Hello from the ECHO Florida Seed Bank! Each country has different import laws, but for Haiti, as listed on the USDA/PCIT website, all seeds except vegetable seeds require a phytosanitary certificate. Vegetable seeds do not require a phyto and they are unrestricted.
A phytosanitary certificate can be obtained from your local USDA Plant Inspection Station and this document costs around $61. You need to physically bring the seeds in to be inspected and they will issue you a phyto. Double check with your local inspection agent but normally the seeds can then be hand carried, or mailed, with the document.
If you are receiving seeds from ECHO and need a phytosanitary certificate, we can handle the acquiring of the document and the mailing of the seeds if you pay for the document fee. Just contact us at email@example.com. Some countries require an import permit as well, so just email us and ask about your specific country’s import laws. You may have had this experience where some countries have import laws but do not actively enforce these laws. We are happy to inform you of the legal process for your specific country if you are concerned.
