Product classification
HS code for Security locks: 8301.40
Locks, (other than those for motor vehicles or furniture), (key, combination or electrically operated), of base metal.
Classification of security locks under HS 8301.40
Security locks are classified under HS code 8301.40, which encompasses "other locks" made of base metal. This classification is determined by the primary function of the device—providing a mechanical or electromechanical locking mechanism—and its material composition. Chapter 83 of the Harmonized System covers miscellaneous articles of base metal, and heading 8301 specifically addresses padlocks and locks (key, combination, or electrically operated). Subheading 8301.40 is a specific category for locks that are not designed for motor vehicles (8301.20) or furniture (8301.30). Modern security locks, including electronic smart locks, biometric deadbolts, and digital keypad entries, remain under this code provided they incorporate a mechanical locking bolt or latch made of base metal. The classification follows GRI 1, as the product is specifically named in the heading, and GRI 3(b) for composite goods where the mechanical locking function provides the essential character of the security device.

Codes often confused with 8301.40
Common mistake. A frequent misclassification occurs with HS code 8543.70, which covers electrical machines and apparatus. Importers often mistakenly use this for smart locks; however, if the device has a mechanical locking component, 8301.40 takes precedence. Additionally, padlocks are often confused with this code but must be classified under 8301.10. Locks specifically for motor vehicles must be declared under 8301.20, and those for cabinets or desks under 8301.30.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
