The global eCommerce market is experiencing significant growth. According to data from Statista, a leading data platform, the global B2C cross-border eCommerce market is projected to reach $7.9 trillion by 2030. As eCommerce businesses expand internationally, cross-border logistics has become an increasingly crucial aspect of operations. However, shipping special or potentially hazardous items such as lithium batteries, liquids, and cosmetics internationally often presents challenges and uncertainties. In this edition of e+Solutions eCommerce Logistics Classroom, we will share the international shipping considerations for these three product categories, aiming to assist eCommerce businesses in successfully navigating global deliveries.
Lithium Batteries
Lithium batteries are widely utilized in various electronic devices, including tablets, smartphones, facial cleansing devices, electric fans, and cameras. Due to their high flammability and sensitivity to environmental factors, which can potentially lead to fire hazards if damaged, the International Air Transport Association (IATA) classifies them as dangerous goods. It is important to note that Hong Kong Post regulations mandate the removal of detachable lithium batteries prior to mailing.
International Shipping Considerations:
When shipping products containing lithium metal batteries, eCommerce businesses should adhere to the following guidelines:
- Obtain comprehensive information about battery types and required documentation from suppliers, Providing the most recent Material Safety Data Sheet (MSDS) for products containing lithium batteries.
- Proactively consult with relevant shipping companies for specific protocols.
- Ensure proper packaging: Install batteries in devices and power off; Wrap devices in protective materials fill void spaces with cushioning and seal packages securely. Avoid wrapping lithium batteries in aluminum foil.
- Apply appropriate lithium battery labels to the package.

Liquids
Due to the potentially flammable nature of certain liquid products, they are subject to stringent regulations in international shipping. To ensure successful shipment, merchants must provide relevant documentation such as MSDS and clearly label ingredients and materials on the packaging. This facilitates customs identification and ensures compliance with import regulations of the destination country. Unidentifiable liquids are likely to be returned by customs authorities.
Products should be contained in original unopened containers with additional protection using plastic bags or sealed pouches to prevent leakage or contamination. eCommerce businesses should apply appropriate warning labels such as “Fragile” or “Flammable” based on product characteristics.
International Shipping Considerations:
While most liquid products can be shipped via standard air, ocean or land transport services, liquids containing alcohol or other flammable substances require special attention. eCommerce merchants should consult with shipping companies for specific guidelines and familiarize themselves with import/export restrictions of different countries. For instance:
- Alcoholic products must be packaged in wooden crates to ensure transport safety.
- Alcoholic beverages exported from Hong Kong must have an alcohol content below 30%.
- The UK imposes additional taxes on alcoholic beverages exceeding 35% alcohol content.
- Only 27 U.S. states permit the import of alcoholic products, each with varying restrictions.
For perishable liquid products, eCommerce merchants should employ appropriate temperature control methods such as dry ice or insulated packaging to maintain product integrity during transit.
Cosmetics
Cosmetics are common items for international shipping. Most cosmetic products can be delivered internationally through express courier services, including:
- Face masks: sheet masks, clay masks, gel masks
- Cream-based products: eyeliner gel, mascara, lipstick, eye shadow, eye pencils
- Gel-based products: foundation, essence, creams
International Shipping Considerations:
Certain cosmetic products require MSDS reports to comply with regulations, including:
- Products containing alcohol (e.g. makeup removers, toners, nail polish removers)
- Products containing medicinal ingredients (e.g. skincare products with steroids)
- Compressed aerosol products (e.g. sunscreen sprays, moisturizing sprays, compressed deodorants)
- Powder products (e.g. compact powders, blush)
- Oil-based products (e.g. nail polish)
Cosmetics are often packaged in glass containers or small boxes making them susceptible to damage during international shipping. To ensure safe delivery, eCommerce businesses should utilize individual sealed packaging and adequate cushioning materials.

In conclusion, as eCommerce businesses expand internationally, it is crucial to understand product characteristics and cross-border logistics complexities. When uncertain about product restrictions or flammability, proactively obtaining MSDS from suppliers is advisable. This documentation aids in understanding product properties and ensuring regulatory compliance. Given the varying requirements for imported products across different countries, including international shipping methods, declaration documents, customs clearance procedures and taxes, partnering with professional eCommerce logistics service providers like ePlus can streamline international order processing. This approach ensures successful product delivery while allowing eCommerce businesses to focus on core competencies such as marketing and business expansion, facilitating global market penetration.
