What buyer verification and returns are required when selling R-22?

Both sides of a compliant sale

The ODS Rules put duties on each party. The seller must hold a Rule 6 registration, maintain sale records, and file Form 4 returns so the state can reconcile national quota against actual sales. The buyer — when purchasing for stocking or a regulated end use — must hand over a Schedule XII declaration stating who they are and what the substance is for. A seller who asks you for a declaration is not creating friction; they are following the law.

What the paper trail looks like

The chain means an R-22 cylinder in India should, in principle, be traceable from producer quota through a registered seller to a declared buyer. That traceability is exactly what counterfeit product lacks — one reason document-checking doubles as an authenticity check (see what a legitimate supplier provides).

What this means for trade and industrial buyers

Technicians and AMC companies buying R-22 for servicing should expect to identify themselves and their use; pharma and industrial units buying HCFC-22 as feedstock operate in a separately-tracked lane with its own disclosures. Keep copies of your declarations and GST invoices together — auditors and environmental consultants ask for both, and a clean file is the fastest way through a compliance review. Our own registers and returns are maintained as required; details on the compliance page.

A worked example: one cylinder, start to finish

Trace a single R-22 purchase through the rules and the abstractions become concrete. An AMC contractor needs gas for a hospital's legacy chillers. Step 1: they choose a seller and ask for the ODS registration number — Rule 6 satisfied on the supply side. Step 2: because the purchase is for a regulated end-use, the contractor signs the Schedule XII, Part I declaration identifying themselves and the servicing purpose — Rule 7 satisfied on the demand side. Step 3: the sale is invoiced under GST with brand, product and quantity named, and entered in the seller's Rule 14 register the same day. Step 4: at the reporting interval, that register line flows into the seller's Form 4 return to the registering authority, which consolidates returns from all sellers for the Ministry — closing the loop between national quota and this one cylinder. Now run the same purchase through an unregistered channel: no declaration, no register entry, no return; the cylinder exists outside the quota system entirely, which is why enforcement treats unregistered sale as the gateway offence and why such stock correlates so strongly with counterfeit product. For the buyer the practical cost of compliance was one signature and a photocopy; the benefit is a defensible file when an environmental auditor, an insurer, or a warranty assessor asks where the gas came from. Keep declarations, invoices and SDS stapled together per purchase — the file audits itself.
