TL;DR – Quick Declaration Cheat Sheet

Here is what you need to declare for the most common destinations:

The golden rule: Declare at a value that is believable for the weight and type of items in your package. Not too low, not too high.

What Is a Customs Declaration and Why It Matters

Every international package requires a customs declaration form attached to the outside. This form tells the customs authority of the destination country what is inside the package and how much it is worth.

Customs officers use this information to decide:

1. Whether to charge import duties and taxes — Most countries charge VAT/GST and import duties above a certain value threshold
2. Whether to inspect the package — Suspicious declarations trigger physical inspections
3. Whether to seize the package — Clearly fraudulent declarations or prohibited items lead to seizure

When you submit a shipping parcel through your agent, they ask you for two things: the declared value and the item description. These go on the customs form. Getting them right is one of the most important steps in the whole process.

If you are using ACBuy, you will fill in the declaration when submitting your parcel. Our ACBuy Customs Guide walks through this step by step with screenshots.

How Customs Officers Decide What to Inspect

Understanding how customs works helps you make better declaration decisions. Here is how a typical customs facility processes incoming packages:

Automated Screening

Every package goes through X-ray scanning and automated risk assessment. The system flags packages based on:

• Weight vs declared value — A 10kg package declared at $5 is an obvious red flag
• Origin country — Packages from China get more scrutiny than packages from Japan or South Korea
• Shipping line — Commercial carriers like DHL clear their own customs and inspect more; postal services like EMS rely on national customs
• Description — Vague descriptions like "gift" or "personal items" raise suspicion
• Historical data — If your address has received many flagged packages before, new ones get extra attention

Manual Inspection

Packages flagged by the automated system go to a customs officer who may:

• Check the declaration against the X-ray image
• Open and physically inspect the contents
• Compare items to known brands for counterfeiting
• Request additional documentation from the recipient

What Triggers Seizure

Seizure is the worst-case scenario. It typically happens when:

• The declaration is blatantly fraudulent (declaring $3 for a 15kg package)
• Items are clearly identifiable as counterfeit with prominent brand logos visible
• The package contains restricted or prohibited items
• The recipient has a history of seized packages at the same address

Country-by-Country Declaration Guide

United States — The Most Lenient

The USA has an incredibly generous $800 de minimis threshold. This means packages valued under $800 enter duty-free with minimal inspection.

How to declare for USA:

• Declare at $10-14 per kg
• A 5kg haul: declare at $50-70
• A 10kg haul: declare at $100-140
• Keep total under $800 (which should not be hard for personal hauls)

Item descriptions: Use generic but accurate terms:

• "Cotton t-shirts" instead of just "clothing"
• "Athletic shoes" instead of "sneakers" or brand names
• "Textile jacket" instead of "hoodie"

Risk level: Low. US customs rarely inspects personal fashion shipments under the $800 threshold.

United Kingdom — Post-Brexit Rules

Since Brexit, the UK has its own import rules separate from the EU. The threshold for online purchases is 135 GBP, above which VAT is charged.

How to declare for UK:

• Declare at $8-12 per kg
• A 5kg haul: declare at $40-60
• Keep total under 135 GBP (approximately $170)
• If using UK Tax-Free shipping lines, VAT is pre-paid so declare normally

Item descriptions: Be specific but not branded:

• "Men's cotton jumper" (UK English)
• "Women's canvas trainers"
• "Polyester sports jacket"

Risk level: Medium. Royal Mail handles most EMS deliveries and customs is moderate. Tax-free lines are recommended for larger hauls.

Germany — Strictest in Europe

German customs (Zoll) is legendary for its thoroughness. Since the EU removed the 22 EUR duty-free threshold in 2021, every package is subject to VAT.

How to declare for Germany:

• If using tax-free lines: declaration matters less as taxes are pre-paid
• If using EMS/DHL: declare at $5-8 per kg
• A 5kg haul via EMS: declare at $25-40
• Keep declarations low but believable

Item descriptions: German customs pays attention. Use:

• "Baumwoll T-shirts" or "cotton t-shirts"
• "Sportschuhe" or "sports shoes"
• Never use brand names

Risk level: High for non-tax-free lines. We strongly recommend using EU Tax-Free or Tariffless for Germany. See our ACBuy Shipping Guide Europe for more on this.

France — Increasingly Strict

French customs has tightened enforcement significantly since 2024. Similar to Germany, there is no duty-free threshold for most imports.

How to declare for France:

• Tax-free lines recommended
• If using EMS: declare at $5-8 per kg
• A 5kg haul: declare at $25-40

Risk level: Medium-High. Tax-free lines dramatically reduce risk.

Canada — Low Threshold, Moderate Enforcement

Canada has a surprisingly low duty-free threshold of just 20 CAD (about $15 USD). However, enforcement is moderate and packages under this threshold often pass through without issues.

How to declare for Canada:

• Declare at $10-12 per kg
• A 5kg haul: declare at $50-60
• Be prepared to pay duties — most hauls will exceed the 20 CAD threshold
• Canada Border Services Agency (CBSA) charges duties + GST/HST on declared value

Risk level: Medium. Expect to pay duties on most shipments, but seizure risk is low.

Australia — Very Generous Threshold

Australia has a 1000 AUD duty-free threshold (about $650 USD), making it one of the most lenient countries for imports.

How to declare for Australia:

• Declare at $12-15 per kg
• A 5kg haul: declare at $60-75
• Keep total under 1000 AUD

Risk level: Low. Australian Border Force is more focused on biosecurity than fashion items. Declare reasonably and you will be fine.

Netherlands and Belgium — High Risk Hubs

Both countries house major European logistics hubs. DHL's European hub is in the Netherlands, and Belgium handles significant cargo volume. This means more customs infrastructure and more inspections.

How to declare:

• Use tax-free lines exclusively
• If using EMS: declare at $5-7 per kg
• Keep packages small (under 4kg)

Risk level: High for non-tax-free lines. These are the highest-seizure-rate countries in Europe.

Spain, Portugal, and Italy — Moderate

Southern European countries tend to have more relaxed customs enforcement, though this has been tightening.

How to declare:

• Declare at $8-10 per kg
• A 5kg haul: declare at $40-50
• Tax-free lines recommended but EMS works reasonably well

Risk level: Low to Medium.

Scandinavia (Sweden, Denmark, Finland, Norway)

EU member Scandinavian countries follow EU rules. Norway, being outside the EU, has its own import rules with a low threshold.

How to declare:

• Sweden, Denmark, Finland: same as EU, use tax-free lines, declare $5-8/kg
• Norway: 350 NOK threshold (about $35 USD), declare at $8-10/kg

Risk level: Medium for EU members, Low-Medium for Norway.

The Art of Writing Item Descriptions

The item description on your customs form is almost as important as the declared value. Here is how to write descriptions that pass customs without raising flags:

Do

• Be specific about the material: "cotton t-shirt," "polyester jacket," "leather belt"
• Use generic product names: "athletic shoes," "casual trousers," "knit sweater"
• List items separately if your agent supports it: "2x cotton t-shirts, 1x sports shoes"
• Match the number of items to the package weight (4 cotton t-shirts at $5 each = $20 for about 800g makes sense)

Do Not

• Use brand names ever — not Nike, not Adidas, not anything
• Write "gift" as the description — this is a huge red flag
• Write "personal items" or "samples" — equally suspicious
• Use vague descriptions like "goods" or "stuff"
• Describe items as "shoes" when the package weighs 200g (obviously not shoes)

Shipping Insurance: When to Buy It

Most agents offer shipping insurance that covers lost or seized packages. Here is when it is worth the cost:

Always Buy Insurance When

• Your haul is worth more than $100
• You are shipping to a strict customs country (Germany, Netherlands, Belgium)
• You are using a shipping line with higher customs risk (DHL, UPS, FedEx)
• It is your first haul and you are not sure about the process

Insurance Is Optional When

• Your haul is under $50 total value
• You are shipping to a lenient country (USA, Australia)
• You are using tax-free shipping lines
• You have shipped successfully to your address before

How Agent Insurance Works

1. When submitting your parcel, check the "shipping insurance" option
2. Pay an additional 3-5% of declared value
3. If your package is seized by customs, provide evidence (tracking showing seizure, customs letter)
4. Agent refunds the value of your items (not shipping cost in most cases)
5. Processing time is typically 2-4 weeks

Note: Insurance covers customs seizure and lost packages. It does not cover items damaged during shipping (though agents handle damage claims separately through the carrier).

What to Do If Customs Contacts You

If your local customs office contacts you about a package, do not panic. Here is the step-by-step process:

If They Ask for an Invoice

1. Contact your agent and request a commercial invoice matching your declaration
2. Most agents (including ACBuy) can generate these automatically
3. Submit the invoice to customs within the deadline they specify
4. In most cases, they will release the package after receiving the invoice

If They Ask for Proof of Payment

1. Screenshot the transaction from your agent showing the amount paid
2. If using PayPal, provide the PayPal transaction receipt
3. Make sure the amount matches or is close to your declared value

If They Assess Duties

1. You can usually pay the duties and receive your package
2. The duty amount is based on your declared value plus any VAT/GST
3. It is often cheaper to just pay the duties than to refuse the package

If They Seize the Package

1. You will receive an official seizure notice
2. You can contest the seizure (rarely successful for replica items)
3. File an insurance claim with your agent
4. Use a different shipping address for future orders (customs may flag repeat addresses)

Common Declaration Mistakes That Lead to Seizures

Learning from others' mistakes can save you. Here are the most common declaration errors:

1. Declaring $1-5 for a 5kg+ package — The most common mistake. No legitimate package of clothing weighing 5kg costs $3. This is the number one trigger for inspections.

2. Using brand names in the description — Writing "Nike Air Jordan" on a customs form is practically begging for a seizure. Use generic descriptions always.

3. Over-declaring — Some people think declaring a high value looks more legitimate. It does not. It just means you pay more duties if assessed. Declare at the sweet spot for your country.

4. Shipping too much to one address too frequently — If you receive packages from China every week, your address may get flagged. Space out your orders by at least 2-3 weeks.

5. Putting all items in one massive package — A 15kg package from China is unusual for personal use. Split large hauls into packages of 5-8kg maximum.

6. Ignoring the description field — Some people leave it blank or write one word. A proper, specific description shows legitimacy.

Advanced Declaration Strategies

For experienced buyers looking to minimize customs risk further:

Split Shipping by Item Type

Instead of mixing shoes, clothing, and accessories in one package, ship similar items together. A package of "3 cotton t-shirts and 2 shorts" is more believable than "1 shoe, 1 jacket, 1 belt, 1 hat, 1 t-shirt."

Vary Your Shipping Address

If you live in an apartment building or have access to multiple addresses (office, family), rotate between them. This prevents address flagging.

Time Your Shipments Strategically

Customs staffing and scrutiny vary by day and season. Avoid shipping during major holidays when customs is extra alert, and avoid peak season (November-January) when inspection rates spike.

Use Tax-Free Lines Whenever Possible

This bears repeating: tax-free shipping lines effectively remove customs from the equation. The taxes are pre-paid, so your package enters as a legitimate commercial shipment. No declaration anxiety needed.

Final Thoughts on Customs Declarations

Customs declaration is not rocket science, but it does require a bit of thought. The key principles are simple:

1. Be believable — Your declared value should make sense for the weight and contents
2. Be specific — Detailed item descriptions pass inspection more easily than vague ones
3. Be reasonable — Not too low, not too high, just in the sweet spot for your country
4. Use tax-free lines when available — They eliminate most customs risk entirely
5. Buy insurance for valuable hauls — It is cheap peace of mind
