What documentation should a legitimate refrigerant supplier provide?

The set, and what each paper proves

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.
