The Standard Industrial Classification (SIC) code system is a method for classifying industries by a four-digit code. For electronic products, the specific SIC code can vary depending on the type of electronic product and its application. Here are some common SIC codes related to electronic products:

1. SIC 3661 - Telephone and Telegraph Apparatus: This includes companies involved in the manufacturing of telephone and telegraph equipment, including electronic components and systems.

2. SIC 3674 - Semiconductors and Related Devices: This code covers businesses that manufacture semiconductors and related devices, which are fundamental components in a wide range of electronic products.

3. SIC 3695 - Magnetic and Optical Recording Media: This includes companies that produce magnetic and optical recording media, such as hard drives, CDs, DVDs, and other storage devices.

4. SIC 3812 - Search, Detection, Navigation, Guidance, Aeronautical, and Nautical Systems and Instruments: This code is for companies that manufacture electronic systems and instruments used for navigation, guidance, and detection.

5. SIC 3825 - Instruments for Measuring and Testing of Electricity and Electrical Signals: This includes companies that produce electronic instruments and equipment for measuring and testing electrical signals.

6. SIC 3845 - Electromedical and Electrotherapeutic Apparatus: This code covers companies that manufacture electronic medical devices and therapeutic equipment.

7. SIC 5065 - Electronic Parts and Equipment, Not Elsewhere Classified: This includes businesses involved in the wholesale distribution of electronic parts and equipment that do not fall under other specific SIC codes.

8. SIC 5731 - Radio, Television, and Consumer Electronics Stores: This code is for retail stores that sell electronic products such as radios, televisions, and other consumer electronics.

9. SIC 7372 - Prepackaged Software: While not directly an electronic product, this code is relevant for companies that develop software for electronic devices.

10. SIC 7373 - Computer Integrated Systems Design: This includes companies that design and integrate computer systems, which often involve various electronic components.

These SIC codes help in categorizing businesses for statistical, regulatory, and business purposes. When looking for a specific SIC code for an electronic product, it's important to consider the primary function and application of the product to determine the most appropriate code.
