Common mistakes with Rat / rodent poison

• Assuming the rules at the origin apply at the destination — they don't. The destination customs authority is the binding rule.
• Travelling and posting are treated differently: an item you can carry may be prohibited by post (and vice versa).
• Personal vs commercial intent: above a quantity threshold, customs may treat your shipment as commercial regardless of intent.
• Undervaluing on the customs declaration to avoid duty — treated as fraud in most jurisdictions.
• Vague item descriptions on CN22/CN23 — biggest single cause of postal customs holds.
• Lithium batteries in checked baggage (must be in carry-on) or above the watt-hour limit without airline approval.
• Missing required certificates (phytosanitary, veterinary, CITES, prescription, product compliance).

Always verify against the destination's customs authority before acting. Not legal advice.
