What decides the code
A smart door lock is a base metal lock of heading 8301, classified under 8301.40.60.30 as a door lock suitable for interior or exterior doors.
- The lock body is of base metal, which places it in heading 8301.
- It is an electrically operated lock, which heading 8301 covers along with key and combination locks.
- It is designed for mounting on an interior or exterior swing door, which leads to 8301.40.60.30.
- A lock built for garage, overhead or sliding doors falls outside this line and takes a different door lock line.
Common mistakes
- Classifying under 8301.40.60.30 when the lock is made for sliding or overhead doors, which are excluded from this line.
- Treating the electronic keypad or app module as the whole article under a separate electrical heading, when the base metal lock body governs classification in 8301.
- Using a padlock line in 8301 for a lock that mounts on a door, since padlocks are separate from door locks.
