Identity: name, CAS and formula
Confirm product name matches PO, CAS number matches the SDS (e.g. HCl CAS 7647-01-0, PAC CAS 1327-41-9), and molecular formula/grade matches what you jar-tested. Mismatched CAS is a red flag for wrong material or relabelled stock.
Assay, impurities and heavy metals
Check assay/purity against your specification (e.g. HCl 30–33%, PAC Al2O3 %). For acids used near food/pharma utilities, review heavy metal and iron limits. Request MSDS alongside COA — Drashti’s product pages gate COA/MSDS requests behind business email for lead-verified document delivery.
Batch, date and GST paperwork
Match batch/lot number on COA to drum/bag labels. Note manufacturing and retest dates. Keep GST invoice (Drashti GSTIN 24AGLPC6288M1ZX) with COA for audit trails — especially for export and regulated plant stores.
