📌 1. Product Definition & Classification: What Exactly Are "Glass Blocks"?

Glass blocks (also known as glass bricks) are architectural elements made primarily of glass, used for windows, partitions, and walls. In international trade, the key to correct classification lies in material composition and form factor.

Key Distinction Points: * Pure Glass Structure: If the block is entirely made of glass (sealed, hollow or solid) → Chapter 70 (Glass and Glassware). * Cement-Based Masonry: If the block is made of cement, stone, or ceramic with glass only as a surface layer or additive → Chapter 68 or 69. * Form: "Brick" shape specifically points to Heading 7016 (Paving, Surfacing, and Building Glass, incl. Bricks, Slabs & Tiles).

⚠️ Critical Compliance Note:
- Misclassifying glass blocks as "stone/cement bricks" (Chapter 68/69) can lead to severe penalties due to origin and tariff discrepancies.
- Pure glass blocks must be declared under Chapter 70.

📦 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

Based on the provided data, here are the five most relevant HS Codes for Glass Blocks imported into the United States from China.

🔍 Important Clarification:
- HS Codes 7016.* and 7020.* are for Pure Glass blocks.
- HS Code 6810.19.12.00 is for Cement/Stone blocks. Do not use this if your product is 100% glass. It will be rejected or misclassified.
- The choice between 7016 and 7020 often depends on whether the block is considered "paving/building glass" (7016) or "other glass articles" (7020). Both are viable for glass blocks, but 7016.90.50.00 is the most precise for "Bricks".
