What is customs?

Customs is the umbrella term for all government rules, duties and procedures that must be observed in the cross-border movement of goods. These include import duties, export duties, import VAT, excise taxes and non-tariff measures such as import bans, quotas and licensing requirements. The basis of every customs clearance is the correct classification of a product in the customs tariff using the commodity code, as well as the determination of the applicable customs value. Both factors directly determine which duties are payable and which preferential arrangements can be utilised.

How does customs work in practice?

In operational logistics, customs means in concrete terms: before any cross-border shipment, all relevant trade documents — commercial invoice, packing list, proof of origin and any applicable licences — must be complete and correct. In the European Union, customs declarations are submitted electronically via the respective national customs system; incorrect or incomplete information can lead to delays, additional charges or fines. Special procedures such as inward processing, customs warehousing or temporary admission make it possible to defer or entirely avoid duties — provided all procedural requirements are fully met. Preferential trade agreements between trading partners can reduce or eliminate customs rates, but require proof of preferential origin.

For logistics and procurement, this gives rise to specific tasks:

• Ensuring data quality with suppliers, in particular correct commodity codes and origin information
• Clarifying responsibilities along the supply chain, including through Incoterms agreements
• Incorporating customs costs into the Total Landed Cost to enable realistic price comparisons
• Selecting appropriate customs procedures to optimise throughput times and capital commitment

What matters when selecting processes and systems?

Whether a company organises customs clearance in-house or through a customs agent or freight forwarder depends on volume, product complexity and available resources. In any case, the ERP and WMS systems in use must be capable of maintaining customs-relevant master data — tariff numbers, countries of origin, customs values — consistently and transferring it to customs software or authority interfaces. Audit capability is particularly important: customs authorities can audit declarations retrospectively, so all records and decision-making bases must be archived in a traceable manner. Vendor and system-side Solutions vary considerably in scope and depth of integration — which Solution is appropriate must be assessed on a company-by-company basis.
