Struggling to launch a private-label hair clipper line in Brazil—without engineering expertise, local certification knowledge, or proven OEM support?
Haohan Electric delivered a market-ready, INMETRO-compliant electric hair clippers solution for a São Paulo–based e-commerce brand—turning regulatory uncertainty and technical gaps into a scalable, shelf-ready product line within 14 weeks.
Client Background
- Location: São Paulo, Brazil
- Type: Direct-to-consumer (DTC) personal care brand launching its first hardware category
- Pain points:
- No in-house mechanical or electrical engineering capability
- Zero familiarity with NBR IEC 60335-2-23 safety requirements or ANATEL radio-frequency compliance
- Uncertainty around Portuguese-language labeling, IP rating validation, and dual-voltage (127V/220V) configuration for Brazilian households
- Risk-averse on first-time OEM engagement: needed full documentation traceability, pre-shipment QC reports, and warranty-backed after-sales framework
Stated Requirements
- OEM private branding with localized packaging—including INMETRO ID placement, Selo Verde recycling symbol, and mandatory Portuguese safety warnings
- Minimum viable order volume compatible with initial marketplace launch (not mass retail)
- Full regulatory hand-holding: certification application support, test report translation, and importer-facing documentation (Form A, technical dossier in PT)
- Logistics-optimized packaging: sea-freight durable cartons rated for 90-day humidity exposure, retail-ready blister + box configuration
- 12-month warranty with documented repair turnaround SLA (≤15 business days for Brazil-based returns)
Solution Delivered
Haohan executed end-to-end OEM development for professional grooming trimmers, including:
- In-stock wholesale baseline: 1,200 units shipped from existing inventory (1 full carton), enabling rapid market testing before full production

- Technical adaptation: Dual-voltage auto-sensing circuit (127V–220V), stainless steel self-sharpening blades (HRC 62), 90-minute runtime (3000 mAh Li-ion), noise level ≤58 dB(A)
- Documentation package: Portuguese user manual, INMETRO certificate, non-privileged origin certificate, and SISCOMEX-compatible packing list
Product Technical Specifications
- Motor type: Precision-core rotary motor (10,000 RPM no-load)

Commercial Outcomes
- Time-to-market reduced by 40% vs. client’s internal estimate (14 weeks from inquiry to FBA warehouse receipt)
- First-batch sell-through rate: 92% on Amazon BR within 30 days
- INMETRO certification secured in 22 working days (vs. industry average of 45+ days)

Frequently Asked Questions
What is the minimum order quantity for in-stock wholesale of electric hair clippers?
We supply electric hair clippers from existing inventory with a minimum order of 1 full carton — no customization required. Carton quantities vary by model (typically 12–24 units), and all units ship with standard Haohan branding, CE/ROHS certification, and 12-month warranty coverage.
Can you produce Brazil-certified hair trimmers with INMETRO marking and Portuguese labeling?
Yes. We manufacture Brazil-certified hair trimmers to NBR IEC 60335-2-23, embed INMETRO ID directly into product and packaging, and supply fully compliant Portuguese-language labeling, user manuals, and Selo Verde recycling symbols. Certification documentation is delivered pre-shipment.
Do you support OEM development for professional grooming trimmers with custom blade systems or motor specs?
We engineer professional grooming trimmers to your technical specifications: SK-5 or ceramic-coated blades, adjustable taper levers, precision-core rotary motors (up to 10,000 RPM), and IPX4-rated housings. Full BOM, PCB schematics, and test reports are shared before tooling approval.
What voltage configurations do you offer for barber-grade clippers targeting Latin American markets?
All barber-grade clippers for LATAM include auto-sensing dual-voltage circuitry (127V/220V). We validate performance at both voltages and supply INMETRO- and ANATEL-compliant power adapters or USB-C input modules — no re-engineering required for regional rollout.
How do you ensure consistency across production batches of OEM hair cutting tools?
We enforce batch traceability using ERP-linked QC checkpoints: raw material lot tracking, SMT stencil validation, 100% functional testing per unit, and AQL Level II inspection (Critical 0.0, Major 1.0). Third-party SGS pre-shipment reports are included at no extra cost.
