Key Takeaways

• Paperless refers to an electronic customs clearance system that enables import–export information and customs declarations to be submitted through electronic systems.
• Business operators who need to carry out customs procedures must register with the Thai Customs Department first.
• The main registration channels currently include Customs Department registration service units, the Customs Trader Portal, and Online Customs Registration.
• Paperless registration does not mean that business operators must prepare customs declarations themselves. They may appoint a customs broker or customs clearance agent.
• Registration and status checks should be completed before a commercial shipment to help prevent goods from arriving in Thailand before customs procedures can be carried out as planned.

Before starting commercial imports or exports, business operators often encounter the terms “Paperless registration” or “opening a Paperless account with Customs.”

These terms are directly related to customs clearance because import–export procedures today involve submitting information through electronic systems, including customs declaration data, duty payments, and information related to customs clearance.

Therefore, if a company or individual is preparing to begin importing or exporting for business purposes, one of the things to prepare before the first shipment is to check whether they have completed registration to carry out customs procedures or participate in the relevant customs processes.

What Is Customs Paperless?

In the customs context, the term Paperless describes carrying out customs procedures through electronic systems rather than relying primarily on traditional paper documents.

This system helps import–export information be linked and submitted to the Thai Customs Department as Electronic Data.

Examples of related processes include:

• Preparing import customs declarations
• Preparing export customs declarations
• Submitting cargo information
• Paying duties electronically
• Linking Manifest data
• Checking Customs status
• Linking permits or information from relevant agencies in certain cases

In current government systems, the terminology is associated with registration of persons conducting customs procedures or participating in customs processes.

However, many people in the Logistics industry still refer to it simply as:

“Paperless registration”

Who Should Register for Paperless?

Business operators who need to carry out import–export procedures with the Thai Customs Department should check their registration status. These may include:

• Companies importing goods for resale
• Companies importing raw materials
• Factories importing machinery or parts
• Business operators exporting goods overseas
• SMEs starting Import–Export operations
• Individuals with commercial shipments, subject to the applicable conditions
• Importers
• Exporters

Do not wait until goods arrive in Thailand to check whether Registration is ready. Doing so may affect Customs Clearance and lead to costs associated with delays.

What Can You Do After Registering for Paperless?

Once registration with the Thai Customs Department has been completed in accordance with the required procedures, business operators can carry out customs-related activities relevant to their businesses.

Examples include:

• Importing goods
• Exporting goods
• Preparing Customs Declarations
• Appointing a customs clearance agent
• Linking data required for customs procedures
• Handling duties and taxes
• Using relevant customs services according to registration privileges and type

Registration is therefore part of the back-end Infrastructure for an Import–Export business.

Are Paperless and e-Customs the Same?

The terms are related, but their contexts should be understood clearly.

Paperless is a commonly used term referring to customs procedures that reduce the use of paper documents and rely on Electronic Data.

e-Customs refers more broadly to electronic customs systems and processes.

Therefore, when a Freight Forwarder or Shipping Agent asks:

“Has your company registered for Paperless?”

They are generally checking whether the business has Registration in place to carry out the Customs Process.

Is Paperless Registration the Same as Registering an Import–Export Company?

No.

Registering a company with the Department of Business Development and registering with the Thai Customs Department are separate procedures.

For example:

ABC Co., Ltd. may have completed company registration and included trading activities in its business objectives.

This does not automatically mean that the company is registered to carry out customs procedures.

If it intends to import or export goods, it must separately check its Registration with the Thai Customs Department.

The steps should therefore be distinguished as follows:

Company Registration → Customs Registration → Import / Export Process

How Many Channels Are Available for Importer–Exporter Registration?

The Thai Customs Department provides three main channels for importer–exporter registration.

1. Register at a Thai Customs Department Registration Service Unit

Business operators can submit an application at a designated registration service unit of the Thai Customs Department.

This option may be suitable when:

• They want to submit documents directly to an officer
• Their business type is not supported by certain Online channels
• They prefer to process the application directly through a service unit

For registration at a service unit, the authorized signatory must prepare documents and evidence required for the applicant type, including identity verification documents specified by the Thai Customs Department.

Before visiting, check the latest Checklist because requirements may differ for:

• Individuals
• Juristic persons
• Authorized representatives

2. Register Through the Customs Trader Portal

Another channel is the Customs Trader Portal.

This system allows business operators in supported categories to complete Registration online.

Importer–exporter groups supported under the current conditions include:

• Thai nationals applying as individuals
• Juristic persons whose directors are all Thai nationals

The system requires identity verification through the channels it specifies, such as an application used for Identity Verification.

For juristic persons, check that the company name in both Thai and English matches the registered information before proceeding.

3. Register Through Online Customs Registration

Business operators can also use Online Customs Registration on the Thai Customs Department's system.

This channel supports identity verification and Electronic Signatures in accordance with the specified procedures.

The process may involve:

• Digital Certificate
• Electronic Signature
• ThaID for certain eligible users

The applicable method depends on the business type and the authorized persons of the juristic entity.

Check the Eligibility requirements for each channel before starting registration.

What Is a Digital Certificate?

A Digital Certificate is an electronic certificate used to help verify identity and support Electronic Signatures in electronic systems.

For some customs registration channels, business operators may need a Digital Certificate issued by a supported Certificate Authority.

Its main function is to help verify that Electronic Data has been submitted by an authorized person or someone appointed under the system.

However, alternative identity verification channels are now available in some cases. Therefore, it should not be assumed that every business operator must purchase a Digital Certificate first.

Choose a registration channel and then check its specific Requirements.

Can ThaID Be Used for Customs Registration?

Online Customs Registration supports identity verification through ThaID for certain applicant types, subject to the conditions specified by the system.

Eligible groups may include:

• Thai nationals applying as individuals
• Juristic persons whose director structure meets the specified conditions

Companies with multiple directors or foreign directors should not assume that they can use the same Flow.

Check which channel is appropriate for the company's structure before registering.

What Should You Prepare Before Registering for Paperless?

The required documents depend on:

• Whether the applicant is an individual or a juristic person
• The selected channel
• The authorized person
• Whether authorization has been granted to another person
• The identity verification method

However, the following information should be prepared in advance:

• Individual or company information
• Tax Identification Number
• Information about the authorized signatory
• Company name in Thai and English
• Company address
• Email
• Telephone number
• Account information or other information required by the system, where applicable
• Power of Attorney, if someone will act on the applicant's behalf
• Identity verification documents required by the selected channel
• Digital Certificate, if required by that channel

Because Requirements may change, download the latest application forms and Checklist from the Thai Customs Department's system before submitting an application.

Steps for Importer–Exporter Paperless Registration

The overall process can be divided into five steps.

Step 1: Check Whether the Company Is Already Registered

Before applying for new registration, check the existing Registration first.

This is especially important for companies that:

• Have been operating for a long time
• Have handled shipments in the past
• Have changed Logistics staff
• Have changed Freight Forwarders
• Have not imported or exported for some time

The company's information may already exist in the system.

Applying again without checking the existing information may waste time and lead to data correction work later.

Step 2: Choose a Registration Channel

Choose one of the following:

• Thai Customs Department service unit
• Customs Trader Portal
• Online Customs Registration

Base the choice on the business type and the company's authorized-person structure.

Do not choose solely for convenience, because each channel may have different Eligibility requirements.

Step 3: Prepare Information and Verify Identity

Check the following:

• Juristic person's name
• Registration number
• Tax ID
• Authorized person
• Email
• Telephone number
• Supporting documents
• Digital Identity

Make sure all information is correct.

Company information should match the records held by the relevant government agencies, especially the juristic person's English name.

Step 4: Complete the Required Steps Until Registration Is Finalized

For an Online System, complete the following as applicable:

• Enter the required information
• Verify identity
• Complete the Electronic Signature process, where applicable
• Review the information
• Submit the application

Continue until the system displays the Registration status required by the process.

For applications submitted at a service unit, follow the officer's document-verification procedures.

Step 5: Check the Status Before Shipping

After registration, check the status again before the first shipment.

This is especially important when:

• Registration has just been completed
• The system has not been used for a long time
• Company information has changed
• The authorized person has changed
• The customs clearance agent has changed

This helps ensure that the Shipping Agent can submit the Customs Declaration according to plan.

Does Registration Need to Be Completed Only Once and Then Last Forever?

Do not assume that registration never needs to be checked again after completion.

Registration information may need to be updated when changes occur, such as:

• Company name
• Address
• Directors
• Authorized persons
• Customs clearance agent
• Accounts or information linked to the system
• Contact information

In addition, if no customs procedures are carried out for a period specified under the applicable rules, the system status may need to be checked or the registration information may need to be reactivated.

Companies resuming import–export activities after a long pause should therefore ask their Shipping Agent to check Registration before the goods leave the country of origin.

After Registering for Paperless, Must You Prepare Customs Declarations Yourself?

No.

Business operators can appoint a customs broker or customs clearance agent to carry out customs procedures on their behalf, in accordance with the relevant process.

Example Flow:

Importer → Sends documents to Customs Broker → Broker prepares the declaration → Importer checks the information → Data is submitted to Customs → Customs Clearance

Paperless Registration therefore helps ensure that the company is registered and ready for the Customs Process.

It does not mean that every business must employ staff to enter customs declarations themselves.

What Does a Customs Broker or Customs Clearance Agent Do?

A customs clearance agent helps carry out customs-related tasks, such as:

• Reviewing Shipping Documents
• Checking declaration data
• Preparing Customs Declarations
• Coordinating the Customs Process
• Checking relevant Permits
• Coordinating cargo inspections
• Coordinating Duty & Tax matters
• Carrying out tasks within the agreed Service Scope

However, the Importer or Exporter must still provide accurate information about its goods.

A customs clearance agent cannot determine product information on behalf of the business operator without sufficient Product Information.

Does Paperless Registration Allow You to Import Any Type of Product?

No.

Customs Registration is only one part of the Import–Export process.

Different product categories may still require:

• Thai FDA approval
• TIS certification
• Import licenses
• Export licenses
• Licenses from specific agencies
• Certificates
• Product Registration

For example, a company may have completed Paperless Registration but still need to check the requirements of the Thai Food and Drug Administration before importing food.

After Registering for Paperless, Do You Still Need to Check the HS Code?

Yes.

The HS Code remains important for Customs Declarations.

It affects:

• Import Duty
• FTA eligibility
• Product Regulation
• Permits
• Trade Measures
• Customs Classification

Registration establishes the business operator's status.

The HS Code identifies the goods.

These are separate matters.

How Is Paperless Related to Customs Declarations?

For an actual shipment, the Importer or Exporter must have a Customs Declaration appropriate to the type of transaction.

Declaration data may include:

• Importer / Exporter
• Consignee
• Product Description
• HS Code
• Quantity
• Customs Value
• Country of Origin
• Transport Information
• Duty & Tax
• Permit
• FTA Information

This information is submitted electronically through the Customs system.

The business operator's Registration must therefore be ready before declaration data is submitted.

How Is Paperless Related to Tax Payments?

Importing goods may involve:

• Import Duty
• VAT
• Excise Tax, depending on the product
• Other duties or taxes required by law

Tax information is linked to the Customs Declaration, and payments can be processed electronically in accordance with customs procedures.

However, Paperless Registration does not reduce taxes.

The amount payable depends on:

• Customs Value
• HS Code
• Duty Rate
• FTA
• Country of Origin
• Product Type

How Is a Certificate of Origin Used with Paperless?

If an Importer wants to claim preferential tariff treatment under an FTA, a Certificate of Origin or other Proof of Origin may need to be submitted as supporting documentation for the Customs Declaration.

Examples include:

• Form D
• Form E
• Proof of Origin under other FTAs

Paperless Registration helps the Importer become ready to carry out the Customs Process, but the relevant Origin Documents must still be prepared separately for each shipment.

Should Paperless Registration Be Completed Before Goods Leave the Country of Origin?

For a commercial shipment, registration should be completed before the goods leave the country of origin, especially if it is the company's first shipment.

If the goods arrive while Registration issues remain unresolved, this may affect:

• Customs Clearance
• Storage
• Demurrage / Detention, where applicable
• Warehouse Charges
• Delivery Schedule
• Production Plan

A safer sequence is therefore:

Check the goods → Check permits → Complete Customs Registration → Check Shipping Documents → Booking → Shipment

Do not ship the goods first and assume that registration can be completed in time for their arrival.

When Should First-Time Importers Register for Paperless?

If a business plans to import a Commercial Lot, it should start checking the requirements when:

• A Supplier has been selected
• The goods and HS Code are being reviewed
• The first shipment is about to be Confirmed

There is no need to wait until the Container or Air Cargo is Ready.

The best time is during Import Process preparation, while there is still time to correct company information or documents if an issue is found.

Is Paperless Registration Different for Individuals and Companies?

Yes, the details differ.

The Thai Customs Department offers Registration for different types of business operators, but the following may vary:

• Identity Verification method
• Documents
• Authorized Person
• Supported Online registration channels

Individuals should not use a juristic person's Checklist, and companies should not directly follow the procedures for individuals.

Can a Company with Foreign Directors Register?

Having foreign directors does not automatically mean that a company cannot register with the Thai Customs Department.

However, some Online channels have restrictions based on nationality or the company's director structure.

For example, the Customs Trader Portal has eligibility conditions for importer–exporter registration.

If a company does not meet those conditions, it should choose another channel specified by the Thai Customs Department, such as a supported form of Online Customs Registration, or apply through a service unit.

Check Eligibility before starting the Process.

If We Change Freight Forwarders, Do We Need to Register for Paperless Again?

In general, changing Freight Forwarders does not mean that the company must register as an Importer or Exporter from scratch.

However, if the company:

• Changes its customs clearance agent
• Adds a customs clearance agent
• Removes a customs clearance agent

It may need to update agent information or authorization in the system according to the relevant procedures.

Before the shipment, the company should check with the new Forwarder to ensure that the agent information and Registration are ready for use.

Why Does a Shipping Agent Ask for Company Documents?

When handling customs procedures, a Shipping Agent must verify that the business operator and the person granting authorization have accurate information relevant to the shipment.

Information that may be required includes:

• Importer / Exporter name
• Tax ID
• Address
• Authorized Person
• Registration Status
• Power of Attorney, where applicable

Shipment documents may also be required, such as:

• Commercial Invoice
• Packing List
• Bill of Lading / Air Waybill
• Permit
• Certificate of Origin

Therefore, do not submit only a Product Invoice and assume that Customs Clearance can proceed immediately.

Does Paperless Eliminate All Paper Documents?

The term Paperless does not mean that Import–Export transactions no longer require any documents.

Business operators still need documentation to support their transactions, such as:

• Commercial Invoice
• Packing List
• Transport Document
• Certificate
• Permit
• Purchase Document
• Product Specification

However, more data submission and process steps can be carried out electronically.

Original documents may still be required under the law or according to the requirements of specific agencies.

Benefits of the Paperless System for Import–Export Businesses

Electronic customs procedures support several aspects of operations.

1. Reduce Traditional Document Submission Steps

More information can be submitted through electronic systems.

2. Reduce Coordination Time

There is less need to physically submit paper documents at every stage, as was common under traditional systems.

3. Improve Data Connectivity

Importer information, Declarations, and related processes can be handled within one system or through interconnected systems.

4. Support Electronic Signatures

This helps verify identity and data submissions in accordance with the specified Process.

5. Provide a Clearer Structure for Customs Clearance

When Registration and information are correct, shipments can move through a more systematic Workflow.

However, efficiency still depends on the accuracy of Product Data and Shipping Documents.

Common Problems Before the First Shipment

Examples of issues that should be checked early include:

• The company has never registered with Customs
• Existing Registration is no longer usable
• Company information has changed but has not been Updated
• The company's English name does not match
• The authorized person has changed
• A customs clearance agent has not yet been added
• The Supplier has shipped the goods but the Permit is not ready
• The Invoice does not match the company name
• The HS Code has not been checked
• The Importer does not know that the goods require a license
• The Shipping Agent receives documents too late

Most of these problems can be prevented through a Pre-Shipment Check.

Checklist for Companies Making Their First Import

Before the Supplier ships the goods, check the following:

• Has the company registered with Customs?
• Is the Registration Status ready?
• Has a customs clearance agent been appointed?
• Is the Power of Attorney ready?
• Is the Product Description clear?
• Has the HS Code been checked?
• Is an Import Permit required?
• Is the Commercial Invoice correct?
• Is the Packing List ready?
• Is the Country of Origin correct?
• Can an FTA be used?
• Has the Freight Booking been Confirmed?
• What are the Incoterms?
• Have Duty & Tax been estimated?
• Has Destination Delivery been planned?

If any item on the Checklist is not ready, it should be resolved before Cargo Departure to help reduce costs caused by delays.
