📌 I. Product Definition & Classification: What Exactly is "Cork Granules"?

Cork is a unique, natural, renewable material harvested from the bark of the Cork Oak (Quercus suber). In international trade, "Cork Granules" and related cork forms are classified differently based on their physical form (granules, blocks, waste) and degree of processing (raw, simply prepared, or manufactured).

Misclassification is the most common cause of customs delays for cork products because the tariff rates vary drastically—from 22.4% to 49%—depending on whether the product is seen as "raw material," "board material," or "finished block."

⚠️ Key Distinction Points:
- Granules (颗粒): Often used for insulation, flooring underlayment, or industrial fillers. If treated merely as primary classification → 9604.00.00.00.
- Granules for Flooring (颗粒地板材料): If explicitly intended for composite flooring panels → 4410.90.00.00.
- Blocks (块状): Natural or simply prepared cork blocks → 4502.00.00.00 or 4503.
- Processed/Natural Blocks: Distinguishes between raw natural cork (4501/4502) and other prepared cork items (4503).

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

🔍 Critical Reminder:
- Granules vs. Boards: If your granules are explicitly marketed as "flooring material," customs may push you to 4410.90.00.00 (35% tax) instead of the lower-tax 9604.00.00.00 (22.4% tax).
- Blocks: Natural cork blocks (4502) have 0% base tax, while other cork blocks (4503) can have 14% base tax. The difference is significant!
