Sugar

Opening never extends a date: if the packet date comes sooner, go by that. Estimates for quality, not a safety ruling. What the dates mean

Sugar keeps for about 2 years in the cupboard, counted from when you buy it. That's SnapLarder's estimate for sugar in general. If the packet has a date, go by the packet: it's specific to that product.

Some bags of sugar have no date at all: UK labelling rules don’t require one, because sugar kept dry doesn’t go off.

How long does sugar last once opened?

About a year. Opening never extends a date: if the date on the packet comes sooner, go by that.

Does sugar have a use-by date?

Usually not. Sugar normally carries a best-before date, which is about quality rather than safety. Stored as the label says, it’s usually still safe after it, though it may not be at its best. Use by vs best before

Can you freeze sugar?

There's no need. Sugar already keeps for about 2 years in the cupboard.
