Customs exemption for optical network equipment denied where switching and protection devices fell within the notification's exclusion clause.

Optical switch and line protection equipment imported under CTH 85176290 was analysed against Notification No. 02/2019-Cus, which grants concessional BCD but excludes optical transport equipment, combinations of packet optical transport products or switches, and optical transport network products. The 2023 circular was read with the notification to clarify that the exclusion covered OTN equipment, DWDM, CWDM and related elements, including optical line protection equipment. Technical material showing the goods as part of a data transmission and network protection system with fault-triggered switching supported classification within the excluded class, so the concessional duty benefit was denied.

Issues: Whether Optical Switch Unit / Optical Line Protection equipment imported under CTH 85176290 was entitled to concessional BCD at 10% under Notification No. 02/2019-Cus, or whether it fell within the exclusion entries covering optical transport equipment and optical transport network products.

Analysis: The exemption notification granted 10% BCD to goods under CTH 8517 62 90 and 8517 69 90, but excluded optical transport equipment, combinations of packet optical transport products or switches, and optical transport network products. The Board circular issued in 2023 clarified that the excluded category covered OTN equipment, DWDM, CWDM, and their elements, including optical line protection equipment. On the facts, the imported equipment was treated as an essential part of the data transmission and network protection system, with switching functions used for immediate connectivity upon fault detection. The technical material on record, including the generic requirements for optical transport network systems, supported the view that optical switching and protection devices were within the excluded class, and the circular was read harmoniously with the notification to identify the covered equipment.

Conclusion: The imported goods were held to fall within the exclusion clause and were not eligible for concessional BCD at 10%.

Final Conclusion: The appeal failed because the imported optical switch and line protection equipment was treated as excluded from the benefit of the concessional customs notification.

Ratio Decidendi: Where a customs exemption notification expressly excludes optical transport and optical network equipment, contemporaneous circular guidance and technical specifications may be used to identify the covered equipment and deny the exemption to goods falling within the excluded class.
