As a customs entry writer, your primary responsibilities are to review import and export documents, ensure that all customs invoices and shipment papers are present, and prepare paperwork for clearance. You use specialized software to track inventory, apply for drawbacks and refunds, sign documents, organize customs rejections, answer client questions, complete clerical duties, and monitor the processing for goods going through customs. Because of this, you need basic computer skills. You may also plan shipment routes, check for hazardous qualifications, review transit time, security, and cost, and arrange a booking with carriers and customers.
