Chapter 70 covers glass and glassware, including glass in various forms (such as blocks, sheets, tubes, balls, etc.) and finished glass products (such as glassware, glass fiber, glass instruments, etc.). This chapter does not include imitation jewelry of glass (Chapter 71), toys of glass (Chapter 95), or optical fiber cables (Chapter 85), etc. Glass balls, as semi-finished or primary glass products, are typically used for further processing or as industrial raw materials, and therefore are classified under this chapter. Heading 7002 covers unworked glass balls (excluding microspheres), glass rods, glass tubes, and unworked articles thereof. Specifically, it includes: glass balls (except glass microspheres of heading 7018), glass rods, glass tubes (whether or not cut into segments, but not further worked), and unworked glass tubing. Products under this heading are typically used for further processing, such as drawing, blowing, cutting, etc., and are important intermediate products of the glass industry. HS code 700210 is a 6-digit subheading. The first 2 digits '70' represent Chapter 70 (Glass and glassware), indicating that the goods belong to glass products. The 3rd-4th digits '02' represent heading 7002 (Unworked glass balls, rods, and tubes), covering glass products in primary forms such as balls, rods, and tubes. The 5th-6th digits '10' represent subheading 700210, specifically referring to glass balls. Therefore, 700210 completely represents 'glass balls,' i.e., glass balls that have not undergone further processing, used for industrial purposes or further processing. Glass balls are classified under 700210 because they are unworked glass balls, conforming to the description of heading 7002. If glass balls have undergone further processing (such as grinding, polishing, drilling, etc.), they may be classified under other headings, such as 7006 (worked glass). If they are glass microspheres (diameter ≤1mm), they are classified under 7018. Therefore, unworked glass balls are correctly classified under 700210.

Product Name: The Chinese and English names of the declared goods, which should be accurately described as '玻璃球' or 'Glass ball,' avoiding colloquial or vague names. Material: Specify the type of glass, such as soda-lime glass, borosilicate glass, quartz glass, etc. Different materials may affect classification and tariff rates. Use: Describe the final use of the glass balls, such as for grinding media, fillers, decoration, further processing, etc. Processing State: Declare whether further processing has been carried out (such as polishing, grinding, drilling, etc.). The unworked state is key to classification under 700210. Size: Provide the diameter range of the glass balls, especially to distinguish whether they are microspheres (diameter ≤1mm). Microspheres should be classified under 7018. Appearance: Describe color, transparency, surface condition, etc., such as colorless transparent, colored, with bubbles, etc. Brand: If there is a brand, declare the brand name; if no brand, declare 'no brand.' Model: If there is a model, declare it; if no model, declare 'no model.' Product Name: Glass ball; Material: Soda-lime glass; Use: Used as grinding media; Processing State: Unworked; Size: Diameter 5mm; Appearance: Colorless transparent; Brand: No brand; Model: No model. Confusing glass balls with glass microspheres; microspheres should be classified under 7018, not 700210. Failing to accurately declare processing state; polished glass balls may be classified under 7006. Ignoring size declaration, making it impossible to determine whether they are microspheres. Material declaration is not specific, which may affect classification and tariff rates. Use description is vague, which may trigger customs questioning.

The core criteria for classification are: whether the glass balls are in an unworked state and do not belong to microspheres. According to HS notes, heading 7002 includes unworked glass balls, but excludes glass microspheres of heading 7018. Therefore, if the glass ball diameter is greater than 1mm and has not undergone further processing, it is classified under 700210; if the diameter is ≤1mm, it is classified under 7018; if it has undergone polishing, grinding, or other processing, it may be classified under 7006. 7018 Glass microspheres: Glass microspheres refer to glass balls with a diameter not exceeding 1mm, used for reflection, filling, etc., classified under 7018; while glass balls under 700210 typically have a diameter greater than 1mm. 7006 Worked glass: 7006 covers glass that has undergone grinding, polishing, drilling, or other processing, while 700210 is limited to unworked glass balls. 7003 Glass blocks, sheets, etc.: 7003 covers glass blocks, sheets, plates, etc., while 700210 specifically refers to glass balls. 7004 Drawn or blown glass sheets: 7004 covers glass sheets, while 700210 is glass balls, which have a different shape. 7013 Glassware: 7013 covers glass tableware, kitchenware, etc., while 700210 is industrial glass balls. Confirm whether the glass ball diameter is greater than 1mm? Confirm whether the glass balls are unworked? Confirm whether the material of the glass balls is clear? Confirm whether the use is specific? Confirm whether they are microspheres?

What is the difference in HS codes between glass balls and glass microspheres? Glass balls (diameter >1mm, unworked) are classified under 700210; glass microspheres (diameter ≤1mm) are classified under 7018. The two are strictly distinguished in classification, and accurate dimensions must be provided during declaration. If glass balls are polished, which code should they be classified under? Polished glass balls have exceeded the unworked scope and should be classified under 7006 (worked glass), not 700210. How to determine whether glass balls are 'unworked'? Unworked means that after forming, the glass balls have not undergone any further treatment, such as grinding, polishing, drilling, etc. Only cutting or simple cleaning is generally considered unworked. Does the material of glass balls affect the HS code? Material generally does not affect the 6-digit subheading, but may affect the tariff rate. For example, quartz glass balls and soda-lime glass balls are both classified under 700210, but the tariff rates may differ. What key elements are required when declaring glass balls? Product name, material, use, processing state, size, appearance, brand, model, etc. are required. Among these, processing state and size are key to classification. If glass balls are used for decoration, are they still classified under 700210? If the glass balls are unworked and have a diameter >1mm, even if used for decoration, they are still classified under 700210. However, if they have undergone processing (such as dyeing, coating), they may be classified under other headings. Where can I find the accurate HS code for glass balls? You can consult the 'Import and Export Tariff of the People's Republic of China' or the 'Commodity Classification Decisions' issued by the General Administration of Customs, or use the customs advance classification service. Are HS codes consistent when exporting glass balls to different countries? The first 6 digits of the HS code are unified internationally, but individual countries may adjust the last 4 digits. When exporting, the complete code must be confirmed according to the destination country's tariff schedule.
