Issue (i): Whether the Espressif ESP32-C3-DevKitM-I-N4X Development Board is classifiable under tariff heading 8471 as an automatic data processing machine or unit thereof, or under tariff heading 8517 as other apparatus for the transmission or reception of data in a wireless network.
Analysis: Classification was determined on the basis of the General Rules for Interpretation, Chapter Notes to Chapter 84, and the HSN guidance. The development board was found to be a programmable embedded platform, but its essential character was derived from its integrated Wi-Fi and Bluetooth communication capability rather than from general-purpose data processing. It was held not to satisfy the requirements of an automatic data processing machine or a unit thereof, and not to fall within heading 8471.
Conclusion: The board was held classifiable under tariff heading 8517, more specifically under sub-heading 8517 62 90.
Issue (ii): Whether the Espressif ESP32-C3-WROOM-02-N4 Module is classifiable under tariff heading 8473 as a part or accessory of an automatic data processing machine, or under tariff heading 8517 as other apparatus for the transmission or reception of data in a wireless network.
Analysis: The module was found to be an independent wireless communication module with integrated processing and transceiver functions. It was not held to be a part solely or principally used with machines of heading 8471, and heading 8473 was therefore found inapplicable. Its principal function was identified as wireless transmission and reception of data.
Conclusion: The module was held classifiable under tariff heading 8517, more specifically under sub-heading 8517 62 90.
Final Conclusion: The requested classifications under headings 8471 and 8473 were not accepted, and both products were held to fall under heading 8517 as other wireless communication apparatus.
Wireless communication modules and development boards were classified under heading 8517, not as data-processing machines or parts thereof.
Classification of an embedded development board and wireless module was determined under the General Rules for Interpretation, Chapter Notes and HSN guidance by reference to their essential character and principal function. The ESP32-C3-DevKitM-I-N4X development board was treated as a programmable embedded platform whose dominant feature was integrated Wi Fi and Bluetooth communication, so it was not classified as an automatic data processing machine or unit under heading 8471 and was placed under heading 8517. The ESP32-C3-WROOM-02-N4 module was likewise found to be an independent wireless communication module with integrated processing and transceiver functions, not a part or accessory under heading 8473, and was also classified under heading 8517.
Classification of "Espressif ESP32-C3 DevKitM-I-N4X Development Board (Microcontroller Development Board)" and "SOC Product -Espressif ESP32-C3-WROOM-02-N4 Module" - Principal function test for composite electronic goods - Exclusion from automatic data processing machine classification - Wireless Communication Apparatus - Essential Character - General Rules for Interpretation -Whether the Microcontroller Development Board proposed to be imported will be classified under the CTI 84719000, and the SOC Product Module proposed to be imported will be classified under the CTI 84733010 ? Classification of microcontroller development board with integrated Wi-Fi and Bluetooth - classifiable under tariff heading 8471 as an automatic data processing machine or unit thereof, or under tariff heading 8517 as other apparatus for the transmission or reception of data in a wireless network - HELD THAT: - The ESP32-C3-DevKitM-1-N4X is a development board, consisting of a microcontroller (CPU and memory), printed Circuit Board with mounted components and interfaces and communication capability. As per Chapter Note 6 (A) to Chapter 84, an ADP machine must Store processing programs, be freely programmable, perform arithmetic computations and execute processing logic automatically. The applicant contends that the development board contains CPU. memory, processes data from sensors and executes instructions. Therefore, qualifies as an ADP system/unit. The ESP32-C3-DevKitM-1-N4X is a standalone embedded system, not a peripheral unit, does not function as part of a conventional ADP system and does not require Monitor, Keyboard, storage system and operates as a controller, not as a computing system. It is designed to control machines, interface with sensors and execute embedded logic. In the case of Insulation Electrical Private Limited [2008 (3) TMI 22 - SUPREME COURT], the Hon'ble Supreme Court held that a 'part' is an essential component of the whole without which the whole cannot function. This position has been consistently followed and reiterated in a catena of decisions including the decision of the Hon'ble Supreme Court in the case of Prasoon Enterprises [2019 (3) TMI 1361 - SUPREME COURT], wherein it was held that the test for a product to be a part of the other is to see if the other is incomplete without the product or if the other cannot function without it. The complexity or lack of complexity will not be a detriment to the question of identifiable nature of the part. The Authority held that classification had first to be tested under the tariff headings read with the relevant Section and Chapter Notes. Though the development board contains a microcontroller, memory and programmable interfaces, it was found not to answer the description of an automatic data processing machine or unit thereof under Chapter 84, since it functions as an embedded programmable controller for control and communication applications and is not solely or principally used as part of an ADP system. The Authority further held that heading 8542 was inapplicable because the goods were not bare semiconductor devices but assembled electronic modules or boards with multiple mounted components on a printed circuit board. Examining the technical literature and functional architecture, the Authority found that the integrated Wi-Fi and Bluetooth transceiver capability gave the goods their essential character, the embedded processing function being ancillary to wireless communication. Applying the principal function and essential character test, the board was held to fall under heading 8517 as apparatus for transmission or reception of data in a wireless network. [Paras 18, 20, 21, 23] The development board was held classifiable under CTI 8517 62 90 and not under CTI 84719000, 8473 or 8542. Classification of Wi-Fi and Bluetooth module - SOC Product - Espressif ESP32-C3-WROOM-02-N4 Module is classifiable as wireless communication apparatus or as a microprocessor part of automatic data processing machines. - HELD THAT: - The Authority held that heading 8473 applies only to parts and accessories solely or principally used with machines of heading 8471 and lacking an independent function. The subject module was found to be an independent embedded module capable of processing, transmitting and receiving data, with built-in Wi-Fi and Bluetooth, and therefore not a part suitable solely or principally for use with ADP machines. The claim under heading 8542 was also rejected on the ground that the goods were not bare integrated circuits but assembled modules with multiple components mounted on a printed circuit board, a category excluded by the explanatory notes to that heading. Applying Section Note 3 to Section XVI and the functional analysis of the goods, the Authority found that the principal function of the module was wireless data transmission and reception, and that it answered the description of communication apparatus under heading 8517, falling in the residual sub-classification 8517 62 90. [Paras 19, 22, 23] The module was held classifiable under CTI 8517 62 90 and not under CTI 84733010 or heading 8542. Confidentiality of advance ruling - The applicant's request for protection of commercially confidential information - HELD THAT: - Relying on the applicable regulation governing publication of advance rulings, the Authority accepted the request to protect commercially confidential information and directed that the ruling be kept confidential. [Paras 24] The request for confidentiality was approved. Final Conclusion: The Authority rejected the classifications claimed under headings 8471, 8473 and 8542, and held that both the Espressif ESP32-C3 DevKitM-I-N4X Development Board and the Espressif ESP32-C3-WROOM-02-N4 Module are classifiable under CTI 8517 62 90 as wireless communication apparatus. The request to keep the ruling confidential for protection of commercially confidential information was also allowed.
