HS Code 391390: 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 in Sri Lanka

Q: Is HS code 391390 the same across all countries?

Yes — up to the 6-digit level, HS code 391390 is the same in every WCO member country. Beyond 6 digits, each country extends the code for national tariff and statistical use. Sri Lanka extends it under HS-LK.
