How to upload the symbolic code of Bitrix in 1C?

Question

CMS

Good afternoon,

There is 1C-Bitrix: Site Management 12.0.3

There is a catalog of goods with handwritten import (apparently, religion does not allow the customer to convert to normal integration with 1C).
Each product has its own 36-digit code, unique among the entire catalog. This code is written in the "Character code" field of the Bitrix infoblock.

Goods are exported to 1C (by standard means), and I want this symbolic code to be transmitted to 1C as well.

Please help me to upload it there. I don't even know where to look for such a setting.

PS I can write the code in any other field, at the stage of handwritten import, this is not a problem

Well so there is a technical support. Reply within 6 hours. But they can’t upload from 1C through “exchange with the site”?
Is the code stored in the properties in the product in 1C?
