【Reese’s Law】Household Products with Built-In Button Batteries Must Comply with UL4200A Testing Requirements

In a proactive measure to prevent injuries and fatalities among children caused by accidental ingestion of button batteries, the U.S. government has enacted legislation known as Reese’s Law on September 21, 2023, set to take effect from March 19, 2024. Products incorporating button batteries and intended for use in general household environments are mandated to adhere to the product safety regulations outlined in UL4200A before being imported into the United States.

Wendell Electrical Testing Co., Ltd. stands ready with UL4200A testing capabilities and is well-equipped to conduct relevant tests for your products. This ensures that your products can be deployed ahead of the mandatory decree date (March 19, 2024), allowing you to ship with confidence.

Wi-Fi 6E new news by NCC

MINISTRY OF DIGITAL AFFAIRS Notice is hereby given, for the amendment of “Radio Frequency Supply Plan” (amendment becomes effective from 25th, August 2023)

○Announcement of 5945-6425MHz for Wi-Fi 6E use.


Technical specification for Low Power Radio Frequency Devices LP0002 is under revision and will be published by the end of 2023.


Before the 5945~6425MHz band is incorporated into LP0002, or LAB/RCB has not been accredited by TAF, NCC issues approval certificates through two-stage inspection with test reports issued according to the latest version of ETSI EN 303 687 V1.1.1.

BSMI will adopt CNS15936:2016

BSMI will adopt the latest version of the electromagnetic compatibility inspection standard, CNS15936:2016 to ensure consumers’ safety.

NCC certification update antenna data request

NCC Conformance Meeting – Conclusion No. 11112502

The requirements for NCC certification antenna data have been updated (refer to FCC requirements). The NCC certification should submit antenna specification technical documents or antenna test reports (Antenna Test Report, AUT Report)

According to FCC KDB 353028 and FCC TCB Work Shop Part 15 Antenna Update on October 26, 2022.

Antenna datasheet needs to indicates following information:

manufacturer name/address, antenna type, brand, model, operating frequency band and Gain value, 2D or 3D diagrams, antenna photos or drawings, etc.

Report and Order 22-84 – FCC requiring two new attestation statements to be provided

On November 25, 2022, the commission adopted new FCC requirements to protect the nation’s networks and supply chains from equipment (“covered” equipment). The new rules provide a permanent prohibition to process/grant entities listed on the FCC Covered List.

Covered List:https://www.fcc.gov/supplychain/coveredlist


On January 24, 2023, the FCC Published KDB 986446. TCBs are expected to exercise appropriate diligence to prohibit granting of “covered” equipment. All FCC Equipment Authorizations granted by TCB’s henceforth, need to include the following two attestation letters:


On February 6, 2023, the final rules were published in the Federal Register and are, therefore, effective from today.

UKCA issued the newest “Guidance – Placing manufactured products on the market in Great Britain” – Prototypes and testing samples do not require UKCA marking.

Prototypes which are not yet made available for distribution, consumption or use on the GB market do not require UKCA marking. However, the prototype must only be displayed or demonstrated under controlled conditions at trade fairs or exhibitions in GB. This means the product needs to be operated by experts, there must be restricted public contact with the product, the product must not interact inappropriately with other neighbouring products, and it must be clearly indicated on a sign that the product does not meet the GB requirements and will not be made available until it does.

Products undergoing testing or validating pre-production of units do not require UKCA marking. They are still considered to be in the stage of manufacture and therefore have not been placed on the GB market.

However, fully manufactured products intended for consumer testing need to meet the UK requirements as they apply in GB at the time the consumer testing takes place.

UKCA updated

The deadline for when businesses need to use the UKCA mark has been extended. All goods which previously required the CE marking can continue to use the CE marking until 31 December 2024.

China MIIT issued the notices of updated technical requirement for wireless devices that operate at the bands of 2400MHZ, 5100MHZ and 5800MHZ on Oct. 13th, 2021.

China MIIT issued the notices of updated technical requirement for wireless devices that operate at the bands of 2400MHZ, 5100MHZ and 5800MHZ on Oct. 13th, 2021.  In order to increase the compatibility between wireless devices and facilitate more efficient of frequency resource, from Jan. 1st, 2022, China SRRC approval will require the adaptivity (Channel Access Mechanism) testing. Referring to the clause 4.2.7 of EN 301 893, this will require complicated setting of testing environment and normally require repeated debugging procedure. Consequently, testing time and cost will be increased thereafter.

UKCA last updated

All goods which previously required the CE marking will not need to use the UKCA marking until 1 January 2023.


Businesses are encouraged to be ready for full implementation of the new UK regime as soon as possible. However, to allow businesses time to adjust, CE marked goods in scope that meet EU requirements (where these match UK requirements) can continue to be placed on the GB market until 1 January 2023 where EU and UK requirements remain the same. This includes goods which have been assessed by an EU recognised notified body.

The UKCA mark must be used for placing goods on the GB market from 1 January 2023.
