What we keep on file and for how long
Every order is documented with a permanent, customer-visible chain-of-custody record.
Per order we keep
- Lot number assigned at fulfillment.
- Certificate of Analysis (COA) from the qualifying lab.
- Carrier, tracking number, and delivery confirmation.
- Compliance-disclaimer attestation (where the SKU is an investigational compound).
- Your account ID and license-of-record at the time of the order.
Retention
- Order records, lot assignments, COAs, shipping records: 7 years from the date of the order.
- License documents + verification audit trail: 7 years beyond account closure.
- Invoice and payment records: 7 years.
- Compliance-disclaimer attestations: 7 years beyond the related order.
- Account profile data: active life of the account plus 24 months.
If a regulator or your own compliance department requests sourcing documentation, the trail starts on your order detail page and is export-ready (PDF for the COA, CSV for the chain-of-custody record).
Full details at the Compliance posture §04.
