Buying products from overseas can look straightforward at first. You find a supplier, get a quotation, approve a sample, and place the order. The complications often start after that.
When the destination is the US or the UK, there are customs rules, product requirements, shipping costs, taxes, and paperwork to deal with. A supplier may offer a very attractive price, but that does not necessarily mean the product will be cost-effective once it reaches the customer.
That is why it is worth doing a little more work before placing a large international order.
Be Clear About the Product You Need
Start with the product itself. Do not depend only on a product name or a supplier’s catalogue description.
Get the details that will matter later, especially if you are importing regularly.
Ask for:
- Exact product specifications
- Materials and components
- Intended use
- Country of manufacture
- Product dimensions and weight
- Packaging details
- Available test reports or certificates
For example, two products may look almost identical in a photograph but have different materials, specifications, or intended uses. Those differences can affect classification, compliance, and even the final import cost.
Getting this information at the beginning also makes it easier to compare quotations from different suppliers.
Check the Customs Code Before Ordering
The customs classification should not be treated as something to sort out after the goods are ready for shipment.
In the US, imported goods are classified under the Harmonised Tariff Schedule (HTS). The schedule is updated during the year, and the USITC published Revision 19 on September 15, 2026.
The UK uses commodity codes for imports. The code helps determine Customs Duty and import VAT and can also indicate whether a licence or other requirement applies.
A supplier might give you a tariff code, but it is still worth checking it for the destination country. The code used in one country does not automatically guarantee the same will use in another country.
If classification is uncertain, businesses importing into Great Britain can also apply for an Advance Tariff Ruling. A legally binding decision is generally valid for three years and can provide more certainty about classification.
Look at US Requirements Separately
The US should not be treated as simply another delivery destination. Depending on what you are importing, there may be additional requirements beyond ordinary customs clearance.
Before shipping, check things such as:
- HTS classification
- Applicable duties
- Country-of-origin marking
- Product-specific regulations
- Required permits or approvals
- Customs documentation
- Who will act as the importer of record
This becomes particularly important with products such as electronics, machinery, children’s products, food-related items, chemicals, and other regulated goods.
One practical mistake businesses make is checking these requirements only after choosing a supplier. It is usually better to check them while comparing suppliers, because compliance requirements can affect the product specification itself.
Know What the UK Requires
Importing into the UK has its own process. Businesses importing into England, Scotland, or Wales generally need a GB EORI number. Different arrangements can apply when goods move to or from Northern Ireland.
You also need the correct commodity code and the customs value of the goods. These details are used when calculating duty and VAT and completing the import declaration.
Before the supplier ships, check:
- Whether the product needs an import licence
- Whether any certificates are required
- Whether the product has specific labelling rules
- Whether the supplier can legally export it
- Who will make the customs declaration
Many UK businesses use a customs agent or transporter to handle declarations, but the importer still needs to provide accurate product and commercial information.
Don’t Calculate Cost From the Supplier Quote Alone
This is where some sourcing decisions go wrong.
Imagine a supplier quotes $4 per unit while another quotes $4.40. The first option looks cheaper. But what happens if its packaging is unsuitable, freight costs more, inspection is needed, or customs charges are higher?
Your calculation should include the costs that come after the factory price:
- International freight
- Insurance
- Customs duty
- Import taxes
- Customs clearance
- Port or handling charges
- Inspection
- Warehousing
- Local delivery
Work out the landed cost per unit before deciding which quotation is actually better.
For a business placing repeat orders, this number is often more useful than the factory price by itself.
Spend Time Checking the Supplier
A supplier’s website can tell you what they sell. It does not tell you everything about how they operate.
Before committing to a large order, ask practical questions. How long have they been making the product? Can they provide samples? What happens if part of the order fails inspection? Can they maintain the same specification for future batches?
It is also worth checking lead times carefully. A supplier who promises ten days but regularly takes three weeks can create more problems than a supplier who honestly quotes three weeks from the start.
For a new supplier, a smaller first order can be useful. It gives you a chance to see how they handle quality, packaging, documents, communication, and shipping before you increase the volume.
Keep the Paperwork Consistent
Small differences between documents can create unnecessary questions.
Check that the information on the commercial invoice, packing list, product documents, and shipping paperwork matches.
Pay particular attention to:
- Product description
- Quantity
- Product value
- Country of origin
- Weight
- Classification
- Packaging information
If the invoice says one thing while the packing list describes the goods differently, someone may need to stop and clarify the shipment.
It is a simple check, but it can save time.
Don’t Assume Rules Will Stay the Same
Import requirements change. Tariff schedules are updated, and customs procedures can be revised during the year. The US HTS, for example, has had multiple revisions in 2026.
UK customs guidance is also updated periodically. Current UK guidance confirms that commodity codes can affect duty, licences, and declaration requirements.
Think About the Second Order Too
Good sourcing is not only about getting the first shipment delivered.
If the product sells well, can the supplier produce the same quality again? Can they handle a larger quantity? Will the packaging remain the same? Can they maintain reasonable lead times?
These questions are easy to overlook when everyone is focused on getting the first order out.
How Zairyo Plus Can Help
International sourcing involves more than finding a factory and negotiating a price. Product research, supplier checks, documentation, shipping, customs requirements, and landed costs all have to work together.
Zairyo Plus can help businesses looking to source products for the US and UK markets with a more organised approach. Having the right information before placing an order can make supplier comparisons easier and reduce avoidable problems later.
Final Thoughts
The cheapest quotation is not always the cheapest shipment. A product can look attractive on paper and become expensive once freight, duty, compliance, and other costs are included.
Before sourcing for the US or UK, take time to understand the product, check its classification, look at the destination requirements, verify the supplier, and calculate the actual landed cost.
A little checking before the order is placed can prevent much bigger problems after the goods are already on their way.
