Class 1 or A
Class 1 are goods that have at least legal control. The level of impact and risk of these devices is minimal on people and they are simpler than other classroom products. For such goods there should be "general controls". General Contains:
- Registration and specifications of the manufacturer distributor re-packagers and companies that make changes to the device's symptoms in the US Food and Drug Administration
- Register a product that is ready for sale at the US Food and Drug Administration
- Production of the device in accordance with the principles of "good production conditions"

Class 2 or B
Class 2 are goods that are not only "general controls" to ensure their quality is not enough and some special controls should be made on them. Few of these devices are exempted from pre-sale notice. These special controls may include special labeling requirements performance standards and after-sales monitoring. Items like a hot water bottle and in some countries mats are placed in this category.
Class 3 or C
The most sensitive devices with hard-facing controls are in this category. In this category there are goods that the patient's life depends on their proper functioning. These devices have a huge impact on the diagnosis control or treatment of the disease. These tools do not need to be announced before they are sold. The quality assurance of these products is not met with general controls and requires a lot of scientific experiments and research. Items like a barometer a thermometer a heart rate monitor and advanced hospital equipment in this group.
