⚛️ 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.

- Warning: Customs may reject this if they strictly enforce "Phosphide" vs. "Nitride." Use only with strong legal justification or pre-ruling.
🛠️ 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. |
🌍 V. Global Market Comparison (2026)
| Country | Recommended HS Code | Est. Tariff (China Origin) | Notes |
|---|---|---|---|

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
