Review material purity, technical documents and traceability requirements before agreeing an order.
Metals quality documentation — Ask the right document to answer the question.
Technical specification / TDS
Describes the stated material characteristics or agreed requirements. Check that the product, grade and revision match your enquiry.
Request a technical specification →Certificate of analysis / COA
Reports the stated analysis for an identified batch. Review batch identity, reported values, methods and limits relevant to acceptance.
Read the documentation guide →Safety data sheet / SDS
Provides safety and handling information for the relevant product. It is not a substitute for a batch analysis or technical qualification.
Request an SDS →Metals, oxides and specialist inputs.
Purity is only one part of quality.
Nominal purity grades are useful shorthand, but their interpretation depends on the analytical basis and which impurities are counted. Confirm the basis and the limits that matter to your process.
Material form, dimensions, particle size and other physical characteristics also affect acceptance. Provide the test methods and tolerances used by your organisation where applicable.
Document availability, release timing and the specific evidence accompanying an order are confirmed during the enquiry and quotation process. We do not present indicative specifications as batch test results.
- Identity & gradeMatch the product, formula, grade and specification revision.
- Batch informationConfirm the relevant batch or lot when reviewing analysis.
- Critical limitsReview impurities, units, detection limits and methods where relevant.
- Physical requirementsCheck form, dimensions, tolerances, powder characteristics and packing.
- Document scopeDistinguish a lot-specific result from a general data sheet, and confirm which documents will accompany the shipment.
Confirm the required evidence in advance.
Origin, production location and dispatch country are separate facts. Tell us what evidence your purchasing or import process requires for the offered material.
If independent inspection, sampling or weight verification is needed, raise it before the order is agreed. The scope, timing, location and responsibilities require confirmation for the supply.
Quality claims must be supported by the relevant material and documents. Company tax or registration records do not certify product purity, laboratory results or an ISO quality system.
Product photographs are references, not evidence of current stock, production capacity or a particular batch’s results.
