Importing medical devices into the United States requires strict FDA compliance, and the stakes are massive. 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.
Quick Answer: 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.
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 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)
Affirmation of Compliance (AofC) Codes:
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

FDA Import Alerts and DWPE
FDA's Import Alert system represents one of the most significant enforcement tools affecting medical device imports.
Understanding Import Alerts
Purpose and Authority: Import alerts inform FDA field staff that the agency has sufficient evidence to detain products without physical examination (DWPE) based on past violations or risk factors.
Automatic Detention: Products and firms subject to import alerts face automatic detention unless importers provide convincing evidence that violations are not present and root causes have been addressed.
Types of Import Alerts:
Product-specific alerts for particular device types
Firm-specific alerts for companies with compliance histories
Country-wide alerts for systemic issues
Common Medical Device Import Alerts
Quality System Violations:
Inadequate design controls
Insufficient corrective and preventive actions
Poor manufacturing process controls
Documentation and record-keeping failures
Labeling and Misbranding:
Inadequate labeling information
False or misleading claims
Missing required warnings or contraindications
UDI compliance failures
Premarket Violations:
Marketing devices without required clearance/approval
Significant device modifications without regulatory submission
Off-label promotion and unapproved indications
Removing Products from Import Alerts
Documentation Requirements:
Evidence of corrective actions addressing root causes
Third-party audit reports or certifications
Updated quality system documentation
Demonstration of ongoing compliance monitoring
FDA Review Process:
Submission of comprehensive response package

Refusal: Formal rejection requiring export or destruction within 90 days
Common Entry Filing Errors and Prevention
Critical Filing Mistakes to 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.

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.
