🧪 Plastic Test Tube Rack

🌐 HS Code Reference & Customs Clearance Guide | 2026 Updated Tariff Analysis | Professional Import Strategy
📌 One, Product Definition & Classification: What Exactly Is a "Plastic Test Tube Rack"?

A plastic test tube rack is a laboratory accessory designed to hold, organize, and stabilize test tubes during experiments, storage, or transport. It is typically made from plastic (e.g., polypropylene, polystyrene) and features a fixed or adjustable grid layout to securely fit standard-sized test tubes (e.g., 13mm, 16mm, 20mm diameter).

⚠️ Key Classification Point:
- If the rack is used solely as a holder for test tubes and not part of a larger instrument system, it is not a measuring device or analytical tool.
- It is considered a supporting or fixing component for laboratory use — not a primary instrument.

📦 Two, HS Code Classification Details (2026 Updated Tariff Authority)

🔍 Critical Insight:
- Plastic test tube racks are NOT lab instruments — they are accessories or support fixtures.
- They cannot be classified under 7017.90.50.00 (which applies to glass/metal lab stands) unless they are made of glass or metal.
- Plastic racks must be classified under 3917 or 3926 — depending on whether they are pipe/tube fittings or general plastic parts.

👉 Result: Pay duty unnecessarily — can save 100%.

❌ Mistake 4: Declaring as "lab equipment" or "instrument"
