Singapore HS Code

HS Code 850431: Electrical transformers, static converters (for example, rectifiers) and inductors : Other transformers : Having a power handling capacity not exceeding 1 kVA in Singapore

Q: What is HS code 850431 in Singapore?

HS code 850431 covers Electrical transformers, static converters (for example, rectifiers) and inductors : Other transformers : Having a power handling capacity not exceeding 1 kVA in Singapore. It sits in Chapter 85 (Electrical machinery and equipment and parts thereof; sound recordersand reproducers, television image and sound recorders and reproducers, and parts andaccessories of such articles), Heading 8504 of the Harmonized System, and is classified under STCCED / HS-SG.

Q: Is HS code 850431 the same across all countries?

Yes — up to the 6-digit level, HS code 850431 is the same in every WCO member country. Beyond 6 digits, each country extends the code for national tariff and statistical use. Singapore extends it under STCCED / HS-SG.

Q: What system does Singapore use to classify HS code 850431?

Singapore classifies products under the Singapore Trade Classification, Customs & Excise Duties 2022 (STCCED / HS-SG; locally STCCED 2022), which extends HS codes to 8 digits. The first 6 digits align with the WCO Harmonized System, and the rest cover national tariff and statistical needs.
