About Wenzhou Hindar Optical Co., Ltd - Optical Frames Supplier in China

Wenzhou Hindar Optical Co., Ltd is based in Wenzhou, China and currently lists five distinct optical products. The catalogue includes titanium and beta‑titanium frames, acetate frames, general optical frames, reading glasses and a line of high‑quality sunglasses. These items are classified under HS chapter 90, heading 9004 which covers spectacles, frames and parts. The supplier’s active product count of five reflects a focused portfolio rather than a broad assortment. All products are manufactured for export and are listed as imported‑tier items in international trade platforms.

Titanium and beta‑titanium frames are valued for high strength‑to‑weight ratio and corrosion resistance. Acetate frames provide a lightweight, hypo‑allergenic alternative with a broad selection of colour options. Reading glasses are typically produced with single‑vision lenses and a standard near addition of +1.00 to +2.50 diopters. The sunglasses range is designed to meet UV‑400 protection standards, blocking at least 99 % of UVA and UVB radiation. Each product family can be supplied in bulk packaging suitable for 20‑foot or 40‑foot containers.

Product Range and Specialties of Wenzhou Hindar Optical Co., Ltd

The current catalogue lists five product families: titanium and beta‑titanium frames, acetate frames, standard optical frames, reading glasses and UV‑400 sunglasses. In the eyewear industry, titanium frames are often produced from Grade 5 (Ti‑6Al‑4V) alloy, while beta‑titanium alloys such as Ti‑15V‑3Cr‑3Sn‑3Al are used for flexible yet strong rims. Acetate frames are commonly made from cellulose acetate sheets with a typical thickness of 1.5 mm and may be dyed using solvent‑based or UV‑cured processes. Reading glasses usually employ CR‑39 or polycarbonate lenses with a standard bridge width of 16‑18 mm and temple length of 135‑145 mm. Sunglasses intended for export generally meet UV‑400 standards, have a minimum transmittance of 1 % visible light, and may be supplied with polarized or non‑polarized lenses depending on buyer specification.

Trade and Export Information - Wenzhou Hindar Optical Co., Ltd

China is the world’s largest exporter of eyewear, and products from Wenzhou commonly ship to the European Union, United States, Middle East and Southeast Asian markets. Under HS heading 9004, frames are typically declared with sub‑heading 9004.10 and sunglasses with 9004.90, which determines duty rates and import documentation. Importers often require CE marking for EU shipments, FDA 510(k) clearance or Class II registration for the US, and ISO 13485 or ISO 9001 quality system certificates. Standard export packaging includes individual cardboard boxes, bulk shrink‑wrap, and loading into 20‑foot or 40‑foot containers with palletized stacking to protect frame geometry. Common Incoterms used by Chinese eyewear exporters are FOB Wenzhou Port or CIF destination ports, allowing buyers to manage freight and insurance according to their logistics strategy. Seasonal demand peaks in Q4 for sunglasses and Q1 for reading glasses, influencing lead times and container availability.

Buyers should request detailed material data sheets specifying alloy grade for titanium frames or cellulose acetate composition for acetate frames. Verification of UV protection for sunglasses should include a UV‑400 test report and, where applicable, polarization performance data.

Common minimum order quantities range from 500 to 1,000 units per style, with lead times of 30‑45 days after order confirmation and receipt of required certifications.

Packaging dimensions (e.g., 12 × 8 × 5 cm per frame) and weight (approximately 30 g for titanium frames) should be confirmed to calculate freight costs accurately.
