What factors influence the jasmine sambac concrete price?
Main drivers:Grade — standard vs de-waxed absolute-gradeBenzyl / indole floral-fingerprint strengthOrganic certificationFlower feedstock cost (seasonal, weather/crop dependent, night-harvest logistics)Solvent extraction + dewaxing costPack size and volumeCurrency / freight.FX and freight quoted separately. Top explains the drivers on each quotation, and flags that jasmine 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 GC-MS benzyl / indole fingerprint, melting point, moisture, solvent residue for jasmine sambac concrete).PSI also confirms correct sealed / low-oxygen 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?
Jasmine sambac concrete is a soft, waxy, paste-to-semi-solid aromatic mass (orange-brown to deep brown, typical of jasmine concrete), with the characteristic intense, indolic, sweet, waxy jasmine scent. Typical window (each COA states the measured batch value): melting point within the concrete range (it softens/melts on warming); refractive index per the concrete; yield / non-wax content declared; solvent residue not detected (GB 5009.262).Insoluble in water; soluble in ethanol and most oils; partly soluble in fixed oils. Because it is a concrete (waxy), it is dosed/melted and diluted rather than used neat.Top conforms to Q/XXXX and reports the floral fingerprint per batch.
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.
What packaging materials and sizes are available?
Because jasmine sambac concrete is a waxy, aroma-sensitive material (the indolic floral can dull / the wax can oxidize on exposure), packaging favors light-protected, sealed, low-oxygen formats: sealed foil pouches (100-500 g) for premium lots, aluminium cans (1 kg), and food-grade drums (5 kg, 25 kg). We pack sealed, labelled, and (for long storage) nitrogen-flanked or with oxygen absorbers.Keep away from heat and light. Damaged-pack claims are handled per the Incoterms and our complaint process.
Is this jasmine sambac concrete organic or wildcrafted?
Jasmine sambac is a cultivated flowering shrub (wildcrafted does not apply). Organic certification (EU 2018/848, NOP / USDA, or equivalent) can be arranged for dedicated lots from certified-organic jasmine orchards, subject to segregated handling and lead-time / premium.Conventional (non-organic) lots are the default. Top can issue a non-GMO declaration; the COA states whether a lot is organic-certified or conventional.For organic jasmine concrete, the flower sourcing and extraction must be under organic control — tell Top early so we reserve a certified run.
What is your order process and typical steps?
Typical flow:Inquiry with grade / volume / pack / destinationTop sends proforma invoice plus FOB quote plus specs (Q/XXXX)Buyer confirms and pays deposit (or opens L/C)Top produces / picks stock, runs QC plus GC-MS plus sensory, issues COAShipment with full documentsAfter-sales (traceability, re-test, complaint channel).For new buyers we may start with a sample order. Lead times follow the agreed schedule.Top keeps one point of contact so the buyer always knows the order status.
Is there a national or ISO standard for jasmine sambac concrete?
There is no single GB/T or QB/T product standard for jasmine sambac concrete (std.samr.gov.cn has no entry) and no dedicated ISO (international none for jasmine concrete). Top builds the spec on: a CAFFCI group / association standard (verify current) for jasmine concrete/absolute, the enterprise standard Q/XXXX (melting point / yield + benzyl-alcohol/acetate/indole GC fingerprint + solvent residue), and GB 2760-2024 (food-use verification). BackgroundGB/T 22292-2008 (jasmine tea) informs the raw-flower system. MethodsGB/T 11538-2006 (GC), GB 5009.262 (solvent residue), GB/T 39010-2020, GB/T 14454.2-2008, GB/T 14455.5-2008. ISO 92352013 covers "concrete" terminology.Buyers may name Q/XXXX as acceptance basis. Top keeps a shared QC ledger...
What is your minimum order quantity (MOQ)?
MOQ1 kg (samples 5-10 g available).Because jasmine sambac concrete is a processed floral material (not an endangered-species material, and not CITES), trial quantities are supported. Standard Commercial Packs1 kg (aluminium can / sealed foil), 5 kg and 25 kg drums.Recurring / contract volumes get priority allocation. If you need below 1 kg for lab evaluation, contact Top — we may supply a paid micro-sample.MOQ and pack options are confirmed on the quotation.
