Frequently Asked Questions (FAQ)
Q1: Which testing standards apply to my product?
Applicable standards depend on: product category (electronics, toys, food contact), target market (US, EU, China), and product-specific regulations. Your Shenzhen trading company identifies applicable standards.
Q2: Can I use different standards for different markets?
Yes. Products sold in multiple markets may need to comply with different standards. Your trading company manages testing to multiple standards. The most efficient approach is testing to the strictest standard, which often satisfies multiple markets.
Q3: How do I verify that a testing laboratory is accredited?
Check the laboratory’s accreditation certificate: ISO 17025 accreditation from a recognized accrediting body. Verify accreditation scope covers your specific tests. Check expiration date. Your trading company uses accredited laboratories.
Q4: What if a product passes one standard but fails another?
This can happen when standards have different requirements. You need to meet the standards for your target markets. If a product fails a standard for a specific market, it cannot be sold in that market unless modified to comply.
Q5: How often are testing standards updated?
Standards are reviewed and updated periodically (typically every 3-10 years). Some are updated more frequently. Your trading company monitors standard updates and advises when changes affect your products.
