International shipping can be a complicated process, especially when it comes to restricted items like powders and liquids. Many courier services refuse to transport these items due to safety, regulatory, and logistical concerns. In this article, we’ll explore the main reasons behind these restrictions and offer some solutions for shipping such items legally and safely.
1. Safety Concerns
Flammability and Explosiveness
Some powders and liquids are flammable, corrosive, or even explosive. Changes in air pressure and temperature during air transport can increase the risk of leaks, combustion, or chemical reactions. Items such as perfumes, alcohol-based products, and chemical reagents are particularly dangerous in transit.
Unidentified Substances
Powders, in particular, can be mistaken for illegal substances, explosives, or hazardous chemicals. If a package is suspected of containing a prohibited or dangerous substance, it may be seized, destroyed, or lead to further legal complications.
2. Customs and Regulatory Restrictions
Strict Airline and Transport Regulations
International Air Transport Association (IATA) regulations impose strict rules on shipping hazardous goods. Many airlines refuse to transport unidentified powders or liquids due to safety concerns, making it difficult for couriers to accept them.
Customs Clearance Challenges
Each country has different regulations regarding the import and export of liquids and powders. Customs authorities may require additional testing, documentation, or even prohibit the entry of certain substances, leading to delays or rejections.
Banned or Controlled Substances
Some powders and liquids contain ingredients that are controlled or banned in certain countries. For example, pharmaceutical ingredients, chemical solutions, and biological substances often require special permits or may be completely prohibited from importation.
3. Risk of Leakage, Contamination, and Deterioration
Leakage Risks
Liquids can leak during transit due to pressure changes, temperature fluctuations, or improper packaging. A spilled liquid could damage other packages or even the transport vehicle.
Powder Spillage and Misidentification
Unsealed or improperly packed powders may spill during transit, contaminating other shipments. Spilled powders may also trigger security alarms, leading to shipment delays or confiscation.
Degradation of Perishable Items
Food-grade powders and liquid products may deteriorate during transit due to temperature changes, humidity, or prolonged shipping times, affecting their safety and quality.
