Can we arrange third-party inspection (SGS / Eurofins)?
Yes. Top supports third-party inspection and testing by SGS, Eurofins or an agreed lab at buyer cost.
Options
Pre-shipment sampling plus lab verification (GC-MS β-ionone fingerprint, melting point / refractive index, moisture, heavy metals, solvent residue), and factory audit.
We share the lot number and retention sample so the inspector draws representatively. Tell Top which parameters and which lab, and we will coordinate the appointment and incorporate the result into the shipment documents.
For osmanthus, we particularly recommend the GC-MS β-ionone fingerprint to confirm natural profile, plus a solvent-residue check.
