Don't know if this has been posted before, but a similar debate was held on the softball site about ASA stickers.

This is directly from the NFHS web site:

NFHS Baseball Rule
1-3-5 Ball Exit Speed Ratio (BESR) Sticker Position Statement
For purposes of being able to identify non-wood baseball bats that meet the Ball Exit Speed Ratio (BESR) performance standard, bats bearing the certification mark as a sticker or decal are deemed in compliance, as long as the bat manufacturer provided the sticker or decal to the bat owner.

"as long as the bat manufacturer provided the sticker or decal to the bat owner."

As an official standing along side of the dugout inspecting the bats, how do I know where that sticker came from?

Yes it has:

Looks like you never got an answer.

Oh by the way, want to buy some stickers, $10.00 a doz. ??????????????

Doesn't matter to me where sticker came from. My job is to be sure that the bat has BESR markings. I had a team with no legal catchers mask this week(no NOCSAE markings at all). They told me that they had played used all year and no umpire had said anything about it. I threw it out and they had to borrow one from the other team. I will be bringing that up at our weekly association meeting tonight. Only problem with that is the only people at the meeting are the one's who care.

Rule 1-3-5 > 1/1/2003
 

According to Fed rule 1-3-5 on page 14, "Beginning January 1, 2003, all non-wood bats shall meet the Ball Exit Speed Ratio (BESR) performance standard, and such bats shall be labeled with a silk screen or other permanent certification mark."

With that said, how would a stick-on or adhesive label be considered "permanent"?

I'll readily admit that I'm very new to NFHS or Fed rules, but isn't permanent "permanent"?
