The CITES musical-instrument certificate originated at CoP16 (Bangkok, 2013), but the specific adoption day is still unverified

CITES's own CoP16 plenary record (CoP16 Plen. 7 (Rev. 1)) confirms, in the document's own words, that the meeting was the "Sixteenth meeting of the Conference of the Parties / Bangkok (Thailand), 3-14 March 2013" — Tier-1 confirmation that the musical-instrument certificate mechanism, first established as Resolution Conf. 16.8, originates at that meeting. This grounds the "CoP16, Bangkok, 2013" half of the claim recorded (but flagged) in claim-cites-musical-instrument-passport-certificate.

What remains unconfirmed is the specific single day, "13 March 2013," attributed in a Tier-3 trade-press account (Fretboard Journal, citing USFWS's Tim Van Norman) as the certificate's adoption date. The CoP16 plenary session closest to hand in this search — the seventh, 14 March 2013 — covers species-listing votes and does not mention Resolution 16.8 or the musical-instrument certificate by name; the working document that likely names the actual adoption session (CoP16 Doc. 40 (Rev. 1)) could not be fetched (403, no Wayback snapshot found). Separately, the resolution now in force is explicitly titled "Conf. 16.8 (Rev. CoP17)," amended at the 17th meeting (Johannesburg, 2016); this session could not confirm which, if any, provisions changed between the original 2013 text and the version now in force.

Net: CoP16-as-origin is Tier-1 confirmed; the single day and the pre/post-Rev.-CoP17 continuity remain [unverified-quant — needs primary].
