Single or multiple seizures
A single seizure is where only one category is seized on a particular occasion (e.g. caviar).
A multiple seizure is where two or more category types (e.g. caviar and timber) are seized on a particular occasion. The occasion is counted once in the total number of seizures, but a seizure is counted against each category.
Example: A seizure is made of caviar and timber. This seizure would be counted as:
Total seizures: One seizure in the overall total for the number of seizures.
Category type: One seizure of caviar; one seizure of timber or wood products
