Customs hold IT shipments: 7 simple fixes to prevent delays

When customs hold IT shipments, the cost is rarely the storage bill. It is the data centre migration that cannot start, the refresh that slips a quarter, or the outage while an emergency spare part sits in a shed. Many avoidable holds start with incomplete documents, a classification question or a missing approval, and most of that can be settled before the goods leave.

The short version. Get the hold reason in writing first. Send a complete invoice and packing list, not a corrected line. Back up HS codes, ECCN status and battery safety with documents. Ask whether release against payment or a guarantee is available while the query runs, bearing in mind that customs can still detain goods for an inspection, a licence or an approval. Prevent the next hold with a pre-shipment check and a verified importer of record.

Carra Globe provides importer of record, exporter of record, delivered duty paid and freight forwarding services, so we have a commercial interest in your answer. What follows is written to be usable whether or not you ever speak to us.

This guide is for logistics and procurement teams, IT operations and anyone waiting on hardware at a border. It covers why holds happen, seven fixes to get goods released, and how to stop the next one. If you have no entity in the destination, our importer of record services can take the import on for you.

Why customs hold IT shipments

• Missing or vague documents. No unit values or currency, an incomplete consignee address, no Incoterm, no serial numbers where the destination or product calls for them, or a description as loose as “IT parts”.
• The wrong importer details. No importer named, a wrong EORI, EIN or VAT number, or a consignee not entitled to import. See importer of record versus consignee.
• HS code errors. Parts declared as finished systems, refurbished units declared as new, or embedded batteries overlooked. See the cost of incorrect HS codes.
• Encryption and export control questions. Customs or the exporter’s authority wants the ECCN or a vendor classification letter, and some destinations add their own encryption import rules.
• Missing approvals. Radio modules, telecom gear and some encryption products can need a type approval, licence or safety certificate in the destination.
• Valuation queries. Unexplained discounts, zero-value lines or related-party prices.
• Screening and inspection. Lithium batteries, transmitters and denied-party matches trigger checks, and electronics are often picked for X-ray or opening.

What to do in the first 24 hours

Work in parallel, not in sequence. Contact the importer of record first, then the broker or declarant who lodged the entry. Their legal duties differ by country and procedure, and the party who approves a correction is not always the one who files it, so settle both on the first call. Our note on what an importer of record does sets out the importer’s side. Ask the broker for the hold reference and the code customs gave, and ask the carrier or terminal where the goods are stored and what storage costs per day.

Ask every party the same five questions. What is the hold reason? What documents are wanted? Is an inspection booked, and when? What is the deadline to respond? Can the goods be released against payment or a guarantee while the query is open?

7 simple fixes to get IT equipment released

Fix 1: Get the hold reason in writing

Everything else depends on it. A verbal “they want more documents” sends teams chasing the wrong paperwork. Get the reference and the reason from the broker in an email, and keep one person as the single point of contact with customs.

Fix 2: Send a complete invoice and packing list

The commercial invoice is the main valuation document. Exact requirements depend on the destination and the entry procedure. Expect to need the invoice number and date, the seller, buyer and importer with full legal names, a clear description of each line, quantities, unit and total values and the currency. Add tax IDs, HS codes, origin, the Incoterm and payment terms wherever they apply, and check the local list with your broker before dispatch.

The packing list should map crate numbers to invoice lines, with quantities per box, gross and net weights and pallet dimensions. Serial numbers are not required everywhere, but listing them makes identification, licensing checks and inspection easier. Any mismatch between the two documents can prompt further questions or a physical examination. Our guide to documentation errors that trigger customs audits lists the usual ones.

Fix 3: Correct the HS code with evidence

Servers are commonly classified within heading 8471, and routers and switches often fall within heading 8517, but a heading is a starting point, not a final code. The full national code turns on the exact model, its function and the destination’s tariff. Your broker can usually lodge an amendment. Back it with spec sheets, model numbers, photos and a one-page classification note, and for repeat shipments consider a binding ruling where one is available. If the error started on the invoice, see what to do about a wrong HS code on an invoice, or check a code with our HS code finder.

Fix 4: Supply the ECCN or encryption statement

Tariff classification and export control classification answer different questions, so keep them as separate records. The HS code drives duty and other import measures. The ECCN is a US export control classification, and whether an export authorisation was needed also depends on the destination, the end user and the end use.

Ask the manufacturer for the classification and supporting data for the exact model. Encryption is often why networking and security products need one, and the answer might be 5A002 or 5A992.c, though neither fits every encrypted device. A vendor letter supports the review but does not guarantee release, and it does not replace the destination’s own import licence or type approval. BIS explains the categories in its encryption controls guidance, and our guide to ITAR and EAR compliance for IT hardware goes further.

Fix 5: Prove battery and radio compliance

For laptops, UPS units and anything else with lithium cells, check the dangerous-goods transport rules and get the manufacturer’s UN 38.3 test summary where they call for it. Whether customs also asks for it depends on the shipment and the destination, so keep it apart from electrical safety and radio evidence. Radio and telecom equipment may need conformity evidence or a type approval in the destination, and some markets want it before import rather than after. See the HS code for lithium batteries for how batteries are declared, and our guide to lithium battery customs clearance for the shipping side.

Fix 6: Make the inspection easy

Customs may X-ray, open crates, check serial numbers against the invoice or ask for devices to be powered on. Where customs permits it and a suitable facility is available, ask for the examination to take place at a bonded warehouse to limit storage costs. If functional testing is requested, offer a technical contact who can start the equipment safely. Clear asset tags and start-up notes speed it up. As a data security precaution, wipe customer data with a recognised sanitisation method before shipping and keep the certificate.

Fix 7: Check the release options and the route to challenge

Ask whether the goods can move while the question is settled. Under the EU’s current Union Customs Code, release generally depends on the duty being paid or a guarantee provided, though goods can still be held for an inspection, a licence or a restriction. A recast code, covered in our guide to the 2027 Union Customs Code changes, comes in by phases, so check which rules cover your procedure on the date of import.

In the United States, some entry procedures allow release before the entry summary is filed. Under 19 CFR 142.12 the entry summary and estimated duties are then generally due within 10 working days of entry. That is a filing deadline, not a release timeframe, so confirm the procedure with your broker and get any release in writing.

If you disagree with a decision, first establish which route applies. A release hold, a classification or valuation dispute and a challenge after liquidation each have their own route and deadline. In the US, a protest, usually on CBP Form 19, is generally due within 180 days of liquidation, or of the decision itself where there is none, as with an exclusion. In the EU, both depend on the decision and the member state. Your evidence pack is the invoice, the classification note and the export documents.

Detained goods in the US can have a separate route. For some detentions, if CBP makes no final admissibility decision within 30 days of the goods being presented for examination, the law treats that as an exclusion that can be protested. This does not apply where another agency decides admissibility or the law allows longer, so have your broker confirm it fits your hold.

Release request email. Use the subject line “Urgent release request, shipment [AWB or BL] held at [port]” and a body along these lines. “Shipment [ID] is held under [hold code]. Attached are the corrected commercial invoice, packing list, ECCN letter and UN 38.3 summary where relevant. Please confirm the hold reference, anything still outstanding and the expected release time. We will follow up within 24 hours.” Sign off as the importer of record or its representative.

When to escalate

Escalate to a senior compliance lead, a customs consultant or legal counsel if there is no clear route to release after two to three working days, if the hold suggests a material misdeclaration, or if the goods are business critical. The two to three day trigger is our own working rule, not a customs deadline. Penalties for misclassification, undervaluation or false declarations vary by country and can exceed the duty that was short. For normal timings to compare against, see how long customs clearance takes. Our guide to a CBP customs audit shows how records are tested afterwards.

Three holds we have cleared

• Enterprise routers, held 5 days. Customs suspected controlled encryption and the shipment had no vendor classification letter. The supplier issued an ECCN statement with data sheets, the broker resubmitted with it, and the goods were released on day five. The cost was storage and an expedited courier. The lesson is to have the encryption classification on file before dispatch.
• Laptops, held 3 days. Held on two separate points, origin verification and lithium battery safety. The exporter obtained a chamber-issued certificate of origin for the origin query and the manufacturer’s UN 38.3 test reports for the batteries, and the importer paid the storage. The lesson is to have both ready before the goods leave, because each answers a different question.
• Refurbished servers, held 7 days. Declared as new although the units were refurbished, which put the accuracy of the declaration in question and led to further regulatory checks, including on producer registration. Corrected classification details, the repair history and, for that check, WEEE registration evidence were submitted, and a minor penalty was paid. WEEE evidence mattered in this case, but it is a producer obligation, not a standard customs release document. The lesson is to declare condition accurately and keep repair and refurbishment records.

For servers specifically, see our guide to a customs hold on servers.

How to stop the next hold

• A pre-shipment check. A fixed invoice template, a packing list with serial numbers where needed, HS and ECCN confirmed per model, battery documents, origin evidence and denied-party screening, all before the goods leave.
• The right importer and broker. Confirm who is named as importer, which registrations it holds and that the broker has a valid customs power of attorney. Vet customs brokers with IT hardware experience on response times for holds.
• Pre-arrival filing. File before arrival where the destination permits or requires it, use binding rulings where they exist, and use trusted trader status such as AEO or CTPAT where you hold it. Those programmes can speed processing but do not exempt goods from holds or inspection.
• Supplier controls. Train suppliers on the invoice fields that matter and reject documents that leave them blank. Our import and export documentation services can take this on.

How Carra Globe handles customs holds

As importer of record, we deal with the customs authority directly and work the hold rather than passing it back to you. For equipment going back out, our exporter of record service covers the export side. Most of the holds we see trace back to classification, valuation or a missing approval, which is why we settle those before dispatch.

Carra Globe works through importer-side registrations and local importing structures appropriate to the goods and destinations it accepts, its own in some markets and established local structures in others. Approvals falling outside the available structure are flagged before a delivery date is agreed. For full rollouts, see our data center solutions or avoiding customs delays with IOR services. Send the hold notice, invoice and packing list to info@carraglobe.com and we will tell you what customs is asking for.

Frequently asked questions

Why is my IT shipment stuck in customs?

Usually because of an incomplete invoice or packing list, a wrong HS code, a problem with the importer details, or a battery, radio or encryption question. The broker can give you the exact hold reason.

How do I get a shipment released from customs?

Get the hold reason in writing, send the corrected documents, supply any classification or safety evidence requested, pay or secure the duty where release is available on that basis, and support any inspection.

How long does a customs hold usually last?

It depends on the reason and the country. A document query can clear in days once the right papers arrive, while an inspection or approval issue can take much longer.

What documents do I need to import electronics?

A commercial invoice, packing list and transport document, the importer’s tax or EORI number, HS codes per line, and where relevant an ECCN letter, UN 38.3 battery summary and certificate of origin.

Who pays storage while goods are held?

Usually the importer or the party that agreed to pay under the Incoterm and contract. Storage and demurrage keep running during the hold, so speed matters.

Can I appeal a customs decision on my IT equipment?

Usually, but the route depends on the decision. A US protest is generally due within 180 days of liquidation, or of the decision where none applies. EU time limits vary by member state.
