iptables udp question

I want to use iptables to change the udp incoming/outgoing to --Minimize-Delay

What is the command?

I saw this somewhere

iptables -t mangle -A PREROUTING -p udp -j TOS --set-tos Minimize-Delay
iptables -t mangle -A OUTPUT -p udp -j TOS --set-tos Minimize-Delay
iptables -t mangle -A POSTROUTING -p udp -j TOS --set-tos Minimize-Delay

but I run the commands and then do iptables -L and nothing shows....
