🦷 Tooth Trays (Dental Appliances)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand “Tooth Trays”?

Tooth trays, also known as dental splints, retainers, or custom mouthguards, are critical auxiliary devices in dentistry. In international trade, their classification depends heavily on material composition and specific medical purpose. They generally fall into two main categories:

1. Medical/Prosthetic Devices: Made of synthetic materials specifically for dental treatment, protection, or filling. These typically fall under Chapter 90 (Optical/Medical Instruments).
2. Plastic/Resin Articles: Generic plastic成型制品 (molded articles) not specifically designed as medical instruments. These fall under Chapter 39 (Plastics).

⚠️ Key Distinction Point:
- If the product is explicitly described as a dental accessory, prosthetic part, or medical protective device made of plastic/resin → It leans towards Chapter 90 (9021) or Chapter 30 (3006).
- If the product is a generic plastic molded article without specific medical device certification or detailed dental function description → It leans towards Chapter 39 (3926).

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

Based on the provided data, here are the potential HS codes and their logical justifications:

🔍 Critical Analysis:
- Lowest Tax (10.0%): Applies if the product is correctly classified as a medical/dental device (9021 or 3006). This requires proving its specific medical/dental function.
- Highest Tax (38.5%): Applies if classified as a generic plastic product (3926). This often happens if the medical nature is not clearly documented or if the material is deemed non-specialized plastic.
- Mid-Tax (22.8%): Another "plastic" classification but with different specific subheadings.

👉 Consequence: Customs may doubt the medical classification and default to 3926 → 22.8% Tax!
