When importing custom signage from China, understanding the correct HS code for signs, import duty, customs documentation, and total landed cost is an important part of the purchasing process.
Custom signs do not have one universal HS code. Classification can vary depending on the sign’s construction, materials, lighting configuration, intended use, product characteristics, and the tariff system of the importing country.
For B2B buyers, an incorrect classification can lead to customs delays, unexpected duties, additional documentation requests, or penalties. Confirming the correct classification helps you estimate landed cost more accurately and prepare the appropriate customs documentation before shipment.
This guide explains how HS codes work for custom signs, which tariff headings may be relevant to different signage products, how import duties are determined, what US buyers should know about Section 301 tariffs on Chinese-origin goods, and which customs documents are commonly required for international signage shipments.
What Is an HS Code for Signs?
An HS code, or Harmonized System code, is a standardized classification system used by customs authorities to identify imported and exported goods.
The first six digits of an HS code are generally based on the international Harmonized System. Individual countries can then extend the classification with additional digits for their own tariff schedules.
For example, the United States uses the Harmonized Tariff Schedule of the United States (HTSUS), while other markets use their own national or regional tariff schedules based on the international HS framework.
The important point for signage buyers is simple:
- There is no single HS code that applies to every custom sign.
- A manufacturer may provide a suggested HS classification for export documentation, but the final import classification should be confirmed according to the tariff schedule and customs requirements of the destination country.
- For large or recurring orders, working with a qualified customs broker is strongly recommended.
Common HS Headings Used for Custom Signs
Several HS headings may be relevant to signage products depending on their construction, materials, lighting configuration, and intended function.
HS Heading 9405 — Lighting Equipment and Illuminated Signage
Heading 9405 covers certain lamps, lighting fittings, illuminated signs, illuminated nameplates, and similar products within the scope of the heading.
Some illuminated signage products, including certain LED signs and illuminated letters, may fall under this heading depending on their design and construction.
However, you should not assume that every LED sign automatically belongs under 9405.
The correct classification can depend on how the product is constructed and how the applicable customs authority interprets the tariff heading.
HS Heading 8310 — Certain Base-Metal Sign Plates and Similar Articles
Heading 8310 covers certain base-metal sign plates, name plates, numbers, letters, and similar articles.
This heading may be relevant to certain non-illuminated metal signage products.
For example, some stainless steel or aluminum sign plates may require consideration under this heading, but the material alone does not determine classification.
The exact product construction and destination-country tariff schedule must still be reviewed.
HS Chapter 39 — Certain Plastic and Acrylic Products
Plastic and acrylic signage components may fall under tariff classifications within Chapter 39 in some circumstances.
For example, certain acrylic letters, plastic components, or non-illuminated plastic signage may require classification under an applicable plastics heading.
However, it is not correct to assume:
- Acrylic sign = one universal HS code.
The product’s construction, function, manufacturing method, and destination-country tariff rules can affect the final classification.
Why Classification Cannot Be Based on Material Alone
Two signs made from stainless steel may have different classifications if one is an illuminated sign assembly and the other is a non-illuminated metal plate.
Likewise, two acrylic products may receive different classifications depending on their construction and intended function.
When reviewing an HS code, consider:
- Whether the sign is illuminated
- Primary function of the product
- Main construction materials
- Electrical components
- Product configuration
- Whether it is a complete sign or a component
- Intended use
- Destination-country tariff rules
For significant shipments, have a qualified customs professional confirm the final classification.
How Import Duty on Custom Signs Is Calculated
Import duty is generally determined by applying the applicable tariff rate to the customs value of the imported goods.
The actual calculation can depend on several factors:
- HS or tariff classification
- Country of origin
- Customs value
- Importing country
- Applicable additional tariffs
- Trade agreements or preferential programs
- Trade remedies or special tariff measures
- Product-specific exemptions or exclusions
This means you should not estimate the total import cost using the product price alone.
A simplified landed-cost calculation can look like:
Landed Cost = Product Cost + International Freight + Insurance + Import Duty + Import Taxes + Customs Fees + Local Delivery
The exact calculation varies by country and shipment.
If you are importing custom signs manufactured in China, the country of origin can affect the applicable tariff treatment.
Import Duty on Signs from China
China-origin products may be subject to additional duties or trade measures in certain markets.
For this reason, B2B buyers should confirm both:
- The correct tariff classification
- The current tariff treatment for Chinese-origin goods
Do not rely on an old quotation, previous shipment, or historical tariff rate when calculating the cost of a new project.
Tariff schedules and additional trade measures can change over time.
US Section 301 Tariffs and Chinese-Made Signs
US buyers importing signage manufactured in China should pay particular attention to Section 301 tariffs.
The United States has imposed additional tariffs on certain Chinese-origin products under Section 301. Whether an individual signage product is subject to an additional tariff depends on its applicable HTSUS classification and the tariff measures in effect at the time of importation.
This means you should not assume that all Chinese-made signs have the same Section 301 tariff rate.
Before placing a large order, ask your customs broker to verify:
- The applicable HTSUS classification
- Country of origin
- Whether the classification is subject to Section 301
- The applicable additional tariff rate
- Any current exclusions or special provisions
- The total estimated duty and tax liability
For high-value or recurring imports, confirming the classification before shipment can help prevent unexpected landed-cost increases.
How to Estimate the Landed Cost of Imported Signs
Factory price is only one part of the total purchasing cost.
For example, a B2B buyer importing custom illuminated letters may need to consider:
Product Price
The manufacturer’s price for the signs, including agreed materials, lighting, finishes, mounting hardware, and other specifications.
Export Packaging
Custom signage may require protective film, foam, individual cartons, reinforced packaging, wooden crates, or other export-grade protection.
International Freight
Depending on the project, this may include ocean freight, air freight, courier transportation, or other shipping methods.
Import Duty
The applicable tariff depends on the final classification, country of origin, customs value, and current tariff rules.
Import Taxes
Some countries impose VAT, GST, sales taxes, or other import-related taxes.
Customs and Brokerage Fees
These can include customs broker charges, documentation fees, terminal fees, inspection charges, and other local costs.
Local Delivery
After customs clearance, the shipment may still require transportation from the port, airport, or customs facility to the final destination.
This is why comparing suppliers based only on factory price can produce misleading results.
A supplier with a slightly higher unit price may still provide a lower total landed cost if the packaging, shipping arrangement, product specifications, and documentation are better suited to the project.
Customs Clearance Documents for Sign Imports
The exact documentation required varies by destination country, product type, shipping method, and customs authority.
Common documents may include:
Commercial Invoice
The commercial invoice normally identifies:
- Seller
- Buyer
- Product description
- Quantity
- Unit price
- Total value
- Currency
- Country of origin
- Applicable trade terms
Use clear product descriptions rather than vague terms such as “signage products.”
Packing List
The packing list may include:
- Number of cartons or crates
- Product quantities
- Package dimensions
- Gross weight
- Net weight
- Package markings
This information helps freight forwarders and customs authorities process the shipment.
Bill of Lading or Air Waybill
The transport document confirms shipment details and is required for the applicable freight method.
Certificate of Origin
A certificate of origin identifies where the goods were manufactured.
It does not automatically reduce import duty.
Preferential tariff treatment only applies where the relevant trade agreement, preference program, or local customs rules provide for it.
Product and Compliance Documents
Depending on the destination market and project, additional technical documents may be requested.
These can include:
- Product specifications
- Electrical component datasheets
- Declarations of conformity
- Applicable test reports
- Certification information
- Material documentation
- IP rating documentation
Remember that customs clearance and installation compliance are not the same thing.
A document that supports customs or import requirements does not automatically mean the sign is approved for installation under local electrical or building regulations.
Should You Use the Manufacturer’s HS Code?
Manufacturers and exporters often provide a suggested HS code for export documentation.
This can be a useful starting point, but importers should not automatically assume that the supplier’s classification is the final classification required in the destination country.
The same product can be treated differently under the tariff schedules and customs practices of different jurisdictions.
For significant orders, ask your customs broker to review:
- Product photographs
- Technical drawings
- Materials
- Product dimensions
- Lighting configuration
- Electrical components
- Intended use
- Manufacturer’s proposed HS code
Providing complete product information allows the broker to make a more informed classification decision.
How to Verify an HS Code Before Shipping
Before booking freight for a large signage order, use the following process.
Step 1: Identify the Complete Product
Do not classify the product using a short name such as:
- “LED sign”
Instead, document the actual product:
- Illuminated or non-illuminated
- Stainless steel, aluminum, acrylic, or other materials
- Channel letters, logo sign, wayfinding sign, or other construction
- Complete assembly or component
- Intended commercial application
Step 2: Confirm the Country of Origin
Country of origin affects the applicable tariff treatment.
For custom signs manufactured in China, clearly document China as the manufacturing origin where applicable.
Step 3: Review the Destination Tariff Schedule
Check the tariff schedule used by the importing country.
For US shipments, this means reviewing the applicable HTSUS classification and any additional tariff measures.
For other markets, use the relevant national or regional tariff database.
Step 4: Ask Your Customs Broker to Confirm
For high-value orders, recurring imports, or products with uncertain classification, have a qualified customs professional review the classification before shipment.
Step 5: Keep Supporting Documentation
Keep copies of:
- Commercial invoices
- Product specifications
- Technical drawings
- Product photographs
- Supplier quotations
- HS classification information
- Customs broker advice
- Relevant tariff references
These records can be useful if customs authorities request additional information.
HS Code vs. Product Category: Why the Difference Matters
A common mistake is assuming that a website product category determines the customs classification.
For example, a manufacturer may describe a product as:
But customs classification is not determined by the marketing name alone.
The customs authority may consider:
- Product function
- Construction
- Lighting system
- Materials
- Electrical configuration
- Intended use
- Applicable tariff rules
This is why your website product category, sales description, and customs classification do not necessarily have to be identical.
The important requirement is that the customs declaration accurately describes the actual imported product.

Final RFQ Submission Checklist
Before sending your RFQ, make sure you can answer these questions:
- What are you buying? — Sign type, artwork, dimensions, quantity, materials, finish, and application.
- How should it work? — Lighting type, LED color, voltage, electrical components, IP rating, and certification requirements.
- How should it be installed? — Mounting method, installation surface, location, and environmental conditions.
- Where is it going? — Destination country, city, shipping method, Incoterm, and required delivery date.
- What documents do you need? — Commercial invoice, packing list, origin information, certification documents, technical files, and any customs-specific requirements.
- What commercial terms do you expect? — Unit price, total price, production lead time, packaging, payment terms, warranty, tooling, and sample costs.
A complete RFQ gives the manufacturer enough information to prepare a quotation based on the same specification you will ultimately use for production and shipping.
For international B2B signage projects, the RFQ should be finalized before comparing supplier prices. This makes it easier to compare quotations on a true like-for-like basis and reduces the risk of unexpected costs after the purchase order is issued.
Common Customs and HS Code Mistakes
Assuming Every Sign Has the Same HS Code
Illuminated signs, non-illuminated metal signs, plastic signage, components, and complete assemblies may require different classifications.
Choosing an HS Code Only Because It Has a Lower Duty Rate
Never select a tariff classification simply because it results in a lower duty.
The classification should reflect the actual product and applicable customs rules.
Describing a Sign Incorrectly
Do not describe an illuminated sign as a generic “metal plate” simply to obtain a different tariff treatment.
Misclassification or inaccurate declarations can create customs, financial, and legal risks.
Assuming the Exporter’s Code Is Automatically Correct
The manufacturer’s suggested HS code may be useful, but the importing country’s classification rules still need to be considered.
Using an Old Tariff Rate
Tariff schedules and additional trade measures can change.
Always verify current rates before placing a large order.
Ignoring the Difference Between Duty and Tax
Import duty is only one part of the total import cost.
VAT, GST, sales tax, customs fees, brokerage, freight, and local delivery may also affect the final landed cost.
Confusing Customs Clearance With Installation Approval
A shipment clearing customs does not automatically mean the sign can legally be installed.
Electrical certification, building codes, permits, and local authority requirements may be separate issues.
HS Code and Customs FAQ for Custom Sign Buyers
What is the HS code for LED signs?
There is no single universal HS code for every LED sign.
Some illuminated signage products may fall under HS heading 9405, while other signage products may require classification under different headings depending on their construction, materials, function, and destination-country tariff rules.
For commercial imports, confirm the final classification with a qualified customs professional.
What is the HS code for metal signs?
Certain non-illuminated base-metal sign plates, letters, numbers, and similar products may fall under heading 8310.
However, not every metal sign belongs under this heading. The exact construction and applicable destination-country tariff schedule must be reviewed.
What is the HS code for acrylic signs?
Acrylic and other plastic signage products may fall under classifications within Chapter 39 in some circumstances.
The correct classification depends on the product’s construction, function, and applicable customs rules.
How much import duty do I pay on signs from China?
There is no single duty rate for all signs imported from China.
The final duty can depend on:
- Product classification
- Country of origin
- Customs value
- Destination country
- Additional tariff measures
- Applicable trade programs
For US imports, Chinese-origin products may also be subject to additional Section 301 duties depending on their HTSUS classification.
Do US imports of Chinese signs have Section 301 tariffs?
Some Chinese-origin products are subject to additional Section 301 tariffs.
Whether a particular sign is subject to an additional tariff depends on its applicable HTSUS classification and the tariff measures in effect at the time of import.
Always verify the current treatment before ordering.
Does a certificate of origin reduce import duty?
Not automatically.
A certificate of origin documents the manufacturing origin of the goods. Preferential duty treatment only applies when the relevant trade agreement, preference program, or customs rules provide for it.
What customs documents are needed to import custom signs?
Common documents include a commercial invoice, packing list, bill of lading or air waybill, and country-of-origin information.
Depending on the destination market and product, customs or other authorities may also request technical, electrical, conformity, or product documentation.
Can the sign manufacturer provide the HS code?
Yes. Manufacturers commonly provide a suggested HS code for export documentation.
However, importers should confirm the classification against the tariff schedule of the destination country, particularly for large or recurring shipments.
Should I confirm the HS code before placing a large sign order?
Yes.
For high-value projects, confirming the tariff classification before production and shipment helps you estimate landed cost more accurately and reduces the risk of unexpected customs issues.
