Frequently Asked Questions

What is your minimum order quantity (MOQ)?
Our standard MOQ varies by product type. For most skincare products (creams, serums, lotions), the MOQ is 3,000 units per SKU. For sheet masks, it's 10,000 pieces. For hair care and body care, 5,000 units. However, we offer flexible MOQ for pilot runs and new brand launches — contact us to discuss your specific needs.
How long does it take to get samples?
Sample development typically takes 5-7 working days for existing formulations (private label). For custom ODM formulations, it takes 10-15 working days depending on complexity. Shipping to most countries takes an additional 3-7 days via DHL/FedEx. We provide real-time updates via WhatsApp throughout the process.
What is the typical production lead time?
After formula confirmation and packaging approval, production typically takes 20-30 working days for orders under 50,000 units. Larger orders (100,000+ units) may take 30-45 days. Rush orders are available for an additional fee. We maintain a 98% on-time delivery rate.
What certifications does your factory hold?
We hold ISO 22716:2007 (Cosmetics GMP), GMPC, ISO 9001:2015, ISO 14001:2015, and HALAL certification. Our facility is FDA registered (FY2024) and SGS audited. We also hold a valid Chinese cosmetics production license (粤妆20170085). These certifications ensure our products meet export requirements for US, EU, ASEAN, and Middle East markets.
Can you help with regulatory compliance for my target market?
Yes. As a CDMO partner, we provide full regulatory support. For the US market, we handle FDA registration and labeling compliance. For the EU, we assist with CPSR (Cosmetic Product Safety Report) and responsible person documentation. For China, we manage NMPA registration. We also support ASEAN, GCC, and other market-specific requirements.
Do you offer free samples?
We provide free samples of existing formulations from our catalog. For custom formulations (ODM), there is a sample development fee that is credited toward your first production order. Shipping costs are borne by the client. We can ship via your preferred courier account or our DHL/FedEx account.
What payment terms do you accept?
For new clients: 50% deposit upon order confirmation, 50% balance before shipment. For established clients (after 3+ orders): we offer flexible terms including 30% deposit with balance against B/L copy. We accept T/T (bank transfer), PayPal (for samples), and L/C for large orders. All payments in USD.
Can you develop a completely new formula from scratch?
Absolutely — this is our core strength as a CDMO. Our R&D team of 50+ scientists can develop formulations from concept to production-ready. We specialize in advanced actives (PDRN, Ectoin, exosomes, peptides) and our patented DTSS® delivery system. Development typically takes 4-8 weeks including stability testing.
What packaging options are available?
We offer comprehensive packaging solutions: standard stock packaging for fast launches, custom packaging design services, and luxury/premium packaging options. Materials include glass, airless pumps, tubes, jars, dropper bottles, and eco-friendly options (PCR plastic, bamboo, sugarcane). We can source packaging or work with your existing suppliers.
How do you handle intellectual property and formula confidentiality?
We take IP protection seriously. We sign NDAs before any project discussion. Your formulas are stored in encrypted systems with access controls. We never share client formulas between brands. For OEM clients who bring their own formula, we guarantee exclusive production rights as specified in your contract.
Do you offer product testing and stability testing?
Yes. All products undergo comprehensive testing including: microbiological testing, stability testing (accelerated and real-time), compatibility testing with packaging, preservative efficacy testing (PET), and heavy metals testing. We also offer clinical efficacy testing through our partner labs for claims support.
Can I visit your factory?
Absolutely! We welcome factory visits and encourage them. Our facility in Baiyun District, Guangzhou is easily accessible from Guangzhou Baiyun International Airport (20 min drive). Please book at least 3 days in advance so we can arrange a full tour of our cleanroom, R&D lab, production lines, and QC department. We can also assist with hotel recommendations.
What shipping methods do you use?
We offer multiple shipping options: Express (DHL/FedEx/UPS) for samples and small orders (3-7 days), air freight for medium orders (7-10 days), and sea freight for large orders (15-35 days depending on destination). We handle all export documentation including commercial invoice, packing list, COA, and MSDS. FOB Guangzhou and CIF terms available.
What is the difference between OEM, ODM, and Private Label?
OEM (Original Equipment Manufacturing): You provide the formula, we produce it. Best for brands with existing R&D. ODM (Original Design Manufacturing): We develop the formula based on your brief. Best for brands without R&D capability. Private Label: We offer ready-made formulas you can brand immediately. Fastest time-to-market. We also offer CDMO (Contract Development and Manufacturing Organization) — full lifecycle from concept to commercialization.
Do you have a product catalog I can review?
Yes, we have an extensive catalog covering 20 product categories including skincare, body care, hair care, and aromatherapy. Contact us via WhatsApp or email, and we'll send you our latest product catalog with specifications, pricing tiers, and available customization options.
What quality control measures do you have in place?
Our QC process includes: incoming raw material inspection, in-process quality checks at every production stage, finished product testing (appearance, pH, viscosity, microbiology), packaging integrity checks, and pre-shipment inspection. We operate in a 100,000-class cleanroom environment and maintain full batch traceability. Third-party SGS audits are conducted annually.
Can you help with brand strategy and market positioning?
Yes. Beyond manufacturing, we offer brand incubation services including market research, competitor analysis, product line planning, positioning strategy, and packaging design consultation. This is particularly valuable for new brands entering the market. Our team has helped launch 25+ brands across multiple markets.
