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...
Which Incoterms do you support?
Top commonly trades on FOB (Shanghai / Guangzhou), CIF / CFR, EXW, and DAP / DDP by agreement. FOB is default for most B2B buyers (you arrange main freight and insurance).For buyers wanting simplicity we can quote CIF/CFR (we arrange freight) or DAP/DDP (delivered to your door with duties handled). The chosen Incoterm is stated on the proforma and affects who books freight and where risk transfers.Tell Top your preference and we will align documentation.
What IFRA and allergen compliance should buyers observe?
Jasmine sambac concrete contains indole and benzyl compounds — natural, but buyers should screen under IFRA (jasmine class has indole-related notes) and the EU 26-allergen list (benzyl alcohol, linalool, etc.) and follow the Cosmetic Safety Technical Specification (China) and EU 1223/2009 allergen labelling. Top supplies the material and supports the safety review; for sensitive categories (baby, leave-on near mucosa) keep levels conservative.Food use follows GB 2760-2024 / EU 1334/2008 / US 21 CFR, not IFRA. The buyer's formulator remains responsible for end-product compliance.Because the concrete carries residual solvent if not fully recovered, Top confirms solvent residue (GB 5009.262) so the...
Do you test heavy metals and residual solvents?
Yes. Every lot is heavy-metal screened (Pb, As, Hg, Cd per food-safety / Cosmetic Safety Technical Specification limits) on the COA.Because extraction uses food-grade solvent, we verify solvent residue with GB 5009.262 (not detected) — this is critical for a concrete, and Top reports it explicitly per lot. For cosmetic/food use we confirm residue is within the target market's limit.We do not release a lot exceeding heavy-metal or solvent-residue limits. Buyers can request the specific panel and third-party verification.
Is this jasmine sambac concrete Halal and/or Kosher certified?
Top can supply Halal and Kosher certificates on request for dedicated lots (jasmine is generally compatible with both; certification is issued per batch / per request). Tell Top at order time so we reserve a certified run and the correct documentation.If you only need a general statement, we can issue a plant-origin declaration. Certificates are provided as PDF with the shipment or separately by email.
Is this jasmine sambac concrete food-grade, and is there a FEMA GRAS number?
Jasmine is a traditional edible flower (jasmine tea, pastries) and jasmine concrete/absolute are traditional flavour bases. In China, food use is governed by GB 2760-2024 jasmine class (verify the specific listing and any provincial rule).In the US, FEMA 2598 is the jasmine (class) flavour number (Top cites it, per COA) and US food use follows 21 CFR 182.20 GRAS framework. Top supplies documented lots and the food-use citation; the buyer confirms the exact food category and market eligibility.Because concrete contains flower wax and residual solvent risk, food use should specify the de-waxed absolute-grade or confirm solvent-residue compliance per the target...
