What Is Customs Clearance?

Customs clearance is the process of getting your goods approved by UK customs (HMRC) so they can enter the country legally. It involves:

Until clearance is complete, your goods sit in a port or airport customs zone.

What Paperwork Do You Need?

  1. Commercial Invoice — Shows what you're buying, from whom, and for how much.
  2. Packing List — Lists what's in each box, weight and dimensions.
  3. Bill of Lading / Air Waybill — Proof of shipment from the carrier.
  4. EORI Number — Your UK business import ID. How to get one.
  5. Commodity Code — The HS code for your product. How to find it.
  6. Certificate of Origin — Sometimes required for preferential duty rates.
  7. Import Licence — Required for restricted goods (food, chemicals, electronics, etc.).

The Customs Clearance Process Step by Step

Step 1: Arrival. Your shipment arrives at a UK port or airport.

Step 2: Pre-clearance (optional). A good forwarder submits the declaration before the goods arrive, speeding things up.

Step 3: Declaration submitted. Your broker or forwarder submits the customs declaration via CDS (Customs Declaration Service).

Step 4: Duty and VAT payment. If not using Postponed VAT Accounting, duty and VAT are paid at this stage.

Step 5: Customs check (if selected). HMRC may inspect the shipment. This is random or risk-based.

Step 6: Release. Once cleared, the goods are released for delivery to your warehouse.

Tips for Smooth Clearance

  1. Use a reputable forwarder who submits declarations early.
  2. Get your paperwork right the first time — don't guess at codes or values.
  3. Be accurate on your commercial invoice — under-declaring value is fraud.
  4. Check if your goods need a licence before you ship.
  5. Ask about pre-clearance — it can save days.
