Chain of Custody
Plants for planting can cross suppliers, borders, inspection stations, carriers, receiving docks, isolation areas, nurseries, propagation benches and final fields. A chain-of-custody system preserves the identity and status of each lot or group as it moves. It does not determine admissibility, diagnose pests, authorize release or replace phytosanitary documents and official instructions.

Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
Follow living material
without rewriting official status.
USDA APHIS explains that imported plants and seeds may be subject to permits and conditions, and that plant inspection stations review documentation and inspect propagative material before release. Exact requirements depend on commodity, origin, destination and current official systems.
A useful operational record therefore preserves scientific and commercial identity as supplied, lot or shipment identifiers, origin, quantities, documents, carrier events, inspection and official status, receipt condition, internal isolation, propagation genealogy, destination, losses and corrective actions while clearly separating farm records from government determinations.
02 / Custody loop
Qualify source, receive status,
propagate and close destinations.
01SOURCE / 01Capture supplier and material identitySupplier and nursery, scientific and commercial name as documented, cultivar or clone where applicable, propagule type, lot or group, quantity, origin and production site when supplied, order, intended use and responsible importer or receiver
02SHIP / 02Preserve shipment and official evidenceCarrier and route, packing list, invoice, permit and certificate identifiers where applicable, seals, ports or stations, inspection and sample events, official hold or release status, required destination, notices, conditions and document versions

04 / Practice
Make status impossible
to infer from location alone.
Model holds and releases explicitly
Record authority, scope, time, affected material, conditions, permitted actions, notices and closure; physical movement never changes status automatically.
Preserve propagation genealogy
Connect parent lots to batches, cuttings, grafts, divisions, transplants, growing areas, losses and destinations with responsible people and time.
Make affected destinations findable
Support rapid identification of remaining material, derived batches, internal locations, fields or customers, contacts, notices, responses and final disposition under approved authority.
05 / Boundaries
Traceability cannot authorize
movement or release.
No import, export, quarantine, inspection, treatment, release, nursery, plant-health or movement requirement is provided.Use current APHIS and destination-authority systems plus qualified regulatory, customs, nursery, plant-health and legal expertise.
Common or commercial names can be ambiguous and scientific names can change.Preserve the supplied name, source document, identifier, taxonomic authority where used, corrections and uncertainty rather than silently normalizing identity.
Absence of visible symptoms is not proof of pest freedom.Use authorized inspection, sampling and diagnostic processes, biosecurity controls, official status and qualified decisions.
