Product Questions and Answers

Q1. Are metal sunglasses compliant with CE, FDA, and UV400 standards?

Yes. Professional metal sunglasses are manufactured to meet CE (EN ISO 12312-1) and FDA requirements, with lenses providing UV400 protection that blocks 100% of UVA and UVB rays. Compliance documentation and test reports are typically available for import clearance and brand audits.

Q2. What types of metal materials are commonly used in metal sunglasses?

Common materials include stainless steel, aluminum, monel, nickel-silver alloy, and titanium. Buyers select materials based on weight, corrosion resistance, flexibility, and target price point. Nickel-free options are widely available for EU markets.

3. Are metal sunglasses lightweight and comfortable for long-term wear?

Yes. Modern metal sunglasses use thin-gauge alloys and hollow temples to reduce weight while maintaining strength. Adjustable nose pads and ergonomic temple tips improve comfort, making them suitable for all-day wear and premium positioning.

Q4. Can metal sunglasses be customized with logo, colors, and lens options?

Absolutely. OEM/ODM services typically include laser logo engraving, temple stamping, custom plating colors, and lens options such as polarized, mirrored, gradient, or photochromic lenses, supporting private-label and brand differentiation.

Q5. How durable are metal sunglasses compared with plastic frames?

Metal sunglasses offer higher structural stability, better heat resistance, and longer shape retention than most plastic frames. Stainless steel and titanium models perform especially well in hot climates and high-use retail environments.

Q6. Are metal sunglasses suitable for polarized lenses?

Yes. Metal frames are fully compatible with polarized TAC or nylon lenses, commonly used for driving, outdoor, and sports applications. Polarization specifications and lens test data can be provided upon request.

Q7. What is the typical MOQ and lead time for metal sunglasses orders?

Ready-stock reading glasses with logo customization start from 300 pcs on selected styles. OEM/ODM projects usually start from 600 pcs per model depending on design and customization level. Sampling takes 5–7 days, while mass production generally requires 30–45 days, excluding shipping.

Q8. What quality control processes are applied to metal sunglasses?

Quality control includes material inspection, welding strength tests, hinge fatigue testing, salt-spray corrosion tests, lens impact tests, and final visual inspection, ensuring consistent quality across bulk orders and repeat production.

Q9: What payment methods do you accept?

We accept Bank Transfer (T/T) for bulk orders. PayPal and credit cards are available for samples or small quantity orders. Payment terms can be discussed based on order value and cooperation history.
