HS Code 2842Salts of inorganic acids or peroxoacids, n.e.c. including aluminosilicates whether or not chemically defined, but excluding azides

2 six-digit codes · Heading 41 of 50 in Chapter 28 · World Customs Organization Harmonized System

HS code 2842 is a catch-all heading for salts of inorganic acids that no more specific heading in Chapter 28 names. Use this page to see what fits, what does not, and how to choose between its two subcodes.

The WCO writes heading 2842 as a residual bucket: goods of Chapter 28that answer to “Salts of inorganic acids or peroxoacids, n.e.c. including aluminosilicates whether or not chemically defined, but excluding azides” and that no more specific heading in the chapter already claims. It still carries 2 six-digit codes, 284210 through 284290, so “other” is not the end of the classification here. The heading is number 41 of 50 in Chapter 28, Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes, which runs to 180 six-digit codes in all.

Six-digit codes under heading 2842

HS CodeImport–export description
284210Salts of inorganic acids or peroxoacids, double or complex silicates, including aluminosilicates, whether or not chemically defined, excluding azides
284290Salts; of inorganic acids or peroxoacids, other than double or complex silicates, including aluminosilicates, whether or not chemically, excluding azides

What HS code 2842 covers

Heading 2842 is a residual heading. It holds salts of inorganic acids or peroxoacids that are not named anywhere else. The short form n.e.c. means "not elsewhere classified". Aluminosilicates belong here, whether or not they are chemically defined. Azides are left out.

The heading sits in Chapter 28, inorganic chemicals, which is part of Section VI, chemical products. You may also see it written as HS heading 2842, HSN code 2842 or HTS code 2842. The first four digits are the same in each system. Countries add their own extra digits after that for tariff classification.

HS 284210 vs 284290: which six-digit code fits?

The two subcodes split the heading by the type of salt. The question to ask is simple: is my product a double or complex silicate?

  • Use it when the product is a silicate of this kind.
  • Use it when the salt is not a double or complex silicate.

How to classify salts of inorganic acids correctly

Always look for a more specific heading before you settle on 2842. Because it is a residual heading, it is the last stop, not the first. Work through these checks in order:

  • Plain silicates and commercial alkali metal silicates go to HS 2839, silicates.
  • Check this one first if your salt contains a metal inside the acid part, as dichromates and similar salts do.
  • Sulphates, nitrates, phosphates and carbonates have their own headings: 2833, 2834, 2835 and 2836.
  • Azides are not part of 2842. Look at HS 2850, which covers hydrides, nitrides, azides, silicides and borides.

Straight answers

HS Code 2842: common questions

Are aluminosilicates classified under HS 2842?

Yes.

What is the difference between HS 284210 and 284290?

284290 is for every other salt of an inorganic acid or peroxoacid in the heading.

Are azides included in HS 2842?

No. The heading excludes azides. They are covered by heading 2850, together with hydrides, nitrides, silicides and borides.

Are dichromates classified under 2842 or 2841?

Check 2841 first, because it covers salts of oxometallic or peroxometallic acids. Heading 2842 is residual and takes only the salts that no more specific heading claims.
