CNB, headquartered in Lisse, combines flower-bulb brokerage with specialist auctions. One distinctive format is the “groene veiling”, a sale of a crop still standing in the field. This differs from purchasing finished, graded bulbs from a warehouse. Inspection of a particular crop may take place away from Lisse, so the headquarters address should not be assumed to be the location of the goods.
CNB reported EUR 364 million in brokered trade turnover for 2024/25, an increase of EUR 39 million over the preceding year. These figures cover the trading activity described in the announcement, not only green auctions. They indicate the organisation’s scale in the bulb industry but do not measure bulb numbers or the area of crops sold. Comparisons with other businesses should preserve the distinction between the value of brokered transactions and the broker’s own revenue.
The operator publishes an archive of green-auction catalogues and results. An example from 2026 uses “R.R. (afgerond)” and records the outcome of individual entries. This is not a standard price per bulb. Before making conversions, establish the area basis, rounding and conditions of the particular sale. An entry without a completed sale should not be treated in an analysis as goods sold for zero.
Buyers should specify variety, crop year, the material expected after lifting and its intended use. For a standing-crop purchase, we recommend agreeing responsibility for lifting, cleaning, grading and haulage. It also matters whether inspection allows the buyer to assess uniformity and conformity with the description. A price for an area of crop does not by itself establish the unit cost of finished bulbs: assumptions about recoverable output and subsequent work are needed before comparing offers.
Sellers should prepare unambiguous variety identification, the field location, a lot description and available documents. Buyers should check plant-health requirements, variety rights and suitability for their destination market. These are transaction-specific points to resolve, rather than a single set of conditions asserted to apply to every CNB sale. The operator’s product contacts help direct an enquiry to the relevant specialist. Published results are useful comparative evidence, but an actual purchase needs the current catalogue and the conditions for that auction. A historical result cannot guarantee equivalent crop quality, yield or delivery arrangements.
