HS Code for Dolomite ramming mix

Dolomite ramming mix is classified under HS code 3816.00. This heading covers refractory cements, mortars, concretes, and similar compositions, including dolomite ramming mix, other than products of heading 38.01 (graphite). Ramming mixes are unshaped refractory materials consisting of graded aggregates and binders that are compacted in situ using a pneumatic rammer or manual tool. They are essential for forming the monolithic linings of industrial furnaces, particularly in the steel industry. The classification is based on the product being a prepared chemical or mineral mixture intended for a specific industrial application (refractory lining). Because it is a mixture of minerals and binders rather than a single raw mineral, it is excluded from Chapter 25 and placed in Chapter 38.

Products Included

• Dry dolomite ramming mixes
• Wet-mixed refractory dolomite compositions
• Dolomite-based patching and repair masses
• Basic ramming mixes for electric arc furnaces
• Gunning mixes containing dolomite

Common Misclassification

Dolomite ramming mix is often confused with HS code 2518.20, which covers calcined or sintered dolomite. While calcined dolomite is a primary ingredient, the addition of binders or other minerals to create a "mix" moves the product to 3816.00. It may also be confused with HS code 3214.90 (non-refractory surfacing preparations), but the high-temperature resistance and refractory nature of the dolomite mix mandate classification in 3816.00.

FAQ

What is the HS code for Dolomite ramming mix?

The HS code for dolomite ramming mix is 3816.00.

Is this the same as refractory mortar?

While they are in the same HS heading (3816.00), ramming mixes have a different consistency and application method compared to mortars; however, for customs purposes, they share the same code.
