Supplementary Declarations

Accurate SSD submissions under CFSP and SCDP — never miss a deadline

Supplementary Declarations (SSDs) are the full customs entries that must be lodged after goods have been cleared at the border using a simplified procedure. Under CFSP and the Simplified Customs Declaration Process, traders have until the 4th working day of the following month to submit each SSD to HMRC via CDS. Late or incorrect submissions can result in penalties, suspension of authorisation and audit attention.

We handle the entire SSD lifecycle: data extraction from EIDR/inventory records, commodity-code classification, duty and VAT calculation, CDS submission, and reconciliation against your Final Supplementary Declaration (FSD). If you're behind on filings or facing an HMRC query, we can also handle catch-up and corrective entries.
