a monopoly

With his new company and new technology, Dow produced bromine very cheaply, and began selling it in the United States for 36 cents per pound. At the time, the German government supported a bromine cartel, Bromkonvention, which had a near-monopoly on the supply of bromine, which they sold in the US for 49 cents per pound. The Germans had made it clear that they would dump the market with cheap bromine if Dow attempted to sell his product abroad. In 1904 Dow defied the cartel by beginning to export his bromine at its cheaper price to England. A few months later, an angry Bromkonvention representative visited Dow in his office and reminded him to cease exporting his bromine.

Unafraid, Dow continued exporting to England and Japan. The German cartel retaliated by dumping the US market with bromine at 15 cents a pound in an effort to put him out of business. Unable to compete with this predatory pricing in the U.S., Dow instructed his agents to buy up hundreds of thousands of pounds of the German bromine locally at the low price. The Dow company repackaged the bromine and exported it to Europe, selling it even to German companies at 27 cents a pound. The cartel, having expected Dow to go out of business, was unable to comprehend what was driving the enormous demand for bromine in the U.S., and where all the cheap imported bromine dumping their market was coming from. They suspected their own members of violating their price-fixing agreement and selling in Germany below the cartel's fixed cost. The cartel continued to slash prices on their bromine in the U.S., first to 12 cents a pound, and then to 10.5 cents per pound. The cartel finally caught on to Dow's tactic and realized that they could not keep selling below cost, they then increased their prices worldwide.
