A. In the US it is basically accepted by all that cottonseed oil is not Kitniyos however in Eretz-Yisroel it is a matter of dispute. Those who hail from Chutz LaAretz can continue to keep with their Minhag from Chutz-LaAretz and use cottonseed oil as non-Kitniyos oil.
Q. How come some products switch their Hashgacha for Pesach or are only certified by one of their usual Hashgachos for Pesach?
A. Just like people different Hashgachos have different minhagim. It could be that one Hashgacha has a particular Minhag not to use a certain ingredient on Pesach while others can. Sometimes it may be an issue of Kitniyos therefore a Sephardic Hashgacha can certify it while an Ashkenazic Kashrus cannot. However sometimes it may be because of a more minor Minhag. In Israel there are Hashgachos that do not certify onion powder, garlic powder, and black pepper.

Q. why do so many dairy products say on them Kasher LePesach Erev Pesach?
A. Before Pesach if a negligible amount of Chametz falls into a Kasher Lepesach item it becomes nullified in the Pesach item.

Therefore there are many people that are careful to purchase products that were manufactured before Pesach.
