Delays at customs can cost your business more than just time, they can disrupt supply chains, disappoint customers, and increase overheads. At Scanlon Freight, we help our clients move goods seamlessly across borders by ensuring they’re prepared for every checkpoint.

Here’s a step-by-step guide to avoiding common customs clearance delays, whether you’re importing or exporting.

Step 1: Get Your EORI Number(s) in Place

Before you can import or export goods, you’ll need an EORI (Economic Operators Registration and Identification) number.

  • UK EORI for UK customs declarations
  • EU EORI if you’re trading with EU countries post-Brexit

Tip from Scanlon Freight: Apply early. EU EORI numbers can take a few days depending on the country’s processing time. Need help? We can guide you through it or apply here at Gov.uk

Step 2: Provide Accurate and Complete Commercial Invoices

Your commercial invoice is the backbone of customs documentation. It should include:

  • Full consignee and consignor details
  • Clear and detailed description of the goods
  • HS (Harmonised System) codes
  • Incoterms (e.g., DDP, EXW)
  • Value and currency
  • Country of origin

Incomplete or vague invoices are a major cause of delays. We’ll check your documents before shipment to ensure compliance.

Step 3: Use the Correct HS Codes

HS codes classify your goods for customs and determine duties, taxes, and restrictions. Using the wrong one can lead to:

  • Incorrect duty payments
  • Delays at border control
  • Risk of penalties or inspections

Tip from Scanlon Freight: We can help classify your goods correctly. Don’t guess, get it right the first time.

Step 4: Understand Import Restrictions and Licensing

Some goods require import or export licenses, especially if they fall under categories like:

  • Pharmaceuticals
  • Chemicals/Dangerous Goods
  • Food & beverages
  • Electronics or dual-use goods

Tip from Scanlon Freight: We’ll flag any restricted items in your shipment and help secure the right permits.

Step 5: Choose a Trusted Customs Agent or Freight Forwarder

Having a professional partner like Scanlon Freight manage your customs declarations can save you time and stress. We:

  • Submit declarations on your behalf
  • Ensure data is accurate and timely
  • Liaise with customs if issues arise

Tip from Scanlon Freight: Don’t leave customs clearance to chance. A solid partner makes the difference between a smooth transit and a stalled shipment.

Step 6: Stay on Top of Duties, Taxes, and Payment Terms

Delays can occur if duties and VAT aren’t paid promptly. Consider:

  • Setting up a Duty Deferment Account
  • Ensuring your incoterms match who is responsible for customs payments
  • Budgeting for applicable tariffs based on HS codes

Tip from Scanlon Freight: We’ll help you identify what taxes apply and advise on efficient payment options.

Step 7: Track Your Shipment and Be Ready for Queries

Real-time visibility helps prevent surprises. Stay in contact with your freight forwarder and be ready to act quickly if customs request:

  • Additional documents
  • Proof of value or origin
  • Security declarations

Tip from Scanlon Freight: We provide proactive shipment updates and step in fast if customs intervention is required.
