Inquiry regarding LCL import of DG power banks from Shenzhen, China to Incheon

I would like to import DG (Dangerous Goods) power banks from Shenzhen, China to Incheon via LCL, but every company I have inquired with has responded that it is difficult. If there is anyone who can handle LCL imports of DG power banks from Shenzhen to Incheon, please let me know.
