🛡️ Heat Shields (Thermal Protection Systems)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Know "Heat Shields"?
Heat shields are critical thermal protection components used in aerospace, automotive, industrial manufacturing, and consumer electronics to manage high temperatures, prevent heat transfer, and protect sensitive components. In international trade, they are categorized based on their raw material composition and manufacturing process.
Key Material Distinctions: 1. Mica-Based (云母制品): Natural or synthetic mica sheets/plates; excellent electrical insulation and heat resistance. 2. Glass Fiber/Cotton (玻璃纤维/玻璃棉): Fibrous materials used for bulk insulation; lightweight and flexible. 3. Plastic/Polymer-Based (塑料/其他材料): Resin-bound or composite materials; often used for precision-molded parts.
⚠️ Critical Classification Point:
- If the product is made from mica → Look at Chapter 68 (HS 6814.xx).
- If the product is made from glass fiber/cotton → Look at Chapter 70 (HS 7019.xx).
- If the product is made from plastic/polymers → Look at Chapter 39 (HS 3926.90.99).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Material Type |
|---|---|---|---|
6814.10.00.00 |
Mica products, suitable for heat shields | High-temp industrial ovens, aerospace insulation | ✅ Mica |
7019.80.90.00 |
Other glass wool and its products, suitable for heat shields | Automotive exhaust wraps, pipe insulation | ✅ Glass Fiber |
3926.90.99.89 |
Other articles of plastics and other materials, suitable for heat shields | Custom-molded engine covers, electronic device shields | ✅ Plastic/Composite |
6814.90.00.00 |
Other mica products, suitable for heat shields | Mica tape, paper, or non-sheet forms | ✅ Mica |
7019.90.51.50 |
Other glass fiber products, suitable for heat shields | Glass fiber mats, blankets, or woven fabrics | ✅ Glass Fiber |
🔍 Key Reminder:
- The material is the primary determinant for classification. A "heat shield" made of different materials falls into entirely different chapters. - Even if the function is identical (heat protection), the material dictates the HS Code. - Ensure the commercial invoice clearly states the material (e.g., "Mica Insulation Plate" vs. "Glass Fiber Blanket") to avoid misclassification.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Additions)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: 2025+ (Current Tariff Regime)
🎯 1. 6814.10.00.00 —— Mica Products (Heat Shields)
| Item | Content |
|---|---|
| Base Tariff | 2.7% |
| Section 301 Surtax | +25.0% |
| Section 122 Duties | +10.0% |
| Total Tax Rate | 37.7% |

| De Minimis Eligibility | ❌ Not Eligible |
| Legal Basis Path | Section 301: 6814.10.00 → Section 122: 6814.10.00 |
📌 Explanation:
- The 25% is the standard Section 301 tariff on Chinese goods under HTS 6814. - The 10% is an additional Section 122 duty (often applied to specific strategic materials or during trade enforcement periods). - Total Cost Impact: High. Producers should consider value-added processing abroad to mitigate this.
🎯 2. 7019.80.90.00 —— Other Glass Wool Products (Heat Shields)
| Item | Content |
|---|---|
| Base Tariff | 4.3% |
| Section 301 Surtax | +25.0% |
| Section 122 Duties | +10.0% |

🛠️ IV. Customs Clearance Operational Advice (Practical Pitfall Avoidance)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify material composition (e.g., "90% Mica, 10% Silicone Binder"). |
| ✅ Material Composition Statement | ✔️ | Critical for HS Code validation.海关 needs to verify if it's mica, glass, or plastic. |
| ✅ Product Photos | ✔️ | Clear images showing texture, thickness, and any branding/model numbers. |
| ✅ Commercial Invoice | ✔️ | Must match the HS Code description exactly (e.g., "Mica Heat Insulation Sheet"). |
| ✅ Packing List | ✔️ | Include net/gross weight, dimensions, and package count. |
| ✅ Certificate of Origin | ✔️ | Required for Section 301/122 duty assessment. |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Material First, Function Second; Name Accurate, Rate Accurate!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Mica Heat Shield | 6814.10.00.00 "Mica Plates for Heat Insulation" |
Call it "Heat Insulator" → Risk of general 301 rate |
| Glass Fiber Wrap | 7019.80.90.00 "Glass Wool for Heat Shielding" |
Call it "Fabric" → Misclassification penalty |
| Plastic Composite Shield | 3926.90.99.89 "Plastic Heat Shield, Model XYZ" |
Call it "Metal Part" → Wrong Chapter |
| Mixed Material | Declare primary material | Hide material content → Audit failure |
✅ 3. Special Handling Cases
| Scenario | Handling Advice |
|---|---|
| OEM Custom Parts | Provide engineering drawings showing material layers. |
| Sample Shipments | Declare as "Sample" but still pay duties if value exceeds de minimis (unlikely for these codes). |
| Assembly in 3rd Country | If processed significantly in Vietnam/Mexico, may qualify for preferential rates (check USMCA/ASEAN rules). |
| Dual-Use Items | If used in aerospace/defense, ensure no ITAR/EAR restrictions apply. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3926.90.99.89 (Best) |
22.8% (Plastic) | FCC/UL (if electrical) | Mica/Glass face 37-39% |
| 🇺🇸 USA | 6814.10.00.00 (Mica) |
37.7% | N/A | High duty burden |
| 🇺🇸 USA | 7019.80.90.00 (Glass) |
39.3% | N/A | Highest duty burden |
| 🇨🇳 China | Same HS Codes | 5-10% (Import Duty) | CCC (if applicable) | Lower base tariffs |
| 🇪🇺 EU | Various (Chapter 39/68/70) | 0-4.5% (Standard) | CE/RoHS | No Section 301/122 equivalents |
| 🇯🇵 Japan | Various | 0-5% | PSE/MLIT | Competitive market |
📌 Conclusion:
- The US is the only market with punitive surtaxes (301 + 122) on these Chinese-made heat shield materials. - Plastic-based heat shields (3926) offer the lowest duty cost (22.8%) compared to Mica (37.7%) or Glass (39.3%). - EU and Asia markets remain tariff-free or low-tariff, making them more competitive for export.
📌 VI. Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Classifying all heat shields under one generic code.
👉 Consequence: Misclassification penalties + back duties. Each material has a distinct HS Code.
❌ Error 2: Under-declaring material content.
👉 Consequence: Customs may reclassify based on sample analysis, imposing higher tariffs.
❌ Error 3: Ignoring Section 122 Duties.
👉 Consequence: Unexpected 10% surtax at border, causing delays and cash flow issues.
❌ Error 4: Not specifying "Heat Shield" in description.
👉 Consequence: Customs may view it as a generic part, leading to additional scrutiny.
✅ Correct Practice:
"Mica Heat Shield Plate, 1mm Thick, Industrial Grade, Part No. HS-100, Made in China"
vs.
"Insulation Material" (Too vague)
🎯 VII. Conclusion: Precision Classification for Cost Efficiency
🎯 Remember the Mantra:
🔹 "Plastic is Cheapest (22.8%), Glass is Most Expensive (39.3%)"
🔹 "Material Dictates Code, Code Dictates Cost"
🔹 "Section 301 + 122 = High Duty, Plan Ahead!"
📌 Pro Tip:
If your heat shield can be engineered as a plastic composite rather than mica or glass, you can save ~15% in duties. Consult with engineering teams to optimize material selection for cost-efficiency without compromising performance.
📣 Immediate Action:
📞 Engage a licensed customs broker + Provide material specs + Apply for Advance Ruling if volume is high.
🚀 Optimize your supply chain for smooth clearance, reduced costs, and maximum profit.
✨ Professional Clearance Starts with Precise Classification!
💼 Every Dollar Saved in Duties is Pure Profit!

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
