Driver Monitoring System Parts Classification: CAAR Delhi Rules on CTH 8708 vs CTH 8512 — Mitsubishi Electric India Case

Overview of the Advance Ruling Applications

The Customs Authority for Advance Rulings (CAAR), New Delhi recently adjudicated three consolidated advance ruling applications filed by M/s Mitsubishi Electric India Private Limited, a wholly owned Indian subsidiary of Mitsubishi Electric Corporation, Japan, engaged in manufacturing and trading of automotive and electrical components. The applicant, holding IEC No. 0498049850 and PAN AABCM8474A, operates from Plot No. 167-170, Sector 5, IMT Manesar, Gurugram, Haryana.

All three applications were received by the CAAR Secretariat on 16.02.2026 under Section 28I(1) of the Customs Act, 1962. The core issue across all applications was the determination of the correct tariff classification and duty exemption eligibility for three distinct components constituting a Driver Monitoring System (DMS) imported from Japan — namely, the Cable, the Unit Assembly, and the Controller Assembly.

The applicant proposed:

  • Cable → CTH 8544 42 20
  • Unit Assembly → CTH 8512 90 00
  • Controller Assembly → CTH 8512 90 00

The Port Commissionerate, upon examining technical literature, initially concurred with all three proposed classifications. However, CAAR Delhi, after an independent analysis, arrived at a partially divergent conclusion.

What Is a Driver Monitoring System (DMS)?

Before embarking on the classification exercise, CAAR undertook a thorough examination of the DMS as a functional whole.

A DMS is an in-cabin vehicular safety arrangement that continuously monitors the driver's facial condition — including attentiveness, drowsiness, distraction, impairment, and unresponsiveness — and initiates appropriate warning responses either through audible alerts or visual messages on the vehicle's information display panel. The system is designed to enhance the safety of the driver, co-passengers, and the vehicle at large.

Structural Composition of DMS

The DMS operates through three interconnected sub-components, each performing a distinct but interdependent function:

Component Function
Unit Assembly Captures the driver's visual/facial data through an embedded camera and LED
Cable Transmits power and data signals between the Unit Assembly and Controller Assembly
Controller Assembly Analyses and processes the received image data and forwards processed output to the vehicle's BCM

The Body Control Module (BCM) — an external vehicle system — is the component that ultimately commands the buzzer or indicator lamp to generate the actual driver alert. Critically, none of the three DMS components independently performs any signalling function.

Application No. 01 — Classification of Cable

Nature of the Goods

The Cable is a PVC-insulated electric conductor equipped with connectors on both ends. It serves as the physical link between the Unit Assembly and the Controller Assembly within the DMS, facilitating transmission of electrical signals and power between the two.

Applicant's Position

The assessee contended that the Cable is squarely covered under CTH 8544 42 20 as a plastic-insulated electric conductor fitted with connectors, designed for a voltage not exceeding 1,000 volts. The relevant tariff structure is as follows:

CTH 8544 42 20 — Insulated electric conductors fitted with connectors — Plastic Insulated — For a voltage not exceeding 1,000V

The assessee further argued that Section Note 2(a) of Section XVI mandates that goods specifically covered under Chapter 84 or Chapter 85 headings must be classified in those respective headings, regardless of end-use application. Since Heading 8544 expressly covers insulated wires and cables fitted with connectors, the Cable must remain classified there.

Additionally, given the import origin from Japan, the assessee claimed exemption under Serial No. 733 of Notification No. 69/2011-Customs dated 29.07.2011, which covers all goods falling under sub-headings 8544 20 to 8544 60.

CAAR's Ruling on Cable

CAAR agreed with the applicant's position on Cable classification. The Authority held that:

  • The Cable is a PVC-insulated electric conductor with connectors at both ends
  • Heading 8544 specifically and expressly covers such goods
  • Section Note 2(a) of Section XVI mandates classification under the specific heading irrespective of end use
  • CTH 8544 42 20 is the correct classification for the Cable

Ruling: Cable is classifiable under CTH 8544 42 20 and is eligible for customs duty exemption under Serial No. 733 of Notification No. 69/2011-Customs dated 29.07.2011.

Application No. 02 — Classification of Unit Assembly

Nature of the Goods

The Unit Assembly is mounted inside the vehicle cabin and consists of the following sub-elements:
