Customs Duty Refund Recover What You Overpaid with AI

A customs duty refund is a reimbursement of import tariffs paid to U.S. Customs and Border Protection. The primary legal mechanism is duty drawback — a U.S. government program that allows importers to recover up to 99% of duties paid when imported goods are subsequently exported, used in manufacturing for export, or destroyed. Companies importing raw materials, retailers re-exporting inventory, and businesses receiving returned goods may all qualify. An estimated 80% of eligible refunds go unclaimed annually.

Duty drawback allows importers to file a claim with CBP demonstrating that imported goods (or substitutes) were exported, used in a manufactured export product, or destroyed. CBP reviews the claim, verifies the import-export link, and issues a refund of up to 99% of the original duties paid. There are four main drawback types: manufacturing, unused merchandise, rejected merchandise, and destroyed goods. Each has specific eligibility criteria and documentation requirements.

With traditional drawback providers using manual workflows, processing typically takes 9–12 months from document submission to refund receipt. Zollback's automated platform compresses this to 10–15 working days by using AI to parse documents and proprietary algorithms to compute optimal matching — eliminating the manual work that creates delays.

Required documentation typically includes import entry summaries, commercial invoices, bills of lading, proof of export (export declarations or bills of lading for outbound shipments), and manufacturing records if applicable. HTS code accuracy is critical — misclassifications can reduce or disqualify refunds. Zollback's AI automatically parses all of these document types from PDF, CSV, or ERP exports.

Yes. IEEPA tariffs paid on imported goods can be included in a duty drawback claim when those goods are subsequently exported, used in manufacturing for export, or destroyed. Duty drawback applies to most import tariffs, including Section 301, IEEPA, and standard ad valorem duties. Zollback's eligibility assessment identifies which of your import transactions qualify across all applicable tariff types.

The duty drawback process is complex — it requires matching import and export records across HTS classifications, accounting methods, and regulatory time limits, then filing structured claims with CBP via certified software. Most companies lack in-house expertise, and legacy providers historically served only large enterprises. Automated platforms like Zollback have made drawback accessible to companies of all sizes by eliminating the manual overhead that made it prohibitively costly for smaller importers.
