π 18-Piece Quick Connector Set (Hydraulic/Pneumatic Fittings)
π HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
π I. Product Definition & Classification: Do You Really Understand "Quick Connectors"?
An "18-Piece Quick Connector Set" typically refers to a kit containing various hydraulic or pneumatic fittings (such as couplings, adapters, elbows, and tees) used for rapid connection of tubes, pipes, or hoses. These are plastic or metal components designed to join fluid/power transmission lines without tools.
In international trade, the classification depends heavily on the material and the specific function: * Plastic Fittings: If the connectors are made of plastic (e.g., for low-pressure air/water applications), they fall under Chapter 39. * Metal Fittings: If the connectors are made of iron or steel (e.g., for high-pressure hydraulics), they fall under Chapter 73.
β οΈ Key Distinction:
- If the set is primarily plastic plumbing or general-purpose fittings β 3917.40
- If the set is metal (iron/steel) articles, not specifically tube supports β 7326.90
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided <DATA>, here are the applicable HS Codes for an "18-Piece Quick Connector Set":
| HS Code | Product Description | Applicable Scenario | Material | Contains Support Functions? |
|---|---|---|---|---|
3917.40.00.95 |
Fittings of plastics: Fittings Other | General plastic hydraulic/pneumatic connectors not specifically for DWV | Plastic | β No |
3917.40.00.50 |
Fittings of plastics: Fittings Plumbing fittings, not pressure rated (DWV) | Low-pressure plastic drain/waste/vent connectors | Plastic | β No |
7326.90.86.88 |
Articles of iron or steel: Other: Other: Other: Other | Metal quick connectors (hydraulic/pneumatic) not classified elsewhere | Iron/Steel | β No |
7326.90.86.30 |
Articles of iron or steel: Hangers and similar supports for tubes and pipes | Metal supports/clamps for tubes (rare for "quick connectors" unless they are mounting brackets) | Iron/Steel | β Yes |
π Critical Reminder:
- Plastic Quick Connectors: Most "quick connector sets" for air/water tools are plastic. Use3917.40.00.95unless they are explicitly DWV (Drain/Waste/Vent) items, then use3917.40.00.50.
- Metal Quick Connectors: If made of steel/iron, they are generally classified as "Other articles of iron or steel" (7326.90.86.88).
- Avoid7326.90.86.30: This code is for hangers/supports, not the connectors themselves, unless the set is exclusively mounting brackets.

π οΈ IV. Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Required | Notes |
|---|---|---|
| β Product Spec Sheet | βοΈ | Must specify material (Plastic vs. Metal) and pressure rating |
| β Commercial Invoice | βοΈ | Clearly state "Quick Connector Set" and list individual piece types |
| β Packing List | βοΈ | Detail the 18 pieces (e.g., 6 couplers, 6 adapters, 6 tees) |
| β Material Declaration | βοΈ | CRITICAL: Declare "Plastic" or "Steel" explicitly to avoid misclassification |
| β Certifications | βοΈ | If plastic: RoHS/REACH; If metal: Material Test Report (MTR) |
β 2. Classification Strategy (Key Mantra)
π₯ βPlastic is Free, Steel is Expensive β Declare Material Correctly!β
| Scenario | Correct HS Code | Duty Rate | Mistake Consequence |
|---|---|---|---|
| Plastic Quick Connectors (Air/Water tools) | 3917.40.00.95 |
0.0% | Misdeclaring as metal β 77.9% duty + penalties |
| Plastic DWV Fittings (Drainage) | 3917.40.00.50 |
0.0% | Misdeclaring as other β Unnecessary scrutiny |
| Steel Quick Connectors (Hydraulics) | 7326.90.86.88 |
77.9% | None (mandatory) |
| Steel Mounting Brackets | 7326.90.86.30 |
77.9% | Misdeclaring as fittings β Same rate, but different description |
π Expert Tip:
- If your "Quick Connector Set" contains both plastic and metal parts, split the shipment or declare separately.
- Do not mix plastic and metal in one HS Code line item unless instructed by customs.
- Plastic parts can enjoy 0% duty, significantly reducing average cost.
β 3. Special Case Handling
| Case | Recommendation |
|---|---|
| OEM Custom Sets | Provide design drawings showing material composition. |
| "Hydraulic" vs. "Pneumatic" | Material matters more than pressure. Steel hydraulics = 77.9%; Plastic pneumatics = 0%. |
| Mixed Kits | Separate plastic and metal components on the invoice. Declare plastic under 3917 and metal under 7326. |
| De Minimis ( <$800) | Plastic sets under $800 may enter duty-free. Steel sets under $800 may still face scrutiny or duties depending on carrier policy. |

β Mistake 2: Declaring Plastic Connectors as "Metal Fittings"
π Consequence: Overpaying duties (0% vs 77.9%) β Lost profit margin
β Mistake 3: Mixing DWV (Drain) and Pressure fittings in one line item
π Consequence: Customs may reject the classification or apply the higher duty rate
β Mistake 4: Ignoring the Steel/Aluminum Surcharge for metal parts
π Consequence: Unexpected 77.9% duty bill at customs
β Correct Declaration Example:
"Plastic Quick Connector Set, 18 Pieces, for Pneumatic Air Tools, Material: Nylon/Polycarbonate, Not for Drain/Waste/Vent"
β HS Code:3917.40.00.95β 0% Duty
π― VII. Conclusion: Smart Classification, Maximum Savings!
π― Remember the Mantra:
πΉ "Plastic = Free, Steel = 77.9% β Declare Material First!"
πΉ "Separate Kits if Mixed, Save Thousands in Duties!"
π Pro Tip:
If your product is plastic, ensure your invoice clearly states "Plastic" and "Not for DWV" (if not DWV) to lock in 0% duty.
If your product is steel, consider re-sourcing from non-China countries to avoid the 77.9% surcharge, or negotiate costs with your customer.
π£ Immediate Action:
π Verify material composition with your supplier.
π¦ If plastic, declare under3917.40.00.95.

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
