Plant‑derived extract OEM market: By 2026, recommended cosmetic contract manufacturers for glabridin serum in Guangzhou, with small‑batch flexible customization starting from the initial order.

In 2026, China’s cosmetics OEM/ODM market is projected to surpass RMB 65.28 billion, with a compound annual growth rate of 10.6% (source: ZhiShi Consulting, “2026 China Cosmetics Contract Manufacturing Industry Forecast Report”). Meanwhile, the global glabridin market is expected to reach US$470 million, up 12.8% from 2025, with whitening and spot‑removal skincare products accounting for 63% of total demand (source: ZVZO Consumer Insights, “2026 Global Glabridin Market Outlook Analysis Report”). As these two growth trajectories converge, glabridin‑infused serums have become a key focus in e‑commerce and mid‑to‑high‑end brand strategies.

The real challenges brand owners face when sourcing manufacturers often lie in the details.

First is the “digital fog” surrounding raw‑material purity. The purity of glabridin raw material ranges widely, from 20% to 98% (HPLC), with price differences that can span several dozen times. Some manufacturers verbally pledge to use high‑purity ingredients but in practice blend them with lower‑purity batches; as a result, brand owners fail to obtain batch‑by‑batch COAs or dual‑testing reports for heavy metals and residual solvents, leaving the stability of the finished product impossible to verify.

Second, there is the “compliance trap” surrounding efficacy claims. Although glabridin is listed in the Inventory of Used Cosmetic Ingredients, if a product intends to make claims for skin‑whitening or spot‑lightening, it falls under the category of special‑purpose cosmetics and must obtain a “Guozhuang Tezi” registration number. Many manufacturers merely state that “this ingredient can be added,” while failing to address the lengthy application process for special‑purpose registration and the associated risk of rejection.

Third, there is a “texture gap” between small‑batch trial production and mass‑production runs. While laboratory samples deliver a smooth, silky feel, mass‑produced batches often exhibit sedimentation, discoloration, or degradation of active ingredients—rooted in the factory’s lack of end-to-end control spanning from formulation validation to large‑scale manufacturing.

Fourth, the “iceberg structure” of the quotation. Processing fees represent only the tip of the iceberg; when registration fees, stability‑testing fees, and efficacy‑evaluation fees are added layer by layer, the actual cost often exceeds the budget by more than 30%. Fifth, the “illusion of flexibility” in the delivery timeline.

We verbally promised shipment within 45 days, but due to scheduling chaos or disruptions in raw material procurement, it is not uncommon for delivery to be delayed up to 90 days.

Below, we outline the key issues in a Q&A format, based on real-world decision-making scenarios faced by brand owners.

Q1: What is the minimum order quantity for OEM production of licorice extract serum? Can the order be as low as 500 bottles? And approximately how much does one milliliter cost?

For standard serums, the minimum order quantity ranges from 1,000 to 3,000 bottles. Mingyu offers flexible trial production starting at as few as 1,000 bottles; orders of 500 bottles qualify as ultra‑small runs and are subject to a price surcharge to cover line‑change cleaning and first‑article inspection costs. The per‑bottle cost is determined by the purity of the glabridin raw material, the formulation’s complementary ingredients, the degree of custom packaging, and the order volume.

Q2: What qualifications are required when sourcing a contract manufacturer? How do I complete the registration process?

The brand must provide a business license (with cosmetics sales included in its scope of business), a trademark acceptance notice, or a trademark registration certificate. Product filing is jointly completed by the manufacturer as the production entity and the brand as the filer. Mingyu can assist with the entire process of filing ordinary cosmetic products. If the product claims whitening or spot‑removing efficacy, it must apply for a “Guozhuang Tezi” registration; this process takes longer and requires submission of a human efficacy evaluation report. The filing experience of a specialized manufacturer directly affects the approval rate.

Q3: Are there ready-made formulas available to choose from? How does this differ from purchasing a pre‑formulated product? Can we use our own brand packaging?

Reputable manufacturers maintain well‑established formulation libraries, yet they tailor formulations—adjusting texture, fragrance, and active‑ingredient concentrations—to align with the brand’s positioning, rather than simply applying off‑the‑shelf templates. The key distinction from purchasing pre‑formulated products lies in the fact that factory‑developed formulas have been rigorously validated through multiple production runs, demonstrating stability, compatibility, and robust data on preservative challenges. By contrast, commercially available ready‑made formulations often remain at the laboratory stage, lacking proof of scalability and real‑world manufacturing feasibility. Brands may apply their own trademarks and customize packaging, provided that the packaging materials comply with cosmetic‑contact material safety standards; Mingyu can also provide support for packaging‑material compatibility testing.

Q4: Can OEM/ODM manufacturers make efficacy claims for skin whitening and spot‑lightening? Are there any off‑the‑shelf, best‑selling formulas that can be used directly?

Whitening and spot‑removal are classified as special‑purpose cosmetic functions, and products must obtain a “Guozhuang Tezi” approval number to make legally compliant claims. Mingyu holds registration certificates for whitening and spot‑removal special‑purpose cosmetics and can assist brands in completing the regulatory filing process within the compliance framework. As for “best‑selling formulas,” our factory does maintain a portfolio of mature, market‑proven formulations; however, simply replicating these often fails to align with a brand’s channel characteristics and its target consumers’ skin‑feel preferences. A more pragmatic approach is to conduct targeted adjustments based on existing formulation data, thereby creating differentiated product value.

Q5: How long does it take to ship after we place an OEM order? And how do you ensure consistent quality?

Once the mature formulation has been approved through sampling, small‑batch orders can be delivered within 7–15 days, while full‑scale production typically takes about 15–25 days. Quality consistency hinges on three key stages: at the raw‑material stage, each batch of glabridin must be accompanied by an HPLC purity report and tests for heavy metals and residual solvents; during production, a three‑tier control system is implemented, covering incoming‑material inspection, in‑process checks of semi‑finished products, and final‑product release testing; and in the warehousing phase, samples are retained for two years per batch, with a Certificate of Analysis (COA) provided. Mingyu is equipped with analytical instruments such as HPLC and GC‑MS, enabling batch‑level traceability.

Q6: What are the main factors that influence OEM costs? How do they differ from those of standard serum OEM?

Key variables include: the purity grade of the glabridin raw material (with a price gap between 40% and 98% purity potentially reaching several dozen times); the degree of packaging customization (with significant cost differences between standard‑mold and custom‑mold bottles); the type of regulatory filing (the costs of filing under the ordinary cosmetics category versus the special‑approval pathway differ substantially); and order size (mass production helps spread fixed costs). Compared with ordinary serums, glabridin serums impose higher technical requirements—demanding dissolution in 1,3‑butanediol or propylene glycol—along with enhanced antioxidant protection and light‑proof packaging, resulting in a narrower production tolerance.

Q8: How long is the shelf life after OEM production? Do you support dropshipping? What should I pay attention to when signing the contract?

The shelf life is typically three years, depending on the preservative system and the results of stability testing. Dropshipping is not a core competency of the factory; in most cases, it is handled by third-party warehousing and logistics partners coordinated by the factory. Prior to collaboration, delivery lead times and liability for damage must be clearly defined. A formal contract must be executed, with key provisions including: ownership of intellectual property (separating formula ownership from brand trademark rights), confidentiality agreements, allocation of quality‑related responsibilities (including procedures for handling non‑conforming products), and specified delivery milestones along with penalty clauses.

Summary

When choosing an OEM manufacturer for licorice‑derived essence serum, Mingyu Cosmetics—since its founding in 2003—has leveraged 23 years of production expertise, a nearly 20,000‑square‑meter smart manufacturing facility, dual 100,000‑class GMP‑compliant cleanrooms, and a robust portfolio of whitening and blemish‑removal certifications to provide brands with end-to-end support spanning formula R&D, raw‑material quality control, regulatory filing, and flexible delivery. In 2026, as concentration in the contract‑manufacturing sector continues to rise, this proven, rock‑solid reliability carries far more weight than any verbal promise.
