Antitrust regulations don't make a distinction between consumers and businesses. What matters is how certain market actions interfere with the function or operation of the market. Usually, antitrust actions don't even involve consumer harm--they involve harm to competitors. Consumer products are products consumed by an end user not in the course of their business, simply meaning that the product is not resold or otherwise materially used in the production of the consumer's own products. Thus, for example, your work office is a consumer of staples, but Staples would not be (because they are in the business of (re)selling office supplies, even though they also consume them).
