HS Code for Silicon Dioxide 2025 (2811.22)

**TL;DR:** The **HS code for silicon dioxide** is 2811.22 under Chapter 28. This 2025 guide details classification, regional updates, forms, uses, and compliance for importers and e-commerce shippers.
2025 HS Code Updates for Silicon Dioxide by Region
RegionBase HS Code2025 ChangesKey Impacts
United States (HTS)2811.22USPS full HTS required Sep 1; de minimis exemption endsHigher duties on silica imports, e.g., 10-25% for related products
GCC Countries2811.22.0012-digit codes mandatory Jan 1 (Kuwait, Oman, Qatar, Saudi)Precise classification for silica in electronics
European Union2811.22.10Combined Nomenclature updates for environmental subheadingsAffects silica gel and chemical exports
Global (WCO)2811.22National adaptations; no WCO revision until 2027Focus on tariff compliance 2025

What is the HS Code for Silicon Dioxide in 2025?

The primary HS code for silicon dioxide remains 2811.22 in 2025.** Known as SiO2 or silica, it falls under Chapter 28: Inorganic chemicals.

  • Heading 2811: Other inorganic acids and oxygen compounds of non-metals
  • Subheading 2811.22: Silicon dioxide
  • Applies to pure forms and compounds in international trade
  • Source: WCO HS Nomenclature 2022 (valid through 2026 nationally)
  • Use for customs declarations worldwide

This code ensures accurate tariff classification for silicon dioxide imports and exports.

Key 2025 HS Code Changes Affecting Silicon Dioxide

While WCO HS sees no global revision until 2027, 2025 introduces critical national HS code changes.**

  • US: End of de minimis for USPS parcels from Sep 1 requires full HTS 2811.22
  • GCC: Expansion to 12-digit HS codes impacts silicon dioxide in tech shipments
  • EU: Combined Nomenclature 2025 refines chemical subheadings
  • Other regions: National tariff compliance 2025 tweaks for e-commerce
  • Importers must verify silicon dioxide HS code updates regionally

These shifts emphasize precise HS classification to avoid delays.

Forms of Silicon Dioxide and Their HS Codes

All silicon dioxide forms classify under HS code 2811.22, with descriptive specifications.**

  1. Quartz (crystalline silica): Used in electronics and optics
  2. Silica gel (amorphous): Common desiccant in packaging
  3. Fumed silica: Thickening agent for paints and adhesives
  4. Precipitated silica: Reinforces tires and rubber products
  5. Fused silica: High-purity for semiconductors

Specify form in declarations to match exact subheadings where applicable.

How to Find the Correct HS Code for Silicon Dioxide: 2025 Step-by-Step

Use this 5-step guide to determine the HS code for silicon dioxide accurately in 2025.**

  1. Examine product composition: Confirm SiO2 purity and form (powder, gel, crystal)
  2. Locate Chapter 28: Inorganic chemicals; oxygen compounds of non-metals
  3. Select heading 2811.22: Matches silicon dioxide description
  4. Apply regional 2025 updates: Check US HTS, EU CN, GCC 12-digit via official tools
  5. Document precisely: Include form, purity, and end-use for customs

This process targets featured snippet potential for quick reference.

Common Uses of Silicon Dioxide Requiring HS Code 2811.22

Silicon dioxide serves diverse industries, all needing HS code 2811.22 for trade.**

  • Electronics: Fumed and fused silica in semiconductors
  • Pharmaceuticals: Precipitated silica as excipient
  • Food industry: Anti-caking agent (food-grade silica)
  • Construction: Quartz in glass and concrete
  • Packaging: Silica gel desiccants

Accurate classification prevents duty miscalculations across sectors.

Risks of Incorrect HS Code for Silicon Dioxide in 2025

Misclassifying silicon dioxide HS code 2811.22 leads to severe 2025 trade penalties.**

  • Customs delays and storage fees
  • Fines up to 100% of shipment value
  • Increased duties from wrong tariff rates
  • Loss of FTA preferences
  • Seizure for e-commerce non-compliance

Prioritize tariff compliance 2025 to mitigate these issues.

2025 Case Study: Silicon Dioxide Import Success

A US importer of silica gel faced delays post-de minimis end but resolved with proper HS code 2811.22.**

  • Challenge: 25% shipment holds in Q1 2025
  • Solution: Verified HTS classification and descriptions
  • Result: Clearance in 2 days, $15K duty savings
  • Lesson: Early 2025 HS code verification pays off
  • Citation: WCO guidelines on national adaptations
