⚙️ Stainless Steel Nuts (The Unsung Heroes of Industrial Fasteners)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Stainless Steel Nuts"?
Stainless steel nuts are threaded fasteners designed to mate with bolts or screws to clamp materials together. In international trade, their classification depends heavily on material precision and specific shape definitions.
Key Distinction: * True Stainless Steel Fasteners: Specifically designed for fastening, falling under Chapter 7318. * General Steel Articles: If the item doesn't meet the strict definition of a "nut" or is considered a "part" of a larger steel structure, it may fall under Chapter 7326.
⚠️ Critical Classification Point:
- If it is a dedicated nut (hexagonal, flanged, etc.) made of stainless steel → HS 7318.16.00.60
- If it is misclassified as a bolt or generic steel article → HS 7318.15.20.61 / 7326.90.86.88 (Higher Risk/Tax)
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Scenario | Tax Rate | Risk Level |
|---|---|---|---|---|
7318.16.00.60 |
Stainless Steel Nuts (Dedicated Fastener) | Standard hex nuts, flanged nuts, locking nuts made of stainless steel | 67.5% | 🟢 Low (Correct Classification) |
7318.15.20.61 |
Stainless Steel Bolts (Misclassification Risk) | If labeled as bolt but is a nut, or vice versa; high scrutiny | 85.0% | 🔴 High (Wrong Category) |
7326.90.86.88 |
Other Articles of Iron/Steel (Generic) | If material is ambiguous or deemed "other steel product" | 87.9% | 🔴 Very High (Wrong Chapter) |
7326.19.00.80 |
Forged/Stamped Steel Articles | If manufacturing process is emphasized over function | 87.9% | 🔴 Very High (Wrong Chapter) |
7318.15.20.91 |
Other Stainless Steel Fasteners (Bolts) | Alternative bolt classification, often used for similar hardware | 85.0% | 🔴 High (Wrong Category) |
🔍 Key Reminder:
- Nut vs. Bolt: A nut (7318.16) has internal threads; a bolt (7318.15) has external threads. Do not mix them up! - Stainless Steel: Must be clearly specified. If just "Steel," it may fall under 7326, increasing the base tax. - Chapter 7318 is the correct chapter for nuts and bolts. Chapter 7326 is for "Other articles of iron or steel" and should only be used if the item is NOT a standard fastener.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
✅ 1. Required Documentation Checklist (Non-negotiable)
| Document | Mandatory | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state: "Stainless Steel," "Nut," Material Grade (e.g., 304, 316). |
| ✅ Technical Drawing | ✔️ | Show internal threads to prove it is a nut, not a bolt. |
| ✅ Product Photos (Clear) | ✔️ | Show hex shape, thread type, and material label. |
| ✅ Commercial Invoice | ✔️ | Description: "Stainless Steel Hex Nuts, Grade 304, HS 7318.16.00.60." |
| ✅ Packing List | ✔️ | Weight, dimensions, and quantity. |
| ✅ Material Test Report | ✔️ | To prove Stainless Steel content (avoiding "Carbon Steel" misclassification). |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Nut is Nut, Bolt is Bolt. Stainless Must Be Proved. Don't Be Lazy, Classify Correctly!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Standard Hex Nut | 7318.16.00.60 |
Mislabeling as "Bolt" → 85% Tax |
| Flanged Nut | 7318.16.00.60 |
Mislabeling as "Steel Part" → 87.9% Tax |
| Nylon Insert Lock Nut | 7318.16.00.60 (Check if nylon is main) |
General "Hardware" → Risk of 87.9% |
| Stainless Steel Bolts | 7318.15.20.61 |
Mislabeling as "Nuts" → 85% Tax |
✅ 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| Mixed Containers (Nuts + Bolts) | Declare separately! Nuts under 7318.16, Bolts under 7318.15. Do not lump them as "Fasteners." |
| Coated Nuts | If coating is minor (e.g., zinc plating on steel), it may change classification. For Stainless, coating is usually minimal. |
| Custom/Non-Standard Nuts | If shape is unusual, provide detailed drawings. Customs may still classify under 7318 if it functions as a nut. |
| Origin Marking | Ensure products are marked "Made in China" to avoid anti-circumvention claims. |

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
