🔩 Mini Screw (微型螺丝)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is a "Mini Screw"?
A "mini screw" is not a standalone HS Code category but a descriptive term for fasteners based on size and material. In international trade, classification depends strictly on: 1. Material: Iron/Steel, Copper, or Other Base Metals. 2. Head Type: Hexagon head, Flat head, Round head, etc. 3. Size: "Mini" usually implies a diameter < 6mm.
⚠️ Critical Distinction:
- If made of Iron/Steel → Falls under Chapter 73.
- If made of Copper → Falls under Chapter 74.
- If classified as a Accessory/Bracket rather than a standalone fastener → Falls under Chapter 83 (less common, higher risk of reclassification).
📦 II. HS Code Classification Matrix (2026 Latest Tariff Data)
Based on the provided data, here are the 5 potential HS Codes for "Mini Screws," ranked by likelihood and tax impact:
| HS Code | Product Description & Logic | Total Tax Rate (China to US) | Key Classification Logic |
|---|---|---|---|
8302.49.80.90 |
Other Mounting Fittings / Parts (Inferred as Base Metal) | 38.5% | ✅ Lowest Tax Option Inferred as "Base Metal" accessories/parts. Classified under "Other brackets, fittings, and similar articles." |
7415.33.05.00 |
Copper Screws/Washers (Specific Subheading) | 88.0% | High Tax Form matches "threaded products." Inferred as Copper. Includes specific copper accessories. |
7415.33.80.50 |
Other Copper Screws/Nuts | 88.0% | High Tax Matches "Screw" form. Inferred as Copper. Fits "Other" category under Copper chapter. |
7318.14.10.60 |
Iron/Steel Hexagon Head Screws (Micro/Diameter <6mm) | 91.2% | Highest Tax Matches "Screw" category. Inferred as Metal (Steel/Iron). "Mini" implies small diameter. |
7318.15.60.70 |
Other Iron/Steel Screws & Bolts | 91.2% | Highest Tax Matches "Screw" category. Inferred as Metal. Broad category for non-hex steel screws. |
🔍 Key Insight:
- Iron/Steel screws (Ch 73) carry the highest tariff burden (91.2%) due to Section 301/122 tariffs.
- Copper screws (Ch 74) are slightly lower (88.0%) but still heavily taxed.
- Chapter 83 offers a significant tax advantage (38.5%), but only if the customs broker can justify classifying them as "mounting fittings/parts" rather than simple "fasteners." This requires strong documentation (e.g., used in specific assembly, not general purpose).
💰 III. 2026 Tariff Rate Breakdown (Detailed Tax Policy)

- Warning: Customs may challenge this if the screws are generic hardware. You must prove they are "parts" or "fittings" for specific machinery, not standalone fasteners.
🎯 2. 7415.33.05.00 & 7415.33.80.50 — Copper Screws
| Item | Details |
|---|---|
| Base Rate | 3.0% (ad valorem) |
| Section 301 Surcharge | +25% |
| Section 122 Surcharge | +10% (Steel/Aluminum/Copper Products) |
| Total Tax Rate | 88.0% |
| Tax Calculation | CIF Value × 88.0% |
| De Minimis Exemption? | ❌ NO (Denied) |
| Legal Basis | USITC:7415.33.05.00 → Section 301 → Section 122 (Copper) |
📌 Explanation:
- Copper products face specific 122 tariffs.
- High tax makes copper mini-screws very expensive to import into the US. Consider sourcing from non-China origins if volume is high.

| Item | Details |
|---|---|
| Base Rate | 6.2% (ad valorem) |
| Section 301 Surcharge | +25% |
| Section 122 Surcharge | +50% (Steel/Aluminum/Copper Products) |
| Total Tax Rate | 91.2% |
| Tax Calculation | CIF Value × 91.2% |
| De Minimis Exemption? | ❌ NO (Denied) |
| Legal Basis | USITC:7318.14.10.60 → Section 301 → Section 122 (Steel) |
📌 Explanation:
- Steel screws face the highest possible tariff.
- The 50% Section 122 tariff for steel products is the key driver.
- Result: Over 90% tax burden. This is prohibitively expensive for most commercial shipments unless the margin is very high.
🛠️ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
✅ 1. Documentation Checklist (Mandatory)
| Document | Required? | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must include: Material (Steel/Copper), Diameter, Length, Thread Type, Head Type. |
| ✅ Material Certificate | ✔️ | Crucial for proving if it's Steel (Ch 73) or Copper (Ch 74). |
| ✅ Commercial Invoice | ✔️ | Clearly state "Mini Screw" + HS Code. Avoid vague terms like "Hardware Parts." |
| ✅ Photos (Including Close-up) | ✔️ | Show threads, head shape, and material finish. |
| ✅ Packing List | ✔️ | Detail net weight vs. gross weight. |
✅ 2. Classification Strategy (Key Recommendations)
| Strategy | Recommendation | Risk |
|---|---|---|
Attempt Chapter 83 (8302.49.80.90) |
✅ Recommended Argue that screws are "accessories" or "parts" for specific machinery, not general hardware. |
Medium Customs may reject if they look like standard fasteners. Requires strong technical justification. |
| Standard Ch 73/74 | ⚠️ Accept High Tax If Chapter 83 is rejected, declare accurately under Ch 73 (Steel) or Ch 74 (Copper). |
High Tax Be prepared for 88-91% duty. |
| De Minimis | ❌ Do Not Rely On Do not use 800.33 or 128.32 for these items. They are explicitly denied. |
Seizure/Fine Attempting de minimis for steel/copper screws will lead to penalties. |
✅ 3. Special Case Handling
| Situation | Advice |
|---|---|
| Mixed Materials | If screws are steel with copper heads, classify based on the essential character (usually the main body material). |
| OEM Custom Screws | Provide design drawings. Custom parts may have better arguments for Chapter 83 classification. |
| Small Quantity Samples | Still subject to tariffs. Do not assume samples are exempt. |
| Non-China Origin | If sourced from Vietnam, Mexico, or Thailand, apply for Free Trade Agreement (FTA) benefits. Dramatically reduces tax. |
🌍 V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Approx. Tax (China Origin) | Remarks |
|---|---|---|---|
| 🇺🇸 USA | 8302.49.80.90 (Best) |
38.5% (if successful) 91.2% (if Steel) |
Highest tariffs globally. Critical to optimize classification. |
| 🇨🇳 China | 7318.15.60.70 |
5-6% | Standard import duty. No Section 122/301. |
| 🇪🇺 EU | 7318.15.60.70 |
0-2.5% (if GSP) | Generally lower than US. Check for duty drawbacks. |
| 🇦🇺 Australia | 7318.15.60.70 |
5% | No high surcharges like US. |
| 🇯🇵 Japan | 7318.15.60.70 |
0-1.5% | Low tariffs. JETRO partnership benefits may apply. |
📌 Conclusion:
- The US market is the most challenging for mini screws due to Section 301 and 122 tariffs.
- Cost Optimization is Essential. If possible, source from non-China countries to avoid the 25-50% surcharges.
📌 VI. Common Errors & Pitfalls (Blood Lessons)
❌ Error 1: Declaring steel screws as "Plastic Hardware" to avoid tariffs.
👉 Consequence: Customs inspection, seizure, and fraud penalties.
❌ Error 2: Using "Mini Screw" as the only description.
👉 Consequence: Customs assigns a default higher rate or rejects the entry for insufficient info.
❌ Error 3: Assuming small packages qualify for De Minimis.
👉 Consequence: Strictly Denied for steel/copper screws from China. Package size does not matter.
❌ Error 4: Misclassifying steel screws as Chapter 83 without justification.
👉 Consequence: Audit risk, back taxes, and interest. Must provide strong "part vs. fastener" argument.
✅ Correct Action:
"Mini Hexagon Head Screw, Steel, Diameter 4mm, Length 10mm, Zinc Plated, Model XYZ, Origin China"
🎯 VII. Conclusion: Professional Classification Saves Money
🎯 Remember:
🔹 "Steel Screws = 91.2% Tax"
🔹 "Copper Screws = 88.0% Tax"
🔹 "Chapter 83 Parts = 38.5% Tax (If Justified)"
📌 Strategic Tip:
If your mini screws are not used as general hardware but as specific components for a larger machine, aggressively pursue Chapter 83 (8302.49.80.90) classification. Provide technical drawings showing integration into a larger system.
📣 Immediate Action:
📞 Consult a US Customs Broker for a Pre-Ruling Request on Chapter 83 classification.
🌍 Consider Supply Chain Diversification (Vietnam/Mexico) to mitigate US tariff risks.

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
