What documentation should a legitimate refrigerant supplier provide?
The set, and what each paper proves
| Document | What it proves | Notes |
|---|---|---|
| Manufacturer SDS | Real product identity; hazard and handling data | Current version, exact brand (SDS guide) |
| GST tax invoice | Lawful sale; traceable seller; input credit | Should name brand, product and quantity — not "gas, misc." |
| Batch number / COA | Traceability to a manufactured lot; purity basis | Where the brand issues them; reconcile with cylinder label |
| ODS seller registration (R-22 only) | Lawful HCFC sale under Rule 6 | Number + date — ours is ODS/CS/17/6(12)/2024-OC, 12.11.2024 (how the rule works) |
| Buyer declaration (R-22, your side) | Rule 7 compliance on the purchase | Schedule XII — a diligent seller asks (details) |
Reading the set as a fraud filter
Each document is forgeable alone; the reconciled set is hard to fake. Brand on the invoice must match the SDS must match the cylinder label must match the batch marking — and the seller's registration must be real and current (verification steps). Gaps have meanings: no SDS suggests no brand relationship; a vague invoice suggests off-books stock; refusal on the ODS certificate for R-22 is disqualifying outright. The full inspection logic sits in genuine vs counterfeit.
Why the file pays for itself
Three audiences will eventually ask for it. Auditors and inspectors — EHS, fire, GST — expect SDS availability and clean purchase records. OEMs and insurers — a compressor-failure claim goes better when the gas trail is documented. Your own diagnostics — batch identity turns a suspected bad cylinder from an argument into a lab query. Filing cost: minutes per consignment. Recovery cost without it: open-ended.
What we hand over, as standard
Every consignment: GST invoice naming brand and product; SDS supplied or on request for all lines; batch identity where the manufacturer provides it; and the ODS registration published permanently on the compliance page rather than produced on demand. For AHRI 700, our claim is deliberately precise: we distribute factory-sealed product from brands that publish conformity — we do not run a lab, and a supplier who claims otherwise should show you theirs (what the standard means).
Building the purchase file: a one-page system that survives audits
Documentation fails in practice not from absence but from scatter — the invoice in accounts, the SDS in an inbox, the declaration nowhere. The fix is a per-consignment discipline cheap enough to actually happen: one folder (paper or digital) per delivery, opened when the order confirms and closed when four items sit inside — the GST invoice naming brand, product and quantity; the SDS current for that exact brand; batch identity (cylinder-stencil photo takes ten seconds and beats transcription); and, for R-22, the Rule 7 declaration copy alongside a copy of the seller's ODS registration. Index folders by date and supplier, and the system is complete. What it buys, concretely: EHS and fire inspections pass on production of SDS and licence copies rather than on promises; GST scrutiny matches inputs to documented purchases without archaeology; warranty claims on failed compressors survive the OEM's first question — what gas went in? — with batch-level answers; insurance and incident reviews reconstruct the chain in minutes; and internal quality gains a memory, because a suspect cylinder traced to batch and supplier is a solvable problem where an undocumented one is only an anecdote. The mirror-image test also works: run the same standard against your suppliers, and the ones whose paperwork arrives complete and unprompted — the standard we hold ourselves to on the compliance page — are the ones whose product needs the least checking.
