How Much Does the UL 499 Test Cost?

Hand warmers and heating appliances are widely used in cold weather. They can be placed in pockets to keep hands warm while walking or exercising outdoors. Indoors, they can provide warmth when there is no heating or when it feels cold, especially for people whose hands get cold easily, such as the elderly and women.

So, what certifications are required for electric heating devices/hand warmers to be exported to the United States?

Required Certifications for Exporting Electric Heating Devices/Hand Warmers to the U.S.:

FCC Certification

FCC certification is a mandatory requirement by the U.S. Federal Communications Commission for electronic products. It primarily regulates the electromagnetic compatibility of products to ensure they do not cause harmful interference to other electronic devices during normal use and that they can also resist a certain level of external electromagnetic interference.

Applicable Scope:

FCC certification applies to most electronic and electrical products that emit radio frequencies. If hand warmers and other electric heating devices contain electronic components, such as control circuits, they generally require FCC certification.

fcc testing Items:

- Radio frequency emission test

- Conducted emission test

- Radiated immunity test

These tests ensure that the product’s electromagnetic radiation and interference resistance meet FCC standards and requirements.

UL certification

UL certification, issued by Underwriters Laboratories, is a safety certification for products. Although it is not a mandatory certification, it is highly recognized in the U.S. market and is considered a key requirement for product entry. It demonstrates that the product meets high safety and compliance standards.

Applicable Scope:

UL certification covers a wide range of fields, including electronic products, household appliances, and industrial equipment. When conducting UL certification for electric heating devices/hand warmers, relevant UL standards such as UL 499 must be followed.

UL 499 Testing Items:

- Leakage current test

- Input test

- Leakage current test under humid conditions

- Normal temperature rise test

- High voltage resistance test

- Stability test

- Dry burn test

- Abnormal condition test

- Static pressure and strength test

- Fuse test

- Power cord pull test

- Thrust test

- Plastic deformation test

- Impact test

- Water spill test

- Ground resistance test

- Waterproof gasket aging test
