⛏️ Tungsten Concentrate (Tungsten Ore Processing Product)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 I. Product Definition & Classification: What Exactly is "Tungsten Concentrate"?
Tungsten Concentrate is a mineral product obtained from the processing of tungsten ores (such as wolframite or scheelite). It is NOT pure tungsten metal, nor is it finished tungsten products (like alloys or rods). It is an intermediate industrial raw material primarily used for smelting tungsten metal, producing tungsten carbide, or manufacturing high-performance alloys.
In international trade, classification hinges on the processing stage and chemical composition:
Tungsten Concentrate (W% > 55%): The primary exported form, usually consisting of tungsten trioxide (WO₃) or ammonium paratungstate (APT) intermediates, but strictly defined as "concentrated ore" under HS Chapter 26.
Tungsten Oxide (WO₃): If the concentrate has been chemically processed into pure oxide form, it may shift to Chapter 28.
Tungsten Metal/Alloys: Finished goods, classified under Chapter 81.
⚠️ Key Distinction:
- If the product is crushed/milled ore with high tungsten content but not chemically refined to pure oxide or metal → HS Code 2611.
- If the product is pure Tungsten Trioxide (WO₃) >99.9% purity, often used in battery or electronics supply chains → HS Code 2825 (though 2825 is for ammonia compounds, pure oxides often fall under 2825.90 or specific sub-headings depending on country interpretation, but strictly speaking, WO3 is often classified under 2825.90 or 2828? Correction: Pure Tungsten Oxide (WO3) is typically classified under HS Code 2825.90.00 (Other oxides, hydroxides, peroxides of tungsten) OR HS Code 2836? Clarification: According to WCO Explanatory Notes, Tungsten Oxide (WO3) is classified under 2825.90 or 2836.19? Actually, the most common and accurate HS for Tungsten Concentrate is 2611.00, and for Tungsten Oxide (WO3) it is 2825.90 or 2828? Let's stick to the most standard: Tungsten Concentrate = 2611.00.00.00. Tungsten Oxide (WO3) = 2825.90.00.00 (Other oxides).
- Critical Rule: Do not misdeclare concentrated ore as "Tungsten Powder" or "Tungsten Alloy" to avoid anti-dumping duties.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Chemical State |
|---|---|---|---|
2611.00.00.00 |
Tungsten Concentrates and Other Refractory Metal Ores and Concentrates | Raw exported material from mines; high-grade mineral concentrate; contains WO₃ but not pure chemical oxide | Mineral Concentrate |
2825.90.00.00 |
Other Oxides, Hydroxides and Peroxides, Whether or Not Chemically Defined | Pure Tungsten Trioxide (WO₃); chemical grade; used for battery cathodes or high-purity smelting | Chemical Oxide |
8101.91.00.00 |
Tungsten, Unworked or Worked but Not Fabricated; Powders: Tungsten in the Form of Slabs, Ingots, or Similar Basic Forms | Semi-finished metal products; not raw material | Metal |
8101.94.00.00 |
Tungsten, Unworked or Worked but Not Fabricated; Powders: Tungsten Powder | Fine metal powder; used for sintering, armor-piercing, or heavy alloys | Metal Powder |
🔍 Key Reminder:
- Tungsten Concentrate is strictly an ore/mineral product. If you ship "Tungsten Concentrate" but label it as "Tungsten Oxide," customs may reject it or apply a different duty rate.
- Chemical Purity: If the WO₃ content exceeds 95% and it is a pure chemical compound, consider 2825.90.00.00. If it is a physical concentrate from ore beneficiation, use 2611.00.00.00.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (None Missing)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Certificate of Analysis (COA) | ✔️ | Details WO₃ content, impurities (Sn, Bi, Mo, etc.). Crucial for classifying as Concentrate vs. Oxide. |
| ✅ Commercial Invoice | ✔️ | Clearly state "Tungsten Concentrate" or "Tungsten Trioxide," not generic "Minerals." |
| ✅ Packing List | ✔️ | Net/Gross weight, packaging type (e.g., 25kg bags). |
| ✅ Bill of Lading/Air Waybill | ✔️ | Standard shipping document. |
| ✅ Country of Origin Certificate (CO) | ✔️ | Must be issued by authorized body to prove Chinese origin. |
| ✅ Mineral Import Compliance Document | ✔️ | For US/EU, may require due diligence proof (conflict-free, environmental). |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Concentrate is Ore, Oxide is Chem, Don't Mix, Or Pay the Price!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| High-grade mineral powder | 2611.00.00.00 |
Declared as "Tungsten Powder" → 8101 → 35% + Anti-Dumping |
| Pure WO₃ chemical | 2825.90.00.00 |
Declared as "Ore" → 2611 → Potential misclassification penalty |
| Tungsten Alloy | 8101.xxxx.xxxx |
Declared as "Concentrate" → 35% + 100%+ Anti-Dumping |
| Tungsten Carbide | 8113.00.00.00 |
Declared as "Concentrate" → 35% + High Anti-Dumping |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| Mixed Purity | If WO₃ is 60%, declare as Concentrate (2611). If >95% pure, consider Oxide (2825). Check COA. |
| Transshipment | If shipped via Vietnam/Malaysia, ensure no substantial transformation. If not, still Chinese origin → 35% + possible circumvention penalties. |
| Strategic Stockpile | US DoD or private entities may apply for Exclusions. Check USITC exclusion lists for 2611/2825. |
| Anti-Dumping | Check if your specific exporter is subject to AD/CVD orders. Some Chinese tungsten exporters face 200%+ AD. |

📌 VI. Common Mistakes & Pitfall Guide (Blood-Tears Lesson)
❌ Mistake 1: Declaring "Tungsten Concentrate" as "Tungsten Metal"
👉 Consequence: Anti-Dumping Duty (AD) can exceed 200%. Customs will reject due to mismatched HS code and high risk.
❌ Mistake 2: Ignoring Impurity Content in COA
👉 Consequence: If Bi, Sn, or Mo content is high, it may be classified differently or trigger environmental scrutiny.
❌ Mistake 3: Transshipping via Third Countries Without Value Addition
👉 Consequence: Circumvention Investigation. If no substantial transformation occurs, customs will still apply Chinese origin rates + penalties.
❌ Mistake 4: Using Vague Descriptions like "Mineral Powder"
👉 Consequence: Customs will request detailed COA and may classify under the highest duty rate or detain for inspection.
✅ Correct Practice:
"Tungsten Concentrate, WO₃ 65%, Bi <0.1%, Sn <0.1%, in 25kg PP bags, Origin: China, HS 2611.00.00.00"
🎯 VII. Conclusion: Precise Classification, Smooth Clearance, Cost Optimization!
🎯 Remember the Mantra:
🔹 "Concentrate is Ore, Oxide is Chem, Don't Mix, Or Pay the Price!"

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
