The Most Important Reasons for Cargo Held at Customs

Cargo being held at customs is one of the challenges that can disrupt import and export operations and create additional costs for cargo owners. When a shipment is held at customs, its clearance may be delayed due to incomplete documentation, discrepancies in shipment information, valuation issues, missing permits, or the need for further inspection.

Cargo being held at customs does not always mean that a shipment has violated regulations or contains prohibited goods. Sometimes, a simple error in shipping documents or a customs declaration can prevent the cargo from being released until the information is corrected or additional documents are provided. In other cases, customs authorities may conduct documentary or physical inspections to ensure compliance with applicable laws and regulations.

Understanding the most important reasons for cargo being held at customs helps importers, exporters, and trading companies review their documents and clearance requirements before shipping. This article explains the main causes of customs holds, their consequences, and practical ways to reduce the risk of delays.

What Does It Mean When Cargo Is Held at Customs?

Cargo held at customs refers to a situation in which a shipment cannot proceed or be released from customs while the required checks, procedures, or corrective actions remain incomplete.

This situation may be temporary and resolved by submitting additional documents, correcting a customs declaration, paying applicable duties and taxes, or obtaining the required permits. However, if the goods are legally prohibited or a serious violation is identified, the case may require a longer review or lead to further legal action.

For example, if the value stated on a commercial invoice does not match the information declared to customs, the customs officer may request additional supporting documents. Similarly, if goods require a health certificate, conformity approval, or import permit and the required document has not been provided, customs clearance may be suspended until the matter is resolved.

Therefore, the first step in addressing a customs hold is to identify its exact cause. Without understanding the underlying issue, actions such as resubmitting documents or paying additional charges may not solve the problem.

What Are the Main Reasons for Cargo Held at Customs?

Several issues can cause cargo to be held at customs. Some relate to documentation and shipment information, while others involve import and export regulations, customs valuation, inspections, or transportation conditions.

1. Incomplete or Inconsistent Customs Documents

One of the most common reasons for cargo being held at customs is missing documentation or inconsistencies between different shipping and commercial documents.

During international import and export operations, the information on the commercial invoice, packing list, bill of lading, and customs declaration should be consistent. Any discrepancy in the quantity, weight, product description, seller or buyer details, or other important information may lead to additional questions or further examination.

Common documentation problems include:

An incomplete commercial invoice or packing list
Differences between the declared number of packages or shipment weight and the shipping documents
Incorrect details about the cargo owner
An unclear or inaccurate description of the goods
A missing certificate of origin when required
Conflicting information in the customs declaration and transport documents

To reduce the risk of delays, all documents should be reviewed before the shipment is dispatched, and their information should match the actual characteristics of the goods.

2. Errors in the Customs Declaration

The customs declaration is one of the main documents used during the customs clearance process. The information it contains forms the basis for examining the goods, calculating duties and taxes, and completing customs procedures.

If the declaration contains incorrect information or does not match the commercial documents and the actual shipment, customs clearance may be delayed.

For example, an incorrect product description, weight, quantity, country of origin, or tariff classification may cause the shipment to be referred for further review. In more serious cases, discrepancies may trigger additional legal procedures under the applicable regulations.

For this reason, customs declarations should be prepared using accurate information and valid supporting documents. All details should also be checked before the declaration is submitted.

3. Disputes Over Customs Valuation

Customs valuation plays an important role in calculating import duties and certain other charges. If customs authorities question the declared value of a shipment, they may request additional documents to verify the actual transaction value.

For example, if the declared value does not appear consistent with the available information about the goods or the supporting purchase documents, further examination may be required. Customs authorities may also review the commercial invoice, transaction terms, and transportation and insurance costs when determining the customs value.

In these situations, providing a valid invoice, payment records, purchase contract, and relevant freight cost documents can help clarify the matter.

It is important to note that customs value is not necessarily identical to the amount shown on the commercial invoice. Its calculation depends on the customs valuation rules applicable in the destination country.

For more information, consult the World Customs Organization’s guide to customs valuation.

4. Incorrect Customs Tariff Classification

Goods are classified under specific tariff codes according to their characteristics, composition, function, and technical specifications. This classification can affect import duties, trade restrictions, and the permits required for clearance.

If the selected tariff code does not correspond to the actual nature of the goods, customs authorities may request additional information to review the classification.

This issue is particularly important for industrial equipment, machinery parts, chemicals, and products that have multiple potential applications.

To reduce the risk of a customs hold, the product’s technical description, catalogue, manufacturer specifications, and other relevant information should be prepared in advance. Tariff classification should be based on the actual characteristics of the goods and the applicable regulations.

5. Missing Legally Required Permits

Certain goods require specific permits or certificates for import or export. These requirements may depend on the type of product, the country of origin or destination, and the regulations in force.

For example, some goods may require health permits, conformity certificates, quarantine approvals, environmental permits, or other specialized authorizations. If a required permit is missing or invalid, customs clearance may be delayed or suspended.

Requirements that should be checked before shipment include:

Import or export permits, where applicable
Health and quarantine certificates for regulated goods
Conformity or standards certificates where legally required
Permits related to chemicals or other controlled products
Documents relating to applicable trade restrictions

Permit requirements are not the same for every product. Therefore, it is important to check the regulations governing the goods and the destination country before purchasing or dispatching a shipment.

6. Legal Restrictions or Prohibitions on Imports and Exports

In some cases, cargo held at customs not because of missing documents, but because the goods are subject to legal restrictions or prohibitions.

Certain products may be completely prohibited, while others can only be imported or exported under specific conditions and with the required permits. These restrictions may depend on the type of goods, their intended use, the country of origin, the destination country, or applicable trade regulations.

If an importer fails to verify the legal status of a product before placing an order and shipping it, the shipment may encounter serious clearance problems after arrival.

For this reason, confirming whether goods can legally be imported or exported should be part of the process before a transaction is finalized. Previous experience or the successful clearance of a similar product is not enough, because regulations may change or the circumstances of the new shipment may be different.

7. Discrepancies in the Country of Origin or Certificate of Origin

The country of origin can affect applicable tariffs, trade restrictions, and regulatory requirements. If origin information is inconsistent across documents or a required certificate is missing, customs authorities may conduct additional checks.

It is also important to distinguish between the country where goods originate and the country from which they are shipped. Transporting goods through a country or dispatching them from a particular port does not necessarily mean that the goods were produced there.

If a certificate of origin or other origin-related document is required, its information must be accurate and verifiable.

For further information, consult the World Customs Organization’s guidance on rules of origin.

8. Differences in Shipment Weight, Quantity, or Physical Characteristics

Another reason for cargo being held at customs is a discrepancy between the information in the shipping documents and the actual shipment.

For example, the number of packages shown on the packing list may differ from the actual quantity, or the shipment weight may not match the bill of lading or customs declaration. A physical inspection may also reveal that the goods differ from the description provided in the documents.

In these circumstances, customs authorities may hold the shipment for counting, weighing, or more detailed examination.

To prevent such issues, packaging and loading information should be recorded accurately. If shipment details change, the relevant documents should be updated in accordance with the applicable procedures.

9. Physical Inspection or Additional Customs Examination

Not every customs hold indicates an error or violation. Sometimes, shipments are selected for documentary review, physical inspection, or risk-based examination.

During a physical inspection, customs authorities may examine the contents of packages, the quantity of goods, product specifications, shipment weight, or whether the cargo matches the customs declaration. In some cases, inspection equipment or other control methods may be used to verify compliance.

The duration of these checks depends on the type of goods, shipment volume, customs procedures, and whether additional information is needed.

The European Commission’s guidance on customs controls explains that customs checks can include documentary controls and physical inspections. However, the specific rules and procedures differ from one country to another.

10. Unpaid Customs Duties and Taxes

In many cases, goods can only be released after the required customs procedures have been completed and applicable charges have been paid. If import duties, taxes, or other legally required amounts remain unpaid, the release of the shipment may be delayed until the outstanding issues are resolved.

Sometimes, disagreements over calculations or uncertainty about the final amount can also delay clearance because the cargo owner needs additional time to determine the correct payment.

To reduce the risk of a customs hold for this reason, importers should estimate potential import costs before dispatch and ensure that sufficient funds are available to cover the required payments.

11. Problems With Bills of Lading and Shipping Documents

A bill of lading is an important international transport document. Depending on the type of transport document, it may contain information about the shipper, consignee, goods, and transportation arrangements.

Errors in the bill of lading, inconsistencies with the commercial invoice or customs declaration, or missing documents required for cargo release can complicate the clearance process.

For example, if the consignee’s details in the transport documents do not match the cargo owner’s information or the customs records, the relevant documents may need to be corrected or additional explanations provided.

Coordination between the shipper, transport company, cargo owner, and customs broker before dispatch can help prevent many of these problems.

12. Transportation and Cargo Storage Requirements

Some shipments require special transportation and storage conditions. Temperature-sensitive goods, perishable products, and hazardous materials, for example, may require specialized equipment, documents, or permits.

If the transportation arrangements do not meet the legal requirements or the specific needs of the goods, further examination may be necessary. In some cases, the clearance process cannot continue until the required conditions are met.

Customs delays can also create additional risks for goods with limited shelf lives or products that must be stored under controlled conditions.

For this reason, the appropriate transportation method, specialized documentation, and cargo storage arrangements should be planned before the shipment begins.

What Are the Consequences of Cargo Being Held at Customs?

A customs hold does not only delay delivery. It can also create several direct and indirect costs for the cargo owner.

Increased Warehousing Costs

The longer a shipment remains at a customs facility, the greater the potential storage and handling costs. These charges depend on the type of goods, the storage location, applicable tariffs, and the duration of the hold.

Higher Transportation Costs

A customs delay may disrupt domestic or international transportation schedules. As a result, additional expenses may arise from rescheduling vehicles, rearranging transport bookings, or moving the shipment.

Disruptions to Production and Sales

If the cargo consists of factory raw materials or products required by a retailer, a clearance delay can affect production schedules, inventory availability, and order fulfilment.

Increased Risk of Cargo Damage

Some goods may deteriorate or lose quality if they remain in storage for too long or are kept under unsuitable conditions. This is particularly important for perishable products and temperature-sensitive goods.

Financial Pressure on Businesses

Capital tied up in a shipment that cannot be released is unavailable for other business activities until the matter is resolved. This can affect cash flow, purchasing plans, and financial management.

How Can You Prevent Cargo From Being Held at Customs?

Although not every customs inspection or hold can be prevented, several practical measures can reduce the risk of avoidable problems.

1. Review All Documents Before Dispatch

The commercial invoice, packing list, bill of lading, certificate of origin, and other required documents should be reviewed before the shipment leaves. The information in all documents should be consistent with the actual goods.

2. Check Tariff Classification and Applicable Regulations

Before purchasing or shipping a product, verify its customs tariff classification and any import or export restrictions. This helps identify permit requirements and estimate potential charges more accurately.

3. Obtain the Required Permits and Certificates

If the goods require a specific permit or certificate, the application process should ideally begin before the shipment arrives at customs. The validity and conditions of use of each document should also be checked.

4. Choose an Experienced Transport Company and Customs Broker

Proper coordination between transportation, commercial documentation, and customs procedures plays an important role in reducing errors. Working with a company experienced in international cargo operations can help identify potential problems before dispatch.

5. Estimate Clearance Costs Before Shipping

Import duties, taxes, customs service charges, warehousing costs, and other potential expenses should be assessed before dispatch. This reduces the likelihood of delays caused by insufficient funds.

6. Verify Packaging and Loading Information

The weight, number of packages, type of goods, and information shown on packaging should match the shipping documents. Accurate records can help prevent discrepancies during customs inspection.

7. Monitor the Shipment Regularly

Once the goods have been dispatched, their transportation and customs status should be monitored regularly. If customs authorities or the customs broker request additional documents, responding quickly and accurately can help prevent unnecessary delays.

What Should You Do if Your Cargo Is Held at Customs?

If a shipment is held at customs, the first step is to identify the exact reason. Without understanding the cause, it can be difficult to determine whether documents need to be corrected, permits must be provided, or other action is required.

Follow these steps to manage the situation effectively:

Identify the reason for the hold: Ask the customs broker or relevant authority to clarify why the shipment is being held and what actions are required.
Review the documents: Compare the commercial invoice, bill of lading, packing list, customs declaration, and other relevant records.
Complete or correct the documentation: If missing information or discrepancies are identified, make the necessary corrections through the appropriate legal procedures.
Resolve permit and payment issues: Where required, provide the necessary permits or settle applicable charges.
Keep records of all communications: Retain requests, responses, and submitted documents so that the progress of the case can be tracked.
Consider legal options if a dispute arises: If there is a disagreement about customs valuation, tariff classification, or a customs decision, seek advice from a qualified specialist and consider the available formal appeal procedures.

The time required to resolve a customs hold depends on the reason, the type of goods, the regulations in the relevant country, and how quickly the necessary information is provided. There is no single timeframe that applies to every shipment.

The Role of a Freight Forwarder in Reducing Customs Delays

An international freight forwarding company can help coordinate communication between the shipper, consignee, customs broker, and other parties involved in the shipment.

This support may include preliminary checks of shipment information, coordination of transport documents, route selection, communication about operational requirements, and monitoring of the shipment’s progress.

However, responsibility for preparing certain documents or obtaining permits may vary depending on the contract, the laws of the destination country, and the role of each party. Responsibilities should therefore be clearly defined before transportation begins.

In international shipping, early coordination between purchasing, cargo preparation, documentation, transportation, and customs clearance can prevent many avoidable costs and delays.
