Need a dual-speed professional hair trimmer that meets U.S. market compliance—without engineering expertise on your team? Zhejiang Haohan Electric Appliance Co., Ltd. delivered a fully customized, UL- and FCC-certified custom-branded grooming device for a U.S.-based brand in just 12 weeks—from concept to production-ready units.
Client Background
- Location: United States
- Type: Early-stage personal care brand with direct-to-consumer (DTC) e-commerce operations
- Pain points:
- No in-house engineering or regulatory staff; unable to specify motor control architecture or compliance pathways
- Rejected two prior supplier proposals due to lack of U.S.-targeted certification planning (UL/FCC/CA Prop 65)
- Required physical branding integration (logo placement, color-matched housing, retail-ready packaging) but lacked injection molding or packaging design capacity
- Needed dual-speed functionality with tactile, fail-safe switching—no software dependencies or app reliance
Stated Requirements
- A professional-grade trimmer, fully customized: housing geometry, brand color scheme (Pantone 294C + matte black), logo embossing, and retail-ready blister + carton packaging
- Two user-selectable operating speeds (6,500 RPM / 8,200 RPM), controlled via mechanical slide switch (no firmware, no battery drain from logic circuits)
- U.S. market compliance: UL 60335-2-100 (household appliance safety), FCC Part 15B (EMI), ANSI Z535-compliant labeling, California Proposition 65 warnings, and “Made in China” origin marking per 19 CFR §134
Solution Delivered
Haohan executed end-to-end OEM development—including industrial design, motor & PCB architecture selection, compliance testing coordination, and full-line production—with zero handoffs to third-party labs or design houses.
- In-stock wholesale availability: 100% configurable base model (min. order: 1 full carton = 48 pcs)
- Full customization path: Achieved at 3,000 pcs MOQ—covering housing color, logo embossing depth (0.3 mm ±0.05 mm), battery capacity (1,800 mAh Li-ion), USB-C charging, and dual-voltage input (100–240 V AC adapter)
- Regulatory ownership: Haohan managed all UL listing (E517539), FCC ID (2AGXH-HT200), and Prop 65 documentation; provided final label artwork compliant with CPSC 16 CFR Part 1500

Project Outcome
- Time-to-market reduced by 37%: First production batch shipped 84 days after contract signing—vs. industry average of 132 days for first-time U.S.-compliant OEM trimmers
- Zero compliance rework: All 3,000 units passed UL factory inspection on first audit; no labeling or EMI failures
- Brand execution fidelity: Logo embossing tolerance held to ±0.03 mm across all units; Pantone-matched housing color deviation ΔE ≤ 0.8 (measured via spectrophotometer)
- Commercial impact: Client launched on Amazon US with Prime eligibility; achieved $247,000 in Q1 revenue (1,850 units sold)
Why This U.S. Brand Chose Haohan

Frequently Asked Questions
Can you supply dual-speed professional hair trimmer units without branding for immediate resale?
Yes. We maintain a certified in-stock wholesale program: 100% configurable base models ship within 48 hours of order confirmation. Minimum order is one full carton (48 pcs). All units include UL/FCC-compliant electronics, dual-winding motor, and USB-C charging—ready for private-label or white-label integration.
What lead time applies to a fully customized custom-branded grooming device at 3,000 pcs MOQ?
From signed contract to FOB shipment: 8–10 weeks. This includes industrial design finalization, mold modification (if required), compliance testing, and production. Sample delivery occurs within 7 business days of design approval—no tooling deposit required for existing platform adaptations.
Do you support regional electrical standards for an adjustable-speed barber trimmer sold across multiple markets?
Yes. We configure voltage input (100–240 V AC), plug types (EU, UK, US, AU), and battery output specifications per target market. All configurations undergo region-specific certification: UL/ETL for North America; CE + UKCA + RoHS for EEA/UK; SIRIM for Malaysia; ANATEL for Brazil.
How do you ensure consistent color and logo accuracy on a OEM dual-mode trimming tool?
We enforce strict tolerances: Pantone-matched housing color deviation ≤ ΔE 0.8 (measured pre-shipment); logo embossing depth held to 0.3 mm ±0.03 mm across all 3,000 units. Spectrophotometer reports and embossing gauge logs are provided with every batch.
Can you produce a branded two-speed precision trimmer with mechanical speed switching—and no firmware dependencies?
Yes. All dual-speed variants use a sealed IP54 mechanical slide switch—zero microcontrollers, zero firmware updates, zero battery drain from logic circuits. Switch durability is validated to 10,000+ cycles. Electrical architecture documentation, including schematic and BOM, is delivered with final samples.
