What are an NRTL and an SCC-accredited body, and why do they matter for chargers?

Main answer · Wecent Editorial Team

Short answer: An NRTL is a laboratory recognized by OSHA to test and certify products to US safety standards, and an SCC-accredited certification body is recognized in Canada for electrical products. Retailers, marketplaces and buyers use their marks and listings as evidence of third-party safety testing. Check that the body’s scope covers your standard and that the certificate matches your exact model.

NRTL in the US

OSHA recognizes private organizations as Nationally Recognized Testing Laboratories. Each has a scope of test standards, and uses its own registered mark to show that a product was tested and certified to the standards. OSHA publishes a current list of NRTLs.

SCC-accredited body in Canada

The Standards Council of Canada accredits certification bodies for electrical products. The SCC states that electrical products must meet Canadian codes and standards and be certified by an SCC-accredited certification body, or inspected by an accredited inspection body. SCC publishes a document of recognized marks.

Why it matters for chargers

• Buyer confidence. A mark from an accredited body shows independent testing and often factory follow-up.
• Retail and marketplace rules. Many retailers and marketplaces ask for such certification for chargers and power banks.
• Canada. The SCC states that certification is needed for electrical products sold there.
• Insurance and liability. Certified products help your position if there is an incident.
• Customs and market surveillance. Documents help to show compliance.

Dual recognition

Some organizations are both an NRTL and an SCC-accredited body, so one certification may support both countries. Confirm what the certificate covers, rather than assuming.

What to check

1. The body’s status. Is it on the current OSHA list, or SCC accredited, for the relevant standards?
2. The scope. Does it cover the standard that applies to chargers?
3. The certificate. Does it name your company, model, ratings and factory?
4. The mark. Is it the correct mark for the country, and is it on the product as required?
5. The listing. Can you find your product in the body’s online directory?
6. Validity. Is it current, with follow-up inspections up to date?

Common mistakes

Using a mark without a certificate. A certificate for a similar model. A mark for a different country. A lapsed certificate.

Quick summary

These bodies provide third-party safety certification. Check scope, model, mark and validity for the US and Canada.
