Perguntas frequentes
What is the U.S. import tariff rate for HTS 3818.00.00?
HTS 3818.00.00 (Chemical elements doped for use in electronics, in the form of discs, wafers or similar forms; chemical compounds doped for use in electronics) carries an MFN general rate of Free on U.S. imports; China-origin entries additionally stack Global Section 301 (CN, 12.5% tier). Example (origin CN · $10,000 · sea formal entry): duties + fees ≈ $1,297.14.Data as of 2026-10-07 (ruleset v0.3.4).
Do MPF/HMF fees apply to HTS 3818.00.00?
Yes. Fees are not duties and are charged per entry: Harbor Maintenance Fee (HMF) 0.125%; Merchandise Processing Fee (MPF) 0.3464% (once per entry, min $34.58 / max $670.86). ≈ $47.14 on the $10,000 formal-entry example; postal shipments ≤$2,500 use informal entry with fixed fees instead.
How does HTS 3818.00.00 differ from an HS code and Schedule B?
All three share the same root: HS is the World Customs Organization's 6-digit international baseline; HTS is the 10-digit U.S. import classification (first 6 digits identical to HS — 3818.00.00 on this page is shown at the 8-digit HTS level); Schedule B is the U.S. export code (first 6 digits match HTS, with Census-specific 8–10 digit suffixes). Use this HTS code for U.S. import duty, and Schedule B when exporting from the U.S. Full comparison: /pt/guides/hts-vs-hs-vs-schedule-b
