[Grammar] 'demand' or 'demand for'?

[Helissax]

[FONT=&quot]Please tell me which verb is better to use:

The company will demand for foodstuffs prices to be changed every nine months.
[/FONT][FONT=&quot]
The company will demand foodstuffs prices to be changed every nine months. [/FONT]

The problem is with the word "foodstuffs". Change that to "foodstuff".

 

[Barb_D]

Don't use "for" and omit the "to."

They will demand that prices be changed.

[FONT=&quot]The company will demand foodstuffs prices to be changed every nine months. [/FONT]

If you want to retain plural form of 'foodstuff', try this way with verb 'revise':
The company will demand the prices of foodstuffs to be changed/revised every nine months. Or
The company will demand a revision of the prices of foodstuffs in every nine months.
