How to use a checklist properly
Print it at the start, not the middle. The value is in seeing the whole list before you have committed money, because that is when the long lead times are still fixable.
Give it to whoever is actually doing the work. If your supplier is obtaining the certificates, the checklist belongs with them as much as with you. Half the items on most of these lists are somebody else's job.
Tick with a date, not a mark. "Done" tells you nothing three weeks later. "Done 14 Oct" tells you whether it is still valid, which matters because several of these documents expire.
The column that matters most
Every item is tagged with when it has to exist. Read that column before you read anything else. The items marked "before the goods ship" are the ones that cannot be fixed afterwards, and they are where nearly every stranded shipment goes wrong.
Why there is no email wall
The normal way to publish something like this is to ask for an email address first. I have deliberately not done that.
Everything else on this site runs entirely in your browser and sends nothing anywhere, and it would be strange to make the one printable thing the exception. If a checklist stops somebody paying for goods they cannot legally import, it should not have a toll on it.
If you find it useful and want the new tools as they land, the subscribe box below is there. It is a choice, not a gate.
These lists are a starting point
Requirements change with the product, the country, the agency and the year. Where a list says a certificate is needed for regulated goods, confirming whether YOUR goods are regulated is still a conversation with the agency or a licensed agent. The checklist tells you what to ask about. It cannot tell you the answer for your shipment.
