Hello @blurpje ,
Adding extra information on the shipping information will require some customization. I actually do not have the exact solution ready for your use but you can take a look at this answer that explains two different ways to add additional information along with product dimensions – https://stackoverflow.com/a/49258222
This is a fairly complex development topic. I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.
I can also recommend the WooCommerce Developer Resources Portal for resources on developing for WooCommerce.
You can also visit the WooCommerce Facebook group or the #developers
channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, as well.
If you need a paid solution, you can consider taking help from one of our partner’s website.
I hope this information helps.
Thank you ??
