Manny Pacquiao Foundation Sued -- Used Clothes Are NOT 'Relief Goods'

The Manny Pacquaio Foundation is learning the hard way ... used clothes do NOT count as "relief goods" in the Philippines ... this according to a lawsuit obtained by TMZ.

Manny's charity is being sued by a logistics company which claims they were hired by the MPF to ship several containers filled with "relief goods" to Manny's home country back in 2009.

But according to the lawsuit, "The containers were inspected by the Philippines authorities and found to have contained used clothing rather than relief goods and have held such containers as a violation of Philippines law."

The logistics company says the goods never made it to the people in need ... because they were confiscated by Philippine officials.

In the suit, the company implies Manny's Foundation is using the incident as an excuse to dodge the $35,805.36 bill ... even though it clearly believes it was the Foundation's responsibility to correctly label the goods.

The shipping company is now demanding the full payment -- plus interest.
