Frequently Asked Questions
Q: Do I need a US export licence to import to the UK? A: Most products don’t require export licences, but dual-use technology, defence items, and some food products may need US Commerce Department or other agency approvals.
Q: Can I import goods worth less than £135 without paying duty? A: No, the £135 de minimis threshold was removed for business imports. All commercial imports are subject to customs procedures regardless of value.
Q: How long does UK customs clearance take for US imports? A: Standard clearance takes 2-6 hours for document checks. Physical examinations (5-10% of shipments) can add 1-3 days depending on complexity.
Q: Do I need insurance for imports from the USA? A: While not legally required, marine cargo insurance is strongly recommended. Most trade terms (CIF, CIP) include insurance, but check coverage limits.
Q: Can I use DDP (Delivered Duty Paid) terms with US suppliers? A: Yes, but ensure your US supplier understands UK customs procedures. Many prefer DAP (Delivered at Place) to avoid UK import compliance responsibilities.
