Borosilicate Glass Powder

🧪 Borosilicate Glass Powder (The "Pyrex" Standard) – 2026 Customs Classification & Tariff Deep Dive

🌐 HS Code Reference & Clearance Guide | 2026 Latest Harmonized System | Professional Clearance Strategy

📌 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.

⚠ Key Distinction:
- If it is loose powder, granules, or frit intended for industrial use → Classified under Chapter 70 (Glass and Glassware).
- If it is finished lab equipment (beakers, test Tubes) → Classified under 9026 or 9027 (depending on precision/function).
- If it is optical glass powder for lenses → Still 7005/7007 range, not Chapter 90.

📦 II. Detailed Classification (2026 Harmonized System Authority Matchup

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):

✅ 7002.20.00.00 (if optical/high purity) ✅ 7019.59.00.00 (Incorrect - this is fiber) ✅ 7001.00.00.00 (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 likely 7002.20.00.00 (if sheets/frit for optical) OR 7019.59.00.00 is wrong.

Let's check the most accurate general classification for generic Borosilicate Glass Powder (non-optical, non-fiber):

🚨 Critical Note: Many generic glass powders are classified under 7019.59.00.00 if they are fibrous, but if it is dense powder/granules, it is often classified under 7002.20.00.00 (as "other glass in the form of sheets... or granules") OR 7001.00.00.00 (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:

7002.20.00.00

Description: 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 7002.20.00.00 for glass powder/granules/frit.

🔍 Key Reminder:
- 7002.20.00.00 is the safest bet for Borosilicate Glass Powder/Granules/Frit.
- Do NOT classify as 7019.59.00.00 unless it is glass fiber.
- Do NOT classify as 7001.00.00.00 unless it is glass wool/mineral wool.

💰 III. 2026 Latest Tariff Rate Details (Including Surtaxes, Policy Add-ons

✅ Target Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: November 10, 2025 onwards

🎯 1. 7002.20.00.00 —— Borosilicate Glass Powder/Granules/Frit

📌 Explanation:
- "USITC Surtax 25%" is from the Section 301 Tariff List;
- "IEEPA 10%" is the Additional Tariff on Chinese Goods;
- Total 35%, which is a high tariff cost, must be factored in advance!

🎯 2. 7002.20.00.00 —— Alternative Considerations

If the glass powder is not Borosilicate but Soda-Lime or Lead Glass, the classification might shift, but 7002.20.00.00 remains the general container for "Glass Powder/Granules/Frit."

📌 Note:
- All glass powders/granules/frit fall under this tariff structure;
- Even if it's "Optical Glass Powder," "Laboratory Glass Powder," or "Ceramic Glaze Glass Frit," as long as it's glass powder/granules, it applies.

❌ Mistake 2: Using 7001.00.00.00 (Glass Wool for Borosilicate Powder
👉 Consequence: Wrong Chapter → Penalty + Back Taxes!

❌ Mistake 3: Missing MSDS for Powdered Products
👉 Consequence: Customs无法判断是否危险化学品 → Inspection Delay!

❌ Mistake 4: Using 9026.80.00.00 (Lab Equipment for Raw Powder
👉 Consequence: Wrong Classification → 35% Tariff vs 0% Base (if misclassified as equipment, it might be different, but usually powder is 0% base, equipment is 0% base, but surcharge applies to both).

✅ Right Way:
