💡 Electric Portable Dental Floss Water Jet (Oral Irrigator)

🌐 HS Code Classification & Customs Clearance Guide | 2026 Updated Tariff Analysis | Pro Tips for Smooth Import
📌 One Product, Multiple HS Codes — Know Which One Applies to Your Shipment!

📌 I. Product Definition & Classification: What Exactly Is an Electric Portable Dental Floss Water Jet?

An electric portable dental floss water jet is a battery-powered, handheld device that uses pulsating water pressure to clean between teeth and below the gumline. It's designed for personal oral hygiene, commonly used at home or while traveling.

⚠️ Key Features That Define Its Classification: - Electric motor-driven (contains a built-in motor) - Portable & battery-operated (not mains-powered) - Used for dental cleaning (not general household cleaning) - Specifically designed for oral hygiene — not a general sprayer or cleaner

🔍 Why This Matters:
The functional purpose and intended use are critical. If it’s marketed and used for dental care, it falls under dental instruments, not general cleaning tools.

📦 II. HS Code Breakdown (2026 Latest Tariff Authority)

✅ Bottom Line:
- If intended for dental care, use 9018.49.80.80, 9018.41.00.00, or 9018.49.80.40
- If misclassified as a general sprayer or toothbrush, you risk much higher tariffs.

🎯 5. 8509.80.50.45 — Electric Household Appliances (With Motor)
