The amount is said to be the highest collected for December in the past five years.
The revenue is derived from goods imported from overseas.
CEO of the Customs, Mr Kelemete Vahe said December is a busy month with festivities and Tongans bring many goods from abroad.
He said most of the goods are food and mainly red meat.
Mr Vahe expressed gratitude to people for not adding difficulties to the tasks of Customs officers by importing illegal goods.
He said there were no illegal firearms, drugs or other illegal items.
