DSCSA Compliance Built Into Every Transaction

Every transaction on InStockRx includes DSCSA documentation — automatically generated, stored, and accessible. This ensures compliance and peace of mind.

DSCSA + T3 Documentation

Verified Authorized Trading Partners

GS1 Certified

Only US P2P Marketplace

Transparency and Traceability You Can Trust. Guaranteed on Every Transaction.

The Drug Supply Chain Security Act (DSCSA) requires pharmacies to maintain strict control over how they buy and sell medications. Many platforms claim compliance but InStockRx provides the same kind of T3 data with every transaction that you get from your wholesaler.

InStockRx ensures every buyer and seller receives the documentation required to remain compliant.

What Does DSCSA Require, and How Does InStockRx Deliver It?

DSCSA Requirements for Pharmacies Explained in Plain Language

New to DSCSA terminology? See our plain-English DSCSA glossary for definitions of T3, TI, TH, TS, ATP, and more. Or review the DSCSA compliance checklist for pharmacies.

The DSCSA mandates that pharmacies only buy and sell with Authorized Trading Partners (ATPs) and maintain complete documentation of every transaction. InStockRx provides all three required T3 components automatically:

1.

Transaction Information

(TI)

Includes:

  • Product name
  • Strength and dosage form
  • NDC (National Drug Code)
  • Container size
  • Lot number
  • Transaction date
  • Shipment date
  • Transfer type

How InStockRx helps:

You never manually collect TI. It's attached to every listing and every sale.

2.

Transaction History

(TH)

The chain-of-custody record.

  • Chain of custody documentation
  • Full serialization information
  • Date of each transaction
  • Traceability to manufacturer
  • Verification of authenticity

How InStockRx helps:

TH is automatically compiled and securely stored so you're always inspection-ready.

3.

Transaction Statement

(TS)

A legal attestation.

  • Seller is authorized trading partner
  • Product received was legitimate
  • Transaction information is accurate
  • No reason to believe product is illegitimate
  • Systems and processes are in place

How InStockRx helps:

We generate, verify, and store the TS for every transaction, protecting buyer and seller.

Every Pharmacy on InStockRx Is Fully Verified

Before any pharmacy can buy or sell on InStockRx, they go through our full verification process. Every participant is confirmed as a licensed, authorized trading partner under DSCSA — no exceptions. You never have to vet a seller yourself. We've already done it.

Fully Licensed

Every pharmacy on the platform holds an active, valid state pharmacy license. Unlicensed participants cannot join.

DSCSA Authorized Trading Partner

Every member is verified as an ATP under DSCSA before their first transaction. This status is confirmed, not assumed.

No Unverified Access

No pharmacy can list, browse, or complete a transaction until verification is complete. The marketplace is closed to everyone else.

What this means for you as a buyer

Every seller you trade with on InStockRx has already been verified as a licensed, DSCSA-compliant authorized trading partner. You can transact with confidence knowing your compliance is protected on both sides of every deal — without doing any of the legwork yourself.

No medication can be bought or sold on InStockRx without these safeguards in place.

Enterprise-Level Security for Regulatory Data

InStockRx protects sensitive data using:

End-to-end encrypted documentation storage

Multi-layer access controls

Continuous security monitoring

Redundant cloud backups

Role-based permissions for pharmacy teams

Your compliance documents stay secure, private, and accessible for years.

Industry First

GS1 Certified — The Only US Pharmacy-to-Pharmacy Marketplace With This Credential

GS1 is the global standard that powers drug serialization, barcode identification, and supply chain traceability. DSCSA is built on GS1. InStockRx is built on GS1. No other US P2P pharmacy marketplace has publicly confirmed this certification.

What is GS1?

GS1 is the international nonprofit that defines the barcodes, serial numbers, and electronic data interchange formats used throughout pharmaceutical supply chains worldwide. Every prescription drug in the US is identified using GS1 standards — from manufacturer to wholesaler to pharmacy. The FDA's DSCSA traceability requirements are built entirely on GS1 identifiers and data standards.

Why does GS1 certification matter for a marketplace?

A GS1-certified marketplace validates drug identification data against globally recognized standards — not custom formats that may diverge from regulatory requirements. It means every NDC, lot number, and serial identifier on InStockRx is verified against the same standards your wholesaler uses. Your T3 documentation speaks the exact language the FDA requires, making audits faster and compliance airtight.

Why Does DSCSA Matter More Now Than Ever?

Strengthened Enforcement Means Higher Risk for Non-Compliant Pharmacies

DSCSA enforcement has increased dramatically, and pharmacies are now expected to:

  • Maintain accurate product traceability
  • Prove authorized trading partner status
  • Produce T3 documents immediately
  • Track movement at the package level
  • Prevent diversion or counterfeit introduction

Non-compliance can lead to:

  • • FDA warning letters
  • • Significant fines
  • • License suspension
  • • Criminal penalties
  • • Reputational damage

InStockRx is the only platform built with full T3 automation as default, protecting your pharmacy from these risks.

Common DSCSA Questions

What is DSCSA T3 documentation?

DSCSA T3 documentation refers to the three records required by the Drug Supply Chain Security Act for every medication transaction: Transaction Information (product name, strength, dosage form, NDC, lot number, expiration date, quantity, transaction date), Transaction History (the complete chain of custody), and Transaction Statement (a statement that the seller is authorized and the product is not known to be counterfeit). These documents must accompany every sale or transfer of prescription medications.

Does InStockRx provide DSCSA T3 documentation automatically?

Yes. Every transaction on InStockRx includes automatically generated, stored, and accessible DSCSA T3 documentation. InStockRx provides the same kind of T3 data with every transaction that you receive from your wholesaler — ensuring compliance without any additional paperwork on your part.

How does InStockRx verify that pharmacies are authorized trading partners?

Every pharmacy on InStockRx is fully verified before they can buy or sell. Every participant must be confirmed as a licensed, authorized trading partner under DSCSA before their first transaction. This means you can trade with confidence knowing every counterparty is a legitimate, licensed pharmacy — no exceptions.

What are the consequences of DSCSA non-compliance?

Non-compliance with DSCSA can result in FDA warning letters, significant fines, license suspension, criminal penalties, and serious reputational damage. Enforcement has increased dramatically in recent years, and pharmacies are now expected to maintain accurate product traceability, prove authorized trading partner status, produce T3 documents on demand, and track movement at the package level.

Is pharmacy-to-pharmacy trading on InStockRx DSCSA compliant?

Yes. InStockRx is built specifically for DSCSA compliance. The platform handles Transaction Information, Transaction History, and Transaction Statement documentation for every buy and sell transaction automatically. InStockRx also ensures secure data retention and audit access so you can produce compliance records whenever needed.

Can independent pharmacies legally buy and sell medications to each other?

Yes. Licensed pharmacies can legally transfer prescription medications to one another as long as the transaction includes the required DSCSA documentation: Transaction Information, Transaction History, and Transaction Statement. InStockRx is a peer-to-peer marketplace built around this legal framework. Every seller is a verified, licensed pharmacy, and every transaction automatically generates the complete T3 package so both parties stay compliant.

What does a DSCSA compliant pharmacy marketplace look like?

A DSCSA compliant pharmacy marketplace verifies that every participant is a licensed, authorized trading partner, generates T3 documentation (TI, TH, TS) automatically for every transaction, stores compliance records with audit-ready access, and tracks product at the package level. InStockRx does all of this for every buy and sell. You get the same compliance documentation you would from a traditional wholesaler, with the flexibility of trading directly with other pharmacies.

How do I know if a pharmacy I'm buying from on InStockRx is legitimate?

Every pharmacy on InStockRx goes through a full verification process before they can list, browse, or purchase. Each participant must be confirmed as a licensed, authorized trading partner under DSCSA before their first transaction. If a pharmacy does not pass verification, they cannot participate in the marketplace — no exceptions.

What does it mean that InStockRx is GS1 certified?

GS1 is the international standards organization that defines the barcodes, serial numbers, and data formats used throughout pharmaceutical supply chains worldwide. DSCSA compliance is built on GS1 standards — every drug serial number, lot identifier, and EPCIS event format the FDA requires traces back to GS1. Being GS1 certified means InStockRx's platform uses verified, standardized drug identification data — the same format your wholesaler uses and the same format the FDA requires for traceability. InStockRx is the only US pharmacy-to-pharmacy marketplace with GS1 certification. No other US P2P marketplace has publicly confirmed this credential.
