What decides the code
Steel wood screws are threaded fasteners of iron or steel and are classified under heading 7318, specifically subheading 7318.12.00.00 for other wood screws.
- Material of iron or steel places the screw in heading 7318, which covers threaded fasteners of those metals.
- The screw is threaded, so it falls under the threaded articles of 7318 rather than unthreaded articles.
- It is a wood screw, which directs classification to subheading 7318.12.00.00 within heading 7318.
Common mistakes
- Classifying steel wood screws under 7318.15 as other screws and bolts is wrong because 7318.12 covers wood screws specifically.
- Putting steel wood screws in heading 7317 for nails and tacks is wrong because those articles are not threaded fasteners.
- Classifying steel wood screws under 7326 as other articles of iron or steel is wrong because heading 7318 covers threaded screws.
