📌 I. Product Definition & Classification: What Exactly Is a "Plastic Pipe Cap"?

A Plastic Pipe Cap is a critical piping component used to seal the open end of a pipe, preventing the entry of debris, water, or air, and containing internal pressure. In international trade, these are classified based on their material composition and functional role within the piping system.

1. Plastic Pipe Fittings (General):
Standard caps made from polyethylene (PE), polypropylene (PP), PVC, or ABS that serve as generic pipe accessories.
2. Other Plastic Accessories:
Caps that do not fit standard fitting definitions but still function as plastic pipe components.

⚠️ Key Distinction:
- If it is a standard plastic fitting designed to connect or seal pipes →归入 3917.40.00.50
- If it is categorized broadly as a plastic accessory without specific fitting classification →归入 3917.40.00.95

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Key Reminder:
- Both codes fall under Chapter 39 (Plastics) and Heading 3917 (Pipes and Tubes).
- The difference lies in the specificity: 50 is for standard fittings; 95 is the "basket" code for other plastic pipe accessories.
- Do NOT mix with metal caps (see below).
