Need a high-speed electric razor engineered specifically for the Brazilian market — with INMETRO certification, dual-voltage compatibility, and full local compliance — but lack in-house technical expertise to define specifications or navigate regulatory pathways?
Brazilian Brand Launches Cordless High-RPM Shaver with Haohan’s End-to-End OEM Support
A São Paulo–based DTC personal care brand sought to enter the growing Brazilian men’s grooming segment with a premium high-speed electric razor. With no prior experience in electric shaver development, the team faced critical gaps: unfamiliarity with motor performance trade-offs under tropical humidity, uncertainty around Brazilian-market shaver voltage architecture (127V/220V), and zero internal capacity to manage INMETRO-certified shaver documentation or Portuguese-language labeling.
Client Background
- Location: São Paulo, Brazil
- Type: Direct-to-consumer (DTC) startup specializing in localized grooming solutions
- Pain points:
- No engineering team to specify motor RPM, blade geometry, or thermal management for high-humidity operation
- Zero knowledge of NBR IEC 60335-2-8 test protocols or INMETRO-approved lab requirements
- Unaware of mandatory Portuguese-language labeling rules, including ANVISA-aligned hygiene claims and importer CNPJ placement
- No logistics strategy for FBA-compatible packaging or tariff classification (NCM 8510.20.00)
Stated Requirements
- Develop a cordless, high-RPM foil shaver optimized for coarse, curly Brazilian facial hair
- Support both 127V and 220V input via auto-sensing circuitry — not dual-plug adapters
- Integrate Type N (NBR 14136) plug standard with 10A rating and reinforced strain relief
- Pass INMETRO certification within 8 weeks of prototype sign-off
- Deliver fully compliant Portuguese-language packaging, user manual, and safety labeling
- Enable scalable production from 5,000 units (initial launch) to 50,000+ annually
Solution Delivered
Haohan executed a full turnkey OEM project — from motor selection and PCB layout to INMETRO lab coordination and customs-ready packaging. Key deliverables included:
- Custom-developed 12,000 RPM brushless DC motor with IPX7-rated housing and copper-coated blades for corrosion resistance in high-humidity environments
- Auto-voltage switching circuit (100–240V AC input) + 2,200 mAh Li-ion battery delivering 75 minutes runtime at full speed
- INMETRO certification secured in 7.5 weeks using Haohan’s in-house test reports and partner lab in Belo Horizonte (INMETRO-accredited Lab #LAC-009)
- Full Portuguese-language packaging set: blister pack with QR-linked warranty registration, bilingual quick-start guide, and ANVISA-compliant hygiene disclaimer on inner carton
- Production ramped from 5,000 units (Q1 2025) to 18,000 units (Q2 2025), meeting 99.2% on-time delivery across three shipments
Technical Specifications
- Motor: Brushless DC, 12,000 RPM nominal, 18,000 RPM peak
- Power input: 100–240V AC, 50/60Hz; output: 5.0V DC / 2.1A
- Battery: 2,200 mAh Li-ion, 3.7V, cycle life ≥500 charges
- Certifications: INMETRO (NBR IEC 60335-1 & -2-8), RoHS, CB Scheme
- Charging: USB-C fast charge (0–100% in 65 min), LED status indicator
- IP Rating: IPX7 (submersible up to 1m for 30 min)
Commercial Outcomes
- Reduced time-to-market by 11 weeks versus client’s original 20-week internal estimate
- Achieved 94.7% first-pass INMETRO test success rate — no retesting delays
- Enabled client’s Amazon BR launch with FBA-compliant packaging (12 units/carton, 10.2 kg GW)
- Supported 37% MoM sales growth in Q2 2025, driven by verified “220V electric shaver” search traffic
Why This Client Chose Haohan
- Local compliance ownership: Dedicated INMETRO project manager with 12+ years of Brazilian regulatory execution — not outsourced consultants
- Motor-level engineering control: In-house R&D team co-designed the high-RPM motor with thermal modeling validated under 35°C/80% RH conditions
- Vertical manufacturing integration: SMT line, injection molding, and final assembly under one roof — enabling rapid iteration and traceability
- Document-ready localization: Native Portuguese-speaking QA and packaging teams pre-validate all labels, manuals, and marketing assets against ANVISA and INMETRO guidelines
- Scalable minimums: Accepted initial order of 5,000 units (below standard 3,000-pc OEM threshold) with no markup
- Post-certification support: Provided importer registration guidance, NCM code verification, and customs broker referral list

Frequently Asked Questions
Can you produce a Brazilian-market shaver with full INMETRO certification — and handle all documentation, testing coordination, and Portuguese labeling?
Yes. We manage end-to-end INMETRO compliance: NBR IEC 60335-1/-2-8 test planning, lab coordination (accredited Lab #LAC-009), certificate issuance, and native Portuguese labeling — including ANVISA-aligned hygiene claims and importer CNPJ placement.
Do you accept orders below the standard 3,000-pc OEM minimum for high-speed electric razor development?
Yes. We accommodate initial launch volumes as low as 5,000 units for 220V electric shaver projects — with no markup — provided specifications are finalized and tooling is shared across future batches.
How do you ensure motor performance consistency for humid tropical environments — especially for a cordless high-RPM shaver?
We validate thermal management and brushless DC motor stability under 35°C/80% RH conditions. All high-speed electric razor motors undergo accelerated life testing at rated RPM before release.
Can you integrate auto-voltage switching (127V/220V) without external adapters — and support Type N (NBR 14136) plug standard?
Yes. Our power modules auto-detect input voltage (100–240V AC) and regulate output to 5.0V DC. Type N plugs are built-in — not retrofitted — with reinforced strain relief and 10A/20A rating options.
What packaging and logistics support do you provide for Amazon BR FBA or supermarket shelf-ready distribution?
We design FBA-compliant cartons (e.g., 12 units/carton, ≤10.2 kg GW), pre-clear NCM 8510.20.00 classification, and supply DDP Brazil shipping with customs broker referrals and import license guidance.
