Zinwi Bio controls product safety throughout the entire process

Amidst rising societal concerns about product safety, consumers are increasingly demanding higher standards of production and safety across all product categories. In response to this heightened scrutiny, we, as a leading e-liquid research and production enterprise, stand firmly with consumers by upholding our steadfast commitment to quality and safety.

Strict Raw Material Control to Ensure Pure Sources

We understand that premium products begin with high-quality raw materials. To this end, we have established a digital raw material repository. Only after passing a series of rigorous tests—including physicochemical analysis, restricted substance screening, and chemical composition testing—can raw materials enter our Zinwi supply chain. During the material acceptance phase, we conduct thorough sensory, physicochemical, and restricted substance tests to ensure the safety and purity of each batch of raw materials.

For key ingredients like PG and VG, we require suppliers to provide authoritative third-party test reports. Additionally, we conduct our own tests upon receipt, checking for purity, polycyclic aromatic hydrocarbons, E. coli, total bacterial count, molds, and yeasts to ensure no contamination during transport. Our stringent review standards ensure product safety from the very source.

Rigorous Production Processes to Guarantee Product Quality

Our production facilities include GMP-certified clean rooms with comprehensive dust removal measures such as physical isolation, pressure differentials, and total fresh air systems. Raw materials, packaging materials, and personnel entering the workshop must go through air showers and disinfection corridors to maintain cleanliness. Daily ultraviolet and ozone disinfection routines ensure a dust-free production environment.

We have dedicated storage rooms for packaging materials, where they are inspected for damage upon arrival and covered with double layers of plastic film. Any damaged materials are immediately returned and never used. Our implementation of MES and intelligent production systems ensures strict adherence to production protocols, maintaining the quality and safety of our e-liquids.

During production, each mixing tank produces only one flavor at a time, with all tools subject to unique identification codes. We use pure water operations in the workshop and employ a fully automated CIP cleaning system to ensure the purity of tanks and production tools, preventing cross-contamination, oil residue, and excess moisture. This meticulous process guarantees each drop of e-liquid delivers the purest flavor for the best sensory experience.

Comprehensive Quality Testing to Ensure the Safety of Every Drop

Our quality testing spans the entire production process, from raw materials to finished products. Our dedicated IPQC team conducts routine inspections every two hours, strictly enforcing management standards. 

E-liquids are directly filled and sealed in our GMP workshop. Prior to filling, packaging materials undergo another round of stringent inspection and disinfection. Finished products are shipped in barrels using enclosed trucks, prohibiting customers from using tanker trucks for pickup. This ensures products remain uncontaminated during transport, delivering fresh, high-quality e-liquids to our customers promptly.

Advanced Research and Detection to Enhance Safety Standards

We continually optimize our existing management systems and invest in research and development to meet evolving safety challenges. By introducing advanced detection equipment and technologies, we can identify potential safety risks earlier and more accurately. For instance, in e-liquid R&D, we focus not only on sensory attributes like color and aroma but also on chemical analysis and microbiological testing to ensure product stability and safety.

Collaborating with esteemed research institutions, we conduct in-depth studies on e-liquid components. These collaborations help us ensure the safety of our current products while continually refining formulations to reduce potential harmful ingredients and enhance product safety.

Professional Support for PMTA Certification

Zinwi is not only concerned about the safety and quality of the products themselves, but also committed to helping customers apply for the PMTA certification, from the analysis of product composition to the strict control of manufacturing standards, using strong measures to ensure that upstream procurement of raw materials, eliquid blending and processing, and downstream delivery of the finished product of the whole process of safety is strictly controlled, the whole process of escorting the customer to complete the smooth completion of the application for the PMTA.

Promoting Industry Standards and Protecting Consumer Health

We recognize that consumer health and safety can only be guaranteed through stringent industry standards and self-regulation. Therefore, we actively participate in setting industry standards, collaborating with regulatory agencies, industry associations, and other companies to foster the healthy and orderly development of the e-cigarette industry.

Choosing Zinwi means choosing safety, quality, and trust. In light of current concerns about product safety, we pledge to maintain our rigorous standards, continuously enhancing product quality and safety. We understand that e-liquids are ultimately inhaled into the human body and must therefore meet the highest safety standards to earn consumer trust in a competitive market. Let us work together to promote the standardized development of the e-cigarette industry, protect consumer health, and create a brighter future.
