I received the following email message:

Hello Seller,

The HTS code you provided for the item(s), { 7323990000 }, is not (or no longer) valid in the US Harmonized Tariff Schedule. To ensure this entry is filed in a timely manner, please provide a valid 10-digit HTS code and update commercial invoice. (Reminder: This HTS code is used for US entry. If you provide a China HS code, it will NOT work to US entry filing. Please find the applicable one in US official website:)

If you are in need of classification assistance, please provide the following items for review:

1. Picture (include dimensions) and ASIN #

2. Material Composition

3. Intended use

Does anyone know where to get a valid 10-digit HTS code?
