The US 25-Year Import Rule: A Complete Guide for UK Sellers and Buyers

Under US federal law, any vehicle that is at least 25 years old, measured from its date of manufacture rather than model year, is exempt from Department of Transportation (DOT) safety standards and Environmental Protection Agency (EPA) emissions requirements. This means a right-hand-drive UK car built in January 2001 becomes eligible in January 2026 without any need for costly compliance modifications. Before this threshold, importing a non-federalised vehicle usually requires working through a Registered Importer (RI) under the NHTSA's show-or-display programme, which is expensive and slow. The 25-year exemption is the route most UK sellers and American buyers rely on for classic Land Rovers, Jaguars, MGs and other cherished British metal, and it sits alongside our customs clearance process guide as essential reading before you commit to a sale.

US Customs and Border Protection (CBP) uses the manufacture date shown on the vehicle's VIN plate or build sheet, not the registration date on the V5C. This distinction matters because many cars built in late one year were first registered the following year, which can shift your eligibility by several months. If your paperwork is ambiguous, obtaining a heritage certificate from the manufacturer or an official dating letter from a marque club (Jaguar Daimler Heritage Trust, MG Car Club, etc.) is the safest way to satisfy CBP officers at the port of entry. We recommend securing this documentation before booking transport, since delays at destination ports incur demurrage charges that quickly erode any savings from shipping early.

At minimum you will need the original UK V5C logbook (or a certified copy if the vehicle has already been exported and deregistered), a bill of sale showing purchase price in GBP, the bill of lading issued by the carrier, and CBP form 7501 (entry summary) which your customs broker will typically prepare on your behalf. If the car has aftermarket modifications, keeping receipts helps demonstrate the vehicle's history if questioned. EPA form 3520-1 and DOT form HS-7 still need to be filed even for exempt vehicles — you simply tick the box confirming the 25-year exemption rather than declaring compliance.

Passenger cars imported into the US attract federal import duty of 2.5%, calculated on the purchase price converted to USD at the prevailing exchange rate — motorcycles and some pickup trucks have different rates, so always confirm your vehicle's HTS classification. On top of duty, expect a Merchandise Processing Fee (roughly 0.3464% of value, capped) and a Harbour Maintenance Fee if arriving by sea. Once the car clears federal customs it still needs state registration, and many states apply their own sales or use tax on the purchase price — California and New York in particular charge substantial state tax, so factor this into your total landed cost alongside our 2026 shipping cost breakdown.

Container shipping is strongly preferred for 25-year-rule classics because it protects the paintwork and interior from salt air during the two-to-four-week Atlantic crossing, and it allows the vehicle to be locked with personal effects such as spares or tools stowed safely inside (declared separately for customs). RoRo shipping is cheaper but exposes the car to the elements and handling by dock staff at both ends. Popular UK departure ports for East Coast US routes include Southampton and Tilbury, with typical transit to New York/New Jersey taking 10-16 days depending on the carrier and whether the route is direct or transshipped via Antwerp or Rotterdam.

While it is technically possible to self-file with CBP, most importers use a licensed customs broker at the port of arrival to handle the ISF (Importer Security Filing), entry summary, and duty payment. Brokers typically charge £150-£350 for a straightforward classic car entry and can flag any issues — such as an incomplete VIN dating letter — before the vehicle physically arrives, avoiding storage fees while problems are resolved dockside.

The most frequent mistake is assuming model year equals manufacture year; a '2001 model' badge does not guarantee a 2001 build date. Another is forgetting that hybrid or heavily modified vehicles may still need an EPA declaration even once past 25 years for emissions equipment tampering rules. Finally, always confirm your buyer's state DMV requirements for smog and safety inspection post-import — some states, like California, impose additional hoops even for federally exempt classics.
