Reorder and Inventory Planning for Sunglasses

Sunglasses are intensely seasonal, and a stockout in May costs you the whole summer. Good inventory planning turns lead time from a risk into a routine. Here is how to set reorder points and safety stock for a sunglasses program.

Why sunglasses inventory is hard

Demand peaks sharply before and during summer, lead times run 8–12 weeks including freight, and styles can be trend-sensitive. Plan poorly and you either stock out at peak or sit on dead inventory in winter.

The reorder point formula

Reorder point = (average daily demand × lead time in days) + safety stock. With an 80-day total lead time, even modest daily demand means you must reorder months before you run dry.

Building in seasonality

• Forecast by month, not annually — demand is not flat
• Place pre-season orders to land by March/April
• Hold core styles deeper than fashion styles
• Plan a clearance path for end-of-season stock

Safety stock and service level

Safety stock buffers demand and lead-time variability. A higher service level (fewer stockouts) needs more safety stock and ties up cash — balance it against carrying cost. For fast restocks, air freight can shorten the effective lead time.

In sunglasses, the calendar is your enemy. The order you place in February is the inventory you sell in June — there is no catching up once peak begins.

Faster reorders with a manufacturing partner

Reorders are faster than first orders: tooling exists, the tech pack is approved and specs are locked. We hold moulds and can pre-stage components for repeat programs, cutting reorder lead time — see lead times in our sourcing guides.

How LumiShades supports planning

We keep your tooling and approved specs on file, advise on pre-season timing, and offer air freight for urgent restocks. Use our free buyer tools to model order quantities against demand.

Buyer takeaways

Calculate reorder points from real lead times, forecast by month, and place pre-season orders early. request a quote to set up a reorder cadence that keeps you in stock through summer.

Why source this from Wenzhou with LumiShades

Wenzhou in Zhejiang Province is widely regarded as China’s eyewear manufacturing capital, producing a large share of the world’s sunglasses. That concentration matters to buyers: a deep local supply chain for acetate sheet, hinges, lens blanks, plating and packaging means shorter component lead times, easier color and material matching, and a workforce with decades of eyewear-specific skill. LumiShades has manufactured in this ecosystem since 2009, and our vertical integration — in-house injection molding, acetate cutting, CNC milling, lens tinting, decoration and quality control — means no part of a well-planned sunglasses inventory is quietly subcontracted to a workshop you cannot audit.

For international buyers, that vertical control translates into accountability. When a single factory owns every step, defects are traced and fixed at source rather than bounced between vendors, and your specifications survive intact from first sample to bulk. We back this with 15+ years of experience, shipments to 60+ countries, more than 5 million pairs produced per year and a 98.5% on-time delivery rate. Our certifications — CE EN ISO 12312-1, FDA registration, ANSI Z80.3, AS/NZS 1067, REACH, ISO 9001 and BSCI audit — mean the compliance documentation your market requires already exists. Explore our manufacturing capabilities and quality control process to see how this works in practice.

Frequently asked questions

What is the minimum order quantity? Our MOQ is 50 pairs per design, which lets new brands and buyers validate a well-planned sunglasses inventory before committing to volume. Pricing improves at 300, 1,000 and 5,000+ pairs, dropping as low as $2.10 per pair on volume programs.

How long does it take? Samples are ready in 7–10 days and bulk production runs 25–35 days, plus QC, packing and shipping. Using an existing frame shape avoids new tooling and is the fastest route; fully custom moulds and acetate builds add time.

Can you handle custom branding and compliance documentation? Yes. We decorate in-house (laser engraving, pad printing, metal logo plates, custom temple colors and packaging) and provide the UV, impact and standard-specific test reports your destination markets require. Tell us your target countries up front and we build the right documentation into the order.
