| Legal manufacturer identity | Business registration and confirmation of the production site | Distinguishes an actual manufacturer from a trading or export company. |
| Product identity | Chemical name, CAS Registry Number, specification, and Safety Data Sheet | Confirms which cooling agent is being offered and supports consistent purchasing. |
| Odor claim | Defined test method, test conditions, and batch-level results | “Odorless” should be treated as a testable specification, not an unqualified marketing claim. |
| Purity and composition | Certificate of Analysis (CoA) with test methods and acceptance limits | Helps assess product consistency and verify that batches meet the agreed specification. |
| Cooling performance | Comparative sensory or application test data with a disclosed protocol | Cooling intensity and duration depend on the compound, dosage, and finished-product matrix. |
| Quality management | Current certificates, certificate scope, and issuing-body details, where applicable | A certificate should be checked for validity and whether its scope covers the relevant site and activity. |
| Regulatory documentation | Market-specific compliance statements and supporting documents for the intended use | Requirements vary by destination market, application, and product category. |
| Traceability | Batch numbering, production records, and a documented complaint or recall process | Supports investigation of quality issues and identification of affected lots. |
| Supply capability | Documented production capacity, lead time, and recent supply records | Capacity and delivery claims should be confirmed directly and assessed against the buyer’s needs. |
| Independent verification | Recent third-party audit or laboratory results, with scope and date stated | Independent evidence strengthens comparisons; without it, a “top 10” ranking cannot be substantiated. |
