Sierra Leone Customs Status & U.S. Trade Treatment
Tariff treatment, trade-agreement coverage, and live monthly U.S. import/export data for Sierra Leone.
As of April 2026, the United States imported $1.6M/month and exported $7.8M/month with Sierra Leone. This page covers Sierra Leone's customs status, applicable trade agreements, and the practical tariff treatment U.S. importers and exporters should expect.
Trade overview
Sierra Leone's US export basket is led by minerals — particularly rutile (titanium ore), diamonds, and iron ore — reflecting the country's resource-rich geology along the West African coast. Diamond imports are subject to the Kimberley Process Certification Scheme, which requires a government-issued certificate of origin to confirm that stones are conflict-free before US Customs and Border Protection will admit them. Rutile, a key feedstock for titanium dioxide pigment production, positions Sierra Leone as a niche but important supplier to the US chemicals and coatings industries.
