Changing a functional food contract manufacturer is a strategic decision that directly impacts product quality, brand reputation, and business performance. This is not merely a matter of switching suppliers, but rather a comprehensive transformation project that requires thorough preparation in legal, operational, and collaborative aspects.
If your business is planning to convert a functional food processing plant, join Life Gift Vietnam in reviewing the detailed guide below to ensure the process is conducted legally, safely, and efficiently.
Legal Preparation – A Mandatory Foundation When Changing Contract Manufacturers
Assessment of the Legal Capacity of the New Plant
Food Safety Certificate: The facility must meet the requirements for producing dietary supplements.
GMP Certificate: Must be valid and appropriate for the dosage form (capsules, syrup, tablets, gel, oral powder, etc.).
Prepare the application documents for re-registration of the product declaration
From the new factory:
Notarized copies of the Food Safety Certificate and GMP Certificate.
From the company:
The Product Declaration (Form No. 02) has been updated to include the new factory name and address.
Test report from the pilot production batch (valid for ≤ 12 months).
New product label template with accurate information from the manufacturer.
📍 Note: Effective July 1, 2025, applications for the renewal of product notifications must be submitted to the Department of Health in accordance with Decree 148/2025/NĐ-CP.
Businesses need to thoroughly prepare their legal documents to ensure a smooth transition.
Preparing for Collaboration and Operations—A Critical Step in Ensuring Success When Changing Contract Manufacturers
Alongside the legal aspects, commercial and operational preparations will determine the success of the transition.
Termination of the Contract with the Former Factory
Resolve accounts receivable, inventory, packaging, and related assets.
Ensure a transparent and professional liquidation process.
Sign a comprehensive contract with the new factory
Confidentiality Provisions Regarding Formulas and Manufacturing Processes.
Quality Assurance (QA) Agreement from Raw Materials to Finished Products.
Clearly define responsibilities, obligations, and production schedules.
Technology Transfer & Pilot Production
Plan the transfer of formulas and production processes.
Produce a pilot batch to both assess production capacity and obtain samples for testing to support the documentation.
This step helps businesses control quality and optimize costs when partnering with a new manufacturing facility.
Develop a detailed roadmap for transforming the functional food processing plant
To avoid risks and production disruptions, businesses should develop a phased transition plan:
→ Identify partners; assess their legal standing and actual production capabilities.
→ Signing the contract, requesting legal documents, producing a pilot batch, and conducting testing.
→ Resubmit the product registration application to the Department of Health and monitor the progress.
Launch → Plan commercial production, print new packaging, manage inventory, and launch the new product into the market.
A clear roadmap helps businesses effectively manage risks and ensure supply chain continuity.
👉 In summary, changing contract manufacturers is a project that requires thorough preparation. By taking a systematic approach and preparing in detail—both legally and operationally—your business can ensure a smooth transition, minimize the risk of disruption, and maintain sustainable growth in the market.
