| Shipping | Sea freight saves 60% vs. air for bulk orders |
| MOQ | Typically 50-100 units for custom orders |
Tip: Request samples with material test reports before large purchases.
Types of Power Shears
Three main categories dominate the market:
- Electric Shears - Corded (500W-2000W) for workshops
- Pneumatic Shears - Air-powered for hazardous environments
- Cordless Shears - 18V-36V battery models for job sites
Recent data shows electric models account for 68% of global sales due to lower operating costs.
