DSCSA terms explained for pharmacies in plain English.
DSCSA comes with a lot of letters.
TI.
TS.
TH.
EDDS.
For a busy pharmacy, those terms can make DSCSA feel more complicated than it needs to be.
But the basic idea is simple.
DSCSA requires certain prescription drug transaction records to move through the supply chain so trading partners can trace product, verify information, identify suspect product, and show what happened when someone asks.
As Jim Shaver, Managing Director at Advasur, developer behind PRS DSCSA 360, puts it: “DSCSA acronyms are not the hard part. The hard part is making sure the pharmacy can receive the data, keep the records, and show what happened.”
That is why TI, TS, TH, EPCIS, and EDDS should be understood as part of a working pharmacy process, not just terms to memorize.
What is TI?
TI means Transaction Information.
This is the basic product and shipment information that comes with a covered prescription drug transaction.
TI may include information such as:
- Product name
- Strength and dosage form
- NDC
- Lot number
- Quantity
- Transaction date
- Shipment date
- Business names and addresses of the trading partners involved.
In plain English, TI helps answer:
What product moved, when did it move, how much moved, and who was involved?
For pharmacies, TI matters because it is part of the product tracing record that may need to be retained and retrieved later.
What is TS?
TS means Transaction Statement.
The Transaction Statement is the trading partner’s statement that certain DSCSA requirements were met.
In plain English, TS helps answer:
Is the seller saying this transaction meets the required DSCSA conditions?
For pharmacies, TS matters because it is part of the required transaction record. The pharmacy needs a way to receive it, retain it, and find it later when needed.
What is TH?
TH means Transaction History.
Transaction History refers to prior transaction information for the product as it moved through the supply chain.
Historically, TI, TS, and TH were often discussed together.
As DSCSA moves into enhanced electronic tracing, the practical focus is now more heavily on secure, interoperable, electronic exchange of required transaction information and transaction statements.
In plain English, TH helps answer:
Where has this product been before this transaction?
For pharmacies, the important point is to understand the term, but also recognize that DSCSA processes have evolved toward electronic package-level tracing.
What is EPCIS?
EPCIS stands for Electronic Product Code Information Services.
That is a technical name, but the practical meaning is easier.
EPCIS is a common electronic format used to exchange serialized DSCSA transaction data between trading partners.
In plain English, EPCIS helps answer:
Can the shipment data move electronically in a structured way that systems can receive, read, store, and compare?
For pharmacies, EPCIS matters because many suppliers use it to send DSCSA transaction data. EPCIS can include serialized product information that supports shipment visibility, reconciliation activity, product identifier review, and record retention.
A pharmacy does not need every staff member to understand the technical structure of an EPCIS file.
But the pharmacy should know whether EPCIS data is being received, where it is stored, and how to retrieve related records when needed.
What is EDDS?
EDDS generally refers to Enhanced Drug Distribution Security.
This is the enhanced DSCSA framework for secure, interoperable, electronic tracing at the package level.
In plain English, EDDS is about moving from older, more manual product tracing toward a more electronic, connected, package-level system.
EDDS helps answer:
Can trading partners exchange and use product tracing information electronically so the supply chain can better identify and respond to problems?
For pharmacies, EDDS matters because it raises the importance of electronic transaction data, supplier readiness, product identifier information, reconciliation activity, and the ability to retrieve records when needed.
Why these terms matter to pharmacies.
These terms are not just technical vocabulary.
They connect directly to pharmacy operations.
A pharmacy needs to know:
- Which suppliers are authorized trading partners?
- Whether transaction data is being received
- Where TI and TS are stored
- Whether EPCIS data is available from suppliers
- How missing or delayed data is documented.
- How reconciliation activity is performed
- How suspect or illegitimate product concerns are handled.
- How records are retained for six years
- How records can be retrieved when someone asks
The pharmacy does not need to become a software company.
But it does need a practical process.
Why emails, portals, and spreadsheets are not enough for most pharmacies.
Some pharmacies try to manage DSCSA records through supplier portals, email attachments, downloads, spreadsheets, and staff memory.
That may feel manageable at first.
But it can become fragile quickly.
Records can be scattered.
Supplier data can be inconsistent.
Missing information can be hard to track.
Exceptions can be handled informally.
Staff may not know where to look.
Six-year retention can become difficult.
If someone asks for proof, the pharmacy may have to rebuild the story manually.
That is not where a busy pharmacy wants to be.
