The HS Code and Strategic Goods Category Code are two different types of coding systems. The HS Code refers to the Harmonised System (HS) Code which is an international nomenclature developed by the World Customs Organisation (WCO), for the classification of goods and is harmonized at 6-digit level for use by all WCO member countries. Singapore adopts the 8-digit level HS Codes in the ASEAN Harmonised Tariff Nomenclature (AHTN), which is based on the WCO 6-digit level HS Codes, for use by all ASEAN member countries.

The Strategic Goods Category Code refers to the code for items in the Strategic Goods Control List. The List of Military Goods has Category Codes ML1 to ML22 while the List of Dual-Use Goods uses a 5-digit alphanumeric code for the items listed in it.

To determine if your product is listed as strategic goods, you will need to check the product's specifications against the Strategic Goods Control List.
