Radio Frequency Testing

1. Introduction to Certification

As Amazon's strategic position in global business continues to improve, live products on Amazon require relevant UL reports, and test reports issued by ISO 17025-qualified laboratories are required for normal sales and link recovery. If the products purchased by competitors or customers do not have the relevant standard safety report, the competitors or customers will entrust a US lawyer to send a letter to Amazon, requesting to stop selling the company’s products, and apply for court procedures to destroy all the company’s products on Amazon , which may mean that the company is basically driven out of the North American market. Many sellers reported that they received relevant email notifications, and because the products could not provide the UL test report within the specified time, there were problems such as suspension of sales and listing being removed from the shelves.

The difference between UL certification and UL test report

UL certification: voluntary certification, which needs to test products and audit factories, and audits are conducted once a quarter. The cost is high, the time is long, and the audit factory is very strict.

UL test report: According to the product selection of the corresponding UL standard for testing, a qualified test report will be issued. The cost is low, the cycle is short, and no factory audit is required. Can be used for Amazon review, customs clearance is invalid.
