Can buyers audit or visit your facility?

Yes. Top welcomes factory audits and visits (virtual or on-site) for qualified B2B buyers — covering the solvent-extraction line (salting/color-protection, extraction vessel, solvent recovery, dewaxing/crystallizer, vacuum concentrator), QC lab (GC-MS β-ionone fingerprint, GC-HS solvent residue, refractometer/melting point, Karl Fischer, sensory panel), packaging and traceability (flower ledger).

We can show the O. fragrans (var. thunbergii, Guilin) sourcing and the Q/XXXX conformance documentation, and clearly present osmanthus concrete as distinct from the de-waxed osmanthus absolute (GD01). Audit requests should be made in advance so we prepare the line, documents and (where needed) an NDA.

A successful audit builds the basis for an LTA and better pricing.
