Confirm the material
Name the grade, condition and specification; a trade name alone may be incomplete.
For your project: Reduce ambiguity before sourcing.
MATERIAL RECORDS FOR YOUR PROJECT
Know What Material
Went Into Your Part.
Define your material certificate and heat / lot traceability requirements before production. Connect the requested grade, supplier records and delivered batch so your team can review the evidence it actually needs.
Send Your Drawing & Documentation Requirements →Provide your required document types and format with the drawing. Availability, cost and timing are confirmed for your project.
TRACEABILITY OVERVIEW
Build Your Documentation Plan Around Your Requirements
Start with your drawing, material specification and customer requirements. Agree what each record must identify, how it links to the order and who reviews it before release.
- Confirm grade, condition and applicable specification
- Identify required heat, resin lot or supplier batch information
- Define the link from incoming material to the manufacturing batch
- Agree certificate and inspection record formats
- Record drawing revision and any approved substitutions
- Define retention and delivery requirements
5 Checks Before You Request Material Records
Keep heat / lot identity
Specify the identifier and the production stage where it must be retained.
For your project: Make your requested batch link reviewable.
Link records to parts
Agree whether your PO, part number, lot or serial number appears on the record.
For your project: Avoid receiving an unrelated certificate.
Control revisions
Use the approved drawing and document revision; record any accepted change.
For your project: Prevent repeat builds using outdated inputs.
Plan repeat orders
Confirm whether the next order uses a new material lot and needs new evidence.
For your project: Review the next batch instead of reusing an old report.
Choose the Material Records Your Project Needs
7 topics to discuss before sourcing. Each record’s scope must be agreed for your order.
Material Certificates for Your Metal Parts
- Specify alloy, grade, temper or condition and required standard
- Request the supplier or mill record scope before sourcing
- Confirm the required heat / lot identifier and link to your build
Your benefit: review the requested material evidence against a defined specification.
Batch Records for Your Engineering Plastics
- Identify exact resin grade, supplier and any additive or color requirement
- Agree resin lot, certificate of analysis or supplier declaration scope
- Review substitutions and application requirements before ordering
Your benefit: distinguish a named polymer family from the precise grade your part requires.
Choose the Evidence Your Specification Calls For
- An MTR commonly reports material properties and batch identity
- A COA records the supplier’s specified analysis or test scope
- Agree required fields; names and scope vary by supplier and material
Your benefit: request the actual data fields you need instead of assuming a document title guarantees them.
Define What Your CoC Must Identify
- State the part, order and revision represented by the declaration
- Agree the specification or requirements referenced
- Request supporting test records separately when your program needs them
Your benefit: separate a statement of conformity from measured material or dimensional results.
Review Your Requested Substance Documentation
- Provide the applicable customer requirement and intended scope
- Confirm supplier evidence availability for the material and finish
- Agree whether a declaration, test report or other record is required
Your benefit: identify documentation gaps before placing the order. No blanket compliance claim is implied.
Review Each New Material Batch
- Confirm changes in material supplier, grade, condition or finish
- Agree how a new heat / lot links to the repeat production batch
- Keep the approved revision and new records associated with your order
Your benefit: avoid treating the previous order’s material report as evidence for a different batch.
Match Records to Your Customer’s Format
- Provide the document template and applicable instructions
- Agree required fields, review owner and release conditions
- Confirm retention period and delivery method for the project
Your benefit: uncover unavailable records and extra work before a submission deadline.
5 Record Types: Different Evidence for Different Questions
Material certificate / MTR / COA
Supplier or mill evidence within its stated property and batch scope.
When to request: When the specified material properties or batch evidence must be documented.
Material traceability records
Links between material identifiers and agreed manufacturing or delivered batches.
When to request: When your program needs records connecting material to parts.
Certificate of conformance
A declaration against the agreed part and specification scope.
When to request: When your purchase requirements call for that declaration.
Customer documentation
Your required formats, submission artifacts and approval records.
When to request: When your customer specifies additional records; availability is reviewed.
Inspection records
Results for agreed characteristics, sample, revision and method.
When to request: When dimensions or other specified checks need recorded results.
Compare What Each Record Actually Shows
| Record | Main purpose | Heat / lot | Link to parts | Measurement evidence |
|---|---|---|---|---|
| Material certificate | Material properties within the report scope | Check report | Only if explicitly linked | Not a dimensional report |
| Traceability record | Chain or batch association | Agreed identifiers | Agreed batch / part link | Not material test results |
| CoC | Declaration against specified scope | If required | Part / order / revision as agreed | Not a substitute for requested test data |
| Inspection report | Measured characteristics in scope | If required | Identified sample / batch | Agreed results |
| Customer package | Customer-specific evidence set | As required | As required | As required |
6 Documentation Gaps to Resolve Before Your Build
Unclear material grade
Your review: Confirm exact grade, condition and specification before sourcing.
Missing heat / lot reference
Your review: Agree the required identifier and where it must remain visible.
Unrelated certificate
Your review: Define the certificate-to-order and material-to-part links.
Mixed batches
Your review: Agree segregation and identification requirements for your program.
Revision mismatch
Your review: Review the document against the approved part and drawing revision.
Records requested too late
Your review: Include documentation scope at quotation; later recovery may be limited.
Your 6-Step Material Documentation Review
Use this checklist to agree responsibilities and record scope for your project.
Confirm requirements
Define material, part revision, record types and approval owner.
Review supplier evidence
Confirm the available certificate and identifier scope before sourcing.
Record batch identity
Agree the incoming material and order association.
Maintain build links
Keep the specified batch identification through the agreed process stages.
Check the record set
Review part links, revisions and required inspection evidence.
Release agreed records
Deliver the agreed documentation with the identified order or batch.

Your Material Certificate & Traceability Questions
Does a material certificate prove the finished part meets every requirement?
No. It addresses its stated material evidence scope. Dimensions, finish, function and other requirements may need separate checks.
Is a CoC the same as an MTR?
No. A CoC is a declaration against a specified scope. An MTR generally reports material properties and batch information within its report scope. Agree which evidence your order requires.
Can you recover a missing certificate after manufacture?
Do not assume it can be recovered. Availability depends on the supplier and preserved identifiers. Request the required records before sourcing.
Can the same certificate be used for a repeat order?
Only review it as evidence where the material and batch association is valid. A new material lot may require new records.
Are RoHS or REACH documents included automatically?
No blanket inclusion is promised. Provide your applicable requirements so evidence availability and scope can be reviewed for the material and finish.
How long are records retained?
Specify the retention period and access requirements with your inquiry. Confirm responsibilities and availability for the project before the order.
