I tried several times to buy some LFP out of the USA and 3/4's of the vendors will not even try to ship to Canada, some suggest doing the old trick of sending to the border like one of those UPS Storage Receiver places at the border and doing a pickup & drive across yourself dealio.... Not Happening with Covid Lockdowns. CBSA still see "Lithium" and they go stoopid and into semi-panic which does not help anything. I did try to get batteries from Big Battery and a couple of others when the BYD ESS batteries came available but never could get any arranged to be shipped up here so I gave up on it. LUCKY I DID TOO ! After the great rush on those BYD Packs and cells, it did not take long for all the reports of problems & issues started, so effectively Dodged a Bullet there. Can't imagine trying to ship that stuff back to USA for warranty... good gosh no....
You'll have to try each vendor and hope for the best BUT don't get your hopes up too much.
I've ordered & received quite a few cells directly out of China and no issues at all. Shipped DDP which includes duties, taxes, fees etc to the door. At first blush it seems expensive but when you work it out it isn't. The shipping time sux, because by boat can take up to 60 days. I've had cells shipped by Air Freight as well and that can get deep into the wallet but they can get here really quick.
NOTE: Due to Covid, a lot of stuff slowed down and it can result in pauses if something (port/shipper etc) get's closed due to it.
There are Canadian Suppliers and the numbers "look high" but remember the currency exchange ! Its a fricken bugger !
BTW: If interested, Amy Wan of Luyuan is one the best vendors we all know here and use for our supplies.
