Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 292521 when importing or exporting imines and their derivatives, such as chlordimeform, a common agricultural chemical. This code specifically covers imines, which are organic compounds characterized by a carbon-nitrogen double bond.
This code is distinct from HS-6 292529, which includes other carboxyimide-function compounds. If your product is a derivative of an imine but does not fall under the specific criteria of 292521, you may need to consider alternative classifications.
When shipping products like chlordimeform, ensure that your documentation accurately reflects the chemical structure. This helps in avoiding delays at customs and ensures compliance with regulations.
Imines can be used in various applications including pharmaceuticals and agrochemicals. If you're dealing with a product that contains an imine structure, this HS-6 code will likely be applicable.
