With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Similar to the law of Canada, the U.S. law (27 CFR 5.22 (g)) says that tequila must be "manufactured in Mexico in compliance with the laws of Mexico regulating the manufacture of Tequila for consumption in that country". Tequila cannot be sold in Canada at under 40% alcohol concentration (80 U.S. proof), while the U.S. only specifies a maximum alcohol content of 50.5%
text_B: If a more mellow 60-proof tequila was developed in Mexico, does this passage suggest that it could legally be sold in Canada (or at least, not mention any barrier to its sale in that nation)?
NO.
