Frequently asked questions

Which GMP grade maps to which ISO class?

Grade C ≈ ISO 7 (Class 10,000), Grade D ≈ ISO 8 (Class 100,000). We design pressure cascades and air-change rates per grade and verify with third-party testing at handover.

Do you supply validation documentation?

Yes — DQ drawings, airflow schemas, filter certificates and third-party particle/microbial reports are part of standard handover, formatted for QA review.

Can you match an existing facility's URS?

Send your URS — our engineers return a compliance matrix showing how each requirement is met, exceptions flagged, within 48 hours.

Do you build outside China?

Yes — supervision teams for Vietnam, Thailand, Indonesia, Malaysia and the Philippines; equipment-and-drawings packages for other regions.
