For international shipping from the U.S., which 6-digit export codes are people using for USPS customs forms for...cotton t-shirt, a 50/50 cotton t-shirt and 50/50 sweatshirts?
Here is the link to the search engine, but I've found it sort of confusing. Is a regular t-shirt considered knitted / crocheted?
