DUE DILIGENCE
Six checks before qualifying an alternative-origin source
Use the six checks as a sequence. A strong answer in one area does not replace missing evidence in another.
01Confirm the commercial counterparty
Record the legal supplier identity, its role in the transaction and the contact channel used for the inquiry. A company name, address or brand identity should not be treated as product-origin evidence.
Buyer checkCan the supplier and its role in this transaction be identified clearly?
02Confirm the product and grade identity
Match the offered product name and grade to the technical documents under review. Similar descriptions, shared application labels or origin wording do not establish that two grades are interchangeable.
Buyer checkDo the offer, technical documents and evaluation sample refer to the same product and grade?
03Verify origin evidence and its scope
Ask what evidence supports the stated origin and exactly what it covers: a product, lot, order, shipment or other defined transaction. Do not extend an origin statement beyond the scope shown by the evidence.
Buyer checkIs the origin evidence relevant to the material and transaction being evaluated?
04Review current technical documents and methods
Check the grade name, document revision, units, test methods and stated conditions before comparing values. Results produced by different methods or under different conditions may not be directly comparable.
Buyer checkAre the documents current for the grade, and are the comparison methods compatible?
05Define application and processing conditions
Describe the buyer's formulation or process, operating conditions, performance priorities and validation method. Grade suitability should be assessed against those conditions rather than inferred from origin or a generic application label.
Buyer checkAre the intended use conditions and acceptance criteria defined?
06Check document, lot and destination requirements
Identify which records are needed for qualification and how their identifiers relate to the material under review. Separately verify destination-market requirements using current official sources, the relevant product and origin scope, and applicable dates.
Buyer checkCan the evidence set be connected to the material and the intended destination?
