Duty Rates
General (Column 1 - MFN)
Free
This item enters the United States duty-free. No import duty is charged regardless of origin country.
Column 2 Rate (Non-Tariff Treaty Countries)
This rate applies to countries without normal trade relations (most-favored-nation status) with the United States:
Free
Column 2 rates are substantially higher than Column 1 rates and are rarely applied in modern international trade due to most-favored-nation agreements.
What HTS 2806.10.00.00 Covers
Hydrogen chloride gas and its water solution, commonly sold as hydrochloric acid or muriatic acid. This covers the chemical in any concentration, whether anhydrous gas in cylinders or aqueous acid in drums, totes, or tank cars.
Notes for Importers
Typical imports are industrial-grade hydrochloric acid for steel pickling, water treatment, pool chemicals, and chemical manufacturing, plus anhydrous HCl gas for semiconductor and chemical use. Do not confuse it with chlorosulfuric acid, which is the separate line 2806.20. Hydrochloric acid is a hazardous material, so DOT and often EPA/TSCA requirements apply alongside the tariff classification.

Frequently Asked Questions
What products are classified under 2806.10.00.00?
Hydrogen chloride in all forms: anhydrous HCl gas and aqueous hydrochloric acid, including muriatic acid sold for pools and masonry cleaning.
Does the acid concentration change the classification?
No. All strengths of hydrochloric acid, from dilute solutions to concentrated technical grades and anhydrous gas, fall under this single line.
Is a cleaning product that contains hydrochloric acid classified here?
Usually not. A formulated cleaner with other ingredients is a preparation and typically classifies in Chapter 34 or 38 rather than as the pure chemical in Chapter 28.
What is the HTS code 2806.10.00.00 used for?
HTS code 2806.10.00.00 is the harmonized tariff schedule code for Hydrogen chloride (Hydrochloric acid). This code is used to classify and identify this product type for customs clearance, duty calculation, and trade statistics.
What is the Column 2 rate for HTS 2806.10.00.00?
The Column 2 rate is the tariff duty rate applicable to goods from countries that do not have normal trade relations with the United States. This rate is typically higher than Column 1 (Most Favored Nation) rates and is rarely used in modern trade due to most-favored-nation agreements.

While not always required, using a licensed customs broker is highly recommended for most imports. A customs broker can help ensure proper HTS classification, prepare customs documentation, pay duties correctly, and avoid delays or penalties. Your broker should be familiar with Chemical Products products.

How does HTS code 2806.10.00.00 affect my import costs?
