Product classification
HS code for Door locks: 8301.40
Locks, (other than those for motor vehicles or furniture), (key, combination or electrically operated), of base metal.
Classification of door locks under HS 8301.40
Door locks are classified under HS code 8301.40 because they are identified as locks of base metal that are not specifically designed for use in motor vehicles or furniture. This classification falls under Chapter 83, which covers miscellaneous articles of base metal. According to the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1, classification is determined by the terms of the headings and any relative section or chapter notes. Heading 8301 covers padlocks and locks (key, combination, or electrically operated), of base metal. Subheading 8301.40 is a specific category for "other locks," which includes those used for doors of buildings. The classification remains consistent regardless of whether the lock is a traditional mechanical key lock or a modern electronic version, provided the primary component and function remain that of a base metal lock. If the lock is integrated into a larger security system with sensors and alarms, it might require a different classification, but standard door-mounted locks for residential or commercial buildings are firmly placed here.

Codes often confused with 8301.40
Common mistake. Door locks are frequently confused with HS code 8301.20, which is reserved specifically for locks used in motor vehicles, or HS code 8301.30, which is for locks used in furniture. Another common error is classifying electronic smart locks under HS code 8531.10 (burglar or fire alarms and similar apparatus) or HS code 8543.70 (other electrical machines and apparatus). However, if the primary function is the mechanical locking of a door, 8301.40 remains the correct classification.

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).
