The Middle East and North Africa region is one of the fastest growing consumers of tobacco products, especially cigarettes. With a young, fast-growing population, where smoking is culturally acceptable and with low awareness of health implications, tobacco consumption is high. In 2010, the region accounted for a 7.1% market share of global cigarettes volume, the fourth largest globally. Significantly, the smoking of pipe tobacco in the region, popular due to the consumption of shisha, represents roughly 45.5% of global demand. By country, Saudi Arabia has the highest per capita consumption of shisha pipe tobacco in the world while Egypt, which is MENA's largest cigarettes market, consumes most in volume terms. Saudi Arabia, with the largest GCC population, is the largest market for the cigarette industry, closely followed by the UAE. "The Global Tobacco Epidemic 2015" report, states that 6 million people a year die from tobacco-related diseases, with that number estimated to increase to 8 million people by 2030. According to the World Health Organization (WHO) and Tobacco Free Initiative (TFI), a 10% price increase on a pack of cigarettes would be expected to reduce demand for cigarettes by about 4% in high-income countries and by about 5% in low- and middle-income countries, where lower incomes tend to make people more sensitive to price changes. This price increase is interlinked with price and tax measures, as Article 6 of the WHO Framework Convention on Tobacco Control states: ‘Price and tax measures are an effective and important means of reducing tobacco consumption by various segments of the population, in particular young persons.' The GCC countries are considering raising custom duty on tobacco, both to raise revenues and for health objectives of reducing consumption and smoking incidence (as per WHO guidelines). Earlier this month, the GCC endorsed a call by the WHO to raise taxes on tobacco. However, they face a number of constraints in achieving their objectives given their international obligations. International & bilateral trade agreements constrain the GCC countries from raising the common external tariff on cigarettes and other tobacco products thereby restricting the ability of the GCC to raise prices to reduce tobacco consumption and smoking incidence, while increasing government revenue from tobacco taxation. The GCC nations are members of the WTO and have to comply with their treaty commitments and with a maximum import duty, known as the ‘bound' rate. The current 100% import duty across the GCC is set at the bound rate for both Bahrain and Kuwait. Furthermore, free trade agreements signed by Bahrain and Oman separately with the US dictate that the countries remove tariffs on cigarettes (among other products) within a ten-year timeframe (due 2016 and 2019 respectively). Last, but not the least, the GCC Customs Union agreement includes a Common External Customs Tariff (CET) for goods imported from outside the GCC, as well as common customs regulations and procedures, which further constrains tobacco tax policy options. The uniform system of cigarette taxation places the Common External Tariff at 100% of the CIF price (ad valorem) and a minimum specific duty equivalent to SR100 per 1,000 cigarettes, whichever is higher. The minimum specific duty component of taxation is an essential component, given that it enables a secure contribution towards the government revenue base. The minimum specific duty was first introduced by Saudi Arabia in the 1990s and was fully harmonized among GCC member states when Kuwait adopted the current KWD 8 per 1000 cigarettes minimum in 2002. In the years that followed, manufacturers have increased prices of many brands above the levels at which the minimum duty applies, thus increasingly subjecting them to the ad valorem component of the tariff. However, the minimum specific duty was not systematically adjusted for inflation and its real value and incidence has declined. Any increase in specific duty would mean that all cigarettes must pay the minimum amount of tax regardless of their CIF price. By contrast, when the ad valorem duty rises, the price of mid and premium price cigarette brands increase by more than that of low and cheap brands given that the tax charged is a proportion of the CIF price. This provides an incentive to consumers to substitute, trading down to cheaper & lower quality products, which could reduce government revenues under a purely ad valorem tax regime and undermine governments' health objectives. The GCC countries should agree and introduce excise taxes on tobacco consumption as a policy tool to increase tobacco prices for health reasons and to raise revenue. Ideally, the introduction of domestic excise taxes on tobacco should be in the form of a specific nominal excise duty to be introduced in each GCC member state consisting of a fixed amount per 1,000 cigarettes or equivalent units of other tobacco products. The new excise duty would be introduced by the Ministries of Finance, with a revised mandate enabled by the requisite legal & regulatory reforms, which would set up the revenue administration. It is also feasible that the revenue administration be out-sourced to customs, which then becomes Customs & Excise. Additionally, there should be GCC policy harmonization, i.e., introduction of tobacco excise taxes should be applied uniformly (including on domestic production), equally and in synchronized manner in all countries in order to prevent arbitrage opportunities and illicit trade or smuggling. The process of implementation of the new tax structure should also be gradual to avoid encouraging smuggling and illicit trade. This will enable the building of tax capacity in the form of tax revenue authorities to implement the fiscal reform, monitor and collect revenue. The set-up of an excise revenue administration has the added advantage of facilitating the introduction of other excises, notably on gasoline, diesel and other oil products – gradually leading to revenue diversification and eventually fiscal consolidation. * The writer is President of Nasser Saidi & Associates, a niche consultant and advisor to governments, central banks, regulators, multi-national and regional companies.
