Initiation of antidumping duty investigations of mattresses from Bosnia and Herzegovina (CBP Number A-479-902, Commerce Number A-893-002), Bulgaria (A-487-001), Burma (A-546-001), India (A-533-919), Italy (A-475-845), Kosovo (CBP Number A-480-100, Commerce Number A-803-001), Mexico (A-201-859), the Philippines (A-565-804), Poland (A-455-807), Slovenia (CBP Number A-479-504, Commerce Number A-856-002), Spain (CBP Number A-470-400, Commerce Number A-469-826)), and Taiwan (A-583-873)

Plain-English explanation

CSMS 3242405 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on August 30, 2023. It carries the official CBP guidance brokers and importers must follow for the topic — "Initiation of antidumping duty investigations of mattresses from Bosnia and Herzegovina (CBP Number A-479-902, Commerce Number A-893-002), Bulgaria (A-487-001), Burma (A-546-001), India (A-533-919), Italy (A-475-845), Kosovo (CBP Number A-480-100, Commerce Number A-803-001), Mexico (A-201-859), the Philippines (A-565-804), Poland (A-455-807), Slovenia (CBP Number A-479-504, Commerce Number A-856-002), Spain (CBP Number A-470-400, Commerce Number A-469-826)), and Taiwan (A-583-873)". It links to 16 AD/CVD cases 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.

1. On 08/23/2023, Commerce published in the Federal Register its initiation of the antidumping duty investigations of mattresses from Bosnia and Herzegovina, Bulgaria, Burma, India, Italy, Kosovo, Mexico, the Philippines, Poland, Slovenia, Spain, and Taiwan (88 FR 57433). The effective date of this initiation is 08/17/2023 (the applicable date stated in the FR notice). 2. The products covered by these investigations are all types of youth and adult mattresses. The term "mattress" denotes an assembly of materials that at a minimum includes a "core," which provides the main support system of the mattress, and may consist of innersprings, foam, other resilient filling, or a combination of these materials. Mattresses also may contain: (1) "upholstery," the material between the core and the top panel of the ticking on a single-sided mattress, or between the core and the top and bottom panel of the ticking on a double-sided mattress; and/or (2) "ticking," the outermost layer of fabric or other material (e.g., vinyl) that encloses the core and any upholstery, also known as a cover. The scope of these investigations is restricted to only "adult mattresses" and "youth mattresses." "Adult mattresses" are frequently described as "twin," "extra-long twin," "full," "queen," "king," or "California king" mattresses. "Youth mattresses" are typically described as "crib," "toddler," or "youth" mattresses. All adult and youth mattresses are included regardless of size and size description or how they are described (e.g., frameless futon mattress and tri-fold mattress). The scope encompasses all types of "innerspring mattresses," "non-innerspring mattresses," and "hybrid mattresses." "Innerspring mattresses" contain innersprings, a series of metal springs joined together in sizes that correspond to the dimensions of mattresses. Mattresses that contain innersprings are referred to as "innerspring mattresses" or "hybrid mattresses." "Hybrid mattresses" contain two or more support systems as the core, such as layers of both memory foam and innerspring units. "Non-innerspring mattresses" are those that do not contain any innerspring units. They are generally produced from foams (e.g., polyurethane, memory (viscoelastic), latex foam, gel infused viscoelastic (gel foam), thermobonded polyester, polyethylene) or other resilient filling. Mattresses covered by the scope of these investigations may be imported independently, as part of furniture or furniture mechanisms (e.g., convertible sofa bed mattresses, sofa bed mattresses imported with sofa bed mechanisms, corner group mattresses, day-bed mattresses, roll-away bed mattresses, high risers, trundle bed mattresses, crib mattresses), or as part of a set (in combination with a "mattress foundation"). "Mattress foundations" are any base or support for a mattress. Mattress foundations are commonly referred to as "foundations," "boxsprings," "platforms," and/or "bases." Bases can be static, foldable, or adjustable. Only the mattress is covered by the scope if imported as part of furniture, with furniture mechanisms, or as part of a set, in combination with a mattress foundation. Excluded from the scope of these investigations are "futon" mattresses. A "futon" is a bi-fold frame made of wood, metal, or plastic material, or any combination thereof, that functions as both seating furniture (such as a couch, love seat, or sofa) and a bed. A "futon mattress" is a tufted mattress, where the top covering is secured to the bottom with thread that goes completely through the mattress from the top through to the bottom, and it does not contain innersprings or foam. A futon mattress is both the bed and seating surface for the futon. Also excluded from the scope are airbeds (including inflatable mattresses) and waterbeds, which consist of air- or liquid-filled bladders as the core or main support system of the mattress. Also excluded is certain multifunctional furniture that is convertible from seating to sleeping, regardless of filler material or components, where such filler material or components are upholstered, integrated into the design and construction of, and inseparable from, the furniture framing, and the outermost layer of the multifunctional furniture converts into the sleeping surface. Such furniture may, and without limitation, be commonly referred to as "convertible sofas," "sofabeds," "sofa chaise sleepers," "futons," "ottoman sleepers," or a like description. Also excluded from the scope of these investigations are any products covered by the existing antidumping duty orders on uncovered innerspring units from the People's Republic of China, South Africa, and the Socialist Republic of Vietnam. See Uncovered Innerspring Units from the People's Republic of China, South Africa, and Socialist Republic of Vietnam: Continuation of Antidumping Duty Orders, 84 FR 55285 (October 16, 2019). Also excluded from the scope of these investigations are bassinet pads with a nominal length of less than 39 inches, a nominal width of less than 25 inches, and a nominal depth of less than 2 inches. Additionally, also excluded from the scope of these investigations are "mattress toppers." A "mattress topper" is a removable bedding accessory that supplements a mattress by providing an additional layer that is placed on top of a mattress. Excluded mattress toppers have a height of four inches or less. The products subject to these investigations are currently classifiable under Harmonized Tariff Schedule of the United States (HTSUS) subheadings: 9404.21.0010, 9404.21.0013, 9404.21.0095, 9404.29.1005, 9404.29.1013, 9404.29.1095, 9404.29.9085, 9404.29.9087, and 9404.29.9095. Products subject to these investigations may also enter under HTSUS subheadings: 9401.41.0000, 9401.49.0000, and 9401.99.9081. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the merchandise subject to these investigations is dispositive. 3.

CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 3242405 published?

CBP published CSMS 3242405 on August 30, 2023. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Which AD/CVD cases does CSMS 3242405 affect?

CSMS 3242405 references 16 AD/CVD cases (A-201-859, A-455-807, A-469-826, A-470-400, A-475-845, and others). The links on this page take you to each linked order with its current scope, rates, and history.

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.
