The packaging of the product I received did not say 'Sea Grade' but it was an Ancor product. The entire cable tie package was so brittle that it broke about half the time I applied force to it. Even when I tried to tie a bow, the tie broke in my hands. Completely useless, I would choose another manufacturer. Maybe a marine grade product is better as I mentioned that the packaging I received didn't say "Marine Grade".
