About Sumashi - Your Family-Like Long Term Partner
OUR STORY

We didn't start to sell
screen protectors

We started because overseas brands needed more than a factory. They needed a reliable partner in China who could handle the complexity, maintain quality consistency, and grow with them for the long term. After years of serving clients who struggled with unstable suppliers, communication chaos, and quality inconsistencies, we built Sumashi—a partner that operates like your local team, not just another vendor.

WHO WE ARE

More than a factory,
your integrated partner

Sumashi is a manufacturing-rooted B2B enterprise with a 200-person team dedicated to screen protectors and related accessories. We combine solid production capabilities with trade execution, supply chain integration, and comprehensive service delivery—serving brands and wholesalers across North America and beyond.

🏭

Manufacturing Excellence

Our factory foundation ensures deep product knowledge, quality control from the source, and the ability to customize at scale. You're working with people who understand production, not just paperwork.

🔗

Supply Chain Integration

Beyond our own production, we integrate multiple suppliers to deliver complete product catalogs. One point of contact, one shipment, one quality standard—saving you time, money, and headaches.

🤝

Long-Term Partnership

We focus on North American markets where relationships matter. Our clients don't just place orders—they build sustainable brands with a partner who understands their growth journey and shares their long-term vision.

You need more than a supplier. You need a partner who takes complexity off your plate.

OUR PHILOSOPHY

Built for the long game,
not quick wins

Our positioning isn't marketing language—it's how we actually operate. We measure success by whether your brand grows sustainably, not by how many one-time orders we close. That mindset shapes everything we do.

01

Long-Term Thinking

We don't chase transactions. We build relationships that compound over years. This means we invest time understanding your business, even when you're still small, because we're betting on your growth—not just today's order.

02

Customer Success First

Your profitability and brand reputation matter more to us than short-term margins. We'd rather see you succeed sustainably than maximize a single deal. When you win, we win—and that's how partnerships should work.

03

Growing Together

We're willing to support you before you're "big enough." Small batch trials, patient onboarding, gradual scaling—we've walked this path with clients who started local and became regional leaders. Your growth journey is our growth journey.

We operate like your China-based team, not like a distant factory waiting for orders.

WHAT WE HANDLE

Less worry for you,
more focus on your market

Our customization capabilities aren't about showing off what we can do—they're about taking work off your plate. The less time you spend managing suppliers, the more time you have to sell and grow your brand.

Brand & Packaging Design

Your packaging is the first thing customers see. We help you create packaging structures and visual designs that elevate your brand without requiring you to hire expensive agencies or manage freelancers.

  • Custom box design and structural engineering
  • Brand-aligned visual elements and layouts
  • Market-specific packaging adaptations

E-commerce Visual Support

Selling on Amazon or Shopify requires strong visuals. We provide product photography guidance, infographic templates, and presentation assets so your listings convert better and compete effectively.

  • Product photography and lifestyle imagery
  • Infographic design for feature communication
  • A+ content and storefront visual assets

Multi-SKU & Category Expansion

Growing brands need more than one product. We handle diverse SKU management and help you expand into privacy films, premium materials, and new accessories—without you coordinating multiple factories.

  • Flexible SKU management from samples to scale
  • New product category integration and testing
  • Market-specific product customization

Flexible Production Scaling

Not every product launch needs 10,000 units. We support small test batches for new markets, then scale production as demand grows—giving you the freedom to experiment without massive upfront risk.

  • Low MOQ for market testing and validation
  • Gradual scaling based on real demand
  • Regional customization for North and Latin America

Perfect for brands in growth mode who need flexibility, not factory minimums.

Discuss Your Needs
OUR STANDARD

Quality isn't a feature,
it's your brand reputation

You can't build a brand on inconsistent quality. Every defective batch, every customer complaint, every return—it damages trust you spent months building. We treat quality as a non-negotiable baseline because we understand what's at stake for you.

✓

Batch Consistency Guarantee

Your customers expect the same experience every time. We ensure batch-to-batch consistency through standardized processes and strict material controls—so your brand delivers reliable quality, not lottery results.

🔍

Multi-Stage Inspection

We don't just check finished products. Quality control happens at raw material intake, during production, and before shipping—catching issues before they become your problem and protecting your brand from preventable failures.

⚡

Preventive Problem Solving

The best quality issues are the ones that never reach you. We proactively identify potential problems in design, materials, or production and solve them upstream—before they impact your customers or your reputation.

📋

Documented Standards

Our quality system isn't based on personal judgment—it's documented, traceable, and repeatable. Inspection records, material certifications, and process logs give you transparency and confidence in what you're receiving.

We protect your brand reputation like it's our own—because your success is our success.

HOW WE WORK

Clear process,
predictable outcomes

You don't need surprises—you need reliability. Our workflow is designed to give you visibility, control, and confidence at every stage. Here's exactly how we move from initial conversation to successful delivery.

Discovery & Background

We start by understanding your business model, target market, and specific challenges. This isn't a sales pitch—it's about determining if we're the right fit and how we can genuinely help you grow.

01

Product & Solution Design

Based on your needs, we recommend specific products, packaging structures, and visual approaches. You get options that balance quality, cost, and market positioning—not just what's easiest for us to produce.

02

Sampling & Testing

We create samples that reflect actual production quality. You test, we refine, and we iterate until it's right. No rushing to production before you're confident in what you're getting.

03

Production & Quality Control

Manufacturing begins with documented standards and multi-stage inspections. We proactively monitor batch consistency and flag any issues before they become your problem.

04

Integration & Consolidation

If you're ordering multiple products or categories, we coordinate across suppliers, conduct unified quality checks, and consolidate everything into one shipment—saving you logistics headaches.

05

Shipping & Ongoing Support

Products are packaged, documented, and shipped with full transparency. Post-delivery, we stay engaged—helping with new opportunities, product expansions, and market feedback.

06

Structured, transparent, and built for your peace of mind.

OUR ADVANTAGE

One partner, fewer problems,
complete catalog

Managing five suppliers means five points of failure. We consolidate your supply chain so you deal with one trusted partner who coordinates everything—from sourcing to quality control to final delivery. That's the real value of integration.

🔍

Supplier Vetting & Selection

We don't just connect you with factories—we screen, evaluate, and select suppliers based on quality track records, production capacity, and long-term reliability. You skip the trial-and-error phase entirely.

📊

Unified Quality Standards

Different suppliers, one quality bar. We apply consistent inspection protocols across all products and categories, ensuring your brand experience remains uniform regardless of who manufactures what.

📦

Consolidated Logistics

Multiple products, multiple factories—one coordinated shipment. We handle cross-supplier scheduling, inspection, packaging, and shipping coordination so you receive everything together, on time, ready to sell.

This is how you scale product lines without scaling headaches.

CLIENT VOICES

What partnership
actually feels like

These testimonials focus on what really matters: communication quality, stress reduction, and whether we actually deliver on promises. This is what clients say when they're not on a sales call.

"

The biggest difference? I don't worry anymore. Quality is consistent, communication is clear, and when issues come up—which is rare—they solve them before I even know there was a problem. It's like having a team in China instead of a vendor.

Brand Owner, California

"

What impressed me wasn't just the product quality—it was how they think. They're not trying to close a deal; they're trying to help my business succeed. That's a completely different relationship than I've had with other suppliers.

Carlos R.

Wholesale Director, Mexico

"

We were juggling four suppliers and it was a nightmare. Sumashi consolidated everything, improved our packaging, and actually reduced our costs. Now I spend my time growing the business instead of managing logistics. That's real value.

Operations Manager, Texas

"

They understood our business from day one. We're not a huge company, but they treated us like we mattered. Two years later, we've tripled our product line and they've been with us every step. That's partnership, not just supply.

HOW WE OPERATE

Built to last,
not built on one person

A 200-person team isn't about size—it's about sustainability. When you partner with us, you're working with systems, processes, and departments that function reliably whether it's Monday or Friday, January or December. That stability protects your business.

👥

Team Stability & Structure

Our core team members have been with us for years, not months. You won't lose context or relationships because someone left. Institutional knowledge is preserved, and your account continuity is protected by team depth, not individual dependency.

🔄

Cross-Functional Collaboration

Sales, production, quality control, and logistics work as one system—not isolated silos. When you communicate with us, information flows internally so you're not repeating yourself or managing disconnected departments.

💬

Communication Excellence

We respond promptly, speak clearly, and don't hide behind jargon or excuses. You get honest timelines, proactive updates, and direct answers. Communication isn't an afterthought—it's how we build trust and prevent problems.

⚡

Execution Discipline

We don't over-promise and under-deliver. Deadlines mean something, commitments are kept, and when issues arise, we address them immediately with solutions—not excuses. Your trust is earned through consistent follow-through, not good intentions.

Work with a team that treats your business like it's their own.

OUR PERSPECTIVE

Why we think differently
about this industry

Most factories chase volume and low prices. We don't. We believe the screen protector and accessories market rewards quality, consistency, and long-term brand value—not race-to-the-bottom pricing. This philosophy shapes everything we do.

01

Product Evolution Over Commoditization

Screen protectors aren't static products. New materials, privacy features, and application methods constantly emerge. We invest in staying ahead of trends so our partners can offer innovation, not just inventory.

02

Quality Wins Long-Term

Low-price suppliers attract one-time buyers. High-quality suppliers build brands that customers return to. We've seen this play out hundreds of times: brands that prioritize quality outlast those that compete on price alone.

03

Brand Value Compounds

Short-term profit comes from margins. Long-term wealth comes from brand equity. We help clients build recognizable brands that command loyalty and premium positioning—not generic products competing in saturated markets.

Partner with someone who sees the same long game you do.
