Here's a source. $55 billion, of which $7b is flowers, and the rest of the majority is trans-shipments, according to the USDA. "World exports in agricultural products totals $622 billion. The field is dominated by the USA, the Netherlands and France, with exports worth $68, $55 and $46 billion, respectively. Belgium and Luxembourg, export a combined $27 billion of agricultural products. More than thirteen percent of global agriculture and food export moves through the Benelux’s two main ports, Rotterdam and Antwerp, which serve most of Northern and Central Europe. The value of world export in horticultural products (plants and flowers, vegetables and fruit) is $71 billion. The Benelux share of this market is substantial, roughly 26%, or $19 billion. The Netherlands is a large producer and exporter of vegetables and the world’s largest exporter of ornamental plant products, in addition to being a major trans-shipment station for fruit. Meanwhile, Belgium has a considerable market share in world export of vegetables and fruit, but in reality the majority of the trade in fruit is trans-shipments. World export in plants (live trees and other plants; bulbs; cut flowers and ornamental foliage) was $12.4 billion in 2003. Over sixty percent, or $7.6 billion worth, was exported via the Netherlands, and the vast majority ($6.3 billion worth) were Dutch-produced." "Netherlands: Agricultural situation".
