Procedures for Assessing the Impact of New Customs Rules
Logistics teams should begin by examining their main import/export items' HS Codes in relation to the new decree's wording. This determines if there are changes to duty rates or classification criteria. If adjustments are found, coordinate with foreign suppliers to ensure that commercial invoices and packing lists reflect the correct descriptions and codes.
Proactive Supply Chain Risk Control
Using a pre-departure checklist prevents port delays and customs holds that stem from filing errors under the new regulations. Aligning internal SOPs with the new rules ensures cargo flows smoothly and logistics costs remain within budget.
