Moisture Resistance refers to the ability of a material or packaging to resist moisture penetration, absorption, or condensation in humid environments. It is a key quality indicator in foreign trade transportation and warehousing. Usage scenarios include: quality clauses in export contracts, packaging requirements, product specifications, inspection standards (such as ISO 2233, ASTM D2247), etc. Notes: 1) Moisture resistance is not equivalent to waterproofness; the former only resists moisture, while the latter can completely block liquid water; 2) Different modes of transportation (sea, air) have different moisture resistance requirements; sea freight requires stricter standards due to high humidity; 3) Test conditions (temperature, humidity, duration) must be specified to avoid disputes. It is often used interchangeably with 'moisture-proofness,' but moisture resistance emphasizes barrier capability under dynamic environments. Foreign trade practitioners should quantify indicators in contracts (e.g., moisture vapor transmission rate ≤5g/m²·24h) and specify the addition of desiccants or vacuum treatment inside packaging.
📝 Examples
1. The packaging of the goods under this contract must have excellent moisture resistance to ensure that internal humidity does not exceed 60%RH during container sea transportation; otherwise, the buyer has the right to reject the goods. (Note: Specify moisture resistance indicators in the contract as a basis for quality acceptance.)
2. The moisture resistance test report we provided shows that the batch of electronic products functions normally after being placed at 40°C and 90%RH for 72 hours, meeting your moisture resistance requirements. (Note: Use test data to prove that the product's moisture resistance meets standards, for customer communication or dispute resolution.)
💡 Foreign Trade Tips
Foreign trade terms are the foundation of international business communication
Trade practices may vary slightly by country; pay attention when using them
When using terms in contracts, specify the applicable version (e.g., Incoterms 2020)
