Brief
In October 2026, a Brazilian nutritional supplement customer visited Tianjia’s manufacturing plant for a two-day on-site audit. Following the visit and review of key manufacturing and quality-control processes, the customer confirmed a long-term supply partnership with Tianjia.
The visit highlighted an important principle in B2B ingredient sourcing: building a reliable partnership requires more than competitive pricing. Manufacturing capabilities, product consistency, technical support, quality documentation, and transparent communication all play important roles in supplier selection.
For nutritional supplement brands and gummy manufacturers seeking a dependable ingredient partner, Tianjia believes that demonstrating these capabilities is essential to building long-term business relationships.
Highlights of This Factory Audit
For supplement brands, selecting a manufacturing or ingredient partner is a strategic decision. Before establishing a long-term relationship, buyers need to understand how a supplier manages production, quality, testing, and documentation.
During the two-day visit, the Brazilian customer reviewed several important aspects of Tianjia’s manufacturing and technical capabilities, including:
- Gummy production processes: Reviewing different gelling systems and their processing requirements.
- Production consistency: Examining depositing and in-line checkweighing processes relevant to piece-weight control.
- Stability evaluation: Reviewing accelerated stability testing and retained samples across formulations and packaging formats.
- Analytical capabilities: Learning about available testing for product characteristics, heavy metals, and other relevant quality parameters.
- Quality documentation: Reviewing applicable certificates, test reports, and production records.
These discussions helped the customer evaluate Tianjia’s capabilities based on its supply and product-development requirements.
What Tianjia Has to Support Long-Term Cooperation
1. Gummy Formulation and Processing
Nutritional gummies require careful coordination between the gelling system, sweetening ingredients, flavors, colors, and active ingredients. Different formulations may require different processing and drying conditions to achieve the intended texture and stability.
Tianjia’s documented manufacturing setup includes processing capabilities for gelatin and plant-gum systems, including pectin and carrageenan. Understanding the characteristics of each system helps manufacturers evaluate suitable approaches for different gummy product concepts.
2. Production Consistency and Dosage Control
For nutritional gummies, consistent piece weight is an important part of production quality. Tianjia’s documented production setup uses servo depositing and in-line checkweighing, with a reported single-piece weight tolerance of approximately ±5%.
Piece-weight control is one part of the broader quality process. Product-specific testing and appropriate analytical verification are also important when assessing active ingredient content and finished-product consistency.
3. Stability Testing and Quality Evaluation
Temperature, humidity, light, oxygen, and moisture migration can affect the quality of nutritional gummies during storage. Stability evaluation helps manufacturers understand potential changes and assess whether a formulation and packaging system are appropriate for the intended shelf life.
Tianjia’s source documentation describes accelerated stability testing under controlled temperature and humidity conditions, together with retained samples across different formulations and packaging formats. Accelerated testing supports product evaluation but should be interpreted alongside relevant real-time stability data when establishing shelf-life claims.
4. Analytical Testing and Documentation
Reliable supplier cooperation also depends on access to relevant quality information. Tianjia’s documented analytical capabilities include protein determination, spectrophotometric and chromatographic analysis, and facilities for heavy-metal testing.
Depending on the product and destination market, customers may need specifications, Certificates of Analysis (CoAs), allergen declarations, microbiological and heavy-metal reports, stability summaries, and applicable manufacturing certificates.
Factory Audit Matter to Global Food & Beverage Manufacturers
For international customers, a factory audit provides an opportunity to assess a supplier beyond its website, product catalog, or quotation. A well-structured audit can help buyers:
- · Understand the supplier’s manufacturing and technical capabilities.
- · Review relevant quality-control procedures and supporting records.
- · Evaluate production consistency and traceability arrangements.
- · Discuss product specifications and technical requirements directly with the supplier.
- · Identify documentation needs for the destination market.
- · Build confidence in communication and long-term supply planning.
The value of a factory visit lies in connecting a supplier’s stated capabilities with evidence that buyers can review and evaluate.
A Long-Term Partnership Built on Trust and Technical Communication
The Brazilian customer’s visit reflects Tianjia’s commitment to developing long-term B2B relationships through manufacturing capability, technical communication, and quality support.
For Tianjia, cooperation involves more than supplying ingredients. It also means understanding customer requirements, discussing formulation challenges, supporting appropriate testing, and coordinating the documentation needed for each project.
As nutritional supplement brands continue to develop gummy products with different active ingredients, sweetness profiles, textures, and market requirements, close collaboration between customers and suppliers remains important.
Tianjia looks forward to continuing its cooperation with the Brazilian customer and supporting its future product and supply needs.

Share your target active ingredients, desired texture, piece weight, product claims, annual volume, and destination market with our team to explore suitable ingredient and manufacturing options.
Tianjia uses production controls, piece-weight monitoring, and accelerated stability testing to help evaluate gummy quality and stability. Analytical testing capabilities and supporting documentation can also help customers assess whether products meet their specified quality requirements.
Depending on the product and applicable scope, customers can review relevant quality documentation and reports, including GMP-related documents, BRC, Kosher and HALAL certifications, and SGS or Intertek reports. Customers should confirm the validity, scope, and applicability of each document for their specific project.
Tianjia works with customers to evaluate gummy formulation and manufacturing requirements, including gelling systems, sweeteners, active ingredients, processing conditions, and quality expectations. International brands can contact Tianjia to discuss project requirements, documentation needs, and potential long-term supply cooperation.
They reviewed Tianjia’s gummy manufacturing processes, production controls, stability-testing procedures, analytical testing capabilities, and quality documentation. These assessments helped the them evaluate whether Tianjia’s manufacturing capabilities aligned with its product quality and supply requirements.
