Can I be penalized for calling a discard too slowly?

No. There is no penalty for calling too late. The call simply does not stand: you do not take the tile, your hand is not dead, and play continues. If someone tells you your hand is dead because you called late, they are wrong.

What actually closes the window

The window on a discard stays open until the next player picks a tile from the wall and then does one of these: racks it, names it, discards it, begins a joker exchange, or declares mah jongg.

Picking alone does not close it. If the player to your right has drawn a tile and is still looking at it, the discard is still live and you can still call it. Her picked tile goes back to the wall.

There is a precise definition of racked that matters here, because it is where most table arguments actually live. Racked means the tile has been placed on the sloped part of the rack with the rest of the hand. Tapping the rack with the tile, or clicking it against the rack while thinking, is not racking.

So what happens when you are late

Nothing happens. The tile stays in the discards, the next player carries on, and you keep playing your hand. Being late costs you the tile you wanted, which is the entire point of a timing rule.

This is worth knowing precisely, because there is a wave of heavy handed enforcement in the community at the moment and timing is one of its favorite targets. Players are being told their hand is dead over a late call. That is not the rule. Dead hands come from other things, such as playing out of turn or making an incorrect exposure, and a late call is not one of them.

The tile always goes to the caller, when the call is in time

Worth being precise, because these are two different situations and they get muddled. If your call is in time, the tile is yours. Even if the player to your right has already drawn from the wall, if she has not racked it yet, your call takes the discard and her tile goes back to the wall. If your call and her rack land at the same moment, you still get it. A timely call beats a pick, every time.

If your call is genuinely late, the tile is not awarded to anyone. It stays in the discards where it fell, play carries on, and you keep building your hand.

Settle the timing before you play, not in the middle of a hand

Almost every argument about this is not really about the rule. It is about nobody having agreed what racked looks like at this table. One player counts the tile touching the rack, another counts it sitting on the slope, and they are both certain.

So put it on the table before the first hand, the same way you would ask about any other house preference. How strict are we about the moment a tile is racked, and do we give a newer player a beat of grace? Ten seconds at the start saves the argument that would otherwise happen at the worst possible moment, with a tile everybody wants sitting in the middle.

If your group wants a stricter or looser standard than the written rule, that is entirely allowed. It is a house rule, and house rules are legitimate. They just need to be agreed out loud, in advance, rather than produced from memory halfway through a hand.

Where good players disagree

There is honest disagreement about how strictly to police the moment of racking, especially at a competitive table where a slow call genuinely changes what other people can do. Some groups treat the sloped rack literally, others allow a beat of grace for a newer player. Both are reasonable, and both work as long as everybody knows which one they are playing.
