Harmonized System (HS) Code for Crusher Backing Compound
Crusher backing compounds are essential materials used in the mining and construction industries to protect and reinforce crushing machinery. These compounds are typically epoxy-based resins designed to fill gaps between wear liners and crusher frames, ensuring optimal performance and longevity of equipment. If you are involved in the import or export of crusher backing compounds, understanding the correct Harmonized System (HS) code is crucial for compliance with international trade regulations.
Understanding HS Codes for Crusher Backing Compounds
The Harmonized System (HS) is a standardized classification system used globally to categorize traded products. Crusher backing compounds generally fall under the category of chemical products or adhesives, depending on their composition.

The most applicable HS code for crusher backing compounds is:
- 3506: Prepared glues and other adhesives, not elsewhere specified or included.
- Subcategory: 3506 91 00 – Epoxy resins in primary forms.

Since most crusher backing compounds are epoxy-based, this classification ensures proper customs clearance and avoids misclassification penalties. However, if the product contains additional additives or differs significantly in composition, it may fall under a different subcategory within Chapter 35 or related chemical classifications.
Why Accurate HS Code Classification Matters
1. Customs Compliance: Incorrect HS codes can lead to shipment delays, fines, or confiscation of goods.
2. Tariff Determination: The correct code ensures accurate duty and tax calculations.
3. Trade Documentation: Proper classification simplifies export/import documentation and logistics processes.
Additional Considerations for Exporters & Importers
- Verify with local customs authorities for any country-specific variations in HS coding.
- Ensure product descriptions match the HS code to avoid discrepancies during inspections.
- Consult a trade specialist if the compound has unique properties that may require a different classification.
By using the correct HS code (3506 91 00 for epoxy-based crusher backing compounds), businesses can streamline international trade operations while adhering to regulatory requirements. Always double-check with updated customs databases or seek professional advice to confirm the appropriate classification for your specific product variant.
