Packaging & Labeling Tips to Prevent Customs Rejections

Shipments are often stopped at customs not because of the product, but because of what’s on the outside the packaging and labels. A missing translation, the wrong symbol, or packaging that doesn’t meet regional rules can hold your cargo for weeks. The following guide outlines the mistakes that trigger rejections and the steps to make your shipments compliant the first time.

Why Packaging & Labeling Are a Customs Priority

Customs officers use packaging and labels as their first checkpoint. They need to verify origin, compliance marks, product type, and safety details before even opening the box. If anything looks incorrect or incomplete, your shipment can be flagged which means delays, penalties, or outright rejection.

The Most Common Labeling Errors

• No country of origin: Every shipment must clearly state “Made in [Country]”. Leaving this out is one of the fastest ways to get flagged.

• Language gaps: In the EU, labels must be in the official language(s) of the destination country. A label in English only won’t pass in France or Spain.

• Wrong or unauthorized compliance marks: CE, FCC, or FDA logos cannot appear unless you hold valid certification. Using them incorrectly is considered misrepresentation.

• Incomplete safety or product details: Missing ingredient lists (for food or cosmetics) or usage warnings (for electronics, chemicals, etc.) will trigger inspection.

Packaging Mistakes That Cause Rejections

• Non-compliant materials: Some countries ban certain plastics or non-recyclable packaging. The EU requires packaging to meet recyclability standards.

• Weak or damaged cartons: If goods arrive crushed or poorly packed, customs may classify them as “unfit” and block release.

• Missing recycling or eco-symbols: In markets with strict sustainability regulations, packaging must display correct recycling marks.

• False claims on the packaging: Terms like “organic” or “eco” without supporting certificates may cause goods to be held.

Regional Examples You Should Know

• European Union – CE marking where applicable, REACH compliance for chemical products, packaging recyclability, and mandatory multi-language labels.

• United States – FDA labeling for food, cosmetics, medical products; nutrition facts panels; UPC barcodes must be correct.

• China – Strict Chinese labeling laws for imports, including detailed product descriptions and importer details.

Costs of Getting It Wrong

Non-compliant packaging or labeling doesn’t just cause delays — it quickly turns into a chain of costs that eat into margins and weaken customer trust. Some of the most common consequences include:

Storage and demurrage charges
When customs flags a shipment, containers can sit at port yards or bonded warehouses for days or weeks. Each extra day means storage or demurrage fees, which often increase on a sliding scale. For high-volume shipments, this can add thousands of dollars in unexpected costs.

Repackaging and relabeling expenses
If packaging needs to be corrected at the destination, service providers charge a premium compared to fixing it at origin. Relabeling in bonded warehouses may involve breaking down pallets, reprinting compliant labels, and reassembling shipments, a costly and time-consuming process.

Regulatory fines and penalties
Customs agencies impose administrative fines for mislabeling, incorrect country-of-origin marks, or missing regulatory symbols. These penalties vary by country but can be substantial, particularly in industries like pharmaceuticals, electronics, or food.

Product return or destruction
In serious cases such as when packaging misleads consumers or violates safety laws authorities may order goods to be re-exported or destroyed. Both options are financially damaging, with little chance of recovering costs.

Pre-Shipment Checklist for Compliance

• Confirm the labeling requirements for the destination country.

• Translate labels into all required languages.

• Apply compliance marks only after certification is approved.

• Verify packaging materials meet local regulations.

• Ensure invoices, HS codes, and labels match exactly.

• Run a compliance audit with your freight forwarder before shipping.
