HS Code for Plant growth regulator

Plant growth regulators (PGRs) are classified under HS code 3808.93. These substances are distinct from fertilizers because they do not provide essential nutrients like nitrogen or phosphorus; instead, they are chemical compounds that alter the physiological processes of a plant. This includes substances that promote, inhibit, or otherwise modify plant growth, flowering, or fruit ripening. The classification under 3808.93 is determined by the product's function as a regulator and its presentation as a preparation or retail-ready product. Chapter 38 covers miscellaneous chemical products, and heading 3808 specifically groups pesticides and growth regulators. The Harmonized System distinguishes these from pure hormones (which might fall under Chapter 29) by looking at whether the product is a "preparation"—meaning it has been mixed with other substances to facilitate application. This code is essential for regulating the import of agricultural stimulants and ensuring they meet local environmental and safety standards.

Products Included

• Auxins and Gibberellins for fruit set enhancement
• Cytokinins for cell division promotion
• Ethylene inhibitors for shelf-life extension
• Rooting hormones in powder or gel form
• Anti-sprouting products for potato storage

Common Misclassification

The most frequent misclassification occurs with HS code 3105, which covers fertilizers. Importers often confuse growth stimulants with nutrients. Another common error is using HS code 3808.93 for herbicides; while they share the same subheading level in some tariffs, herbicides are technically distinct, though they are grouped in the same 3808.93 category in many international versions. Pure synthetic hormones may also be wrongly placed in 2937.

FAQ

What is the HS code for plant growth regulator?

The HS code for plant growth regulators, including anti-sprouting products, is 3808.93.

Are seaweed extracts classified here?

If the seaweed extract is marketed primarily as a growth regulator and contains added chemicals to perform that function, it may fall under 3808.93; however, pure organic seaweed fertilizers are often classified under 3101.
