Companies with chemicals that will be exported via ocean freight must also comply with British Standard BS5609. This is a requirement for International Maritime Dangerous Goods (IMDG) certification
BS5609 Section 2 requires that the blank label and adhesive can withstand a three-month saltwater submersion test. It also includes artificial weathering tests (salt spray and sunlight). When a label is Section 2 certified, it means the blank label is BS5609 Section 2 compliant.
BS5609 Section 3 tests the printed label for abrasion resistance and permanence of print. This includes artificial weathering (salt spray & sunlight), tape removal and abrasion resistance. This test is conducted on labels printed with specific printers.
Even if you are not shipping overseas, going with a BS5609 certified material ensures a durable label that will resist falling off or fading if exposed to water or sunlight. Avery UltraDuty GHS Chemical Labels are BS5609 Section 2 and 3 certified.
