Outbound cargo wood packaging removal treatment method

First, heat treatment (HT)

1. It must be ensured that the wood core temperature reaches at least 56°C for more than 30 minutes.

2. Kiln drying (KD), chemical pressure infiltration (CPI) or other treatment methods can be regarded as heat treatment as long as they meet the heat treatment requirements. Such as chemical pressure soaking can be achieved through steam, hot water or dry heat and other technical indicators required for heat treatment.

Second, methyl bromide fumigation treatment (MB)

1. Under normal pressure, it is treated according to the following standards

Temperature dose

(g/m3) minimum concentration requirement (g/m3)

0.5 hours 2 hours 4 hours 16 hours

≥21°C 48 36 24 17 14

≥16°C 56 42 28 20 17

≥11°C 64 48 32 22 19

2. The minimum fumigation temperature should not be lower than 10 °C, and the minimum fumigation time should not be less than 16 hours.

Third, the international standards for plant quarantine measures or other country-by-region accreditation of other methods of harm removal.
