Shenzhen Renda Shun Supply Chain Co., Ltd.

Pre-Production Phase: Precision Preparation
This phase translates the approved formula into manufacturable specifications.
Bill of Materials (BOM) Finalization: Precise quantities for all raw materials are locked in for production scaling.
Packaging Design & Sourcing: For ODM projects, we offer full packaging design services. For OEM, we source and qualify client-provided packaging materials (laminate tubes, caps, cartons).
Production Line Scheduling & Setup: The designated manufacturing line is configured and sanitized according to the product's specific formula and batch size.

Our Factory operates a versatile, state-of-the-art production facility with dedicated lines for modern oral care formats. Our integrated setup ensures cross-contamination control, formulation integrity, and manufacturing excellence across all product types.

Flexible Manufacturing: We operate state-of-the-art, dedicated production lines to expertly manufacture a diverse range of formats.All lines share integrated quality control checks and packaging operations to ensure final product integrity.

Uncompromising Quality: Integrated quality control checks are embedded at every stage—from raw material sourcing to finished goods—ensuring every product meets the highest standards of consistency, safety, and performance.

Why Partner with Woadee?
We offer more than just production; we provide a seamless, single-source solution. Our combination of creative R&D, versatile manufacturing, and stringent quality assurance makes us the ideal partner for brands looking to develop or expand their oral care portfolio with confidence and efficiency.

Full-Chain Quality Assurance System

Adhering to the principle that "Quality is built in through design and refined in manufacturing," Implements a four-stage quality inspection process that spans the entire product lifecycle. This ensures that every product meets the highest standards.

1. Incoming Quality Control (IQC)
Sample Inspection: Samples are taken from all arriving raw materials (abrasives, fluoride, flavors, etc.) and packaging materials (tubes, cartons).

Key Indicator Testing:

Raw Materials: Purity, particle size distribution, microbial limits, and moisture content are tested.

Packaging Materials: Dimensions, seal integrity, printing accuracy, and material compliance are checked.

Release Handling: Only batches that pass inspection are stored in the warehouse and approved for production use.

2. In-Process Quality Control (IPQC)
Real-time monitoring on the production line ensures critical process parameters remain controlled.

Material Feeding Verification:Confirmation that the type, sequence, and weight of materials fed into the process strictly match the formula.

Semi-Finished Product Testing:After mixing, samples are tested for viscosity, pH, relative density, color, and taste to ensure uniform texture.

Environmental Monitoring:Continuous monitoring of the production workshop's temperature, humidity, air pressure differentials, and microbial levels.

3. Final Quality Control (FQC)
Final release inspection is conducted on fully packaged products.

Visual Inspection: Packaging is checked for damage, print clarity, and cleanliness.

Net Content Check: Ensures product net content complies with regulatory requirements.

4. Retention Sample Stability Testing
Batch-by-Batch Retention: A specified quantity of samples is retained from every production batch.

Continuous Monitoring: Retained samples are placed under controlled temperature and humidity conditions for long-term stability studies. Their physicochemical and microbiological indicators are monitored throughout the product's shelf life to guarantee stability.

Through this interlocking quality inspection process, We have built a comprehensive quality firewall, delivering safe, stable, and effective oral care products to every customer.

Our R&D engine is the foundational step for all projects, ensuring scientific rigor and market relevance.
Market Analysis & Concept Development: We collaborate with clients to analyze trends, identify target demographics, and define a unique product concept (flavor, function, claims).
Formula Design & Engineering: Our chemists develop custom formulations or adapt existing ones to meet specific requirements (e.g., anti-cavity, whitening, sensitivity, natural/organic).
Raw Material Sourcing & Qualification: We rigorously vet and pre-qualify all ingredients (abrasives, humectants, binders, fluorides, active ingredients) for quality, safety, and efficacy.
Stability & Compatibility Testing: Prototypes undergo extensive testing for shelf-life, pH stability, viscosity, fluoride activity, and tube compatibility to ensure product integrity.
Sensory Evaluation: Panels assess flavor profile, mouthfeel, aftertaste, and texture to guarantee a superior consumer experience.
Clinical Testing & Certification: We facilitate and manage third-party clinical trials to validate efficacy claims (e.g., whitening, plaque reduction) and ensure compliance with global standards (FDA, ISO, CE).

Core Business:Focusing on Amazon North America as the main platform, we deeply cultivate the North American e-commerce market, covering categories such as home furnishings, auto parts, kitchenware, and outdoor products.
