🧪 High Purity Germanium Rod (HPGe)
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Germanium Rod"?
High Purity Germanium Rods are critical materials in the semiconductor, infrared optics, and solar energy industries. They are not just "metals"; they are highly refined functional materials. In international trade, they are categorized based on their form and purity.
Polycrystalline Germanium Rods (Polycrystalline): Multi-crystalline structures, typically used as feedstock for pulling single crystals or manufacturing solar cells.
Monocrystalline Germanium Rods (Monocrystalline): Single-crystal structure, primarily used for high-performance infrared lenses, fiber optics, and semiconductor detectors.
⚠️ Key Distinction Point:
- If the product is highly refined (>99.9999% purity) and in rod/bar form → Classified under Chapter 81 (Miscellaneous Metals), specifically 8112.
- If the product is already shaped into lenses or detectors (finished articles) → Classified under Chapter 90 (Optical/Scientific Instruments), specifically 9001 or 9031.
- Crucial Note: Raw rods, even if ultra-pure, remain under Chapter 81. Do not confuse them with finished optical components.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Purity/Form |
|---|---|---|---|
8112.99.10.00 |
Germanium, undeworked (includes rods, bars, wires, powder) | High-purity feedstock for semiconductors/infrared optics | ✅ Raw Rod/Bar |
8112.99.90.00 |
Other germanium, undeworked | Lower purity or non-standard forms of raw germanium | ✅ Raw/Unrefined |
9001.10.00.00 |
Optical fibers, bundles, etc. | Telecommunications, endoscopy (Made from Ge, but finished) | ❌ Finished Article |
9001.20.00.00 |
Lenses (including contact lenses), prisms | Infrared lenses, camera lenses (Made from Ge, but finished) | ❌ Finished Article |
2852.00.00.00 |
Germanium oxides, halogenides, etc. | Chemical precursors, powders, compounds | ❌ Chemical Compound |
🔍 Critical Reminder:
- High Purity Germanium (HPGe) Rods are classified under8112.99.10.00as "Germanium, undeworked."
- Do NOT classify them under Chapter 28 (Chemicals) unless they are in powder/oxide form. Rods are metallic products.
- If the rod is cut into wafers or polished into lenses, it moves to Chapter 90. Keep the classification aligned with the physical form at the time of import.
💰 III. 2026 Latest Tariff Rate Details (Including Surtax & Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Time: From November 10, 2025 (including subsequent imports)
🎯 1. 8112.99.10.00 —— Germanium, Undeworked (High Purity Rods)

| Base Tariff Rate | 0% (ad valorem) |
| USITC Surtax | +25% (Under USITC Footnote 9903.88.01, Section 301) |
| IEEPA Surtax | +10% (Targeting China/HK products, effective Nov 10, 2025) |
| Total Tariff Rate | 35% |
| Tax Calculation | CIF Value × 35% |
| De Minimis Exemption Eligible? | ❌ NO (deny_de_minimis) |
| Legal Basis Path | IEEPA:9903.01.25 → IEEPA:9903.01.24 → USITC:8112.99.10.00 → FOOTNOTE:9903.88.01 |
📌 Explanation:
- Germanium is a critical mineral and strategic material. The US imposes heavy tariffs to protect domestic supply chains and counter non-market practices.
- The 35% total rate (25% Section 301 + 10% IEEPA) is significant.
- No De Minimis Exemption: Even small shipments (e.g., <$800) are subject to these tariffs. This is a common trap for R&D samples.
🎯 2. Comparison: If Classified as "Chemical Precursor" (Incorrect but Potential Misunderstanding)
| Item | Content |
|---|---|
| HS Code | 2852.00.00.00 |
| Base Tariff | 0% |
| Surtax | +25% (Section 301) |
| IEEPA | +10% |
| Total | 35% |
| Risk | Misclassification can lead to penalties. However, the tariff rate is similar. The key is correct HS code for regulatory compliance (e.g., BIS checks). |
📌 Note:
- While the rate might seem similar, Germanium is subject to BIS (Bureau of Industry and Security) scrutiny. Incorrect HS codes may delay customs clearance for export control verification.
🛠️ IV. Customs Clearance Practical Advice (Field Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (Missing Items Will Cause Delays)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Certificate of Analysis (CoA) | ✔️ | Must specify purity (e.g., 6N, 7N), crystal structure (Mono/Polycrystalline), and form (Rod/Bar). |
| ✅ Product Specification Sheet | ✔️ | Detailed dimensions, weight, packaging method. |
| ✅ Commercial Invoice | ✔️ | Clearly state "High Purity Germanium Rod, Undeworked, for Semiconductor Use." |
| ✅ Packing List | ✔️ | Include net/gross weight, and ensure no mixed goods. |
| ✅ Export License (If Applicable) | ✔️ | Check if the origin requires export licenses; US importers must verify BIS compliance. |
| ✅ Bill of Lading/Air Waybill | ✔️ | Standard shipping document. |
✅ 2. Declaration Techniques (Key Mantra)
🔥 "Purity Matters, Form Defines, Don't Split, Declare Whole!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| High Purity Rod (Raw) | 8112.99.10.00 |
Misdeclare as "Electronic Component" → Delays |
| Germanium Powder | 2852.00.00.00 |
Misdeclare as "Rod" → Wrong HS Code |
| Finished Infrared Lens | 9001.20.00.00 |
Misdeclare as "Rod" → Undervaluation Risk |
| Mixed Shipment (Rod + Wafers) | Split HS Codes | Combine into one HS Code → Customs Rejection |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| Small R&D Sample (<$800) | ❌ Still Taxable! 35% applies. Do not rely on De Minimis. |
| Germanium from Vietnam/Malaysia | ✅ Potential Benefit: May avoid IEEPA surtax if proof of substantial transformation is provided. Check Rule of Origin carefully. |
| Export Control (BIS) | ⚠️ High Scrutiny: Germanium is on the Commerce Control List. Ensure end-user is legitimate and not on the Entity List. |
| Packaging Damage | 📦 Germanium is brittle. Ensure vacuum-sealed, shock-proof packaging. Damage may lead to "Condition of Goods" disputes. |

- USA is the most expensive market for Chinese-sourced Germanium due to 35% effective tariff.
- EU/Japan/Korea are more tariff-friendly, but require strict chemical/environmental compliance (REACH, etc.).
- Strategic Advice: For US imports, consider sourcing from non-China origins (e.g., Japan, South Korea, or recycled sources) to mitigate tariff risk.
📌 VI. Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Declaring "Germanium" as "Semiconductor Material" under Chapter 38
👉 Consequence: Customs will reclassify to Chapter 81, causing delays and potential penalties.
👉 Correct: Always use Chapter 81 for raw/metals.
❌ Error 2: Ignoring BIS (Bureau of Industry and Security) checks
👉 Consequence: Shipment held for "Export Control Review." Germanium is a strategic dual-use material.
👉 Correct: Provide end-user statements and ensure no sanctions violations.
❌ Error 3: Claiming De Minimis for small samples
👉 Consequence: 35% tax + penalties. The US explicitly denies De Minimis for Chinese goods under Section 301 and IEEPA.
👉 Correct: Budget for full tariff even for samples.
✅ Correct Declaration Example:
"High Purity Polycrystalline Germanium Rods, 99.9999% Pure, Undeworked, for Semiconductor Feedstock, HS Code 8112.99.10.00, Country of Origin: China"
🎯 VII. Conclusion: Precision Classification Saves Costs!
🎯 Remember the Mantra:
🔹 "Rods are Metals (Ch81), Lenses are Optics (Ch90). Don't confuse the two!"
🔹 "35% Tariff for US from China, Samples Not Exempt!"
🔹 "Check BIS, Check CoA, Clear Customs Fast!"
📌 Pro Tip:
If your Germanium rods are sourced from Japan, South Korea, or Europe, you can avoid the 10% IEEPA surtax and potentially the 25% Section 301 tax, bringing your total tariff to 0% (US) or very low rates.
Recommendation: Conduct a Pre-Ruling (Advance Ruling) with US CBP if importing large volumes to confirm classification and duty liability.
📣 Immediate Action:
📞 Consult a Customs Broker + Verify BIS Eligibility + Prepare CoA
🚀 Let your Germanium rods pass smoothly, avoid delays, and protect your margins!

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
