Importing medical devices into the United States requires strict FDA compliance, and the stakes are massive. Medical device importers must ensure premarket compliance (510(k)/PMA), establishment registration and listing, proper CBP filing codes (DEV, LST, PM#), and ongoing MDR obligations. Foreign manufacturers need US agents while initial importers must maintain complaint files in the US. Products that don't meet requirements face detention, refusal, and destruction, often costing importers hundreds of thousands in lost inventory. With FDA's PREDICT system automatically screening every entry, understanding import requirements is critical.
This guide covers all FDA import requirements and compliance strategies to prevent detention and refusal.
FDA Import Authority and Enforcement Overview
The FDA's Office of Import Operations protects consumers by ensuring that medical devices offered for import into the US meet all regulatory requirements under the Federal Food, Drug, and Cosmetic Act (FD&C Act).
FDA-CBP Collaboration
FDA Electronic Review Process
PREDICT Risk Scoring System: FDA uses the PREDICT system to score import entries based on compliance history and data quality. Complete, accurate data reduces the likelihood of holds and examinations.
Required CBP/ACE Filing Elements: Customs brokers must file specific FDA data elements through CBP's Automated Commercial Environment (ACE):
Mandatory Program and Data Codes:
- Program Code DEV for medical devices
- FDA Product Code matching device classification
- HTS Code (Harmonized Tariff Schedule)
- Intended Use Code (IUC) is mandatory for medical devices (unless disclaimed)
- LST (device listing confirmation)
- PM# (510(k) premarket notification number)
- IDE (investigational device exemption)
- DEV (device foreign manufacturer)
- DFE (device foreign exporter registration number)
- KIT (convenience kit confirmation when applicable)
Data Hygiene Best Practices:
- Use consistent manufacturer and shipper names across all documentation
- Ensure DEV/DFE codes match device listing (LST) information
- Always transmit PM#/PMA numbers when product codes require premarket authorization
- Verify all FDA numbers are current and accurate before transmission
Risk-Based Selection: FDA uses risk-based criteria to select entries for enhanced review or physical examination, considering factors like:
- PREDICT scoring based on compliance history and data accuracy
- Device classification and risk level
- Country of origin and manufacturer compliance history
- Import alert status and previous violations

Common Entry Filing Errors and Prevention
Critical Filing Mistakesto Avoid
LST/DEV/DFE Number Errors:
- Use the right AofC for the right entity. Send LST for device listing, DEV for the foreign manufacturer registration, DFE for the foreign exporter registration.
- Make sure each number exists, matches the firm on the line, and matches the LST.
Missing Premarket Authorization Numbers:
- If your product code requires premarket authorization, transmit PM# with the correct qualifier (K, P, or DEN)
- Verify the requirement in the Product Classification Database and make sure the PM# matches the LST
Product Code Misclassification:
- Choose the current FDA product code that matches intended use and technology
- Confirm via the Product Classification Database and the Product Code Builder
- If the LST and product code do not match, fix the mismatch before you file
Special Considerations for Different Device Types
Different medical device categories have unique import considerations and requirements.
Software and Digital Health Devices
Medical Device Data Systems (MDDS): Most MDDS/image storage/communications remain devices, but FDA generally does not intend to enforce device requirements for these low-risk functions (enforcement discretion). Some software functions are non-device under the Cures Act—separate from MDDS.
Software as a Medical Device (SaMD):
- Classification depends on risk level and intended use
- May require 510(k) clearance or De Novo authorization
- Cybersecurity considerations for connected devices
- Version control and update management requirements
In Vitro Diagnostic Devices (IVDs)
Special Labeling Requirements: IVDs have specific labeling requirements under 21 CFR Part 809 including intended use statements, performance characteristics, and limitations.
CLIA Considerations: Clinical Laboratory Improvement Amendments (CLIA) requirements may affect IVD import and distribution depending on intended use environment.
Emergency Use Authorizations: During an emergency, EUA-authorized IVDs may be imported under EUA conditions; verify current status/transition plan—standard ACE screening still applies.
Radiation-Emitting Electronic Products
Dual Regulation: Products that emit radiation and function as medical devices must comply with both medical device requirements and radiation safety requirements.
Performance Standards:
- Compliance with applicable radiation performance standards
- Radiation safety labeling requirements
- Product report submissions to FDA
Declaration Requirements: Importers must submit Declaration of Products Subject to Radiation Control Standards (Form FDA 2877) for applicable products.
Post-Import Compliance Obligations
Import compliance doesn't end when products clear customs. Ongoing obligations ensure continued regulatory compliance throughout product lifecycle.
Medical Device Reporting (MDR)
Mandatory Reporting Requirements:
- Importers and manufacturers must submit reportable deaths or serious injuries to FDA within 30 calendar days of awareness
- Manufacturers also submit 5-day reports when remedial action is needed to prevent an unreasonable risk to public health
- User facilities report deaths/serious injuries within 10 work days
- All manufacturer/importer MDRs are filed electronically (eMDR) via ESG (web eSubmitter or AS2/HL7)
- Maintain MDR procedures and MDR event files for ≥2 years or the device lifetime, whichever is longer.
Initial Importer Specific Obligations: Initial importers must maintain complaint files accessible in the United States and have specific MDR reporting responsibilities under 21 CFR Part 803.
Coordination Requirements: Initial importers must coordinate with foreign manufacturers for comprehensive investigation and reporting of adverse events.

Common Import Compliance Mistakes to Avoid
Documentation and Classification Errors
Incorrect HTS Codes: Using wrong Harmonized Tariff Schedule codes can trigger incorrect FDA review pathways and potential delays or violations.
Incomplete FDA Documentation: Missing required FDA data elements in import entries leads to holds and additional review requirements.
Misclassification of Importer Role: Incorrectly identifying as initial importer versus distributor affects compliance obligations and FDA expectations.
Regulatory Status Misconceptions
Assuming CE Mark Equals FDA Compliance: European CE marking doesn't satisfy FDA requirements; separate US regulatory authorization is required.
Misunderstanding Exemption Status: Incorrectly assuming device exemptions apply can result in marketing uncleared devices and significant violations.
Ignoring Device Modifications: Changes to cleared devices may require new regulatory submissions before import and distribution.
Operational Compliance Gaps
Inadequate US Agent Arrangements: Foreign manufacturers often underestimate US agent responsibilities and fail to maintain proper relationships.
Poor Import Alert Monitoring: Failing to monitor import alert status leads to unexpected detentions and compliance issues.
Insufficient Emergency Response: Lack of preparation for detention, refusal, or FDA examination scenarios causes unnecessary delays and costs.
