🔩 Tension Springs (Tension Springs for Mechanical Applications)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Tension Springs"?
Tension springs, also known as extension springs, are helical coils that resist pulling forces. They are ubiquitous in automotive suspensions, industrial machinery, household appliances, and hardware (e.g., garage doors, trampolines). In international trade, the classification hinges primarily on material and function/destination.
Two Main Classification Paths: 1. Article 73 (Articles of Iron or Steel): The most common path. Applies to general-purpose metal springs where the material (iron/steel) is the defining characteristic. 2. Article 91 (Watches and Clocks and Parts Thereof): A specialized path. Applies only if the spring is a specific component for timekeeping instruments, such as a balance spring (hairspring) or a mainspring.
⚠️ Critical Distinction:
- If it is a general mechanical spring (steel/iron) → Go to Chapter 73.
- If it is a precision spiral spring for a watch/clock → Go to Chapter 91.
- Note: Many users misclassify general steel springs under Chapter 91 due to the word "spring," leading to massive tariff discrepancies.
📦 II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
Based on the provided data, here are the four specific HS Codes and their logical derivation:
| HS Code | Product Description & Logic | Key Characteristic | Conflict Check |
|---|---|---|---|
7320.10.60.15 |
Other Springs, of Iron or Steel Matches material (Iron/Steel) and form (Spring). No obvious material conflict. |
General Industrial/Automotive Steel Spring | ❌ No Conflict |
7320.20.10.00 |
Leaf Springs and Leaves for Springs, of Iron or Steel Matches material (Iron/Steel) and form (Spring). Usage description missing but no material conflict. |
Leaf-style or flat steel springs | ❌ No Conflict |
9114.90.38.00 |
Parts of Watches/Clocks: Springs (including Balance Hairsprings) Product name matches "Springs (including balance hairsprings)" in classification explanation perfectly. No material conflict. |
Precision Watch/Clock Hairsprings | ❌ No Conflict |
9114.90.34.00 |
Parts of Watches/Clocks: Springs (including Hairsprings) Based on consistent usage with "Springs (including hairsprings)." No material or form conflict. |
Precision Watch/Clock Mainsprings/Balance Springs | ❌ No Conflict |
🔍 Key Reminder:
- Chapter 73 Codes (7320.10...&7320.20...) are for standard industrial/commercial tension springs. They are subject to heavy additional tariffs.
- Chapter 91 Codes (9114.90...) are for horological (watchmaking) springs. If your product is a regular tension spring, DO NOT use these codes. If you misdeclare a regular steel spring as a watch part, you may face penalties. Conversely, declaring a watch part as a general spring might delay customs for further inspection.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Explanation |
|---|---|---|
| ✅ Product Spec Sheet | ✔️ | Must specify material (e.g., "Carbon Steel 65Mn"), dimensions, load rating, and intended use. |
| ✅ Photos (Clear Labeling) | ✔️ | Show the spring type (helical, leaf, etc.). If for watches, show scale/microscopic view if possible. |
| ✅ Commercial Invoice | ✔️ | Description must be precise: "Steel Tension Spring for Automotive Use" vs "Watch Balance Hairspring." |
| ✅ Certificate of Origin (CO) | ✔️ | Proof of China origin triggers Section 122 and 301. |
| ✅ Material Declaration | ✔️ | Explicitly state "Iron or Steel." If Alloy, specify. |
✅ 2. Declaration Strategy (Key Mantra)
🔥 "Material First, Function Second, Chapter 91 is for Watches Only!"
| Scenario | Correct HS Code | Wrong Code | Consequence |
|---|---|---|---|
| Standard Steel Tension Spring (e.g., for garage door, machine) | 7320.10.60.15 |
9114.90.38.00 |
Audit Risk: Customs will reclassify to Ch 73, charge 88.2%, plus penalties. |
| Leaf Spring / Flat Steel Spring | 7320.20.10.00 |
7320.10.60.15 |
Minor risk, but ensure description matches "Leaf" vs "Coil." |
| Watch Balance Hairspring | 9114.90.38.00 |
7320.10.60.15 |
Overpaying tax (21.7% vs 88.2%). If clearly identifiable, use Ch 91. |
| Watch Mainspring | 9114.90.34.00 |
7320.10.60.15 |
Overpaying tax (24.8% vs 88.2%). |
✅ 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| Mixed Packaging | If shipping both watch springs and general springs, declare separately. Do not mix in one line item to avoid audit flagging. |
| Stainless Steel Springs | If made of stainless steel, verify if Section 122 applies. Section 122 typically targets "Steel, Aluminum, and Copper Products." Check if stainless is included in the specific Section 122 definition for your shipment. Data implies it applies, but verify locally. |
| OEM Custom Springs | Provide customer design files. If the design is specific to a watch movement (e.g., fits into a specific caliber), use Chapter 91 codes with technical proof. |
| High Value Watch Springs | Even though tax is lower (24.8%), ensure the value is declared accurately. Watch parts are often high-value per gram. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate (China Origin) | Certification/Notes |
|---|---|---|---|
| 🇺🇸 USA | 7320.10.60.15 |
88.2% | Section 301 + 122. Very High. |
| 🇪🇺 EU | 7320.20.80 (Est.) |
~4.5% | No Section 122/301. Standard MFN rate. |
| 🇨🇳 China | 7320.10.60.15 |
~6-7% | Standard Import Tariff. |

📌 Conclusion:
- The USA is the most expensive market for steel tension springs due to Section 122 (50%) and 301 (25%).
- Cost Saving Strategy: If the product is indeed a watch part, use9114.90.34.00or9114.90.38.00to reduce tax from ~88% to ~22%.
- Risk Management: If it is a general spring, do not try to hide it under Chapter 91. The risk of 88.2% tax + penalties is not worth the 22% saving if caught.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Declaring a heavy-duty steel extension spring (for a car or door) as a "Watch Spring" to save tax.
👉 Consequence: Customs inspector sees a 10cm long, 1cm thick steel coil. Rejects Ch 91. Reclassifies to 7320.10.60.15. Bill for 88.2% tax + fines.
❌ Error 2: Using 7320.20.10.00 for a helical coil spring.
👉 Consequence: Mismatch between description ("Coil Spring") and Code (often "Leaf Springs"). May trigger manual review, causing 2-4 week delays. Use 7320.10.60.15 for coils.
❌ Error 3: Ignoring Section 122.
👉 Consequence: Assuming only 301 (25%) applies. Missing the 50% Section 122 surcharge for steel/aluminum products. Underpayment by 50%.
✅ Correct Practice:
"Steel Tension Spring, Carbon Steel, 100mm Length, 50N Force, for Industrial Machinery Use" →
7320.10.60.15
"Watch Balance Hairspring, Stainless Steel, 0.05mm Thickness, for Horological Use" →9114.90.38.00
🎯 VII. Conclusion: Precise Classification Saves Thousands
🎯 Remember the Mantra:
🔹 "Steel General Spring = Ch 73 (88.2%)!"
🔹 "Watch Hairspring = Ch 91 (21.7%)!"
🔹 "Misclassification = Audit + Penalty + Delay!"
📌 Pro Tip:
If you are unsure whether a spring qualifies as a "watch part," submit an Application for Advance Ruling (AR) to US Customs and Border Protection (CBP) before shipping. The small fee for an AR is negligible compared to the potential 66% tax difference.

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
