Bulk hazelnut supplier guide for food manufacturers

1. Start with the finished application

The correct starting point is not a generic request for “hazelnuts”. State what the ingredient must do in the finished product. Whole visible kernels for premium chocolate require different visual uniformity from kernels destined for chopping, flour or paste. A roasting line may need natural kernels, while a plant without roasting capacity may require a controlled roasted profile.

Include the application, point of addition, subsequent heat treatment, desired flavour, visible appearance and expected shelf life. This helps the supplier propose an appropriate product rather than merely quoting the cheapest available lot.

2. Define the commercial product precisely

Identify the product state: natural kernel, roasted, blanched, chopped, flour, paste or in-shell. For whole kernels, specify the requested screen range and whether a tolerance outside that range is acceptable. For chopped material or flour, define particle distribution rather than relying on a single nominal size. For paste, define roast profile, texture or particle-size expectation and any flow requirements relevant to dosing.

UNECE DDP-04 is a useful commercial-quality reference for hazelnut kernels, but a buyer specification should still record the exact parameters agreed between the parties.

3. Separate quality from food-safety requirements

Commercial quality covers matters such as size, colour, flavour, skin retention, broken kernels, defects and foreign matter. Food safety covers hazards and controls, including aflatoxins, microbiological criteria where applicable, allergens, pesticide residues and traceability. Keep both groups visible in the specification so a visually acceptable sample is not mistaken for full compliance.

EU Regulation 2023/915 distinguishes hazelnuts intended for further sorting or physical treatment from hazelnuts placed on the market for the final consumer or for use as an ingredient. The declared use and applicable category must be agreed before shipment and confirmed against current legal requirements.

4. Qualify the supply chain

Ask who grows, aggregates, processes, tests, packs and exports the product. Confirm how lots are identified and whether traceability links the finished lot to incoming material and processing records. Supplier approval may include questionnaires, available certification, audit evidence, sample review, certificates of analysis and escalation procedures.

Certification can support due diligence, but it does not replace a product-specific specification, representative sampling or buyer verification. The strength of the system lies in how controls are applied to the actual lot.

5. Plan packaging and logistics around the factory

Common dry-product formats include kraft or polypropylene sacks, vacuum packs and big bags. The right format depends on oxidation sensitivity, warehouse conditions, opening frequency, line handling and batch size. Paste may require buckets, barrels or drums compatible with the buyer’s handling equipment.

Confirm net weight, liner, closure, pallet pattern, maximum pallet height, label content, lot coding and storage instructions. Agree the Incoterm, delivery point, call-off pattern, lead time and responsibility for import or customs formalities in the written offer.

6. Compare total delivered value

A unit price is comparable only when origin, crop or production reference, product state, calibre, tolerances, packaging, testing, Incoterm and destination are equivalent. Differences in usable yield, processing loss, breakage, rework, storage and line efficiency can outweigh a small price difference.

For recurring programmes, compare continuity of supply, responsiveness, complaint handling and the supplier’s ability to reproduce an approved sample—not only the first quotation.

7. Run a controlled approval process

A practical sequence is: written brief, supplier clarification, representative sample, internal trial, specification agreement, commercial offer and first-lot verification. Retain an approved reference where useful. Define who can approve deviations and what happens if analytical or sensory results fall outside agreement.

Before the first shipment, align product name, lot definition, documents, sampling, release status, packaging, delivery window and contact points for quality and logistics.
