If you import electrical, electronic or mechanical equipment from China to the US or Canada, you may find this article of interest: ‘What Products Need CSA or ETL Certification? A Quick Guide for North American Importers’. Below is a concise overview of which product categories require certification – and which standards apply.
Quick Answer: What Needs Certification?
In short: anything that plugs into a wall outlet, runs on electricity, or could cause a safety hazard needs CSA or ETL certification for North American market access. This includes:
- Household appliances (kitchen, laundry, personal care)
- Lighting products (fixed, portable, LED, outdoor)
- Power tools and outdoor equipment
- HVAC and refrigeration equipment
- Industrial machinery and control panels
- Wire, cable, and connectors
- Transformers, power supplies, and adapters
- Energy storage and renewable energy equipment
- EV charging equipment

9 Product Categories — With Applicable Standards
1. Household Appliances
Examples: Coffee makers, blenders, toasters, washing machines, refrigerators, microwave ovens, hair dryers, space heaters. If it's sold at Walmart, Home Depot, or Amazon — it needs certification.
Key Standards: UL 60335-1, CSA C22.2 No. 60335-1, and product-specific sub-standards (UL 60335-2-24 for refrigerators, UL 60335-2-25 for microwaves, etc.)

CSA vs. ETL: Which One Do You Need?
Both CSA and ETL are NRTL marks recognized by OSHA — they're legally equivalent in both the US and Canada. The choice comes down to your target market and product type:
| Factor | CSA Certification | ETL Certification |
|---|---|---|
| Issuing Body | CSA Group (Canadian) | Intertek (Global) |
| Best For | Products sold primarily in Canada | Products sold primarily in the US |
| Retailer Preference | Preferred by Canadian retailers (Canadian Tire, RONA) | Widely accepted by US retailers (Walmart, Home Depot, Lowe's, Amazon) |
| Typical Timeline | 6–8 weeks | 4–6 weeks |
| Cost Range | $8,000–$20,000 USD | $5,000–$15,000 USD |
| Factory Inspection | Required | Required |

What About Small Batches or Custom Equipment?
If you're importing a limited quantity of custom machinery or specialized equipment, standard certification may be overkill. Two lighter alternatives exist:
- CSA Special Inspection (SI) — One-time field evaluation for limited-production or custom equipment. No ongoing factory inspection required. Ideal for 1–50 units.
- ETL Limited Production Certification (LPC) — Similar to CSA SI but under the Intertek system. No follow-up factory inspections. Good for small production runs.
