Declaration Item Analysis: PLINTH - HS Code Breakdown & Customs Guidance
This report details the customs implications of the declared items, focusing on HS codes, tax rates, and essential considerations for import/export.
Understanding HS Codes:
The Harmonized System (HS) code is a globally standardized system of names and numbers used to classify traded products. It's crucial for determining tariffs, regulations, and statistical tracking. Here's a breakdown of the provided HS codes:

- 10: Articles of cement, concrete or artificial stone.
- 11: Tiles, flagstones, bricks and similar articles.
- 00.10: Building blocks and bricks Containing by weight more than
70 percent magnesia, expressed as MgO, with carbon content ranging from trace amounts to less than30 percent , and chemically bonded by resin or pitch.
Tax Implications:
- Basic Tariff: 3.2%
- Additional Tariff: 25.0%
- Post April 2nd, 2025: Additional Tariff increases to 30.0%
- Total Tax: 58.2%
Important Notes:
- Magnesia Content: The HS code specifically targets products with >70% magnesia content. Ensure your product meets this specification.
- Resin/Pitch Bonding: The chemical bonding method (resin or pitch) is a defining characteristic.
- Documentation: Provide a detailed composition report to confirm the magnesia content and bonding agent.
2. Builders' Joinery and Carpentry of Wood (HS Code: 4418.91.91.05)
