The Harmonized Commodity Description and Coding System (HS) is a recognized standardization system to classify imported/exported products for taxation and statistical reasons. The nomenclature foresees 21 sections, subdivided into 96 chapters and in above 5.000 headings and subheadings (representing individual commodities).
WHAT ARE HS CODES?
HS系统为几乎所有在国际上交易的商品定义了一个序列号，并且是国际贸易合作伙伴之间共享的参考，可以在全球范围内交换商品。
In most cases, invoices and packing lists have to report the HS number for the shipped items for Customs and statics.
Members of the World Customs Organization (WCO) have agreed to define their tariff schedules (tariffs, duties, customs) on the HS nomenclature.
关税由HS代码和进出口国安排。
An HS code is formed of 6-digits: the first two digits refer to the HS Chapter, the second two digits designate the HS heading, the last two digits are related to the HS subheading.
HS codes are used to:
- Determine customs tariffs
- 收集国际贸易统计
- Define rules of origin
- 收取内部税
- 执行贸易谈判（例如，关税优惠的WTO时间表）
- Define transport tariffs and statistics
- Monitor and track controlled goods (e.g., wastes, narcotics, chemical weapons, etc.)

The HS system has been launched in 1988 and is currently under the supervision of the World Customs Organization (WCO) – an association of over 200 countries that is based in Bruxelles.
HS FOR PROJECT MATERIALS (PIPES, VALVES, AND FITTINGS)
