Description
Memories (integrated circuits)
HS Code 854232 covers memory integrated circuits (ICs) and is duty-free under the US MFN tariff.
Frequently Asked Questions
What are the critical packaging and transportation requirements for shipping integrated circuit memory chips under HTS 854232 to prevent electrostatic discharge (ESD) damage?
Memory chips under HTS 854232 must be shipped in static-shielding packaging, such as conductive foam or bags, clearly marked with ESD warning symbols. Temperature-controlled air freight is often used for high-value or sensitive shipments to prevent damage from condensation and thermal stress. Proper documentation must specify the ESD-sensitive nature of the goods to ensure careful handling throughout the logistics chain.
What are the specific U.S. import restrictions for memory chips (HTS 8542.32) under Section 301 tariffs?
Memory chips from China classified under HTS 8542.32 are subject to an additional 25% ad valorem tariff under the U.S. Section 301 action (List 1). This duty is assessed in addition to the column 1 general rate of duty. Importers must use HTSUS subheading 9903.88.01 to report this additional duty.
Under HTS 854232, how does the presence of a controller or logic function affect the classification of a memory chip?
A memory chip with an integrated controller or additional logic functions is typically excluded from heading 8542 and may be classified elsewhere, as heading 8542 is strictly for 'memories' without other primary functions. For example, a solid-state drive (SSD) controller makes the device a 'storage unit' classifiable under 8471, not a 'memory' under 8542.
Country Import Restrictions Notes
Memory chips (854232) are generally not subject to broad country-specific import embargoes, but they are highly sensitive to export controls due to their dual-use nature. The most significant restrictions are U.S. export controls under the EAR (15 CFR § 744), which prohibit or require licenses for shipments to specific entities and end-users in countries like China, Russia, and Iran, particularly for advanced memory technologies. Importers must also be aware of anti-dumping and countervailing duty (AD/CVD) orders; for example, the U.S. has AD/CVD orders on DRAM modules from China and Taiwan (case numbers A-570-929 and A-583-859). Always verify the latest Commerce Department BIS lists and Treasury Department OFAC sanctions for the specific consignee and end-use before shipping.
Common Classification Mistakes for Memory Chips
A frequent error is misclassifying memory modules (e.g., DRAM modules) under 8542.32 for the individual memory chips (dies) they contain. Complete memory modules, such as SIMMs or DIMMs, are generally classified elsewhere, often under heading 8473 as parts of automatic data processing machines. Additionally, ensure the chips are not monolithic integrated circuits for other specific functions, like graphics processors or controllers, which fall under other subheadings of 8542. Always verify the primary function and packaging to avoid these costly classification errors.
