“by when do you need it” is it the correct sentence asking someone for timeline?

That form is “correct” according to grammar nazis! But in practice nearly all Britons would ask “When do you need it by?”

The “rule” of not ending a sentence with a preposition was invented about 250 years ago by people with too much time on their hands, and too much regard for Latin forms, which were never in use in English.

No that is not correct. By is the same as when so it’s redundant.

When do you need it?

What is your deadline for needing this?

When do you need this?

this time i myself will make sure that you dont have to face any further delay and whole quantity reach you on committed date.

IS this sentence correct?

by what date do you need it? is probably a simpler way to get an exact answer.
