BRUSSELS (Reuters) - Anheuser-Busch InBev ABI.BR faces an EU antitrust fine for preventing cheaper beer imports into Belgium despite its efforts to settle the investigation, people familiar with the matter said.

Last year, the European Commission accused the world’s largest brewer of abusing its market dominance in Belgium by impeding cheaper imports into the country of its Jupiler and Leffe brands from neighboring France and the Netherlands.

The European Commission typically frowns on attempts to prevent parallel trade in the 28-country bloc, whereby cheaper products in one country are transported for sale in another, seeing such tactics as an obstacle to the single market.

The Commission said the result was that Belgian consumers were paying more for the two most popular beer brands in Belgium. AB InBev sells Jupiler and Leffe at lower prices in the Netherlands and France because of the greater competition in these two markets.

EU antitrust rules allow companies to settle investigations by offering concessions and regulators to close the case without levying any fine or proving wrongdoing. The Commission normally accepts this option only if it sees it as a quicker way to restore competition to the market.

The Commission, which can fine companies up to 10 percent of their global turnover, declined to comment. The sources say a formal decision will take some time before it is announced. AB InBev did not immediately respond to a request for comment

The EU competition enforcer said AB InBev’s tactics included changing the packaging of both brands in the Netherlands and France to make them harder to sell in Belgium. Dutch retailers were given limited access to key products and promotions to prevent them from importing products into Belgium.
