1、 Regulatory framework and jurisdiction
The FDA classifies laser welding machines as Radiation Emitting Electronic Products, rather than medical devices. Mainly controlled by Chapter 5
(Subcapter C) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) - Electronic Product Radiation Control Standards. Laser welding belongs
to industrial/commercial laser equipment and must comply with 21 CFR 1040.10 (Performance Standards for Laser Products) and 21 CFR 1040.11
(Requirements for Specific Purpose Laser Products).
2、 Core authentication path
Reporting system instead of licensing system: The FDA adopts a "Report" model for laser products instead of a "Pre Market Approval" (PMA) model.
Manufacturers or importers must submit a Product Report to the FDA 30 days before the product is launched, including product description, radiation
safety test data, label samples, and compliance statements. Sales can be made without waiting for FDA approval, but the FDA reserves the right to
conduct spot checks and enforcement actions afterwards.
3、 Classification and corresponding requirements for laser grades
Laser welding machines typically belong to Class 4 (high-power lasers,>500mW), which is the strictest category regulated by the FDA. Requirements
include: having interlocks, remote interlock connectors, beam attenuators, emission indicators, and key controlled switches. The protective cover and
shielding must comply with the achievable emission limits of 21 CFR 1040.10 (f).
4、 Labeling and Identification Standards
The product must be permanently affixed with an FDA certified label, including the words "Complies with 21 CFR Chapter I, Subcapter J", laser grade
identification (Class 4), maximum output parameters, wavelength, pulse characteristics, and hazard warnings. The user manual should be accompanied
by an English version of warning instructions and operating instructions. Missing or incorrect labels are the most common reasons for FDA seizures and
penalties.
5、 Responsibilities of importers and manufacturers
US importers must act as legal responsible persons to ensure product compliance and hold the FDA report number (Accession Number) submitted by
the manufacturer. FDA Entry Form 2877 (Electronic Product Declaration) is required for customs clearance. If the manufacturer does not have a physical
presence in the United States, they must designate a US Agent to receive FDA contact.
6、 Testing and Compliance Verification
Although there is no mandatory third-party certification, the FDA recommends testing and record keeping in accordance with IEC 60825-1. The test
report must cover radiation output stability, fault mode analysis, interlock function verification, and environmental stress testing. The FDA will verify the
original test data and quality management system during on-site inspections.
7、 Common compliance risks
Typical violations include: mislabeling the laser welding machine as Class 1-3R to avoid strict control, easily deflectable interlocking devices, lack of English
warning labels, and discrepancies between the technical parameters in the report and the actual product. The FDA may impose detention, refusal of entry,
or mandatory recall on non compliant products, and impose civil fines on those responsible.
8、 Difference from FCC certification
If the laser welding machine includes a radio frequency control module (such as wireless remote control), it needs to additionally pass FCC Part 15
electromagnetic compatibility certification. The FDA and FCC belong to different regulatory systems, with the former focusing on radiation safety and
the latter on electromagnetic interference. The two cannot be replaced by each other.
