⚛️ Silicon Nitride Target (Si₃N₄ Target)
🌐 HS Code Classification & Customs Clearance Guide | 2026 Tariff Analysis | Critical Raw Material Strategy
📌 I. Product Definition: What is a "Silicon Nitride Target"?
A Silicon Nitride Target is a high-purity ceramic material used primarily in Physical Vapor Deposition (PVD) and Sputtering processes. It is not a finished electronic component but a raw material/semi-finished good used to coat other substrates with silicon nitride films.
In international trade, it is classified based on its chemical composition (inorganic compound) and its form (raw material/target for coating).
⚠️ Critical Distinction:
- It is NOT a finished semiconductor device or chip (which would fall under Chapter 85).
- It IS a chemical raw material or an inorganic compound in a semi-finished shape.
- Misclassification as a "chemical catalyst" vs. "inorganic compound" drastically changes the tax rate.
📦 II. HS Code Classification Details (2026 Latest Tariff Schedule)
Based on the provided data, there are 4 possible HS Codes depending on how customs authorities interpret the "functional purpose" vs. "chemical nature" of the target.
| HS Code | Product Description | Classification Logic | Total Tax Rate |
|---|---|---|---|
3815.90.50.00 |
Reaction Accelerators/Catalysts (Other) | Viewed as a chemical agent (accelerator/catalyst) for industrial processes. Treated as a chemical preparation rather than a pure compound. | 40.0% |
3815.90.30.00 |
Reaction Accelerators/Catalysts (Inorganic) | Viewed as an inorganic chemical used in reactions. Fits the "completely inorganic" and "catalytic/accelerator" criteria. | 35.0% |
2853.90.90.90 |
Other Inorganic Compounds | Viewed strictly as an inorganic compound (Silicon Nitride is Si₃N₄). The "target" form is considered a primary shape of the compound. | 37.8% |
2853.90.50.00 |
Other Phosphides (Non-Metallic) | Controversial Match. Argues that Si₃N₄ is a "non-metallic nitride" and fits loosely into "non-metallic phosphides/nitrides" categories. Riskier classification. | 35.0% |
🔍 Key Insight:
- The lowest base duty is 0% (for3815.90.30.00and2853.90.50.00), but additional surcharges apply.
- The highest total tax is 40% (3815.90.50.00).
- Customs Preference: Customs often prefer2853(Chemical Section) for pure compounds over3815(Miscellaneous Chemical Products) unless the product is explicitly formulated as a catalyst.

🛠️ IV. Customs Clearance Practical Advice
✅ 1. Required Documentation Checklist
| Document | Mandatory? | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must state: Silicon Nitride (Si₃N₄), Purity % (>99%), Density, Form (Target/Wafer) |
| ✅ Certificate of Analysis (CoA) | ✔️ | Proves chemical composition is pure Si₃N₄ |
| ✅ Intended Use Statement | ✔️ | "Used in PVD Sputtering Process for Film Deposition" |
| ✅ Commercial Invoice | ✔️ | Clearly describe as "Silicon Nitride Target, Ceramic Raw Material" |
| ✅ HS Code Pre-Ruling | ✔️ | Highly Recommended due to multiple classification options |
| ✅ Photos of Product | ✔️ | Show shape, markings, and packaging |
✅ 2. Declaration Strategy & Tricks
🔥 "Pure Compound vs. Catalyst: Choose Wisely!"
| Scenario | Recommended HS Code | Reason |
|---|---|---|
| Pure Si₃N₄ Ceramic Target | 2853.90.90.90 |
Technically accurate as an inorganic compound. Safer against audits. |
| Target with Added Binders/Additives | 3815.90.50.00 |
If mixed with other chemicals, it becomes a "preparation." |
| Aggressive Cost Minimization | 3815.90.30.00 |
Lower base duty (0%). Requires strong argument for "inorganic catalyst" role. |
| Avoid | 2853.90.50.00 |
"Phosphide" misclassification is easily challenged by customs. |
📌 Pro Tip:
- Always declare the chemical name (Si₃N₄) and HS Code together.
- Do NOT use vague terms like "Ceramic Piece" or "Electronic Component."
- If asked, emphasize that it is a "Raw Material for Semiconductor Manufacturing," not a finished good.
✅ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Targets | Provide custom design drawings. Clarify that shape does not change chemical classification. |
| Mixed Shipments (Si₃N₄ + SiC) | Split declarations. SiC (Silicon Carbide) may have different HS codes. Do not mix unless both are under the same code. |
| Small Samples | Still subject to tariffs. De Minimis ($800) does NOT apply to Section 301/IEEPA goods. |
| Transshipment via Vietnam/Mexico | Risky. If origin is China, tariffs still apply. Avoid false labeling. |

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
