Are there are restrictions on shipping 16 oz bottles of fluid through the mail to the US or Canada? This is not corrosive or flammable.

Yes, there are size limits for sending liquids by mail, and the specific limits vary depending on the shipping company and the type of liquid. Generally, individual containers for liquids have size restrictions, and there are also limits on the total quantity of liquids that can be sent in a single package.

Individual Container Limits:
FedEx specifies that individual glass containers for liquids should not exceed 8 fluid ounces, while individual plastic containers can hold up to 16 fluid ounces.
Total Quantity Limits:
Some services, like the Post Office, have a maximum net quantity of 500ml/500g for liquids in any single parcel.
Specific Restrictions:
Certain liquids, like those that are flammable or dangerous, may have additional or stricter size limits or may not be permitted at all, according to DHL and Canada Post.

So there might be a problem if you go over the limit with a package when it crosses into the usa.

Years ago had to send a package of 12 4 oz non aerosol (but flammable) pump bottles to a place only accessible by plane. The service wanted them packaged in 3 boxes with an inspection prior to accepting as per above with major added fees. In the end the customer decided it wasn't worth the added expense.

CP is vague about this matter. Your best bet would be contacting them directly.

CP basic link on the topic.

From personal experience I would tape around lid then bubble each unit and double ziplock removing most of the air. Hopefully they are not crazy full. You have to expect expansion if items were to freeze in transit. Which can happen both by ground or pressurized air. Well cushion bottles in case of any drops. I would use a triwall box with cushioning around edge. Make sure to include arror up and note clearly on outer box liquids enclosed.

Are the bottles glass or plastic?
