AI Analysis
🔬 Silicon Carbide Crystal Rods (SiC Rods)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy 📌 I. Product Definition & Classification: Do You Really Understand "SiC Rods"?
Silicon Carbide (SiC) crystal rods are high-performance ceramic materials known for their extreme hardness, high-temperature resistance, and thermal conductivity. In international trade, they are classified based on their physical state and specific application.
Two Main Categories:
1. Technical/Ceramic Rods (6909 Series): Rods used for industrial, laboratory, or technical applications (e.g., heating elements, abrasives, refractory supports). These are considered "articles of technical ceramics."
2. Primary Form Ingots/Blooms (2849 Series): Raw SiC blocks or rods in their primary, unprocessed form, intended for further chemical processing or as raw material for semiconductor substrates.
⚠️ Key Distinction Point: - If the rod is a finished technical product (shaped, polished, or designed for specific high-temp/corrosion resistance applications) → Classify under Chapter 69 (Ceramics). - If the rod is a raw primary form (ingot-like, crude, intended for slicing into wafers or chemical reduction) → Classify under Chapter 28 (Inorganic Chemicals).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Physical/Technical State |
|---|---|---|---|
6909.12.00.00 |
Ceramic goods of a kind used in laboratories, chemical, electrical, or industrial purposes | Technical ceramic rods, heating elements, refractory supports | ✅ Technical Ceramic: Finished shape, high hardness, specific industrial/lab use. |
6909.19.50.95 |
Other technical ceramic articles | SiC rods falling under "Other" category in Chapter 69 | ✅ Technical Ceramic: Broadly applicable "catch-all" for technical ceramics not specified elsewhere. |
2849.20.10.00 |
Silicon carbides | Primary form SiC rods/ingots | ✅ Primary Chemical Form: Raw material, unprocessed, intended for further processing. |
🔍 Critical Reminder: - "SiC Rods" are ambiguous. If the supplier describes them as "heating rods" or "abrasive rods," use 6909. - If described as "raw SiC crystal," "ingot," or "block," use 2849. - Do not mix these categories. Misclassification leads to massive duty discrepancies.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
✅ 1. Documentation Checklist (Mandatory)
| Document | Required? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state: Material (SiC), Form (Rod/Ingot), Dimensions, Purity %, and Intended Use (Lab? Heating? Raw Material?). |
| ✅ Product Photos | ✔️ | High-res images showing cross-section, surface finish, and packaging. Helps CBP distinguish between "finished rod" vs. "raw ingot." |
| ✅ Commercial Invoice | ✔️ | Must match HS Code. Use precise descriptions: "Silicon Carbide Technical Ceramic Rod" vs. "Silicon Carbide Raw Material." |
| ✅ Packing List | ✔️ | Detailed weight and volume breakdown. |
| ✅ Certificate of Origin | ✔️ | Proof of Chinese origin for duty calculation. |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Required for chemical handling and safety compliance. |
✅ 2. Declaration Strategy (Key Mnemonics)
🔥 “Know Your Form: Rod = Ceramic (39%), Ingot = Chemical (10%)!”
| Scenario | Correct HS Code | Common Mistake | Consequence |
|---|---|---|---|
| SiC Heating Element Rod | 6909.12.00.00 |
Declaring as 2849 |
Underpayment → Penalty + Back Taxes |
| SiC Rod for Lab Crucible | 6909.12.00.00 |
Declaring as 2849 |
Underpayment → Penalty + Back Taxes |
| Raw SiC Crystal Ingot/Rod | 2849.20.10.00 |
Declaring as 6909 |
Overpayment → Lost Profit |
| Polished SiC Wafer Pre-cursor | 2849.20.10.00 |
Declaring as 6909 |
Overpayment → Lost Profit |
✅ 3. Special Handling Tips
| Situation | Recommendation |
|---|---|
| OEM Custom Rods | Provide design specs. If they have specific tolerances for industrial use, lean toward 6909. |
| Mixed Shipments | Never mix 6909 and 2849 in one line item. Declare separately on the bill of lading. |
| "Silicon Carbide" Ambiguity | Add a note: "Product is a technical ceramic article for industrial use, not a primary chemical form." (for 6909). |
| High-Value Precision Rods | Consider applying for an Advance Ruling from US CBP to lock in the classification before shipment. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate (China Origin) | Notes |
|---|---|---|---|
| 🇺🇸 USA | 6909.12.00.00 |
39% | High tariff due to Section 301 & 122. |
| 🇨🇳 China | 6909.12.00.00 |
~4-9% | Lower export/import duties depending on trade agreement. |
| 🇪🇺 EU | 6909.12.00 |
4.0% | No Section 301 equivalent, but verify VAT/Duties. |
| 🇮🇳 India | 6909.12 |
7.5% - 10% | Check Basic Customs Duty (BCD) + SWS. |
| 🇻🇳 Vietnam | N/A (Transshipment) | Risk | Direct shipment from China may still face US duties if origin is not changed legitimately. |
📌 Conclusion: - USA is the most expensive market for SiC rods due to layered tariffs (39%). - Raw Material (
2849) is 29% cheaper in duties than Technical Ceramics (6909). - Optimization Strategy: If the product is a raw SiC rod for further processing, argue for 2849 to save 29%. If it is a finished technical part, accept 39% and build cost into the product price.
📌 VI. Common Errors & Pitfalls (Blood Lessons)
❌ Error 1: Declaring a finished SiC heating rod as Raw SiC Ingot (2849)
👉 Result: CBP inspects and classifies as 6909. You owe 29% more in back duties + penalties.
Prevention: Provide clear usage documentation proving it is a "technical ceramic article."
❌ Error 2: Declaring a raw SiC block as Technical Ceramic (6909)
👉 Result: You pay 39% instead of 10%. Overpaid $29,000 per $100,000 shipment.
Prevention: Provide manufacturer's statement that the product is "unprocessed primary form."
❌ Error 3: Ignoring Section 122 (10%) 👉 Result: Unexpected duty assessment at port. Prevention: Always budget for Section 122 in US imports from China.
✅ Correct Approach:
"Silicon Carbide Ceramic Rod, 200mm x 10mm, For Use in High-Temperature Furnace Heating Elements, Model XYZ, Made in China" → 6909.12.00.00 (39%) "Silicon Carbide Raw Crystal, Unprocessed Form, For Semiconductor Substrate Slicing, Model ABC, Made in China" → 2849.20.10.00 (10%)
🎯 VII. Conclusion: Professional Classification Saves Money!
🎯 Remember the Golden Rule:
🔹 "Finished & Technical = 6909 (39%)" 🔹 "Raw & Primary = 2849 (10%)" 🔹 "Don't guess! Provide specs! Save 29%!"
📌 Pro Tip: If your SiC rods are used in semiconductor manufacturing, verify if they qualify for any exclusions under the US-China trade war. Some advanced tech items may have different treatment. Always consult with a licensed customs broker.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
