Regulatory entities and regulatory basis
The FDA compliance of laser marking machines is managed by the CDRH Center for Devices and Radiological Health, a subsidiary of the FDA. The core regulation is 21 CFR 1040.10, with some special scenarios referring to 21 CFR 1040.11. At the same time, it is accompanied by 21 CFR 1002 report and 21 CFR 1010 label related provisions. It belongs to mandatory compliance for radiation electronic products, not medical device registration. As long as it is imported, sold, and circulated in the United States, it needs to be done. Note that IEC 60825 can only be used as a testing reference and cannot directly replace this set of US regulations.
Authentication Mode Description
Many people may misunderstand it as a certification type certification. CDRH laser products are self declared by the manufacturer and submitted for filing, and the FDA does not pre audit the certification. The enterprise completes the testing and proves that the product meets the standards on its own, submits the materials for filing to the FDA, and obtains the Accession number, which is the compliance certificate without a paper certificate. It must be completed before the product is launched, otherwise the customs will detain and return the goods, and may also impose fines.
FDA laser classification (common categories of laser marking machines)
According to the achievable emission limit AEL classification, most industrial fiber optic and CO ₂ laser marking machines belong to Class 3B or Class 4, with the highest risk and the strictest requirements for safety devices, testing, and labeling.
-Class I: Normal use without exposed laser radiation
-Class II: Low power visible light laser
-Class IIIa: Low to medium power, short-term risk of direct viewing
-Class IIIb: Medium power, direct exposure can harm the eyes
-Class IV: High power, eye and skin burns, fire risk, the vast majority of industrial marking machines fall under this category
Mandatory Radiation Safety Testing Projects
The purpose of the test is to verify that the laser radiation of the entire machine does not exceed the corresponding level of AEL limit under foreseeable operating conditions. Mainly includes: reachable laser radiation measurement, multi pulse exposure assessment, safety interlock function verification, key switch/emergency stop function testing, shell protection light leakage testing, and radiation overflow testing under temperature control failure.
Mandatory requirements for hardware security structure (Class3B/4 emphasis)
High level laser marking machine mandatory configuration: safety interlock door, open cover to cut off laser output; Key switch, power-off locking; Emergency stop button; Laser protective cover to limit exposure during normal operation; Beam termination/blocking to prevent beam leakage. After the safety components fail, the equipment cannot continue to output excessive laser.
Requirements for Product Labels and Instructions
The product body must be permanently affixed with English certification labels and laser hazard warning signs. The label should indicate the laser grade, wavelength, maximum output power, manufacturer information, and compliance statement. The user manual needs to specify laser hazards, protection requirements, maintenance precautions, and maintenance warnings. If opening the cover during maintenance will expose the laser, a separate warning must be issued.
Enterprise registration and product listing process
Two steps are indispensable:
1. Institution registration: Manufacturers register their corporate institutions with CDRH;
2. Product listing: Submit the laser marking machine model, laser medium, wavelength, power, and classification information to complete the product listing.
After submitting the technical report, obtain an Accession number for customs clearance and listing on e-commerce platforms such as Amazon.
Annual Report and Data Retention Obligations
Filing is not a one-time task. Manufacturers are required to submit annual reports to CDRH, continuously maintain product sales records, test raw data, drawings, and label versions. The relevant technical files need to be stored for a long time, and the FDA can access and verify them at any time.
Common Misconceptions
1. Obtaining a third-party testing report ≠ FDA filing completion. The report is only internal compliance evidence and needs to be submitted to CDRH along with registration and listing;
2. The export of laser modules separately is generally exempted, but if they are made into a whole machine marking machine, the whole machine must be CDRH compliant;
3. CE's laser safety cannot replace FDA, and two independent regulations cannot be mutually recognized.
