Key points of FDA certification for laser tape measures in the United States
1. Applicable regulatory basis
Laser tape measures belong to the category of laser measurement/detection products, and their exports to the United States are regulated by the
Center for Devices and Radiological Health (CDRH) under the Food and Drug Administration (FDA). The core regulations are 21 CFR 1040.10
(Performance Standards for Laser Products) and 21 CFR 1010 (Radiation Control for Electronic Products). Products that have not been registered
with the FDA cannot pass through U.S. customs and face the risk of being detained or returned.
II. Selection of testing standards
Laser tape measures can be FDA tested using one of two sets of standards:
FDA 21 CFR 1040.10: FDA's own standard, directly applicable, classifies laser products into four levels (I–IV) for management.
IEC 60825-1 + Laser Notice 56: International Electrotechnical Commission standards. If this set of reports is adopted, it must be used in coordination
with FDA Notice 56 to replace some of the requirements of 21 CFR 1040.10.
III. Classification of laser safety levels
The FDA categorizes laser products into four levels based on the potential level of harm, with laser tape measures typically falling under Class I or
Class II:
Class I: No hazard, such as lasers completely enclosed within equipment.
Class II: Low-power visible light, which poses no harm when exposed briefly, typically exemplified by laser pointers and some rangefinders.
Class IIIa/IIIb: Medium power, may cause harm to eyes or skin.
Class IV: High power, capable of causing serious injury.
Different levels correspond to different testing items, safety functions, and labeling requirements.
IV. Product Testing Requirements
Laser safety testing must be conducted by a qualified third-party laboratory, and the testing content mainly includes:
Wavelength, maximum output power, or pulse energy
Radiation dose parameters and leakage radiation control
Safety protection measures (such as protective covers, safety interlocks, button controls, etc.)
The impact of product structure, optical path design, and circuit characteristics on radiation levels
The testing cycle is generally 1-2 weeks, and it requires the preparation of 1-2 test prototypes, as well as product specifications, circuit diagrams,
optical path diagrams, and other related materials.
V. FDA Registration (Reporting) Process
After passing the inspection, the product enters the FDA registration stage, which essentially involves submitting a "Product Report" to the FDA,
rather than the commonly understood "certification":
Establishment Registration: Manufacturers complete establishment registration on the FDA official website.
Product Listing: Submit a product report, including technical information and production quality assurance information.
Accession Number: Issued after FDA approval, this number can be used for product customs clearance.
VI. Requirements for Labels and Instructions
The product body and packaging must be affixed with labels that comply with regulations:
Laser Class Label: Such as "Class II Laser Product"
Warning label: Class IIa should be labeled with "Avoid Long-Term Viewing of Direct Laser Radiation"; Class IIIa should be labeled with yellow or red
warning labels depending on the power density.
Technical parameters: maximum output power, laser medium, or emission wavelength.
Manufacturer information: name, address, manufacturing location, and manufacturing date (month and year).
Declaration of Conformity: If tested in accordance with 21 CFR 1040.10, it is marked "Complies with 21 CFR 1040.10 and 1040.11"; if tested in
accordance with IEC standards, it is marked "Complies with FDA performance standards for laser products except for conformance with IEC 60825-1
Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019."
The instruction manual must be in English and include instructions for safe use. The FDA logo is strictly prohibited from being used on any report or
product packaging, but the registration number can be printed.
VII. Maintenance obligations after registration
Annual report: Submit the annual report on sales volume, manufacturing status, and quality control status as of June 30th of the current year before
September 1st each year.
Record keeping: Keep manufacturing records and product inspection and testing records in accordance with 21 CFR 1002.30 and 1002.31.
Spot check response: The FDA adopts a regulatory model of "assigning registration numbers first and then conducting random spot checks". There is
a risk that registration numbers may be cancelled, so companies need to ensure continuous compliance.
VIII. List of required documents to be submitted
Inspection stage: product specification, inspection application form, 1-2 sets of test prototypes.
Registration stage: product category attributes, model and label location, structural component description, functional and operational characteristics,
design specifications, physical and electrical characteristics description, testing methods and procedures, quality control procedures, test records,
certification labels/warning signs/nameplates, installation and operation instructions, U.S. agent agreement, product quality declaration, etc.
IX. Common precautions
After completing FDA registration, no official certificate will be issued, and any "FDA certificate" issued by a third party is not an official FDA document.
As a measuring laser product, the laser tape measure typically does not fall under the category of medical lasers (not subject to 21 CFR 1040.11), but its
specific function needs to be confirmed to determine the applicable regulations.
The registration should be based on the manufacturer company, rather than being registered separately by brand or model.
