Chapter 70 covers glass and glassware, including flat glass, glass fibers, glassware, glass instruments, glass beads, etc. This chapter ranges from raw glass to deeply processed glass products, but excludes glass optical elements (Chapter 90), glass toys (Chapter 95), and glass imitation jewelry (Chapter 71). Glass in this chapter can be of any shape and use, but must comply with the specific provisions of the chapter notes and heading texts. Heading 7003 covers cast or rolled glass in sheets, plates, or profiles, whether or not surface ground or polished, but not otherwise worked. Specifically includes: unworked cast or rolled glass sheets and plates; cast or rolled glass ground or polished but not further worked; and cast or rolled glass profiles. However, it excludes tempered or laminated glass (which falls under 7004 to 7009), and glass products that have been made into specific shapes or for specific uses. Code 700310 is a six-digit subheading. The first 2 digits '70' represent Chapter 70 (Glass and glassware). The 3rd-4th digits '03' represent heading 7003, i.e., cast or rolled glass in sheets, plates, or profiles. The 5th-6th digits '10' represent subheading 7003.10, specifically referring to cast or rolled glass sheets and plates not otherwise worked, i.e., only ground or polished, but not further processed by tempering, laminating, coating, bending, etc. Therefore, the complete meaning of 700310 is: cast or rolled glass sheets and plates, only surface ground or polished, not otherwise worked. This product is classified under 700310 because its manufacturing process is casting or rolling, and it has only been surface ground or polished, without deep processing such as tempering or laminating. If the glass has been tempered, it should be classified under 7004; if laminated, under 7005; if coated or bent, under 7006 to 7009. Therefore, 700310 applies to primarily processed cast or rolled glass sheets.

Digit Breakdown
Code 700310 is a six-digit subheading. The first 2 digits '70' represent Chapter 70 (Glass and glassware). The 3rd-4th digits '03' represent heading 7003, i.e., cast or rolled glass in sheets, plates, or profiles. The 5th-6th digits '10' represent subheading 7003.10, specifically referring to cast or rolled glass sheets and plates not otherwise worked, i.e., only ground or polished, but not further processed by tempering, laminating, coating, bending, etc. Therefore, the complete meaning of 700310 is: cast or rolled glass sheets and plates, only surface ground or polished, not otherwise worked.
Classification Basis
This product is classified under 700310 because its manufacturing process is casting or rolling, and it has only been surface ground or polished, without deep processing such as tempering or laminating. If the glass has been tempered, it should be classified under 7004; if laminated, under 7005; if coated or bent, under 7006 to 7009. Therefore, 700310 applies to primarily processed cast or rolled glass sheets.
📝 Declaration Elements
Product Name: The Chinese and foreign language names of the declared goods, which should accurately reflect the manufacturing process and state of the glass, such as 'cast glass sheet' or 'rolled glass sheet'. Manufacturing Process: Explain the forming method of the glass, such as casting or rolling, and whether it has been ground or polished. Specifications and Dimensions: Declare the thickness, width, length, and other dimensional information of the glass sheet, usually in millimeters or centimeters. Use: Explain the final use of the glass sheet, such as construction, furniture, decoration, etc., but note that use does not affect classification under this code. Surface Condition: Describe whether the glass surface has been ground, polished, or has other coatings. Brand: Declare the production brand or manufacturer name of the glass; if no brand, fill in 'None'. Model: Declare the model or specification code of the glass for easy identification. Product Name: Cast glass sheet; Manufacturing Process: Cast, ground and polished; Specifications: Thickness 5mm, Width 2000mm, Length 3000mm; Use: Construction; Surface Condition: Ground and polished, no coating; Brand: XYZ; Model: G-5. Tempered glass mistakenly classified under 700310, should actually be under 7004. Not indicating grinding and polishing process, leading to confusion with unworked glass. Float glass mistakenly declared as cast or rolled glass; float glass is usually classified under 7005.

⚠️ Not indicating whether it has been ground or polished, or misreporting as float process.
Specifications and Dimensions
Declare the thickness, width, length, and other dimensional information of the glass sheet, usually in millimeters or centimeters.
⚠️ Providing only partial dimensions or using non-standard units.
Use
Explain the final use of the glass sheet, such as construction, furniture, decoration, etc., but note that use does not affect classification under this code.

🎯 Classification Logic
The core criteria for classification are the manufacturing process and processing state of the glass. 700310 only applies to cast or rolled glass sheets that have only been ground or polished. If the glass has undergone any further processing such as tempering, laminating, coating, bending, etc., it is classified under 7004 to 7009. Also, it must be confirmed that the glass is in flat sheet form; profiles are classified under other subheadings of 7003. 7004 Tempered glass: 7004 is glass that has been tempered, while 700310 has not been tempered. Tempered glass has higher strength and safety, and the processing method is different. 7005 Float glass: 7005 is glass produced by the float process, with a flat surface, while 700310 is cast or rolled, and the surface may have texture. Float glass is usually not ground or polished. 7006 Worked glass: 7006 includes glass that has been deeply processed by bending, edge working, engraving, etc., while 700310 has only been ground and polished. 7009 Glass mirrors: 7009 is glass mirrors, i.e., glass with a reflective layer coated on the surface, while 700310 has no reflective layer. Is the manufacturing process confirmed as casting or rolling? Has it only been ground or polished, with no other processing? Is the glass confirmed to be in flat sheet form, not profiles? Are tempering, laminating, etc., excluded? Are dimensions and use checked only for reference?

❓ FAQ
How to determine if a glass sheet belongs to 700310? First confirm the manufacturing process is casting or rolling, not float. Second, check if it has only been ground or polished, without tempering, laminating, coating, bending, etc. If so, classify under 700310. What is the main difference between 700310 and 7004? 700310 is untempered cast or rolled glass sheets, while 7004 is tempered glass. Tempered glass is heat-treated, has higher strength, and breaks into granular pieces. Can float glass be classified under 700310? No. Float glass belongs to 7005 because its manufacturing process is float, not casting or rolling. Float glass has a flat surface and is usually not ground or polished. Where is ground and polished cast glass sheet classified? Still under 700310, because grinding and polishing are surface treatments that do not change its basic characteristics. But if further processed, such as tempered, then under 7004. What are the declaration elements for 700310? Includes product name, manufacturing process, specifications, use, surface condition, brand, model, etc. Detailed description of manufacturing process and processing state is required. If the glass sheet has a coating, can it still be classified under 700310? No. Coated glass is usually classified under 7006 or 7009, depending on the coating type and use. 700310 only applies to uncoated ground and polished glass. How to query the tariff rate for 700310? You can refer to the 'Customs Import and Export Tariff of the People's Republic of China' published by the General Administration of Customs or use the customs classification query system. The rate varies depending on trade agreements and origin. Is there a difference in classification between cast glass and rolled glass? No difference, both are classified under 700310 as long as they have only been ground or polished. But the specific process must be indicated during declaration.
