What is the lead time from order to delivery?
Lead TimeBuffer-stock standard grade 3-7 days to dispatch; fresh batch 10-20 days (sourcing plus processing 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.
What defines the composition of michelia-alba-concrete?
It is a floral-sesquiterpene concrete (benzyl alcohol / benzyl acetate / linalool-type notes), a fragrance class whose identity markers are benzyl alcohol, benzyl acetate and linalool-type florals as the key signature. Top fingerprints GC-MS for the benzyl-ester / linalool floral fingerprint as authenticity/quality markers.Top fingerprints the floral profile and screens for synthetic floral or solvent adulteration. Each COA reports benzyl-acetate content, solvent residue (GB 5009.262), heavy metals and micro; the identity is the natural Michelia alba DC. (white champaca) profile, not a single volatile oil.
Which Incoterms do you support?
Top commonly trades on FOB (Shanghai / Qingdao), 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?
michelia-alba-concrete is a fragrance/flavour material (IFRA class as applicable), so IFRA (which governs fragrance materials) is largely not the controlling framework; food use follows China food-safety frameworks (GB 2762/GB 2760) and, for export, FDA 21 CFR / EU food law, and cosmetic use (if any) follows the Cosmetic Safety Technical Specification and EU 1223/2009. Not a major allergen in CN/EU/US lists; Top supplies composition, the buyer's formulator handles labelling.Top supplies the material and supports the safety review; the buyer's formulator remains responsible for end-product compliance. For export, Top provides CLP-format SDS and the COA + assay + food-use statement so...
Do you test heavy metals and residual solvents?
Yes. Every lot is heavy-metal screened (Pb, As, Cd, Hg, Cu (GB 2762)) and microbiologically checked (total plate count, coliforms, mould & yeast, pathogens) on the COA.If a solvent route is used, solvent residue is verified per GB 5009.262 (typically non-detect for physical routes). We do not release a lot exceeding heavy-metal, micro or solvent-residue limits.Buyers can request the specific panel and third-party verification.
Is this michelia-alba-concrete Halal and/or Kosher certified?
Top can supply Halal and Kosher certificates on request for dedicated lots (plant/fungus origin and generally compatible; 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 source declaration. Certificates are provided as PDF with the shipment or separately by email.
Is this michelia-alba-concrete food-grade, and is there a FEMA GRAS number?
Michelia concrete is positioned as a fragrance raw material (perfumery/tea-scenting), not a food flavour; food use would require separate food-grade qualification. No FEMA GRAS number for the concrete.Top supplies documented lots and the food-use citation; the buyer confirms the exact food category and market eligibility. The buyer confirms the intended use and any food-grade qualification with their own compliance team.
