Not true. I got some from Australia recently with no problems.

But your asking an off label use of a chemical application on s public forum.
What more do you need educated on? The pros and cons of improper chemical exposures to your hives?
I have a Restricted Use Pesticide license and there is NO WAY I would attempt to do what you are considering doing.
The more I learn about bees, the less I know.
I wonder where the commercial bee business would be now after the failure of the EPA miticides which I think may have led to the CCD epidemic If it were not for the use of Tactic and other unregistered treatments. I would also mention the years of using OA.
i'm not sure why we are being selective on chastisement for using chemicals 'off label'.
prior to 3/10/2015 u.s. beekeepers using oxalic acid to kill mites in beehives were doing so illegally:
and for those in states that haven't approved it yet, like alabama for instance, it may still be 'illegal':
"Oxalic Acid has been approved by the EPA to treat honey bee colonies in the United States. It must pass state approval before it may legally be sold in each state."
and unless you are purchasing epa labeled oa from brushy mountain you may be in violation:
"Brushy Mountain Bee Farm has been authorized by the EPA to be the sole distributer of oxalic acid for use as a miticide on honey bees. What does this mean? Well, in order for any application of oxalic (in beehives) to be legal, it must have the EPA approval label on it; Brushy is the only distributor registered to use the EPA label. It may seem silly, but it really is there for a reason. If you start searching the internet for oxalic acid application in bees, there’s a broad range of information out there for recipes for taking straight oxalic acid (wood bleach) down to the 2 or 3%
(recommended) application concentrations. Some internet guidance may be sound, but others can be reckless – and even dangerous – for you and your bees. How can you know the difference? Certainly, you don’t want to risk gettng hurt or inflicting undue stress on your bees. An EPA label assures you of what you are receiving and gives you the applicable instructions to follow; so, you can avoid any gamble from following unsubstaniated YouTube videos. For example, the oxalic acid purchased at your local hardware store is only 95% pure oxalic acid. The material sold through Brushy Mountain Bee Farm is 99% pure."
i would venture to guess that there a number of contributors on the forum that might be guilty of having broken the law for these various reasons.
i don't have a dog in this fight because i don't use treatments of any kind, but i think we need to be a little less hypocritical here.
tedlemay, randy oliver is a pretty smart guy and he has stayed away from amitraz or anything like it that builds up residual biproducts in the comb that linger for a very long time.
your maqs is a lot more 'hive-friendly'. oxalic might be more cost effective if you do what most everyone else does and use unlabeled wood bleach, but then off course you would have to be constantly looking over your shoulder for the bee police.

Trying to justify off label use of Amitraz
Comparing it to OA use does not make a great case
just trying to figure out why some 'sins' are worse than others, and who gets to make that call...
OA had previous (~20 years) well tested usage in Europe and Canada without observed resistance development. The with-holding of approval in the US was due more to bureaucratic delay than safety or effectiveness issues, at least that is the general understanding.
In that light, I have no problem seeing that some "sins" really are worse than others. In reality we all make calls in what issues to follow to the letter of the law and which ones we observe with a bit of personal discretion.
>> "Brushy Mountain Bee Farm has been authorized by the EPA to be the sole distributer of oxalic acid for use as a miticide on honey bees."
I have no argument with that statement, but let us note that Brushy Mtn is not the exclusive vendor of Brushy Mtn EPA approved/labeled oxalic acid. At a minimum, Dadant is reselling Brushy Mtn labeled oxalic acid.

Not too long ago a beekeeper posted a pic of his nice looking broodnests on Facebook commercial page, which had blue shop towels visible in the pic. The comment section slammed him.
Yet guys post vids of OA vapour application all the time with great interest.
I think your just playing devils advocate but I do see your point. In Canada OA is registered, I did not realize it was not in the US
how is one supposed to know which issues get followed to the letter and which do not here? it seemed like a fair question that received an unfair response, but it appears i'm making too much of it, my apologies.
In Argentina, where amitraz has also been extensively used against varroa, a recent study suggests that mites in some operations have become at least 35 times more resistant to the chemical . Similar reports come from throughout the world (Italy, Portugal, Argentina, and France; reviewed by Pires ). Surprisingly, a friend in Chile tells me that amitraz failed to control mites there after only three seasons of use.
On the other hand, Semkiw , testing amitraz strips (similar to Apivar) in Poland, where the active ingredient has been used for 30 years, obtained up to 95% efficacy in eliminating varroa, with the majority of the mites dropping in the first three weeks, but full efficacy not obtained until 8 weeks.
Here in the States, Sammataro  found signs of varroa resistance to amitraz as early as 2003, wryly noting that “Surprisingly, mites also showed resistance to amitraz, which is not a registered acaricide.” And last year, Eischen  found resistant mites in some operations.
