What decides the code
Steel twist drill bits are interchangeable drilling tools classified under heading 8207, specifically subheading 8207.50.20.55 for twist drills with a cutting part containing chromium, molybdenum, or tungsten above the specified threshold.
- The tool is an interchangeable drill bit for hand or machine tools, which places it in heading 8207.
- The bit is for drilling, not rock drilling, which leads to subheading 8207.50.
- The cutting part contains chromium, molybdenum, or tungsten above the weight threshold, which leads to 8207.50.20.
- The bit is a twist drill, which leads to the statistical suffix 8207.50.20.55.
Common mistakes
- Classifying steel drill bits under 8207.50.40 as masonry drills is wrong because these bits are for metal or general drilling, not rock drilling.
- Using 8207.90 for drill bits is wrong because 8207.90 covers other interchangeable tools, not drilling tools.
- Classifying drill bits under 8206 is wrong because 8206 covers sets of tools for retail sale, not individual drill bits.
