🌊 PU Hose (Polyurethane Hose)
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: What Exactly is a "PU Hose"?
Polyurethane (PU) hoses are flexible or rigid tubes made from polyurethane elastomers. They are widely used in pneumatics, hydraulics, food processing, and industrial automation due to their high abrasion resistance, flexibility, and chemical stability.
In international trade, the classification depends heavily on r Rigidity and Length. The provided data focuses specifically on Rigid PU hoses/pipes of other plastics (excluding PVC, PE, etc., which have separate subheadings) with a length of less than 200 mm.
⚠️ Key Distinction:
- Rigid Tubes/Pipes: These hold their shape when unattached and are used for structural flow (e.g., pneumatic line connectors, rigid intake tubes). → HS Code: 3917.29.00.90/50
- Flexible Hoses: If the product is flexible, coiled, or used as a flexible connector, it typically falls under 3917.23 or 3917.29 depending on diameter. However, the data provided specifically targets Rigid products <200mm.
- Fittings: If the item is an elbow, joint, or flange (not a tube itself), it may fall under 3917.29.00.90 "Fittings".
📦 II. HS Code Classification Details (Based on Provided Data)
| HS Code | Product Description | Applicable Scenario | Rigidity | Max Length |
|---|---|---|---|---|
3917.29.00.90 |
Tubes, pipes and hoses, rigid: Of other plastics: Other (Fittings/Other Rigid Parts) | Rigid PU tubes/pipes <200mm, or rigid plastic fittings (joints, elbows) not elsewhere specified. | ✅ Rigid | < 200 mm |
3917.29.00.50 |
Tubes, pipes and hoses, rigid: Of other plastics: Less than 200 mm in length | Specific sub-category for rigid PU tubes/pipes under 200mm. | ✅ Rigid | < 200 mm |
🔍 Critical Note on "Other Plastics":
- This code applies to PU (Polyurethane) because PU is often classified under "Other Plastics" in tariff schedules unless specifically listed (like PVC or Polyethylene).
- If your PU hose is flexible (not rigid) or longer than 200mm, this specific data block (3917.29.00) may NOT apply. You would need to check3917.23(Flexible) or3917.21/3917.22(Longer rigid tubes).
- Data Constraint: The provided dataset only covers Rigid items < 200mm. Do not apply this to long industrial hoses.
💰 III. 2026 Tariff Rate Detailed Explanation (Based on Provided Data)
✅ Applicable Data Source: Provided JSON Data
✅ HS Codes:3917.29.00.90/3917.29.00.50
✅ Product Type: Rigid PU Tubes/Pipes (<200mm) or Fittings
🎯 1. 3917.29.00.50 & 3917.29.00.90 – Rigid Plastic Tubes/Pipes/Fittings
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Additional Tariff (Surtax) | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Calculation | No duty payable on CIF value for these specific codes under this dataset. |
| Legal Basis | Based on the provided tax detail: 基础关税: 0.0%, 加征关税: 0.0% |
📌 Interpretation:
- According to the provided data, the total tax burden for these specific rigid PU tubes/fittings is ZERO.
- Warning: This 0% rate may apply only to specific trade agreements (e.g., GSP, specific bilateral FTAs) or specific origin countries (e.g., US imports from certain partners, or domestic trade).
- Do not assume 0% globally: If importing into the US from China, standard MFN rates for 3917.29 may be higher (e.g., 3.4% or more). The provided data explicitly states 0.0%, so we adhere to that for this analysis. Verify if this 0% applies to your specific Country of Origin.
🛠️ IV. Customs Clearance Practical Advice (Best Practices)
✅ 1. Required Documentation Checklist
| Document | Must Provide? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must explicitly state: Material (PU/Polyurethane), Rigid vs. Flexible, Outer Diameter (OD), Inner Diameter (ID), and Length. |
| ✅ Technical Drawing | ✔️ | Crucial to prove the item is "Rigid" and "< 200 mm". Flexible hoses must be marked as such to avoid misclassification. |
| ✅ Commercial Invoice | ✔️ | Description must match HS code: e.g., "Rigid Polyurethane Tube, 10mm ID, 150mm Length, for Pneumatic Systems". Avoid vague terms like "Plastic Hose". |
| ✅ Certificate of Origin (CO) | ✔️ | If claiming 0% tariff, origin must be verified. |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | PU is generally safe, but some plasticizers may require declaration for food/medical grade. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Rigid Under 20, PU Not PVC, Fit for Pneumatics, Clear and Specific!"
| Scenario | Correct Declaration | Common Mistake |
|---|---|---|
| Short Rigid PU Tube | 3917.29.00.50 |
Misclassifying as flexible hose (3917.23) → Higher tax |
| PU Elbow/Joint | 3917.29.00.90 (Fittings) |
Calling it a "tube" → Risk of inspection |
| Long Flexible PU Hose | NOT Covered in this data | Trying to force 3917.29.00 → Rejection/Seizure |
| PVC Tube | NOT Covered | PU and PVC are different HS subheadings. PVC has its own code (e.g., 3917.21). |
✅ 3. Special Handling Scenarios
| Situation | Advice |
|---|---|
| Mixed Shipment | If sending rigid tubes AND flexible hoses, separate line items. Do not bundle under one HS code. |
| Food/Pharma Grade | If PU is food-grade, add "Food Contact Compliant" to invoice. May require additional FDA/LFGB documentation, though HS code remains same. |
| Origin Verification | Since data shows 0% tax, confirm if this is an MFN rate or a Preferential Rate. If importing from China to US, standard duty might not be 0%. Verify with local customs broker. |
🌍 V. Global Market Comparison (Based on Provided Data)
| Country/Region | HS Code (Rigid PU <200mm) | Tax Rate (Per Data) | Remarks |
|---|---|---|---|
| 🇺🇸 USA | 3917.29.00.90 / .50 |
0.0% | Per provided data. Verify if Section 301 tariffs apply (usually they don't for plastics, but check). |
| 🇨🇳 China | 3917.29.00 |
Varies (Import Duty) | Import duty typically ~3-6%, but export from US may be 0% per data. |
| 🇪🇺 EU | 3917.29.90 |
~4.5% | EU often applies standard ad valorem duty. Data does not cover EU rates. |
| 🇯🇵 Japan | 3917.29.00 |
~0-5% | Check JETRO database for current zero-rated lists. |
📌 Conclusion:
- The provided data indicates 0% tax for these specific rigid PU parts.
- This is likely a preferential rate or a specific national policy.
- Do not assume 0% for all countries. Always validate origin-specific tariffs.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Classifying Flexible PU Hoses under 3917.29.00
👉 Consequence: Misclassification. Flexible hoses fall under 3917.23 or 3917.21 depending on dimensions. Tax rate may differ.
❌ Error 2: Ignoring Length
👉 Consequence: If tube is 250mm, it does not fit <200mm category. Must use other subheadings (e.g., 3917.22 or 3917.29 general).
❌ Error 3: Calling it "Hose" when it is "Rigid Tube"
👉 Consequence: Customs may inspect to determine rigidity. If rigid, it goes to 3917.29. If flexible, it goes elsewhere. Be precise. Use "Rigid Polyurethane Tube" if rigid.
✅ Correct Declaration Example:
"Rigid Polyurethane (PU) Tube, ID 10mm, OD 14mm, Length 150mm, Non-Flexible, for Pneumatic Applications, Model XYZ"
🎯 VII. Conclusion: Precision in Plastic Goods Classification
🎯 Key Takeaway:
🔹 "Rigid Under 20cm, PU or Other Plastic, 0% Tax Possible!"
🔹 "Flexible or Longer? Look Elsewhere!"
🔹 "Check Origin for Zero Rate Validity!"
📌 Pro Tip:
Since the data shows 0% tax, this is a highly advantageous classification. Ensure your product is strictly rigid and under 200mm to qualify. If any doubt, consult a customs broker for an Advance Ruling.

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
