Navigating customs is often the most complex aspect of international parcel shipping. Missteps in documentation or classification can lead to delays, additional fees, or even seizure. Understanding key customs components helps you prepare shipments that sail smoothly through border controls.
- Harmonized System (HS) Codes
Customs officials use HS codes—a standardized global classification of goods—to determine duties and taxes. Accurately identify the six- to ten-digit code for each item. Incorrect HS codes can trigger audits, fines, or costly reclassification delays. - Commercial Invoice and Declaration Forms
For most international shipments, you must complete a commercial invoice detailing item descriptions, quantities, unit values, total value, and country of origin. Attach this and any CN22 or CN23 customs declaration forms on the outside of your package in a clear pouch. Some carriers integrate electronic data interchange (EDI) to submit paperwork digitally. - Duties, Taxes, and Incoterms
Know whether you ship under DDP (Delivered Duty Paid) or DDU (Delivered Duty Unpaid) terms. Under DDP, you cover all duties and taxes—your customer receives the parcel with no extra cost at delivery. With DDU, recipients pay import fees on arrival, which can lead to refusals. Factor these costs into pricing or choose DDP for seamless customer experiences. - Prohibited and Restricted Items
Every destination country enforces its own list of banned or restricted goods—ranging from perishables, batteries, and cosmetics to controlled substances. Consulting official government resources or copyright advisories prevents shipment rejections or confiscations. - Use a Customs Broker or Third-Party
For high volumes or complex shipments (e.g., medical devices), engaging a customs broker streamlines clearance. Brokers handle paperwork, payment of duties, and communication with customs authorities, reducing your administrative burden.
By mastering HS codes, accurate invoicing, Incoterms selection, and awareness of import regulations, you’ll minimize friction at the border and expedite international parcel shipping for your customers or personal recipients.
