Frequently Asked Questions
Everything you need to know about working with GZ Cosmetics Lab. Can't find your answer? Contact us directly.
What is your minimum order quantity (MOQ)?
Our MOQ runs from 1,000 to 3,000 units per SKU depending on the product and level of customization. Most skincare (creams, serums, lotions) and body care sit in that range; some formats are higher, such as sheet masks at 10,000 pieces. We also 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 runs 35–45 days for cleansers, body and hair care, 45–55 days for serums, creams, masks and fragrances, 45–60 days for sunscreens because SPF and stability testing sit inside the timeline, and 50–70 days for freeze-dried sets. Larger orders sit at the upper end of each range. Rush options 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, certificate HBPCER20260352) and GMPC (HBPCER20260353), both issued by Intertek on 16 July 2026 and valid to 15 July 2029, plus ISO 9001:2015, ISO 14001:2015, ISO 45001, HALAL certification, and US FDA cosmetic facility registration under MoCRA (FEI 3038966060). We also hold a valid Chinese cosmetics production license (粤妆20170085) as Jiumei (Guangzhou) Biomedical Co., Ltd. The two Intertek certificates can be checked directly in Intertek's certificate database at certs.intertek.com.cn. SGS testing is supported upon request. These certifications support the documentation typically required for US, EU, ASEAN, and Middle East markets; final market compliance also depends on your formula, labelling, and registration route.
You hold both ISO 22716 and GMPC. Isn't that the same thing twice?
They overlap heavily but they are assessed against two different documents, which is why we hold both. ISO 22716:2007 is the international GMP guideline for cosmetics. Our GMPC certificate is assessed against the Cosmetic Good Manufacturing Practice Guidelines (2025) published by the US FDA. Both were issued by Intertek from the same audit, so they carry consecutive numbers and the same expiry date. The practical value is that a buyer in a market that references the ISO standard and a buyer whose importer asks about US GMP expectations can each be answered with a certificate written in the terms they already use. To be clear about what neither one is: a GMP certificate covers how the factory operates, not your specific product. It is not a product registration or approval in any market, and it does not remove your need for product notification, safety assessment or labelling compliance wherever you sell.
Is your HALAL certification enough for me to sell in Muslim-majority markets?
It is a strong starting point but it is not automatically sufficient, and you should check before assuming. Halal certification is issued by individual certification bodies, and importing countries decide which bodies they recognise — Indonesia (BPJPH), Malaysia (JAKIM), and the GCC states each maintain their own recognition lists and mutual-recognition arrangements. A certificate accepted in one market may need to be reissued by a locally recognised body for another. Certification also applies to the products and production lines within its declared scope rather than to everything we make, so a halal-certified line does not make every formula in our catalogue halal by default. Tell us your destination market early and we will confirm what is in scope and what would need re-certification, rather than letting you discover it at customs.
How do I verify your certifications myself?
Our two Intertek certificates — ISO 22716 (HBPCER20260352) and GMPC (HBPCER20260353) — can be verified by anyone at certs.intertek.com.cn, the database address printed on the certificates themselves. Our US FDA registration number (FEI 3038966060, valid to 29 July 2028) is published in full, but note that the FDA does not run a public search for cosmetic facility registrations: Cosmetics Direct is a submission portal, not a lookup tool. You can quote our FEI number to the FDA directly, or pass it to a US regulatory agent or your importer of record to confirm through their channels. Our legal entity (Jiumei (Guangzhou) Biomedical Co., Ltd., Unified Social Credit Identifier 91440101MA59F7726Y) appears on the Intertek certificates, so you can confirm that the company quoting you is the company that was audited — worth checking, because a trading company can show you a certificate belonging to a factory it does not own.
Are you FDA registered? What does that mean?
Yes. Our facility (FEI 3038966060) is registered with the US FDA under the Modernization of Cosmetics Regulation Act (MoCRA). This means we are known to the FDA and subject to inspection. It does not mean the FDA has approved or endorsed our facility or any specific product — FDA does not issue approvals for cosmetics. Registration is renewed biennially; our current registration is valid through July 2028. For brands targeting the US market, working with an FDA-registered manufacturer is a baseline regulatory requirement.
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 labeling compliance and registration guidance. 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 licensed advanced 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 Huadu District, Guangzhou is a short drive from Guangzhou Baiyun International Airport. 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 runs at four named checkpoints, which is the standard structure a cosmetics auditor will expect to see: IQC (incoming quality control) on raw materials and packaging on arrival; IPQC (in-process quality control) at every production stage; FQC (final quality control) on finished product, covering appearance, pH, viscosity and microbiology; and OQC (outgoing quality control) as a pre-shipment inspection including packaging integrity. We operate in a 100,000-class cleanroom environment and maintain full batch traceability, so any finished unit can be traced back to its raw material lots. Third-party testing through SGS is supported upon request, and our ISO 22716 (certificate HBPCER20260352) and GMPC (HBPCER20260353) certifications are subject to annual surveillance audits by Intertek.
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.
