HTS heading 2102 is a four-digit product category for certain baking and microorganism products. It groups yeasts, whether active or inactive; other dead single-cell microorganisms, except vaccines classified in heading 3002; and prepared baking powders. The heading describes a broad product family, not one single tariff treatment.
To select the correct eight-digit HTSUS code, first identify the product’s nature and intended function, then follow the applicable subheadings and statistical subdivisions. The code may distinguish products by type, such as active versus inactive yeast, or by what the preparation contains and how it is used. Review the legal text, product ingredients, manufacturing process, packaging, and any relevant classification notes. If the product is unusual or borderline, a customs broker or binding ruling request may be appropriate.
What to check
- Confirm whether the product is yeast, another dead single-cell microorganism, or prepared baking powder.
- For yeast, verify whether it is active or inactive and document the product’s form and manufacturing process.
- Check whether the product is a vaccine or another product excluded from heading 2102 and potentially covered elsewhere.
- Read every subheading and statistical suffix rather than stopping at the four-digit heading.
- Compare the HTSUS description with the commercial invoice, ingredient list, technical data sheet, and intended use.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
