How do you handle a quality complaint or dispute?
Top treats complaints seriously:Notify us within the validity window with the lot number, COA reference and the issueWe review the retained sample and the batch COA / GC-MS / sensory resultIf a genuine non-conformance is confirmed (e.g., off Q/XXXX, weak benzyl/indole profile, excessive solvent residue), we offer replacement, credit or refund per the contractFor disputes we can involve a third-party lab (SGS, Eurofins) with costs allocated by outcome.Keep the original pack sealed where possible. Our aim is a fair, documented resolution — we do not argue against our own lot data.
What documents (COA, GC-MS, MSDS) ship with each order?
Every Top order ships with:COA (batch-specific, conforming to Q/XXXX — melting point, refractive index, yield, solvent residue, species + "fresh flower / solvent concrete" stated)GC-MS report (benzyl alcohol / benzyl acetate / indole fingerprint)MSDS / SDS (CLP for EU)Commercial invoice plus packing listCertificate of originHealth certificate on requestFood-use note (GB 2760-2024 jasmine verification) for food buyers.Optional third-party test (SGS, Eurofins) at buyer cost. All documents in EN (and CN on request).
Is jasmine sambac concrete subject to CITES controls?
No. Jasminum sambac is a widely cultivated ornamental / flowering shrub, not listed in CITES Appendices — no CITES permit required. It is a farmed floral crop (Guangxi plantations).Top ships the standard commercial + food/cosmetic-export documents (invoice, packing list, COA, MSDS/SDS, certificate of origin, health certificate on request). Normal food-safety and cosmetic regulations apply, but no CITES hurdle exists for jasmine sambac concrete.
What certificates and accreditations can you provide?
Top can provide: ISO 9001 (quality management), Halal and Kosher certificates (on request — jasmine is generally compatible), organic for dedicated lots (on request), a non-GMO declaration, certificate of origin, and a health certificate for food import on request. For EU we supply CLP-format SDS; for US we reference FEMA 2598 / 21 CFR 182.20.Third-party test reports (SGS, Eurofins) at buyer cost. Confirm available certificates at order time — some are per-lot / per-request rather than blanket.
What botanical species does jasmine sambac concrete come from, and where is it sourced?
Jasmine sambac concrete is the solvent extract of the flowers of Jasminum sambac (L.) Aiton — the "Xiao-hua molihua" (small-flower jasmine / Arabian jasmine), one of the classic jasmine species used for the world-famous jasmine concrete / absolute. Top sources fresh jasmine sambac flowers from Guangxi (Hengxian / Hengzhou, the "jasmine capital of China") and adjoining regions, the traditional jasmine-flower belt.Top declares the botanical name on every COA. Note this is a solvent-extracted concrete (floral wax + the heady jasmine aroma concentrate) of fresh jasmine blossoms — a natural, flower-origin material, not a distilled oil.Top keeps the species declaration so...
Do you supply diluted or blend-ready jasmine sambac concrete?
Yes. Beyond the neat concrete, Top can supply diluted forms (for example, pre-dissolved in a carrier oil such as jojoba / MCT, or in food-grade ethanol at a defined percent) for easier handling and lower-cost trials, or a pre-blended base per your formula.Because this is a waxy concrete (not a volatile oil), dilution is by melting and blending with carrier oil or ethanol. Dilution medium and concentration are agreed per order and stated on the COA.Note that dilution changes the measured specification window, so the COA always declares the actual concentration and base. Neat lots remain the default for buyers...
How do you ensure batch-to-batch consistency and traceability?
Top controls consistency through Q/XXXX and per-batch GC-MS benzyl / indole floral fingerprint matched to the reference profile: each lot is matched (melting point, refractive index, yield within band, benzyl-alcohol/acetate/indole ratio present). Traceability runs flower origin → extraction → concrete with a lot-specific ledger and retention sample.If your application needs tight tolerances, tell Top and we can select lots from the same orchard/harvest or blend to a target floral profile. Every shipment carries a lot number linking to the COA and GC-MS on file.Top shares the QC ledger with GD27 jasmine sambac essential oil for fresh-flower continuity.
What does jasmine sambac concrete look and smell like?
AppearanceA soft, waxy, paste-to-semi-solid mass, orange-brown to deep brown (a true "concrete" — it contains floral wax, so it is not fluid at room temperature; warm to soften). OdourThe classic intense, indolic, sweet, waxy, rich jasmine character — the heady "white floral" signature, not a single-note synthetic.Because solvent extraction captures the full floral complex (benzyl alcohol / benzyl acetate / indole / cis-jasmone / methyl jasmonate), the aroma is true natural jasmine sambac, not a simplified fragrance. Sensory evaluation follows an in-house panel; Top provides the odour description on the COA and can supply a reference sample. (Reminder: it is...
What after-sales support do you provide?
Top provides ongoing support: lot traceability and re-test within shelf life using the retention sample, documentation re-issue (COA / SDS / origin / health cert copies), formulation advice (melting/dilution in carrier oil or food-grade ethanol, grade selection for stability, food vs cosmetic labeling, oxidation-control note for this waxy, aroma-sensitive concrete) and a responsive complaint channel. For LTA buyers we assign a dedicated contact and periodic review of grade consistency.We treat the relationship as long-term — the after-sales step is where we protect your production continuity, not an afterthought.
