The Medical Equipment Donation Agency connects you with interested charities to get your medical supplies, equipment or machinery into the hands of those who can use it, promoting waste-stream reduction, cost-effectiveness and global medical aid. Join the Med-EQ network, post your items and the charity in need will provide for pickup and give you a tax deduction receipt.

MEDSHARE INTERNATIONAL
MedShare collects surplus medical supplies and used biomedical equipment from U. S. hospitals and manufacturers. They process the donated material and make them available to hospitals and clinics overseas in two ways: 1) direct shipments to international applicant institutions and 2) supplying medical mission teams.
