UK Amazon LED panel light SI 2016 No. 1091 certification, LED wall light conformity statement

What should I do if electrical and electronic products are removed from Amazon UK? UK station: What certification is SI 2016 No. 1091? What certification is SI 2016 No. 1101?

Recently, many Amazon sellers have received the following emails:

Hello from Amazon Selling Partner Support,
Thank you for your message.
We are still missing a few documents required by Amazon policies.
Reply to this case with the following documentation for review in order to avoid reinstatement delays:
(a) EC Declaration of Conformity (This document can be obtained from the brand owner, EU/UK importer or EU/UK authorized representative) in line with applicable directives:
SI 2016 No. 1091
SI 2012 No. 3032
SI 2016 No. 1101
SI 2017 No. 1206
(b) Please be informed that in order to move forward with the approval process, you will need to update the EC Declaration of Conformity with the printed full name and the signature.
By applying to list these products, you certify that all materials you submit in conjunction with your application are true, authentic, and accurate. Note that Amazon may remove your listing privileges for failing to meet these requirements.
We appreciate your cooperation on this important matter.

Having said so much, what are these: SI 2016 No. 1091, SI 2012 No. 3032, SI 2016 No. 1101, and SI 2017 No. 1206! ? These are the instruction requirements corresponding to UKCA certification! That is to do UKCA certification! Why is the UK station like this? That's because of Brexit!

The United Kingdom announced that it will establish the UK Conformity Assessed (UKCA) system, which will replace the European General System CE Marking from January 1, 2021. To put it simply, it is sold in the UK (Great Britain – England, Scotland, Wales), to meet the requirements of the UKCA system, the goods must use the UKCA mark, and the CE mark will only be applicable to the EU from January 1, 2021. From January 1, 2023, UKCA certification will be mandatory, and now it is a transition period, but Amazon requires UKCA certification for electrical and electronic products, not the original CE certification.
