For a chocolate or confectionery manufacturer, hazelnut is rarely a shopping decision and almost always a specification decision. The origin question is largely settled — Türkiye is the world's largest hazelnut exporter and the default input for most of the European industry — so the useful conversation is about what exactly is being bought, documented how, and contracted when. This guide covers the three points where sourcing conversations actually succeed or fail.
Calibre is the specification most quotations skip
Kernel calibre drives both how the product looks and how it behaves in production. Whole kernels destined for pralines or bars need a consistent diameter, because coating thickness and bite depend on it; a wide calibre spread produces visible inconsistency in the finished piece. Chopped and granulated grades need a controlled particle distribution, or a filling separates in the mould. This is why a quotation naming only "hazelnut kernels" is not comparable with one that names a calibre band — two prices that look far apart are frequently quoting different products. The same discipline applies to roasting level, which is a specification rather than a preference: it shifts colour, aroma intensity and oil release, all of which reach the finished bar.
The formats, and where volume actually sits
Five formats cover almost all confectionery demand: raw kernel, roasted, blanched, chopped or granulated, and paste. Blanched kernels are chosen where skin particles would be visible in a light-coloured product, which makes them a standard requirement in white and milk applications. Paste is where the largest volumes sit, feeding spreads and fillings, and it carries its own specification questions — roast level, particle fineness, and whether the paste is pure hazelnut or extended. A buyer who has settled these points before requesting quotations gets comparable numbers back; one who has not spends the first round discovering that the offers describe different goods.
