What regulatory support and documents do you provide for import?
Top supports import compliance with: COA (Q/XXXX conformance) plus assay (Brix / total acid / flavonoids / patulin per GB 5009.185) plus sensory sheet, CLP-format SDS (EU), certificate of origin, and references to the relevant frameworks — China: GB 17325-2015 (concentrate), GB 2761-2017 patulin limit (hawthorn-class mandatory), GB 5009.185 (patulin assay), GB 5009.8 (sugars), GB/T 31121-2014 (fruit-veg juice), ChP 2020 Vol I Hawthorn (medicine-food dual-use), GB/T 14454.2-2008; International: EP/USP hawthorn monograph (verify), WHO monograph, EU 1334/2008, FDA 21 CFR, CLP 1272/2008. For market-specific needs (health / phytosanitary cert, Halal, organic) tell Top early.We document that this is an aqueous hawthorn...
Can you re-test or re-analyze a lot after delivery?
Yes. Top keeps a retention sample for every lot and can re-test within the shelf life on request (Brix, total acid, total flavonoids, patulin per GB 5009.185, micro, heavy metals).If a buyer disputes a result, we compare our retained-sample data with the original COA; a third-party lab (SGS, Eurofins) can be engaged for an independent read, with costs allocated by outcome. Re-testing protects both sides and is a standard part of our traceability commitment.
What quality control and in-house lab capabilities do you have?
Top operates in-house QC with: refractometer (Brix / soluble solids), titration unit (total acid), HPLC (total flavonoids — vitexin/hyperoside, and patulin per GB 5009.185), GC/assay for sugars (GB 5009.8), plus pH, microbiology (plate count, coliforms, mould/yeast) and heavy metals (food-safety). Out-of-spec lots are blocked.We can arrange third-party verification (SGS, Eurofins) at buyer cost and keep retention samples for re-testing within shelf life. The patulin assay (GB 5009.185) is mandatory for hawthorn class and run on every lot.
How do you guarantee purity and authenticity of hawthorn concrete?
Authenticity is guaranteed byQ/XXXX conformance andPer-batch Brix / total-acid / total-flavonoid assay plus patulin not detected plus the COA species + "hawthorn fruit / aqueous concentrate" declaration (Crataegus pinnatifida, distinct from sugar-water or other fruit concentrate padding).Top does not dilute with sugar-water or pad with other fruit concentrates; the COA states 100% pure hawthorn fruit concentrate (or the agreed dilution). The natural malic/citric acid ratio with the flavonoid (vitexin/hyperoside) pattern is the authenticity proof — sugar-water or other-fruit padding lacks this complex.Lots failing the profile or the patulin/micro limits are blocked. For high-assurance needs we offer third-party verification (HPLC flavonoids...
What is your production capacity for hawthorn concrete?
Capacity is extraction+concentration-slot plus hawthorn-fruit-supply dependent: Top allocates extraction runs across committed orders. Crataegus pinnatifida is a seasonal orchard crop, so annual volume is crop-dependent (weather and yield swing price and availability).Large volumes are feasible but need lead-time planning, ideally ahead of the harvest season. We keep a small buffer of standard grades and recommend an LTA / annual framework for steady buyers so extraction slots and fruit sourcing are reserved ahead.Tell us your annual volume and we will size the allocation and confirm lead time.
What factors influence the hawthorn concrete price?
Main drivers:Grade — Brix / total-acid / flavonoid targetFlavonoid strength (medicine-food dual-use value-add)Organic certificationFruit feedstock cost (seasonal, crop dependent)Aqueous-extraction + concentration + UHT/aseptic costPack size and volumeCurrency / freight.FX and freight quoted separately. Top explains the drivers on each quotation, and flags that hawthorn is a market-sensitive seasonal crop.
Do you allow pre-shipment inspection (PSI) before loading?
Yes. Buyers or their inspector may perform pre-shipment inspection at Top's facility or the forwarder's warehouse before loading — verifying pack integrity, net weight, lot numbers, labelling and sealing, and drawing samples for independent lab tests (including Brix, total acid, total flavonoids, patulin for hawthorn concrete).PSI also confirms correct sealed / low-oxygen food-grade packing. Top schedules PSI into the lead time and provides access to the lot and documents.If PSI finds a discrepancy, we resolve it (re-pack, re-test, replace) before the cargo is booked. PSI is coordinated alongside the agreed Incoterm.
What are the typical physicochemical specifications?
Hawthorn concrete is a viscous, reddish-brown to yellow-brown to brown liquid/paste, with the characteristic tart, fruity hawthorn aroma and taste. Typical window (each COA states the measured batch value within Q/XXXX): soluble solids (Brix) declared (e.g., 40-65 Brix for a concentrate); total acid (as malic acid) within band; total flavonoids declared (medicine-food dual-use value-add); pH within fruit-concentrate range; patulin not detected (GB 2761 / GB 5009.185).Water-soluble, not an oil; soluble in water and aqueous systems. Because it is a fruit concentrate (not a waxy concrete or oil), it is dosed into food/beverage systems by weight/volume.Top conforms to Q/XXXX and reports...
What payment terms do you offer?
Top offers flexible terms by partnership stage: T/T (30% deposit plus 70% against B/L copy, or 100% prior for small orders), L/C at sight for established B2B buyers, and negotiated terms for long-term contracts / LTAs. For first orders we typically require advance payment or a confirmed L/C. Samples are usually paid upfront (often net, sometimes free for qualified buyers).Tell Top your preferred method and we will align the contract; payment terms are stated clearly on the proforma invoice.
