The transfer of analytical procedures (TAP), also referred to as method transfer, is the documented process that qualifies the receiving unit to use an analytical test procedure that originated in the transferring unit, thus ensuring that the receiving unit has the procedural knowledge and ability to perform the transferred analytical procedure as intended.
Purpose
The purpose of this procedure is to provide guidelines for the studies required and propose minimum requirements and acceptance criteria for the transfer of analytical methods.
Guidelines are also provided for the design, approval, and execution of analytical method transfer protocols.
Scope
This procedure applies to analytical methods transferred from any originating laboratory to any receiving laboratory, either internal or external to PharmaInfo Pvt Ltd.
This procedure outlines the minimum studies required for the transfer of analytical methods. Additional or different transfer approaches may be considered and documented in the method transfer protocol with scientific justification.
This procedure applies to chemical analytical methods for testing API, excipients, applicable commodities, packaging components, cleaning samples, in-process samples, and finished pharmaceutical products.
This procedure does not apply to microbiological methods or device test methods.

Procedure:
This SOP Presents the components necessary to complete a successful method transfer by using various types of method transfer.
General considerations
The purposes of performing method transfer studies are:
- To demonstrate that the suitability of all testing methods used shall be verified under actual conditions of use.
- To verify that the method will perform in the Receiving Laboratory as it did during the validation studies.
- The transfer of methods, when necessary, may involve sending the appropriate subject matter expert (SME) to train the lab analysts in the receiving lab priorto a formal transfer 1study. The completion of the training will be documented in a notebook by the Receiving Laboratory.
- The Method Transfer Protocol consists of studies that will demonstrate that the Receiving Laboratory can successfully perform the method as written in the test procedure without any additional information. If additional information is required to successfully execute the method, this information must be documented in the analyst’s notebook and included in the final test method.
- The intended use of the method as well as the method’s difficulty to execute (complexity) will dictate the needed steps in the transfer process. Chromatographic methods (TLC, HPLC, GC) are classified as moderately complex to complex and require
- formal method transfer. The acceptance criteria presented in this procedure may be modified or adjusted based on actual needs and method / equipment capabilities. Justification for all modifications from the approach presented in this procedure must be included in the individual method transfer protocol.
- Methods transferred from one laboratory to another require an approved Method Transfer protocol and a Method Transfer report. The Method Transfer protocol and report must be approved by the appropriate signatories as specified in the Approvals Section before beginning any transfer activities.
- The test method shall include but not be limited to the following solution preparation elements:
- System Suitability
- Solution Preparation
- Reference Standards
- Stability of Solutions (if available)
- Description of Equipment
- Special Handling Instructions (i.e. protect from light, refrigeration needed, special glassware…etc.)
- Calculations
- How to Report Data
All equipment involved in the method transfer must be qualified and calibrated in the operating range established in the method before use.
Analytical Tests:
- Analytical methods like but not limited to Assay, Related Substances, Dissolution / Drug Release, Residual Solvents, etc., for which Analytical Method Validations have been carried out at the Transferring unit, shall be included in the Method Transfer program.
- Head, of QA/QC, and the Head, of R&D- Analytical shall have the rationale for any methods not included (transfer waiver). Additional pharmacopoeial tests like identification, moisture content/LOD, pH and optical rotation/specific optical rotation, and any other test as applicable in individual monograph/specification shall be considered during the method transfer.
- Method transfer for analytical methods for raw materials shall be carried out based on the criticality of the method, as agreed by the Head, QA/QC Head R&D – Analytical.

The Chemist/analyst, receiving unit (QC/another laboratory) shall perform the analysis in triplicate and provide the results to the transferring unit.
B. Direct Transfer:
- This type of method of transfer shall include the physical demonstration and joint analysis of the sample by the Transferring unit and the Receiving unit.
- The transferring unit visits the receiving unit and demonstrates the method by analyzing the sample as per the protocol. After a demonstration by the transferring unit, the Receiving unit shall perform the analysis independently.

Complete or Partial Method Validation or Revalidation
- Revalidation or partial revalidation is another acceptable type of method transfer wherein those characteristics that are anticipated to be affected by transfer are addressed.
- Following are the characteristics addressed in Revalidation or partial validation:
- Submission to the regulatory agencies of a revised analytical procedure.
- Use of an established general procedure with a new product or raw material.
- Changes in the composition of the drug product.
- Changes in analytical procedures.
- Omission of Formal Transfer, Transfer Wavier
- In this type of method transfer under certain circumstances, the receiving unit is considered to be qualified to use the analytical test procedures without comparison and generation of inter-laboratory comparative data.
- The following are circumstances that may justify a transfer wavier:
- The new product composition is comparable to that of an existing product and/or the concentration of active ingredient is similar to that of an existing product and is analyzed by procedures with which the receiving unit already has experience.
- The analytical procedure being transferred is described in the Pharmacopoeia and is unchanged. Verification should be applied in this case.
- The analytical procedure transferred is the same as or very similar to a procedure already in use.

Note: If eligible for transfer waiver, the receiving unit should document it with appropriate justification.
