Customs and trade support in the United Kingdom
TCSA supports UK customs brokers, freight forwarders, logistics operators, trade consultants and in-house compliance teams working on imports, exports and cross-border movements.
The UK market spans Great Britain and Northern Ireland. Customs treatment can differ between the two, and between movements to, from and through the European Union. Guidance linked from this page states the jurisdiction and movement type it applies to rather than treating the UK as a single customs regime.
