries to enhance functionality including, but not limited to, anti-microbial, anti-fungal, anti-bacterial, heat/flame resistant, hydrophobic, oleophobic, absorbent, or adsorbent. Thermoformed molded fiber products may also be subject to other processing or treatments, including, but not limited to, hot or after pressing, die-cutting, punching, trimming, padding, perforating, printing, labeling, dying, coloring, coating, laminating, embossing, debossing, repacking, or denesting. Thermoformed molded fiber products subject to this investigation may also have additional design features, including, but not limited to, tab closures, venting, channeling, or stiffening. Thermoformed molded fiber products remain covered by the scope of this investigation if the subject product is encased by exterior packaging. They also remain covered by the scope of this investigation whether imported alone, or in any combination of subject and non-subject merchandise (e.g., a lid or cover of any type packaged with a molded fiber bowl, addition of any items to make the thermoformed molded fiber packaging suitable for end-use such as absorbent pads). When thermoformed molded fiber products are imported in combination with non-subject merchandise, only the thermoformed molded fiber products are subject merchandise. Also excluded from the scope of this investigation are products covered by the scope of the antidumping and countervailing duty orders on paper plates from People's Republic of China, the Kingdom of Thailand, and the Socialist Republic of Vietnam. Excluded from the scope of this investigation are thermoformed molded fiber products imported as packaging material that enclose and/or surround non-subject merchandise prepackaged for final sale upon importation into the United States (e.g., molded fiber packaging surrounding a cellular phone). Thermoformed molded fiber products include thermoformed molded fiber products matching the above description that have been finished, packaged, or otherwise processed in a third country by performing finishing, packaging, or processing that would not otherwise remove the merchandise from the scope of the investigation if performed in the country of manufacture of the thermoformed molded fiber products. Examples of finishing, packaging, or other processing in a third country that would not otherwise remove the merchandise from the scope of the investigation if performed in the country of manufacture of the thermoformed molded fiber products include, but are not limited to, hot or after pressing, die-cutting, punching, trimming, padding, perforating, printing, labeling, dying, coloring, coating, laminating, embossing, debossing, repacking, or denesting. Thermoformed molded fiber products are classified under subheadings 4823.70.0020 and 4823.70.0040, Harmonized Tariff Schedule of the United States (HTSUS). Imports may also be classified under subheadings 4823.61.0020, 4823.61.0040, 4823.69.0020, 4823.69.0040, 4823.90.1000, HTSUS. References to the HTSUS classification are provided for convenience and customs purposes, and the written description of the merchandise under investigation is dispositive. 3. This proceeding has been assigned case number C-552-846. 4. CBP shall discontinue the suspension of liquidation for countervailing duty purposes on all shipments of subject merchandise entered, or withdrawn from warehouse, for consumption on or after 07/12/2025 (the first day provisional measures is no longer in effect). The suspension of liquidation will not be resumed unless and until a final affirmative determination on this case is published in the Federal Register by the ITC. 5. These discontinuation instructions do not apply to subject merchandise subject to suspension of liquidation and imposition of cash deposits, entered, or withdrawn from warehouse, for consumption on or before 07/11/2025 (the date provisional measures expired in this proceeding). 6. These discontinuation instructions do not affect the requirements of a cash deposit on entries subject to the suspension of liquidation announced in Commerce's preliminary determination in the companion antidumping duty investigation of this merchandise. 7.
