According to the evidence provided by the applicant and the preliminary review by the Ministry of Commerce, the total production of the applicant's relevant analog chips meets the qualifications stipulated in the Anti-Dumping Regulations of the People's Republic of China. Additionally, the application included the required content and relevant evidence for the initiation of the anti-dumping investigation as stipulated in Articles 14 and 15 of the Anti-Dumping Regulations of the People's Republic of China.

Based on the above review results, and in accordance with Article 16 of the Anti-Dumping Regulations of the People's Republic of China, the Ministry of Commerce decided to initiate an anti-dumping investigation on imported relevant analog chips originating from the United States starting from September 13, 2025. The relevant matters are hereby announced as follows:

1. Initiation of Investigation and Investigation Period

From the date of publication of this announcement, the Ministry of Commerce will conduct an anti-dumping investigation on imported relevant analog chips originating from the United States. The dumping investigation period determined for this investigation is from January 1, 2024, to December 31, 2024, and the industry damage investigation period is from January 1, 2022, to December 31, 2024.

1. Products Under Investigation and Scope of Investigation

Scope of Investigation: Imported relevant analog chips originating from the United States.

Name of the investigated product: Relevant analog chips.

English Name: Certain Analog IC Chip.

Product Description and Main Uses: Relevant analog chips that use 40nm and above process technology, including Commodity Interface IC Chips and Gate Driver IC Chips.

Among them:

Commodity Interface Chips are integrated circuit chips designed to provide a variety of interface types for connecting various devices, systems, or components to achieve efficient data transmission and signal conversion. The investigated Commodity Interface Chips include:

1. Controller Area Network (CAN) interface transceiver chips that comply with ISO11898 standards, used for sending and receiving signals between systems in automobiles and other industrial products;

2. RS485 transceiver chip that complies with TIA/EIA-485 standards, used for signal transmission and reception between various devices in industrial systems;

3. Bidirectional two-wire synchronous serial bus (I2C) interface chip made based on low-speed serial bus using serial data lines and serial clock lines, used for switching and extending signal buffering relay channels between various boards or chips in devices;

4. Digital isolator chip that complies with the International Electrotechnical Commission IEC 60747-5-2 standard, used for insulated communication between high and low voltage systems in automotive and other industrial products, or to enhance communication anti-interference performance;

5. Other general-purpose interface chips that are compatible with the above types.

Gate driver chips are integrated circuit chips used to enhance the gate control signal output of controllers, controlling the conduction and cutoff of power semiconductor devices. Gate driver chips provide the necessary voltage and current levels to effectively turn these semiconductor switches on and off, thereby achieving power conversion and control. The investigated gate driver chips include:

1. Low-Side Gate Driver IC Chip;

2. Half-Bridge/Multi-Channel Gate Driver IC Chip;

3. Isolated Gate Driver IC Chip.

The investigated gate driver chips have the following functions: 1. Converting the low-voltage signals from the controller into higher voltage or larger current drive signals to achieve stable conduction and cutoff of power devices; 2. Providing transient pull and sink currents to improve the switching speed of power devices and reduce switching losses.

The investigated general-purpose interface chips and gate driver chips include finished chips as well as wafers and die that can be used to produce chips with the same functions, as well as products with the same functions developed in the future.

This product falls under the "Import and Export Tariff of the People's Republic of China": 85423990. Other products under this tariff item are not included in this investigation.
