The Parliamentary Standing Committee on Health and Family Welfare tabled a Report in Parliament on May 8, 2012, on the functioning of the Central Drugs Standard Control Organization (CDSCO).  CDSCO is the agency mandated with the regulation of drugs and cosmetics in India.  The Report covers various aspects of drug regulation including organizational structure and strength of CDSCO, approval of new drugs, and banning of drugs, among others. Following the Report, the Minister of Health and Family Welfare has constituted a Committee to look into the procedure for drug regulation.  The Committee is expected to make its submissions within a period of two months. This post focuses on irregularities in the approval of new drugs by CDSCO.  It discusses the regulations relating to drug approval and the Standing Committee's observations on the working of CDSCO. Approval of new drugs Drugs are regulated by the Drugs and Cosmetics Act, 1940 and Drugs and Cosmetic Rules, 1945 [Rules].  The CDSCO, under the Ministry of Health and Family Welfare, is the authority that approves new drugs for manufacture and import.  State Drug Authorities are the licensing authorities for marketing drugs. New Drugs are defined as:

  • drugs that have not been used in the country before,
  • drugs that have been approved by a Licensing Authority but are now being marketed for different purposes, and
  • fixed dose combinations of two or more drugs that have been individually approved before but are proposed to be combined in a fixed ratio that has not been approved.

The Rules require an applicant for a new drug to conduct clinical trials in India to determine the drug’s safety and efficacy.  These trials are necessary for both domestically manufactured and imported drugs.  However, the authority can exempt a drug from the requirement of local and clinical trials in the public interest based on data available in other countries. Observations and recommendations of the Committee The Committee found that a total of 31 new drugs were approved between January 2008 and October 2010 without conducting clinical trials on Indian patients.  The Report mentioned that drug manufacturers, CDSCO officials and medical experts colluded to approve drugs in violation of laws.  Following are some of the Report’s findings:

  • Under the Rules, the Drugs Controller General (India) (DCGI), the head of CDSCO, can clear sites of clinical trials after ensuring that major ethnic groups are enrolled in these trials to have a truly representative sample.  This rule was violated by the DCGI when sites for clinical trials were approved without ensuring diversity.  The Committee recommended that the DCGI approve sites for trials only if they cover patients from major ethnic backgrounds.
  •  The Report found that certain actions by experts were in violation of the Code of Ethics of the Medical Council of India.  A review of expert opinions revealed that several medical expert recommendations had been given as personal opinions rather than on the basis of scientific data.  Additionally, many expert opinions were written by what the Report calls ‘the invisible hands’ of drug manufacturers.  The Committee recommended that CDSCO formulate a clear set of written guidelines on the selection process of experts with emphasis on expertise in the area of drugs.
  •  The Rules ban the import and marketing of any drug whose use is prohibited in the country of origin.  CDSCO violated this rule by approving certain Fixed Dose Combination drugs for clinical trials without considering the drugs’ regulatory status in their respective country of origin.  Drugs such as Deanxit and Buclizine, which have been prohibited for sale and use in their countries of origin, Denmark and Belgium, respectively, were approved for clinical trials.  The Committee recommended an inquiry into the unlawful approval of these drugs.
  • The Rules require animal studies to be conducted for approval of a drug for use by women of reproductive age.  CDSCO violated this rule in approving Letrozole for treating female infertility.  Globally the drug has only been used as an anti-cancer drug for use among post-menopausal women.  The drug has not been permitted for use among women of reproductive age because of side effects.  The Committee recommended that responsibility be fixed for unlawfully approving Letrozole.
  •  Rules require Post-marketing Safety Update Reports (PSURs) on drugs to be submitted to CDSCO.  PSURs are used to collect information on adverse effects of drugs on Indian patients as a result of ethnic differences.  When asked by the Committee to furnish PSURs on 42 randomly selected new drugs, the Ministry was able to submit PSURs for only 8 drugs.  The Report contended that this action reflected a poor follow-up of side effects on Indian patients.  The Committee recommended that manufacturers of new drugs be warned about suspension of marketing approval unless they comply with mandatory rules on PSURs.

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.

Table 1

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.

Effective Sales Tax

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.

Petrol

Diesel

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.

Tax revenue

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.
