Inland Customs Line

Inland Customs Line is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Inland Customs Line rather than just read about it. In short: The Inland Customs Line, incorporating the Great Hedge of India (or Indian Salt Hedge), was a customs barrier built by the British colonial rulers of India to prevent smuggling of salt from coastal regions in order to avoid the substantial salt tax. The customs line was begun under the East India Company and continued into direct British rule.

Reference excerpt

The Inland Customs Line, incorporating the Great Hedge of India (or Indian Salt Hedge), was a customs barrier built by the British colonial rulers of India to prevent smuggling of salt from coastal regions in order to avoid the substantial salt tax. The customs line was begun under the East India Company and continued into direct British rule. The line had its beginnings in a series of customs houses established in Bengal in 1803 to prevent the smuggling of salt to avoid the tax. These customs houses were eventually formed into a continuous barrier that was brought under the control of the Inland Customs Department in 1843. The line was gradually expanded as more territory was brought under British control until it covered more than 2,500 miles (4,000 km), often running alongside rivers and other natural barriers. It ran from the Punjab in the northwest to the princely states of Orissa, near the Bay of Bengal, in the southeast. The line was initially made of dead, thorny material such as the Indian plum but eventually evolved into a living hedge that grew up to 12 feet (3.7 m) high and was compared to the Great Wall of China. The Inland Customs Department employed customs officers, jemadars and men to patrol the line and apprehend smugglers, reaching a peak of more than 14,000 staff in 1872. The line and hedge were abandoned in 1879 when the British seized control of the Sambhar Salt Lake in Rajasthan and applied tax at the point of manufacture. The salt tax itself remained in place until 1946.

Origins When the Inland Customs Line was first conceived, British India was governed by the East India Company. This situation lasted until 1858 when the responsibility for government of the colony was transferred to the Crown following the events of the Indian Rebellion of 1857. By 1780 Warren Hastings, the company's Governor-General of India, had brought all salt manufacture in the Bengal Presidency under company control. This allowed him to increase the ancient salt tax in Bengal from 0.3 rupees per maund (37 kg) to 3.25 rupees per maund by 1788, a rate that it remained at until 1879. This brought in 6,257,470 rupees for the 1784–85 financial year, at a cost to an average Indian family of around two rupees per year (two months' income for a labourer). There were taxes on salt in the other British India territories but the tax in Bengal was the highest, with the other taxes at less than a third of the Bengal tax rate.

It was possible to avoid paying the salt tax by extracting salt illegally in salt pans, stealing it from warehouses or smuggling salt from the princely states which remained outside of direct British rule. The latter was the greatest threat to the company's salt revenues. Much of the smuggled salt came into Bengal from the west and the company decided to act to prevent this trade. In 1803 a series of customs houses and barriers were constructed across major roads and rivers in Bengal to collect the tax on traded salt as well as duties on tobacco and other imports. These customs houses were backed up by "preventative customs houses" located near salt works and the coast in Bengal to collect the tax at source. These customs houses alone did little to prevent the mass avoidance of the salt tax. This was due to the lack of a continuous barrier, corruption within the customs staff and the westward expansion of Bengal towards salt-rich states. In 1823 the Commissioner of Customs for Agra, George Saunders, installed a line of customs posts along the Ganges and Yamuna rivers from Mirzapur to Allahabad that would eventually evolve into the Inland Customs Line. The main aim was to prevent salt from being smuggled from the south and west but there was also a secondary line running from Allahabad to Nepal to prevent smuggling from the Northwest frontier. The annexation of Sindh and the Punjab allowed the line to be extended north-west by G. H. Smith, who had become Commissioner of Customs in 1834. Smith exempted items such as tobacco and iron from taxation to concentrate on salt and was responsible for expanding and improving the line, increasing its budget to 790,000 rupees per year and the staff to 6,600 men. Under Smith, the line saw many reforms and was officially named the Inland Customs Line in 1843.

Inland Customs Line Smith's new Inland Customs Line was first concentrated between Agra and Delhi and consisted of a series of customs posts at one mile intervals, linked by a raised path with gateways (known as "chokis") to allow people to cross the line every four miles. Policing of the barrier and surrounding land, to a distance of 10 to 15 miles (16 to 24 km), was the responsibility of the Inland Customs Department, headed by a Commissioner of Inland Customs. The department staffed each post with an Indian Jemadar (approximately equivalent to a British Warrant Officer) and ten men, backed up by patrols operating 2–3 miles behind the line. The line was mainly concerned with the collection of the salt tax but also collected tax on sugar exported from Bengal and functioned as a deterrent against opium, bhang and cannabis smuggling.

The end of company rule in 1858 allowed the British government to expand Bengal through territorial acquisitions, updating the line as needed. In 1869 the government in Calcutta ordered the connection of sections of the line into a continuous customs barrier stretching 2,504 miles (4,030 km) from the Himalayas to Orissa, near the Bay of Bengal. This distance was said to be the equivalent of London to Constantinople. The north section from Tarbela to Multan was lightly guarded with posts spread further apart as the wide Indus River was judged to provide a sufficient barrier to smuggling. The more heavily guarded section was around 1,429 miles (2,300 km) long and began at Multan, running along the rivers Sutlej and Yamuna before terminating south of Burhanpur. The final 794-mile (1,278 km) section reverted to longer distances between customs posts and ran east to Sonapur. In the 1869–70 financial year the line collected 12.5 million rupees in salt tax and 1 million rupees in sugar duties at a cost of 1.62 million rupees in maintenance. In this period the line employed around 12,000 men and maintained 1,727 customs posts. By 1877 the salt tax was worth £6.3 million (approx 29.1 million rupees) to the British government in India, with the majority being collected in the Madras and Bengal provinces, lying on either side of the customs line.

Worked examples

Example 1 — a first encounter with Inland Customs Line

Start with the simplest possible case. Write down what Inland Customs Line claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inland Customs Line before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inland Customs Line ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inland Customs Line

In research
Inland Customs Line appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Inland Customs Line in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Inland Customs Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics Border barriers, Customs duties, Economic history of India, so understanding it makes those chapters shorter.
In everyday life
Look for Inland Customs Line outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
