How to Communicate with makeup brush Manufacturers about the customized brush color

 The bristles, metal ferrules and handles of makeup brushes adopt different coloring processes. When communicating custom color requirements with a makeup brush factory, customers should classify each component, confirm  official color standards and seal approved samples to drastically reduce rework caused by color deviation.

 

Color Codes & Reference Standards

1. Only use Pantone C solid color cards and special metallic color cards to confirm the colors. Photos and screenshots are for reference only and cannot be used as inspection criteria.
2. Send physical samples of existing makeup brushes directly to the makeup brush factory; which has far higher color accuracy than color codes alone.
3. Distinguish coloring differences by material: anodized aluminum ferrules, painted copper ferrules, water-coated wooden handles and fiber bristles cannot share the same color reference standard.

 

Makeup Brush Components

1. Metal Ferrules: New custom colors require dedicated dye tanks, leading to higher MOQ per single color. Matte, glossy and satin finishes show drastically different appearances even for the same Pantone code, so surface finish must be clearly specified. Specify acceptable ΔE color tolerance in advance.
2. Handles: Solid wood cannot achieve highly saturated bright hues. Integrally injection-molded colors suit large orders, while spray painting is recommended for small batches. Verify the paint layer is wear-resistant and won’t expose the base after repeated wiping.
3. Bristles: Synthetic fibers cannot be freely dyed into brand-new custom shades. Fine-tune colors based on the factory’s in-stock bristle shades first. Mandate strict dry and wet rub color fastness to prevent color transfer onto skin or powder pans.

 

Sampling & Sample Sealing

1. Produce separate samples for ferrules, handles and bristles first, then assemble full brush samples for step-by-step verification to cut waste.
2. Once approved, customers and makeup brush manufacturers sign and seal physical samples, with written confirmation that mass production strictly follows these signed samples.
3. Mass production shall never commence before pre-production samples are fully approved.

 

Inspection Lighting Conditions

Color comparison inspection must be carried out under D65 standard white light. Ordinary indoor yellow or warm lighting causes inaccurate color judgment.
 
Avoid vague phrases such as “roughly ” or “similar” during  customizing makeup brush colors. Finalize requirements via Pantone codes, production processes, tolerance values and sealed sample paperwork to stabilize color quality from the start and ensure smooth order fulfillment.

Why makeup brush handles painting crack?

 Many clients may encounter a common trouble: some wooden handles of newly delivered makeup brushes develop cracked paint or wood bodies after storage or use. Cracking severely downgrades product texture and triggers after-sales returns & replacements. Makeup brush manufacturers should know the causes and make improvements during makeup brush production.

 

Unqualified moisture content of wood (root cause)

If the raw wood for handles is not thoroughly dried, plenty of moisture remains inside. After delivery, the wood shrinks heavily under dry air or heating. The paint film lacks enough flexibility to follow the shrinkage, so it gets stretched and cracked; in severe cases, the wood body splits too. Big gaps of temperature and humidity between worldwide countries, long sea transportation and unstable storage humidity will worsen this issue greatly.

Non-standard painting procedures

1. Lack or thin sealing primer: Without primer barrier, internal wood moisture evaporates continuously and breaks the topcoat into fine cracks.
2. Over-thick single topcoat layer: The paint dries unevenly from surface to inner layer, forming strong shrinkage stress that causes cracking over time.
3. Poor sanding with dust or grease residue weakens paint adhesion; slight wood deformation will lead to peeling and cracks easily.

Low-flexibility paint material

Cheap paint is stiff and brittle with poor stretch capacity. Makeup brush handles require special high-elastic paint. Improper thinner mixing ratio also makes the coating fragile and crack-prone.

Hidden flaws on wooden handles

Tiny turning scratches or invisible micro-cracks on handle are covered up by paint during production. Alternating hot/cold temperatures or slight knocks and vibration during storage and use will expose these cracks later.

Harsh storage and usage conditions

Long-term direct sunlight near windows, placement beside heaters, rapid drying after contact with water, or direct air conditioning airflow create drastic humidity & temperature changes, repeatedly straining wood and paint to speed up cracking and aging.
 
Makeup brush manufactures should keep strict drying standards, standardized multi-layer thin coating, high-flexibility special paint, and constant-temperature moisture-proof storage, which can greatly cut cracking risks, stabilize product quality and reduce after-sales complaints.

How Makeup Brush Factory Conducts In-house Safety Inspection

 As a professional makeup brush manufacturer, Kingyin implements full-process self-inspection from raw material incoming to finished goods delivery to guarantee hygiene and product safety. With economical testing tools for routine quality checks, we proactively eliminate hidden risks including microbes, chemical residues and material defects at source to avoid compliance issues and meet Chinese and overseas regulatory standards.

 

Microbiological Hygiene Test (Rapid Test Strips)

Soak and agitate bristles in sterile water, then incubate microbial test strips at 37°C for 24 hours. Products containing pathogenic bacteria shall be rejected, and batches with excessive total bacterial count are disqualified. Animal hair batches undergo priority sampling inspection.
 

Simplified Chemical Screening

1. 365nm UV Lamp Check: No fluorescence on bristles confirms free of fluorescent whitening agents;
2. Cold Water Immersion Test: Soak brushes in ambient-temperature water for 30 mins; qualified items feature no color bleeding or pungent odor from formaldehyde or inferior solvents;
3. pH Test Strip: Aqueous extract pH value is controlled within 5.0~8.5;
4. Simplified Salt Spray Test: Ferrule soaked in salt water for 24 hours with no rusting or coating precipitation.

 

Physical Safety Inspection

· No color transfer after 50 times of dry cotton cloth rubbing;
· Hair fallout meets national standard via rolling compression test;
· Smooth handles free of burrs and adhesive without harsh smell.
· 

Incoming Material Control

Original MSDS and compliance certificates are required for bristles, adhesive and metal accessories. Synthetic fiber materials are verified against REACH regulations while animal hair is accompanied by quarantine certificates.

 

Third-party Submission

Any batches failing internal inspection will be sent to CMA-accredited third-party labs for precise testing on heavy metals, azo dyes and formaldehyde.

Why Do Makeup Brush Manufacturers Refuse Orders of 50 to 100 Pieces?

Many new brands hope to customize 50 to 100 sets of makeup brushes for market testing, yet most makeup brush manufacturers refuse such orders. Since makeup brushes are partially handmade,why makeup brush factories turn down small-batch orders?

There are 3 core reasons why makeup brush manufacturers do not accept orders of 50 to 100 pieces: excessively high fixed costs, complicated production line changeovers, and high-end craftsmanship that cannot adapt to small-batch production. Such orders result in financial losses and disrupt the overall production schedule.

 

Cost Analysis: Small orders yield no profit at all

High molding cost

1. Custom makeup brush handles and special-shaped brush heads require special molds, which has high cost

2. When allocated to 50 pieces, the mould cost per unit reaches hundreds of RMB. For an order of 10,000 pieces, the cost per unit drops to just a few RMB.

Minimum Order Quantity (MOQ) for raw materials

1. Suppliers set strict MOQs for Nylon, PBT, aluminum ferrules and wooden handles. For example, raw materials start at 500kg, and handles at 1,000 pieces.

2. Makeup brush factories have to purchase scattered materials at a higher price for small orders, pushing raw material costs up by over 50%.

Exorbitant machine setup and labor costs

1. Production processes including fiber drawing, injection moulding, bristle trimming, brush assembling, shaping and logo printing require machine adjustment, line cleaning and trial production whenever switching orders. The whole process takes several hours to half a day.

2. For an order of 50 pieces, the setup cost even exceeds the total order value. Costs become reasonable only for orders of 1,000 pieces or more.

Inevitable yield loss

The initial batches are trial products, with a rejection rate of 10% to 20%. For small orders, all such losses have to be covered by the mere 50 finished pieces.

 

Production Line & Scheduling: Small orders disrupt overall efficiency

1.The entire production process, including fiber drawing, shaping, sorting, bristle planting, trimming, quality control and packaging, operates as an integrated assembly line for mass production.

2.Small orders of 50 pieces will slow down the whole line and lead to frequent production changeovers, cutting overall productivity .

3.With limited production capacity, makeup brush factories give top priority to long-term orders ranging from 500 to 5,000 pieces. Orders of just 50 pieces bring slim profits and low priority, so they are either scheduled at the very end or declined entirely.

 

Makeup brush General Rules: Minimum Order Quantity (MOQ) starts from 500 to 1,000 pieces

· Standard blank makeup brushes (no logo, regular design): MOQ 300–500 pieces per item.

· Customized makeup brushes (custom handle color, logo, special bristle style): MOQ 1,000–2,000 pieces per item.

· Premium material brushes (antibacterial): MOQ 2,000–3,000 pieces per item.

· Orders of 50–100 pieces fall under sampling and trial production, rather than mass production. Makeup brush factories will not accept such orders at standard mass-production prices.

 

 

Kingyin MOQ Policy:

· Mass production MOQ: 1,000 pieces per item (to ensure consistent quality and cost-effectiveness).

· Sample orders: 10–20 pieces. Sample fees will be fully refunded upon formal bulk order placement.

· Small trial orders: Minimum 300 pieces per item with unit price surcharge; lead time: 6-8 weeks.

· Mass orders of 50–100 pieces are not accepted, as they conflict with our quality standards, cost structure and production efficiency requirements.

 

Why Kingyin makeup brush over cost is lower than Southeast Asian counterparts

 In recent years, due to tariffs and other issues, many makeup brush brands have begun shifting their orders to Southeast Asian OEM factories, and many makeup brush factories have also moved their production lines to Southeast Asia to reduce costs. However, the reality is often less than ideal.

In fact, established makeup brush OEM factories like Kingyin have lower overall costs than their Southeast Asian counterparts. This is because China's mature supply chain, long-term technological accumulation, and stable and efficient operations offset the apparent difference in labor costs, resulting in cost advantages in materials, yield, delivery time, and management. Southeast Asia suffers from low apparent wages, high hidden costs, weak supporting facilities, a shortage of skilled workers, poor yield, and unstable delivery times; while established OEM factories like Kingyin have a closed-loop supply chain, a large pool of skilled workers, mature technology, high yield, accurate delivery, and long-term stability—therefore, the overall cost is actually 12%–18% lower.

Supply Chain:

Core Materials for Makeup Brushes: Bristles (synthetic/Animal Hair), Ferrule (aluminum/copper), Wooden/Plastic Handles, Glue, Packaging.

Kingyin:
1. Bristles: in-house production, stable quality and controllable cost.
2. Ferrules: same-day order, next-day delivery, prices 15%-20% lower than Southeast Asia.
3. Handles: supply within 50km,complete specifications, low minimum order quantity, stable delivery time.
4. Glue/Packaging: Complete supply within 50km, no long-distance logistics, no tariffs, no port congestion.

Southeast Asia (Vietnam/Thailand/Indonesia)
1. 70% of raw materials, high-end aluminum ferrules, and specialized adhesives are imported from China. Sea freight takes 7-14 days, and with tariffs, logistics, and demurrage fees, material costs are directly 8%-12% higher.
2. Incomplete local supply chains, numerous outsourcing projects, unstable quality, and uncontrollable delivery times frequently lead to production stoppages due to material shortages.

Cost difference: 5%-8%

Labor cost:

Makeup brush production is a semi-manual, semi-automated process, with bristle implantation, combing, and trimming highly dependent on skilled workers.

Monthly Salary (2025)
Kingyinn: Approximately US$600–700
Vietnam: US$300–450; Thailand: US$400–500

However, Southeast Asia has extremely high hidden labor costs.
1.Lack of Skilled Workers: The Southeast Asian makeup brush industry started late, with less than 20% of workers having 3+ years of experience; Kingyin has more than 60% with 5+ years of experience, and per capita productivity is 1.4–1.6 times that of Southeast Asia.
2. High Turnover Rate: Vietnam's annual turnover rate is 30%–40%, leading to repeated recruitment, training, and production stoppages, with an average annual loss per worker ≈ 2 months' salary.
3. High Training Costs: Bristle implantation/trimming training takes 2–3 months; the yield rate for newcomers in Southeast Asia is only 60%, while Kingyin is 95%+.
4. High management costs: Requires on-site Chinese/Korean technical support; translation, supervision, and cross-cultural management incur high costs.

Overall labor costs (including efficiency, turnover, and management): 3%–5% higher in Southeast Asia than in Kingyin.

Craftsmanship and Yield Rate:

Kingyin
15+ years of professional makeup brush manufacturing, ISO9001/BSCI certified, 38 quality inspections, rework rate <2%.
Standardized process for bristle implantation, combing, and trimming + skilled handcrafting, yield rate 92%–95%.

Southeast Asian makeup brush Factories
Most are new factories (less than 3 years ), with immature processes, rework rate 8%–15%, scrap rate 3–5 % higher.
Workers lack understanding of “bristle tip alignment and powder picking ability,” resulting in a yield rate of only 70%–80% for high-end makeup brush orders.

Yield Rate + Scrap + Rework Cost Difference: 2%–4%

Energy, Logistics, and Taxes:

Energy: China's industrial electricity price is stable at 0.7–0.8 RMB/kWh; Vietnam experiences frequent power rationing, and diesel generators are expensive, resulting in 2%–3% higher energy costs.

Logistics: The shenzhen/guangzhou ports offer 24-hour direct shipping to Europe and America, with no transshipment or port congestion; Southeast Asian ports are congested, sea freight takes 3–7 days, and express air freight is costly.

Taxes: Southeast Asia's "4-year exemption, 9-year half-tax" policy mainly targets large export projects, offering limited benefits to small and medium-sized enterprises; compliance costs and policy change risks are also high. China's tax system is transparent, stable, and offers strong long-term certainty.

Overall Energy + Logistics + Tax Difference: 2%–3%

Quality and Delivery Penalties:

• Kingyin: On-time delivery rate 98%+, very few expedited air freight orders, very few customer penalties.
• Southeast Asia: Delivery delays are common (30% of orders are delayed by 7+ days), frequent rework leads to air freight penalties, fines, and reputational damage, with an average additional cost of 1%–2% per order.

Summary:

 Supply chain support (materials + logistics + inventory): 5%–8%
 Overall labor cost (efficiency + turnover + management): 3%–5%
 Yield rate + scrap + rework: 2%–4%
 Energy + taxes + delivery penalties: 2%–3%
 Total: 12%–18%

Why makeup brush wooden handle is heavier than plastic handle?

During the customization of makeup brushes, users may observe that, for identical handle dimensions, brushes with birch wood handles tend to be heavier than those with plastic (ABS or PP) handles.  
 
This observation appears counterintuitive, as the theoretical density of birch wood (~0.65 g/cm³) is lower than that of ABS or polypropylene (PP), which typically ranges from 0.9 to 1.0 g/cm³.  That is because most low and mid-range plastic brush handles are made via hollow injection molding with internal cavities, resulting in an overall density far below 1 g/cm³. In contrast, wooden handles are generally solid wood , hence heavier than lightweight plastic handles.
 
Therefore, during communicating with the makeup brush manufacturers, customers should firstly specify the exact material of the makeup brush handles.

Does the weight of makeup brushes affect the makeup result?

Yes, and the effect is quite significant. 
For makeup brushes of the same size: Heavy birch wood handles are heavier than lightweight hollow plastic handles. Their feel directly changes your makeup techniques and final looks.

1. Core differences caused by weight

① Heavy handle (solid birch wood handle)

It has natural downward gravity, so you don’t need to press hard on purpose. It picks up powder evenly, delivering smoother powder pressing, better skin adherence and softer blending. It ensures steadier application for eyeshadow, blush and contour without shaky hands.
Suitable for: Daily light makeup, delicate blending and makeup beginners.
Disadvantage: Slightly tiring to hold for a long time.
 

② Light handle (hollow plastic handle)

You have to fully control pressure with your own hand strength. It tends to cause excessive application, powder fallout and cakey makeup. It features high flexibility, ideal for fine detailing and outlining with angled brushes.
Suitable for: Experienced makeup users for precise shaping and partial highlighting.
 

2. Specific impacts on makeup effects

· Eyeshadow: Heavy handles deliver easy color payoff and soft gradients with gentle sweeps; light handles easily lead to heavy application and messy eye makeup.
· Blush & loose powder: Heavy handles press powder closely to skin for a natural non-caked finish; light handles tend to apply too much powder and create an unnatural look.
· Contour: Heavy handles create seamless transitions; light handles easily leave harsh dark lines.
· Makeup staying power: The gentle natural weight helps powder adhere better to skin for longer-lasting makeup.

3. Tips

· Beginners & those who prefer soft natural makeup → Choose makeup brushes with solid birch wood handles
· Pros & those doing bold makeup, cut crease looks or precise lines → Choose lightweight plastic-handled brushes
· Prioritize heavy handles for eye blending brushes; opt for light handles for angled detail brushes
