YOUR PART. YOUR EVIDENCE. YOUR APPROVAL REQUIREMENTS.
Quality Documentation for Your Custom Manufactured Parts
Define your manufacturing quality documentation package before production. Match FAI, PPAP, Control Plan, ISIR, COA and CoC requirements to your part, drawing revision, actual process and receiving needs.
Availability, formats, test scope, submission elements and charges require quotation review. No document type is automatically included merely because it appears here.
01 Define
Part, revision, specification and required evidence.
02 Agree
Documents, templates, sampling and approval timing.
03 Deliver
Records linked to your actual order and supplied identity.
4 Decisions Before Your Documentation Quote
For custom parts with inspection documentation, confirm what your receiving or approval team must actually verify.
Your Record List
Name each required document; avoid relying on “full quality pack” without a definition.
Your Coverage
Separate characteristics inspected, sample quantity and the delivered lot.
Your Format
Send customer templates, language, units and required reference standards.
Your Approval
Define reviewer, submission timing and who authorizes any exceptions.
6 Document Types. Different Questions Answered.
Quality documentation for custom manufacturing should state which evidence each document provides and which decisions remain with your team.
First Article Inspection: Connect Results to Your Drawing
A machined parts documentation package may need an agreed first-article report. Define the drawing characteristics, controlled revision, inspected samples, results and exceptions. A first-off check is not automatically a complete FAI.
| Your input | Controlled drawing, characteristic list, format and sample requirement. |
|---|---|
| Your record | Results identified to the relevant part, revision and sample. |
| Your review | Confirm deviations and required supporting evidence. |
| Scope boundary | An AS9102-style format does not establish AS9100 certification or aerospace approval. |
PPAP: Agree the Submission Before Production
Your production quality documentation package may require PPAP support. Specify the customer requirements, submission level, required elements and acceptance timing; a label on a folder is not an approved PPAP.
| Your input | Customer templates, submission level and required elements. |
|---|---|
| Your record | Agreed dimensional, material, process and other supporting evidence. |
| Your review | Identify required customer authorization and open items. |
| Scope boundary | Neither all PPAP elements nor customer approval are promised for every order. |
Control Plan: Define How Your Process Is Checked
A control plan connects the process, characteristics, methods, sample or frequency requirements and reaction instructions. It is a planning document; it does not replace actual inspection results.
| Your input | Applicable process route, characteristics and customer requirements. |
|---|---|
| Your record | Agreed method, frequency, responsibility and reaction plan. |
| Your review | Align the plan with actual operations and controlled revisions. |
| Scope boundary | Special tests, capability studies and monitoring requirements need separate feasibility review. |
ISIR: Define Your Initial-Sample Evidence
An initial sample inspection report supports the customer’s agreed initial-sample review. The required content depends on the customer and applicable format; ISIR, FAI and PPAP are not automatically interchangeable.
| Your input | Customer ISIR form, drawing revision and sample identification. |
|---|---|
| Your record | Agreed characteristic results and supporting sample evidence. |
| Your review | Record exceptions and the required approval response. |
| Scope boundary | An initial sample report does not by itself authorize all future production. |
COA: Identify the Analysis and Its Source
A certificate of analysis should identify its issuer, relevant material or batch, specification and stated analysis results. A material test report or mill test certificate may serve a different defined source or scope.
| Your input | Exact material grade, condition, required test or analysis and source requirements. |
|---|---|
| Your record | Available analysis evidence connected to the supplied material identity. |
| Your review | Check source, results, references and traceability relationship. |
| Scope boundary | A supplier COA does not imply independent retesting or every possible material property. |
CoC: State Conformance to the Agreed Order
A manufacturing certificate of conformance is a declaration linked to the supplied items and stated requirements. It is different from a list of measured inspection results or an original material analysis.
| Your input | Order, part, revision, required declaration and delivery identity. |
|---|---|
| Your record | Agreed conformance statement and applicable references. |
| Your review | Resolve authorized exceptions and required signatory details. |
| Scope boundary | A CoC does not replace test results, source evidence or customer acceptance. |
Separate the Declaration, Results and Source Evidence
Use this comparison when reviewing supplier quality documentation requirements.
| CoC declaration | States conformance to the agreed requirements; identify order, item and applicable references. |
|---|---|
| Dimensional inspection report | Records agreed measured characteristics, requirements, sample identity and findings. |
| FAI / ISIR | Presents the defined initial-sample evidence in the agreed format. |
| PPAP package | Combines the agreed submission elements for the specified customer approval process. |
| COA / MTR / mill certificate | Reports the stated analysis or tests from the identified issuer and material source. |
| Control Plan | Defines the agreed process controls and reaction instructions; actual execution records remain separate. |
For certificate of compliance in manufacturing, specify the exact requirement and declaration wording. A generic certificate is not proof of compliance with every regulation, product standard or market rule.
8 Gaps to Resolve Before Your Report Is Due
01
Specify Before the Work Begins
Late requests may require extra inspection, source retrieval or new tests, and some evidence cannot be recreated reliably.
| Request | List the document and required coverage on the RFQ. |
|---|---|
| Decision | Confirm feasibility and any added cost before order release. |
02
Keep Your Requirements and Results on One Revision
Manufacturing quality documents must identify the applicable part and controlled revision, including approved changes.
| Request | Supply current drawing, specification and revision references. |
|---|---|
| Decision | Confirm how affected records and samples will be updated. |
03
Do Not Confuse All Features with All Parts
A ballooned drawing inspection report can link characteristics to results. Characteristic coverage and sample quantity are separate decisions.
| Request | Define features, quantities, lots and relevant sampling requirements. |
|---|---|
| Decision | Confirm the exact inspection and reporting scope. |
04
Review Templates Before Committing
Customer specific quality requirements can add fields, evidence, signatures or acceptance steps beyond a standard report.
| Request | Provide the actual forms and instructions during quote review. |
|---|---|
| Decision | Resolve unavailable fields and special requirements in writing. |
05
Check the Actual Issuer and Identity
A material test report must relate to the supplied material. A copied report with the right grade name alone does not prove that link.
| Request | Specify source certificates and required material identity. |
|---|---|
| Decision | Review record availability before purchasing material. |
06
Request Process Evidence with the Operation
A heat treatment certificate or coating inspection certificate needs the relevant process, identity, requirement and evidence scope.
| Request | Name the required outside-process records and tests. |
|---|---|
| Decision | Confirm supplier availability and acceptance before processing. |
07
Keep Deviations Visible to the Reviewer
An inspection document package should not hide failed results, unverified characteristics or missing required records.
| Request | Define how exceptions are reported and escalated. |
|---|---|
| Decision | Identify the authorized disposition or customer approval. |
08
Agree What Is Supplied and Retained
A manufacturing data book can mean different things. Define its contents, delivery format, confidentiality and retention requirements.
| Request | List deliverables, permitted recipients and retention needs. |
|---|---|
| Decision | Confirm actual availability; no universal permanent-retention promise. |

Your Documentation Questions, Answered
What documents should accompany machined parts?
Specify the required dimensional report, material source evidence, CoC and any FAI, ISIR, PPAP or process records during RFQ. The correct list depends on the part, drawing, route, risk and customer requirements. The reviewed quotation confirms what is included.
Certificate of conformance vs material test report: what is the difference?
A CoC declares conformance to the stated order requirements. A material test report presents the stated material analysis or test results from its identified issuer. They answer different questions and both require the relevant item or source linkage.
Can quality documents be requested after production?
Ask the team to review what actual records exist and remain linked to your items. Extra inspection or tests may be needed, and missing original evidence may be unavailable. A new document must not fabricate results or reconstruct an unsupported material identity.
What is included in a manufacturing quality package?
Its agreed index can include inspection results, source certificates, conformance declarations, initial-sample evidence, process records or customer-specific submission elements. No universal package applies to every order. Define the actual contents and formats before production.
Are inspection reports included in manufacturing quotes?
Check the written quotation. Required characteristics, quantities, report format, tests and submission work may affect price and timing. Do not assume every report, source certificate or approval package is included in a basic part price.
How to specify quality documentation on a purchase order?
List the exact documents, drawing and specification revisions, customer forms, characteristic and sample coverage, required source evidence, submission timing and reviewer. Confirm feasibility and include the agreed requirements in the accepted order scope.
Does a certificate of conformance replace an inspection report?
No. A declaration and measured inspection findings have different purposes. If your receiving or approval team needs actual measured results, specify the relevant report and its coverage separately.
Can suppliers provide customer format quality reports?
Submit your actual templates and instructions during quotation review. The team can assess required fields, measurement or source evidence, signatures and submission requirements. Any unavailable element or additional work needs agreement before commitment.
Are FAI, ISIR and PPAP the same?
No. FAI and ISIR concern the defined initial-sample evidence, with content governed by the applicable requirements and agreed format. PPAP is a customer-defined production approval submission with its required elements. Specify the intended process and requirements rather than treating the names as interchangeable.
Does a Control Plan prove inspection was completed?
No. A control plan defines the agreed controls and reaction instructions. Actual inspection or process records document execution and findings. Review both where required; neither a blank plan nor a sample template proves your parts were inspected.
