China Wholesale Sunglasses Manufacturer & Factories Serving the Seattle Market

We maintain dedicated FOB, CIF, and DDP (Delivered Duty Paid) shipping lanes directly connecting our central manufacturing hubs to the Port of Seattle (Northwest Seaport Alliance) and Seattle-Tacoma International Airport (SEA). For air freight sample rollouts, lead time averages 4–6 business days via DHL/FedEx Express. For full-container ocean freight, sailing windows from Ningbo or Shenzhen directly into Puget Sound typically conclude in 14–18 maritime days, with all ISF-10 filings, Lacey Act declarations (for wood composite packaging), and FDA medical device entry filings executed prior to port arrival.

Yes. All optical silhouettes are shipped with demo lenses designed to maintain structural eyewire geometry during international transit. Eyewire grooves are micro-milled with standard 0.6mm V-bevel depths and 115° included angles, perfectly synchronized for standard Santinelli, Essilor, and Briot 3D optical lab edgers. Whether an independent lab in Pike Place or an optometry franchise in Kirkland is fitting high-index 1.67, 1.74, or digital progressive lenses, the frames accept cold-snap or mild thermal insertion without stress fractures or barrel warping.

To empower boutique chains and scaling regional brands, our factory offers tiered MOQ configurations. For in-stock ready-to-ship core collections (such as our Aiden, Aksel, and Vesper silhouettes), we provide laser logo engraving, custom temple foil stamping, and personalized case bundling starting at 100 units total (mixed across 2–3 colorways). For bespoke ground-up OEM/ODM toolings featuring proprietary acetate color laminations and custom-machined metal cores, our baseline starts at 300 units per style (100 units per colorway).

Absolutely. Given Seattle's characteristic cloud cover paired with high indirect atmospheric UV scatter, standard dark Category 4 lenses diminish contrast excessively. We specialize in producing custom Category 2 and Category 3 amber, copper-rose, and selective yellow-tint polarized CR-39 and nylon lenses. These specialized tints increase contrast in flat-light conditions while internal anti-reflective (AR) back-surface coatings eliminate annoying ghost reflections from peripheral maritime water surfaces.

Prior to dispatch, randomized production samples undergo rigorous environmental chamber stress testing. This includes a 48-hour continuous salt-spray chamber exposure (ASTM B117) to verify corrosion resistance on titanium platings and stainless-steel rivets, followed by rapid thermal cycle testing (-10°C to +50°C at 90% relative humidity) to ensure acetate slabs undergo zero dimensional distortion, shrinkage, or lens pop-out under rapid climate transition from indoor Pacific Northwest heating to cold outdoor rainfall.
