In this age of terrorism, many post offices have become wary about sending anything though the mail that may be deemed dangerous. However,
It is safe and legal to send oil through the mail. If the post office insists that you pay for hazardous shipping, or that the sample must go by ground rather than air, please give them our post office letter. It explains how Blackstone's oil kits — and the oil itself — meets all US Postal Regulations. If they still resist accepting your sample, have them call us at 260/744-2380. We may not be able to change their mind, but we can try.
You might also try putting your sample in a padded envelope or small box and dropping it in a mailbox, so that it automatically goes into the system.
Postage for one sample is $2.41.
Send your sample to:
416 E. Pettit Ave.
Fort Wayne, IN 46806
We often receive samples from Canada, Great Britain, Australia, Mexico, and other countries without a problem. However, each country has its own rules and regulations regarding what can be sent through the mail.
If your country's post office won't allow you to send your oil sample through the mail, you might try giving them our post office letter. However, this letter only pertains to United States Postal Regulations. If your post office flatly refuses to accept the sample, try sending it via UPS or FedEx.
You should not have a problem sending your oil sample through the mail, as we regularly receive samples from other countries.
