E‑Commerce Importing Guide: How Online Sellers Can Import Smoothly and Stay Compliant

Why E‑Commerce Importing Is Different
E‑commerce businesses face unique importing challenges. Unlike traditional importers, online sellers often deal with:
- High order volumes
- Fast‑moving stock
- Multiple suppliers
- Frequent small consignments
- Tight delivery expectations
- Complex returns processes
This guide breaks down everything e‑commerce importers need to know to stay compliant, avoid delays, and keep costs under control.
1. Understand Your Responsibilities as an Importer
If you import goods into the UK to sell online — whether on your own website, Amazon, eBay, Etsy, TikTok Shop, or Shopify — you are legally the importer of record.
This means you are responsible for:
- Correct HS/commodity codes
- Accurate customs values
- Paying duty and VAT
- Ensuring product compliance
- Keeping records for HMRC
- Handling returns and re‑imports
Even if your supplier “handles shipping,” you must still ensure compliance.
2. Get Your EORI and VAT Registration in Place
Before importing, you need:
- A valid UK EORI number
- VAT registration (if applicable)
- Access to CDS (Customs Declaration Service)
- A duty deferment account (optional but useful for high‑volume sellers)
Without these, your goods may be held at the border.
3. Classify Your Products Correctly
Correct HS codes are essential for:
- Duty rates
- VAT
- Import restrictions
- Product safety rules
- Origin eligibility
E‑commerce sellers often import:
- Clothing
- Electronics
- Homeware
- Beauty products
- Toys
- Accessories
Each category has strict classification rules — and mistakes can be costly.
4. Understand Duty and VAT for E‑Commerce
Duty and VAT depend on:
- HS code
- Customs value
- Origin
- Whether preference applies
- Whether you use postponed VAT accounting
Tip: Many e‑commerce sellers overpay duty because they don’t check origin rules or relief options.
5. Check Product Compliance Requirements
E‑commerce products often require additional compliance checks, such as:
- CE/UKCA marking
- Safety certificates
- Labelling requirements
- Chemical restrictions (e.g., REACH)
- Food or cosmetic regulations
- Toy safety standards
Non‑compliant goods can be seized or destroyed.
6. Ensure Supplier Documentation Is Accurate
Supplier errors are one of the biggest causes of delays for e‑commerce sellers.
Make sure your supplier provides:
- A correct commercial invoice
- Accurate product descriptions
- Correct HS codes (to be verified)
- Packing lists
- Origin statements (if claiming preference)
- Certificates for regulated goods
Provide suppliers with a documentation template to avoid mistakes.
7. Choose the Right Incoterms
For e‑commerce, the most common Incoterms are:
- DAP – You pay duty/VAT on arrival
- DDP – Supplier pays duty/VAT (often risky or non‑compliant)
- FOB – You control the shipping and customs process
Warning: Many DDP shipments are not compliant with UK customs rules.
8. Plan for Returns and Re‑Imports
E‑commerce returns are high — often 20–40% depending on the product.
Use Returned Goods Relief (RGR) to avoid paying duty twice when:
- Customers return items
- Goods are re‑imported in the same condition
- You can prove original export
This can save thousands per year.
9. Understand Fulfilment Options
E‑commerce sellers often use:
Fulfilment by Amazon (FBA)
You must ensure:
- Correct customs declarations
- Accurate product compliance
- Correct valuation
- Proper record‑keeping
3PL Warehouses
Ensure your warehouse:
- Understands customs requirements
- Tracks stock accurately
- Supports returns and RGR
Direct‑to‑consumer shipping
Ideal for small sellers, but customs compliance still applies.
10. Avoid Common E‑Commerce Importing Mistakes
Many online sellers run into issues because they:
- Use incorrect HS codes
- Rely on supplier declarations
- Don’t check product compliance
- Misunderstand DDP shipments
- Fail to claim duty relief
- Don’t keep proper records
- Ignore port‑specific requirements
- Don’t prepare for returns
A structured process prevents these costly errors.
