Production batches, different brands have different formats.
The batch number of American production date has never been unified. This production date batch indicates the start. According to American custom, the first and last digits indicate the year. This thing is either 20 12 or 20 1 1.
Overseas imported products, including the date of production in the United States, must be marked with the corresponding date and Chinese label. But in fact, many products are purchased overseas, not domestic commodities, and have not been tested by relevant domestic departments. So the original packaging of these products in the place of origin/original sales is the packaging of the products received now.
The format of the production date in the United States is different from that in China, while most countries and regions such as Australia, Europe, America, South Korea and Japan use the EU Cosmetic Safety Management Regulations for the safety management of cosmetics, that is, cosmetics with a shelf life of more than 30 months need to be marked with the symbol of the shelf life or the effective time period after opening.
In the management of cosmetics and daily necessities in these countries, it is not necessary to mark the production date and the effective/shelf life date, but only the shelf life or the effective time period symbol after opening, and one or both of them can be marked at the same time, such as the time period symbol with a shelf life of 6 months and the time period symbol after opening 12 months.
