The slack season for the luggage industry can vary depending on the region and market, but generally, it is during the off-peak travel season. But with the end of the pandemic and the need for travel, more and more people are buying luggage.
In North America and Europe, this is typically during the winter months (December to February) and the shoulder seasons of fall (September to November) and spring (April to June) when there are fewer holiday and leisure travel. However, in other regions or markets, such as in some tropical destinations, the off-season may be during the summer months when temperatures can be quite high.

It’s important to note that while the luggage industry may experience lower sales during slack seasons, there can still be demand from business travelers, students, and other groups who travel year-round.
In China, the off-season of the luggage industry is around May. Because people will start purchasing in the New Year and finish the production in March and April, the luggage industry will be relatively weak in May. However, it will start to pick up again around June to prepare for the purchase of luggage by students in the next back-to-school season in September.
Therefore, friends who need suitcases can also purchase Chinese trolley bag during the off-season in May, otherwise the production cycle will be elongated in the peak season, because of the need to arrange orders.
