How to Write a Sunglasses RFQ for Clear Quotes

If you buy sunglasses for a brand, import program, chain, or distribution line, the RFQ is where quote comparisons usually go wrong. One factory may price acetate temples, another may assume PC frames, and a third may exclude packaging or testing. This guide shows how to write an RFQ that forces factories to quote the same build, the same compliance level, and the same delivery assumptions so you can compare numbers without guessing.

1) Start With the Decision You Need

An RFQ should not ask a factory to "quote sunglasses." That is too vague. Say what decision they are pricing: a fashion frame, a sport frame, a promotional item, or a retail SKU with compliance paperwork. The more you leave open, the wider the pricing spread. Factories will fill gaps with their own assumptions.

Start with the business use, then narrow the product class. A better opener looks like this: "men's acetate sunglasses for EU retail," "TR90 kids' sunglasses for U.S. promotional distribution," or "polarized metal sunglasses for chain-store replenishment." One sentence does a lot of work. It signals the likely frame material, lens type, test path, and packaging expectations. If the product is seasonal, say so. Seasonal programs need more time for color approval and sample rounds.

State the sales channel and destination market. A frame sold into the EU retail channel is not the same as a giveaway item. It should not be quoted the same way. If you need CE EN ISO 12312-1, say so. If the product will be sold in the U.S., ask whether the supplier has FDA registration for the relevant facility and whether the SKU is designed to align with ANSI Z80.3 where applicable. For Australia and New Zealand, call out AS/NZS 1067. If the buyer side needs REACH declarations for substances, put that in the RFQ body, not in a side email.

Also define the commercial intent. Are you benchmarking a new style, reordering a proven seller, or sourcing a cost-down version of an existing frame? Those are different quoting exercises. A reorder should preserve critical geometry and branding details. A cost-down RFQ should say exactly where substitution is allowed, such as changing a metal temple core to a simpler construction or moving from a hard case to a pouch.

LumiShades, for example, may be able to support this kind of quoting with in-house molding, cutting, machining, tinting, decoration, and QC. But that does not remove the need for a precise RFQ. Every supplier still needs the same assumptions if you want the final numbers to be comparable.

Buyer rule: If two factories can interpret your RFQ differently, they will. Narrow the scope until they cannot.

2) Lock the Product Spec Before Asking Price

The biggest quote errors come from missing specs. The price gap is often not "factory A is expensive," but "factory A priced a better product." Put the build into hard terms before you ask for numbers.

At minimum, specify the frame material, lens material, dimensions, finish, and decoration method. A complete RFQ should identify whether the frame is acetate, PC, TR90, nylon, metal, or mixed-material construction. For lenses, state TAC, PC, nylon, glass, or mirrored and tinted variants. If polarization is required, say whether the lens must be polarized or only tinted. Those are not the same cost level or performance outcome.

Size is another place where buyers lose control. Ask for lens width, bridge width, temple length, and overall front width. If you already have a target fit, include the tolerance you expect. A practical RFQ might say: lens width 54 mm ±0.2 mm, bridge 18 mm ±0.15 mm, temple 145 mm ±0.5 mm, front width 145 mm ±0.5 mm. For logo placement or printed artwork, define the location tolerance too, such as within 1 mm of the approved artwork position. Those numbers matter when multiple factories are quoting and one is assuming loose cosmetic fit while another is pricing tighter control.

Color and surface finish should be written in process terms, not marketing language. Say matte, gloss, translucent, solid, smoke, tortoise, or gradient. If color matching matters, give the Pantone reference and note whether exact match is required or whether the closest practical match is acceptable. On acetate, color depth and pattern clarity behave differently than on PC or TR90. A deep tortoise effect on acetate may look rich and layered; the same look on injection-molded resin can flatten out. Ask the factory to flag any high-risk color match before sampling.

Do not hide design ambiguity inside "similar to sample." That phrase creates expensive guesswork. If you have a reference sample, write what must stay fixed and what can change. For example: "Keep front shape, lens tint, and logo position; supplier may propose lower-cost temple construction." That gives the supplier room to engineer a lower-cost build without changing the commercial identity of the product.

• Frame material: acetate, PC, TR90, nylon, metal, or mixed construction.
• Lens material: TAC, PC, nylon, glass, or polarized variant.
• Critical dimensions: lens width, bridge, temple length, front width, and tolerance.
• Finish: matte, gloss, translucent, solid, textured, or patterned.
• Decoration: laser engraving, pad printing, hot stamping, metal logo plate, embossing, or none.
• Packaging: pouch, microfiber cloth, hard case, insert card, and carton pack-out.

3) Quote the Same Quantity Breaks

Pricing becomes useful only when the quantity ladder is the same. If one supplier quotes 100/500/1000 and another quotes 300/1000/5000, the comparison gets muddy fast. Pick the same breakpoints for every factory and choose levels that match your buying reality, not the supplier's favorite spreadsheet.

For sunglasses programs, a buyer-friendly structure is 50, 300, 1000, and 5000 pairs per style or colorway. That range usually shows the shift from setup-heavy small batches to more efficient production runs. At the low end, setup, artwork prep, color matching, and packaging configuration dominate the price. By 300 pairs, the unit cost often starts to settle. At 1000 pairs, labor efficiency and process repeatability matter more. At 5000 pairs, tool stability, line rhythm, QC discipline, and replenishment planning begin to drive the commercial result.

If a supplier's real MOQ is higher than your target, ask for the exact penalty for lower volume. Is the difference a one-time mold or setup charge, a higher unit price, or a packaging surcharge? Those are not interchangeable. A transparent quote will separate tooling, sample charges, packaging, and freight assumptions instead of bundling everything into a single "best price."

You should also ask whether the quote assumes one color per batch or mixed colors within the same order. Mixed-color runs can increase setup time, cleaning, and scrap, especially on painted or decorated components. The same applies to lens tint. A factory may quote one smoke-gray lens cheaply, then add cost when you ask for smoke, amber, and mirror finishes in the same order.

Use the quantity ladder to expose where the economics change. For example, a supplier might quote a small difference at 50 pairs but a much smaller gap at 1000 pairs because the tooling or decoration setup is already absorbed. That is why the RFQ must make every factory answer the same breakpoints.

Always ask for unit price, tooling if any, sampling charges, packaging, and freight assumptions as separate lines. If a quote bundles them, request a re-quote. A bundled number is hard to compare and easy to misread.

4) Define Materials, Finishes, and Decoration

Many RFQs fail because they say "premium finish" or "high quality materials." Those phrases do not tell a factory what to build. Use process language instead. Say what the frame body is made of, how the surface should look, and how the logo is applied.

If you want acetate, say whether you expect sheet acetate with CNC shaping, hand finishing, or another production route. Acetate usually gives a deeper visual effect and better polish depth, but it also needs more finishing work and can show edge quality more clearly. If you want injection-molded frames, specify the resin class, the surface texture, and whether a matte or glossy mold finish is required. TR90 tends to be lighter and more flexible, while PC is often cost-efficient and impact resistant, but each behaves differently in polishing, paint adhesion, and long-term appearance.

For metal components, define the base metal, plating color, gloss level, and whether exposed edges must be polished or deburred. A raw metal temple core can feel sharp or unfinished if the finishing standard is unclear. If you want a retail-ready appearance, ask for a visible surface standard in measurable terms, such as no visible burrs at a defined inspection distance under standard lighting. That kind of detail prevents the supplier from treating a cosmetic defect as acceptable.

Decoration should be specified by method and placement. "Laser engraving on left temple" is not the same as "pad print on lens corner," "hot stamp on inner temple," or "metal logo plate on right temple." Each has different tooling, cost, and failure modes. Pad printing can wear or misregister. Laser engraving is durable but depends on substrate response and depth control. Hot stamping can look crisp but may not bond equally across all materials. A metal logo plate adds thickness, assembly steps, and a risk of alignment drift.

If logo durability matters, say so explicitly. If the product will be handled frequently or sold through retail shelves, ask for a decoration method that survives abrasion and repeated folding. If you need a premium gift-box presentation, note whether the decoration must hold up on the product itself or only on packaging. That distinction affects cost a lot.

Include a finish reference whenever possible: matte black, glossy tortoise, translucent amber, brushed silver, or a specific Pantone target where the substrate allows it. Do not promise a Pantone exact match on every material. Some substrates take color well; others do not. Ask the factory to identify high-risk matches before production starts so you can approve a reasonable alternative instead of discovering a mismatch after mass production.

Practical rule: The more decoration affects touch, wear, or thickness, the more precisely it must be called out in the RFQ.

5) Put Compliance in the RFQ

Compliance should be quoted from the start. If you wait until the purchase order, you may discover the product needs different lenses, different labeling, or different documentation. That is late, expensive, and avoidable.

List only the exact standard your market needs and the proof you want supplied. For sunglasses programs, the commonly requested items are CE EN ISO 12312-1, ANSI Z80.3, AS/NZS 1067, REACH, FDA registration, ISO 9001, and BSCI. Do not ask for claims outside that list. If your market needs one of those standards, state which one applies to the SKU and what evidence must ship with the order. If you need a certificate copy, a test report, or a declaration of conformity, say so in the RFQ body.

Clarity matters on the lens side too. Sunglasses compliance is often tied to lens category, UV performance, and whether the lens is polarized, mirrored, or tinted. If the product must meet a specific transmission or protection requirement, include that in the spec. A compliance quote without product structure is incomplete because the same frame can pass or fail depending on lens build and labeling.

Ask the factory to confirm whether compliance documents are attached to the product family, the material lot, or the individual order. That distinction matters for reorders and new colorways. If a supplier is quoting a compliant build, they should be able to explain whether the test report covers the exact frame style and lens combination or only a similar product. If they cannot, you do not have a clean apples-to-apples quote.

For export buyers, this is where hidden cost appears. A supplier may give you a low number on a non-compliant lens and then re-quote once you ask for the correct test path or labeling. Better to expose that early than after sample approval, when your calendar is already committed.

6) Make Lead Time and Delivery Terms Clear

Lead time needs the same discipline as price. "Fast" means nothing. Ask for sample lead time, bulk lead time, and the exact clock start date. Does the timeline begin at artwork approval, deposit receipt, or sample sign-off? Those are different milestones, and the answer can change your launch plan by weeks.

State your shipping term in the RFQ. If you need EXW, FOB, or another term your buying team uses, spell it out. Include the destination port if applicable, carton marking rules, and whether split shipments are allowed. If you need a single consolidated shipment for retail rollout, say so. If partial release is acceptable, define the minimum acceptable split.

Some suppliers may indicate sample and bulk windows such as 7 to 10 days for samples and 25 to 35 days for bulk, but the RFQ still needs your business date. If a promotion, trade show, or retail reset depends on the order, include the final delivery target and the latest acceptable ship date. Suppliers can only commit against the date you provide.

Ask for on-time delivery history in a defined format if the supplier can provide it, and define what "on time" means. It may mean factory ship date, vessel departure, or warehouse receipt. Those are different measures. If one supplier uses ship date and another uses warehouse arrival, their performance numbers are not comparable. The same applies to sampling. Ask whether the sample clock starts from paid order, finalized artwork, or approved color standard. That detail often explains why one supplier appears faster than another.

• Sample approval date
• Deposit receipt date
• Bulk production start date
• Ex-works or FOB ship point
• Final delivery target

These five checkpoints turn a vague timeline into a contract-like timeline. They also make it easier to spot a supplier who is quoting a short lead time but quietly assuming extra days for approvals, packing, or rework.

7) Use One Template and Force a Line-by-Line Reply

The simplest way to get comparable quotes is to make every supplier reply to the same table. Do not accept a free-form email if you want a clean comparison. Put every SKU on one line and every commercial assumption in a fixed field.

Your RFQ template should include: style code, frame material, lens material, lens tint, size, color, decoration, packaging, compliance standard, MOQ, quantity breaks, sample lead time, bulk lead time, payment terms, shipping term, and quote validity. Keep the terminology identical across all factories. That removes a lot of ambiguity and makes side-by-side review practical.

Ask each supplier to confirm deviations in a separate column. If they propose a different mold route, a different temple construction, or a different packing method, it should be obvious and isolated. You want the quote to show where they are matching your spec and where they are changing it. If they suggest a lower-cost alternative, make them label it as an option rather than a substitute. That keeps the base quote clean.

The best RFQs also force a documentary reply. Ask for sample photos, material declaration, packing specification, test report reference if relevant, and lead-time assumptions. If the product is a repeat order, request that the supplier reference the prior style code and note any changes from the previous production run. That gives your team a clear audit trail.

Use a repeatable structure like this:

1. Issue one RFQ sheet per style family.
2. Attach one reference image or sample note.
3. Freeze the required spec before asking for pricing.
4. Require unit price by quantity break.
5. Require separate lines for tooling, samples, packaging, and freight.
6. Reject quotes that do not answer every field.

That sounds strict. It is. It saves money because it prevents suppliers from filling in the blanks with their own assumptions.

8) Compare Quotes Like a Buyer

Once the quotes arrive, do not rank them by unit price alone. Price is only one variable. A cheaper quote can still be worse if it uses weaker packaging, looser tolerances, slower sampling, or a less suitable compliance path.

Use a comparison sheet with these columns: unit price at each quantity break, sample lead time, bulk lead time, compliance status, packaging included, logo method, tooling charge, payment terms, and shipping assumptions. Then compare landed cost, not just ex-factory price. If one supplier includes a better hard case, more stable decoration, or cleaner carton pack-out, that can lower your real cost even if the unit price is higher.

Be blunt about trade-offs. If a supplier wants to change acetate to PC, that is not a small substitution. If they remove a hard case or downgrade the microfiber cloth, that affects retail perception and damage risk. If they stretch sample time from a short window to a much longer one, that affects your calendar. If they offer a lower quote by excluding testing or freight, that is not apples to apples. Price only matters after the build is aligned.

It helps to score quotes on four axes: spec match, compliance fit, commercial clarity, and delivery reliability. A supplier that is slightly higher but cleaner on all four often wins in practice because it creates fewer surprises after sample approval. That is especially true in eyewear, where a small change in material or finish can create a large change in appearance and acceptance.

For brands and importers, the right RFQ is a control document. It standardizes the quote. It exposes shortcuts. It gives you leverage because you can compare factories on the same sheet instead of arguing over hidden assumptions. That is the point.

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 to quote the same quantity breaks? Yes. Use identical breaks such as 50, 300, 1000, and 5000 pairs so setup cost, tooling recovery, and unit price can be compared on the same basis. If one supplier needs a different MOQ, ask them to show the surcharge or unit-price impact separately.

What compliance should I mention in a sunglasses RFQ? List only the standard your market actually needs and ask for the document type you want back. The commonly requested items are CE EN ISO 12312-1, ANSI Z80.3, AS/NZS 1067, REACH, FDA registration, ISO 9001, and BSCI. Also state whether you want a test report, certificate copy, or declaration of conformity.

Do I need to specify packaging in the RFQ? Yes. Packaging changes cost, carton efficiency, and damage risk. State pouch, cloth, hard case, inserts, inner box, and master carton requirements up front. If packaging is flexible, say which items are mandatory and which are optional.

How detailed should the decoration instructions be? Very detailed. State the method, location, color, and durability expectation. Laser engraving, pad print, hot stamping, and metal logo plates are not interchangeable. If placement matters, include a tolerance or a reference drawing.

What lead times should I ask for? Ask for sample lead time and bulk lead time separately, and state when the clock starts. A supplier can only quote a meaningful timeline if you define whether timing starts at artwork approval, deposit receipt, or sample sign-off. If you have a launch date, include it.

What should I do if two quotes look very different? Check whether the materials, packaging, compliance, tooling, or freight assumptions changed. If they did, the quotes are not comparable yet. Rewrite the RFQ so both suppliers answer the same spec, the same quantity breaks, and the same delivery terms, then ask them to re-quote.
