Checked and not applied
- Section 301 forced labor: Exempt: article is already subject to Section 232 duties (9903.05.90, U.S. note 52)
- Section 232: Section 232 semiconductor duty (proclamation of Jan 14, 2026, effective Jan 15, 2026): 25% applies ONLY to advanced computing accelerators meeting the TPP/DRAM-bandwidth thresholds — covered articles enter under HTSUS 8471.50 / 8471.80 / 8473.30 with HTSUS 9903.79.01. Standard logic, memory, and analog chips under 8542 and ordinary computer units/parts are NOT subject. Exemptions: US data centers (9903.79.03), repair/replacement (9903.79.04), R&D (9903.79.05), startups (9903.79.06), consumer electronics (9903.79.07), civil industrial (9903.79.08), public sector (9903.79.09). Not auto-applied: the technical thresholds cannot be determined from the HTS code alone.
Stack priced from China on a $10,000 customs value, ocean entry. Other origins carry different programs; the calculator prices any of them.
