Customs paperwork is one of the most critical parts of any international shipment, yet it’s also one of the most confusing. Whether you’re moving overseas for work, joining family abroad, or relocating for a long-term adventure, the paperwork behind your international shipment determines how smoothly your belongings pass through customs. Missing forms, vague inventory lists, incorrect valuations, or restricted items can delay your shipment for weeks. To avoid interruptions, it’s essential to understand which documents you need, how to prepare them properly, and what customs officers look for during the inspection process. With careful planning and support from professionals like United Local Movers, your customs paperwork can be handled accurately and efficiently.

Why Customs Paperwork Matters More Than You Think
Customs clearance is the gateway your shipment must pass through before entering a new country. Customs authorities examine your documentation to determine whether your belongings are allowed to enter, whether duties or taxes apply, and whether your shipment contains any restricted or prohibited items. Mistakes in this process are the most common cause of delays in international moving — not the ocean journey itself.
Here’s why customs paperwork is so important:
- Compliance: Each country has specific import laws and restrictions.
- Security: Customs checks for prohibited or dangerous items.
- Taxes and duties: Paperwork determines whether you pay import fees.
- Ownership confirmation: Documents must prove that your belongings are yours.
- Shipment release: Customs will not release your container without completed forms.
Understanding the documentation process helps you prevent mistakes and ensures your belongings arrive on time.
Essential Customs Documents Required for International Shipments
While specific requirements vary by country, there are several core documents you will almost always need. Having these prepared in advance — and completed accurately — is the fastest way to ensure smooth customs clearance.
1. Passport
Your passport proves your identity and must match all other documentation, including the Bill of Lading and your shipment inventory list.
2. Visa or Residence Permit
Some countries require proof of long-term residency or work authorization before allowing household goods to enter duty-free.
3. Detailed Inventory List
This is one of the most important documents in international shipping. It must be:
- Itemized
- Accurate
- Typed (handwritten lists often get rejected)
- Valued (showing approximate value of each item)
- Clear and descriptive (avoid vague labels like “miscellaneous items”)
Customs officials rely on the inventory list to screen items and verify that everything in your shipment is allowed.
4. Bill of Lading (BOL) or Air Waybill (AWB)
This document is issued by the carrier and serves as the official contract for transporting your goods.
- Shows destination port
- Container number
- Carrier information
- Shipment type (FCL, LCL, air freight)
Without the BOL or AWB, the shipment cannot be claimed at the destination.
5. Packing List
Different from the inventory list, the packing list details how goods were packed, including:
- Box numbers
- Weight per box
- Dimensions
- Description of contents
This helps customs verify physical goods against documentation.
6. Proof of Residency Change
Many countries require proof that you are officially relocating, such as:
- Housing contract
- Letter from employer
- Utility bill from the new address

Common Supporting Documents You May Need
Depending on your destination, extra documents may be required. These often include:
- Power of attorney for your moving company
- Import declaration forms
- Tax identification number (e.g., NIF, TRN, GST number)
- Customs exemption forms for returning citizens
- Vehicle import authorization (if shipping a car)
- Pet vaccination records (if relocating with animals)
Your moving company or customs broker will help you identify which additional documents you need based on your destination country.
How to Create a Proper Customs Inventory List
The inventory list is often the deciding factor for smooth customs clearance. A rushed or incomplete inventory increases the chance of shipment inspection, delays, and additional fees.
To create a customs-ready inventory list:
- Number every single box.
- List all contents for each box.
- Assign an approximate value to each item.
- Use clear language. Example: “Kitchen utensils” instead of “misc.”
- Note fragile or high-value items.
- Separate restricted or sensitive items.
TIP: Take photos of your items before packing. This helps with inventory accuracy and insurance claims if needed.
Restricted and Prohibited Items You Must Avoid
Each country has its own list of prohibited items, but here are universal restrictions you should never include in your shipment:
- Explosives, ammunition, weapons
- Aerosols (spray cans)
- Flammable liquids
- Lithium batteries (in certain shipping containers)
- Seeds, soil, plants, and fresh foods
- Chemicals and cleaning agents
- Alcohol above certain limits
Including prohibited items can lead to confiscation, fines, or full shipment delays.
How Customs Inspections Work
A customs inspection is a routine process where customs officers physically inspect your shipment to verify that documents match the contents. Inspections can be random or triggered by paperwork errors.
There are three main types of inspections:
1. Documentation Inspection
Customs checks paperwork without opening the container.
2. Partial Inspection
Specific boxes or sections of the shipment are checked.
3. Full Inspection
The entire container is unloaded and examined. This is rare but can happen if documentation is inaccurate.
Proper paperwork reduces the probability of a full inspection — saving time and money.
How Long Customs Clearance Takes
While timelines vary by country, these are typical clearance times:
- Air freight: 1–3 days
- Sea freight: 3–10 days
- Shipments requiring inspection: 7–21 days
Delays often occur due to:
- Incorrect paperwork
- Missing signatures
- Undeclared items
- Restricted goods
- Incorrect valuations
Working With a Customs Broker: Why It Helps
A customs broker is a licensed specialist who manages customs clearance on your behalf. They understand regulations for your destination country and ensure all documentation is filed accurately.
A customs broker can:
- Prepare customs declarations
- Handle duties and taxes
- Communicate with customs officers
- Prevent paperwork mistakes
- Ensure faster release of the shipment
Most international moves handled by companies like United Local Movers include customs brokerage assistance or partner with reliable brokers overseas.
