Compare Custom Sunglasses Quotes Like for Like

If custom sunglasses quotes are far apart, the problem is usually not margin. It is mismatched assumptions. One supplier may be pricing a PC injection frame with AC lenses, a pad-printed logo, PE bag packing, and no test budget. Another may be pricing TR90, hard-coated PC lenses, spring hinges, a microfiber pouch, a retail box, and third-party testing. On paper, both are quoting "the same style." They are not quoting the same build. Fair comparison starts with a locked spec: construction, lens spec, branding method, packaging standard, MOQ basis, testing scope, and trade term. Do that first. Then the price gap usually makes sense.

Start with one locked quote sheet, not a mood board

The fastest way to ruin quote comparison is to send a few reference photos and ask factories to "quote this look." Photos do not define resin grade, lens thickness, hinge construction, logo method, packing labor, or testing scope. Suppliers fill in those blanks differently. Cost moves with every assumption.

Use a one-page quote sheet. Require every supplier to price that exact sheet. If a supplier wants to suggest a cheaper or upgraded option, ask for it in a separate column. Do not let them change the base spec.

• Frame construction: full injection, acetate CNC-cut, stamped metal, wire-core temple, or mixed material.
• Material grade: PC, TR90, acetate thickness in mm, stainless steel grade, cupro-nickel, hinge type, and whether spring hinges are included.
• Lens build: AC, PC, nylon, TAC polarized; thickness; base curve; tint; hard coat or mirror if required.
• Branding: pad print, screen print, laser marking, hot foil, die-cast logo plate, lens marking.
• Packaging: PE bag, pouch, case, cleaning cloth, instruction leaflet, barcode label, retail box, export carton pack-out.
• Compliance: destination market requirement, chemical compliance requirement, and whether testing is on preproduction samples, first production, or by lot.
• Quantity logic: total units, units per color, units per logo version, and whether MOQ applies per design or per SKU.

Add tolerances where they matter. A factory should not only see 52-20-145. It should see approved dimensions, allowed variation, target weight if relevant, and any fit or appearance requirement. If you do not define tolerance, suppliers can cut cost by changing wall thickness, lens thickness, or hardware and still claim they matched the photo.

Normalize the frame first

After the lens line, frame construction is often the main reason quotes drift apart. PC injection, TR90, acetate, and metal are not the same cost base. They use different processes. They need different labor. Scrap, polishing, fitting, and tooling all change.

Push suppliers to state their assumptions in stress areas: end piece, hinge seat, and temple bend. A low quote may reflect a lighter build or simpler hardware, not better efficiency. If durability matters, require the exact hinge type, barrel count, temple core if used, and any spring-hinge inclusion.

Weight matters too. Two frames can look similar in photos and perform very differently if one uses less material. For wrap or sport styles, define the intended lens base curve and make the supplier confirm frame compatibility. That avoids fitting stress, loose lens retention, and distortion caused by mismatched geometry.

Also check mold status. Is the quote based on an existing shared mold with only color and logo changes? Or does it assume new front and temple tooling? New injection tooling should be quoted separately, with clear terms on ownership, maintenance, modification responsibility, and whether the tool is exclusive or shared.

Lock the lens spec with numbers

Big quote gaps often hide in the lens line. A style quoted with thin AC lenses can look similar in photos to one built with hard-coated PC lenses. Cost is different. Performance is different.

At minimum, your RFQ should state lens material, thickness, base curve, tint, coating, UV requirement, and testing requirement.

• AC lens: lower cost and common in fashion sunglasses; buyers should confirm whether its performance is suitable for the target market and use case.
• PC lens: commonly used where lighter weight and higher impact resistance are required; hard coat should be specified if scratch resistance matters.
• Nylon lens: used in some higher-performance applications; buyers should define the optical and durability requirements rather than request it by name alone.
• TAC polarized: laminated polarized construction; buyers should specify thickness, polarization requirement, and appearance standard.

Use numbers. Not adjectives. "Standard lens" is not a real specification. State thickness, any allowed tolerance, and whether hard coat, mirror, anti-reflective treatment, or polarization is included. If the product is for a regulated market, name the required market standard in the RFQ instead of asking for a generic "UV400 certificate."

For Europe, sunglasses sold as personal eye protection are commonly assessed to EN ISO 12312-1 and often placed on the market with CE marking where applicable. For the United States, buyers commonly reference ANSI Z80.3. For Australia and New Zealand, buyers commonly reference AS/NZS 1067. Chemical compliance may also need separate review, for example under REACH for the EU. These are not interchangeable. The quote should state exactly which requirement is included.

For polarized lenses, ask whether final QC includes orientation check, cosmetic inspection for bubbles or delamination, and any heat or adhesion checks the supplier normally performs. If two quotes are far apart, inspect the lens build first.

Break out branding and decoration by process

Logo cost is not just artwork cost. It includes process, setup, fixtures, labor, and cosmetic risk. A simple one-color inside-temple pad print is not comparable to a custom metal logo plate, a laser-marked lens, or an embossed temple detail.

Break each decoration line out in the quote and ask suppliers to show setup charges. Have them list:

• Outside-temple logo method and size in mm
• Inside-temple legal and brand print method, number of print colors, and print length
• Lens logo or lens marking method if any
• One-time tooling for logo plate, print plate, laser fixture, or emboss die
• Any special assembly step required for the decoration

Then define acceptance criteria. Examples: logo position tolerance, legibility standard, no missing print, no visible glue overflow, and no obvious defects under the agreed inspection condition. If a metal plate is used, confirm whether the frame already includes the recess or slot. If not, the decoration cost may actually include a structure change.

Branding method also affects lead time. Pad-print setup is usually fast. Custom metal hardware is not. If the inside-temple print must include model data, importer details, or market information, provide the exact content early so suppliers quote the same print length and operation count.

Packaging changes both unit cost and freight

Packaging is a common reason a low ex-factory quote loses after landed-cost review. One supplier may quote PE bag only. Another may include pouch, cloth, barcode sticker, case, retail box, and carton limits. That is not a small difference. It changes material cost, packing labor, carton dimensions, and freight efficiency.

Specify each packaging component line by line:

1. Primary pack: PE bag, recycled polybag, or microfiber pouch
2. Temple or lens protection sticker yes/no
3. Barcode label content, format, and placement
4. Leaflet or compliance insert required or not
5. Case type: fold case, EVA zip case, or hard shell
6. Retail box: flat-packed or assembled by factory
7. Export carton target: max gross weight, carton dimensions, units per carton

Carton count matters because freight is based on volume and weight, not pair count alone. A supplier quoting pouch-only packing is not quoting the same delivered cost as one including a bulky case and an assembled retail box. For e-commerce programs, also confirm whether carton markings, insert sequence, or retailer-specific packing instructions add manual labor.

Packaging can have its own MOQ logic. A sunglasses MOQ may be low, but a custom printed box, barcode label, or insert may have a higher minimum run from the packaging vendor. Ask suppliers to break out those thresholds clearly. Otherwise you may compare a basic sunglasses quote with a fully retail-ready quote and miss the difference.

Separate unit price from one-time cost and MOQ logic

To compare fairly, split recurring production cost from one-time and occasional charges. A transparent supplier can look expensive only because it showed mold cost, logo tooling, and test fees while another supplier left them out of the first quote.

Then normalize the quantity basis. A price for 1,000 pairs total across two colors is not directly comparable to 1,000 pairs split across many colors or logo versions. More variants mean more setup, more WIP separation, and less efficiency. The same problem shows up in MOQ language. "300 pairs MOQ" may mean 300 total for one shared-mold style, while another supplier means 300 per color or per logo version.

Ask every supplier to quote the same breakpoints and state whether the price tier applies per design, per color, or total mixed order. Then confirm the trade term: EXW, FOB, or another agreed basis. A lower EXW price is not automatically better than a higher FOB price if the first quote excludes local charges and port cost.

Name the testing and documents exactly

Do not ask suppliers to "provide certificates" or "meet all standards." That wording is too vague. Sunglasses compliance depends on market, product category, materials, and claims. The RFQ should name the required standard or document and state whether the quote includes any test allocation.

Examples of commonly requested items include:

• EN ISO 12312-1 for sunglasses sold in applicable European markets
• ANSI Z80.3 for the United States market
• AS/NZS 1067 for Australia and New Zealand
• REACH for relevant chemical compliance requirements in the EU supply chain
• ISO 9001 if the buyer requires a quality-management-system certificate from the supplier
• BSCI if the buyer requires a social compliance audit result
• FDA registration only where it is actually relevant to the product category and the buyer's import program; do not request it as a generic eyewear document

These documents do not prove the same thing. Product test reports, chemical compliance declarations, factory management certificates, and social audit results are different. Keep them separate.

If testing is required, specify:

1. The exact standard or protocol
2. Who chooses the lab
3. Whether testing is on preproduction samples or finished goods
4. Who pays if a retest is required
5. What documents must be delivered before shipment

This prevents one supplier from quoting without test cost while another includes a third-party lab budget. It also reduces the risk of receiving irrelevant or outdated documents that do not match the actual style, material set, or destination market.

Match lead time to the real process

A short lead time only matters if it covers the same work. A supplier using an existing shared mold, standard packaging, and simple pad printing can move faster than one developing new tooling, custom logo hardware, and printed retail boxes. So review lead time against the process, not as a single headline number.

Ask the factory to break lead time by step:

1. Artwork confirmation and engineering review
2. Material preparation and color matching
3. Mold modification or fixture setup if needed
4. Sample build and approval cycle
5. Mass molding or CNC cutting
6. Lens production, coating, and tinting
7. Logo application and assembly
8. Final QC, packing, and booking

This exposes whether a supplier is quoting from real readiness or from best-case assumptions. Acetate usually needs more hand-finishing than basic injection styles. Custom metal logo parts and printed packaging can also become the critical path if approvals are late.

Before award, send a final comparison sheet and ask for written confirmation against every commercial and technical line. Include:

• Frame material, finish, hinge type, and target weight if required
• Lens material, thickness, coating, and required market standard
• Logo method, location, and one-time tooling
• Packaging contents, units per carton, and carton limits
• MOQ basis, volume-break basis, and quoted trade term
• Sample lead time, bulk lead time, and quote validity
• QC method, inspection standard if used, and testing responsibility

Last check: who performs QC, and when? Incoming material check, in-line inspection, final random inspection, and carton verification should all be defined. If not, even a detailed quote can drift during production.

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 your order 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

Should I ask every factory for their "best price" before I finalize specs? No. That usually produces low numbers built on different assumptions, which makes comparison unreliable. First issue one common spec sheet that locks frame material, lens material and thickness, logo method, packaging, testing scope, MOQ basis, and trade term. Then ask each supplier to quote that same baseline. If you want cost-down options, request them as separate alternatives with the exact changes stated line by line.

What is the most common reason one sunglasses quote is much lower than another? Usually the lower quote is based on a different build, especially in the lens and frame lines. Common differences include AC instead of PC or TAC, thinner lenses, lighter frame construction, simpler hinges, fewer decoration steps, basic PE-bag packing instead of retail packaging, or no allowance for testing. Ask each supplier to complete a comparison table showing material, thickness, hardware, logo process, packaging contents, and compliance scope. The mismatch usually becomes clear fast.

How should I compare MOQ if factories state it differently? Do not accept MOQ as a single number without definition. Ask four follow-up questions: 1) Is MOQ per design or per total order? 2) Is it per color? 3) Is it per logo version or artwork change? 4) Do packaging items such as boxes, labels, or cases have their own MOQs? Put the answers into one sheet so you can compare on the same basis. This prevents a nominally low MOQ from turning into a much higher effective minimum once colors and packaging are added.

Do I need to pay for compliance testing on every order? Not always, but you do need a written testing policy. The right approach depends on the destination market, the standard being used, whether the design or material set has changed, and your risk tolerance. At minimum, define the required standard—for example EN ISO 12312-1, ANSI Z80.3, AS/NZS 1067, or REACH where relevant—then agree whether testing is on preproduction samples, first production, periodic lots, or when materials change. Also confirm which lab will be used, who pays for testing, and who pays for any retest if a sample fails.

What lead time is realistic for custom sunglasses? There is no single correct number because lead time depends on mold status, frame material, logo method, packaging complexity, and approval speed. Instead of relying on a generic promise, ask the supplier to break lead time into engineering review, sampling, material preparation, production, logo application, packing, and shipment booking. Then check whether the quote assumes an existing mold, approved artwork, and ready packaging files. A supplier that explains lead time by process step is easier to judge than one that gives only a headline number.
