Classifying internal

Memory modules designed for use only or mainly with computers and computer units that are classified under heading code 8471 are classified under heading code 8473. Memory modules for use only or mainly with apparatus that are classified under a different heading code are themselves classified as part of the apparatus. Memory modules designed for use with a range of apparatus are classified under heading code 8548.

Standard dynamic random access memory (DRAM) and modules of metal oxide semiconductor (MOS) technology like single in-line memory module (SIMM) and dual in-line memory module (DIMM) are classified under subheading code 8473 30 20 10.Other standard memory modules, including non-volatile types like static random access memory (SRAM) modules, are classified under subheading code 8473 30 20 90.

Complete unitsThe following items are classified as complete units rather than as parts under various different heading codes.Power supply units (PSUs) that are specially made and suitable for use with computer units like base systems or printers are classified under subheading code 8504 40 30 90.Combined CPU fan and heatsink units for personal computers are classified under subheading code 8414 59 20 90.


Memory modules designed to be used with apparatus other than computers and computer units classified under heading code 8471 are classified under subheading code 8548 90. modules of metal oxide semiconductor (MOS) technology like single in-line memory module (SIMM) and dual in-line memory module (DIMM) are classified under subheading code 8473 30 20 10
