Customs Glossary: Master Key Terms for Your Imports  

Have you come across terms like INCOTERMS, tariff classification, or customs regime, but aren’t quite sure what they mean? Understanding the customs glossary isn’t just for customs brokers—it’s crucial for importers and exporters who want to avoid fines, delays, or documentation errors.

From declaring your cargo’s value to knowing what paperwork to file, mastering these concepts can make all the difference in your international operations.

At Grupo Aduanero KAM, we guide you step by step to help you interpret and apply these customs terms properly so your processes comply with Panama’s customs regulations and operate efficiently.

Key Customs Terms You Should Know  

1. INCOTERMS  

INCOTERMS (International Commercial Terms), created by the International Chamber of Commerce (ICC), define the responsibilities between buyer and seller in an international transaction: who pays for shipping, insurance, and when the risk transfers.

Example:
In a CIF (Cost, Insurance and Freight) agreement, the seller covers transportation and insurance to the port of destination.

2. OMA Method  

The OMA Method, established by the World Customs Organization (WCO), is the international standard for tariff classification. It helps assign the correct code to your goods, which directly affects duties and customs inspections.

Example:
Wireless earbuds have a different code than wired ones, which impacts the import tax applied.

3. DUA (Single Administrative Document)  

The DUA is the official form used to declare goods to customs authorities. It includes details like the value, origin, nature of the goods, and under which customs regime they’re being imported.

Example:
Before customs clearance, the DUA must state whether the goods are for permanent import, temporary use, or in transit.

4. CIF Value  

The CIF value (Cost + Insurance + Freight) is the base value for calculating customs duties. It includes the merchandise price plus shipping and insurance up to the destination port.

Example:
If the item costs $3,000, with $400 in shipping and $100 in insurance, the CIF value is $3,500.

5. Customs Regime  

This refers to the set of rules that determine how the goods will be processed by customs. There are different types of customs regimes such as definitive import, temporary admission, free zones, or bonded transit.

Example:
If you’re importing machinery for a project that only lasts six months, you may use a temporary customs regime and delay tax payments.
