In the past few months, retail prices of petrol and diesel have consistently increased and have reached all-time high levels. On September 24, 2018, the retail price of petrol in Delhi was Rs 82.72/litre, and that of diesel was Rs 74.02/litre. In Mumbai, these prices were even higher at Rs 90.08/litre and Rs 78.58/litre, respectively.
The difference in retail prices in the two cities is because of the different tax rates levied by the respective state governments on the same products. This blog post explains the major tax components in the price structure of petrol and diesel and how tax rates vary across states. It also analyses the shift in the taxation of these products, its effect on retail prices, and the consequent revenue generated by the central and state governments.
What are the components of the price structure of petrol and diesel?
Retail prices of petrol and diesel in India are revised by oil companies on a daily basis, according to changes in the price of global crude oil. However, the price paid by oil companies makes up 51% of the retail price in case of petrol, and 61% in the case of diesel (Table 1). The break-up of retail prices of petrol and diesel in Delhi, as on September 24, 2018, shows that over 45% of the retail price of petrol comprises central and states taxes. In the case of diesel, this is close to 36%.
At present, the central government has the power to tax the production of petroleum products, while states have the power to tax their sale. The central government levies an excise duty of Rs 19.5/litre on petrol and Rs 15.3/litre on diesel. These make up 24% and 21% of the retail prices of petrol and diesel, respectively.
While excise duty rates are uniform across the country, states levy sales tax/value added tax (VAT), the rates of which differ across states. The figure below shows the different tax rates levied by states on petrol and diesel, which results in their varying retail prices across the country. For instance, the tax rates levied by states on petrol ranges from 17% in Goa to 39% in Maharashtra.
Note that unlike excise duty, sales tax is an ad valorem tax, i.e., it does not have a fixed value, and is charged as a percentage of the price of the product. This implies that while the excise duty component of the price structure is fixed, the sales tax component is charged as a proportion of the price paid by oil companies, which in turn depends on the global crude oil price. With the recent increase in the global prices, and subsequently the retail prices, some states such as Rajasthan, Andhra Pradesh, West Bengal, and Karnataka have announced tax rate cuts.
How have retail prices in India changed vis-à-vis the global crude oil price?
India’s dependence on imports for consumption of petroleum products has increased over the years. For instance, in 1998-99, net imports were 69% of the total consumption, which increased to 93% in 2017-18. Because of a large share of imports in the domestic consumption, any change in the global price of crude oil has a significant impact on the domestic prices of petroleum products. The following figures show the trend in price of global crude oil and retail price of petrol and diesel in India, over the last six years.
The global price of crude oil (Indian basket) decreased from USD 112/barrel in September 2012 to USD 28/barrel in January 2016. Though the global price dropped by 75% during this period, retail prices of petrol and diesel in India decreased only by 13% and 5%, respectively. This disparity in decrease of global and Indian retail prices was because of increase in taxes levied on petrol and diesel, which nullified the benefit of the sharp decline in the global price. Between October 2014and June 2016, the excise duty on petrol increased from Rs 11.02/litre to Rs 21.48/litre. In the same period, the excise duty on diesel increased from Rs 5.11/litre to Rs 17.33/litre.
Over the years, the central government has used taxes to prevent sharp fluctuations in the retail price of diesel and petrol. For instance, in the past, when global crude oil price has increased, duties have been cut. Since January 2016, the global crude oil price has increased by 158% from USD 28/barrel to USD 73/barrel in August 2018. However, during this period, excise duty has been reduced only once by Rs 2/litre in October 2017. While the central government has not signalled any excise duty cut so far, it remains to be seen if any rate cut will happen in case the global crude oil price rises further. With US economic sanctions on Iran coming into effect on November 4, 2018, India may face a shortfall in supply since Iran is India’s third largest oil supplier. Moreover, Organization of Petroleum Exporting Countries (OPEC) and Russia have not indicated any increase in supply from their side yet to offset the possible effect of sanctions. As a result, in a scenario with no tax rate cut, this could increase the retail prices of petrol and diesel even further.
How has the revenue generated from taxing petroleum products changed over the years?
As a result of successive increases in excise duty between November 2014 and January 2016, the year-on-year growth rate of excise duty collections increased from 27% in 2014-15 to 80% in 2015-16. In comparison, the growth rate of sales tax collections was 6% in 2014-15 and 4% in 2015-16. The figure below shows the tax collections from the levy of excise duty and sales tax on petroleum products. From 2011-12 to 2017-18, excise duty and sales tax collections grew annually at a rate of 22% and 11%, respectively.
How is this revenue shared between centre and states?
Though central taxes are levied by the centre, it gets only 58% of the revenue from the levy of these taxes. The rest 42% is devolved to the states as per the recommendations of the 14th Finance Commission. However, excise duty levied on petrol and diesel consists of two broad components – (i) excise duty component, and (ii) road and infrastructure cess. Of this, only the revenue generated from the excise duty component is devolved to states. Revenue generated by the centre from any cess is not devolved to states.
The cess component was increased by Rs 2/litre to Rs 8/litre in the Union Budget 2018-19. However, this was done by reducing the excise duty component by the same amount, so as to keep the overall rate the same. Essentially this provision shifted the revenue of Rs 2/litre of petrol and diesel from states’ divisible pool of taxes to the cess revenue, which is entirely with the centre. This cess revenue is earmarked for financing infrastructure projects.
At present, of the Rs 19.5/litre excise duty levied on petrol, Rs 11.5/litre is the duty component, and Rs 8/litre is the cess component. Therefore, accounting for 42% share of states in the duty component, centre effectively gets a revenue of Rs 14.7/litre, while states get Rs 4.8/litre. Similarly, excise duty of Rs 15.3/litre levied on diesel consists of a cess component of Rs 8/litre. Thus, excise duty on diesel effectively generates revenue of Rs 12.2/litre for the centre and Rs 3.1/litre for states.
Recently, there have been reports of price crashes and distress sales in case of farm produce, such as tomatoes, mangoes, and garlic. In some cases, farmers have dumped their produce on roads. Produce such as fruits and vegetables are perishable and therefore have a short shelf life. Further, due to inadequate storage facilities and poor food processing infrastructure farmers have limited options but to sell the produce at prevailing market prices. This can lead to distress sales or roadside discards (in some cases to avoid additional cost of transportation).
Food processing allows raw food to be stored, marketed, or preserved for consumption later. For instance, raw agricultural produce such as fruits may be processed into juices, jams, and pickles. Activities such as waxing (for preservation), packaging, labelling, or ripening of produce also form part of the food processing industry.
Between 2001-02 and 2016-17, production of food grains grew annually at 1.7% on average. Production of horticulture crops surpassed food grains with an average growth rate of 4.8%. While production has been increasing over the years, surplus produce tends to go waste at various stages such as procurement, storage, and processing due to lack of infrastructure such as cold storages and food processing units.

Losses high among perishables such as fruits and vegetables
Crop losses ranged between 7-16% among fruits and around 5% among cereals in 2015. The highest losses were witnessed in case of guava, followed by mango, which are perishable fruits. Perishables such as fruits and vegetables are more prone to losses as compared to cereals. Such crop losses can occur during operations such as harvesting, thrashing, grading, drying, packaging, transportation, and storage depending upon the commodity.
It was estimated that the annual value of harvest and post-harvest losses of major agricultural products at the national level was Rs 92,651 crore in 2015. The Standing Committee on Agriculture (2017) stated that such wastage can be reduced with adequate food processing facilities.

Inadequate food processing infrastructure
As previously discussed, perishables such as fruits and vegetables are more prone to damages as compared to cereals. Due to inadequate processing facilities in close proximity, farmers may be unable to hold their produce for a long time. Hence, they may be forced to sell their produce soon after harvest, irrespective of the prevailing market situations. Expert committees have recommended that agri-logistics such as cold chain infrastructure and market linkages should be strengthened.
Cold chain infrastructure: Cold chain infrastructure includes processing units, cold storages, and refrigerated vans. As of 2014, out of a required cold storage capacity of 35 million metric tonnes (MT), almost 90% (31.8 million MT) of the capacity was available (see Table 1). However, cold storage needs to be coupled with logistical support to facilitate smooth transfer of harvested value from farms to distant locations. This includes: (i) pack-houses for packaging and preparing fresh produce for long distance transport, (ii) refrigerated transport such as reefer vehicles, and (iii) ripening chambers to ripen raw produce before marketing. For instance, bananas which are harvested raw may be ripened in these chambers before being marketed.
While there are sufficient cold storages, there are wide gaps in the availability of other associated infrastructure. This implies that even though almost 90% (32 million tonnes) of cold storage capacity is available, only 15% of the required refrigerated transport exists. Further, the shortfall in the availability of infrastructure necessary for safe handling of farm produce, like pack-houses and ripening chambers, is over 90%.

To minimise post-harvest losses, the Standing Committee (2017) recommended that a country-wide integrated cold chain infrastructure network at block and district levels should be created. It further recommended that a Cold Chain Coordination and Monitoring Committee should be constituted at the district-level. The Standing Committee also recommended that farmers need to be trained in value addition activities such as sorting, grading, and pre-cooling harvested produce through facilities such as freezers and ripening chambers.
Between 2008 and 2017, 238 cold chain projects were sanctioned under the Scheme for Integrated Cold Chain and Value Addition Infrastructure. Grants worth Rs 1,775 crore were approved for these projects. Of this amount, Rs 964 crore (54%) has been released as of January 2018. Consequently, out of the total projects sanctioned, 114 (48%) are completed. The remaining 124 projects are currently under implementation.
Transport Facilities: Currently, majority of food grains and certain quantities of tea, potato, and onion are transported through railways. The Committee on Doubling Farmers Income had recommended that railways needs to upgrade its logistics to facilitate the transport of fresh produce directly to export hubs. This includes creation of adjoining facilities for loading and unloading, and distribution to road transport.
Mega Food Parks: The Mega Food Parks scheme was launched in 2008. It seeks to facilitate setting up of food processing units. These units are to be located at a central processing centre with infrastructure required for processing, packaging, quality control labs, and trade facilitation centres.
As of March 2018, out of the 42 projects approved, 10 were operational. The Standing Committee on Agriculture noted certain reasons for delay in implementation of projects under the scheme. These include: (i) difficulty in getting loans from banks for the project, (ii) delay in obtaining clearances from the state governments and agencies for roads, power, and water at the project site, (iii) lack of special incentives for setting up food processing units in Mega Food Parks, and (iv) unwillingness of the co-promoters in contributing their share of equity.
Further, the Standing Committee stated that as the scheme requires a minimum area of 50 acres, it does not to promote smaller or individual food processing and preservation units. It recommended that smaller agro-processing clusters near production areas must be promoted. The Committee on Doubling Farmers Income recommended establishment of processing and value addition units at strategic places. This includes rural or production areas for pulses, millets, fruits, vegetables, dairy, fisheries, and poultry in public private-partnership mode.
