PostNL Shipping Services for shipping to the UK
- PostNL lets you send parcels abroad, with a variety of options (standard, express, insured, registered) to suit different needs.
- Their international parcel service starts from about €7,95 (for smaller/cheaper shipments) for many destinations.
- Parcels can be prepared online (you create and print the label) or taken to a PostNL point, where they’ll help with the label and customs forms.
Parcel Sizes and Weights
- Letterbox parcel: Up to 2 kg, max dimensions 38 × 26.5 × 3.2 cm.
- Small parcel: Up to 2 kg, sum of length, width, and height: up to 90 cm; longest side up to 60 cm.
- Medium parcel: Up to 23 kg, max dimensions 100 × 50 × 50 cm.
Delivery Times
Delivery speed depends on the service level. Standard shipments take longer, while priority options arrive faster. PostNL notes that customs checks in the UK can cause extra delays. They also publish international service alerts if disruptions occur.
Customs and Handling
Since the UK is outside the EU, customs forms are required. PostNL helps with clearance, but the recipient may need to pay VAT, import duties, or handling fees. If extra info is needed for customs and is not provided, the parcel may be returned.
Restrictions
Some items cannot be sent abroad, such as aerosols, lithium batteries, and live animals. All parcels must have a barcode label for tracking. Sending goods with stamps alone is no longer allowed.
Customs and Brexit Considerations
Brexit has changed the way parcels move to the UK. The UK is now outside the EU, so every shipment must go through customs. This adds paperwork and sometimes extra costs.
- Customs Forms and Documentation
All parcels to the UK need a customs declaration. PostNL requires you to fill out the contents, value, and purpose of the shipment. You can create these forms when you print your shipping label online or at a PostNL point. Without these documents, parcels may be delayed or returned.
- VAT and Duties for UK Buyers
UK customers may need to pay import VAT, duties, and handling fees before their parcel is delivered. The exact amount depends on the product type and value. Shopify merchants should make this clear at checkout to avoid surprises for buyers.
- Tips to Reduce Delays
- Fill out customs forms accurately and in detail.
- Use clear product descriptions and correct HS codes.
- Include invoices inside the package when possible.
- Let customers know they may have to pay VAT or duties.
By preparing documents properly and keeping buyers informed, you can reduce customs issues and keep delivery times predictable.
Shopify Integration with PostNL
To use PostNL for UK orders, merchants need a shipping app. These apps make it possible to create labels and send tracking updates automatically.
Connecting PostNL to Shopify
One of the easiest ways to link PostNL with Shopify is through the PH Multi-Carrier Shipping Label app. This app supports PostNL alongside other carriers. It lets you print labels in one click and manage orders without leaving Shopify.

This setup keeps the entire process from checkout to delivery smooth for both merchants and customers.
