HS Code 3816Refractory cements, mortars, concretes and similar compositions, including dolomite ramming mix, other than products of heading 38.01
1 six-digit code · Heading 16 of 27 in Chapter 38 · World Customs Organization Harmonized System
HS code 3816 is the customs heading for refractory cement, mortar, concrete and ramming mix. This page shows what fits here, what does not, and where to find the trade records.
Heading 3816does not subdivide further in the WCO nomenclature: goods answering to “Refractory cements, mortars, concretes and similar compositions, including dolomite ramming mix, other than products of heading 38.01” classify at the single six-digit code 381600. The heading is number 16 of 27 in Chapter 38, Chemical products n.e.c., which runs to 108 six-digit codes in all.
Six-digit codes under heading 3816
| HS Code | Import–export description |
|---|---|
| 381600 | Refractory cements, mortars, concretes and similar compositions, including dolomite ramming mix, other than products of heading 38.01 |
What heading 3816 covers
Refractory materials stand up to extreme heat. Furnaces, kilns, ladles and boilers are lined with them. This heading covers the cements, mortars and concretes used to build or repair those linings.
Buyers often call the ready-to-cast concretes castables. It is a dry material made from dolomite. Workers pack it tightly into place to form a lining.
The heading works as a catch-all for prepared refractory mixtures. A product lands here when it is a refractory compound and no other heading describes it more closely.
HS 381600 and national tariff lines
The six-digit level is the part of the code that every country shares. Each country may add more digits for its own tariff lines. So a customs form in your market can show a longer number that starts with 381600.
Those extra digits, and any duty or tax tied to them, are set locally. Check your own tariff for them. In India the same code is usually called an HSN code, and the first six digits match.
Because the base code is shared, 381600 is the right starting point for tariff classification and for searching trade records across borders.
HS code 3816 vs 3801: graphite refractory and look-alikes
The wording of this heading leaves out anything that belongs in heading 38.01. That heading covers artificial graphite and preparations based on graphite or other carbon, sold as pastes, blocks, plates or other semi-manufactures. A graphite-based refractory paste therefore goes to 3801.
Two other headings in the same chapter are easy to mix up with it:
- 3824 covers prepared binders for foundry moulds or cores, and chemical preparations not named elsewhere. A binder for a foundry mould is not a refractory cement.
- 3815 covers catalysts and reaction starters. These speed up chemistry. They do not line furnaces.
Unsure which heading fits?
Many products in this chapter look alike on paper. If your goods are not a refractory cement or mortar, a neighbouring heading may be a better fit. Browse the sibling headings from the chapter page, or run your product description through the HS code classifier.

HS Code 3816: common questions
What is HS code 3816?
Products of heading 38.01 are left out.
What is the HS code for dolomite ramming mix?
Dolomite ramming mix is named in the wording of heading 3816. Its six-digit code is 381600.
Under which chapter does HSN code 3816 fall?
It sits in Chapter 38, which belongs to Section VI of the Harmonized System. The chapter groups chemical products not named elsewhere.
