Fibreglass Heat Mats

Hi there,
I’m looking for the HS code for fibreglass heat mats (aka plumbers heat mats, soldering mats) and more to the point, whether this item is subject to Anti-Dumping Tax?

I should add - there are coming from China.

Any help greatly appreciated.

Regards,
GW0580

Export 7019.31.00.90 from China to the United Kingdom

The above shows
Third country duty 7.00%
Definitive anti-dumping duty 19.90%
Definitive countervailing duty 10.30%
