Why Is My Parcel or Shipment “Stuck” in Customs? The Most Common Reasons and What You Can Do

One of the most common calls every customs broker receives usually sounds something like this:

“I was expecting a parcel and now it’s stuck in customs.”

If this has happened to you, you are definitely not alone.
Customs delays are quite common. However, there is always a specific reason behind them and, most importantly, there is usually a solution.

Let’s take a closer look at what actually happens when a parcel or shipment gets “stuck” in customs and what you can do to reduce delays and unnecessary charges.

What Does “Held in Customs” Actually Mean?

It does not necessarily mean there is a problem.

It simply means the shipment is undergoing customs clearance procedures in order to:

• verify the declared value of the goods

• review the shipping documents

• determine whether additional inspections or certifications are required

In many cases, the process is completed quickly and without any action required from the recipient.


The Most Common Reasons for Customs Delays

1️⃣ Missing or Incorrect Documentation

This is by far the most common reason for delays.

If any of the following documents are missing:

• invoices

• purchase receipts

• proof of payment

• accurate product descriptions

customs authorities may request additional information before clearance can proceed.

🚨 Even a very generic description such as “accessories” or “gift” may cause delays.


2️⃣ Declared Value Verification

If the declared value appears unusually low compared to the actual product, customs authorities may request:

• proof of payment

• order details / order confirmation

• bank transaction records or PayPal confirmation

The purpose is to verify the true commercial value of the shipment.

3️⃣ Ιnspection of Regulated or Restricted Products

Certain categories of goods require additional inspections or certifications.

Examples include:

• electronic devices

• cosmetics

• medical products

• food items

• battery-powered products

In such cases, additional authorities or regulatory agencies may become involved.

4️⃣ Missing IOSS Information for Low-Value Shipments

For online purchases imported from outside the EU, the IOSS system allows VAT to be paid at the time of purchase.

When:

• IOSS is missing

• or incorrectly declared

the shipment may require additional customs clearance procedures and charges upon arrival.

5️⃣ Ιncreased Inspection Volume or Courier Delays

The recipient or customs authorities are not always responsible for the delay.

Periods of increased shipment volume — such as Black Friday or holiday seasons — often create delays:

• in warehouses

• at sorting facilities

• or within courier and transportation networks.

What Can You Do to Speed Up the Process?

✔️ Keep All Required Documents Available

Make sure you have:

• invoice

• purchase receipt

• payment confirmation

• shipment tracking details

The faster these documents are submitted, the faster the customs clearance process can move forward.

✔️ Check Whether VAT Has Already Been Paid

On platforms such as TEMU, SHEIN, or AliExpress, VAT is often prepaid during checkout through the IOSS system.

If you are asked to pay VAT again, you may request a review of the charge.

✔️ Do Not Ignore Communications from Couriers or Customs Authorities

Many delays become longer simply because a required document or confirmation from the recipient is missing.

✔️ Consult a Customs Broker for Commercial Shipments

For commercial imports or higher-value shipments, proper preparation can help avoid:

• delays
• additional costs
• and unnecessary complications.

Professional customs handling from the beginning can make the entire process significantly smoother.

Conclusion

When a parcel gets “stuck” in customs, it is usually not something alarming.

In most cases, delays are caused by:

• incomplete documentation
• verification procedures or
• additional shipment inspections.

Proper preparation and timely handling of the process can significantly reduce both waiting times and unnecessary charges.
