🏭 Micro Screws: The Tiny Titans of Global Trade
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Micro Screws"?
Micro Screws, often categorized under "Screws and Bolts," are small threaded fasteners typically defined by their diameter (often <6mm) and precise engineering applications. In international trade, they are not a single unified category but are split based on material composition and specific usage.
1. Iron or Steel Micro Screws:
The most common type, used in general electronics, machinery, and assembly.
Classification Logic: Based on shape (screw/bolt) and inferred material (iron/steel), falling under Chapter 73.
2. Copper or Copper-Alloy Micro Screws:
Used in high-conductivity applications, jewelry, or specific anti-corrosion needs.
Classification Logic: Shape matches threaded articles, but material shifts classification to Chapter 74.
3. Miscellaneous Metal Mounting/Support Hardware:
Sometimes, small screws are classified as accessories to larger metal fixtures (like brackets) rather than general fasteners, depending on the specific tariff structure's "residual" clauses.
Classification Logic: Inferred as base metal accessories under Chapter 83.
⚠️ Critical Distinction Point:
- If the screw is Iron/Steel → It falls under 7318.14 or 7318.15.
- If the screw is Copper → It falls under 7415.33.
- If the item is considered a Bracket/Accessory rather than a standalone fastener → It may fall under 8302.49.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, here are the potential HS Codes and their logical justifications:
| HS Code | Product Description & Classification Logic | Inferred Material | Key Tax Rate (US/China) |
|---|---|---|---|
7318.14.10.60 |
Iron/Steel Screws/Bolts: Threads formed by rolling. Matches shape (screw) and "micro" implies small diameter. Inferred as metal/iron-based. | Iron/Steel | 91.2% |
7318.15.60.70 |
Iron/Steel Other Screws: Matches shape. No material conflict with general "other" screws in Chapter 73. | Iron/Steel | 91.2% |
7415.33.05.00 |
Copper Threads/Products: Shape matches. Inferred as copper/copper-head material. Fits "copper articles" category. | Copper | 88.0% |
8302.49.80.90 |
Base Metal Mounting Hardware: Classified as "other mounts/fittings." Inferred as base metal. Treated as accessory/part rather than pure fastener. | Base Metal | 38.5% |
7415.33.80.50 |
Other Copper Threaded Articles: Matches shape. Inferred as copper. No material conflict. | Copper | 88.0% |
🔍 Key Insight:
- Steel/Iron Screws are heavily taxed due to trade restrictions (Section 301 + Section 232).
- Copper Screws also face high tariffs due to "Section 122" specific provisions for copper/aluminum.
- Chapter 83 (Accessories) offers a significantly lower total tax rate (38.5%) compared to Chapter 73 (91.2%), making the classification argument critical.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Add-ons & Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (and subsequent imports)
🎯 1. 7318.14.10.60 & 7318.15.60.70 —— Iron/Steel Micro Screws
| Item | Detail |
|---|---|

| Base Duty | 3.5% (Ad Valorem) |
| Section 301 Surcharge | +25.0% |
| Section 122 Surcharge | +10.0% |
| Additional Steel/Aluminum/Copper Tariff | Not Applied (or not explicitly listed in this specific residual code's heavy surcharge bundle in the source data) |
| Total Effective Tax Rate | 38.5% |
| Tax Calculation | CIF Value × 38.5% |
| De Minimis Eligibility | ❌ None (Based on source data logic) |
| Legal Basis Path | USITC:8302.49.80.90 → FOOTNOTE:301 → FOOTNOTE:122 |
📌 Critical Advantage:
- This code offers the lowest tax rate (38.5%) among all options.
- Strategy: If the micro screws are used as parts of a bracket, hinge, or fixture, they may be argued as "accessories/mounts" (Chapter 83) rather than general fasteners (Chapter 73). This can save 52.7% in taxes (91.2% - 38.5%).
🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)
✅ 1. Document Checklist (Must-Haves)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specifications | ✔️ | Must specify diameter, length, thread pitch, and material (e.g., "Stainless Steel 304", "Brass"). |
| ✅ Material Certificates | ✔️ | Mill test certificates or supplier declarations proving material (Steel vs. Copper). Crucial for avoiding misclassification penalties. |
| ✅ Product Photos (Clear) | ✔️ | Show thread detail and overall shape. Help customs distinguish between "screw" and "mounting accessory." |
| ✅ Commercial Invoice | ✔️ | Clearly state: "Micro Screws, Steel, M2x5mm" OR "Metal Mounting Brackets with Screws." |
| ✅ Packing List | ✔️ | Itemize quantities. Avoid vague terms like "Hardware." |
✅ 2. Declaration Tactics (Key Mantras)
🔥 “Shape Determines Chapter, Material Determines Rate, Accessory Logic Saves Money!”
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Pure Iron/Steel Screws | 7318.14.10.60 |
Do not try to hide material. Accept the 91.2% rate or argue for Chapter 83 if part of a kit. |
| Pure Copper Screws | 7415.33.05.00 |
Declare as Copper. Do not declare as Steel to avoid the "Copper" surcharge; customs will inspect and fine you. |
| Screws sold with Brackets/Fixtures | Argue for 8302.49.80.90 |
Declaring as pure screws incurs 91.2%. If sold as a "Bracket Kit," you may qualify for 38.5%. |
| Mixed Materials | Split Declaration | Separate steel screws and copper screws. Do not mix them under one HS code. |
✅ 3. Special Situations
| Situation | Handling Advice |
|---|---|
| OEM Custom Screws | Provide OEM drawings. If the shape is unique and not a standard fastener, argue for Chapter 83 (Accessories) to lower the tax. |
| Micro Screws for Electronics | Ensure no electronic components are included. If it’s just the screw, it’s hardware. If it’s a screw + PCB, it’s electronic assembly. |
| Small Volume (De Minimis) | ❌ Do Not Rely on De Minimis. Most hardware from China >$800 (or even lower thresholds under new rules) is subject to full inspection and tariffs. The source data indicates deny_de_minimis. |
🌍 V. Global Main Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 7318.14.10.60 or 8302.49.80.90 |
38.5% - 91.2% | None specific for hardware, but material proof needed | Highest risk zone. Section 301 + 232 apply. |
| 🇨🇳 China | 7318.14.10.60 |
~6-10% | None | Domestic trade, lower impact. |
| 🇪🇺 EU | 7318.15.00.00 |
2.7% + Anti-dumping? | CE (if part of machinery) | EU has different anti-dumping rules for steel fasteners. Check EU tariffs separately. |
| 🇬🇧 UK | 7318.15.00.00 |
2.7% | UKCA | Post-Brexit rules similar to EU but independent. |
📌 Conclusion:
- The USA is the only major market with these extreme punitive tariffs (up to 91.2%).
- Strategy for US Market: If the micro screws are small components of a larger assembly (like a bracket or hinge), strictly argue for Chapter 83 (8302.49.80.90) to achieve the 38.5% rate. Pure standalone screws will likely face the 91.2% rate.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Declaring "Screws" as "Nuts" or "Washers"
👉 Consequence: Customs may reclassify based on physical inspection, leading to back-taxes and penalties.
❌ Error 2: Misdeclaring Copper as Steel to Avoid Copper-Specific Surcharges
👉 Consequence: If customs tests and finds copper, they will apply the 88% rate anyway + fines. Honesty with material proof is better.
❌ Error 3: Ignoring the "Accessory" Argument
👉 Consequence: Paying 91.2% when 38.5% was available by declaring as "Mounting Hardware."
❌ Error 4: Assuming De Minimis Applies
👉 Consequence: Package seized. Hardware from China is heavily scrutinized.
✅ Correct Practice:
"Steel Micro Screws, M2x4mm, Flat Head, Black Oxide Finish, HS 7318.14.10.60"
OR
"Copper Mounting Brackets with Integrated Screws, HS 8302.49.80.90" (If structurally a bracket).
🎯 VII. Conclusion: Precision Classification Saves Fortune
🎯 Remember Mantra:
🔹 "Steel Screws = 91.2% (Ouch!)”
🔹 “Copper Screws = 88.0% (Expensive!)”
🔹 “Bracket/Accessory Logic = 38.5% (The Goal!)”
🔹 “Material Proof is Your Shield!”
📌 Pro Tip:
If you are exporting micro screws to the US, consult a customs broker to evaluate if your product can be legally classified as a "part of a mounting system" (Chapter 83) rather than a generic fastener (Chapter 73). The 52.7% tax difference is huge.

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
