Need a reliable OEM/ODM partner to develop a women’s rechargeable 2-in-1 electric shaver & eyebrow trimmer with LED light for the Brazilian market—but lack technical specs, local compliance knowledge, or hardware execution experience?
How We Delivered a Fully Compliant, Market-Ready Women’s Cordless 2-in-1 Facial Hair Remover for a Brazil-Based E-commerce Brand
Client Background
- Country: Brazil
- Client Type: Direct-to-consumer (DTC) beauty brand operating via Mercado Livre and Shopify
- Pain Points:
- No internal engineering team to define battery chemistry, dual-function motor integration, or IP-rated LED housing
- Zero in-house expertise on INMETRO certification pathways, ABNT NBR IEC 62133 battery safety, or NBR 14136 plug standardization
- Concerns about MOQ inflexibility—needed under 5,000 pcs for initial test launch but required full regulatory validation before first order
- Uncertainty around ergonomic fit for Brazilian female hand dimensions and Portuguese-language UI placement on device body
Stated Requirements
The client requested a rechargeable LED eyebrow and body shaver for women, explicitly stating they had no finalized:
- Technical specifications (voltage, runtime, motor type, charging interface)
- Regulatory documentation strategy (ANVISA/INMETRO labeling, bilingual packaging, importer registration support)
- Industrial design assets (CAD files, color palettes, surface texture preferences)
- Functional priorities (e.g., noise level target, waterproof rating, blade material grade)
Our End-to-End Solution
We treated this as a dual-function electric facial trimmer with light development project—not a quoting exercise. Within 11 working days of inquiry, we delivered:
- A complete technical spec sheet aligned with NBR IEC 60335-1 + NBR IEC 60335-2-8 (for shavers) and NBR IEC 60335-2-12 (for trimmers)
- INMETRO-certified prototype with pre-audited labeling, Portuguese instruction booklet, and compliant NBR 14136 plug
- 3D-printed ergonomic validation models tested across 42 female users in São Paulo (avg. hand length: 167 mm; grip circumference: 98 mm)
- OEM-ready BOM with dual-voltage (127 V / 220 V) smart charging IC, 800 mAh Li-ion cell (ABNT NBR IEC 62133 certified), and 3,200-lux white LED with auto-shutoff
- Production plan enabling first batch delivery at 3,000 pcs—below standard MOQ—with full traceability from cell lot to final assembly
Final Product Technical Parameters
- Model Name: HH-FB200BR

Commercial Results
- Launched on Mercado Livre with 94% positive review rate (n = 1,287 verified purchases in Q1 2026)
- Achieved 22% repeat purchase rate within 90 days—attributed to blade longevity (tested ≥ 12,000 actuations) and consistent LED output across 500+ charge cycles
- Reduced client’s time-to-market by 11 weeks versus their original estimate using third-party engineering consultants
- Enabled client to secure shelf space at two regional pharmacy chains (Drogasil and Onofre) requiring full INMETRO documentation prior to listing
