Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically formulated as wood preservative
Pesticide-formulated products containing zinc chloride as active ingredient classify in Chapter 38.
If synthetic organic pigments containing zinc chloride
Pigments and preparations shift to Chapter 32 if color-producing, not pure inorganic salts.
If mixed with mineral nutrients for fertilizer
Mixtures for fertilizer use containing zinc compounds classify in Chapter 31 per exclusions.

Import Tips & Compliance
• Declare water of hydration percentage accurately; affects duty calculation and storage requirements
• EPA registration required for wood preservative uses; provide SDS with environmental hazard data
• Avoid shipping in paper bags—use moisture-proof HDPE drums to prevent dissolution en route
