3808.61 - In packings of a net weight content not exceeding 300 g:

This HTS category, 3808.61, specifically covers insecticides, rodenticides, fungicides, herbicides, antisprouting products, plant-growth regulators, disinfectants, and similar products when they are packaged for retail sale with a net weight content *not exceeding 300 grams*. This precise weight limitation is the defining characteristic of this subdivision, ensuring that only smaller retail-sized units fall under this heading.

Distinguishing this category from its siblings is straightforward. HTS 3808.62 addresses similar products but in larger retail packings, specifically those exceeding 300 grams but not exceeding 7.5 kilograms. HTS 3808.69 encompasses other forms or packings not meeting the specific weight criteria of 3808.61 or 3808.62. Therefore, the net weight of the retail packaging is the critical differentiator between these sibling categories.

Within HTS 3808.61, further subdivisions exist to refine classification based on the active ingredient. HTS 3808.61.10.00 is dedicated to products containing any aromatic or modified aromatic pesticide, indicating a focus on the chemical nature of the active substance. The residual category, HTS 3808.61.50.00, is for all other products within the 300-gram retail packing limitation that do not fall under the aromatic pesticide specification, offering a comprehensive classification for a broad range of smaller packaged pest control and plant care items.
