Hello:? 6? 9? 6? The "T-shirt" in the Customs Tariff refers to a light knitted or crocheted underwear garment with cotton or chemical fiber as raw material, which is made of velvet-free, cut velvet or terry weave fabric, single color or multi-color, with or without pockets, tight-fitting long sleeves or short sleeves, no collar, no buttons, no neckline and high and low openings (round, square, boat-shaped or V-shaped neckline). Besides lace, this kind of clothing can also be printed, knitted or decorated with advertisements, pictures or words in other ways, and its hem is usually sewn. ? 6? 9? 6? According to the above definition, clothes that we can wear outside in our daily life, especially clothes with collars, cannot be regarded as "T-shirts" listed in the customs tariff. If you are satisfied with my answer, please adopt it and give it a good comment. Thank you!
