2-(2,4-Dichlorophenoxy)propionic acid
This chlorinated aromatic acid with oxygen function, also called 2,4-DP, acts as a selective herbicide for broadleaf weed control. Explicitly named in HTS 2918.99.1800 under pesticides for aromatic carboxylic acids with additional oxygen. It mimics plant hormones to disrupt growth.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as its sodium or amine salt
Organic salts of chapter 29 acids classify with the parent acid, but may fall under heterocyclic provisions if applicable.
If for mixtures containing <95% pure active ingredient
Chemical mixtures not meeting chapter 29 purity standards shift to chapter 38 preparations.
If meeting criteria for other named pesticide acids in the heading
Intra-heading alternatives exist for similar chlorinated phenoxy acids explicitly listed.

Import Tips & Compliance
• Verify exact isomer purity as stereoisomers may affect pesticide efficacy and classification
• Include TSCA certification if used in non-pesticide industrial applications to prevent EPA scrutiny
• Avoid common pitfall of mislabeling salts; pure acid only qualifies for this specific subheading
