Your AcceptanceRetain material and part approval.
4 Ways to Define Your Material Supply
A Grade You Specify
Specified material machining starts with the full producer, grade, condition and drawing requirements. Agree who purchases the material and what evidence must accompany it.
Stock You Supply
For customer supplied material machining, review the actual blank dimensions, condition, identification, quantity, workholding allowance and required records before shipping.
Resin You Supply
For customer supplied material molding, identify the full resin and color, lot, packaging and handling history. Confirm tooling, process suitability and acceptance before sending material.
An Alternative for Review
Material substitution approval requires the full original and proposed products, affected requirements and recorded decision. A similar color, family or hardness is not approval.
Review Your Specified Material and Supply Route
Review Specified Grade for Your Drawing
For customer specified materials, retain the full manufacturer product, required standard, supplied condition and drawing revision. Agree the purchasing responsibility and material evidence before production planning.
| Your decision | What to confirm |
|---|---|
| Material identity | Full producer, grade, required standard, condition and lot |
| Supply responsibility | Who purchases or furnishes material; actual stock or resin |
| Acceptance | Controlled drawing, approved sample and required tests |
Confirm the Supply Scope
A specified grade and physical furnished material are separate decisions.
| Your decision | What to confirm |
|---|---|
| A Specified Product to Be Purchased | Agree the complete material, form, condition, quantities and evidence, plus the party responsible for purchasing. A customer specification defines a requirement; it does not by itself mean physical stock will be supplied. |
| Physical Stock or Resin You Furnish | Confirm the actual material, quantity, dimensions or packaging, identification, condition and available records before shipping. Agree receiving review, manufacturing allowance and handling requirements for the planned process. |
Agree Your Process Inputs
Retain the actual assembly, environment and measuring condition.

2 Supply Routes. Different Responsibilities.
A Specified Product to Be Purchased
Agree the complete material, form, condition, quantities and evidence, plus the party responsible for purchasing. A customer specification defines a requirement; it does not by itself mean physical stock will be supplied.
Physical Stock or Resin You Furnish
Confirm the actual material, quantity, dimensions or packaging, identification, condition and available records before shipping. Agree receiving review, manufacturing allowance and handling requirements for the planned process.
Resolve 6 Material Supply Risks
Identity & traceability for Your Finished Part
For plastic material traceability or another specified material, retain producer, full grade, lot, condition and the chain from received material to the job. Appearance alone is not a material certificate.
Received condition for Your Finished Part
For customer supplied plastic machining, review stock identity, dimensions, surface condition, damage and available material records. For resin, review packaging and material-specific handling history before process acceptance.
Allowance & quantity for Your Finished Part
How much extra stock should be supplied for machining? Review part geometry, blank layout, workholding, setup, first-piece approval and agreed process allowance. No universal spare-stock percentage is assumed.
Handling & process inputs for Your Finished Part
For customer supplied material molding, provide current product instructions and the material-specific storage or handling records. Agree process suitability and any required preparation; do not transfer one resin recipe to an unidentified product.
Substitution & approval for Your Finished Part
Can a material substitution be made without customer approval? Define the specified product, proposed change, affected requirements and recorded approval route. A generic equivalent label does not establish acceptance.
Remainders & disposition for Your Finished Part
Agree identification, storage period, reuse, return or approved disposal of unused material and scrap before processing. Keep the disposition decision tied to the material and job rather than assuming one default arrangement.

Answers Before You Specify
Can you manufacture parts from a customer specified material grade?
Send the complete product and condition, drawing, quantities and required records for a scope review. Confirm material availability or furnished-stock acceptance and process suitability before purchasing or shipping material.
Is customer specified material the same as customer supplied stock?
No. One defines the required material; the other defines who physically furnishes it. Agree purchasing, actual stock form and quantity, receiving review and required evidence separately.
What documents are required for customer supplied resin?
Provide manufacturer and full grade, color or additives, lot, available material certificate, current product and safety information, packaging and relevant handling history. Agree any missing evidence before process acceptance.
How much extra stock should be supplied for machining?
Review the blank layout, workholding, setup, first-piece approval, order quantity and agreed manufacturing allowance. Request a material plan for your drawing rather than applying a fixed percentage.
Can a material substitution be made without customer approval?
Do not assume a proposed alternative is approved. Record the exact change, affected drawing or material requirements, comparison evidence and agreed approval before processing.
How are unused customer materials and scrap handled?
Agree the identification, quantity record, storage period, reuse, return or approved disposal arrangement before work starts. Keep actual disposition and any required approval with the job records.
Retain the Full Material and Supply Agreement
| Reference | What it does and does not identify |
|---|---|
| Customer specified materials | The material requirement, including full grade and condition; does not by itself define who supplies it. |
| Customer supplied / furnished material | A supply responsibility requiring actual identity, condition, quantity and receiving review. |
| Material certificate for machining or molding | Agreed source evidence; keep it distinct from dimensional and functional part acceptance. |
| Approved alternative | A recorded material and scope decision, not an automatic equivalence based on generic description. |
Keep full product identity, supply responsibility and agreed acceptance separate. Do not treat a proposed alternative as an approved material change.
Generated concepts illustrate stock and part geometry. They are not actual customer-supplied materials, customer parts or company receiving records.
