Evaluation is split into Mandatory and Qualitative stages. Mandatory Criteria (gatekeepers): Must be met to proceed. Failure on any criterion disqualifies the bid. Criteria include: (1) Proof of valid ISO 17025 and ISO 17034 accreditation (laboratory chemicals). (2) Proof of being the manufacturer or a signed/stamped agreement with the manufacturer, traceable with full contact details (phone, email, address) and agreement duration (all categories). (3) For Reverse Osmosis: Group I Hazardous Substances Certificate or Company’s Certificate of Compliance under the Hazardous Substances Act. Qualitative Criteria: Weighted scoring for technical capability. Minimum 70% score required to pass. Scoring based on: (1) Submission of SDS and COA for at least 5 chemicals previously supplied (50% weight). Higher scores for more submissions (5+ = 50%, 4 = 40%, 2-3 = 20%, 1 or none = 0%). (2) Proof of past orders (50% weight): 5+ orders = 50%, 4 orders = 40%, 2-3 orders = 20%, 0-1 order = 0%. Note: SDS without COA (or vice versa) for the same chemical is not accepted. Middlemen without manufacturer confirmation letters are automatically disqualified.
