The customs allowance is the amount of products you can take across the border on the way back to your country without having to declare them, and therefore without having to pay. Although in some agricultural products (coffee, alcohol, tobacco and similar products), this limit refers to amounts, in others (milk, butter, cheese, sweets, etc.) the value and quantity are both taken into account.
The allowances for all industrial products except for perfumes and colognes are established by their value in Euros.
If it is not otherwise indicated, the allowances are for people over age and cannot be accumulated either in value or between travellers, or between agricultural and industrial products.
