Import customs clearances are processed through different routes, depending on the commodity, the procedure, or random checks. Pre-lodged (not arrived) declarations are route H, and the following are the most common routes for live declarations:
Route 6 – This is a straightforward clearance and will proceed to clear as soon as taxes and any additional checks from border authorities are complete.
Route 1 – This requires that your documentation be sent to the National Clearance Hub for checks before they process the clearance.
Route 3 – This is a combination of route 1 and route 6, where the clearance is not postponed but the documents must be sent to NCH for checks.
Less common routes for UK customs clearance are:
Route 0 – This is where the DUCR (Declarant Unique Consignment Reference) has already been submitted to another government body, in order to electronically clear the consignment with them, but there is a query so a route cannot be assigned.
For example, if the weight declared to DEFRA on the PEACH/IPAFFS system is different to that declared on the declaration to customs.
Route 2 – This is an indication that customs require physical examination of your goods, as well as a documentation check.
