Carbon Fiber Tube HS Code: Export and Import Classification Guide

Introduction

The carbon fiber tube HS code is the six-digit tariff classification that customs authorities use to identify a shipment, set its duty, and check it against trade rules. Choosing the right code matters because a mismatch between the goods and the declared classification can hold a consignment, trigger a penalty, or apply the wrong duty rate. Carbon fiber tubes sit in a heading that was reorganised in the 2022 edition of the Harmonized System, and getting the carbon fiber tube HS code right starts with one question: is the shipment raw fiber, a fabric or prepreg, or a finished article such as a pultruded or roll-wrapped tube? The answer decides which subheading applies, and it is the difference between a clean entry and a customs query.

This guide explains how classification works, maps the codes that apply to tubes and related products, covers the HSN extension used in India, and sets out the documents and supplier questions that keep a shipment compliant.

How Carbon Fiber Tube HS Code Classification Works

The Harmonized System is a hierarchy administered by the World Customs Organization: chapters, headings, and subheadings that every member country uses for the first six digits. Countries then add national digits for duty and statistics, so the same six-digit code can carry a longer national number in the United States, the European Union, China, or India. Three principles decide where a carbon fiber tube lands:

• Essential character: Classification follows the material that gives the product its essential character. For a carbon fiber reinforced tube, that is the carbon fiber, not the polymer matrix.
• Level of processing: Raw fiber, fabric, and finished articles sit in different subheadings of the same heading, so the form of the goods matters as much as the material.
• Not elsewhere specified: Heading 6815 is a residual heading for articles of stone and other mineral substances not covered elsewhere, so it captures carbon fiber goods that are not classified as textiles or plastics.

Because of the second principle, a shipment of carbon fiber tow and a shipment of finished tubes can share a heading but not a subheading. Declaring the wrong level is the most common classification error in this product family.

Carbon Fiber Tube HS Code Families and What They Cover

Under the 2022 Harmonized System, heading 6815 covers carbon fibres and articles of carbon fibres for non-electrical uses. The subheadings below are the ones that matter for tubes and tube inputs:

HS Code	Description	Typical Goods
6815.11	Carbon fibres	Tow, spools, chopped and milled fibre, towpreg
6815.12	Fabrics of carbon fibres	Woven fabric, fleece, carbon fibre prepreg
6815.13	Other articles of carbon fibres	Pultruded and roll-wrapped tubes, poles, rods, finished profiles
6815.19	Other	Articles in this group not covered by 6815.11 to 6815.13
6815.99	Other articles of stone or mineral substances	Residual classification used by some countries for CFRP goods

For a structural carbon fiber tube sold as a finished product, 6815.13 is the usual classification, and a US customs ruling has confirmed that a carbon fiber telescoping pole falls under 6815.13. In practice, the loading of a carbon fiber tube HS code is decided at the six-digit level, but the national digits that follow, such as 6815.13.00 in the United States or 6815 13 00 in India, carry the actual duty. Some countries, including parts of Asia, still route certain CFRP articles to a residual 6815.99 line, so it is worth confirming the national extension rather than assuming the six-digit code settles the entry.

HS Code vs HSN Code: Carbon Fiber Tube HSN Code in India

The terms are often used interchangeably, but they are not the same. The HS code is the international six-digit system; the HSN, or Harmonized System of Nomenclature, is the Indian national extension of it, using eight digits for most goods. In India, the carbon fiber tube HSN code follows the same heading and subheading structure and adds two national digits for duty and reporting.

Level	Code Format	Example for Carbon Fibre Articles
HS (international)	6 digits	6815.13
HSN (India)	8 digits	6815 13 00
US HTS	10 digits	6815.13.0000
EU TARIC	10 digits	6815 13 00 00

An Indian importer should quote the eight-digit HSN code on the bill of entry and confirm the current basic customs duty and integrated tax that apply, because rates change with budget cycles. Exporters shipping to India should put the same HSN code on the commercial invoice so the importer's broker can match it. A mismatch between the exporter's HS code and the importer's HSN code is a common cause of clearance delays on composite shipments.

Carbon Fiber Sheet HSN Code and Related Product Codes

Carbon fiber sheet and plate are classified in the same heading as tubes, but the correct subheading depends on the form. A cured sheet sold as a finished panel is an article of carbon fibres under 6815.13, while a woven fabric or a prepreg sheet is classified as a fabric under 6815.12. The carbon fiber sheet HSN code in India therefore follows the same logic: 6815 12 00 for fabric and prepreg, 6815 13 00 for finished sheet and plate.

Product Form	HS Subheading	Reason
Carbon fiber tow and yarn	6815.11	Raw fibre
Woven carbon fabric	6815.12	Fabric of carbon fibres
Carbon fibre prepreg	6815.12	Fabric form, widely accepted
Cured sheet or plate	6815.13	Finished article of carbon fibres
Finished tube or pole	6815.13	Finished article of carbon fibres

Goods made for a specific end use can be classified elsewhere. A carbon fiber bicycle frame may fall under bicycle parts in heading 8714, a fishing rod under 9507, and an aircraft structural part under 8807. These are legitimate classifications when the end-use article is specifically named, and they are the reason a generic search for a single carbon fiber code rarely returns one answer. The material heading 6815 remains the default when no more specific heading applies.

Customs Documentation and Duty Considerations

Classification is only half of a clean shipment; the paperwork has to support it. The following documents should carry the same code throughout:

• Commercial invoice: State the product, its form, the material, and the HS or HSN code, with a line-by-line description that matches the goods.
• Packing list: Show quantities, weights, and package dimensions, with the code repeated for each line.
• Certificate of origin: Determines whether a preferential rate or a trade remedy applies, which matters greatly for carbon fiber goods from certain origins.
• Material and process data: Fibre type, matrix, and manufacturing method help justify the classification if a broker or customs officer raises a query.

Duty itself varies by country and by origin even for the same six-digit code. The general rate for 6815.13 is free in the current United States tariff schedule, for example, yet additional trade measures can apply to goods of certain origins, and other countries levy their own rates. Because these rules change, confirm the current rate with a customs broker or the national tariff before quoting a landed cost, and never treat a single published rate as universal.

Working With Carbon Fiber Tube Suppliers on Classification

A supplier who understands classification saves the importer time and risk. When sourcing carbon fiber tube, ask for the following as part of the quotation:

• The proposed HS or HSN code for the specific product form, not a generic code for the company's whole catalogue.
• A description that matches the code so the invoice, packing list, and declaration are consistent.
• Material and process details to support the classification if it is questioned.
• Country of origin stated clearly, since origin drives preferential rates and trade remedies.

The best suppliers treat classification as part of the sale rather than an afterthought, and they will confirm the code that appears on the documents. For the buyer, the practical rule is simple: classify by the product form, keep the code consistent across all documents, and confirm the national rate rather than assuming the six-digit code is the whole answer. That discipline keeps a carbon fiber tube shipment moving through customs instead of sitting in a query queue.

Frequently Asked Questions

What is the HS code for carbon fiber tube?

Finished carbon fiber tubes usually classify under HS subheading 6815.13, other articles of carbon fibres, within heading 6815. Raw carbon fibre falls under 6815.11 and carbon fabric or prepreg under 6815.12, so the correct carbon fiber tube HS code depends on the product form rather than the material alone. National extensions differ, for example 6815.13.0000 in the United States and 6815 13 00 in India, and those longer numbers carry the duty. Some countries use a residual 6815.99 line for certain CFRP goods, so confirm the national code.

What is the carbon fiber tube HSN code in India?

The Indian HSN code follows the international structure and extends it to eight digits. For finished carbon fibre articles such as tubes, the code is 6815 13 00, while carbon fabric and prepreg use 6815 12 00 and raw fibre uses 6815 11 00. The importer should quote the eight-digit HSN code on the bill of entry and check the current basic customs duty and integrated tax, because rates change with budget cycles. Exporters should print the same HSN code on the commercial invoice so the importer's broker can match it.

Is the HS code the same for carbon fiber sheet and tube?

They share the same heading, 6815, but may use different subheadings depending on form. A finished cured sheet or plate is an article of carbon fibres under 6815.13, the same as a finished tube. A woven carbon fabric or a prepreg sheet is classified as a fabric under 6815.12, because it is still in fabric form. Goods made for a named end use, such as a bicycle frame or a fishing rod, can be classified in their own product heading instead. The material heading applies when no more specific heading fits.

Conclusion

The carbon fiber tube HS code is decided by product form within heading 6815: raw fibre under 6815.11, fabric and prepreg under 6815.12, and finished tubes, poles, and plates under 6815.13. The six-digit code is only the start, because national digits in the United States, the European Union, China, and India carry the actual duty, and India's HSN extends the same structure to eight digits. Classify by form, keep the code consistent across the invoice, packing list, and certificate of origin, confirm the country of origin and the current rate, and the shipment will clear without avoidable delay.
