Data released by the Federal Statistical Agency (Distatis) showed that Germany exported goods worth 129 billion euros in March, down 5.2% from February.
This decline comes after two consecutive months of growth.
Imports also fell in March by 6.4% to 113 billion euros, which led to a trade surplus of 16.7 billion euros on a monthly basis.
Demand for German goods fell across all sectors, with exports to the European Union down 6.2%.
More worryingly, exports to the United States, a major market for Europe, fell by 10.9%.
Overall, the proportion of German exports to countries outside the European Union fell by 4%.
Last Friday, Germany released official data showing steady growth in the first quarter of the year, despite expectations of a slight recovery.
Analysts had warned that a slowdown in the United States could hurt Europe’s biggest economy.
