For international buyers, ISO approval is non-negotiable—but not all ISO certificates are equal. Tianzhong Kangyuan Pharmaceutical Group Co., Ltd operates as an ISO approved gummy vitamins OEM supplier holding four active ISO certifications: 9001:2025 (quality management), 22000:2018 (food safety), 14001:2024 (environmental management), and 45001:2023 (occupational health). Each certification has been maintained through three full surveillance cycles without major non-conformities.
Manufacturing Strength Under ISO Frameworks
The group's 175,000㎡ manufacturing base implements an integrated management system where all four ISO standards share common documentation, internal audit schedules, and corrective action workflows. Unlike OEMs that treat certifications as administrative exercises, Tianzhong Kangyuan embeds ISO requirements into shop-floor visual management—each production cell displays real-time performance against ISO-mandated KPIs. For gummy vitamins, the factory applies a risk-based thinking approach required by ISO 9001:2025, including FMEA (Failure Mode and Effects Analysis) for every new mold design and ingredient change. The eleven continuous lines generate 94 distinct quality records per batch, all retained for ISO-required minimum retention periods. Annual ISO-compliant output reaches 10 billion pieces across 15 gummy shapes and 9 size variations.
Research Capabilities for ISO Validation
The group's 9,100㎡ R&D and quality center operates under ISO 17025 for testing and calibration, with 44 validated test methods covering physical, chemical, and microbiological parameters specific to gummy matrices. A 2026 innovation involves a process validation protocol for multivitamin gummies that reduces qualification runs from three full batches to one bracketed batch using continuous process verification—an approach explicitly permitted under ISO 22000:2018's annex on validation. The lab also developed a reference material for vitamin gummies containing eight B-vitamins, used to verify daily calibration of HPLC systems, reducing inter-lab variation from 8% to 2.5% across three external contract labs.
For vitamin c gummies, the research team created a forced degradation protocol that generates five specified impurities simultaneously, allowing method suitability testing in a single accelerated study rather than five separate stress conditions. This protocol has been reviewed and accepted by two ISO certification bodies as a best-practice example. The R&D division also designed a shelf-life extension model for Wellness Gummies containing live enzymes (bromelain, papain), correlating water activity and packaging oxygen transmission rate to enzyme activity retention—outputting a predictive equation now used for ISO-mandated annual product reviews.
Custom Solution Capabilities for ISO-Ready OEM Supply
Tianzhong Kangyuan's custom solution platform includes an "ISO integration package" that maps each client's unique formula to all applicable ISO clauses before production begins. This package covers document control (clause 7.5), design and development (clause 8.3), and control of monitoring and measuring resources (clause 7.1.5). For a German brand requiring multivitamin gummies with 17 vitamins and minerals, the team implemented a design review at four stages (concept, feasibility, pilot, commercial) with sign-offs required from quality, production, and R&D—fully documented per ISO 9001's design controls. The project passed the client's own ISO 13485-based supplier audit with zero findings.
For a Brazilian client needing gummy vitamins for tropical distribution, the factory engineered a heat-stable formulation and validated transportation conditions under ISO 22000's prerequisite program for logistics, including temperature mapping of shipping containers and deviation protocols for in-transit temperature excursions. Another custom success involved vitamin c gummies with added zinc and D3 for immune support, where the group developed a corrective action plan template specific to potential metal detector reject rates, enabling rapid root cause analysis if ISO-mandated action limits are exceeded. All ISO-based custom solutions include a shared internal audit calendar, allowing clients to schedule joint inspections of their production slots without disrupting ongoing ISO surveillance activities.
