What sieve grade of Hawthorn is standard for teabag filling lines?

Cut-and-sifted Hawthorn in a 2–5 mm or 3–8 mm sieve grade is the standard specification for most teabag and loose-leaf infusion filling lines. This particle size delivers efficient infusion extraction and consistent colour release while producing minimal dust that could block filling machinery. The exact cut should be confirmed against your specific filling-line tolerances; TANDOR can supply samples of different sieve grades for line trials before commercial ordering.

Can Hawthorn for EU herbal teas be gamma irradiated to meet microbial limits?

Technically yes, but in practice EU-market herbal tea brands avoid it. Under EU Directives 1999/2/EC and 1999/3/EC, any ingredient treated by ionising radiation must be declared as such on the product label—which conflicts with clean-label positioning. Steam sterilisation is the preferred alternative: it achieves equivalent microbial reduction, is compatible with EU-Organic certification under Regulation 2018/848, and requires no special labelling. TANDOR supplies steam-sterilised lots and specifies the method on the Certificate of Analysis.

What EU-Organic documentation comes with a Hawthorn shipment from TANDOR?

Each organic Hawthorn shipment is accompanied by the supplier's valid EU-Organic operator certificate (issued under Regulation 2018/848) and a transaction certificate covering that specific lot, confirming the certified status of the quantity shipped. These documents are required by your own certifying body to maintain organic chain-of-custody. Batch-level Certificates of Analysis covering microbiological parameters, pesticide residues, moisture, and heavy metals are also provided as standard.

What are realistic minimum order quantities and lead times for Hawthorn C/S?

For standard cut-and-sifted Hawthorn berry or flowering-top lots, minimum commercial orders typically start at 100 kg. Qualification samples of 1–5 kg are available prior to commercial commitment. Lead times vary by origin and season: Romanian and Balkan-origin lots generally ship within 2–4 weeks of order confirmation for in-stock grades. Because Hawthorn berry harvest runs September–October and flowering-top harvest in May–June, buyers planning year-round supply should discuss forward-order agreements with TANDOR to secure preferred grades across seasons.

Hawthorn for Herbal Tea Manufacturers

Why Hawthorn Grade and Form Matter for Tea Production

For herbal infusion manufacturers, the physical form and sieve grade of Hawthorn raw material directly determines extraction efficiency, visual consistency in the finished blend, and shelf-life performance. Whole dried berries, while useful for some functional food applications, are rarely optimal for tea: they require extended steeping times and produce inconsistent infusion colour and flavour across batches. Cut-and-sifted (C/S) material in a 2–5 mm or 3–8 mm sieve grade is the industry-standard specification for both loose-leaf infusions and filled teabags, as it balances surface-area-to-mass ratio for rapid colour and flavour release with dust reduction that would otherwise clog filling machinery.

Finely milled powder grades (below 1 mm) are occasionally requested for sachet or instant infusion formats but require dedicated equipment and dust-control measures on the production line. TANDOR sources all standard Hawthorn forms and can specify sieve grades to match the buyer's filling-line requirements.

Forms and Specifications for Infusion Use

Hawthorn Berries (Fructus Crataegi)

Whole dried: suitable for display-grade retail tin mixes; lower infusion efficiency
Cut & sifted, 3–8 mm: the most widely specified berry form for teabag and loose-leaf production; releases the characteristic mild, slightly sweet-tangy flavour and rose-amber colour characteristic of Crataegus monogyna
Powder (< 500 µm): for instant sachets or functional blend bases

Hawthorn Flowering Tops / Flowers with Leaves (Flos Crataegi cum Foliis)

Cut & sifted, 2–5 mm: aligned with the European Pharmacopoeia (Ph. Eur.) monograph for *Crataegi folium cum flore*, relevant when buyers want to reference a pharmacopoeial grade for quality positioning
Delivers a lighter, more delicate colour and a subtler, hay-like aromatic profile compared to berry cuts

Leaves Alone (Folium Crataegi)

Less commonly specified for standalone infusions; often blended with berry or flowering-top cuts to balance flavour

Colour and flavour retention: Post-harvest drying temperature and storage conditions are the primary variables. TANDOR specifies drying below 40 °C for organic lots to preserve volatile aromatic compounds and the naturally occurring oligomeric proanthocyanidins that contribute to the characteristic reddish infusion colour. Moisture content is controlled to ≤ 10 % (m/m) at dispatch, in line with general Ph. Eur. botanical raw-material guidance, to prevent mould development during transit and storage.

Tea-Grade Microbiological and Contaminant Limits

Herbal infusion manufacturers operating under EU food law (Regulation (EC) No 178/2002 and Regulation (EC) No 852/2004) must ensure raw botanical materials meet food-safety criteria before processing. Key parameters for Hawthorn tea-grade material include:

Total aerobic plate count (TAPC): typically ≤ 10⁵ CFU/g for unsterilised botanical raw material entering a production facility with a validated kill step, or ≤ 10³ CFU/g for ready-to-fill product post-sterilisation
Enterobacteriaceae: ≤ 10² CFU/g (raw)
Absence of Salmonella spp. in 25 g
**Absence of *E. coli*** (or ≤ 10 CFU/g depending on facility SOP)
Aflatoxins and ochratoxin A: within Commission Regulation (EC) No 1881/2006 maximum levels for dried herbs
Pesticide residues: compliant with Regulation (EC) No 396/2005 MRLs; for EU-Organic certified lots, the additional absence expectations of Regulation 2018/848 apply

All TANDOR batches are supplied with a Certificate of Analysis (CoA) covering these parameters from an accredited third-party laboratory, issued per individual lot.

Steam Sterilisation vs. Irradiation

This is a critical decision point for EU infusion manufacturers. Gamma irradiation is permitted in some third countries and can reduce microbial load effectively, but under EU law (Directive 1999/2/EC and 1999/3/EC), irradiated food or ingredients must be labelled as such—a significant marketing liability for branded herbal teas. Steam sterilisation (saturated steam at controlled temperature and time) is the preferred method for EU-market botanical material: it achieves the required microbial reduction without triggering mandatory irradiation labelling and is compatible with EU-Organic certification under Regulation 2018/848, provided the process is documented and the certifying body approves it. TANDOR can supply both sterilised and non-sterilised lots and specifies the sterilisation method on the CoA so buyers can fulfil their own documentation requirements.

Origin, MOQ, and Supply Realities

Hawthorn is wild-harvested or cultivated across Central and Eastern Europe (Romania, Bulgaria, Poland, Ukraine) and parts of the Caucasus. Romania is a significant origin, offering both wild-harvest certified-organic material and cultivated lots, with short logistics routes into the EU common market—reducing transit time and cold-chain risk compared to non-European origins.

As a Romania-based EU sourcing intermediary, TANDOR offers:

Multi-origin sourcing: ability to qualify alternative origins and switch between them to manage seasonal shortfalls or quality variation, without the buyer needing to manage multiple supplier relationships
Minimum order quantities typically start at 100 kg per form/grade for standard C/S lots; smaller qualification samples (1–5 kg) are available for formulation and sensory trials
Batch-level CoA: every commercial shipment is accompanied by a full analytical report—not a generic annual certificate
Flexible packaging: 5–20 kg kraft or PE-lined bags; carton-based or woven polypropylene sacks for bulk pallet shipments, labelled per buyer's intake specification
