What is your production capacity for jasmine sambac concrete?
Capacity is solvent-extraction-slot plus jasmine-flower-supply dependent: Top allocates extraction runs across committed orders. Jasminum sambac flowers are a low-yield, night-fragrance crop, so annual volume is naturally limited and weather/crop sensitive.Large volumes are feasible but need lead-time planning, ideally ahead of the flowering season. We keep a small buffer of standard grades and recommend an LTA / annual framework for steady buyers so extraction slots and flower sourcing are reserved ahead.Tell us your annual volume and we will size the allocation and confirm lead time.
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...
