π Phosphoric Acid Resistant Repair Mortar
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Understand βRepair Mortarβ?
Phosphoric Acid Resistant Repair Mortar is a specialized industrial construction material designed to repair and protect surfaces exposed to harsh chemical environments, particularly phosphoric acid. It is typically composed of high-performance cementitious materials, fine aggregates, and chemical additives that provide exceptional resistance to acidic corrosion.
In international trade, this product falls under the broader category of chemical products and building materials. The key distinction lies in whether it is classified as a generic construction material or a specialized chemical preparation.
β οΈ Key Distinction:
- If the product is primarily a cement-based mortar with specific chemical resistance properties, it may be classified under Chapter 32 (Prepared Binders for Foundry Molds and Cores; Chemical Products and Preparations Not Elsewhere Specified or Included).
- If it is considered a general construction material without specific chemical formulation details, it may fall under Chapter 38 (Miscellaneous Chemical Products) or Chapter 25 (Salt; Sulphur; Earths and Stone; Plastering Materials and Lime and Cement), depending on the exact composition and intended use.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Chemical Resistance |
|---|---|---|---|
3214.10.00.90 |
Glaziers' putty, grafting putty, resin cements, caulking compounds and other mastics; painters' fillings; nonrefractory surfacing preparations for facades, indoor walls, floors, ceilings or the like: Glazier's putty, grafting putty, resin cements, caulking compounds and other mastics; painters' fillings Painters' fillings | Industrial flooring, wall coatings, chemical plant repairs | β Yes (Phosphoric Acid Resistant) |
3214.90.50.00 |
Glaziers' putty, grafting putty, resin cements, caulking compounds and other mastics; painters' fillings; nonrefractory surfacing preparations for facades, indoor walls, floors, ceilings or the like: Other: Other | General industrial repairs, non-specific chemical resistance | β Yes (General Chemical Resistance) |
π Key Reminder:
- The classification depends on the specific formulation and intended use of the mortar.
- If the product is explicitly marketed as phosphoric acid resistant, it is more likely to fall under 3214.10.00.90 due to its specialized nature.
- If the product is a general-purpose repair mortar with incidental chemical resistance, it may fall under 3214.90.50.00.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
