Understanding the DSCSA: Why It Was Needed and How It Works
The pharmaceutical supply chain is a complex global network involving manufacturers, wholesalers, repackagers, third-party logistics providers, and dispensers. Ensuring the authenticity, safety, and integrity of prescription drugs is critical to protecting patients and maintaining public trust. However, historical vulnerabilities have allowed counterfeit, stolen, or contaminated products to infiltrate the market, compromising public health and exposing weaknesses in regulatory oversight.
To address these risks, the U.S. Congress passed the Drug Quality and Security Act (DQSA) in 2013, which included the Drug Supply Chain Security Act (DSCSA) as Title II. The DSCSA introduced a nationwide system for pharmaceutical traceability, establishing a comprehensive framework for tracking and verifying prescription drugs at the package level. Its phased implementation has mandated that all trading partners — including manufacturers, wholesalers, repackagers, and dispensers — adopt enhanced product tracing, verification, and serialization requirements. These measures help prevent counterfeit or compromised medications from entering circulation, ensure more efficient recalls, and restrict supply chain access to authorized entities only.
Before the DSCSA, inconsistent state regulations and regulatory gaps left the U.S. drug distribution system vulnerable. High-profile cases, such as counterfeit Avastin infiltrating the supply chain in 2012 and stolen pharmaceuticals being illegally reintroduced into distribution channels, highlighted the urgent need for a uniform, federal-level approach to supply chain security. The DSCSA established clear, enforceable guidelines to ensure that every prescription drug can be tracked, authenticated, and traced back to its source.
With full enforcement now in effect as of November 27, 2024, all pharmaceutical trading partners must comply with enhanced serialization, interoperability, and verification mandates. For manufacturers and contract service providers, compliance is no longer just a regulatory requirement — it is essential for business continuity. Noncompliance risks product quarantines, fines, and exclusion from the regulated supply chain, making adherence to DSCSA standards an operational and strategic imperative.
Challenges Faced by Industry Stakeholders
Many companies across the pharmaceutical supply chain have struggled with compliance, and the industry is still working through key challenges:
Interoperability and data exchange issues: Transitioning from paper-based to electronic tracking systems has been more complex than anticipated, with ongoing data mismatches and system integration challenges between trading partners.
Cost and resource constraints: Implementing serialization, secure data storage, and real-time traceability solutions has placed a financial and operational burden on mid-sized manufacturers, contract development and manufacturing organizations (CDMOs), and small dispensers.
Lagging adoption by trading partners: Despite the final compliance deadline, some smaller dispensers, independent pharmacies, and non-integrated supply chain partners are still behind in fully implementing DSCSA-compliant systems.
Regulatory uncertainty and adjustments: The one-year delay in DSCSA enforcement (from 2023 to 2024) provided some breathing room, but confusion remains around data interoperability, compliance audits, and exemptions.
Clarification on exemptions: The FDA has provided guidance on small dispenser exemptions, but contract manufacturers, distributors, and repackagers still face regulatory ambiguities, requiring additional clarity and best practices for compliance.
Key Provisions and Compliance Requirements
Compliance with the DSCSA hinges on four key provisions: serialization and traceability, data interoperability, verification and product investigations, and authorized trading partner (ATP) requirements. These measures ensure that pharmaceutical products are securely tracked and authenticated throughout the supply chain, reducing the risk of counterfeit or stolen drugs entering circulation.
Serialization and Traceability
One of the most significant requirements under the DSCSA is serialization and package-level traceability, which mandates that every prescription drug package carry a Unique Product Identifier (UPI). This identifier, embedded within a 2D Data Matrix barcode, contains essential information, such as the National Drug Code (NDC), serial number, lot number, and expiration date. To enable real-time traceability, all trading partners must electronically exchange this product transaction data using Electronic Product Code Information Services (EPCIS), a GS1-standardized system.
Serialization impacts the industry at multiple levels. Manufacturers and repackagers must generate and apply UPIs to all products before distribution. Wholesalers and distributors are responsible for scanning, verifying, and securely storing serialized data before passing products along the supply chain. Finally, dispensers, including pharmacies and hospitals, must confirm product authenticity before dispensing medications to patients. By enforcing serialization, the DSCSA has significantly strengthened drug security, ensuring that each pharmaceutical product remains uniquely identifiable from production to patient use.
Data Interoperability and Electronic Recordkeeping
The DSCSA also mandates a complete transition from paper-based recordkeeping to fully electronic tracking systems, ensuring that transaction data is accessible, verifiable, and interoperable across trading partners. All entities involved in drug distribution must use EPCIS or other FDA-approved formats for serialized product data exchange, eliminating inefficient and error-prone paper documentation. The standardization of real-time data sharing and verification has further streamlined supply chain operations while enhancing security.
Despite these benefits, many industry players have faced challenges in meeting data interoperability requirements. Smaller dispensers and wholesalers have struggled to upgrade legacy IT systems, while incompatibility between enterprise resource planning (ERP) platforms and serialization systems has caused integration delays. Some supply chain participants still rely on outdated documentation methods, creating bottlenecks that slow down product movement and increase regulatory risk. Companies that lack real-time electronic recordkeeping may face compliance audits, regulatory scrutiny, or even exclusion from the legitimate pharmaceutical supply chain.
Verification and Risk-Based Product Investigation
Beyond serialization and recordkeeping, the DSCSA requires robust verification and investigation processes to detect and remove suspect or illegitimate products from the supply chain. Trading partners must have mechanisms in place to verify product identifiers and flag anomalies that may indicate fraud, diversion, or contamination. If an issue arises, companies must be able to trace affected products back through the supply chain and notify the FDA and relevant trading partners immediately.
To comply with risk-based investigation protocols, trading partners are required to conduct in-depth investigations when suspect products are identified. This includes verifying serial numbers against manufacturer databases, performing forensic testing to confirm product authenticity, and securely quarantining suspect products to prevent further distribution. Failure to properly investigate and report such issues can result in regulatory enforcement actions, product recalls, and even criminal liability in cases of negligence. Given the increasing complexity of global supply chains, manufacturers, wholesalers, and third-party logistics (3PL) providers must be equipped with efficient verification systems to prevent disruptions.
ATP Requirement
A fundamental component of DSCSA compliance is ensuring that only ATPs participate in the pharmaceutical supply chain. ATPs include manufacturers, repackagers, wholesale distributors, dispensers, and third-party logistics providers, all of whom must hold valid state and federal licenses to operate legally. Companies cannot buy, sell, or distribute prescription drugs unless all entities involved are fully DSCSA-compliant.
To meet ATP verification requirements, manufacturers and repackagers must be FDA-registered and licensed, wholesalers and 3PL providers must hold state and federal distribution licenses, and dispensers can only source medications from verified ATPs. Companies that engage with unverified or non-compliant trading partners risk severe penalties, supply chain disruptions, and increased regulatory scrutiny. Failure to verify an ATP before conducting a transaction may also result in product quarantines, significant financial losses, and potential legal consequences.
As of March 2025, compliance with ATP regulations is mandatory. All trading partners must have documented procedures for verifying ATP status before engaging in transactions to ensure compliance and maintain the integrity of the pharmaceutical supply chain.
Barriers to Implementation and Industry Readiness
The transition to serialization, data interoperability, and electronic verification has presented several challenges, particularly for smaller companies, contract manufacturers, and distributors.
Serialization Gaps and Technological Barriers
Ensuring seamless serialization integration across geographies and regulatory frameworks has been a significant challenge, as variations in serialization standards and data exchange protocols have led to compatibility issues between trading partners. Many smaller wholesalers and independent pharmacies still rely on outdated IT systems that cannot efficiently handle electronic traceability, requiring costly system upgrades or third-party integration solutions.
One of the primary technological obstacles has been data mismatches between trading partners. Discrepancies in product serial numbers, lot tracking, and transaction histories have slowed down verification processes, delaying product movement and increasing compliance risks. The adoption of EPCIS standards has also been inconsistent, leading to bottlenecks in data sharing and challenges in verifying serialized drug shipments.
The impact on the industry has been significant. Manufacturers, CDMOs, and logistics providers must continue investing in data standardization and digital tracking infrastructure to close serialization gaps. Distributors and wholesalers must verify that all trading partners can exchange EPCIS data seamlessly. Failure to properly serialize and verify products can lead to compliance audits, regulatory penalties, and product quarantines, further straining already fragile supply chains.
Exemptions and Small Dispenser Considerations
While most pharmaceutical supply chain participants are subject to DSCSA compliance, the FDA has granted certain exemptions, particularly for small dispensers. However, these exemptions have introduced regulatory uncertainty, leaving manufacturers, distributors, and contract service providers unsure of how to navigate compliance expectations.
The FDA has clarified that independent pharmacies and small healthcare providers may not be required to immediately implement full electronic traceability systems. However, these dispensers must still source medications exclusively from ATPs and be able to verify product authenticity upon request. The lack of clarity surrounding compliance expectations for exempt entities has led to hesitancy among manufacturers, CDMOs, and wholesalers, who fear that working with non-compliant dispensers could introduce legal risks or disrupt DSCSA-compliant product flows.
For contract manufacturers and wholesale distributors, the uncertain regulatory landscape has made it difficult to determine whether small dispensers' non-compliance could impact their own compliance status. Some manufacturers remain unsure of their obligations when distributing to partially exempt dispensers, while wholesalers must balance compliance mandates with the practical realities of product movement to smaller buyers.
The fragmentation of compliance across different tiers of the supply chain has also posed challenges. While large pharmaceutical companies advocate for universal serialization compliance, smaller organizations seek greater flexibility in meeting DSCSA requirements. These regulatory inconsistencies could create product flow disruptions, as manufacturers and wholesalers may hesitate to work with dispensers that lack full serialization infrastructure.
To address these risks, companies must develop internal policies for working with exempt entities while maintaining full DSCSA compliance. Manufacturers and CDMOs should seek regulatory guidance from compliance specialists to navigate uncertainties around exemptions, while wholesalers must establish clear verification procedures to reduce risk exposure when dealing with smaller dispensers.
Cost and Resource Constraints
For mid-sized and smaller pharmaceutical companies, the financial and operational burden of DSCSA compliance remains a significant barrier. Large multinational corporations have already invested heavily in serialization technology, blockchain-enabled supply chain tracking, and automated verification systems. However, smaller manufacturers, CDMOs, wholesalers, and independent pharmacies often lack the financial resources and in-house expertise to fully implement these compliance measures.
Upgrading legacy IT systems, integrating serialization platforms, and ensuring full interoperability requires a substantial financial commitment. Many smaller organizations have struggled with unexpected compliance costs, including software licenses, third-party verification services, and employee training programs. Companies that initially implemented minimal DSCSA compliance measures are now facing the challenge of scaling up to meet full enforcement.
Beyond direct compliance costs, vendor compliance issues have further complicated the transition. Many pharmaceutical companies rely on 3PLs and wholesalers for distribution and verification. If a vendor fails to meet DSCSA interoperability standards, it can jeopardize product movement, trigger regulatory scrutiny, and expose supply chain partners to compliance risks.
Given these financial and operational challenges, companies should consider incremental compliance investments, prioritizing serialization and interoperability upgrades before expanding to full data integration solutions. Contracting with regulatory consultants and compliance specialists can help reduce in-house compliance burdens, allowing companies to focus on core business operations while ensuring DSCSA readiness. Additionally, organizations should explore collaborations with serialization and track-and-trace technology providers to minimize compliance costs and streamline regulatory implementation.
What’s Next: The Future of Supply Chain Security
The full implementation of DSCSA represents a fundamental shift in how pharmaceutical supply chains operate. Now that serialization, interoperability, and product verification are mandatory, maintaining compliance is an ongoing process that requires continuous monitoring, system updates, and personnel training. Compliance is no longer just about meeting deadlines; companies must ensure long-term adherence to evolving regulatory expectations and industry best practices.
Collaboration across trading partners remains crucial, as differences in IT infrastructure, serialization platforms, and system maturity continue to create data exchange inefficiencies. The push for greater standardization in data-sharing formats, enhanced automation, and interoperability improvements will be essential to fully realizing DSCSA’s vision of a secure, transparent, and efficient supply chain.
Going forward, pharmaceutical supply chain security will require not just regulatory compliance but a broader commitment to operational excellence, digital transformation, and supply chain resilience.

While the DSCSA has provided a strong regulatory foundation, future legislative updates could further tighten security measures and expand traceability requirements. Companies must remain vigilant and adaptive, ensuring that they stay ahead of evolving regulatory trends.
Expanding serialization requirements. Future regulations could extend the DSCSA’s serialization and traceability requirements beyond prescription drugs to include over-the-counter (OTC) medications, vaccines, biologics, and high-risk pharmaceuticals. As regulatory agencies continue to prioritize drug security, broader serialization mandates may become necessary to prevent counterfeit or diverted products from entering global markets.
Mandatory integration of blockchain or AI in supply chain security. As AI-powered fraud detection and blockchain-based tracking become more prevalent, regulatory agencies may begin mandating the use of these technologies to further enhance pharmaceutical security. The FDA and other global regulators could require AI-driven compliance monitoring and blockchain-integrated traceability systems, ensuring a higher level of transparency and automation in pharmaceutical distribution.
Global harmonization of drug traceability laws. While many countries have independent pharmaceutical traceability regulations, the industry may see a shift toward greater global harmonization. Regulators worldwide could work toward a unified international standard for drug traceability, ensuring that pharmaceutical companies can seamlessly track and verify products across borders. A globally synchronized approach could reduce inefficiencies, eliminate redundancies, and improve patient safety worldwide.
