Postal pause & Info re US Tariffs (not on the folders), etc.

Specifically, CBP isn't respecting USMCA certificates of origin with postal shipments. And because that would incorrectly trigger 35% duty, that effectively eliminates cheaper postal shipping, which was the best option for single orders and only option for PO Boxes.
So, if that was you -  pair up your order with friends if you can, to split our other courier shipping options, for a best cost per folder. UPS Standard is typically best value.
UPS/FedEx are available, as listed in your cart.

It's time to condense information for you on this, on those tariff changes increasing your cost of living.

• Good news: there are no US Tariffs on any music folders, no matter what the dollar amount. They are duty-free under the USMCA trade agreement. NEW: since August 29th, there is no 'de minimus' $800 threshold, so couriers MAY charge a brokerage fee. We have this solved with UPS for folders (by consolidating daily shipments so you have no brokerage fee) and we are expect customers using FedEx may be assessed a brokerage fee.
• On other items made overseas (e.g. ring adapters, magazine holders, stands, lights) do expect US Tariffs and related brokerage when: those items are bought individually, as a separate line item in your order (i.e. not bundled with a folder).

That's the full story.

And for completeness, two more things:
"International Orders"
We call an "International" order one which is shipped to any country that's not the USA or Canada. "International" orders, as ever, will have VAT and/or duty and any brokerage charges for importation added by your shipper.
Various other free-trade agreements world-wide help with reduction of duty, such as the CETA for Europe and CPTPP for the Pacific Rim, and we'll designate that in paperwork - we've shipped to 40 countries. Technically, your shipping Incoterms are "CPT".
