This is an informational message. No action is required. 1. AD/CVD orders generally cover products from a particular country. In some cases, however, products from the country subject to the AD/CVD order may undergo completion or assembly in a third country prior to export or sale to the United States. The products may remain subject to the AD/CVD order despite the completion or assembly that occurs in the third country. However, for CBP purposes, the country of origin for such products may be the third country where the completion or assembly occurred. For technical reasons, the country of the AD/CVD case number must match the CBP country of origin in the entry summary documentation. Accordingly, Commerce establishes third country AD/CVD case numbers that match the CBP country of origin for CBP purposes. 2. Merchandise covered by the Order is pure magnesium regardless of chemistry, form or size, unless expressly excluded from the scope of the Order. Pure magnesium is a metal or alloy containing by weight primarily the element magnesium and produced by decomposing raw materials into magnesium metal. Pure primary magnesium is used primarily as a chemical in the aluminum alloying, desulfurization, and chemical reduction industries. In addition, pure magnesium is used as an input in producing magnesium alloy. Pure magnesium encompasses products (including, but not limited to, butt ends, stubs, crowns and crystals) with the following primary magnesium contents: (1) Products that contain at least 99.95% primary magnesium, by weight (generally referred to as "ultra pure" magnesium) Magnesium Alloy" (2) Products that contain less than 99.95%, but not less than 99.8%, primary magnesium, by weight (generally referred to as "pure" magnesium); and (3) Products that contain 50% or greater, but less than 99.8% primary magnesium, by weight, and that do not conform to ASTM specifications for alloy magnesium (generally referred to as "off-specification pure" magnesium). "Off-specification pure" magnesium is pure primary magnesium containing magnesium scrap, secondary magnesium, oxidized magnesium or impurities (whether or not intentionally added) that cause the primary magnesium content to fall below 99.8% by weight. It generally does not contain, individually or in combination, 1.5% or more, by weight, of the following alloying elements: aluminum, manganese, zinc, silicon, thorium, zirconium and rare earths. Excluded from the scope of the Order are alloy primary magnesium (that meets specifications for alloy magnesium), primary magnesium anodes, granular primary magnesium (including turnings, chips and powder) having a maximum physical dimension ( i.e., length or diameter) of one inch or less, secondary magnesium (which has pure primary magnesium content of less than 50% by weight), and remelted magnesium whose pure primary magnesium content is less than 50% by weight. Pure magnesium products covered by the Order are currently classifiable under Harmonized Tariff Schedule of the United States (HTSUS) subheadings 8104.11.00, 8104.19.00, 8104.20.00, 8104.30.00, 8104.90.00, 3824.90.11, 3824.90.19 and 9817.00.90. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope is dispositive. 3. Effective 05/01/2024, Commerce established a third-country case number to allow pure magnesium completed/assembled in the Republic of Korea to be properly reported as subject to the order on pure magnesium from the People's Republic of China (A-570-832) upon entry. Third Country: Republic of Korea Case Number: A-580-832 Producer and/or Exporter: All Others Case Number: A-580-832-000 Cash Deposit Rate: 111.73% The third country AD/CVD case number above has been assigned for CBP purposes. 4.
