Column 31 of the goods declaration "Cargo spaces and description of goods – Labeling and quantity – Container numbers – Quantity and distinguishing features" is intended to reflect detailed information that allows identifying the declared goods and comparing the information stated in the declaration with the goods actually being transported.
What should be considered when filling in this column?
When declaring a product to a foreign economic activity participant, it is necessary to ensure the completeness, reliability and unambiguity of its description.
In column 31, depending on the nature of the goods and the specifics of their movement, the information necessary for their identification is indicated, including: the name of the goods; information about the model, brand, article and other distinctive characteristics; composition, material of manufacture and main technical characteristics (if they are relevant to the identification of the goods); information about the manufacturer and trademark (if applicable); quantity of goods and unit of measurement; information about packaging, cargo items and their labeling; container numbers, if the goods are transported in containers; other information provided by the customs legislation and necessary for the identification of the goods.
Important: the product description must be specific and informative.
The use of exclusively general formulations that do not allow us to unambiguously determine the characteristics and type of product, may lead to the need for additional clarification of information and additional control measures.
For example, instead of a general description of "equipment", "spare parts", "plastic products", "electronics", it is necessary to specify the specific name and characteristics of the product that allow it to be identified.
Why is this important?
The information contained in column 31 is used by customs authorities during customs control, including for: identification of goods; verification of compliance of the declared information with the submitted documents; comparison of the declaration data with the goods actually transported; determination of applicable customs tariff and non-tariff regulation measures; verification of compliance with established prohibitions and restrictions; application of a risk management system; conducting subsequent customs control.
Thus, the more accurately and fully the product is described, the less likely there are to be questions during its customs clearance.
It is recommended that participants in foreign economic activity check the compliance of the information in column 31 with commercial, transport and other documents accompanying a foreign economic transaction before submitting the DT.
The SRC urges participants in foreign economic activity to take a responsible approach to filling out declarations for goods. A complete and reliable description of the goods contributes to more effective customs control, reduces the number of additional requests and reduces the risk of delays in customs operations.
At the same time, we would like to inform you that administrative liability is provided for violating the procedure for filling out a declaration for goods.
