π HS Code Reference & Clearance Guide | 2026 Latest Harmonized System | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Know "Borosilicate Glass Powder"?
Borosilicate glass is a type of glass with silica and Boron Trioxide as its main components. It has very low coefficient of thermal expansion, making it highly thermally shock-resistant. It is commonly used for laboratory equipment, high-end cookware, and optical applications.
When classified as "Powder," it refers to the raw material form before being fused into final products (like beads, fibers, or molded glass). In international trade, it is crucial to distinguishes between:
- Raw Material (Glass Powder/Granules): Used for manufacturing, coating, or further processing.
- Finished Goods (Labware/Cookware): Finished containers or instruments.
β Key Distinction:
- If it is loose powder, granules, or frit intended for industrial use β Classified under Chapter 70 (Glass and Glassware).
- If it is finished lab equipment (beakers, test Tubes) β Classified under 9026 or 9027 (depending on precision/function).
- If it is optical glass powder for lenses β Still 7005/7007 range, not Chapter 90.
π¦ II. Detailed Classification (2026 Harmonized System Authority Matchup
| HS Code | Product Description | Applicable Scenario | Processing State |
|---|---|---|---|
7002.20.00.00 |
Other glass in the form of sheets or surface, including glass powder, granules, or frit, of a kind used for optical purposes | Optical grade glass powder, high-purity frit for lenses | β Powder/Granule |
7019.40.00.00 |
Glass fibre cloth | Not applicable - this is fabric, not powder | β No |
7019.59.00.00 |
Other glass fibre (including glass wool) | Not applicable - this is fiber, not powder | β No |
7020.00.00.90 |
Other articles of glass | Finished glass items, not raw powder | β No |
7001.00.00.00 |
Glass wool and similar mineral wools (including slag wool) and articles (e.g., mats, rolls) | Not applicable - this is mineral wool, not dense glass powder | β No |
7002.10.00.00 |
Glass in the form of sheets, coated with an absorbent, reflective or non-reflective layer | Not applicable - this is sheet glass | β No |
Correction & Refinement:
While many might look for "Glass Powder" in Chapter 70, the specific subheading depends on the nature of the powder.Most Common Classification for Generic Borosilicate Glass Powder (Industrial/Chemical Use):
β
7002.20.00.00(if optical/high purity) β7019.59.00.00(Incorrect - this is fiber) β7001.00.00.00(Incorrect - this is mineral wool)Wait, let's look closer at the Harmonized System Explanatory Notes for Chapter 70:
There is no single "Glass Powder" line item for general industrial use. However: 1. If it is frit (glass granules/melts for enameling/coating), it often falls under
7019.59.00.00(if fibrous) or more likely7002.20.00.00(if sheets/frit for optical) OR7019.59.00.00is wrong.Let's check the most accurate general classification for generic Borosilicate Glass Powder (non-optical, non-fiber):
π¨ Critical Note: Many generic glass powders are classified under
7019.59.00.00if they are fibrous, but if it is dense powder/granules, it is often classified under7002.20.00.00(as "other glass in the form of sheets... or granules") OR7001.00.00.00(if it's mineral wool, which it isn't).Actually, the most common and correct classification for generic Borosilicate Glass Powder (used in paints, ceramics, or coatings) is:
7002.20.00.00Description: Other glass in the form of sheets or surface, including glass powder, granules, or frit.
Alternative if it's considered "Mineral Wool" (unlikely for Borosilicate):
7001.00.00.00(Avoid unless specified as wool). Alternative if it's "Glass Fibers":7019.59.00.00(Avoid unless it's fiber).Recommendation: Use
7002.20.00.00for glass powder/granules/frit.π Key Reminder:
-7002.20.00.00is the safest bet for Borosilicate Glass Powder/Granules/Frit.
- Do NOT classify as7019.59.00.00unless it is glass fiber.
- Do NOT classify as7001.00.00.00unless it is glass wool/mineral wool.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
