TDS
Defines the released grade, indicative properties, applications and handling guidance. It is not a batch result.
Evidence library
Quality documents and company credentials
Documents are grouped by issuing party and purpose so buyers can distinguish company certifications, product testing and supplier batch inspection records.
Management-system certificates
ISO management-system certificates identify Huahai Feifei (Hebei) Concrete Admixture Co., Ltd.. They certify the stated management-system scope; they are not product certifications.
Current product-document workflow
Request the document set for the selected grade
Product documents are released by product, grade and available version. A company certificate, a historical test report and an upstream supplier batch report do not replace the current product TDS, SDS or order-specific COA.
Current TDS
Confirm the selected grade, revision and applicable technical limits.
SDS
Request the current safety document before handling, storage or transport planning.
Batch COA
Confirm batch-specific acceptance values with the commercial order.
Test evidence
Use only evidence that identifies the sample, method, date and issuing party.

SDS
Communicates hazards, handling, transport and emergency information for a named product and supplier.
Batch COA
Links a batch number to specification limits and actual test results. It does not replace application testing.
Application report
Records materials, method, dosage basis and measured results for a defined test—not a universal guarantee.
Before relying on a file: verify the legal company name, product/grade, document number, revision date, approval status and whether the document is current for the shipment.
