What decides the code
A HEPA air purifier is filtering machinery for gases under heading 8421, classified at 8421.39.01.15 as dust collection and air purification equipment.
- The product filters air, a gas, so it falls under heading 8421 for filtering or purifying machinery and apparatus for gases.
- It is dust collection and air purification equipment, which places it in the statistical line 8421.39.01.15.
- The HEPA filter is the purifying element, so the unit is classified as gas filtering apparatus, not as a fan or household appliance.
Common mistakes
- Classifying under 8414 as a fan is wrong because the fan only moves air, and the purifying function gives the unit its essential character.
- Classifying under 8479 as other machinery is wrong because heading 8421 specifically covers filtering and purifying apparatus for gases.
- Classifying under 8509 as a household appliance is wrong because that heading covers electro-mechanical domestic appliances, not air purifying equipment.
