International Shipping Customs Forms Explained: What Monroe Residents Need to Know Before Sending a Package Abroad

Every international package that leaves the United States must clear customs at the destination country. The paperwork you attach determines whether that process takes hours or weeks — and whether your package arrives at all.

---

You've packed the box. You've got the address. You're ready to ship from Monroe. Then the counter staff asks: "Do you have your customs declaration?" And suddenly the process feels a lot more complicated than you expected.

International shipping from Monroe, WA involves documentation requirements that don't exist for domestic shipments. Get them right, and your package clears customs quickly. Get them wrong, and it could sit in a foreign warehouse for weeks — or come back to you with duties unpaid, items confiscated, or the whole thing refused.

The Mail Station Monroe handles international shipments every day for Monroe-area residents, RVers, military families, online sellers, and businesses. This guide explains the core customs forms, what each field means, how to avoid the most common mistakes, and which carriers handle international paperwork best.

Why Customs Documentation Matters More Than You Think

Customs authorities in every country exist to control what crosses their borders. Their tools are the declarations you submit with your package. When a customs officer opens your shipment — and they do open packages regularly — they compare what's inside against what you declared. Discrepancies create problems:

• Misdeclared value → additional duties assessed, package held, potential penalty
• Wrong or missing HS code → classification delay, wrong duty rate applied
• Prohibited item → confiscation, return, or destruction (no refund)
• Incomplete sender information → package stuck in customs limbo
• "Gift" marked incorrectly → reduced duty threshold exceeded, recipient charged unexpectedly

The customs form isn't a formality. It is the legal declaration that governs your package's passage through a foreign country's border. Fill it out carefully.

The Three Main Customs Forms

CN22 — Small Packets and Parcels via USPS

The CN22 is a small green sticker-style customs declaration used for USPS international mail. It's the simplest form and is required for packages sent via:

• First-Class Package International
• Priority Mail International (for lower-value items)
• USPS ground economy international (formerly First-Class Package International)

The CN22 has fields for:

• Category of item: gift, commercial sample, returned goods, other
• Detailed description of contents — required; "clothing" or "misc items" is not sufficient
• Quantity and weight of each item
• Value of each item (declared in USD)
• Country of origin for each item
• HS tariff number (optional on CN22, but recommended)

The CN22 is appropriate for packages valued at $400 or less. Above that threshold, the CP72 is required.

CP72 — Larger International Parcels via USPS

The CP72 (also called the PS Form 2976-B) is the full customs declaration form for USPS international packages above $400 in value. It's also required for certain destination countries regardless of value. The CP72 includes all the CN22 fields plus:

• Full sender name and address
• Full recipient name and address
• HS tariff code (required)
• Reason for export: sale, gift, sample, return, repair, personal use
• Certification signature and date

Most USPS international packages shipped at The Mail Station Monroe requiring a CP72 are completed at the counter with staff assistance. If you're preparing a shipment in advance, bring the complete item descriptions, values, and quantities — we'll handle the rest.

Commercial Invoice — Required for FedEx and DHL International

For international shipments via FedEx or DHL, the primary customs document is the commercial invoice — not a USPS form. A commercial invoice is required for virtually all FedEx and DHL international shipments and must include:

• Exporter/shipper information: full name, address, phone, email
• Importer/recipient information: full name, address, phone, email (critical — missing recipient phone numbers are a top cause of customs delays)
• Invoice date and number
• Terms of sale (Incoterms): most consumer shipments use "DAP" (Delivered at Place) — recipient pays duties; "DDP" (Delivered Duty Paid) means the shipper pays all duties upfront
• Country of origin for each item
• HS tariff code for each item
• Detailed item descriptions: specific, not generic — "stainless steel chef's knife, 8-inch blade" rather than "kitchen item"
• Quantity, unit price, and total value per line item
• Currency
• Reason for export
• Signature

FedEx and DHL have online tools that generate commercial invoices when you create a shipment label. At The Mail Station Monroe, our staff helps complete commercial invoices correctly at the counter — particularly important for high-value, fragile, or unusual items.

HS Codes: The Classification That Controls Your Package

The Harmonized System (HS) tariff code is a standardized numerical code used by customs authorities worldwide to classify goods. Every item you ship internationally has an HS code. That code determines:

• What duty rate the recipient country applies
• Whether the item is restricted or prohibited
• Whether additional permits or certifications are required

For most consumer goods shipped from Monroe, the HS code is a 6-digit number (expanded to 10 digits in the US Harmonized Tariff Schedule). Common categories:

You can look up HS codes using the USPS International Mail Manual, the FedEx or DHL online tools, or the US Census Bureau's Schedule B search tool at census.gov. When in doubt, ask at the counter — our staff at The Mail Station Monroe regularly helps customers find the right classification for unusual items.

Declared Value: The Honest Number

International customs declarations require a declared value — the actual market value of the item being shipped, in US dollars. This number matters for three reasons:

1. Duty calculation: destination countries apply duty as a percentage of declared value. Undervalue your goods, and you're making a false customs declaration — a federal offense.
2. Duty-free thresholds: most countries have a de minimis threshold below which no duty is assessed. Canada's is CAD $20 for postal imports (though the threshold for courier shipments rose to CAD $150 in recent years). The UK's is £135. Japan's is ¥10,000. Germany and other EU countries apply duty on goods above €150.
3. Shipping insurance: the declared customs value may affect the maximum payout if your package is lost or damaged in transit. Always insure high-value shipments separately from the customs declaration.

Marking a commercial item as a "gift" to reduce duty is customs fraud. Gifts have their own duty rules — and the exception is for legitimate personal gifts between individuals, not commercial merchandise. Customs officers flag mismatched declarations routinely.

Prohibited and Restricted Items: What You Cannot Ship Internationally

Every country maintains its own list of prohibited imports. Some restrictions are universal; others are country-specific. Common international shipping restrictions that affect Monroe customers include:

Universally Restricted by Most Carriers and Countries

• Lithium batteries (standalone, not installed in devices) — require special labeling and handling; many carriers restrict quantity per package
• Aerosol cans — considered hazardous for air transport
• Perishables — restricted or prohibited without proper permits and packaging
• Firearms and ammunition — strict licensing and permit requirements
• Alcohol — prohibited or heavily regulated by most countries; requires exporter and importer licenses
• Tobacco and related products — import restrictions vary significantly by country
• Counterfeit goods — illegal to ship anywhere

Country-Specific Restrictions That Surprise Monroe Shippers

Canada: Fresh fruits and vegetables, certain meat products, plants, and seeds require Canadian Food Inspection Agency (CFIA) permits. Firearms and bear spray (yes, the kind sold widely in Washington State outdoor stores) are heavily regulated or prohibited as imports.

United Kingdom: Post-Brexit, UK imports require full customs clearance even from close US trading partners. CITES-protected animal products (ivory, certain feathers, some leather goods) are restricted. CBD products face uncertain legal status.

Philippines: Strict limits on personal effect exemptions. Meat and certain food items restricted. Currency and precious metals have specific declaration requirements.

India: Electronics and mobile phones above certain values require import permits. Foreign currency above $5,000 requires declaration. Many restricted agricultural products.

Mexico: Many food items, plants, and seeds restricted. Certain firearms parts and accessories prohibited. Used clothing and household goods require documentation above value thresholds.

The Five Most Common Customs Mistakes — And How to Avoid Them

After handling international shipments from Monroe for decades, The Mail Station Monroe has seen the same mistakes trip up shippers repeatedly:

1. Vague item descriptions. "Household goods," "personal items," "merchandise," and "clothing" are not acceptable customs descriptions. Write "3 men's cotton t-shirts, size L" or "1 stainless steel water bottle, 32 oz." Customs officers need to know exactly what's in the box.

2. Missing recipient phone number. FedEx and DHL require a working recipient phone number for customs clearance. Without it, the carrier cannot contact the recipient to resolve holds, and packages sit in customs. Always provide it.

3. Incorrect country of origin. If you're shipping a product made in China with a US brand label, the country of origin is China — not the US. Getting this wrong can result in additional duties or customs holds.

4. Inconsistent values across documents. If your commercial invoice says $50 and your shipping insurance is declared at $500, customs will notice the discrepancy. Values should be consistent across all documentation.

5. Shipping prohibited items by accident. "I didn't know it was restricted" is not a customs defense. Before shipping any food, plant-based product, animal product, medication, battery, or anything potentially regulated, verify the destination country's rules. Our staff at The Mail Station Monroe can help identify common restrictions for the countries we ship to regularly.

FedEx vs. DHL vs. USPS: Which Is Better for Customs Clearance?

For most Monroe residents shipping meaningful items internationally — gifts, merchandise, documents, personal effects — FedEx or DHL is the better choice because their customs brokerage is integrated and their tracking through the destination customs process is far superior to USPS. For low-value items where cost is the primary concern and tracking is less critical, USPS can be appropriate.

US Tariffs and Changing Trade Policy: What Monroe Shippers Should Know in 2026

Trade policy changes in 2025 and 2026 have created new complexity for international shippers, particularly affecting goods with Chinese origin. The de minimis exemption — which previously allowed packages valued below $800 to enter the US duty-free — has faced significant legislative scrutiny, and several countries have modified their own thresholds in response to global trade pressures.

If you're shipping internationally for business — as a Monroe-based e-commerce seller, exporter, or retailer — staying current on tariff changes is important. Our US Tariffs and International Shipping guide covers the 2025–2026 tariff environment and how it affects Monroe shippers on both inbound and outbound shipments.

Why Monroe Residents Use The Mail Station for International Shipping

Walking into a carrier's retail location with an international package is not always straightforward. Self-service kiosks don't help you choose the right form. Online shipping tools assume you already know what HS code applies to your hand-carved wooden bowl.

At The Mail Station Monroe, international shipping includes:

• Customs form assistance at the counter — we help you fill out CN22, CP72, and commercial invoices correctly, with the right item descriptions, values, and HS codes
• Multi-carrier options — FedEx, DHL, and USPS under one roof; we recommend the best service for your destination, timeline, and budget
• Prohibited item screening — before we accept your package, we help identify any items that might be restricted in your destination country
• Packaging for international transit — international packages face more handling than domestic; we pack fragile or high-value items to survive the journey
• Insurance options — declared value on the customs form is not the same as shipping insurance; we help you add appropriate coverage for valuable items

For Monroe families sending care packages to relatives abroad, RVers shipping gear internationally, online sellers managing international returns, and businesses exporting products — The Mail Station Monroe handles the paperwork so you can focus on what you're actually shipping.
