Can SMKlog sell me a label for the UK-to-US crossing?
No. Every quote this checkout returns starts from a US origin ZIP code, and a golf bag leaving a UK address never touches that system on the outbound leg. It travels on Royal Mail's own export product or a UK courier's international service instead. What changes once the bag lands in the US is that it is now inside a country our calculator does cover, which is the onward leg priced further down this page.
Do I owe duty on golf clubs shipped from the UK to the US?
It depends on whether the clubs are yours already or a fresh UK purchase. Under 19 CFR 148.31, a returning US resident brings personal and household effects taken abroad back in duty-free, and a golfer's own set that traveled with them on the trip qualifies. Clubs bought new in the UK are a separate question, covered by 19 CFR 148.33 below.
What if the set was bought new in the UK, not owned before the trip?
19 CFR 148.33 lets a returning resident bring back up to 800 USD in goods acquired abroad merely as an incident of the journey, duty-free, or 1,600 USD from certain US insular possessions. A single set of clubs bought at a UK pro shop usually clears under that ceiling; the exemption explicitly excludes anything bought for resale or on someone else's account.
Once the clubs clear US customs, what does it cost to send them on?
$64.23 to $111.27 for a 50x15x14 in, 34 lb hard travel case boxed after clearing customs, from Newark, NJ to Charlotte, NC, quoted 2026-08-21. That is the domestic forwarding leg our checkout actually prices; it is not the Atlantic crossing itself.
Who decides the duty owed on the clubs, the airline or customs?
US Customs and Border Protection, not whichever airline, courier or postal service physically carries the case. The carrier only collects on delivery what CBP has already assessed at the border; it has no say in which rule applies.
