What is UL 60335 Certification Compliance?

Abstract: UL 60335 certification compliance refers to the safety evaluation of household and similar electrical appliances conducted in accordance with the UL 60335 series standards (UL 60335-1 General Requirements + UL 60335-2-XX Particular Requirements). It proves that the product presents no risks of electric shock, fire, burns, or mechanical injuries under normal use and single-fault conditions. It serves as both a "safety passport" for North American channel access and a standard compliance requirement for listing home appliances on e-commerce platforms such as Amazon and Temu.

What Exactly is UL 60335 Compliance?

UL 60335 is a series of safety standards for household electrical appliances published by Underwriters Laboratories (UL) in the United States, based on the localized adaptation of the international standard iec 60335.

It is not a single certificate title, but a standard family:

UL 60335-1: General Requirements for Safety of Household and Similar Electrical Appliances

UL 60335-2-XX: Particular Requirements for Specific Product Categories (such as kitchen appliances, fans, heaters, refrigeration equipment, battery-operated tools, etc.)

The term "UL 60335 Compliance" typically refers to two implementation forms:

Which Products are Covered by UL 60335?

Applicable Product Scope

Household Appliances: Rice cookers, air fryers, coffee makers, washing machines, ovens, vacuum cleaners, electric fans.

Similar Appliances: Equipment used in shops, farms, light industrial locations, or operated by non-professionals.

Power Supply Types: AC 120V/240V, DC, battery-powered, and dual-power products.

Examples of Typical Sub-standards:

UL 60335-2-14: Blenders, food processors, juicers

UL 60335-2-24: Refrigeration appliances

UL 60335-2-3: Electric irons

UL 60335-2-96: Power tools with thermal management lithium batteries

Excluded Product Scope

1.Pure IT / Audio and Video equipment (covered by ul 62368-1)

2.Medical electrical equipment (covered by UL/iec 60601)

3.Professional industrial equipment and automotive-grade appliances

Differences Between UL 60335 and IEC 60335

UL 60335 Test Items

Electrical Safety

1.Dielectric voltage withstand test

2.Leakage current test

4.Electrical clearance and creepage distance

5.Power input and overload testing

Thermal and Fire Safety

1.Temperature rise testing (motors, enclosures, internal wiring)

2.Thermostat failure simulation

3.Glow wire / Needle flame / UL94 flammance testing

4.Abnormal operation: locked-rotor, short circuit, fan failure

Mechanical and Structural Safety

1.Protection against access to live parts (probe testing)

2.Protection against moving parts (blades, gears)

3.Enclosure strength, drop test, stability test

4.Lid interlocks and emergency stop protection

Environmental and Operational Safety

1.Humidity pre-conditioning

2.Overflow / Spillage / Water spray testing

3.Battery overcharge, short circuit, thermal runaway (for lithium battery products)

4.Nameplate durability and manual warning statements

Why Must You Comply with UL 60335 to Export to North America?

Strict E-commerce Platform Requirements

Platforms like Amazon US, Amazon Canada, and Temu North America frequently require small home appliances to meet the following:

1.Issued by an ISO/IEC 17025 accredited laboratory

2.The report must explicitly list both UL 60335-1 + UL 60335-2-XX

3.Model, brand, and ASIN details must match exactly

4.No report  Listing removal and inventory freeze

Channel and Procurement Entry Barriers

Offline retailers such as Walmart, Home Depot, and Costco strongly prefer:

1.Formal UL Listed Certification

2.Verifiable UL Listing Control Number on the official website

3.Continuous Factory Follow-up Services (FUS)

Insurance and Liability Mitigation

Product liability litigation costs in North America are high. UL compliance significantly reduces legal and financial risks following fire or electric shock incidents.

UL 60335 Test Report  UL certification

Warning: Many manufacturers mistake a "Test Report" for a formal "UL Certificate" and print the UL mark on packaging, resulting in platform suspension due to trademark infringement.

Correct Understanding:

1.Test Report: Issued by testing laboratories for e-commerce compliance audits. Cannot print the UL Mark.

2.UL Listed: Issued directly by UL after factory audits and ongoing surveillance. Authorized to print the UL Mark.

3.ETL / cTUVus: Equivalent NRTL certifications that are widely accepted in the market. UL is not the only option.

Correct Compliance Wording:

"This product is tested to UL 60335-1 / UL 60335-2-XX"

Do NOT write: "ul certified" (unless you have achieved official UL Listing status).

Application Process

Option A: E-Commerce Platform Listing Report (Fast Track)

1.Confirm standard combination (UL 60335-1 + UL 60335-2-XX).

2.Submit documentation: BOM, schematic diagram, manual, nameplate rating label, and samples.

3.JJR Laboratory Testing (typically takes 5–15 working days).

4.Issue ISO 17025 report in Chinese and English.

5.Upload to platforms for audit.

Option B: Complete UL Listed Certification (Rigorous Track)

1.Early-stage standard assessment and gap analysis.

2.Sample submission, testing, and modification/rectification.

3.Initial Plant Inspection (IPI).

4.Certificate issuance + UL Mark authorization.

5.Quarterly Follow-Up Services (FUS) factory audits.

Frequently Asked Questions (FAQ)

Is UL 60335 certification mandatory?

A: While it may not be legally mandatory at the U.S. federal level, the National Electrical Code (NEC), major retailers, e-commerce platforms, and insurance companies virtually treat it as a mandatory requirement for market access.

Can products be sold in the US with only a test report?

A: Yes for cross-border e-commerce. However, brick-and-mortar retail stores and major enterprise clients usually demand UL Listed status or an equivalent NRTL certification.

How long is the test report valid?

A: As long as the standards and product design remain unchanged, the report remains valid long-term. If the product structure, critical components, or standards are updated, re-testing or supplementary evaluation is required.

Can an IEC 60335 report be directly converted into a ul report?

A: No, it cannot be converted automatically. Supplementary testing for North American differences (such as voltage, plugs, fire resistance, and labeling) must be performed.

Which is better, UL or ETL?

A: Both hold equal legal standing as NRTLs (Nationally Recognized Testing Laboratories). UL has higher global brand recognition, whereas ETL offers more flexible timelines and testing costs.
