📌 1. Product Definition & Classification: Do You Truly Understand "Rubber Compound"?

Rubber Compound refers to mixtures where natural rubber is blended with synthetic rubber, fillers, or processing aids. In international trade, the classification hinges on the state of the rubber (primary, intermediate, or vulcanized) and its composition (natural vs. synthetic blend).

Key Distinction:
- Primary/Intermediate Forms: Raw or semi-processed rubber, not yet vulcanized.
- Vulcanized/Mixed Compounds: Pre-mixed or partially processed rubber ready for molding.
- Mixed Blends: Combinations of natural and synthetic rubbers.

⚠️ Critical Classification Point:
- If it is a blend of natural and synthetic rubber → 4002.80.00.00
- If it is natural rubber in primary form (latex, sheets, blocks) → 4001.29.00.00
- If it is natural rubber in intermediate form (crepe, scrap reconstituted) → 4001.22.00.50
- If it is milled/pre-mixed compound (ready for vulcanization) → 4005.99.00.00
- If it is unvulcanized primary compound → 4005.91.00.00

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

🔍 Key Reminder:
- 4005 series (99/91) are for compounds (mixed with additives) but unvulcanized.
- 4002 series is for mixtures of natural and synthetic rubber.
- 4001 series is for raw/semi-raw natural rubber, not yet compounded.
- Do not confuse "raw rubber" (4001) with "rubber compound" (4002/4005).

👉 Consequence: Cannot determine natural vs. synthetic ratio → Audit Risk

❌ Mistake 4: Mixing raw rubber and compound in one shipment without separate declaration
👉 Consequence: Each item misclassified → Total Tariff Skyrockets!
