European Union statistics office Eurostat said on Tuesday that the trade surplus of the 19-nation euro zone was €19.0 billion (£16.89 billion) on a non-seasonally adjusted basis, down from €23.4 billion in November 2017, according to Reuters.
Imports were up 4.7 percent, while exports rose a more modest 1.9 percent.
The trade balance was also down by a similar percentage for the 11 months to November.
Eurostat does not provide a breakdown of figures for the euro zone, but for the EU as a whole, energy imports were 25 percent higher in Jan-Nov 2018 than a year earlier. Exports of energy rose by 17 percent. For other product types, there was no major mismatch between the growth rates of exports and of imports.
Over the same 11 month period, the EU's trade surplus with the US and its deficit with China both grew. The EU's trade deficits with its main energy suppliers Russia and Norway also increased.
On a seasonally adjusted basis, the euro zone's trade surplus actually increased to €15.1 billion from €13.5 billion in October. Exports decreased by 1.0 percent, while imports fell by 1.9 percent.
