What is PS Form 2976-A?
PS Form 2976-A is a full-page USPS customs declaration form (CN 23) used for international mail that requires detailed documentation. It is the same as Customs Declaration CN 23 in international postal systems. The form provides space to list multiple items individually, include detailed descriptions, declare accurate values, and provide additional information required by customs authorities. Unlike the small adhesive CN 22 label, PS Form 2976-A is printed on letter-sized paper and placed in a clear envelope pouch attached to the outside of your package.
Electronic Customs Forms (PS Form 2976-R)
USPS now generates customs forms electronically using PS Form 2976-R at the counter or through Click-N-Ship online. Older hand-written barcoded 2976-A forms are obsolete. At the post office, the clerk creates the form electronically based on your package information. For mailing at home, use Click-N-Ship which automatically generates the correct USPS international shipping form based on your service and destination.
When to Use PS Form 2976-A
You typically use PS Form 2976-A (the USPS customs declaration form CN 23) instead of PS Form 2976 when:
- Higher-value shipments: Merchandise shipments typically over $400 generally require the detailed CN 23 customs form, though exact thresholds depend on the USPS service and destination
- Package weight or size: Exceeds limits for CN 22 adhesive labels
- Multiple items requiring detailed inventory: Packages with many items that need itemized listing and won't fit on the small CN 22 label
- Commercial shipments: Items being sold commercially require detailed invoicing for USPS international package customs requirements
- Service requirements: Some USPS international shipping services (like certain Priority Mail International options) require CN 23 regardless of value—always check USPS rules for your specific service
- Country requirements: Some countries require CN 23 regardless of value (check USPS country restrictions)
Common use cases:
- Sending high-value gifts (jewelry, electronics, artwork)
- International business shipments with multiple products
- Packages containing items from multiple categories requiring separate listing
- Priority Mail International parcels with merchandise (some flat-rate formats have separate value limits—check USPS rules for your specific service)

- Individual values: Show the total value for grouped items on one line

Where do I get PS Form 2976-A?
USPS now generates customs forms electronically (often using PS Form 2976-R at the counter or Click-N-Ship online). Older hand-written barcoded 2976-A forms are obsolete.

Harmonized System (HS) tariff numbers are international product classification codes. They are optional for personal shipments but recommended for commercial shipments to speed customs clearance and determine duties.

What is the difference between PS Form 2976-A and PS Form 2976-R?
PS Form 2976-R is the electronic intake worksheet USPS now uses to generate customs forms at the counter or through Click-N-Ship online.

When you provide information via 2976-R, the system automatically prints either a CN 22 or CN 23 customs declaration (2976-A when detailed) based on your package details, service, and destination. The final printed CN 23 form is what you attach to your package.
Do I still need a clear customs pouch for electronically-generated forms?
Yes. Whether the customs form is hand-written or electronically generated via PS Form 2976-R, you still need to place the completed CN 23 form in a clear customs pouch and attach it securely to the outside of your package. The pouch protects the form during transit and keeps it visible for customs officials. USPS provides these pouches at no cost at post office counters.
