HS Tariff Classification

Definitions #

Assigning a six-digit international code (Harmonized System) to a product for customs duty and trade statistics purposes.

Technical The legal determination of a product's heading and subheading under the WCO Harmonized System nomenclature, which then determines applicable duty rates and trade measures.

Etymology #

From 'Harmonized Commodity Description and Coding System' (abbreviated HS) + 'tariff' (duty schedule) + 'classification'.

Collocations #

HS code 商品海关编码，一般最少6位，可扩展至10位
binding tariff information (BTI) 海关发布的具有法律约束力的归类裁定
tariff shift rule 关税税则归类改变规则（贸易协定中判定原产地）

Real Business Examples #

The customs agent verified that the product's HS tariff classification under heading 8471 was correct before submitting the import declaration.
Inflatable mattresses are often misclassified under heading 3926 instead of 9404, causing quota and duty discrepancies.

Common Errors #

只根据商品名称而非用途和材料进行归类归类应依据‘归类总规则’（GIRs），先确定品目（heading）再考虑子目，使用官方注释
误以为 HS 代码仅是6位，忽略国家子目扩展 6位是国际统一，之后两位或四位（如8位/10位）为国家特定细分，需使用目标国税则

Confusable Terms #

ECCN (Export Control Classification Number) vs HS Tariff Classification: ECCN 是出口管制编号，用于判断是否需要出口许可，而非关税归类；两者目的不同

Frequently Asked Questions

同一商品在不同国家的 HS 代码是否完全一致？?

前6位相同，但很多国家增加了更细分的子目（如8位/10位），因此完整代码可能不同

如何获得官方的 HS 归类结论？?

可向海关申请进口前裁定（如美国的 CBP Ruling）或欧盟的 BTI（约束性税则归类信息），具有法律约束力
