7 documentation gaps that delay Indian CRN applications (and how to avoid them)
Published 16 June 2026
Most CRN delays have nothing to do with the regulator being slow. They happen because the submission arrives incomplete, and every gap triggers another review cycle. After preparing many India-to-Canada registrations, the same handful of gaps come up again and again. Here they are.
1. Missing or mismatched design data
The drawing says one design pressure; the calculation assumes another; the data sheet lists a third. Reviewers stop the moment numbers do not reconcile. Fix: lock a single design data sheet (pressure, temperature, MDMT, corrosion allowance) and make every document agree with it.
2. Material grades that are not ASME-listed
India-sourced plate, pipe and forgings are often supplied to IS or EN grades. The Canadian authority needs ASME Section II-listed materials or a documented equivalence. Fix: verify every pressure-part material against ASME Section II before submitting, and document substitutions.
3. No MDMT / impact-test justification
Canadian sites get cold. If your design does not address the Minimum Design Metal Temperature and UCS-66 impact-test exemptions, expect a comment. Fix: include the MDMT assessment up front.
4. An invalid or expired QC certificate
The quality-control program certificate is part of acceptance. An expired certificate, or one that does not cover the equipment scope, stalls the file. Fix: confirm your QC certificate is current and scope-appropriate before filing.
5. Wrong fitting category (for fittings/valves)
Submitting a fitting in the wrong CSA B51 category means the wrong evidence, which means rejection. Fix: classify correctly first. See our CSA B51 guide.
6. Missing statutory declaration
Some provinces and categories require a Declaration of Compliance. Leaving it out is an automatic round-trip. Fix: know whether your province/category needs one before you submit.
7. Registering in the wrong jurisdiction
Equipment headed to Alberta filed with the wrong authority, or a single-province filing when a national pathway would have been cheaper and broader. Fix: map the jurisdiction before anything else.
The shortcut
Every one of these is avoidable with a document review before submission. That is the first thing we do for clients: review what you have, tell you exactly what is missing, and only then start. It is why our packages tend to clear review without the back-and-forth.
