HTS Chapter 68 Classification Guide: Articles of Stone, Plaster, Cement, Asbestos, or Similar Materials
Chapter 68 covers fabricated articles made from mineral materials — worked stone, granite and marble monuments, roofing and building slate, millstones, abrasive articles, plaster and cement articles, and mineral wools. The chapter draws a sharp line with Chapter 25: Chapter 25 covers crude and unworked mineral products in their natural state, while Chapter 68 begins once those minerals are cut, worked, shaped, or manufactured into articles. Because the distinction between a 'crude mineral' (Ch 25) and a 'worked mineral article' (Ch 68) drives different duty rates, the single most important classification question is the degree of working performed. Construction stone, setts, curbstones, worked monuments, and prefabricated structural building components of cement or concrete all fall here.
Common Misclassification Errors
- Classifying worked and polished granite or marble under Chapter 25 (crude stone) — once stone is cut, surfaced, or polished beyond simple sawing it moves to Chapter 68
- Confusing natural stone tiles (Ch 68 after working) with ceramic tiles (heading 6907-6908) — the composition, not the shape, decides the chapter
- Classifying mineral wools and insulation products under building insulation headings when their mineral-fiber composition places them in 6806
What Importers Need to Know About HTS Chapter 68
This subheading falls under an HTS chapter covering products classified under this heading of the Harmonized Tariff Schedule. Importers of these products should be aware of the following trade compliance considerations:
Importers should verify classification with CBP or a licensed customs broker. Check whether Section 301, Section 232, or anti-dumping/countervailing duties apply to your product based on country of origin and specific HTS classification.
For the specific subheading HTS 680299, we recommend you:
- Verify the correct 10-digit statistical suffix — even within a 6-digit subheading, duty rates can differ significantly between suffixes
- Check FTA eligibility — if your product qualifies for preferential treatment under USMCA, KORUS, or another FTA, you may reduce or eliminate duties by providing the required origin certification
- Monitor for trade remedy changes — Section 301, Section 232, and anti-dumping duties are updated periodically. A rate that was correct last quarter may have changed
- Consult CBP resources — for binding classification rulings, CBP's National Commodity Specialist Division provides written determinations

Duty Calculation Tips for HTS 680299
Duty rates across Chapter 68 vary widely by article — worked building stone and monumental stone of 6802 are commonly in the 2.9%–6.5% general range, while some abrasive and mineral-wool products are higher. Chinese-origin granite and stone products have been a persistent target of anti-dumping orders on diamond saw blades and certain quartz surfaces, and many fabricated stone articles from China face Section 301 List 3 (25%) or List 4A (7.5%) duties. A 301 exclusion or an FTA rule of origin can materially lower the landed cost, so verify both the base rate and the active trade remedy for the specific finished article.
Chapter 68 Frequently Asked Questions
What is the difference between Chapter 25 and Chapter 68 for stone?
Chapter 25 covers crude or unworked mineral products (blocks, rough slabs, and natural stone not beyond simple sawing). Chapter 68 starts once minerals are worked, cut, surfaced, polished, or manufactured into finished articles. A polished granite countertop is Chapter 68; a rough granite block is Chapter 25.
Are granite countertops classified as Chapter 68?
Yes. Worked monumental or building stone of heading 6802 covers granite and similar stone that has been cut and surfaced beyond crude processing, including slabs and countertop blanks. Confirm whether the article is simply cut (potentially still Ch 25/68 boundary) or further worked.
Do Chinese stone products face anti-dumping duties?
Some do. There have been US anti-dumping orders on Chinese-origin products such as diamond saw blades and certain quartz surface products, and many fabricated stone articles from China are also subject to Section 301 tariffs. Always check the current ADD/CVD orders for your specific product and producer.
Are ceramic tiles classified in Chapter 68 or Chapter 69?
Ceramic tiles belong in Chapter 69 (Ceramic products), specifically headings 6907–6908. Chapter 68 covers worked natural stone, concrete, plaster, and cement articles. Composition (natural mineral vs. fired clay/ceramic) is what separates the two chapters.
What duty applies to building and construction stone from Chapter 68?
Worked monumental and building stone (6802) generally carries general duties around 2.9% to 6.5%, and other fabricated stone articles vary by heading. Add any applicable Section 301 tariff based on country of origin and current exclusion status.
Importing Under HTS 680299: What Importers Ask
How do I verify the correct HTS classification before importing?
Request a binding ruling from CBP's National Commodity Specialist Division. The ruling is valid for 5 years and is binding on all CBP ports. Alternatively, consult a licensed customs broker for a classification opinion. Misclassification can result in retroactive duties and Section 592 penalties.
Can I get duty-free treatment under an FTA for this product?
Check the Special rate column on this page for FTA preferences. If a preferential rate is listed, verify your product meets the FTA's specific rules of origin. All FTAs require origin certification — USMCA, KORUS, and others have specific documentation requirements.
What documentation is required at the port of entry?
At minimum: commercial invoice, packing list, bill of lading, and CBP Form 7501 (Entry Summary). Depending on the product, additional documentation may include FTA certificate of origin, FDA prior notice, USDA phytosanitary certificate, or TSCA certification. CBP may request the foreign supplier's manufacturing records.
