The short answer: clean, unused coco peat shipped on its own is treated by USDA APHIS much like baled peat. If it's free from contamination it's inspected and released, and if it carries soil, pests or weed seeds it can be refused entry. APHIS guidance for plain coco peat hasn't called for an import permit or a phytosanitary certificate. Things change once the product contains compost, bark or other organic additives, or once plants are growing in it. On the customs side you file an Importer Security Filing before loading, clear the goods through CBP with a bond and a broker, and declare an HTS code. Plain coir pith has a free general duty rate, but extra tariffs by country of origin can apply.
This guide covers the US-specific rules. General sourcing steps, Incoterms and payment terms are in importing coco peat from India.
The two agencies you deal with
| Agency | What it controls for coco peat |
|---|---|
| USDA APHIS (Plant Protection and Quarantine) | Plant-health admissibility: is the coir free of soil, pests and weed seeds, and does it need a permit or treatment |
| CBP (Customs and Border Protection) | Entry, classification, duty and fees, security filing, origin marking. CBP officers also carry out many agricultural inspections at the port |
APHIS sets the rules and CBP enforces most of them at the border. Your customs broker files with both through the same entry.
APHIS rules for coir on its own
APHIS groups coco peat with peat, peat moss and similar materials. The rule is short. Material that is free from contamination is inspected and released. Contaminated material is prohibited entry. Peat is seen as low risk because it formed without oxygen in waterlogged conditions. The contaminants that worry inspectors are soil and plant pests, including weed seeds.
That's why "soil-free" is the phrase you'll hear most. The US regulates soil much more tightly than plant products. Soil needs its own permit and is mostly restricted, so a coir shipment with visible soil, mud or sand clods can be stopped even though coir itself is admissible. The same goes for live insects or seeds found during inspection.
In practice that means:
- Plain coir pith, blocks, briquettes and bales: inspection and release if clean.
- Grow bags and slabs of pure coir: treated as the coir inside. The film doesn't change the plant-health status.
- Coir with compost, bark, wood fibre or mulch added: different rules. Compost and wood mulch need a written permit and documented treatment, and products with animal material can be barred outright. Check before you order any blend.
- Coir with inorganic additives such as perlite or vermiculite: inorganic material on its own is low risk, but ask APHIS how the mix as a whole will be treated.
APHIS moved its import requirements from printed manuals into an online database. The requirement for your exact product and origin is what counts. Look it up, or ask your broker to, before the first shipment.
Coir used with plants
If you're importing live plants rooted in coir, a different set of rules applies. Coir is on the list of growing media in which certain plants can be imported, but the plants must meet conditions for their taxon and the medium must not have been used before. Those imports need permits and phytosanitary certificates. Most coco peat buyers never meet these rules because they import the substrate on its own. If you do, start with APHIS and your plant importer, not with this article.
Wood packaging
Wood pallets and dunnage must be treated and marked under ISPM 15. Non-compliant wood packaging is one of the commonest reasons containers are held at US ports. CBP can order the packaging, and often the cargo on it, re-exported. Ask the supplier for stamped pallets or plastic pallets.
CBP entry basics
1. Importer Security Filing (ISF). For ocean cargo, the "10+2" filing has to be lodged at least 24 hours before the container is loaded on the vessel abroad. Your broker needs the supplier's details, the manufacturer's address, the stuffing location and the HTS code early. Late or missing ISF filings attract penalties.
2. Bond. A customs bond is required for formal entries. Regular importers use a continuous bond, occasional importers a single-entry bond.
3. Entry. The broker files the entry within 15 calendar days of arrival, with the commercial invoice, packing list and bill of lading. Duties and fees are paid through the entry summary.
4. Classification. CBP has classified compressed coir pith under 1404.90.90, vegetable products not elsewhere specified, in several rulings. Coir fibre goes to 5305.00.00. Both have a free general rate. Moulded coir liners and other made-up articles can fall in textile headings that carry duty. The details are in our article on the HS code for coco peat.
5. Additional tariffs. On top of the HTS rate, additional duties based on country of origin have been added, changed and challenged repeatedly since 2025. Ask your broker for the rate that applies to your origin on the day of entry, not the day you ordered.
6. Fees. Expect the merchandise processing fee and, for sea freight, the harbor maintenance fee, both calculated on value.
7. Origin marking. Goods sold to the end user in retail packs, such as branded briquettes or bags, must be marked with the country of origin in English. Bulk blocks sold to a grower who uses them in their own production are often handled differently, so check with your broker.
8. Examination. CBP or APHIS can hold the container for inspection. Exams cost the importer money in drayage and handling, so clean paperwork and clean product pay off.
What to ask your supplier
| Question | Why it matters in the US |
|---|---|
| Is the product pure coir with no compost, bark or other organic additives? | Additives can bring permit and treatment requirements |
| How is the pith stored and dried before pressing? | Soil and seeds get in on open, unpaved yards |
| Has the material ever been used for growing? | Used media is treated as a higher risk |
| Can you load on ISPM 15 stamped or plastic pallets? | Non-compliant wood packaging can mean re-export |
| Which HS code do you export under, and how do you describe the goods? | Your HTS code and description should match at six digits |
| Can you supply the manufacturer's full name and address and stuffing location early? | Needed for the ISF before loading |
| Will retail packs carry "Made in" marking in English? | Required for retail-ready goods |
| Can you arrange a phytosanitary certificate if a customer asks? | Not generally required for plain coir, but some buyers want it. See phytosanitary certificates for coco peat |
US rules, tariffs and fees change, sometimes at short notice. Confirm the current requirements with APHIS and CBP or a licensed customs broker before you ship.
FAQ
Do I need a USDA permit to import coco peat?
For clean, unused coco peat shipped on its own, APHIS guidance hasn't required an import permit. It's inspected and released if free of contamination. Products containing compost, bark, wood mulch or other organic additives, and coir used with live plants, can need permits. Check the current requirement for your exact product before shipping.
Do I need a phytosanitary certificate to import coco peat into the US?
APHIS guidance for plain coco peat hasn't listed a phytosanitary certificate as a requirement. Some customers and distributors ask for one anyway, and it's needed when coir is shipped with plants. Confirm with APHIS or your broker for your product and origin.
Why does soil matter so much for coco peat imports?
The US regulates soil much more strictly than plant products because it can carry pests, pathogens and seeds. Coir that has picked up soil in drying yards or storage can be refused entry, even though clean coir is admissible. Ask how your supplier dries and stores the pith.
What is the HTS code for coco peat in the US?
CBP has classified compressed coir pith under 1404.90.90 in several rulings, while coir fibre is classified under 5305.00.00. Both have a free general duty rate, but additional duties based on country of origin may apply. Confirm the code and the current rate with your broker.
What is an ISF and when is it due?
The Importer Security Filing, often called 10+2, is a set of data about the shipment that must be filed with CBP at least 24 hours before ocean cargo is loaded on the vessel abroad. It includes the manufacturer, seller, buyer, stuffing location and HTS code. Your broker usually files it, but needs the information from the supplier in good time.
Can I import coir grow bags into the US?
Yes. Grow bags of pure, unused coir are treated as coir for plant-health purposes, so they're inspected and released if clean. Classification can be discussed because of the plastic film, so agree the code with your broker. Retail-ready packs need country-of-origin marking.
What happens if APHIS finds contamination?
Contaminated material can be refused entry. Depending on the finding, the importer may have to re-export or destroy the goods, or in some cases treat them under supervision, all at the importer's cost. Non-compliant wood pallets can lead to the same result even when the coir is clean.
