FCC certification is a U.S. radio communication standard and is a compulsory certification system.
The FCC has jurisdiction over private-sector communications and regulates disruptive electromagnetic waves (EMIs) from major electrical and electronic products for efficient use and management of radio resources, which are subject to strong federal telecommunications law.
Therefore, obtaining FCC certification is essential to sell products in the United States, as it is impossible to land products in the United States without FCC certification of related products.

Information equipment such as wireless devices, computers, peripherals, etc., wireless telephones, industrial/scientific/medical high-frequency devices, broadcasting receivers, equipment connected to PSTN (telephone, fax, modem, ADSL, etc.).

UL marks attached to most products that are intended to be exported to the United States are regulated to minimize user personal injury, human life and property damage and are arbitrary rather than compulsory. However, the reliability of UL in the U.S. is highly regarded and is highly favored by consumers, requiring most producers, sellers, and importers, which is actually a mandatory requirement to export to the U.S.

17,000 types of items, including electrical/electronic products, building structures, building materials, fire protection products, pool equipment, toy flammable liquid storage, hazardous materials, safety-related software, and ship products, accounting for 70% of the total electricity sector.

The energy efficiency certification program is designed to encourage the use of energy-saving products to reduce carbon dioxide emissions and pollutants caused by inefficient energy use. Products that have obtained energy star are products that meet strict energy efficiency guidelines and can reduce energy costs. In the U.S., it is self-certified because of the benefits of tax reduction when purchasing energy star products, but it is essential for companies to establish sales strategies.

Energy efficiency labels are applied to eight categories of electrical and electronic products, building structures, building materials, heating and cooling machines, and batteries, and are being added continuously.

DLC is a product certification through scheduling tests to ensure the high quality and high performance of lighting systems.
Energy Rebate Program with Energy Star is a North American energy saving product certification system, which is not usually compulsory for the sale of lighting in the United States, but is essential to establishing a sales strategy for companies as consumers can receive a price discount under the rebate program.

The FDA is classified into three categories, first, second and third, depending on the risk of medical devices, and generally the lowest-risk first-class medical devices are registered with the FDA, with more than 90% requiring U.S. FDA clearance (510K) for second-class medical devices. Class 3 medical devices must be FDA-approved (PMA) before being sold to the U.S. market.

In the United States, medical devices are defined in Section 201(h) of the FD&C Act, and medical devices in the United States are treated as medical devices, in some cases accessories and components, as well as finished products.

NRTL means a Nationalally Recognized Testing Laboratory recognized by the Occupational Safety and Health Administration (OSHA) under the U.S. Department of Labor. OSHA specified safety standards in Code of Federal Regulations (CFR) 29, and NRTL certification provisions in 29 CFR Part 1910. Under U.S. law, OSHA designates private testing laboratories in the U.S. as NRTL, forcing certain industrial products (37 fields) to receive product testing and certification from NRTL.

(1) Fire prevention and fire extinguishing equipment: automatic sprinkler system, fire extinguisher (dry chemicals, spray foam, gas-based drugs, etc.), fire extinguisher, portable fire extinguisher, fire alarm system, fire door, heat detection device, flame arrester, hose, etc.
(2) Gas equipment: LPG-related equipment, LPGhandling equipment, and machinery, such as LPG storage, valves, pipes, etc.
(3) Products used in hazardous environments at risk of explosion (explosion proof products)
(4) Electrical and electronic products

In order to import telecommunication devices to Mexico, they must obtain final approval from IFETEL after being tested at a designated laboratory and certified by a Mexican designated certification authority. Since laboratories and certification institutions are designated according to the specifications applied to telecommunication products, they must be checked according to the items requested, and the certification mark of the certification institution shall be affixed after obtaining the certification.

The Mexican Standard (NOM) is a product quality and safety defect that must be equipped with products that can harm the environment, public health and consumer safety so that only formal inspections of products that meet certain specifications, safety requirements, labeling requirements, quality testing, packaging, etc.
It is a system. It must be issued by a designated certification authority from a Mexican accreditation agency, and products that fall under compulsory regulation must be marked on the product after NOM certification for customs clearance and sale.

The Canadian government requires companies to maintain a certain level of performance and safety for products and services sold in Korea, and stricter regulations apply, especially to companies that install power lines, electrical equipment, and devices that are at high risk of electric shock. In order to sell a product to Canada, it is necessary to obtain a designated certification that can prove the performance and safety of the product, and the most preferred certification is CSA certification.

Forced items: electrical appliances, electrical machinery, electrical currents, electrical components, materials and gas/oil combustion appliances
Other items: HVAC (heat, ventilation and air conditioning) systems and components, power control and switchover of home entertainment products, plumbing products, leisure vehicles, process control, exercise and personal protective equipment, building supplies, energy, environment, etc.

IC certification is controlled by Industry Canada (IC).
It is a compulsory certification system for telecommunication devices. IC is a Canadian telecommunication standard that oversees telecommunication standards as well as EM standards, and IC regulations are similar to FCCs in the United States as they are in Korea to protect life and property safety in radio waves and other communication environments. Most electrical/electronic devices, including telecommunication devices and PCs, must obtain IC approval to export to Canada.

Type approved devices (1 boilers): wired devices, wireless devices
Type-approved non-targeted equipment (2-type equipment): Equipment subject to electromagnetic wave testing
