When did Spanish language on labels become a requirement in the US?

I can't seem to find this info, including a search on this forum. I did find one post that indicated it might be post-NAFTA (so mid-90s). Is that correct?

I have an India rayon hippie dress that does look rather 70s but the label is in English, French and Spanish. It has US RN and Canadian CA numbers. Maybe I will post pics when I take them for opinions, I am suspicious it might be more 90s-ish.

 

It's not a requirement. Usually the languages are for the countries where they will be distributed/sold.

 

OK thanks. Here are some photos of the dress/labels if anyone can give me opinions on dating. My first thought was 70s but some things are making me doubt. Thoughts welcome! I did find out the company began in 1975 and is still active today. This style doesn't look like their current ones, but I'm just not sure if it's 70s or later.

 

This looks like a mid-late 90s babydoll. It’s the waistline. Can’t tell anything from personal experience with the label, but this combo style of hippie/babydoll has come into and out of fashion, mass and small produced imports sold at places on Haight street in San Francisco, Melrose in LA and Hawthorne in Portland - with fair regularity from mid 90s through now.

 

Thanks so much. That's what I suspected, appreciate the confirmation.

 

That's a very interesting clue and one I'll tuck away for the future.
