Last updated: April 2026 dataChapter 31 fertilizer products packaged in tablets, lozenges, or retail packages not exceeding 10 kg enter under 3105100000, a presentation-based classification that applies regardless of the underlying nutrient type. Vietnam and Mexico are the leading suppliers, reflecting their established horticultural and consumer-goods manufacturing sectors. This heading is heavily oriented toward retail garden and houseplant products, so packaging compliance — including label requirements for nutrient content claims — is as important as tariff classification for importers.

The threshold applies to the net weight of the product per package. A shipment of many small packages each not exceeding 10 kg net qualifies for this heading even if the total shipment weight is large, provided each individual retail unit meets the weight limit.
Fertilizers sold in the US are primarily regulated at the state level under individual state fertilizer laws, which typically require guaranteed analysis labels showing nitrogen, phosphate, and potash percentages. Importers should verify compliance with the destination state's labeling rules before distribution, as requirements vary and non-compliant labeling can result in product holds or recalls.
