India's B2B Sunglasses Marketplace — 160+ Verified Manufacturers, UV400 to Polarised to Sports

What is UV400 protection and why is it essential in sunglasses?

Answer: UV400 means the lens blocks 100% of all ultraviolet radiation up to 400 nanometres – covering both UVA (315–400nm) and UVB (280–315nm) wavelengths completely. It is the internationally recognised gold standard for sun protection eyewear. Sunglasses without genuine UV400 protection – even dark-tinted ones – cause the pupil to dilate in reduced visible light, allowing more UV radiation to enter the eye than bare eyes would permit. Long-term exposure accelerates cataract development and increases macular degeneration risk, both of which are irreversible.

What is IS 14812 and is it mandatory for selling sunglasses in India?

Answer: IS 14812 is the Bureau of Indian Standards (BIS) standard for sunglasses in India, covering UV transmittance limits, optical power and prismatic requirements, lens quality standards, and labelling requirements. It is a legally applicable standard under the BIS Act. While enforcement in the unorganised market has historically been inconsistent, BIS raids on non-compliant retailers and importers have intensified significantly since 2023. Stocking non-compliant sunglasses creates concrete consumer protection liability risk under India's Consumer Protection Act 2019.

What is the difference between TAC and glass polarised lenses?

Answer: TAC (Tri-Acetate Cellulose) polarised lenses are the industry standard for mid-range polarised sunglasses – lightweight, scratch-resistant, and cost-effective. They provide excellent glare reduction for driving, outdoor sports, and general use. Glass polarised lenses offer superior optical clarity, higher scratch resistance, and more precise polarisation axis alignment – preferred for premium applications and professional outdoor use. TAC polarised suits the majority of retail buyers; glass polarised commands a 30–50% premium.

What is the standard MOQ for sunglasses wholesale?

Answer: Most Trade4Asia-verified manufacturers accept 50 pairs per style as the standard minimum. For standard catalogue fashion designs, some suppliers accept 24-pair MOQs. Custom-branded sunglasses – with custom temple print, branded case, or exclusive lens tint – typically require 100 pairs minimum to make branding economically viable. Sports and safety eyewear with specific certifications generally require 50–100 pairs minimum per model.

Can Indian manufacturers produce private label sunglasses?

Answer: Yes. Verified Trade4Asia manufacturers offer comprehensive private label services including custom temple logo printing (screen print or pad print), branded hard and soft cases, custom lens tint colours, micro-print on lens (brand name), and fully branded outer packaging boxes. Private label typically requires 100–200 pairs per style. Most manufacturers can produce custom samples within 7–10 working days for approval before bulk production.
