🖨️ Cassiterite Ore (Tin Ore)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Cassiterite"?

Cassiterite (Stannic Oxide, $SnO_2$) is the primary ore of tin. In international trade, it is strictly categorized based on its physical form: whether it is raw, unprocessed ore or refined concentrate. This distinction is critical because the taxation structure differs significantly between raw materials and processed concentrates.

Raw Tungsten/Tin Ores: Natural mineral formations that have undergone minimal processing (e.g., washing, simple gravity separation) but are not yet ready for direct metallurgical smelting.

Concentrates: Processed materials where the tin content has been significantly increased through crushing, grinding, and separation techniques, making them ready for industrial extraction.

⚠️ Key Distinction Point:
- If the product is raw ore (natural state, low tin %), it falls under 2611.00.30.00.
- If the product is concentrate (high tin %, processed), it falls under 2611.00.60.00.

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

🔍 Important Reminder:
- Raw Ores (2611.00.30.00) are subject to 0% tariff. This encourages the import of raw materials for domestic processing.
- Concentrates (2611.00.60.00) are subject to a specific duty (37.5¢/kg) PLUS a 25% ad valorem surcharge. This protects domestic processing industries by making imported concentrates more expensive.
- Ensure your commercial invoice clearly states whether the goods are "Ore" or "Concentrate" to avoid misclassification penalties.

💰 III. 2026 Latest Tariff Rate Details (Including Surcharges & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN) (Note: Tariffs may vary by origin, but these are the general US rates provided in data)
✅ Effective Time: Current 2026 Tariff Schedule

🎯 1. 2611.00.30.00 —— Cassiterite Ores (Raw)

📌 Explanation:
- Raw ores are considered low-value-added inputs. The US maintains a 0% tariff to ensure a steady supply of raw materials for domestic manufacturing and strategic reserves.
- No additional Section 301 or IEEPA surcharges apply to raw ores.

🎯 2. 2611.00.60.00 —— Cassiterite Concentrates (Processed)

📌 Important Note:
- The tax structure is mixed: It includes a specific duty (based on weight/content) AND an ad valorem duty (percentage of value).
- The 25% surcharge is a significant penalty for importing processed concentrates, likely due to trade restrictions or protective tariffs.
- Calculation Example:
- If you import 1,000 kg of concentrate valued at $10,000:
- Specific Duty: 1,000 kg × $0.375 = $375
- Ad Valorem Duty: $10,000 × 25% = $2,500
- Total Tax: $2,875 (28.75% effective rate on value, plus per-kg cost).

🌍 V. Global Market Clearance Comparison (2026 Latest)

📌 Conclusion:
- The US is the only market with a significant 25% surcharge on concentrates.
- Raw Ores are universally treated with lower tariffs to encourage raw material supply.
- Accurate classification is paramount. Misdeclaring concentrate as ore can lead to severe penalties.

📌 VI. Common Errors & Pitfall Guide (Blood & Tears Lessons)

❌ Error 1: Declaring "Concentrate" as "Ore" to avoid the 25% surcharge.
👉 Consequence: Customs lab test reveals high tin content → Back taxes, fines, and potential blacklisting.

❌ Error 2: Ignoring the specific duty (37.5¢/kg) for concentrates.
👉 Consequence: Budgeting only for ad valorem tax → Cash flow shortfall at customs clearance.

❌ Error 3: Providing inaccurate weight or tin content.
👉 Consequence: Customs uses default values (usually higher) for duty calculation → Overpayment or dispute delays.

❌ Error 4: Using generic descriptions like "Mineral Concentrate."
👉 Consequence: Customs cannot determine HS code → Shipment held for inspection.

✅ Correct Practice:

"Cassiterite Concentrate, Tin Content: 60%, Net Weight: 50,000 kg, Origin: China, HS Code: 2611.00.60.00"

🎯 VII. Conclusion: Precise Classification Saves Money!

🎯 Remember the Mantra:

🔹 "Ore is Free, Concentrate is Fee!"
🔹 "Weight Determines the Specific Duty, Value Determines the Percentage!"
🔹 "Declare Accurately, or Pay Double!"

📌 Pro Tip:
If you are importing concentrates, consider whether you can source raw ores instead (if available) to save the 25% surcharge, provided your smelting facility can handle lower-grade inputs.
Always request a Certificate of Analysis (COA) from the supplier to verify tin content for accurate duty calculation.
