Can we arrange third-party inspection (SGS / Eurofins)?
Yes. Top supports third-party inspection and testing by SGS, Eurofins or an agreed lab at buyer cost. OptionsPre-shipment sampling plus lab verification (Brix, total sugar, total acid, cAMP/polysaccharides, patulin per GB 5009.185, heavy metals, micro), and factory audit.We share the lot number and retention sample so the inspector draws representatively. Tell Top which parameters and which lab, and we will coordinate the appointment and incorporate the result into the shipment documents.For jujube, we particularly recommend the patulin (GB 5009.185) plus cAMP/polysaccharide HPLC to confirm natural profile and safety.
What is your sustainability and responsible-sourcing approach?
Top sources Ziziphus jujuba fruit through contracted northern-China orchards (Shanxi, Shaanxi, Hebei, Shandong, Xinjiang) with a fruit-to-concentrate ledger (origin → harvest → extraction → concentrate). Jujube is a farmed orchard crop (not wild-harvested, not CITES), so sourcing is traceable and sustainable by cultivation.The aqueous route uses purified water and cleanroom filling (low environmental load, no organic solvent). Buyers can request a supply-chain / origin declaration and (for dedicated lots) organic certification.We aim for transparent, documentable sourcing rather than vague natural claims. Because jujube is a seasonal, weather-sensitive crop, we emphasize fair, documented fruit sourcing and buffer stock to protect buyers...
How do you handle shipping and freight?
Top ships worldwide by sea or air under the agreed Incoterm. For sea we use FCL / LCL from Shanghai / Qingdao; for air, DHL / FedEx / airline cargo.Red date concrete is low-hazard (food concentrate, non-DG under normal carriage), but we still ship it with an SDS where applicable and use qualified forwarders. We provide tracking and can handle door-to-door or port-to-port.Freight is quoted separately from the product FOB price; tell Top your destination port / airport and preferred mode for a quote.
What is the shelf life and how should it be stored?
Shelf Life36 months from production (sealed, cool, dark, away from air; a fruit concentrate with sugars can ferment or mould if exposed — UHT sterilization plus aseptic filling protect it; patulin risk is managed by raw-material control + GB 5009.185). Strict ProtectionKeep away from light, heat and air; store below about 4-25C (refrigeration recommended for long storage); FIFO; sealed packs.Top adds a preservative within food-regulatory limits on request and can provide a real-time + accelerated study. Re-test before the end of shelf life.The COA notes the production date and recommended storage. Because it is water-based with Brix, avoid freeze-thaw cycling.
Is red date concrete seasonal, and how does that affect availability?
Yes — Ziziphus jujuba fruits over an autumn harvest window and the fruit is perishable, so fruit supply is seasonal and crop-dependent (weather and yield swing price and availability). Because the concentrate is a processed food extract, the concentrate itself can be buffered (Top keeps some stock), but large or steady volumes need planning.Top keeps buffer stock of standard grades and contracts fruit volume; for large or steady volumes we recommend an LTA to reserve extraction slots and stabilize price against crop swings. We communicate fruit-market conditions on each quotation.
What is your sample policy for red date concrete?
Top supports evaluation with 5-10 g samples (sometimes up to about 20 g for qualified buyers), drawn from current stock or a fresh extraction, shipped with COA plus assay (Brix / total sugar / cAMP / patulin). Samples are usually charged at the sample-tier price (or free for strategic / qualified accounts) plus freight.We recommend requesting the sample from the same lot you intend to purchase so the Brix / sugar / cAMP profile and patulin status match your production batch. Sample lead time is short (stock) or aligned with the next extraction window.Tell Top your application and preferred grade...
How much do samples cost and how fast do they ship?
Sample CostThe sample-tier unit price for 5-10 g (often waived for qualified / strategic buyers) plus international freight. Lead TimeStock samples 3-7 days; if a fresh extraction lot is needed, 10-20 days (fruit sourcing plus extraction plus concentration plus QC including patulin).Top can express-ship via DHL / FedEx. As a low-hazard food concentrate, samples ship with an SDS where applicable. Provide your courier account or let Top quote the freight.
What is your returns and refund policy?
Because this is a natural, batch-specific food concentrate, returns are handled case-by-case. If Top's own lot data (COA plus assay) confirms a specification failure, we arrange replacement or refund of the affected quantity; return of unused, sealed material may be requested for verification.For buyer-side issues (wrong grade ordered, changed mind), returns are by mutual agreement and may incur restocking. All returns/refunds follow the signed contract and Incoterms; we keep the process transparent and documented.
Which plant part is the concrete extracted from?
From the jujube fruit (drupe) — flesh, after washing and pitting (the stone is removed). Top's COA states "raw material: red date fruit (Ziziphus jujuba)".Not leaf, flower or seed. The fruit is the medicinal/food part in medicine-food dual-use, and the concentrate carries the characteristic sweet, date-like, slightly caramelized note (sugars, organic acids, cyclic nucleotides).Because it is a fruit concentrate, it is a viscous liquid / paste (not a waxy floral concrete and not a volatile oil).
