Why it matters: India-Bhutan bilateral trade crossed US$1.9 billion in financial year 2024-25 - a growth of over 46% over the previous year. For decades this trade has been centred on Jaigaon in West Bengal (opposite Phuentsholing); in 2021 about 75% of the trade passed through this single point. The conversion of the Jaigaon LCS into an Integrated Check Post (ICP) has been pending for years - so far only DPR preparation and the identification of 122 acres of land have happened; kilometre-long queues are recorded at peak times.
Existing Infrastructure on the Border
- Notification and count context: CSEP's analysis of 8 September 2026 mentions 10 points (West Bengal 6, Assam 4), but the same article also lists five Assam connectivity points after Samrang's addition. According to an accessible copy of Notification No. 43/2026-Customs (N.T.), dated 6 May 2026, Samrang was inserted as item (11) in the Bhutan-frontier table, with the Rangia-Tamulpur-Dimakuchi motorable road specified. Do not treat 10 as a current total. A notified entry, a developed ICP and an operational trade point are different things; this article has not verified a current total of operational ports. CSEP names Darranga, Hatisar, Kamardwisa, Ultapani and Samrang in its Assam discussion.
- Darranga ICP: built on 14.5 acres about 700 metres from the Bhutan border; connected to NH-27 and Bhutan's Motanga customs post - a direct corridor to the Motanga Industrial Estate (Samdrup Jongkhar) in eastern Bhutan.
- Trade diversification: in 2024 Hatisar and Darranga were added to the approved ports for Bhutan's 17,000-tonne areca nut quota (earlier a Jaigaon/Chamurchi monopoly); at the commerce secretary-level meeting in Thimphu, agreement was reached on making Darranga an additional entry point for food imports and deploying phyto-quarantine staff.
- Gelephu Mindfulness City: Bhutan's ambitious project will raise the importance of the southern Bhutan and Assam-border corridor.
Significance from the Examination Point of View
- Prelims: the difference between LCS and ICP (ICP = integrated facility under the Land Ports Authority of India), the locations of Jaigaon-Phuentsholing, Darranga-Samdrup Jongkhar, Samrang (Udalguri), NH-27, India-Bhutan trade figures, the Gelephu project.
- Mains (GS-2/GS-3): border infrastructure and the Neighbourhood First/Act East policy, BBIN connectivity, trade balance with smaller neighbours, the economic development of border areas.
Prelims Practice Questions

(a) Darrang
(b) Udalguri
(c) Kamrup
(d) Bongaigaon
Answer and explanation

Question 2. About how much was India-Bhutan bilateral trade in financial year 2024-25?
(a) $0.9 billion
(b) $1.9 billion
(c) $4.6 billion
(d) $19 billion
Answer and explanation
Answer: (b) - $1.9 billion - a growth of over 46% compared with the previous year. This growth pressure is the main argument for diversifying beyond the single Jaigaon gateway.
Question 3. The Darranga ICP connects directly to which industrial area of Bhutan?
(a) Phuentsholing
(b) Gelephu
(c) Motanga (Samdrup Jongkhar)
(d) Paro
Answer and explanation
Answer: (c) - the Motanga Industrial Estate, Samdrup Jongkhar district - the Darranga ICP is built on NH-27 about 700 metres from the border, reducing the cost of transporting raw material, coal and heavy machinery.
Question 4. What is the main difference between an LCS and an ICP?
(a) No difference
(b) An ICP integrates border facilities (except foreign exchange) in one complex; an LCS is a limited customs facility
(c) An ICP is only for air routes
