๐ฉ Double Line Hose Clamp Accessory Set (็ฎก้ไปถ/ๆฅๅคด)
๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Strategy
๐ 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).
โ ๏ธ Key Distinction Point:
- If the set includes metal elbows, straight connectors, or threaded fittings โ Infer as Iron/Steel โ HS Code 7307 or 7318.
- If the set includes plastic quick-connects, PVC adapters, or plastic hose couplings โ Infer as Plastic โ HS Code 3917.
๐ฆ 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. |
๐ 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.

๐ ๏ธ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)
โ 1. Document Checklist (Non-negotiable)
| Document | Required | Explanation |
|---|---|---|
| โ Product Specifications | โ๏ธ | Must explicitly state Material (e.g., "Stainless Steel 304" or "PVC Plastic"). Ambiguity leads to re-classification. |
| โ Photos (Clear) | โ๏ธ | Show the connection type (threaded, slip-fit, clamped). |
| โ Commercial Invoice | โ๏ธ | Item description must match HS Code logic. E.g., if Steel, say "Steel Pipe Fitting"; if Plastic, say "Plastic Hose Connector". |
| โ Bill of Lading | โ๏ธ | Ensure weight and quantity match. |
| โ Material Test Report | โ๏ธ | For steel, confirm it's not classified as a tool. For plastic, confirm it's not classified as a tube. |
โ 2. Declaration Strategy (Key Mnemonic)
๐ฅ "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. |
โ 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. |
๐ V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code (Steel) | Tariff (Approx.) | HS Code (Plastic) | Tariff (Approx.) | Notes |
|---|---|---|---|---|---|
| ๐บ๐ธ 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. |
| ๐จ๐ณ China | 7307.99.50 |
~4.3% | 3917.39.00 |
~3.1% | Low basic rates, no Sec 301/232. |
| ๐ช๐บ EU | 7307.99 |
~6.5% | 3917.39 |
~5.3% | No US-style surcharges. |
| ๐ฌ๐ง UK | 7307.99 |
~6.5% | 3917.39 |
~5.3% | Post-Brexit tariffs similar to EU. |
๐ 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.
๐ VI. Common Errors & Pitfall Guide (Blood & Tears Lessons)
โ Error 1: Declaring Steel Fittings as "General Accessories" without specifying material.
๐ Consequence: CBP will assign the highest duty rate and issue a penalty.
โ
Fix: Always specify "Iron/Steel" or "Plastic" in the description.
โ Error 2: Confusing 7307 (Pipe Fittings) with 7318 (Fasteners).
๐ 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.
โ
Fix: Use the product's primary function. If it connects pipes, it's 7307. If it clamps, it might be 7318.
โ Error 3: Ignoring Section 232 for Steel.
๐ Consequence: Underestimating cost by ~50%.
โ
Fix: Always add 50% for steel products from China to the US.
๐ฏ VII. Conclusion: Professional Declaration, Save Costs!
๐ฏ Key Takeaway:
๐น "Steel Fittings: 89%+ Tax. Plastic Fittings: 38% Tax. Choose Material Wisely!"
๐น "Double Line Hose Clamp Set" is not a standard HS Code. You MUST classify based on Material and Function.
๐ 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.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
