BIS Factory Inspection Checklist for Manufacturers
The Indian Standard had been identified, the forms had been submitted, the factory team knew that BIS would visit, and management assumed the difficult part was already over.
Then the inspection preparation started.
One test instrument had an expired calibration certificate. The production flow shown in the application no longer matched the actual shop floor. The quality-control executive could not clearly explain how batches were released. Raw-material certificates were stored across different departments. And the product that would be offered for testing was not from a clearly traceable production batch.
None of these problems required rebuilding the factory. But together, they showed something important: being capable of manufacturing a product is not the same as being ready for a BIS factory inspection.
For Scheme I applications, BIS assesses the manufacturing infrastructure, production process, quality control and testing capabilities or declared arrangements of the manufacturer through a factory visit. Product conformity may also be established through factory testing, third-party laboratory testing or a combination of the two.
That means your preparation should begin well before an inspection date is confirmed.
What Is a BIS Factory Inspection?
A BIS factory inspection is an assessment of whether the manufacturing unit seeking certification has the infrastructure, controls and testing capability or arrangements needed to manufacture conforming products consistently.
The inspection is not limited to checking whether machines exist.
The inspecting team may need to understand whether the factory you described in your application is the factory actually operating on the ground.
That can involve verification of:
- Manufacturing infrastructure
- Production process
- Quality-control arrangements
- Testing capabilities
- QC personnel
- Calibration records
- Raw-material controls
- Factory layout
- Product samples
- Testing arrangements
- Marking information
- Records and supporting documentation.
The exact requirements depend on the product, Indian Standard and applicable BIS Product Manual or other product-specific guidance.
Is Factory Inspection Required for Every BIS Certification?
No.
This distinction should be made before using any generic factory inspection checklist.
Scheme I – ISI Mark
Factory assessment is an important component of the Scheme I grant-of-licence process. Current BIS guidance provides for a visit to evaluate manufacturing infrastructure, production, quality control and testing arrangements.
FMCS
Foreign manufacturers seeking certification through the applicable Scheme I/FMCS pathway should prepare for assessment of their overseas manufacturing unit. Current Scheme I guidelines state that foreign-manufacturer Grant of Licence cases are processed under Option 1.
CRS – Scheme II
Do not automatically use this checklist for CRS.
Under CRS, BIS describes the registration mechanism around manufacturer self-declaration of conformity, necessary manufacturing/testing infrastructure and test reports from recognized laboratories. The application and scrutiny route is different from the Scheme I process discussed here.
Scheme X
Scheme X must also be assessed separately.
Under BIS machinery-safety guidelines issued on 5 August 2026, technical-file evaluation involves desk audit followed by site audit. The site audit can assess the technical file, manufacturing process, quality assurance measures and infrastructure.
So before preparing for “a BIS audit”, first identify the certification scheme.
30-Point BIS Factory Inspection Readiness Checklist
The following checklist can be used as an internal pre-audit tool. It is not a replacement for your product-specific Indian Standard, Product Manual or Scheme of Inspection and Testing.
1. Factory and Manufacturing Infrastructure
Before the visit, confirm that the physical factory matches the information submitted to BIS.
- Factory name matches application records
- Factory address is consistent across documents
- Manufacturing activities are actually carried out at the declared premises
- Manufacturing machinery required for the product is installed and operational
- Production flow can be demonstrated
- Raw-material storage areas are identifiable
- Finished-goods storage areas are identifiable
- Testing or laboratory areas are identifiable
- Subcontracted manufacturing activities have been correctly declared
- Current plant layout is available
The BIS self-evaluation format specifically asks for a plant layout and information about other owned or subcontracted premises where part of the manufacturing activity takes place.
A frequent preparation mistake is updating an application but forgetting that the plant layout, machinery list or outsourced process has changed since the documents were prepared.
The inspection team should not be discovering these differences for the first time during the visit.
2. Testing Facilities
Testing readiness deserves its own review.
Depending on the applicable Indian Standard and Product Manual, the manufacturer may need specified testing facilities or approved alternative testing arrangements.
Before inspection:
- Identify every test required under the applicable SIT or product-specific requirement
- Map each test to available equipment
- Identify tests performed internally
- Identify tests performed through permitted external arrangements
- Verify that equipment is functional
- Confirm required fixtures and accessories are available
- Keep operating instructions accessible
- Run trial tests before the inspection
- Ensure sufficient product or material is available for testing
- Ensure laboratory staff can demonstrate the procedure
BIS guidelines allow factory testing to be witnessed during the visit and provide specific arrangements for situations involving partial test reports or certain factory-testing cases.
Do not wait for the BIS officer to discover that a machine powers on but cannot complete the required test.
3. Calibration Certificates
A testing machine without valid measurement control can create an avoidable problem.
Current Scheme I guidance specifically lists calibration certificates of testing equipment among the items that may be verified during the factory visit, as applicable.
Check:
- Equipment identification number
- Calibration status
- Calibration date
- Calibration due date
- Measurement range
- Instrument location
- Certificate traceability
- Whether the equipment in the certificate is the same equipment physically available
Do not simply create a folder called “Calibration”.
Match each required test with the instrument used to perform it and then match that instrument with its calibration evidence.
4. Quality-Control Personnel
The factory should have people who understand the quality-control system, not merely names entered into a form.
The BIS self-evaluation format asks manufacturers to identify quality-control staff including their designation, qualifications and experience.
Before inspection, make sure relevant personnel can explain:
- What is tested
- When it is tested
- Who performs the test
- How results are recorded
- What happens if the result fails
- How a batch is accepted or rejected
- How equipment calibration is controlled
- How non-conforming product is segregated
A practical approach is to conduct an internal mock interview with the quality-control team.
5. Raw Materials and Components
Depending on the product standard, raw-material conformity may also need to be demonstrated.
BIS’s current Scheme I guidance distinguishes situations where a referenced raw-material standard is only guidance from situations where conformity of the raw material is a mandatory requirement of the product standard.
Review:
- Major raw materials identified
- Approved suppliers documented
- Supplier certificates available where relevant
- Incoming inspection records available
- Batch or lot identification is maintained
- Material can be traced into production
- Mandatory raw-material conformity evidence is available where applicable
The BIS self-evaluation report also asks for information including the raw material, supplier, certification status, supplier test certificate and how received lots or batches are handled.
6. Production and Process Control
Your production process should tell the same story as your technical documents.
Prepare a simple process flow covering:
Raw material → Incoming inspection → Manufacturing → In-process control → Final inspection/testing → Packing → Finished goods
Then walk through the actual factory using that flow.
Look for discrepancies.
For example, your submitted documents may say a particular process is performed in-house, while production has since moved to a subcontractor.
Current BIS guidelines identify a major deviation from declared manufacturing arrangements during the factory visit as a potential issue in processing an application.
7. Factory Documents
Create one controlled inspection file rather than asking five departments to search for documents while the inspection is happening.
The file may include, as applicable:
- Application documents
- Self-evaluation cum verification report
- Plant layout
- Factory location plan
- Quality-control personnel details
- Equipment list
- Calibration certificates
- Raw-material test certificates
- Product test records
- Supplier documents
- Outsourced-testing declarations
- Quality Assurance Plan
- Scheme of Inspection and Testing
- Product Manual
- Product drawings
- Process flow
- Previous licence information
- Corrective-action records
- Marking artwork
- Batch identification procedure
Current BIS factory-visit guidance expressly identifies several of these documents for verification.
8. Marking and Traceability
Do not leave marking preparation until after technical testing.
The BIS self-evaluation format asks for details concerning packing, article marking, method of marking, labels and batch or code numbering.
Before inspection, verify:
- Proposed product marking
- Brand name
- Product identification
- Batch or lot number
- Relevant standard information
- Packaging
- Traceability mechanism
Actual Standard Mark usage and licence-number marking must follow the applicable regulatory and product-specific requirements after authorization. Current BIS Scheme I guidance requires compliance with the applicable labelling and marking provisions of the Conformity Assessment Regulations and relevant Indian Standard.
9. Sample Readiness
Inspection preparation should also include sample planning.
Under the current Scheme I guidelines, samples may be drawn during factory visits depending on the applicable Grant of Licence route and product requirements. Sampling is linked to product-specific guidelines and the varieties proposed within the licence scope.
Before the visit:
- Identify the models or varieties included in the application
- Understand applicable grouping guidelines
- Keep representative production available
- Maintain batch traceability
- Keep sufficient material available
- Ensure samples match the declared product scope
Do not manufacture an unidentified “audit sample” that cannot be connected to routine production records.
What Can Go Wrong During BIS Factory Inspection?
Many problems are operational rather than dramatic.
Common readiness gaps include:
- Calibration has expired.
- Required testing equipment is unavailable.
- Testing personnel cannot demonstrate the test method.
- Manufacturing machinery differs from submitted information.
- Raw-material records cannot be traced.
- Product scope and physical samples do not match.
- Outsourced processes have not been properly documented.
- Inspection records are incomplete.
- Quality-control responsibilities are unclear.
- Factory marking differs from submitted artwork.
- Sample production is not ready.
- Documents use inconsistent company or factory names.
One particularly important point is factory testing.
Under current Scheme I guidance, if a non-conformity is observed during applicable factory testing, the applicant may be required to make improvements that are verified through another inspection and factory testing before the process can move forward.
That is why a mock audit should happen before the BIS visit, not after a discrepancy appears.
Illustrative Business Case
Consider an electrical-product manufacturer preparing for its first Scheme I inspection.
The company had purchased all required testing equipment. Management therefore considered the laboratory ready.
During the internal readiness review, however, the compliance team found three gaps:
- One instrument’s calibration had expired.
- Two tests had no approved recording format.
- The QC engineer who normally operated the equipment was unavailable during the proposed inspection week.
The company delayed declaring readiness, corrected the calibration status, completed trial testing and assigned an alternate trained employee.
The lesson is straightforward:
Factory readiness is not determined by whether equipment exists. It is determined by whether the complete quality-control system can operate and demonstrate conformity when required.
This is an illustrative business case, not a representation of an actual Beyond BIS client result.
Inspection Day Responsibility Matrix
| Area | Recommended Responsible Person |
|---|---|
| Application and BIS documents | Compliance coordinator |
| Factory tour | Plant head |
| Manufacturing process | Production manager |
| Quality system | Quality manager |
| Laboratory testing | QC engineer / laboratory personnel |
| Calibration | Quality or metrology team |
| Raw-material records | Purchase + quality team |
| Product samples | Production + quality |
| Marking and packaging | Quality + packaging team |
| BIS communication | Authorized company representative |
The objective is not to create ten presenters.
It is to make sure the right person is available when a technical question arises.

- Relevant product is available
- Test equipment is working
- Calibration status has been checked
- QC personnel are available
- Required testing can be demonstrated
- Factory layout is current
- Manufacturing process matches submitted information
- Raw-material records are available
- Testing records are organized
- Relevant Product Manual and SIT have been reviewed
- Samples can be traced to production
- Marking details are ready for review
- Subcontracting arrangements are documented
- Previous discrepancies have been closed
- One coordinator has been assigned for the entire inspection
How Long Does a BIS Factory Inspection Take?
For Scheme I, BIS’s Grant of Licence guidelines dated 25 February 2026 state that a factory visit is normally one day for Indian manufacturers and two days for foreign manufacturers. BIS may determine that additional time is needed depending on the circumstances, including cases involving extensive factory testing.
This should not be interpreted as a guaranteed audit duration.
The product, manufacturing process, scope, testing requirements and observations during assessment can affect the actual visit.
The Most Important Rule: Prepare for Your Product, Not for a Generic Audit
A generic factory checklist is useful for readiness.
It is not the final compliance requirement.
BIS explicitly states that product-specific guidelines must also be followed where applicable.
Before declaring your factory ready, bring these documents together:
Indian Standard + Product Manual + Scheme of Inspection and Testing + applicable BIS guidelines + your actual manufacturing process
Then test your factory against them.
That is a much stronger approach than preparing from a generic list downloaded the night before the inspection.
Conclusion
A BIS factory inspection is not simply a visit to see whether a factory exists.
For Scheme I, BIS assesses the manufacturer’s infrastructure, production process, quality-control system and testing capability or arrangements. The documentation should support what is happening physically on the shop floor, and the shop floor should support what was declared in the application.
The best preparation therefore starts with three questions:
Can we manufacture the product consistently?
Can we demonstrate the required tests and controls?
Can our records prove what we are doing?
If any of those answers is unclear, the factory is probably not inspection-ready yet.
