🛠️ Door Chain (Chain for Door Locks)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Updated Tariff Analysis | Professional Import Strategy
📌 One, Product Definition & Classification: Do You Really Understand “Door Chain”?

A door chain is a metal security accessory used to reinforce door safety by allowing the door to be opened slightly while maintaining a secure barrier. It is commonly used in residential, commercial, and industrial buildings to prevent unauthorized entry while enabling controlled ventilation or communication.

In international trade, door chains are classified under metal lock fittings, and their classification depends on: - Material: Typically steel, iron, or aluminum - Form: Non-threaded metal component (not a fastener) - Function: Used as a door security device, not a standalone lock

⚠️ Key Differentiation:
- If it’s a chain used with a door lock mechanism, it’s considered a lock accessory → 8302.41.90.15
- If it’s a metal rod or bolt with threads, it may fall under fasteners → 7318.19.00.00
- If it’s a non-threaded metal fitting for a lock system → 8301.40.60.60 or 8301.40.60.30

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

🔍 Critical Insight:
- Door chains are not classified as fasteners (like screws or bolts) unless they are threaded.
- Even if they look like a chain, if they are non-threaded and used as part of a lock system, they fall under lock accessories → 8302.41.90.15 or 8301.40.60.60
- Do not misclassify door chains as fasteners (7318.xxxx) — this leads to incorrect tariffs and penalties.

- No Section 301 (USITC) duty applies to this code — it’s not on the Section 301 list. - IEEPA 10% applies to all Chinese-origin goods under this category. - No 50% steel/aluminum duty applies here because door chains are not classified as steel/aluminum/copper products under the 50% add-on rule. - Total: 13.5% — relatively low, but still subject to IEEPA 10%.
