Why did the British East India Company have so much unsold tea?

Colonists were buying smuggled tea, for cheaper prices then the BEI Co, so they in-turn sold dirt cheap tea to England, that was of better quality then the smugglers. So you would think the colonists would go for it, but England also needed taxes to pay for the costs from the French and Indian War. So they put a tax on the BEI Co's tea, which in turn, made the colonists flip out. For no apperent reason. lolWhy did the British East India Company have so much unsold tea?
Ark is more or less right, but I thought the problems started when the BEI company pointed out that it could not compete with smuggled tea and got the tax lifted. That threatened to put the smugglers out of business, so they organised a raid on the BEIC tea in Boston.Why did the British East India Company have so much unsold tea?
