Taiwan Toxic Chemical Import Permit 2026

When Taiwan import rules list 553 or 550, approval from the Ministry of Environment is required before customs declaration.

Short answer: what is needed for toxic chemical imports?

If import rules list 553 for toxic chemicals or 550 for concerned chemicals, obtain a permit or approval from Taiwan Ministry of Environment. Confirm control status, file through FLORA, prepare SDS and disaster prevention data, then attach approval for customs. If concentration is below control thresholds, a 533/553 review number may apply.
