What types of products fall under HS-4 2512?

HS-4 2512 covers siliceous fossil meals, including kieselguhr, tripolite, and diatomite, whether calcined or uncalcined.

How do I know if my product has a specific gravity of 1 or less?

You can determine specific gravity through testing. Products with a specific gravity of 1 or less qualify for this HS code.

Are there any additional regulations for importing siliceous earths?

Yes, ensure compliance with any local regulations regarding the use and handling of siliceous materials.

Can I use HS-4 2512 for processed diatomaceous earth?

Yes, both processed and unprocessed diatomaceous earth fall under HS-4 2512 as long as they meet the specific gravity requirement.

What documentation is needed for customs clearance under HS-4 2512?

You will need a commercial invoice, packing list, and any relevant certificates confirming the product's specific gravity.

HS-4 · Heading

2512 — Siliceous fossil meals (e.g. kieselguhr, tripolite and diatomite) and similar siliceous earths; whether or not calcined, of an apparent specific gravity of 1 or less

Chapter 25: Salt; sulphur; earths and stone

Plain-language overview

Use HS-4 2512 when importing siliceous fossil meals such as kieselguhr, tripolite, or diatomite. For example, if you're shipping diatomaceous earth for use in filtration or as an absorbent, this code applies. It covers both calcined and uncalcined forms with a specific gravity of 1 or less.

When deciding between HS-6 lines, note that 251200 encompasses all types of siliceous fossil meals, regardless of their processing state. If your product is a natural diatomite or a processed version, it still falls under this code. Be aware that specific gravity is a key factor in classification.

If you are unsure about the specific gravity of your product, conduct a test to confirm it is 1 or less, as this will determine eligibility under this heading. This classification is crucial for customs clearance and determining applicable duties.
