, new customs changes mean accurate Country of Origin (CoO) documentation is now a must. As of August 29, 2025, the 

USA has suspended its de minimis threshold

, so all shipments are subject to duty and tax, with rates depending on origin and classification.

, including proof of origin, before offering 

In this guide, we'll help you understand why CoO matters, what counts as Singapore origin, and how to document and verify it for hassle-free DDP shipping.

When shipping to the USA under the new rules:

: Duties depend on your product’s HS code and country of origin.

: USA Customs may impose extra tariffs, including surcharges of up to 40%. The good news is that with the right documents, avoiding this risk is straightforward

: Logistics companies must trust your declarations before they prepay duties on your behalf. That means you must provide credible documents to pass KYC.

Without clear origin proof, shipments may face delays or added costs.

This raises the question: what actually qualifies as “Made in Singapore”?

What Qualifies as “Made in Singapore”

Goods can be declared Singapore-origin if they are:

 in Singapore, meeting one of these criteria:

—like relabeling, simple assembly, or repackaging—does not qualify.

Most sellers find “substantial transformation” the trickiest to evaluate. Let’s break that down with examples.

“Substantial transformation” is the test used by both Singapore Customs and USA Customs to decide if your processing is enough to justify a Singapore origin claim. The key question is: did your processing in Singapore create a new product with a new name, character, or use?

: Importing finished jewelry from overseas and reselling it in Singapore without further processing.

: Importing raw materials from overseas and handmaking the jewelry in Singapore, turning them into the final products you sell.

: Importing ready-made shirts from China and just adding brand tags.

: Importing fabric from China and cutting, sewing, and tailoring in Singapore into finished apparel.

: Importing fully assembled circuit boards from China, then only mounting them in plastic casings in Singapore.

: Importing discrete components and performing PCB assembly, soldering, firmware programming, and final device assembly in Singapore.

: Importing packaged cookies from Malaysia and reboxing them.

: Importing raw cocoa beans and processing them into chocolate in Singapore.

 clearly stating “Country of Origin: Singapore”

For KYC purposes, carriers often accept any one of these. However, the strongest proof is an official Certificate of Origin.

How to Apply for an Official Certificate of Origin

Register your manufacturing premises (about 1 month).

Submit a Manufacturing Cost Statement (7 working days).

Apply via TradeNet (linked to your export permit).

Renew your MCS annually (2 working days).

Ensure consistency across invoices, Certificate of Origin, and shipping forms.

Avoid misdeclaration, as penalties include fines, seizures, and tariffs.

Prepare sample documents for KYC ahead of time.

Even with the right knowledge, many sellers need a partner to help them operationalise compliance. This is where JustShip can support you.

With the USA de minimis threshold removed, proving origin is no longer optional. At JustShip, we make this transition easier by combining 

DDP shipping with a built-in KYC verification process

We work with all types of sellers, from registered businesses to small-scale home brands.

Here is what we need from you to get started:

Brand or legal name, store URL, contact email, and phone number. (UEN optional)

Typical categories and your top 1 to 3 SKUs.

3. Country of Origin proof for 1 to 3 SKUs

Supplier or manufacturer invoice that states the origin, or

Supplier or manufacturer declaration of origin, or

Clear product label photos showing “Made in ___”, or

Certificate of Origin (if you already have one).

Use the email registered to your JustShip seller account and send the above details to 

1. We validate your documents and HS codes.

2. We confirm your DDP activation and share any product-specific guidance.

3. You can start creating compliant DDP shipments to the USA.

1. Do I need an official Certificate of Origin for every export?

Not always. An official Certificate of Origin is not mandatory for every shipment. For smaller ecommerce parcels, carriers may accept simpler proof such as a supplier invoice or a declaration that states “Country of Origin: Singapore.” 

For most ecommerce sellers, invoices and declarations are sufficient for KYC. You can then apply for official Certificate of Origin selectively, such as for high-value or high-risk shipments.

2. What if I manufacture the products myself and do not have supplier invoices?

SingPost and Major Postal Operators Suspend Shipments to the US

, which is the most expensive option in their service portfolio.

SingPost is not the only postal operator taking this step. Other providers, including 

Belgium Post and European postal networks

, have already announced similar suspensions. These restrictions are a direct result of new US customs regulations that require every commercial shipment, regardless of size or value, to be tracked, fully documented, and subject to duties.

 who relied on cheaper packet services, this marks 

the end of budget-friendly lanes into the US.

Why Are Postal Providers Suspending Shipments to the US?

The US has introduced stricter customs requirements in 2025, and postal providers can no longer keep up. The key changes are:

, the USD 800 duty-free threshold is gone. All shipments are now subject to duties and taxes.

: Every parcel, no matter how small, must include end-to-end tracking and proper customs paperwork.

: All shipments must be declared with a valid 10-digit HS (Harmonized System) code. This determines the duty rate applied, and on top of that the US has added a 

 for Singapore, with higher rates for other origins. To help sellers adapt, 

JustShip will launch AI-powered HS code suggestions on 1 September 2025

, making it easier to classify products correctly and reduce delays.

: Postal services cannot provide this level of compliance at economy pricing, which is why they are suspending their lanes.

Sellers who relied on economy postal options now face premium courier pricing. This reduces margins or forces price increases.

Economy services are disappearing, leaving sellers with only express solutions. Customers lose the option of slower, cheaper delivery at checkout.

Every parcel now requires duties, accurate paperwork, and correct HS codes. Sellers must declare Country of Origin and ensure duties are prepaid or accurately assessed. Errors can cause delays, penalties, or returns.

Q: Will the end of the de minimis clause affect shipping?

Yes. The removal of the US de minimis threshold means that all shipments, regardless of value, are now taxed. Previously, items under USD 800 could enter duty-free. Now, every parcel must clear customs and duties, which is why postal services are shutting down their cheaper packet options.

Q: Will postal services come back in the future?

It is uncertain. This depends on how US tariff laws evolve. For now, postal providers cannot comply with the rules, so they have suspended their services. If regulations change again, some cheaper postal options may return, but sellers should not rely on this.

. Expect DDP handling fees from SGD 12.50 for Express and SGD 10 for Select.

Q: How do HS codes affect my shipments now?

Every shipment must now include a valid 10-digit HS code for customs clearance. Without it, your parcel may be delayed, fined, or rejected at US customs. To make this easier, JustShip will launch an 

early September 2025 to suggest the right codes based on your product descriptions.

Q: Are there any order limits for e-commerce shipments under the new rules?

No strict limits have been announced. The change is that all parcels, regardless of size or frequency, must clear customs. Sellers should ensure HS codes and item values are accurate to avoid problems.
