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.
Can we set up a long-term supply agreement (LTA)?
Yes. For steady volume, Top recommends an LTA / annual framework that reserves solvent-extraction slots and jasmine-flower sourcing ahead (ideally before the flowering season), stabilizes price (with a review mechanism to manage the weather/crop-sensitive jasmine market) and prioritizes your allocation.The LTA specifies grade (Q/XXXX or your spec), pack size, volume bands, lead time, quality agreement and complaint handling. Buyers under an LTA get buffer-stock priority and a dedicated contact.Because jasmine sambac concrete is seasonal and crop-sensitive, an LTA is the most reliable way to secure consistent supply and predictable cost — contact Top with your annual forecast.
What is the lead time from order to delivery?
Lead TimeBuffer-stock standard grade 3-7 days to dispatch; fresh extraction 10-20 days (flower sourcing plus extraction plus dewaxing plus QC plus documentation).After dispatch, transit depends on incoterm (FOB Shanghai, sea to EU/US about 25-40 days; air 3-7 days). Top gives a firm dispatch date on the proforma and keeps the buyer updated.Because jasmine is seasonal and weather/crop sensitive, order ahead — especially before the flowering season — to lock price and availability.
What defines the composition of jasmine sambac concrete?
It is a floral wax + aroma concentrate whose signature is the benzyl alcohol / benzyl acetate / indole series (the classic heady, indolic, sweet, waxy jasmine character) plus cis-jasmone, methyl jasmonate (the "true jasmine" trace notes), linalool, benzyl benzoate, and minor flower wax esters. Top fingerprints benzyl alcohol + benzyl acetate + indole by GC-MS as the authenticity marker (synthetic jasmine or blends lack the natural ratio, especially the jasmone/jasmonate trace complex).The concrete also contains flower wax, so it is a paste, not a clear oil. Each COA reports the GC floral fingerprint and the wax/non-wax balance; the identity...
