DSCSA at wholesale volume.
Under the Drug Supply Chain Security Act, a wholesale distributor must be licensed, trade only with authorized partners, pass package-level transaction data electronically, verify saleable returns and answer FDA requests within one business day.
Wholesale distributors sit at the choke point of DSCSA: everything flows through them, both directions. Unit-level verification of saleable returns, electronic transaction data on every shipment, and authorized-trading-partner checks — all at millions of units a day. At wholesale volume, a small exception rate is a big room full of quarantined totes.

The middle of the chain carries both directions.
Verify saleable returns before resale
Returned product re-entering inventory has its product identifier verified — at wholesale scale, thousands of verifications a day, each one a data lookup that must be fast.
Transaction data both ways
Receive TI/TS electronically from manufacturers, pass it downstream to dispensers — and refuse product whose data doesn't match what's on the dock.
Authorized trading partners only
Every counterparty checked against licensure — buying from or selling to an unauthorized partner is itself a violation.
Suspect product at scale
Quarantine, investigate, verify, notify — with processes that work when the suspect lot is spread across twelve DCs.
The timeline, as it stands.
Wholesale obligations are fully in force. The operational frontier is exception handling: mismatched EPCIS events and orphaned serials are where compliance cost actually lives.
Three moves that de-risk the deadline.
Measure your exception rate honestly
Count the shipments held for data mismatches per week. That number times handling cost is your real DSCSA bill — and the number to attack.
Make returns verification a scan
Dock-door verification against the serialized record should take seconds per tote, not a back-office queue.
Stress-test the recall path
Pick a random lot and produce every downstream ship-to in under an hour. If you can't, the gap will surface during an actual event.
Verification speed is the whole game.
Aeroz layers chip-verified unit identity onto existing serialization, so returns and suspect checks resolve with a dock read against an append-only EPCIS 2.0 log, at tote or unit level. Exceptions fall because physical product and data can be matched without opening boxes, and recalls narrow to exact units in exact DCs.
DSCSA for wholesale distributors, answered.
What must distributors verify on saleable returns?
The product identifier of returned product before it can be resold — confirming the unit is legitimate and its data intact. At volume this only works as an automated, scan-driven check.
What are ATP obligations?
Trading only with authorized trading partners — properly licensed or registered manufacturers, wholesalers, dispensers and 3PLs. Counterparty status must be checked and documented.
Where do distributor systems actually strain?
Exception handling: EPCIS events that don't match physical receipts, orphaned serials from aggregation drift, and verification queues during returns surges. The fix is faster physical-to-data matching, not more people.
Do we need a serialization platform to use Aeroz?
No. Aeroz runs on its own. Chip identity binds to the serialized unit and verification becomes a read instead of a research task. If you already run an L4/L5 stack, Aeroz connects to it through EPCIS 2.0.
