What was the purpose of the Tea Act?

The purpose of the Tea Act of May 10, 1773 was to rescue the financially desperate British East India Company by giving it a near monopoly on tea sales in the American colonies and to vindicate Parliament's authority to tax the colonies through the preserved three pence per pound Townshend duty payable in colonial ports. The East India Company had been the most powerful trading enterprise in the world, controlling Britain's commerce with India, but by 1772 it was on the brink of insolvency. It had borrowed heavily, suffered military costs of governing Bengal after 1757, and lost markets when famine hit India in 1770 to 1771. The Company had about 17 million pounds of unsold tea sitting in London warehouses and was about to default on its loans to the Bank of England.

A collapse threatened British public finances directly because the Company paid huge dividends to the government and to British shareholders, and indirectly because the Company's lands and trade in India underwrote British imperial power. Lord North's ministry searched for a way to dispose of the surplus tea profitably. The Tea Act allowed the Company to ship tea directly to American consignees without paying the full British import duty and without auctioning to British wholesalers, dropping the price of legal tea below the smuggled Dutch tea that perhaps three quarters of American tea drinkers consumed.

North reasoned that colonial consumers would prefer cheap legal tea, that Company finances would recover, that British tax revenue would rise from the surviving Townshend duty paid in America, and that the symbolic principle of parliamentary taxation would be reinforced because the colonies would have effectively accepted a tax. The Act therefore had three purposes layered together: corporate rescue, fiscal revenue, and constitutional assertion. The constitutional purpose was perhaps the most provocative.

Lord North could have repealed the Townshend duty on tea entirely, eliminated the colonial objection, and still rescued the Company through cheaper tea. He chose to keep the duty as a marker of Parliament's right to tax the colonies. Colonial leaders read the choice exactly as North intended and refused to be quietly co-opted. Sons of Liberty leaders Samuel Adams and others recognized that low priced legal tea would drown colonial protest in cheap consumption, and they organized to prevent the tea from being landed. Mass meetings in major colonial ports demanded that consignees resign and ships return to England, and when Governor Hutchinson refused to clear the Boston ships, the Boston Tea Party of December 16, 1773 destroyed 342 chests of Company tea. Britain's heavy handed response in the Coercive Acts of 1774 confirmed that the constitutional dispute could no longer be papered over.
