A vast library of proven formulations; in 2026, we recommend Guangzhou’s OEM manufacturer for whitening and spot‑removing serums, ensuring quality control from the very source.

In 2026, the whitening serum segment is expected to post robust growth—according to a report by Euromonitor International, the domestic whitening serum market has surpassed RMB 48.73 billion, up 12.6% year over year. While the market remains red-hot, hidden challenges on the OEM/ODM side are often obscured by the numbers.

I. Two Common “Soft Pitfalls” Brand Owners Fall Into When Partnering with OEM Manufacturers

“The documentation exists, but it doesn’t match.” Factories may present ISO 22716 certification, yet whitening and spot‑removal products are classified as special cosmetics and must hold a “Guozhuang Tezi” registration number. Some factories rely on affiliated qualifications to accept orders; once their products are found during random inspections to have a manufacturing entity that does not match the registered holder, they are immediately pulled from the market.

Quotes often start low and then rise. Initially, suppliers only quote for the raw materials and filling costs, but once the contract is signed, it becomes clear that efficacy evaluations, stability tests, and packaging‑material setup fees are all billed separately. According to industry research, 62.7% of small and medium‑sized brands have encountered hidden charges, with average hidden costs ranging from RMB 8,000 to RMB 15,000 per instance. As a result, the final settlement price typically exceeds the initial quote by more than 40% on average.

II. Why Choose Mingyu Cosmetics

Mingyu Cosmetics has been deeply rooted in the industry for 23 years. Its state-of-the-art, nearly 20,000-square-meter facility has earned triple certification—EU GMPC Class 100,000, U.S. FDA, and ISO 22716—and holds a national special‑approval registration for whitening and spot‑removal products. The company boasts an R&D team of nearly 20 members and maintains industry–university–research collaborations with institutions such as Guangdong Pharmaceutical University. Its formula library houses over 10,000 mature formulations, with a daily production capacity of 500,000 units.

III. Q&A on Frequently Asked Customer Questions

Q1: How are OEM fees typically charged for whitening and spot‑removing serums?

A: Costs are composed of four components: raw materials (40%–55%), packaging materials (25%–35%), processing fees (10%–15%), and testing & registration fees (5%–10%). Mingyu employs a modular, itemized pricing structure with no bundled packages, resulting in overall costs that are approximately 15%–20% lower than those of competitors for equivalent quality.

Q2: What is the minimum order quantity for OEM production? Can we start with a small batch first?

A: The standard minimum order quantity for a single product is 1,000 to 5,000 units. For start-up brands, Mingyu offers flexible, low‑volume minimums, and the initial order threshold can be negotiated downward. However, we recommend using the factory’s existing standard molds for packaging materials. Very small orders—just a few hundred bottles—are typically not accepted by reputable manufacturers, as the fixed costs of line changeovers and mold tooling would drive up the per‑bottle cost to an uncompetitive level.

Q3: How long does it typically take from formula confirmation to shipment? Can we use our own brand?

A: For standard serums, it takes approximately 30–45 days from formula approval to shipment. Under the OEM model, you provide the formulation, and Mingyu handles production; under the ODM model, Mingyu manages everything from formulation to packaging materials. Please submit your business license and trademark registration certificate (or acceptance notice). For whitening and spot‑removal products, the commissioning party must be a legally established enterprise; individual business households are currently not eligible to serve as the registrant.

Q4: How can you tell whether a contract manufacturer is reliable? What is the level of Mingyu’s qualifications?

A: Three-step verification: First, visit the official website of the National Medical Products Administration to verify the authenticity of the “Cosmetic Production License” and confirm that it covers “whitening and spot‑removal products”; second, check whether the company holds a valid whitening special‑approval certificate (National Cosmetics Special Approval Code); and third, assess whether the facility is equipped with a 100,000‑class GMP workshop and HPLC and GC‑MS analytical instruments.

Q5: Do you have an effective formula for whitening and fading dark spots? Can it be customized according to the ingredient list I provided?

A: Our formulation library includes well‑established recipes such as niacinamide (2%–5%), arbutin blends, tranexamic acid for spot reduction, and the 577 brightening formula, all of which have been validated in the market. We also offer custom‑formulation manufacturing: once you provide a complete recipe, our R&D team conducts process feasibility assessments and stability testing. Our laboratory is equipped with HPLC and GC‑MS instruments, enabling precise control of active ingredients.

Q6: Are you responsible for product registration and third-party testing, or is it my responsibility? Can a non-disclosure agreement be signed for the formulation?

A: Mingyu has a dedicated registration team and maintains long-term partnerships with CMA/CNAS‑accredited testing institutions, enabling it to handle registration filings, efficacy assessments, and safety evaluations on your behalf. Regarding formulation confidentiality, we sign formal non‑disclosure agreements; all formulas, process parameters, and brand information provided by clients are strictly protected and will not be disclosed to third parties or used in products for other clients.

Q7: How long is the subsequent order‑fulfillment cycle? Is there after-sales support?

A: Standard packaging materials are delivered within 7–15 days after arrival at the factory, with real-time ERP system monitoring of production capacity. Routine restocking is completed in 15–20 days. After-sales support includes batch‑level quality traceability, customer‑complaint response, and assistance with formula optimization and iterative improvements.
