#vendor-verification 2026-04-30

blinded is better

if the evidence is thin the entry says the evidence is thin. that is more useful than a score

is there a version of the log i can read chronologically

two labs a point or two apart on one lot is normal. both go in the log with both numbers

what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine

pattern not one result

i have watched this standard hold for three years including when it was inconvenient for a popular supplier
update from 19 months ago: QSC added evidence and the entry now reflects it

a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel

we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry

how do you handle a result that is good but the sample handling was poor

update from 11 months ago: ERP added evidence and the entry now reflects it

if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution

coming back after 22 months, has the standard changed

verification is not a recommendation. it means the evidence standard has been met, nothing more

we have never revoked on a single result. we have revoked on a pattern

never for sale

log it either way

nothing gets deleted

does a supplier certificate on its own count for anything

how does a supplier get verification revoked

how long does a verification stay current before it needs refreshing

Verification log updated: WXT — evidence added, status unchanged.

revoked stays in the log

a good result with bad sample handling gets logged with a note about the handling. context is part of the record

what actually counts as evidence for a verification

both numbers go in

blinded submissions carry more weight because they remove a variable, not because we distrust the labs

somebody once offered to fund the testing programme in exchange for an entry. the offer is in the log

thats evidence

does KP being verified mean my vial is fine

refresh on evidence

the mods maintain the log. the room supplies the evidence and argues about it, which is the correct division

a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both, i could be wrong

right so thats not evidence

what counts: an independent report, on a lot you bought yourself, with the lot number, from a lab the room recognises

why is a referral link disqualifying rather than just ignored
a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel

not a recommendation

a referral link is disqualifying because it makes the reporter an interested party. that is all

a supplier improving shows in the log as later entries, not as earlier entries being edited

the lot number on the certificate does not match my vial, what now

two labs disagree on the same lot, which one goes in the log

i have a result but i did not buy the lot myself, does that count
