18 piece Quick Connector Set

🔌 18-Piece Quick Connector Set (Hydraulic/Pneumatic Fittings)

🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 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.

⚠️ Key Distinction:
- If the set is primarily plastic plumbing or general-purpose fittings → 3917.40
- If the set is metal (iron/steel) articles, not specifically tube supports → 7326.90
