We ship educational materials all over the world. Some orders have several hundred different sku's of very similar items that could be grouped under one customs declaration. we did not realize SS had a limit of 100 customs declarations. So on one of our larger orders of 100+ Skus, an error message comes up, "maximum number of items exceeded." Is there a way within ship station to mark items for grouping under one category/harmonization code, thereby reducing the number of customs declarations? At this point we are either having to split shipments, or manually group the items under several declarations. Thanks very much!
