What decides the code
A blood pressure monitor is a sphygmomanometer classified in heading 9018, and the upper arm unit falls under 9018.90.50.40.
- The product measures blood pressure, which makes it a sphygmomanometer of heading 9018.
- It is an electro-medical instrument used in medical science, so heading 9018 covers it rather than a general measuring heading.
- The upper arm design is a sphygmomanometer with its parts and accessories, which leads to 9018.90.50.40.
Common mistakes
- Classifying the monitor under 9027 as a measuring instrument is wrong because heading 9018 covers medical instruments and appliances.
- Putting the unit in 9018.19 as electro-diagnostic apparatus is wrong because a blood pressure monitor measures pressure rather than diagnosing electrical activity.
- Treating the cuff as a separate textile article is wrong because the cuff is a part or accessory of the sphygmomanometer and follows heading 9018.
