Frequently Asked Questions
Everything beauty brand founders and sourcing teams ask us before launching private label lip collections. Got a specific formulation or custom packaging brief? Reach out directly for expert support within 12 hours.
Orders & Production
What is the minimum order quantity (MOQ) for lip cosmetics?
Our standard minimum order quantity is exactly 500 pcs per shade across all lip cosmetic categories, including lip gloss, lip mud, lip oil, lipstick, lip liner, and lip mask. This accessible threshold allows emerging beauty brands to test commercial collections without holding heavy capital or facing inventory write-offs.
How long does sample development take?
Custom lab sample development takes 7 business days from target brief sign-off. We ship physical bench samples formulated to your target viscosity, texture feel, and shade specifications via priority express air courier, delivering evaluation units directly to your product development team within 3 to 5 transit days.
What is the typical production lead time for bulk orders?
Typical bulk production lead time runs 3 to 4 weeks (15 to 25 business days) after final shade approval, component proofing, and packaging artwork sign-off. High-volume runs exceeding 50,000 units are scheduled across automated filling lines to maintain predictable dispatch dates without compromising cleanroom quality control.
Are sample fees refundable?
Yes. Lab sampling fees are 100% credited against your initial bulk purchase order invoice. When your brand transitions from prototype evaluation to commercial batch manufacturing, the entire preliminary formulation cost is fully deducted, making custom sample development effectively free of charge for launch partners.
Can I order mixed shades in one production run?
Yes, you can order multiple mixed shades in a single manufacturing run provided each distinct hue meets the baseline 500 pcs per shade threshold. For example, a 2,000-piece total production run can be split across four custom seasonal shades using standardized componentry and secondary carton specifications.
Formulation & Technology
Can I provide my own formula for contract manufacturing?
Yes. We offer custom transfer manufacturing where your proprietary formula is adapted to our high-shear vacuum homogenization vessels under strict non-disclosure terms. Alternatively, our in-house cosmetics chemists can reverse-engineer benchmarks or engineer original bespoke recipes utilizing our extensive library of certified cosmetic ingredients.
What lip cosmetics formats do you manufacture?
We engineer six core lip cosmetic formats: high-shine lip gloss, soft-blur velvet lip mud, long-wear lip tint, precision glide lip liner pencils, nourishing botanical lip balm, and intensive overnight lip mask treatments. All formulations are filled across semi-automated or automated lines tailored to specific bulk viscosities.
Do you offer vegan and cruelty-free formulations?
Yes. 100% of our lip formulations can be developed to comply with strict vegan and cruelty-free standards. We omit carmine, beeswax, lanolin, and animal derivatives, replacing them with plant waxes such as candelilla, synthetic wax blends, and vegetable squalane to earn Leaping Bunny and PETA retail certification.
What is your color matching precision standard?
We maintain an industrial color matching precision standard of Delta E ≤ 0.5 measured with dual-beam spectrophotometers under D65 daylight, cool white fluorescent, and incandescent light cabinets. This rigorous optical inspection ensures exact shade fidelity between approved lab batches, target Pantone codes, and full-scale factory production runs.
Can you develop custom active ingredients like peptides or hyaluronic acid?
Yes. We regularly enrich lip formulas with active skincare ingredients, including palmitoyl tripeptides, sodium hyaluronate microspheres, ceramide complexes, botanical squalane, and oil-soluble vitamin C. These active ingredients provide measurable clinical benefits like deep barrier repair, moisture retention, and plumping effects supported by ingredient supplier efficacy data.
Compliance & Certifications
What certifications does your facility hold?
Beautychain Limited operates cleanrooms certified under ISO 22716:2007 and GMPC guidelines for cosmetic manufacturing. Our manufacturing facility maintains active US FDA establishment registration, follows strict Good Manufacturing Practice protocols, and passes regular on-site third-party quality assurance audits by multinational consumer goods assessment firms.
Do you provide FDA MoCRA compliance documentation?
Yes. We supply comprehensive documentation packages aligned with US FDA MoCRA regulations. This includes cosmetic product listing sheets, mandatory facility establishment registration records, fragrance allergen breakdowns, batch safety attestations, and raw material ingredient disclosures required for commercial retail and marketplace distribution in the United States.
Can you handle EU CPNP notifications?
Yes. We prepare turn-key regulatory dossiers required for European Cosmetic Product Notification Portal (CPNP) filing. Our team provides complete Product Information Files (PIF), full INCI quantitative declarations, safety data sheets (MSDS), toxicological assessments, and CPSR support to ensure frictionless customs entry throughout the European Union and UK.
What heavy metal testing standards do you follow?
Every production batch undergoes strict ICP-MS testing against international safety thresholds: Lead < 10 ppm, Arsenic < 3 ppm, Mercury < 1 ppm, and Cadmium < 3 ppm. Detailed Certificates of Analysis (COA) verifying these heavy metal parameters and microbial purity (< 100 CFU/g) accompany each outbound shipment.
Do you perform stability testing?
Yes. Our standard laboratory protocol includes 6 freeze-thaw thermal stress cycles over 14 days ranging from -15°C to +45°C, coupled with 3-month accelerated stability chambers at 40°C with 75% relative humidity. This validates emulsion stability, phase separation resistance, component compatibility, and shelf-life integrity before market release.
Logistics & Customer Support
What shipping methods do you offer?
We provide end-to-end global shipping solutions including express air courier (3 to 5 business days), air freight forwarding (5 to 7 business days), and ocean container freight (25 to 35 transit days). We support DDP, DAP, and FOB terms, managing complete customs export declarations for your port of destination.
Do you provide private label packaging design services?
Yes. Our industrial packaging engineers deliver complete structural and graphic design services. We provide precision dieline files, 3D photorealistic renderings, label layout optimization, and hot-stamping, silk-screen, or UV coating specifications, guiding your visual identity from initial creative concept to high-speed commercial printing readiness.
What payment terms do you accept?
Standard payment terms are T/T 30% deposit upon formal proforma invoice confirmation to initiate component sourcing and batch scheduling, with the remaining 70% balance payable after pre-shipment quality inspection approval. For enterprise purchase orders exceeding $50,000 USD, we accept irrevocable documentary letters of credit (L/C).
Can I visit your factory?
Yes. We warmly welcome clients to visit our certified Shenzhen production facility for technical audits and batch consultations. Alternatively, if travel schedules are constrained, we coordinate live HD video factory walkthroughs, allowing your product team to inspect cleanrooms, automated filling machinery, and QC testing laboratories in real time.
What is your defect rate guarantee?
We maintain an industrial defect rate guarantee below 0.3% backed by an unconditional 100% replacement warranty. Every bulk unit undergoes in-line optical checks and final pre-shipment AQL 1.5 standard audits; any verified functional or cosmetic defect is remanufactured or credited without commercial dispute.
