I'll PM @prwillard2 with my Customs Broker's contact information. Heads up to everyone, though, she's in Baltimore so she might have her hands full. Not sure--I haven't talked to her since the bridge collapse. BTW, it's not necessary to use a Customs Broker that's physically present at the Port of Discharge--a broker anywhere should be able to clear your shipment through any US port.
Re: HTS codes, I had a quick look through them. Of course, there's no code that
exactly matches your cargo (it's kind of a unique item). At first I thought maybe it's like a camping tent, which falls under HTS code heading 6306 (
Tarpaulins, awnings and sunblinds; tents (including temporary canopies and similar articles); sails for boats, sailboards or landcraft; camping goods). Unfortunately, most of those goods are taxed at either 8% or 8.8%. Not ideal.
So then I thought, maybe it's more like a camper. The only campers I could find in the HTS codes are "slide-in campers", which fall under code 8708, and are taxed at 2.5%. Better. Or maybe it's a car part, which also fall under code 8708 and are also taxed at 2.5%.
Nothing I could find that's relevant is taxed at 0%. That's usually reserved for some farm equipment, or military goods, or in some cases goods that are imported from certain countries (I didn't see South Africa on the list).
In any case, you should probably all agree on how you're going to declare them on your HS-7. If somebody wants to dig through the codes, they're here:
hts.usitc.gov
Maybe there's something hidden in there that more closely matches what you've got.
