Customs Audit: What Importers and Exporters Need to Know

Trading on an international point of view often requires lots of documentation, as well as correctly made declarations and customs regulations observance. But what is after the customs phase or after the goods have been delivered the customs area? The customs bodies may come to the transactions, documents, declarations, and processes review in order to check the correctness of information given and the duty payment and observance of other regulations.

For importers and exporters, the audit doesn’t always mean something wrong has taken place. The customs institutions increasingly conduct audits based on the risk assessment, checking that everything is fine along with other shipments. The World Customs Organization defines the post-clearance audit as a thorough examination of records, documentation, and other data after the goods have been cleared.

So how to get ready for an audit? What documents should be checked? What can be done in order to avoid mistakes? This manual describes how businesses should ready to face customs audits.

What Is a Customs Audit?

Definition and Purpose of a Customs Audit

A customs audit is an audit performed by customs authority to check if a trader complied with the relevant customs laws. An audit can be done on the entire range of the trader’s business operations instead of one single shipment. Customs authorities can be analyzing a variety of documents based on where the audit is being performed and its purpose. Some of these documents may include the following:

• Customs declarations
• Sales and purchase documents
• Commercial invoices
• Import and export documentation
• Contracts and payment information
• HS classification
• Customs Value
• Country of origin information
• Duty calculation and taxes
• Internal customs procedures
• Electronic documentation

According to WCO, post-clearance audits make it possible for customs authorities to monitor trader compliance and implement their risk management strategies. For traders, this means that complying with a law does not stop after one declaration is accepted.

Why Customs Authorities Conduct Audits

What is the purpose of analyzing the shipment even after it has been cleared out?

One of the objectives is efficiency. Today’s customs systems have been combining border checks with auditing mechanisms performed after the clearance process. According to WCO, post-clearance audits ensure quicker release of goods while allowing customs administrations to check for compliance afterward. The audit can help authorities to identify the following:

• Misrepresentations used in the declarations
• Duty underpayments or overpayments
• Incorrect classification
• Valuation issues
• Issues related to the origin of goods
• Documentation missing
• Repeated mistakes in the procedure
• Poor procedures and controls within the company

The purpose is not merely to review documents. Customs audit can enable authorities to see how the internal processes of the company work and whether these processes yield accurate declarations.

Customs Audit vs. Customs Inspection

Usually, cargo checks are concentrated on transactions that involve goods being imported or exported. Custom audit will examine cases more broadly.

For instance, a cargo check means that representatives of customs will be inspecting the shipment or confirming the shipment against documents that accompany it. Post-clearance audit can include examining many different transactions, accounting documentation, business systems and documents supporting it. Both types of inspection take place for different reasons and the coverage may vary depending on the local customs procedures and risk factors.

What Do Customs Authorities Review?

Import and Export Declarations

The initial steps of declaration review involve the checking of information submitted to customs. In order to evaluate whether declaration data is accurate, authorities can compare it to the provided financial documents. This can include checking product descriptions, quantities, values, tariff classification or other mandatory information.

For instance, where a commercial invoice states a particular piece of information differently than the external declaration, clarifying the inconsistency may be required. Thus, companies need to bear in mind that declarations are not standalone documents. Each declaration should be backed by a paper trail allowing clarifying the origin of the reported data.

Commercial Invoices and Supporting Documents

A customs audit might include an examination of the documents that were utilized in making the declaration. Depending on the transaction and jurisdiction, these documents may be:

• Commercial invoices
• Packing list
• Purchase orders
• Sales contracts
• Bills of lading
• Air waybill
• Certificate of origin
• Payment documents
• Documents related to freight and insurance
• Customs declaration

The objective of a customs audit is to compare the information provided to customs authority with business documents. Proper document management plays an important role in customs compliance; otherwise, meeting with customs authorities and providing them with necessary documentation will become much more difficult for you.

HS Codes, Customs Valuation, and Country of Origin

The areas of customs compliance that are important include classification, valuation and origin because it makes a big difference in the application of tariff regulations. A customs audit would look at factors like whether the HS code used for the product is correct and if the customs value stated is verifiable in the transaction and if the origin mentioned is accurate.

Companies should develop efficient processes for making these decisions instead of relying on guesses or reproducing data from old shipments without checking.

Duties, Taxes, and Tariff Calculations

The customs officials may look into the question whether the correct duties as well as other applicable charges and taxes have been applied correctly. A mistake in classification, value, origin, quantity, or any other element of the declaration can have an impact on the payment amount.

The regular internal audits will allow companies find the inconsistencies before they turn into permanent issues.

Importer and exporter records

The impact of a customs audit can go beyond the papers for individual shipments and cover business records related to customs business.

For example, the recommendations of HM Revenue & Customs state that the compliance checks may include inspection of business records and electronic records as well as transaction-level data if needed.

This means that companies must have a properly organized history of customs data which describes how the customs data was created, controlled, transmitted, and changed.

Common Reasons for Customs Audit Issues

Incorrect HS Classification

HS classification can turn into a compliance issue when products are complicated, descriptions are unclear or different teams classify the same goods differently. A mistake in classification can have consequences on the duties, taxes, licensing requirement, trade measures or other customs obligations.

Firms are required to have reliable classification procedures and examine their products from time to time where classification is in doubt or carries significant commercial consequences.

Undervaluation or Incorrect Customs Valuation

Customs valuation is one of the issues that gets attention during an audit. The authorities can compare declared values with transaction documents to figure out if the declared value is backed by the transaction evidence.

Firms need to keep the relevant invoices, contracts, payment documents, freight costs and the rest of the information required by the applicable valuation rules.

Errors in Country of Origin

The country of origin refers not only to the place of shipment. The rules regulating the country of origin are based on various factors including the nature of goods, the type of manufacturing process conducted and the specifics of intergovernmental agreements. If there is an error in defining the country of origin, compliance issues may arise even if other elements of the customs declaration form are filled out correctly. An established process for determining the country of origin can help explain the choice made.

Incomplete or Inconsistent Documentation

What types of issues may arise if the information about the goods is inconsistent in different documents?

In some cases, an invoice may identify products according to a different definition than the one used in the declaration. In turn, a packing list may report a different number of items or the value of goods identified within the internal report may differ from the one indicated in the declaration. In some cases, the discrepancy may be explained, however in some cases the recurrence of inconsistencies points at flaws in the company’s customs processes.

How to Prepare for a Customs Audit

Maintain Accurate and Complete Trade Records

The best time to get ready for an audit is before obtaining an audit notice. It is important to have a systematic method for saving information about customs so that each entry can be connected to its documents.

An example of an effective information-saving system involves connecting:

Shipment → Commercial documents → Goods classification → Customs declaration → Supporting documents → Submission → Amendments → Result

This contributes to making the audit process straightforward and beneficial in case of questions regarding transactions.

Review Customs Declarations Regularly

Do not take it for granted that an accepted customs declaration guarantees that the information provided is accurate. Conduct periodic audits of certain customs declarations and check if the information corresponds to the evidence provided. Pay attention to products that are traded in high volumes, HS codes that are used often, peculiar sales, and the products or suppliers that have undergone changes recently.

For UK businesses, HMRC provides information about customs that can assist with the audit process.

Establish Document Management Procedures

Your team should be aware of:

• The documents that need to be kept
• Their storage locations
• The individuals responsible for their management
• The relationship between documents and declarations
• The recording of amendments
• The time period within which records should be kept

The requirements for record retention can differ depending on the region, so it is important for businesses to find out what applies for their activities.

Conduct Internal Customs Compliance Checks

Internal audits are much the same as a smaller version of an audit. Sample the previous transactions and examine whether:

• The declaration complies with the necessary commercial papers
• The product Code classification is confirmed
• The declared price is precise
• The country-of-origin determination is substantiated
• The required customs regulations were followed
• All necessary documents are available
• There were any amendments and if they were recorded

Internal audit can uncover weaknesses in processes before the external one.

Train Teams on Customs Requirements

Customs compliance is typically handled by multiple people. Procurement can create purchase data. Logistics can manage shipping information. Finance can deal with invoices and payments. Customs specialists can work on declarations.

If those teams work on different versions of the same data, inconsistencies can arise. Regular training and proper assignment of responsibilities can help make the customs process more coherent.

What Happens During a Customs Audit?

Audit Notification and Preparation

The exact methods may vary from one administration to another, but it might involve a request from the business concerning records, information, explanations, or access to pertinent systems. Once you have been notified, do not respond to it by collecting documents randomly. You need to firstly determine:

• What the period of audit is
• What transactions are involved
• What customs legislation is involved
• What documents are requested
• What are up the responsible internal departments
• What external customs service provider or broker takes part in it

Structured response will definitely help in handling it rather than in hurry across many systems

Document Requests and Data Review

The authorities may want to check not only documents but also electronic records. Besides nowadays the audit may involve information obtained from the business systems but not only paper documents. For example, guidance of HMRC describes the utilization of electronic processes in auditing. Thus, a company needs to ensure that its electronic records are sufficiently accessible, coherent and verifiable so that it can be traced back to original transaction.

Communication With Customs Authorities

In case you are unable to understand a request, ask for further details. If a document is not available you must provide an explanation instead of merely stating that you do not have information. It is also important to keep all records of communication, any documents provided, and any clarifications given. A well-maintained audit trail would enhance the overall auditing process.

Identifying and Addressing Discrepancies

The next step would depend on the jurisdiction, the nature of the discrepancies, as well as the respective legislation involved. Accordingly, businesses should carefully examine the findings and seek important advice. The most crucial thing is to know what caused that mistake.

Audit Findings and Follow-Up Actions

An audit's conclusion can lead to findings, requests for action to correct the situation, and further evaluation depending on the legal framework and circumstances. Companies must regard the results as a chance to enhance their customs operations. Considerations include:

• What is the reason for this situation?
• What number of transactions is potentially affected?
• Whose team is accountable for the whole process?
• What measures can be applied to prevent the situation from happening again?
• Are past declarations to be checked?
• Is it necessary to change the existing procedure?

How Technology Can Simplify Customs Audit Preparation

Centralizing Trade and Customs Documents

Audits become complicated when customs documentation is spread around in emails, spreadsheets, folders, and multiple systems. With a centralized digital process, companies can link up their customs documents and declarations. This is especially important for companies that send and receive many shipments since finding required documents manually can take much time.

Using Automation for Data Collection and Verification

Artificial Intelligence and automation help to avoid unnecessary data entry by extracting information from customs documents and verifying it before sending it out.

For example, Droblet explains how one of their processes works: first, companies upload customs documents, then the necessary information is collected, compliance is checked, and customs declarations are made.

Detecting Errors Before Submission

The greatest advantage of compliance detection needs to be its ability to identify problems before a declaration is filed with customs authorities. Automated validation technology is capable of detecting incorrect or missing data before the submission is made.

For example, Droblet’s ICS2 workflow includes capabilities for automatic data extraction, validation, error marking, submission, and tracking. However, it still needs human oversight of the process. This technology enables compliance professionals to use their skills on more complicated cases that require some decisions.

Creating an Audit-Ready Record Trail

It is also possible to use technology for audit readiness support and to preserve documents, declarations, and updates associated with the declaration.

For instance, Droblet’s ENS platform describes real-time declaration tracking and keeping changes history in order to conduct necessary audits. Retention rules applicable will depend on the regions where the company operates, while the basic idea is that customs data should be kept at all times.

How to Reduce Future Customs Audit Risks

Build a Strong Customs Compliance Process

A successful compliance procedure should clarify who is in charge of classification, valuation, country of origin determination, preparation of documentation, making declarations, reviewing and record keeping. Also, potential consequences in case of an error must be specified.

This way, as responsibilities are stated clearly, reliance on a single person to follow each step will decrease.

Keep Track of Changes in Regulations and Tariffs

Customs regulations do change but companies operating in different countries have to keep track of several customs regulations at once. Any amendments in tariffs, documentation requirements, declaration systems, agreements on trade, and import requirements will have an impact on existing procedures.

Think about including customs regulations tracking into the usual compliance procedures instead of treating it as an event of rare occurrence.

Conclusion

When a business receives a request for documents, declarations, or transaction records over several years, customs audit seems scary. However, the process of preparation should not start once the notification of audit is received. Preparation starts right at each shipment.

Proper declarations, careful documentation of decisions over classification, valuation, and customs procedures, and designated responsibilities contribute to increased compliance. WCO’s view of post-clearance audit emphasizes the importance of having a risk-based approach and using audits to monitor and improve compliance level.

For importers and exporters, an important question is not simply `Are we ready for customs audit?`

Another question to think about would be `Can we substantiate and justify every crucial customs-related decision?`

If the answer is positive, then the company is in much better position to cope with customs audits.
