yellow-chrysanthemum-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...

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.

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.
