Your customer just messaged. Their package has been stuck at customs for nine days, and they want answers.
This moment—right here—determines whether they become a loyal repeat buyer or blast your brand on social media. International customs delays trip up even experienced ecommerce operators. The shipment tracking shows "held at customs," your customer expects immediate resolution, and you're caught in the middle with limited control over foreign border agencies.
Here's the reality: international shipping complications aren't going away. Cross-border ecommerce continues growing, and with that growth comes more customs inspections, more duty calculations, and more confused customers wondering why they owe money before receiving their purchase [1]. The operators who win don't eliminate these problems. They handle them with clear communication that sets accurate expectations from the start.
This guide gives you the exact email scripts, decision frameworks, and escalation boundaries your team needs to navigate international customs delays without burning hours or damaging customer relationships.
Why International Customs Delays and Duty Charges Create Support Chaos
International orders generate support tickets at roughly three times the rate of domestic shipments [2]. The reasons stack up quickly:
Hidden costs surprise customers. Many buyers don't realize they'll owe import duties and taxes until a courier demands payment before delivery. That unexpected charge—sometimes 20-30% of the order value—feels like bait-and-switch, even when your checkout page mentioned it.
Tracking goes dark. Once a package enters customs processing, standard tracking often stops updating. Days pass with no information. Customers assume the worst.
Resolution sits outside your control. Unlike a warehouse picking error or carrier misroute, you can't call customs and fix this. That powerlessness frustrates both your team and your customers.
Time zones compound confusion. Your customer in Australia emails at 3 AM your time, expecting the same-day response they'd get from a local retailer. Meanwhile, the customs office handling their package operates on yet another schedule.
The common mistake? Treating these tickets like standard "where's my order" inquiries. They're not. They require specific information, calibrated expectations, and clear boundaries about what you can and cannot do.
The Pre-Purchase Foundation: Setting Expectations Before Problems Start
The cheapest support ticket is the one you never receive. For international orders, that means building duty and customs information into your customer experience before checkout.
Product pages should mention potential import fees. A simple line works: "International orders may be subject to customs duties and local taxes upon delivery. These fees are determined by your country's customs authority and are the responsibility of the recipient."
Checkout confirmation needs explicit language. When someone completes an international purchase, your order confirmation email should include a dedicated section on customs expectations:
About International DeliveryYour order is shipping to [Country]. Depending on your local customs regulations, you may be required to pay import duties or taxes before your package is released for delivery. These charges are set by your government, not by us, and we cannot predict the exact amount.Most shipments clear customs within 3-7 business days, though some may take longer during peak periods or if additional documentation is required.
This isn't about covering yourself legally (though it helps). It's about preparing customers mentally. When they know duties might happen, the email from their courier asking for payment feels expected rather than shocking.
Core Email Scripts for Customs and Duty Situations
Every international support situation falls into a handful of categories. Having templated responses for each one ensures consistent communication while saving your team from rewriting similar emails dozens of times weekly.
Script 1: Package Held at Customs (No Additional Information Available)
Use when: Tracking shows customs processing, but you have no details on why or how long it will take.
Subject: Update on Your Order [#ORDER] – Currently in Customs Processing
Hi [First Name],
I checked on your order, and I can see it's currently being processed by customs in [Country].
Here's what that means: customs authorities review incoming international shipments to assess duties and verify contents. Most packages clear within 3-7 business days, though timing can vary based on their current volume and whether they need any additional documentation.
What happens next:
If duties or taxes apply, the courier will contact you directly with the amount and payment instructions before delivering your package
If customs needs additional information, they'll reach out to you or the courier—I'll flag this order so we can help if anything comes up
What you can do:
Keep an eye on emails from [Carrier Name], as they'll be your point of contact for any customs-related payments
Make sure your phone number is up to date with the courier in case they need to reach you
I know waiting is frustrating, especially when tracking isn't updating. I'll continue monitoring this on our end and reach out if I see any changes.
[Sign-off]
Why this works: It acknowledges the frustration, explains the process in plain terms, gives concrete next steps, and sets a realistic timeline without overpromising.
Script 2: Customer Asking "What Duties Will I Owe?"
Use when: A customer asks you to predict their customs charges before or after purchase.
Subject: Re: Import Duties Question for Your Order
Hi [First Name],
Great question—I wish I could give you an exact number, but duty amounts are calculated and collected by your country's customs authority, not by us. The amount depends on several factors we don't have visibility into:
Your country's tariff classification for the product type
Current duty rates (which can change)
Whether any trade agreements apply
The declared value and your country's de minimis threshold
For [Country], you can often estimate potential duties using [Country's customs website or a duty calculator if applicable]. The product category would be [general category, e.g., "apparel" or "electronics"].
I can tell you that your order has a declared value of [Order Total], which customs will use as their starting point.
If you'd like, I'm happy to provide a commercial invoice or any other documentation that might help speed up customs processing once your order ships.
[Sign-off]
Decision boundary: Never quote specific duty amounts. Even if you've seen similar orders charged a particular rate, customs assessments vary. Giving a number creates an expectation you can't guarantee.
Script 3: Customer Refuses to Pay Duties
Use when: A customer's package is held because they won't pay the assessed duties.
Subject: Re: Duties Required for Your Order [#ORDER]
Hi [First Name],
I understand—unexpected charges are frustrating, especially when you've already paid for your order.
Unfortunately, import duties and taxes are set and collected by [Country]'s customs authority, not by us. We have no ability to reduce, waive, or pay these fees on your behalf. They're essentially a tax your government charges on imported goods.
Your options at this point:
Pay the duties to receive your package. The courier will release your order once the customs charges are paid. This is the fastest path to getting your items.
Refuse delivery. If you choose not to pay, the package will eventually be returned to us. Once we receive and process the return, we can issue a refund for the product cost. Note that original shipping charges aren't refundable, and the return process typically takes 4-6 weeks for international packages.
Dispute the duty amount with customs. If you believe the assessment is incorrect, you can contact [Country]'s customs authority directly to request a review. The courier holding your package can usually provide the customs office contact information.
I genuinely wish I could do more here. Let me know which option works best for you, and I'll help however I can on our end.
[Sign-off]
Escalation boundary: This is a firm boundary. No matter how much a customer pushes, you cannot pay their customs duties or force customs to release a package. The email is empathetic but clear about what's possible.
Script 4: Extended Customs Delay (10+ Business Days)
Use when: A package has been in customs significantly longer than normal with no movement.
Subject: Extended Delay on Your Order [#ORDER] – Next Steps
Hi [First Name],
Your order has been in customs processing for longer than we typically see, and I want to make sure we're doing everything possible on our end.
What I've done so far:
Confirmed the package is still in customs (not lost or returned)
Verified all shipping documentation was submitted correctly
Flagged this with our carrier for priority follow-up
What might be happening:
Customs may be conducting a more detailed inspection of the shipment
There could be a backlog at the customs facility
They may need additional documentation (though we haven't received any request yet)
Recommended next step:At this point, contacting the carrier directly often helps move things along. Here's what you'll need:
Carrier: [Carrier Name]
Tracking number: [Tracking]
Carrier contact: [Phone/Email]
Your reference: Order [#ORDER]
Ask them for the customs broker contact or whether any action is required from you. Sometimes a direct inquiry from the recipient prompts faster processing.
If you reach a dead end or get information that I can help with, just reply here. I'm also happy to provide any additional commercial documentation if customs requests it.
[Sign-off]
Why direct customer contact helps: Customs authorities and their contracted brokers often respond faster to the actual importer of record (your customer) than to the shipper. This isn't passing the buck—it's directing them to the path most likely to get results.
Script 5: Customer Received Package But Is Charged Incorrectly
Use when: Customer believes they were overcharged on duties.
Subject: Re: Duty Charges on Your Order
Hi [First Name],
I'm sorry the duty charge seemed higher than expected. Let me help where I can.
What I can provide:
Commercial invoice showing the declared value ($[Amount])
Product descriptions and HS codes we used for customs documentation
Proof of what was actually in the shipment
What I can't do:
Refund duties (these were paid to your government, not to us)
Contact customs on your behalf to dispute the charge
Change customs classifications retroactively
If you believe the assessment was incorrect, the process is to file a dispute directly with [Country]'s customs authority. You'll typically need the documentation I mentioned above—just let me know and I'll send it over right away.
For reference, the declared value on your shipment was $[Amount], and the products were classified under [general category]. If customs used a different classification or assessed a higher value, that's usually where disputes arise.
Happy to help you gather whatever you need to pursue this.

Decision Framework: When to Escalate vs. Template
Not every international shipping issue deserves the same response. Here's how to triage:
Tier 1: Template Response (Handle Immediately)
Standard "where is my package" during normal customs timeframes
Pre-purchase duty questions
First contact about customs delay under 10 business days
Requests for shipping documentation
Required fields to check: Order number, tracking status, destination country, ship date.
Tier 2: Personalized Response (Investigate First)
Customs delays exceeding 10 business days
Customer claims customs is requesting documentation you haven't received notice of
High-value orders ($500+) in customs
Repeat customers experiencing issues
Required actions: Check carrier portal for detailed customs status, verify documentation was transmitted, escalate to carrier if needed before responding.
Tier 3: Escalate to Lead/Manager
Customs has seized or is threatening to destroy merchandise
Customer is a VIP or high-value account facing significant issues
Legal documentation requests (subpoenas, formal customs inquiries)
Situations requiring discretionary goodwill outside normal policy
Escalation trigger: If you're about to promise something outside standard policy, stop and escalate first.
Edge Cases That Require Special Handling
The Shipment Was Returned Without Customer Notification
Sometimes customs returns packages without the expected customer contact. When a shipment reappears at your warehouse:
Verify the return reason in carrier records (refused, documentation issue, prohibited item, etc.)
Contact customer before issuing any refund—they may want you to reship
If reshipping, determine what caused the return and whether it's fixable (better documentation, different carrier, etc.)
Document the full timeline for your records
Prohibited or Restricted Items
If customs holds a package because your product is restricted in the destination country:
Do say: "Unfortunately, [Country] restricts the import of [product category]. This isn't something we can override—it's a regulatory decision by that country's government."
Don't say: "We didn't know this was restricted." (You should have caught this before shipping.)
Resolution path: Offer a full refund once the item is returned, or if the customer has a forwarding address in a country where the item is permitted, discuss alternatives.
Customer Wants You to Misrepresent Value on Customs Forms
This request comes up regularly: "Can you mark it as a gift?" or "Can you put a lower value?"
The only appropriate response: No.
Falsifying customs documents is illegal, exposes your business to serious penalties, and can result in shipments being seized. Your template:
"I understand you're trying to minimize duty charges, but we're required to declare accurate values on customs documentation. Falsifying these forms is considered customs fraud and can result in fines, seizure of goods, and being flagged for enhanced inspection on future imports. I'm not able to alter the declared value. If you'd like to proceed with accurate documentation, I'm happy to help with your order."
Building This Into Your Team's Workflow
For Teams of 1-3 People
Keep these scripts in a shared document or your help desk's template library. Create a simple tagging system so you can quickly identify international shipping tickets (most help desks let you auto-tag based on shipping address or keywords).
Set a daily or twice-daily check of any international orders showing unusual tracking patterns. Five minutes of proactive monitoring prevents hour-long reactive firefights.
For Teams Using Outsourced Support
If you're working with a support partner like Evergreen Support, these scripts and escalation boundaries should be part of your onboarding documentation. The clearer your decision rules, the faster your team can resolve issues without constant check-ins.
Specifically, define:
Which goodwill offers (if any) agents can make for customs-related frustrations
At what order value or delay length tickets should be escalated
What documentation agents have access to generate themselves vs. request from you
Measuring What Matters
Once you've implemented these processes, track:
First-response resolution rate for customs inquiries. What percentage are resolved with one reply? If it's below 60%, your templates may need more complete information.
Time-to-first-response for international shipping tickets. These customers are already anxious—speed matters.
Escalation rate from Tier 1 to Tier 2+. If most tickets escalate, your templates aren't comprehensive enough. If almost none escalate, make sure your team isn't over-templating situations that need personal attention.
Repeat contact rate. Are customers coming back two or three times about the same customs issue? That suggests your initial response isn't setting clear enough expectations.
The Bottom Line
International customs delays aren't fully in your control, but how you communicate about them absolutely is. The operators who handle these situations well share a few traits:
They set expectations before problems occur
They respond quickly with accurate information
They're honest about what they can and cannot do
They give customers clear next steps rather than vague reassurances
These scripts won't make customs processing faster. What they will do is transform frustrated customers into people who feel informed and supported—even when the news isn't what they wanted to hear.
The goal isn't zero complaints about international shipping. It's building a support operation that handles those complaints efficiently without your team reinventing responses for every ticket or promising things you can't deliver.

Frequently Asked Questions
How long does customs processing usually take?
Most international shipments clear customs within 3-7 business days. However, timing varies significantly by country, product type, and current inspection volumes. Peak shopping seasons and periods of regulatory change can extend this considerably.
Can I pay my customer's import duties for them?
While you could theoretically build duty costs into your pricing and use a delivery-duty-paid shipping method, you cannot pay duties retroactively on a shipment already assessed by customs. Those charges are owed by the importer of record—your customer.
Should I use DDP (Delivered Duty Paid) shipping?
DDP shipping means you collect duties at checkout and handle payment on the customer's behalf. It creates a cleaner customer experience but requires accurate duty estimation, adds complexity to your fulfillment, and means you absorb any assessment differences. For high-volume international sellers, it's often worth the investment. For occasional international orders, the administrative burden usually outweighs the benefits.
What do I do if a customer threatens a chargeback over duties?
Duties are charged by a government entity, not by your company. Document your pre-purchase disclosures and order confirmation language. In a chargeback dispute, evidence that the customer was informed duties might apply typically supports your case. However, chargebacks are often decided in the customer's favor regardless—weigh whether fighting the chargeback is worth the time versus issuing a partial goodwill credit to preserve the relationship.
How can I reduce the number of support tickets about international shipping?
Build comprehensive international shipping FAQs, add duty disclaimers to product pages and checkout, send proactive emails when tracking shows customs processing, and consider offering package tracking that provides more granular customs updates. The more you communicate proactively, the less customers need to contact you reactively.
