Initiation of countervailing duty investigations of float glass products from the People's Republic of China (C-570-189) and Malaysia (C-557-833)

Plain-English explanation

CSMS 5016407 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on January 16, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "Initiation of countervailing duty investigations of float glass products from the People's Republic of China (C-570-189) and Malaysia (C-557-833)". It links to 2 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 01/08/2025, Commerce published in the Federal Register its initiation of the countervailing duty investigations of float glass products from the People's Republic of China and Malaysia (90 FR 1443). The effective date of this initiation is 12/31/2024 (the applicable date stated in the FR notice). 2. The scope of these investigations covers float glass products (FGP), which are articles of sodalime-silica glass that are manufactured by floating a continuous strip of molten glass over a smooth bath of tin (or another liquid metal with a density greater than molten glass), cooling the glass in an annealing lehr, and cutting it to appropriate dimensions. For purposes of the investigations, float glass products have an actual thickness of at least 2.0 mm (0.0787 inches) and an actual surface area of at least 0.37 square meters (4.0 square feet). The country of origin of each float glass product is determined by the location where the soda-lime-silica glass is first manufactured by floating a continuous strip of molten glass over a smooth bath of tin and cooling the glass in an annealing lehr, regardless of the location of any downstream finishing or fabrication operations. Prior to being subjected to further treatment, finishing, or fabrication, float glass products meet the requirements of Type I under ASTM-C1036 of the American Society for Testing and Materials (ASTM). Float glass products may be clear, stained, tinted, or coated with one or more materials. Examples of coated float glass products include Low-E architectural glass (i.e., glass with a low emissivity coating to limit the penetration of radiant heat energy) and frameless mirrors (i.e., flat glass with a silver, aluminum, or other reflective layer) such as mirror stock sheet. Float glass products may be annealed, chemically strengthened, heat strengthened, or tempered to achieve a desired surface compression, pursuant to ASTM-C1048, ASTM-C1422/C1422M, or other similar specifications. Float glass products include tub and shower enclosures (i.e., doors and panels) made of tempered glass, which may be sold with attached or unattached hardware. In such cases, the scope covers only the tempered glass, to the exclusion of any non-glass hardware. The only float glass product assemblies included within the scope are: (1) articles consisting of two of more sheets of float glass that are bonded together using a polymer interlayer (i.e., laminated glass); (2) insulating glass units (IGUs), which consist of two or more sheets of float glass separated by a spacer material and hermetically sealed together at the edge in order to create a thermal barrier using air or one or more gases; and (3) LED mirrors (i.e., float glass mirrors with one or more light-emitting diodes integrated with the mirror, as well as framed float glass mirrors with one or more light-emitting diodes integrated with the mirror or the mirror frame, but without other electronic functionality). Float glass products covered by the scope may meet one or more of the ASTM-C162, ASTMC1036, ASTM-C1048, ASTM-C1172, ASTM-C1349, ASTM-C1376, ASTM-C1422/C1422M, ASTM-C1464, ASTM-C1503, ASTM-C1651, ASTM-E1300, and ASTM-E2190 specifications, definitions, and/or standards. Float glass products may be further worked, including, but not limited to, operations such as: cutting; beveling; edging; notching; drilling; etching; bending; curving; chipping; embossing; engraving; surface grinding; or polishing; and sandblasting (i.e., using high velocity air to stream abrasive particles and thereby impart a frosted aesthetic to the glass surface). A float glass product which undergoes further work remains within the scope so long as the soda-lime-silica glass originally satisfied the requirements of ASTM-C1036 Type I and was first manufactured in a subject country, regardless of where it is further worked. Excluded from the scope are: (1) wired glass (i.e., glass with a layer of wire mesh embedded within); (2) patterned flat glass (i.e., rolled glass with a pattern impressed on one or both sides) meeting the requirements of Type II under ASTM-C1036, including greenhouse glass and patterned solar glass (i.e., photovoltaic glass with a textured surface); (3) safety glazing materials for vehicles certified to American National Standards Institute (ANSI) Standard Z26.1; (4) vacuum insulating glass (VIG) units, which consist of two or more sheets of float glass separated by a spacer material, with at least one hermetically sealed compartment that uses a gas-free vacuum as a thermal barrier; (5) framed mirrors without any LEDs integrated with the mirror or the mirror frame; (6) unframed "over-the-door" mirrors that are ready for use as imported without undergoing after importation any processing, finishing, or fabrication; and (7) heat-strengthened washing machine lid glass with an actual surface area less than 6.0 square feet (0.56 square meters). Also excluded from the scope of the investigations are: (1) soda-lime-silica glass containing less than 0.01 percent iron oxide by weight, annealed with a surface compression less than 3,500 pounds per square inch (PSI), having a transparent conductive oxide base coating (e.g., tin oxide), and with an actual thickness less than or equal to 4.0 mm (0.1575 inches) (i.e., "coated solar glass"); and (2) heat treated soda-lime-silica glass with a surface compression between 3,500 and 10,000 PSI, containing two or more drilled holes, and having an actual thickness less than 2.5 mm (0.0984 inches) (i.e., "clear back solar glass"). Solar glass products (also known as photovoltaic glass) are designed to facilitate the conversion of solar energy into electricity. Also excluded from the scope of the investigations are any products already covered by the scope of any extant antidumping and/or countervailing duty orders, including Aluminum Extrusions from the People's Republic of China: Antidumping Duty Order, 76 FR 30650 (May 26, 2011), and Aluminum Extrusions from the People's Republic of China: Countervailing Duty Order, 76 FR 30653 (May 26, 2011). The products subject to the investigations are currently classifiable under subheadings 7005.10.8000, 7005.21.1010, 7005.21.1030, 7005.21.2000, 7005.29.1810, 7005.29.1850, 7005.29.2500, 7007.29.0000, 7008.00.0000, 7009.91.5010, 7009.91.5095, and 7009.92.5010 of the Harmonized Tariff Schedule of the United States (HTSUS). Products subject to the investigations may also enter under HTSUS subheadings 7006.00.4010, 7006.00.4050, and 7007.19.0000. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope of the investigations is dispositive. 3. These proceedings have been assigned case numbers: C-570-189 (China) and C-557-833 (Malaysia). 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 OV:JR.) 5. There are no restrictions on the release of this information. Alexander Amdur
