What decides the code
Dental floss is yarn used to clean between the teeth, classified under heading 3306 in HTSUS line 3306.20.00.00 when put up in individual retail packages.
- The product is yarn used to clean between the teeth, which places it in heading 3306 as dental floss.
- It is put up in individual retail packages, the form described in heading 3306 for dental floss.
- Floss sold in bulk or on industrial reels without retail packaging does not fit the retail package description of 3306.20.00.00.
Common mistakes
- Classifying floss under 3306.10 as toothpaste or dentifrice is wrong because that line covers pastes and powders, not yarn for cleaning between teeth.
- Putting floss in 5601 or another textile yarn heading is wrong because heading 3306 specifically names dental floss in retail packages.
- Treating floss as a medical or surgical article under Chapter 90 is wrong because it is an oral hygiene preparation, not an instrument.
