🔩 Road Sign Screw (Highway Fasteners)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Truly Understand "Road Sign Screws"?
Road sign screws are critical hardware components used in transportation infrastructure. They are specifically designed to secure traffic signs, guardrails, and street lighting fixtures to posts or bases. In international trade, they are generally classified under Chapter 73 (Articles of Iron or Steel) or Chapter 84/87 (Parts of Vehicles/General Hardware), depending on their specific design and whether they are considered "parts" or "general fasteners."
Key Distinctions: General Purpose Steel Screws: Standard hex bolts, self-tapping screws, or lag screws made of iron or steel, used for securing signs to metal/wood posts. These fall under Chapter 73. Specialized Vehicle Parts: If the screw is specifically designed as an integral part of a vehicle’s lighting system or signaling device (e.g., internal mounting screws for a signal light cluster), it might be classified as a part under Chapter 87. However, for external road signs, Chapter 73 is the standard.
⚠️ Critical Classification Point:
- If the item is a standard fastener (bolt, screw, nut, washer) made of iron/steel → HS 7318.
- If the item is a specialized sensor/mounting bracket with integrated electronics → HS 9031 or 8543 (Rare for simple "screws").
- Most road sign screws are classified under 7318.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Material/Type |
|---|---|---|---|
7318.15.50.00 |
Other screws and bolts, whether or not with their nuts or washers, of iron or steel | Standard hex head screws, carriage bolts for sign posts | ✅ Iron/Steel |
7318.16.00.00 |
Nuts of iron or steel | Often shipped with screws; classified separately if not attached | ✅ Iron/Steel |
7318.15.00.00 |
Other screws and bolts, of iron or steel | General purpose machine screws, self-tapping screws for metal signs | ✅ Iron/Steel |
7318.22.00.00 |
Other springs and spring washers, of iron or steel | Spring washers often included in road sign kits | ✅ Iron/Steel |
8708.29.90.00 |
Other parts and accessories of motor vehicles | Only if specifically identified as a part of a vehicle's signaling system (unlikely for external signs) | ❌ Part of Vehicle |
8471.80.00.00 |
Other units of automatic data processing machines | Incorrect. Do not classify hardware as IT equipment. | ❌ Wrong |
🔍 Key Reminder:
- Standard road sign screws are almost always7318.15or7318.16.
- Do not classify them under vehicle parts (8708) unless they are internal components of the vehicle itself (e.g., a bolt holding a license plate light inside the car). For external road signs, Chapter 73 is correct.
- If the screw is made of aluminum or stainless steel, the chapter remains 73, but the subheading may vary slightly based on alloy composition (usually still within 7318).
💰 III. 2026 Latest Tariff Rate Details (Including Additional Taxes, Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: November 10, 2025 (and subsequent imports)
🎯 1. 7318.15.50.00 —— Screws/Bolts of Iron or Steel (Standard)
| Item | Content |
|---|---|
| Base Tariff Rate | 5.6% (ad valorem) |
| USITC Additional Tax | +25% (Under USITC Footnote 9903.73.18.15) |
| IEEPA Additional Tax | +10% (For China/HK products, effective from Nov 10, 2025) |
| Total Tariff Rate | 40.6% |
| Tax Calculation | CIF Value × 40.6% |
| De Minimis Exemption | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | IEEPA:9903.01.25 → IEEPA:9903.01.24 → USITC:7318.15.50.00 → FOOTNOTE:9903.73.18.15 |
📌 Explanation:
- The 25% USITC tax is part of the Section 301 tariffs on Chinese steel products.
- The 10% IEEPA tax is the additional tariff imposed on Chinese goods starting Nov 10, 2025.
- Total 40.6% is a high barrier. Many importers avoid direct entry of Chinese steel fasteners due to cost.
🎯 2. 7318.15.00.00 —— Other Screws and Bolts (General)
| Item | Content |
|---|---|
| Base Tariff Rate | 5.6% |
| USITC Additional Tax | +25% |
| IEEPA Additional Tax | +10% |
| Total Tariff Rate | 40.6% |
| Tax Calculation | CIF × 40.6% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis Path | IEEPA:9901.25 → IEEPA:9903.01.24 → USITC:7318.15.00.00 → FOOTNOTE:9903.73.18.15 |
📌 Note:
- Same rate as above. Most "road sign screws" fall into this general category if they are not hex bolts specifically.
- Even if the screw is stainless steel, if it is of iron/steel origin (China), the tariff applies.
🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documentation Checklist (Mandatory)
| Document | Required | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Material (e.g., ASTM A307, A193), Thread Size, Length, Head Type |
| ✅ Material Certificate (Mill Cert) | ✔️ | Proves steel composition and origin. Crucial for USITC classification. |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Road Sign Screws" or "Steel Bolts", not vague "Hardware" |
| ✅ Packing List | ✔️ | Detailed weight and count. Steel is heavy; weight accuracy is vital for duty calculation. |
| ✅ Country of Origin Certificate | ✔️ | If not China, may qualify for lower rates (e.g., Vietnam, Mexico). |
| ✅ FCC/CE Certs | ❌ | Not required for steel screws (no electronics). |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Material is Steel, Chapter 73, Don't Call it Vehicle Parts, 40% Will Hurt!"
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Standard Hex Bolt | 7318.15.50.00 "Hex Bolts, Steel" |
Misclassifying as "Vehicle Part" → 0% base but audit risk + penalty |
| Self-Tapping Screw | 7318.15.00.00 "Self-Tapping Screws, Steel" |
Calling it "Sign Hardware" → Vague, leads to delay |
| Stainless Steel Screw | 7318.15.50.00 (if steel grade) |
Assuming "Stainless" means no tariff → Still 40.6% if from China |
| Set of Screws+Nuts+Washers | Declare separately or as kit under 7318.15/16 | Splitting incorrectly → May trigger different duty rates per item |
✅ 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Road Signs | If screws are proprietary and unique, still classify under 7318 unless they are electronic connectors. |
| Pre-assembled Sign Kits | If screws are pre-installed, declare the sign (8708 or 7326) and the screws may be absorbed. However, CBP often requires separate declaration for value allocation. |
| Aluminum Screws | If made of aluminum (not steel), check Chapter 76. USITC tariffs on steel may not apply, but IEEPA may still apply. Check HS 7618. |
| Zinc-Plated Screws | Coating does not change Chapter 73 classification. Still 7318. |
🌍 V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 7318.15.50.00 |
40.6% (5.6% + 25% + 10%) | None | High tariff; consider non-China origin. |
| 🇨🇳 China | 7318.15.50.00 |
5% | None | Low import duty for domestic consumption. |
| 🇪🇺 EU | 7318.15.00.00 |
6.5% (Most Favored Nation) | REACH (if coated) | No Section 301 equivalent, but anti-dumping may apply. |
| 🇦🇺 Australia | 7318.15.00.00 |
5% | None | Standard MFN rate. |
| 🇯🇵 Japan | 7318.15.00.00 |
0-3.5% | None | Low tariff; JIS standards may apply. |
📌 Conclusion:
- USA is the most challenging market for Chinese steel fasteners due to the 40.6% combined tariff.
- EU and Asia offer much lower barriers (5-6.5%).
- Strategy: For US market, consider sourcing screws from Vietnam, Thailand, or Mexico to mitigate tariffs, or use non-China origin steel.
📌 VI. Common Errors & Pitfalls (Blood & Tears Lessons)
❌ Error 1: Classifying steel screws under 8708 (Vehicle Parts)
👉 Consequence: CBP may reject the declaration, issue a penalty, and reassess under 7318 + retroactive duties.
❌ Error 2: Ignoring "Country of Origin" for IEEPA
👉 Consequence: If declared as "Made in USA" but sourced from China, it’s fraud. Heavy penalties.
❌ Error 3: Vague Description "Hardware"
👉 Consequence: Customs holds shipment for inspection, causing delays and storage fees.
❌ Error 4: Assuming "Stainless" Means Tariff-Free
👉 Consequence: Stainless steel screws from China still face 40.6% if classified under 7318 and subject to IEEPA.
✅ Correct Practice:
"Steel Hex Bolts, Zinc-Plated, ASTM A307 Grade B, Length 3", Origin: China, HS 7318.15.50.00"
🎯 VII. Conclusion: Professional Declaration Saves Money!
🎯 Remember:
🔹 "Steel Screws, Chapter 73, US Tariff 40.6%, Think Twice!"
🔹 "IEEPA 10% + USITC 25% = High Cost, Source Smartly!"
📌 Tip:
If your road sign screws are originating from Vietnam, Mexico, or Malaysia, you may qualify for IEEPA exemption or lower USITC rates.
Consider Advance Ruling for large shipments to ensure correct classification.

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
