Constar lifts lens output to 15 million a month across six China plants

Gansu Constar Technology Group says its six facilities in Gansu and Hunan now can produce more than 15 million contact lenses per month, expanding its ability to supply private-label brands and distributors in more than 50 countries. The company says the scale, along with FDA, CE and ISO 13485 certifications, helps it meet both volume and regulatory demands for global markets.

Why it matters: - Constar says the 15 million-per-month capacity gives brand owners room to scale from small test orders to large quarterly runs without switching suppliers. - The company says the production network is built to support private-label brands, distributors and multi-market compliance across 50+ countries. - The scale also covers more than contact lenses, including lens care products, eye wash products and starter kit bundles.

What happened: - Gansu Constar Technology Group said on August 11, 2026 that it now operates six production facilities across Gansu and Hunan provinces in China. - The company said the network has a combined monthly capacity of more than 15 million lenses. - Constar said the facilities produce color contact lenses, clear prescription lenses, daily disposables, monthly replacements and specialty cosplay designs.

The details: - The six-site network includes headquarters in Baiyin, Gansu Province; a second Gansu site for color lens production and cleanroom operations; a third Gansu site for clear lens production and AOI inspection; and three Hunan facilities for color lenses, daily disposables, and care products, packaging and fulfillment. - Constar said the distributed model improves production efficiency, supply chain resilience and quality control. - The company said if one facility has maintenance downtime or capacity limits, production can shift to other sites without affecting delivery timelines. - Constar said its facilities use more than 500 automated production machines, including Automated Optical Inspection systems that check for dimensional and surface defects. - Each facility operates in cleanroom conditions with controlled temperature and humidity. - The company said quality control runs from raw material verification through in-process monitoring to final product testing. - Every production batch receives a Certificate of Analysis covering dimensional accuracy, optical clarity, color consistency and biocompatibility compliance. - Constar said its production network operates under FDA, CE 0197 and ISO 13485 certifications. - The company said it also holds regional certifications for Indonesia, Australia and Saudi Arabia, including AKL, TGA and SFDA. - Compliance documents such as CE certificates, ISO documentation, QC reports and HS codes ship with every order. - Constar said it serves partners in more than 50 countries. - The company said it has 500+ in-stock SKUs for immediate shipment. - Constar said its integrated design studio develops 1,000 new patterns each month. - The company said full production runs take 30 to 45 days, depending on order size.

Between the lines: - The 15 million-lens figure matters because contact lens brands often struggle to move from small initial orders to much larger volumes without long lead times. - Constar is positioning itself as a single supplier for both volume manufacturing and regulatory paperwork, which can simplify cross-border sales for private-label brands. - The company is also signaling operational redundancy, which is a selling point for buyers that need consistent replenishment during seasonal demand spikes. - Michael Zhang, Constar’s Director of Business Development, said capacity determines whether a supplier can keep a growing brand or force it to look elsewhere. - Dr. Wei Lin, head of quality assurance, said automation and inspection systems are meant to keep the ten-millionth lens as consistent as the first.

What's next: - Constar says it is offering complimentary production consultations and product samples to qualified inquiries. - The company is using the expanded capacity to target seasonal demand, including Halloween, convention season and holiday gifting. - Brand owners and distributors can use the network for multi-brand production, custom designs and faster market testing.

The bottom line: - Constar is betting that scale, automation and certifications will make it a go-to manufacturer for private-label contact lens brands that need both volume and compliance.
