IATA Battery Shipping Regulation (BSR) 12 Edition could provide more direction when UN 38.3 tests based on cell/battery pack configuration, Whr, lithium amount etc.
* The 20 Wh exception only applies to data logger/cargo tracking devices not EV chargers. Each country and shipper can deviate from this, but it is good place to start.

Just detailing the batteries in the manual. Depending on the product we had primary or secondary cells in the products. A safety agency won't address the shipping boxes, which will need labels and proper documents. Most shipping companies divirt some amount of cargo through passenger airplanes. That is one of the reasons for the shipping boxes to be labeled. Back when the issue arose the FAA paid me a visit to make sure we understood the shipping requirements. Shortly after that I had to educate one of shipping companies on the requirements. I haven't had to deal with batteries for over 10 years. So I could be out of date.

We're pinging the battery vendor for UN 38.3 testing, just to be sure. The quote was quite respectable.

It’s highly likely the battery company already has a third part test report available. Just ask them for it.

Industrial partners have been flagging certain regulations (we have some very large, very conservative partners). The charger is for N. American residential applications, perhaps Mexico in the near future. Summarizing my findings after review of CFR Title 49, � 173.185 for shipping of hazardous materials. 1. 173.185, (a)(1) - all batteries must be proven proven to meet the criteria in, sub-section 38.3 of the UN Manual of Tests and Criteria (rev. 3, Amm 1). https://unece.org/fileadmin/DAM/trans/danger/publi/manual/Manual%20Rev5%20Section%2038-3.pdf 2. 173.185, (c)(1) Size limit exception - applies to “smaller” batteries where Watt-hour (Wh) rating may not exceed 20 Wh 3. 173.185, (c)(4) - air shipment packaging (and/or waybill) must be marked with the appropriate label/sticker and marked “UN 3481” ”[Lithium ion cells packaged in equipment] 4. The charger will comply with 173.185, (b) “Packaging” requirements by virtue of the cells being mounted on a PCB, which is in a metal enclosure. Here are my questions for any in the know: - per items 2. and 4., the charger itself does not need the Li-On label. - even given #2, it's a good idea to have the manufacturer test/certify their cells to 38.3, but is it required? thanks, and hope to see you at ISPCE in May!
