Laser marking machines are widely adopted across 3C electronics, automotive components, medical devices and other industries, with steadily‑growing market demand in the United States. To gain market access in the US, compliance with FDA radiation‑safety requirements is mandatory.
Laser marking machines fall under radiation‑emitting electronic products and are regulated by the Center for Devices and Radiological Health (CDRH), a branch of the U.S. Food and Drug Administration (FDA). All laser products sold in the United States must satisfy FDA’s laser‑product performance standards specified in Federal Regulations 21 CFR 1040.10 and 21 CFR 1040.11.
01 What is 21 CFR 1040.10?
21 CFR 1040.10 is the FDA‑issued performance standard for laser products, imposing mandatory safety rules for all laser products manufactured, imported, sold or operated within the United States.The so‑called “FDA certification” in industry parlance is strictly not a standalone certificate. Instead, it represents a compliance workflow combining product testing and establishment registration. The FDA does not issue certification certificates. Upon successful review, an Accession Number is granted, which serves as the sole legal identifier for products entering the U.S. market.Most laser marking machines are classified as Class IV, the highest‑hazard laser category. Products of this class must be fitted with complete safety hardware, including protective housings, safety interlocks, key switches and emission indicators, and go through the full compliance procedure.
02 Required Test Items for Laser Marking Machines
Per 21 CFR 1040.10, the main test items for laser marking machines are listed below:
Laser Parameter Measurements
Laser output power test: Measures output power for continuous‑wave lasers, or single‑pulse energy, pulse width and repetition rate for pulsed lasers, to determine the Accessible Emission Limit (AEL).
Laser wavelength test: Characterises the central wavelength and wavelength range for laser classification and human‑eye exposure risk assessment.
Beam divergence test: Evaluates beam divergence angle and beam spot size.
Radiation Leakage Test
Measures unintended laser radiation leakage during normal operation to ensure readings stay below FDA‑specified permissible limits.
Protective Enclosure Test
Verifies whether the housing effectively prevents human access to hazardous laser radiation, and assesses radiation‑exposure risks when housing components are removed.
Safety Interlock Test
For high‑power Class IIIb and Class IV laser equipment, validates the functionality and durability of safety‑door interlocks, emergency‑stop buttons and safety switches.
Label and Warning Marking Inspection
Nameplates and warning labels must follow FDA formatting requirements, stating laser class, warning statements, maximum output power, manufacturer name and address, production date, plus the statement “Complies with 21 CFR 1040.10”.
03 Compliance Procedure
The complete FDA compliance workflow for laser marking machines consists of five major stages:Step 1: Product Submission for TestingSubmit samples to a qualified laboratory for full‑scope testing against 21 CFR 1040.10 and obtain a Laser Radiation Safety Test Report. Provided documentation is complete and no product modifications are needed, testing normally takes 1‑2 weeks.Step 2: Appoint a U.S. AgentNon‑U.S. manufacturers are required to designate a U.S.‑based agent to receive official FDA notices and conduct communications. This is a non‑negotiable prerequisite for registration.Step 3: Compile Technical DocumentationPrepare English‑language user manuals, circuit and optical diagrams, Bill of Materials (BOM), label specimens and quality‑control documentation.Step 4: Submit FDA RegistrationFile the Laser Product Report via FDA’s electronic submission system (FURLS / eSubmitter). An Accession Number will be issued once the review passes. FDA’s official review generally takes 1‑2 weeks.Step 5: Annual Maintenance ObligationAfter market launch, manufacturers must submit an annual report to the FDA by September 1 each year, disclosing previous‑year sales volumes, manufacturing status and quality‑control records. Lapsed registration status will cause customs‑clearance and sales disruptions.
04 Frequently Asked Questions
Q1: Can an IEC 60825‑1 test report be directly accepted by the FDA?No. The United States does not formally recognise IEC 60825‑1 from the EU. While FDA Laser Notice 56 permits manufacturers to reference selected IEC clauses during testing, the FDA maintains its own classification framework and labelling requirements. Products holding only CE or IEC reports risk rejection by U.S. customs or Amazon marketplaces.Q2: Does obtaining a test report mean FDA compliance is finished?No. A test report represents only the first step. Full compliance is achieved only after establishment registration and product listing with the FDA, together with receipt of an Accession Number.Q3: What should be done if product design is modified?Supplementary reports must be submitted whenever critical parameters such as laser power, wavelength or safety devices are altered.
