🧪 LDPE Fittings (Low-Density Polyethylene Fittings) – Complete HS Code & Customs Guide 2026
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Breakdown | Professional Logistics Strategy
📌 I. Product Definition & Classification: What exactly are "LDPE Fittings"?
LDPE Fittings (Low-Density Polyethylene Fittings) are specialized connection components used in plastic piping systems. They include joints, elbows, tees, couplings, flanges, and adapters made from Low-Density Polyethylene (LDPE).
In international trade, they are strictly distinguished from the raw plastic material:
- Raw Material (Polyethylene Pellets/Resin): The plastic granules used for manufacturing (e.g.,
3901.10.50.xx). NOT the final fitting. - Finished Fittings: The final shaped components ready to connect pipes, hoses, or tubes.
- Key Distinction: If the item is a raw polymer in primary forms (pellets, granules), it belongs to Chapter 3901. If it is a finished article shaped for connection (e.g., a 90° elbow), it belongs to Chapter 3917.
⚠️ Critical Clearance Point: * If you import pellets to make your own fittings → HS Code:
3901.10.50.xx(Tax: 0.0%). * If you import pre-made fittings → HS Code:3917.40.00.xx(Tax: 0.0% for most, but Watch out for "Plumbing" vs. "Other"). * Do NOT misclassify finished fittings as "raw materials" to evade duties; Customs will reject this immediately.
📦 II. HS Code Classification Details (2026 Tariff Authority)
Based on the provided data, here are the precise classifications for LDPE Fittings and related polymers:
| HS Code | Product Description | Category | Specific Sub-type | Applicable Scenario | | :--- | :--- | :--- | :--- :--- | | 3917.40.00.95 | Tubes, pipes and hoses and fittings therefor... of plastics: Fittings Other | Fittings | Other plumbing fittings: Other | General purpose LDPE fittings (not strictly "plumbing" in the strict sense, or generic "Other" category). | | 3917.40.00.80 | Tubes, pipes and hoses and fittings therefor... of plastics: Fittings Other plumbing fittings: Other | Fittings | Plumbing Fittings | LDPE fittings specifically used for plumbing (water supply, drainage, irrigation). | | 3901.10.50.20 | Polymers of ethylene...: Polyethylene...: Other Low density polyethylene, except linear low density polyethylene | Raw Material | LLDPE Exclusion (LDPE) | NOT FITTINGS! This is the raw LDPE resin/pellets. Used to make fittings. | | 3901.10.50.10 | Polymers of ethylene...: Polyethylene...: Other Linear low density polyethylene | Raw Material | LLDPE | NOT FITTINGS! This is raw LLDPE resin. (Sometimes confused with LDPE in procurement). | | 3926.30.50.00 | Other articles of plastics...: Fittings for furniture, coachwork or the like: Other | Misc Fittings | Furniture/Coachwork | DO NOT USE for piping unless the "fitting" is actually a furniture connector. | | 3926.90.99.89 | Other articles of plastics...: Other: Other Other | Misc Plastics | Catch-all Category | HIGH RISK. Only use if the fitting does not fit 3917 (e.g., weird shape). |
🔍 Key Insight: * 3917.40.00.80 & 3917.40.00.95 are the correct codes for actual pipe fittings. * 3901.10.50.20 is the code for the LDPE raw material. Importers often confuse "LDPE Fittings" with "LDPE Material". * 3926.90.99.89 carries a 12.8% total tax. Avoid this for standard pipe fittings if possible, as it is a "Other" catch-all with higher duties.

🛠️ IV. Clearance & Logistics Strategy (Actionable Advice)
✅ 1. Preparation Checklist (Non-Negotiable)
| Document | Requirement | Why? |
|---|---|---|
| ✅ Technical Specification Sheet | Must state: "LDPE", "Low Density", "For Pipe Fitting Use". | Proves the material and function to Customs. |
| ✅ Commercial Invoice | Description: "LDPE Elbow/Joint for Piping". Avoid vague terms like "Plastic Part". | Vague terms trigger audits and potential re-classification to 3926.90.99.89. |
| ✅ Photos of Product | Clear shots of the fitting (not just pellets). Show connection ports. | Visual proof that it is a "Fitting" (3917) and not "Raw Material" (3901) or "Misc Part" (3926). |
| ✅ Material Certificate (MSDS/Spec) | Confirm Specific Gravity < 0.94 (LDPE characteristic). | Confirms it is LDPE, not HDPE (which might have different codes). |
✅ 2. Declaration Strategy (The "Golden Rule")
🔥 Rule: "Function First, Material Second, Shape Third!"
| Scenario | Correct Declaration | Wrong Declaration | Consequence |
|---|---|---|---|
| Standard Pipe Elbow | HS: 3917.40.00.80 (Plumbing) |
HS: 3926.90.99.89 (Other) |
Pay 12.8% extra tax! |
| Raw LDPE Pellets | HS: 3901.10.50.20 |
HS: 3917.40.00.95 |
Risk of Seizure (Wrong category). |
| Furniture Connector | HS: 3926.30.50.00 (If for furniture) |
HS: 3917.40.00.95 |
Audit Risk (Misuse of HS). |
| Generic "Plastic Connector" | HS: 3917.40.00.95 |
HS: 3926.90.99.89 |
Pay 12.8% instead of 0%. |
💡 Pro Tip: Use the phrase "Plastic Fittings for Pipes/Tubes" in the description field. This automatically aligns with Chapter 3917.
✅ 3. Special Scenarios & Solutions
| Situation | Solution |
|---|---|
| "Is my fitting 'Plumbing' or 'Other'?" | If it connects to water/gas pipes → 3917.40.00.80. If it's for industrial hoses not in plumbing → 3917.40.00.95. Both are 0%. |
| "My fitting is LLDPE, not LDPE." | Check the material certificate. If LLDPE, the raw material code is 3901.10.50.10. But the fitting is still 3917. Material type doesn't change the fitting code, only the raw material code. |
| "Customs rejected my 'Other' claim." | If you used 3926.90.99.89, immediately re-declare to 3917.40.00.95 or .80. The 12.8% tax is unnecessary for fittings. |

📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Mistake 1: Calling it "Plastic Connector" instead of "Pipe Fitting".
👉 Result: Customs may classify as 3926.90.99.89 (12.8%).
✅ Fix: Always use "Fittings for pipes/tubes/hoses" in the description.
❌ Mistake 2: Confusing LDPE Resin (3901) with LDPE Fittings (3917).
👉 Result: If you ship pellets but call them fittings, you fail inspection. If you ship fittings but call them resin, you misclassify.
✅ Fix: Separate raw material shipments from finished goods shipments.
❌ Mistake 3: Not specifying "Plumbing" when applicable.
👉 Result: Minor risk, but 3917.40.00.80 is more precise than .95 for water pipes.
✅ Fix: Use .80 for water/gas plumbing; use .95 for industrial/general hose fittings.
🎯 VII. Final Verdict: The "Zero Duty" Strategy

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
