In tomato juice or sauce? Looking for tomatoes in juice.

The label says "peeled tomatoes" which is what is in the can. There is fluid in the can that is juice from tomatoes but this is not tomato sauce.

Are they really BPA free?

I only know what they claim on their website, which is that they have not used BPA as a coating since 2014, I have no technical means or skills to test the cans. But I don't eat enough canned Cento tomatoes to worry about it even it the can did have some BPA in it. I make marinara or pizza sauce a few times a year. I think of BPA as more of a problem in plastic containers like water bottles.

Are these tomatoes organic? I see organic in the ingredients on the page but not on the can label.

These come in both organic and regular. The ones you refer to are not organic and looking at the product description and the label on one of the cans I ordered, I don't see any reference to Organic. If you want organic, order these: https://www.amazon.com/Cento-Marzano-Organic-Peeled-Tomatoes/dp/B0045W29XK/ref=pd_day0fbt_img_sccl_1/143-6446685-3579603?pd_rd_w=k9nbE&content-id=amzn1.sym.b7c02f9a-a0f8-4f90-825b-ad0f80e296ea&pf_rd_p=b7c02f9a-a0f8-4f90-825b-ad0f80e296ea&pf_rd_r=4D45HM288M791E9CGXNZ&pd_rd_wg=Q9cnw&pd_rd_r=9dd092c7-e0ca-4f55-9f0e-540b8a782da3&pd_rd_i=B0045W29XK&psc=1
