What is the Minimum Order Quantity (MOQ)?

When developing custom eyewear, Minimum Order Quantity (MOQ) is one of the first questions brands ask — and one of the least understood.

At Wooly Eyewear, MOQ is not an arbitrary number.
It is determined by material behavior, production efficiency, tooling setup, yield rate, and quality control risk.

This article explains why different materials require different MOQs, and what challenges manufacturers face behind the scenes — so B2B buyers can make smarter design and material decisions.

 

For custom branded sunglasses, our standard MOQ starts at 300 per model per color.

What Does MOQ Mean in Eyewear Manufacturing?

MOQ (Minimum Order Quantity) is the lowest production quantity required to:

  • Maintain stable quality

  • Control defect rates

  • Offset tooling and setup costs

  • Avoid excessive material waste

In eyewear production, MOQ is affected by:

  • Frame material (PC vs TR90)

  • Lens structure (PC vs PC Polarized vs PCPL)

  • Color consistency requirements

  • Secondary processes (rubber overmolding, coatings, laminations)

 

 

Frame MOQ by Material

PC Frame MOQ

300 pcs per style per color

TR90 Frame MOQ

600 pcs per style per color

Why Is TR90 MOQ Higher Than PC?

 

Although PC and TR90 are both common eyewear materials, their manufacturing processes are fundamentally different.

1. Material Processing Stability

  • PC (Polycarbonate)

    • High injection stability

    • Shorter cycle time

    • Lower deformation risk

    • Easier to control wall thickness

  • TR90

    • Nylon-based flexible polymer

    • Requires precise temperature, pressure, and cooling control

    • Higher risk of warpage and dimensional variation

    • Longer cycle time per frame

 For TR90, small production runs increase inconsistent flexibility, fit, and shape retention, which directly affects product quality.

 

2. Mold Setup & Yield Rate

  • TR90 molds require:

    • Longer mold warm-up time

    • More trial runs to stabilize flexibility

    • Higher reject rate during initial production

If production volume is too low, the cost per usable frame becomes disproportionately high, making small batches inefficient and risky.

 

3. Color Consistency

TR90 pigments:

  • Are harder to disperse evenly

  • Are more sensitive to temperature changes

  • Show more visible color shift between batches

Larger MOQ ensures:

  • Stable color tone

  • Reduced batch-to-batch variation

  • Fewer color complaints from brands

 

Lens MOQ by Material

PC & TAC Lenses

300 pcs per style per color

PC Polarized / PCPL Lenses

600 pcs per style per color

 

Why Is PCPL MOQ Higher Than Standard PC or TAC?

Polarized lenses are not just tinted lenses — they are multi-layer optical systems.

 

1. Complex Lamination Structure

PCPL lenses require:

  • PC lens substrate

  • Polarized film

  • Adhesive bonding layer

  • Controlled heat and pressure lamination

Each layer must align precisely to avoid:

  • Optical distortion

  • Polarization angle deviation

  • Delamination

Small production volumes:

  • Increase material waste

  • Increase scrap rate during lamination setup

  • Raise per-unit failure risk

 

2. Higher Setup Loss

During PCPL production:

  • Polarized film alignment requires trial runs

  • Initial lamination often results in rejected lenses

  • Coating adhesion must be validated before mass production

With low quantities, setup losses can exceed usable output, making production inefficient.

 

3. Optical Quality Control

Polarized lenses require:

  • Polarization efficiency testing

  • Axis alignment checks

  • Light transmission consistency

These QC processes are time-intensive, and MOQ ensures:

  • Cost-effective inspection

  • Stable optical performance

  • Fewer post-delivery issues

 

Why Is Rubber Color MOQ So High?

Rubber components (nose pads, temple tips, grip inserts) may look small — but they are one of the most challenging parts to color-match.

1. Dedicated Color Mixing

  • Custom rubber colors require:

    • Dedicated pigment formulation

    • Full material mixing batch

    • Separate storage and cleaning afterward

Once mixed, unused rubber cannot be reused for other colors.

 

2. Tool Cleaning & Contamination Risk

  • Rubber molds are highly sensitive to color residue

  • Changing colors requires:

    • Full mold disassembly

    • Chemical cleaning

    • Test shots before production

For small quantities, cleaning cost exceeds production value.

 

3. Color Consistency Risk

Small rubber batches often result in:

  • Shade variation

  • Gloss inconsistency

  • Texture mismatch

Higher MOQ ensures:

  • Stable color tone

  • Consistent grip feel

  • Professional finish across the full order

 

 

Special or Custom Rubber Components

Custom Color Rubber Parts

MOQ: 1200 pcs per style per color

 

How MOQ Protects Both Factory and Brand

MOQ is not about limitation — it is about risk management.

For factories:

  • Prevents excessive scrap

  • Ensures efficient production

  • Maintains consistent quality standards

For brands:

  • Reduces defect risk

  • Improves color and fit consistency

  • Avoids hidden cost from rework or replacements

 

Final Thoughts: Choosing the Right MOQ Strategy

Understanding MOQ helps brands:

  • Choose the right material for their launch stage

  • Balance budget vs performance

  • Plan scalable product development

At Wooly Eyewear, we always help brands:

  • Optimize MOQ for samples and pilot runs

  • Select materials suitable for low-volume launches

  • Scale production smoothly as demand grows

MOQ is not a barrier — it’s a foundation for quality.
