πΏ PU Hose: Polyurethane Fluid Transfer Pipes
π HS Code Reference & Customs Clearance Guide | 2026 Tariff Breakdown | Strategic Import Strategies
π Part 1: Product Definition & Classification: Do You Really Know "PU Hose"?
PU Hose (Polyurethane Hose) is a critical component in industrial fluid transfer, pneumatic systems, and chemical processing. It is valued for its high abrasion resistance, flexibility, and clarity. In international trade, classification depends strictly on rigidity, material composition, and dimensions.
β οΈ Key Distinction Point:
- If the hose is flexible (can be bent by hand), it typically falls under Chapter 39.01β39.14 but specific subheadings for flexible tubes are different.
- If the hose is rigid (cannot be bent without tools or breaks), it falls under HS Code 3917.2x.
- Critical Dimension: Length < 200mm often triggers specific "short rigid tube" classifications in some jurisdictions, but broadly, Rigidity is the primary driver for Chapter 3917.29.
PU (Polyurethane) is classified as "Other Plastics" because it is not Polyethylene (PE), Polypropylene (PP), PVC, or Polystyrene. Therefore, it falls under the "Other Plastics" bucket in HS Code 3917.29.
π¦ Part 2: HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided data, the product is classified as Rigid PU Hoses/Pipes.
| HS Code | Product Description | Key Characteristics | Material Type |
|---|---|---|---|
| 3917.29.00.90 | Tubes, pipes, and hoses, rigid: Of other plastics, Less than 200 mm in length | Short, rigid PU tubes (e.g., couplers, short connectors, small diameter rigid lines) | Polyurethane (Other) |
| 3917.29.00.50 | Tubes, pipes, and hoses, rigid: Of other plastics, Other | Long or standard rigid PU pipes not meeting the <200mm length criteria | Polyurethane (Other) |
π Important Note:
- Both codes fall under 3917.29.00 ("Tubes, pipes and hoses, rigid: Of other plastics").
- PU (Polyurethane) is explicitly "Other Plastics" (not PE, PP, PVC, PS, PMMA).
- The distinction between .90 and .50 is primarily based on length (<200mm vs. Other).
- If your PU hose is flexible, this data does not apply (flexible PU hoses usually fall under 3917.40.00.00 or similar, depending on diameter). This guide assumes RIGID PU Hose/Pipe as per the input data.

β Applicable Countries: United States (US)
β Origin: China (CN)
β Effective Time: Current (2026)
π― HS Code: 3917.29.00.90 / 3917.29.00.50
Product: Rigid Polyurethane (PU) Tubes/Pipes/Hoses (Other Plastics)
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (Ad Valorem) |
| Section 301 Additional Tariff | 0.0% (Note: Some plastic goods are excluded or have different rates; based on provided data, it is 0%) |
| IEEPA / Other Surcharges | 0.0% (Based on provided data) |
| Total Tax Rate | 0.0% |
| Tax Calculation | CIF Value Γ 0.0% = $0 Duty |
| De Minimis Eligibility | β Check with Carrier: Typically, low-value shipments may use Section 321 (De Minimis), but for commercial imports, this is the statutory rate. |
π Explanation:
- The base Most Favored Nation (MFN) rate for Rigid Pipes/Hoses of Other Plastics is 0%.
- Unlike electronics or steel, rigid plastic piping does not currently carry the heavy Section 301 tariffs (25%) or IEEPA surcharges in this specific HS classification according to the provided dataset.
- Zero Duty Advantage: This makes rigid PU piping highly competitive for US imports.
π οΈ Part 4: Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Required? | Notes |
|---|---|---|
| β Product Specifications | βοΈ | Must state: Material = Polyurethane (PU), State = Rigid, Length, Diameter, Pressure Rating. |
| β Commercial Invoice | βοΈ | Clearly describe as "Rigid Polyurethane Pipe/Hose", NOT just "Plastic Tube". |
| β Packing List | βοΈ | Include gross/net weight. PU is lightweight but dense; weight matters for freight class. |
| β Photo of Product | βοΈ | Show cross-section or label indicating "PU" or "Polyurethane". |
| β MSDS (Material Safety Data Sheet) | βοΈ | Required for chemical resistance claims and safety verification. |
β 2. Declaration Tips (Key Mnemonic)
π₯ "Rigid, Not Flexible, PU is Other, Length Matters!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Rigid PU Tube, <200mm | HS 3917.29.00.90 | Misdeclare as flexible hose β Wrong Chapter |
| Rigid PU Pipe, >200mm | HS 3917.29.00.50 | Misdeclare as PVC β Wrong Material |
| Flexible PU Hose | Not covered by this data (Likely 3917.40) | Forcing rigid code β Seizure |
| PU Hose with Metal Fittings | Separate Declaration | Combine β Complex classification errors |
π‘ Critical Advice:
- If the hose can be bent by hand, it is FLEXIBLE. Do NOT use 3917.29. Flexible hoses have different codes (e.g., 3917.40).
- If it requires tools to bend or breaks when bent, it is RIGID. Use 3917.29.
β 3. Special Cases
| Case | Handling Advice |
|---|---|
| PU Hose with Fittings | Declare separately. Fittings may have different HS codes (e.g., 3917.29.90 for fittings of other plastics). |
| Food Grade PU Hose | Ensure compliance with FDA 21 CFR 177.1640. No tariff change, but certification needed. |
| Flame Retardant PU | Specify material additives. May require UL certification for US market. |
| Reinforced PU Hose | If reinforced with fabric/mesh but still rigid, still likely 3917.29. If flexible, it becomes 3917.40. |
π Part 5: Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff Rate | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ United States | 3917.29.00.90 / .50 |
0% | FDA, UL (if electrical/flame) | Zero duty is key advantage. |
| π¨π³ China (Import) | 3917.29.90.00 |
~0-5% | CCC (if applicable) | Check local customs for "Other Plastics". |
| πͺπΊ European Union | 3917.29.00 |
0% | REACH, RoHS | Strict chemical reporting (REACH). |
| π¨π¦ Canada | 3917.29.90 |
0-5% | CFIA (if food/water contact) | CUSMA may apply for preferential rates. |
| π²π½ Mexico | 3917.29.00 |
0% | NOM Standards | USMCA benefits apply for US-origin goods. |
π Conclusion:
- US Market: Highly favorable with 0% duty.
- EU Market: Zero duty but strict REACH chemical compliance.
- Key Risk: Misclassifying Flexible PU hoses as Rigid to avoid other taxes (if any) is a major red flag. Always declare correct flexibility.
π Part 6: Common Mistakes & Pitfalls (Blood Lessons)
β Mistake 1: Declaring Flexible PU Hose as Rigid (3917.29) to simplify clearance.
π Consequence: Customs inspection reveals flexibility. Goods held, fines applied, reclassification to 3917.40.
β Mistake 2: Ignoring Material Composition.
π Consequence: If PU is mixed with PVC, it may not be "Other Plastics" but "PVC" (3917.21). Must declare exact polymer type.
β Mistake 3: Not declaring Fittings Separately.
π Consequence: If hose and fittings are shipped together, they may be classified as a "Kit" with a higher duty rate. Ship separately or declare clearly.
β Mistake 4: Assuming "Plastic Hose" = 0% Duty Everywhere.
π Consequence: Some countries impose anti-dumping duties on specific plastics. Check local lists.
β Correct Declaration Example:
"Rigid Polyurethane (PU) Pipe, ID 10mm, OD 14mm, Length 150mm, For Industrial Pneumatic Use, FDA Compliant"
π― Part 7: Conclusion: Professional Declaration, Zero Duty Advantage!
π― Remember This Mnemonic:
πΉ "Rigid PU, Code 29, Length Matters, Duty is Zero!"
πΉ "Flexible PU is Chapter 40, Rigid is 39, Don't Mix Them Up!"
π Pro Tip:
- If your PU hose is short (<200mm), use .90.
- If it is long, use .50.
- Both are 0% duty in the US.
- Always provide Material Safety Data Sheets (MSDS) to prove PU composition.
π£ Immediate Action:
π Contact your customs broker with Product Specs (Material, Rigidity, Length).
π Apply for Advance Ruling if you have large, recurring shipments of mixed rigid/flexible PU hoses.

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