How to Choose a White-Label Window Film OEM Partner
White-label window film is one of the highest-margin private-label opportunities in the auto and architectural aftermarket. It's also one where a bad supplier choice can destroy a dealer brand. Here's what to verify before signing.
1. Are they actually a manufacturer?
This is the most-skipped due-diligence step. Many "OEM partners" are actually converters or rebrand-only intermediaries. Three quick checks:
- Do they own a sputter and/or ceramic deposition line? Ask for the equipment make/model and a cleanroom audit certificate.
- Do they publish their own SKU catalogue with spec sheets, or do all "their" products look like a competitor's catalogue?
- Will they let you visit the factory? (Real manufacturers welcome customer visits with 2–4 weeks notice.)
2. What's the actual MOQ — and what's flexible?
Industry standard MOQ for white-label is 500 rolls per SKU. Some partners flex this to 300 for a first PO with the understanding that you'll grow. Others insist on 1,000+ rolls per SKU which prices out smaller regional brands.
Equally important: what's the MOQ for custom packaging? Some suppliers will run a 500-roll order on stock packaging but require 5,000+ rolls for custom-branded boxes. If that's a deal-breaker, get it in writing up front.
3. Branding scope
"White-label" means different things to different suppliers. The 4 levels:
- Stock packaging with your logo sticker. Bare minimum — your customer will figure it out.
- Custom box with your wordmark + PMS colors. Standard mid-tier offering.
- Custom box + custom core print + custom spec sheet under your brand + warranty card under your brand. Premium tier — what LUNOX OEM customers get.
- Full custom formulation under your brand. Reserved for 5,000+ roll programs where R&D investment is justified.
Specify which level you need on day one. Mid-program upgrades typically cost 20–30% more than spec'ing it correctly from the start.
4. Sample policy
Real OEM partners ship sample kits within a week of inquiry, free of charge for verified B2B buyers. They include:
- VLT / IR / TSER swatch cards for the families you're interested in.
- A representative roll sample (typically 30 cm × 30 cm) of your lead SKU.
- Technical data sheet, certificate of analysis, warranty terms.
If a supplier asks you to pay for samples or stretches the timeline to 4+ weeks, that's a signal about how they'll treat you when you're a 500-roll customer.
5. Exclusivity and territory
By default, OEM suppliers do not grant territory exclusivity — they want to sell to as many regional brands as possible. That's fine for most buyers (you compete on installer network and brand positioning, not on SKU access).
If exclusivity matters, expect to pay 15–30% premium and commit to a multi-year volume floor. LUNOX offers single-country exclusivity from 5,000+ annual rolls.
6. Lead time reality
Industry standard: 4–6 weeks on standard packaging, +2–3 weeks on custom packaging. Ask for the supplier's average lead time over the last 6 orders — not the marketing number. If their actual delivery is consistently 8+ weeks, you'll need to carry more inventory than your business plan assumed.
7. Exit clause
Read the termination terms. Specifically: do you keep your custom-printed packaging on hand at the supplier? Can you transfer to another OEM partner mid-program? What happens to in-progress inventory if you cancel? These get glossed over until they matter — and then they always matter.
