What is the U.S. import tariff rate for HTS 3913.90.20?
HTS 3913.90.20 (Natural polymers (for example, alginic acid) and modified natural polymers (for example, hardened proteins, chemical derivatives of natural rubber), not elsewhere specified or included, in primary forms: — Other: — Polysaccharides and their derivatives) carries an MFN general rate of 5.8% on U.S. imports; China-origin entries additionally stack Global Section 301 (CN, 12.5% tier).

Do MPF/HMF fees apply to HTS 3913.90.20?
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 3913.90.20 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 — 3913.90.20 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: /es/guides/hts-vs-hs-vs-schedule-b
