Can buyers audit or visit your facility?

Yes. Top welcomes factory audits and visits (virtual or on-site) for qualified B2B buyers — covering the aqueous-extraction line (washing & pitting, extraction vessel, centrifuge/filter, vacuum concentrator, refining tank, UHT sterilizer, aseptic filler), QC lab (refractometer Brix, titration total acid, HPLC flavonoids + patulin per GB 5009.185, micro, heavy metals), packaging and traceability (fruit ledger).

We can show the Crataegus pinnatifida sourcing (northern China) and the Q/XXXX conformance documentation. 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.
