Customs, Origin & Trade Compliance

Correct tariffing, origin documentation, and customs processes are not just paperwork, they are the foundation of smooth international trade. We handle the practical work, from HS codes to EUR.1.

Customs and origin is not just paperwork. It is often the difference between a smooth shipment and a delay that costs.

At Slinkert & Aarøe, we help companies with the practical aspects of import, export, tariffing, origin, and customs documentation. We work with HS codes, BTI applications, EUR.1, A.TR., supplier declarations, CBAM, and export control.

We can help with one-off tasks and with establishing a fixed process, so the company knows what to document, who delivers what, and how to handle it correctly going forward.

What we help with

Tariffing, HS codes & BTI

Correct tariffing is one of the most important starting points in international trade. The right commodity code determines duty rate, documentation requirements, preferential origin, export control, and CBAM obligations.

We help companies review their products and identify the correct code, especially relevant for technical products, machinery, components, and composite goods where classification is not straightforward.

We always recommend a BTI (Binding Tariff Information) when the commodity code carries significant economic or customs relevance. A BTI gives the company a definitive ruling and serves as key documentation with authorities, customers, and freight forwarders.

We can help with

Tariffing and review of HS codes

Assessment of duty rates and documentation requirements

Clarification for import and export

Basis for BTI applications

Technical product descriptions

Collection of product data

Dialogue with customs authorities

Follow-up on BTI cases

Origin & preference documentation

When a customer requests EUR.1, A.TR., or other origin documentation, the work starts long before the certificate itself. We help assess, collect, and structure the underlying documentation.

This may include origin assessments, bills of materials, supplier declarations, commodity codes, production information, and supplier documentation. We build the foundation that must be in place before documentation is passed on to the freight forwarder, customer, or authority.

We can help with

EUR.1 and EUR-MED

Supplier declarations and invoice declarations

A.TR.

Origin assessments

Calculation of preferential origin

Review of bills of materials and commodity codes

Documentation packages for freight forwarder and authority

Preparation of basis before certificate issuance

EUR.1, A.TR. & legalisation

Many companies find that customers or freight forwarders request specific documents without it being clear what groundwork must be in place first.

At Slinkert & Aarøe, we help with the work leading up to issuance and legalisation of relevant customs and origin documents, from clarifying requirements to preparing supporting documents and dialogue with authorities.

We can help with

Preparation of basis for EUR.1

Clarification of documentation requirements

Preparation of basis for EUR-MED

Preparation of basis for A.TR.

Documentation for freight forwarder

Dialogue with customer, supplier, and freight forwarder

Preparation of supporting documents

Practical assistance through to legalisation

CBAM

CBAM has made importing more administrative for many companies, particularly where supplier data is incomplete, or where responsibility between procurement, finance, warehouse, and freight forwarder is not clearly defined.

We help companies gain an overview of which goods are covered, which information is missing, and how reporting can be handled in practice.

We can help with

CBAM reporting

Review of covered

goods

Collection of supplier data

Validation of existing reporting

Establishing a fixed CBAM process

Follow-up with suppliers

Clarification of internal responsibilities

Export control & Dual Use

A growing number of companies find that their products or components require closer assessment in relation to export control and Dual Use, particularly technical products, machinery, and electronics where the commodity code or intended use raises questions.

We help structure the assessment and documentation so the company has a stronger basis for export.

We can help with

Dual Use assessments

Review of product and goods information

Documentation for export declarations

Clarification of responsibility across the supply chain

Internal export control procedures

Clarification of documentation requirements

Customs authorisations & registrations

For some companies it makes sense to work more structured with customs authorisations and registrations. This can simplify export, reduce friction, and create a more professional process with customers and authorities.

We can help with

Approved Exporter status

Application materials and process descriptions

REX registration

Relevant customs authorisations

Dialogue with authorities

Follow-up on existing authorisations

New markets
& international trade

When a company begins selling to new countries, questions arise about customs, documentation, origin, export requirements, and practical handling. It can be difficult to get a clear picture when the freight forwarder, customer, supplier, and authorities all give different answers.

We help clarify what needs to be in place before goods are shipped.

We can help with

Import and export requirements for new markets

Documentation and origin requirements

Customs assessments

Incoterms and allocation of responsibility

Coordination between customer, supplier, and freight forwarder

Practical processes for new trade flows

Review of existing
customs setup

Many errors occur not because a company doesn't want to do things correctly, but because the processes are unclear. Who owns the commodity codes? Who collects supplier declarations? Who follows up on CBAM data?

We help companies review their current setup and identify areas where there is a risk of errors, delays, or unnecessary costs.

We review, among other things:

Commodity codes and tariffing

Origin documentation

Supplier declarations

Export documents

CBAM processes

Freight forwarder instructions and internal allocation of responsibilities.
