Chapter 72 covers iron and steel and articles thereof, including pig iron, ferroalloys, scrap, primary products and semi-finished products, etc. This chapter is one of the most important metal chapters in international trade, involving a wide range of commodities from raw materials to semi-finished products. Heading 7218 pertains to primary stainless steel products, distinct from subsequent processed products under 7219 and 7220, and is a high-value-added and strictly regulated category in steel trade. Heading 7218 covers stainless steel ingots or other primary forms of stainless steel, as well as stainless steel semi-finished products (such as billets, slabs, round blooms, etc.). These products are typically obtained through continuous casting or ingot casting and are used for subsequent rolling or forging. Goods under this heading must meet the definition of stainless steel (chromium content ≥10.5% by weight) and must not have undergone further processing (such as hot rolling, cold rolling, etc.). The first 2 digits 72 represent the iron and steel chapter; digits 3-4, 18, represent the heading for primary stainless steel products; digits 5-6, 99, is the subheading indicating "other" primary stainless steel products, i.e., primary form stainless steel not listed under other specific subheadings of 7218 (such as 721810, 721891, etc.). Specifically, 721810 covers stainless steel ingots and primary forms, 721891 covers rectangular cross-section semi-finished products, and 721899 covers primary products of other shapes or compositions, such as blooms other than round or square, or primary stainless steel products with specific alloying element content. Classification under 721899 rather than adjacent codes is mainly because the product form or composition does not conform to a more specific subheading. For example, if it is a rectangular cross-section semi-finished product, it should be classified under 721891; if it is a stainless steel ingot, it should be classified under 721810. As a residual subheading, 721899 applies to other primary form stainless steel not elsewhere specified, such as round blooms, profiled blooms, or primary stainless steel products containing specific elements.

Product Name: The specific name of the declared commodity, such as "stainless steel round bloom," "stainless steel profiled bloom," etc., which must be consistent with the actual goods. Material: Indicate the grade or composition of the stainless steel, such as 304, 316, etc., and state whether the chromium content is ≥10.5%. Shape: Describe the physical shape of the primary product, such as round bloom, square billet, profiled bloom, etc., which must correspond to 721899. Specifications and Dimensions: Provide cross-sectional dimensions, length, etc., such as diameter, side length, thickness, etc., in millimeters. Degree of Processing: Declare whether the product has undergone further processing such as rolling or forging; primary products should be unprocessed. Composition Content: List the content of main alloying elements, such as chromium, nickel, molybdenum, etc., to demonstrate compliance with the definition of stainless steel. Origin: The country or region of production, affecting tariffs and trade policies. Product Name: Stainless steel round bloom; Material: 304 stainless steel, chromium content 18.2%, nickel 8.1%; Shape: round bloom; Specifications: diameter 200mm, length 6000mm; Degree of Processing: continuous cast, not rolled; Composition Content: C 0.05%, Cr 18.2%, Ni 8.1%, Mn 1.5%; Origin: Japan. Misclassifying rectangular cross-section semi-finished products under 721899 when they should be classified under 721891. Failing to provide chromium content certification, resulting in inability to identify as stainless steel. Incorrectly declaring hot-rolled primary products as unprocessed primary forms.

The core basis for classification is: 1) The material must be stainless steel (chromium content ≥10.5%); 2) The form must be primary product (ingot, billet, etc.) or semi-finished product; 3) It must not have undergone further processing such as rolling or forging; 4) The shape or composition does not conform to other specific subheadings under 7218. As a residual subheading, 721899 applies to other primary stainless steel products not elsewhere specified. 721810 Stainless steel ingots and primary forms: 721810 covers only ingots and similar primary forms, while 721899 covers other semi-finished products such as round blooms and profiled blooms. 721891 Rectangular cross-section stainless steel semi-finished products: 721891 specifically refers to rectangular cross-sections (square billets, slabs), while 721899 is used for non-rectangular cross-sections. 721990 Other stainless steel semi-finished products: 721990 belongs to heading 7220 and refers to stainless steel semi-finished products that have undergone further rolling, while 721899 is for primary forms. 722490 Other alloy steel semi-finished products: 722490 pertains to other alloy steel, not stainless steel; the core difference lies in the material. Confirm whether chromium content is ≥10.5%? Is the product in primary form or semi-finished form? Has it not undergone rolling, forging, or other processing? Is the cross-sectional shape non-rectangular? Have other specific subheadings under 7218 been excluded?

How to check the tariff rate for 721899? The latest tariff rate can be checked through the website of the General Administration of Customs of China or the International Trade Single Window, and can also be referenced in the Import and Export Tariff of the People's Republic of China. Tariff rates may vary due to trade agreements, origin, and other factors; it is recommended to refer to the latest official publication. What is the main difference between 721899 and 721891? 721891 specifically refers to rectangular cross-section stainless steel semi-finished products (such as square billets, slabs), while 721899 applies to other shapes (such as round blooms, profiled blooms) or primary products with special compositions. When classifying, the cross-sectional shape must be carefully verified. Is material certification required for declaration? Yes, material certification or composition analysis reports must be provided to prove that the chromium content is ≥10.5%, meeting the definition of stainless steel. Otherwise, it may be classified under other alloy steel headings. If the product has been hot-rolled, can it still be classified under 721899? No. 721899 applies only to primary products that have not undergone further processing. If hot-rolled, it should be classified under the corresponding subheading of heading 7220, such as 721990. What is the export tax rebate rate for 721899? The export tax rebate rate is subject to national policy adjustments and should be checked in the latest export tax rebate rate database. Generally, the rebate rate for primary stainless steel products is relatively low. It is recommended to consult the local tax authority or customs broker. What regulatory documents are required for importing 721899? Generally, an automatic import license (if applicable), certificate of origin, quality inspection certificate, etc., are required. Specific regulatory conditions should be based on the latest customs regulations; consult the Customs Import and Export Tariff or a customs broker. How to determine whether a product is a "primary product"? Primary products refer to those obtained through casting or continuous casting, without rolling, forging, or other plastic processing. If only surface grinding or cutting has been performed, it can still be considered a primary product. Is the classification of 721899 affected by dimensions? Dimensions themselves do not affect classification, but shape and degree of processing are key. For example, rectangular cross-sections are classified under 721891 regardless of dimensions, while non-rectangular cross-sections are classified under 721899.
