OEM Sunglasses FAQ — Practical Answers For Busy Buyers

Standard MOQs are designed for real‑world launches, not warehouses full of unsold stock. Typical ranges:

Yes—when the brief is focused. We combine shared components, limit colorways, and schedule partial runs. It’s a common path for first drops and market tests.

T0 (fit/shape) is 5–10 days on standard parts. T1 (final materials, coatings, labels) is 14–21 days. Complex metalwork, custom molds, or unique hinges add time; we flag it in the brief.

For custom molds paid by you, ownership is yours. We store and maintain them for production security. CADs used for OEM tweaks can be shared under NDA on request.

Yes. We can ship PA12 prints for fast fit checks, or send STL/STEP for your in‑house print. Handy for bridge fit validation.

Pad print, foil stamp, laser engraving, metal inlay, and lens etch. We’ll suggest the method based on material, placement, and wear resistance.

Yes. For acetates, we match with existing plates when possible. For injection, we match masterbatch to your Pantone or physical chip. Tolerance is reviewed under D65 light.

We have dielines for boxes, sleeves, and labels. Your designer can drop artwork in, or our team can adapt your brand kit. See more on Custom Service.

We print EAN/UPC from your GS1 data and test scanability before mass print. Region‑specific warnings and importer text are locked at T1 to avoid retailer portal rejections.

PC (polycarbonate), TAC (tri‑acetate) for polarized, and nylon/PA for light weight and optics. CR‑39 is available for certain silhouettes. All sun lenses are UV400.

All three are available. Polarized is loved for driving and water; photochromic adds day‑to‑night utility; mirrors add style and glare control. We balance VLT, base tint, and mirror density so outdoor performance matches the look.

Backside AR is recommended to cut inner reflections. Anti‑fog is optional and works best with vented sports designs. We have validated coatings on cycling and ski projects.

Yes. We build to EN ISO 12312‑1 for the EU/UK and maintain FDA impact test records for the U.S. We prepare Declarations of Conformity, labels, and retailer file packs. Read more on Quality & Certification.

Incoming checks for lenses and hardware, in‑process torque gates, and final AQL inspection. For department store programs, we tighten AQL for lens cosmetics and do carton drop tests.

Standard is AQL 2.5 for major and 4.0 for minor; lens cosmetic can be tightened to 1.5 when a channel demands it. We align standards in the brief and share reports.

Yes. We coordinate tests with accredited labs when required by retailers. We also share internal pre‑test data so you don’t test blind.

Sampling: 1–3 weeks. Mass production: 35–50 days depending on material and finish. Add time for custom molds or peak season. We plan buffers up front to avoid rush fees.

EXW, FOB, CIF, and DDP for some regions via partners. If you’re new to freight, we can introduce forwarders and help with carton labels, ASN, and pallet plans.

Yes. We pre‑kit by destination, print carton lists by warehouse, and coordinate with your 3PL for delivery windows.

Common codes include 9004.10 for sunglasses and 9004.90 for parts/accessories. Check with your customs broker for the final determination in your market.

We quote per style per color based on materials, finish, lens options, packaging, and order quantity. Shared components lower unit cost. We can show cost ladders so you see where the money goes.

Typical: 30% deposit to start, balance before shipment. For repeat clients we can discuss alternative schedules. Bank transfer is standard; LC is possible for larger programs.

Yes. We warranty manufacturing defects. We also stock selected spare parts for quick fixes in market—screws, nose pads, and temple replacements.

We define a DOA/defect rate threshold in the PO. Above that, we credit or replace in the next shipment. Photo evidence helps us trace root causes fast.

Yes. We supply bio‑acetates and can switch to recycled or FSC packaging on request. We share certificates and keep claims conservative and verifiable.

We maintain systems aligned with major retailer requirements and can host third‑party audits. Share your audit protocol early so we schedule it without delaying MP.

We hold components on fast movers when the forecast is clear. Reorders often ship faster than first runs because artwork and tests are locked.

We keep retain samples and color standards. For acetate, slight variation is normal, and we control it with pre‑production checks under D65 light.

Yes. We can extend a silhouette family with size or hinge variants. It’s a common path after a good first season.

We define exclusivity by silhouette, finish, or region, tied to reasonable volume expectations. Clear scopes protect both sides.

If you commission a custom design and fund unique tooling, it’s yours. For catalog tweaks, we align rights in the PO and NDA.
