is it illegal to send seeds in the mail

Can you send plants through the mail?

Also, can you mail seeds to another country?

Similarly, how do you mail seeds? Small seeds such as tomato and pepper seeds to some extent can be sent in a plain envelope with something like a thick paper towel for padding. If there is more than one packet they need to be taped down so that they can’t get on top on each other.

Because most countries have regulations to protect against agricultural pests and diseases as well as invasive species, you will probably need both a phytosanitary certificate and an import permit to take or send your seeds to another country.

My understanding is that because the seeds themselves do not contain THC, they are technically legal to mail. The seed labeling is always marked something like “birdseed” or “for novelty only, do not germinate” or “for collection/preservation only, do not germinate where illegal to do so”.

In fact, according to the USPS mailing code, most plants are mailable within the United States, as long as the USDA does not prohibit them. Just make sure that you‘re gentle with the plant as you remove it from the soil. Package and ship the plant as soon as possible.

you’re okay on a federal level.

a. If the package is not classified as Express Mail� service (domestic or international), Priority Mail� service, First-Class Mail�, or an international letter package, it may be opened and its contents examined.

I’m sure your post office will clear it up for you.

I never mark my packages ‘seeds’. The reason I don’t is found here, further down in that section – they can’t open it and inspect it unless you’ve said they could, or they call you or the recipient and get your permission:

b. If the package does come within one of these stated classes (and is therefore sealed against inspection), it may be opened and its contents examined only if (1) the package displays on its exterior the sender’s statement that it may be opened for inspection; (2) the agricultural inspector telephones the addressee or sender, obtains his or her consent to open the package and examine its contents, and certifies on a form submitted to the Postal Inspection Service that such consent was obtained; or (3) when neither of the foregoing types of authorization to open and examine is available, a federal search warrant is obtained based on probable cause to believe that the contents of the package will evidence violation of the marking requirement of the Terminal Inspection Act.

Looks like to me it’s basically saying the outside package needs to identify what is inside. if it’s plants, write “Plants” on the package. if it’s seeds. you write seeds.

Most are imported, non-native plants (think kudzu) that might endanger local ecosystems.

The Single Convention on Narcotic Drugs from 1962 classifies marijuana as an illegal substance, but not marijuana seeds. This treaty was signed by 180 countries and it takes precedence over national laws in Europe, which makes weed seeds technically legal everywhere in Europe.

When packing seeds, do not simply put them inside a regular envelope. They will likely get crushed by the post office’s equipment. Put them inside a bubble type envelope or something similar, to ensure they are protected.


The same is true for seeds bought from an international seed bank. There is a minuscule chance they could be confiscated by customs, but if it does happen, you’ll simply get a note informing you of this. You will not be arrested.

Laws in the US are a mess. In some states, you can legally grow weed. In others, you can’t even smoke a tiny bit if you are dying from cancer and in tremendous pain.

We also get quite a few readers from Europe, with most of them being in the UK. There, you can legally purchase and sell cannabis seeds (but not germinate them, both domestically or from other European countries. In fact, many American buyers use long-established UK sellers, like Seedsman.
