Can I use H3 structural Pine for outdoor table top?

[backyardbac]

Bought this for making an outdoor table top since the dimensions were going to work well for my project https://www.bunnings.com.au/140-x-35mm-outdoor-framing-h3-treated-pine-3-6m_p8032245

Started taking a look at what to get to sand and stain it, since I want to flatten the surface and make it a darker colour. But then saw some comments on here saying you shouldn't sand it due to the chemicals in H3 treated pine?  Have I goofed up and bought the wrong wood for the job?  What are my options here?

Thanks

Have you cut the timber as yet? If not, then feel free to speak to one of the team at your store's timber yard about facilitating a return. One of our resident Bunnings D.I.Y. experts would also be happy to assist if needed. Let me tag @EricL who will be back on the site later today.
