Chapter 70 covers glass and glassware, including flat glass, glass fibers, glassware, glass instruments, etc. This chapter classifies headings based on the processing stage, shape, and use of glass, covering everything from raw glass to finished glass products. However, glass imitation jewelry, optical elements, etc. may be classified under other chapters. Heading 7003 covers cast or rolled non-wired glass sheets, plates, or profiles, whether or not surface ground or polished, but not further worked. Includes cast or rolled glass in the mass, as well as glass plates for building use. However, it does not include wired glass (7004) or tempered glass (7007). First 2 digits 70 = Chapter: Glass and glassware; digits 3-4 03 = Heading: Cast or rolled glass sheets, plates, or profiles, non-wired; digits 5-6 20 = Subheading: Cast or rolled wired glass sheets. Note: Subheading 7003.20 specifically refers to wired glass, i.e., glass sheets embedded with metal wire mesh, which is an exception to non-wired glass. This product is cast or rolled wired glass sheets, embedded with metal wire mesh, but not further worked such as tempered or laminated. Therefore, it is classified under 7003.20, not 7004 (wired glass, but further worked such as tempered) or 7005 (float glass).

Product Name: The standard name of the declared commodity, which should be accurately described as 'Cast or Rolled Wired Glass Sheets' Material: Specify the glass material, such as soda-lime glass, borosilicate glass, etc. Processing Method: Indicate whether cast or rolled, and whether surface ground or polished Wired or Not: Clearly state whether embedded with metal wire mesh; this code must be wired Specifications and Dimensions: Provide thickness, width, length, and other dimensional information Use: Describe the main use, such as construction, fireproof doors and windows, etc. Brand: If there is a brand, declare the brand name Model: If there is a model, declare the model Product Name: Cast or Rolled Wired Glass Sheets; Material: Soda-lime glass; Processing Method: Rolled, surface not ground; Wired or Not: Yes; Specifications: Thickness 6mm, Width 2000mm, Length 3000mm; Use: Construction fireproof doors and windows; Brand: No Brand; Model: No Model. Incorrectly classifying wired glass under 7004 (wired glass), but 7004 is further worked wired glass Ignoring the processing method; although cast and rolled are both under 7003, they affect price and use Incomplete declaration of specifications and dimensions, leading to customs questioning classification

Core basis for classification: 1. The product is glass sheets; 2. The processing method is cast or rolled; 3. It contains metal wire mesh; 4. It has not been further worked such as tempered or laminated. If the above conditions are met, it is classified under 7003.20. If tempered, it is classified under 7007; if float glass, under 7005. 7004 Wired Glass: 7004 is further worked wired glass, such as tempered, surface polished, etc.; while 7003.20 is only cast or rolled, not further worked. 7005 Float Glass: 7005 is glass produced by the float process, usually not containing wire; 7003.20 is cast or rolled and contains wire. 7007 Tempered Glass: 7007 is glass that has been tempered, may contain wire, but the processing method is different; 7003.20 is only cast or rolled. 7006 Worked Glass: 7006 is glass that has been further worked by bending, edge working, engraving, etc.; 7003.20 is not further worked. Is it confirmed that the glass is cast or rolled? Is it confirmed that it contains metal wire mesh? Has it not been tempered or laminated? Are the specifications and dimensions complete? Is the use clear?

Can wired glass sheets under HS code 700320 be used for building exterior walls? Yes. Wired glass sheets have certain fireproof and explosion-proof properties and are commonly used for building fireproof doors and windows, partitions, etc. However, note that if used for exterior walls and tempered, they should be classified under 7007 rather than 7003.20. How to distinguish between 700320 and 7004? 700320 is cast or rolled wired glass sheets, not further worked; 7004 is further worked wired glass, such as tempered, polished, etc. The key is whether secondary processing has been done. What specification and dimension information is required for declaration? Thickness, width, and length are required, usually in millimeters. If irregularly shaped, provide the maximum dimensions. Specifications affect classification and valuation, so accuracy is essential. Must the brand and model of wired glass sheets be declared? If there is a brand and model, they must be declared; if not, declare 'No Brand' and 'No Model'. They cannot be omitted, otherwise customs may reject the declaration. What is the export tax rebate rate for 700320? The export tax rebate rate is subject to policy adjustments. It is recommended to check the latest rebate rate through the official website of the State Taxation Administration or the General Administration of Customs, or consult a professional customs broker. What procedures are required for importing wired glass sheets? Generally, basic documents such as contract, invoice, packing list, bill of lading, and customs declaration form are required. If used for building safety, a China Compulsory Certification (CCC) certificate may be required. Specific requirements are subject to customs regulations. If wired glass sheets have been edge-ground, are they still classified under 700320? If only edge-ground without changing the basic characteristics of the glass, they can still be classified under 700320; but if further worked by bending, engraving, etc., they may be classified under 7006.
