yes, it's retroactive. Anything sitting on a store's shelves will have to be compliant on Feb. 10th.
After Aug 14th they will have to have been third party lab tested to insure compliance.
If you're certain that your items are safe (by whatever means you deem to be "reasonable testing") you can still sell after Feb 10. Though a shipment of a wholesale order will have to include General Compliance Certificates.
She shouldn't order more than she can sell by Aug 14 though, unless you're conducting 3rd party testing on your batch.
