la douane

The French word "douane" refers to customs — the government authority or department responsible for controlling the import and export of goods, collecting duties or taxes, and enforcing regulations at borders such as airports, ports, and land crossings.

Meaning:

• Douane = Customs (border control)
• It is the place or service where travelers' luggage and cargo are checked to prevent illegal goods, collect tariffs, and apply trade regulations.

Related words and differences:

• Douane vs Porte d'entrée (entry point): "Douane" refers to the customs authority itself, while "porte d'entrée" is just a literal entrance, not necessarily involving customs.
• Douane vs Fiscalité (taxation): Taxes can be broader, including income tax, VAT etc., while "douane" specifically relates to import/export duties at borders.
• Douanier: The officer who works at the customs ("douane").

In summary, "douane" strictly relates to border customs controls and administration dealing with goods crossing international borders.
