Why Customs Matter for Every International Shipment
Sending a parcel across a border means dealing with customs — the government authority that controls what enters and exits a country. Understanding how customs works can help you avoid delays, unexpected charges, and even confiscated goods. This guide covers the essentials every sender and recipient should know.
What Is a Customs Declaration?
A customs declaration is a document that describes the contents of your parcel, their value, and their purpose (gift, sale, personal use, etc.). Couriers like DHL require accurate customs declarations for all international shipments. For commercial shipments, this is typically a Commercial Invoice; for personal gifts, a CN22 or CN23 form is used.
What to include on a customs declaration:
- A clear, specific description of each item (e.g., "men's cotton t-shirt" — not just "clothing")
- The quantity of each item
- The value in the currency of the origin country
- The HS (Harmonised System) tariff code, where required
- The reason for export (sale, gift, personal use, return)
Duties and Taxes: Who Pays?
Import duties and taxes are charges applied by the destination country's government. They are typically calculated based on the declared value of the goods and their HS code. Depending on the shipping terms agreed between sender and recipient:
- DDU (Delivered Duty Unpaid): The recipient pays duties and taxes upon delivery or collection.
- DDP (Delivered Duty Paid): The sender or courier pre-pays, and the recipient receives the parcel with no additional charge.
Many e-commerce platforms now offer DDP shipping to improve the customer experience — especially since unexpected customs bills are a common cause of parcel refusals.
Common Reasons for Customs Delays
- Incomplete or inaccurate documentation — missing values or vague descriptions
- Under-declared value — customs authorities may inspect and re-assess
- Restricted or prohibited items — every country has its own list
- Missing HS codes on commercial shipments
- High volume periods — customs offices can experience backlogs during peak times
Prohibited and Restricted Items
Some items cannot be shipped internationally at all; others require special permits or licences. Common examples include:
| Category | Examples |
|---|---|
| Prohibited (universally) | Dangerous goods, narcotics, counterfeit goods, live animals (most) |
| Restricted (country-specific) | Alcohol, tobacco, food items, medicines, batteries |
| Requires permits | Firearms, cultural artefacts, certain plants and seeds |
Always check the destination country's import restrictions before shipping. DHL provides a country-specific prohibited items guide on their website.
De Minimis Thresholds: When Are You Exempt?
Most countries have a de minimis threshold — a value below which goods can be imported without paying duties or taxes. These thresholds vary widely by country:
- USA: USD 800
- European Union: €150 for customs duty; VAT applies from €0
- UK: £135 for customs duty; VAT applies from £0
- Canada: CAD 20 (very low)
Be aware that thresholds change over time as governments update trade regulations.
Tips for Smooth Customs Clearance
- Always fill in customs forms accurately and completely.
- Use specific item descriptions — customs officials need to know exactly what they're assessing.
- Keep the declared value honest — under-declaring is a customs offence.
- Include a commercial invoice for any B2B shipment.
- Work with a courier (like DHL Express) that offers proactive customs clearance services.
Customs doesn't have to be stressful. With accurate paperwork and an understanding of the destination country's rules, most parcels clear customs without issue.
