🔩 Double Line Hose Clamp Accessory Set (管附件/接头)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Strategy
📌 I. Product Definition & Classification: Do You Really Know "Hose Clamps" and "Fittings"?
The "Double Line Hose Clamp Accessory Set" typically consists of hose clamps, connectors, adapters, or fittings used for fluid transmission (hydraulic, pneumatic, or cooling systems). In international trade, its classification depends heavily on Material and Function.
There are two main branches: 1. Metal Fittings/Connectors (Steel/Iron): Used for high-pressure or rigid connections. Classified under Chapter 73 (Articles of Iron or Steel). 2. Plastic Fittings/Connectors: Used for low-pressure, corrosive, or electrical insulation applications. Classified under Chapter 39 (Plastics and Articles Thereof).
⚠️ Key Distinction Point:
- If the set includes metal elbows, straight connectors, or threaded fittings → Infer as Iron/Steel → HS Code 7307 or 7318.
- If the set includes plastic quick-connects, PVC adapters, or plastic hose couplings → Infer as Plastic → HS Code 3917.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the input data, here are the four most likely HS Codes for this product category:
| HS Code | Product Description | Application Scenario | Inference Logic from Data |
|---|---|---|---|
| 7307.99.50.45 | Pipe Fittings, Other (Iron/Steel) | General iron/steel pipe connectors, flanges, or heavy-duty clamps. | Inferred as Iron/Steel pipe accessories based on name "Fitting". |
| 7307.92.90.00 | Pipe Fittings, Of Iron or Steel - Threaded Elbows, Bends, and Socket Joints | Specific threaded connectors, bends, or socket joints made of steel. | Inferred as Steel metal pipe accessories, belonging to "Other threaded elbows/bends". |
| 7318.19.00.00 | Articles of Iron or Steel (Other) - Screws, Bolts, Nuts, Washers, etc. | Fasteners, clamps, or connecting accessories made of metal. | Inferred as Metal fastening/connecting accessories, falling under "Other" threaded items. |
| 3917.39.00.50 | Pipes, Tubing, Hose Fittings, and Connectors, of Plastics - Other | Plastic hose connectors, adapters, or non-rigid plastic fittings. | Inferred as Plastic/Metal accessories, specifically hose fittings under "Other". |
| 3917.40.00.95 | Joints, Elbows, and Couplings, of Plastics | Plastic joints, elbows, and couplings specifically for hose systems. | Inferred as Plastic accessories for hoses, under "Plastic Accessories" category. |
🔍 Important Reminder:
- Metal vs. Plastic: This is the biggest pitfall. A "Hose Clamp Set" containing metal clamps + metal connectors usually falls under Chapter 73. If it contains plastic clamps + plastic connectors, it falls under Chapter 39. Mixed sets may be classified by the primary component or the component that determines the essential character. - "Accessory Set" Warning: If the set is packaged as a single unit (e.g., a kit), customs may classify the entire kit based on the dominant item. Do not split the declaration artificially unless instructed.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)
✅ 1. Document Checklist (Non-negotiable)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specifications | ✔️ | Must explicitly state Material (e.g., "Stainless Steel 304" or "PVC Plastic"). Ambiguity leads to re-classification. |
| ✅ Photos (Clear) | ✔️ | Show the connection type (threaded, slip-fit, clamped). |
| ✅ Commercial Invoice | ✔️ | Item description must match HS Code logic. E.g., if Steel, say "Steel Pipe Fitting"; if Plastic, say "Plastic Hose Connector". |
| ✅ Bill of Lading | ✔️ | Ensure weight and quantity match. |
| ✅ Material Test Report | ✔️ | For steel, confirm it's not classified as a tool. For plastic, confirm it's not classified as a tube. |
✅ 2. Declaration Strategy (Key Mnemonic)
🔥 "Material Determines Code, Steel is Heavy, Plastic is Light!"
| Scenario | Correct Declaration | Wrong Practice | Consequence |
|---|---|---|---|
| Steel Fittings | Use 7307/7318 codes. Declare as "Steel Pipe Fitting". | Declare as "Accessory" or "Plastic" to avoid tax. | Customs Penalty + Retrospective Tax + Seizure. |
| Plastic Fittings | Use 3917 codes. Declare as "Plastic Hose Connector". | Declare as "Steel" to match old habits. | Higher tax (38% vs 40%, but mostly wrong classification risk). |
| Mixed Set (Steel + Plastic) | Declare by Essential Character (usually the dominant item or the item determining the set's function). | Split into two HS Codes without justification. | Delay in clearance, request for additional info. |
| Hose Clamps (Metal) | May fall under 7318.19.00.00 (Other Steel Articles) if not strictly a pipe fitting. | Force into 7307. | Potential challenge by CBP. |
✅ 3. Special Case Handling
| Case | Handling Advice |
|---|---|
| OEM Custom Clamps | Provide design drawings. If custom steel, ensure it's not classified as a "Machine Tool Part" (different tax). |
| Set of Clamps + Hoses | If hoses are also included, the set may be classified under the Hose (if dominant) or Fitting. Check Chapter 40 (Rubber/Hoses) vs Chapter 39/73. |
| Origin Verification | Ensure the certificate of origin states China if claiming the current tariffs. If re-exported, ensure no substantial transformation occurred. |
🌍 V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code (Steel) | Tariff (Approx.) | HS Code (Plastic) | Tariff (Approx.) | Notes |
|---|---|---|---|---|---|
| 🇺🇸 USA | 7307.99.50.45 |
89.3% (High!) | 3917.39.00.50 |
38.1% | Steel is penalized heavily. Plastic is cheaper but still has Sec 301. |
| 🇨🇳 China | 7307.99.50 |
~4.3% | 3917.39.00 |
~3.1% | Low basic rates, no Sec 301/232. |
| 🇪🇺 EU | 7307.99 |
~6.5% | 3917.39 |
~5.3% | No US-style surcharges. |
| 🇬🇧 UK | 7307.99 |
~6.5% | 3917.39 |
~5.3% | Post-Brexit tariffs similar to EU. |
📌 Conclusion:
- US Market: Plastic fittings are significantly more cost-effective than steel fittings due to Section 232.
- Steel Market: High tariffs make steel fittings expensive for end-users. Consider supply chain diversification (e.g., Vietnam, Mexico) if possible, though Section 232 may still apply depending on origin rules.
📌 VI. Common Errors & Pitfall Guide (Blood & Tears Lessons)
❌ Error 1: Declaring Steel Fittings as "General Accessories" without specifying material.
👉 Consequence: CBP will assign the highest duty rate and issue a penalty.
✅ Fix: Always specify "Iron/Steel" or "Plastic" in the description.
❌ Error 2: Confusing 7307 (Pipe Fittings) with 7318 (Fasteners).
👉 Consequence: If it's a hose clamp that holds a hose to a pipe, it might be a fastener (7318), not a fitting (7307). Misclassification can lead to audits.
✅ Fix: Use the product's primary function. If it connects pipes, it's 7307. If it clamps, it might be 7318.
❌ Error 3: Ignoring Section 232 for Steel.
👉 Consequence: Underestimating cost by ~50%.
✅ Fix: Always add 50% for steel products from China to the US.
🎯 VII. Conclusion: Professional Declaration, Save Costs!
🎯 Key Takeaway:
🔹 "Steel Fittings: 89%+ Tax. Plastic Fittings: 38% Tax. Choose Material Wisely!"
🔹 "Double Line Hose Clamp Set" is not a standard HS Code. You MUST classify based on Material and Function.
📌 Tips:
- If your product is 100% Steel, budget for ~89-91% tax.
- If your product is 100% Plastic, budget for ~38-40% tax.
- Pre-Ruling: Apply for an Advance Ruling from US CBP to confirm the HS Code before shipping. This is the best way to avoid surprises.

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
