There is no reliable one-code answer for every product sold as an ice pack. Historical U.S. Customs and Border Protection rulings have classified particular gel packs in heading 3824, while a reusable pack filled only with distilled water received a different classification. Those decisions describe specific goods; they do not assign a current code to your order.
If you are looking up a gel ice pack HS code before buying, collect the product’s construction, filling and intended use first. Then have the U.S. importer and its customs adviser review the applicable current HTS classification. Here is what belongs in that handoff.

HS code or U.S. HTS number: which do you need?
The terms are often used interchangeably in supplier conversations, but the level of detail matters. The U.S. International Trade Commission explains that the international HS structure includes four- and six-digit categories, with further U.S. subdivisions. Its HTS guidance says the ten-digit statistical reporting number is used on U.S. entries.
Ask a supplier which country, classification system and date its suggested number refers to. A number copied from another country’s export paperwork is not automatically the complete U.S. import number. Keep that distinction visible in the quotation and shipment documents.
What actual ice-pack rulings show
The examples below were checked against documents obtained from CBP’s public ruling system. The numbers are reproduced as historical references, not as today’s filing instructions or a determination that the rulings remain applicable to a new product.
A nylon-covered gel pack: N314973
In its October 9, 2020 ruling, CBP described a flexible nylon-exterior pack containing water, glycerol, sodium carboxymethylcellulose and other minor ingredients, intended to keep perishables cold. The ruling assigned 3824.99.9297 to that merchandise. Read CBP ruling N314973 (official document download).
Buyer takeaway: “Nylon ice pack” is not a complete product description; the filling and intended use were also recorded.
Reusable hot/cold gel compresses: N233983
The November 16, 2012 ruling described gel compresses with polyester fabric adhered to PVC, a specified gel composition and adjustable straps. It assigned 3824.90.9290 under the tariff schedule then in use. Read CBP ruling N233983 (official document download).
Buyer takeaway: An older result can contain a historical tariff number. Verify the current schedule rather than copying the suffix into a new invoice.
A distilled-water reusable pack: N258080
In the November 3, 2014 ruling, a polypropylene-shell household pack was filled with distilled water and contained no gel. CBP assigned 2853.00.0095, applying the essential-character analysis stated in that ruling. Read CBP ruling N258080 (official document download).
Buyer takeaway: The selling name “reusable ice pack” does not establish that the contents are gel or that the same heading applies.
Do not use these examples to assume every gel formulation belongs in one heading, or that changing the shell alone determines the answer. Ask your customs adviser to compare the complete goods with the current tariff language, relevant notes and any applicable ruling history. Historical duty rates are deliberately omitted here.
The product information to request before ordering
Send the supplier a list tied to the proposed item number and revision. Avoid collecting one generic “ice-pack certificate” for several unrelated products.
- Exact item identity: model, supplier item number, revision, photographs and a representative sample when requested.
- Construction: pouch or rigid shell, each material layer, textile backing, separate sleeve, straps and other components.
- Filling: the actual composition information needed for review, including whether it is gel, water or another medium. Arrange confidential disclosure where necessary.
- Quantities: fill mass, finished weight, dimensions and the proportions of components when relevant to the classification question.
- Intended use: a factual description of what the imported article does and how it is presented for sale.
- Import configuration: standalone pack, pack with a cover, or retail set; include packaging and the components supplied together.
- Manufacturing and shipment facts: actual manufacturing country and a consistent description across the specification and commercial paperwork.
An ice-pack SDS may provide relevant chemical information, but it is not itself a tariff-classification ruling. Our custom ice-pack specification template can help keep the product identity and construction fields together. Ask what additional information the reviewing adviser needs.
A short classification handoff record
Use the following as an editorial document-control aid. It helps separate a supplier’s suggestion from the classification decision used for a shipment.
Product and revision: identify the exact goods and attached specification.
Supplier suggestion: record the proposed number, country/system, date and supporting reference.
Reviewer: name the importer contact and customs adviser handling the question.
Unresolved facts: list missing composition, construction, set contents or intended-use information.
Reviewed result: retain the current classification basis, review date and any applicable ruling reference.
Shipment check: confirm that the goods being shipped still match the reviewed description.
For unresolved U.S. classification questions, the USITC’s classification FAQ directs users to CROSS and explains available assistance. CBP also provides an eRulings portal. Discuss whether a binding ruling request is appropriate for the actual prospective import.
Keep the approved description aligned with the order
Before shipment, compare the purchased item, sample or approved specification, retail configuration and supplier documents. If the formula, construction, contents of a set or intended use changes, send the change back to the classification reviewer instead of assuming an earlier answer still applies.
Use the current U.S. Harmonized Tariff Schedule when reviewing the tariff provisions. A historical ruling’s ordinary duty rate is not a current landed-cost quote; origin, entry timing and other applicable provisions need separate review. The commercial invoice and packing-list guide covers the document reconciliation step.
For an OEM project, start with Cryozin’s OEM ice-pack program, then send the proposed format and import-information questions. Request confirmation of the available product details for your configuration. Your importer and customs adviser should review the classification before it is used for entry.
Common HS-code questions
Can we use another seller’s gel ice pack code?
Treat it as a research lead. Check the actual goods, jurisdiction, tariff version and supporting decision. Similar names or photographs are not enough to establish the same classification.
Does a therapy pack’s FDA status determine its HS code?
Do not substitute an agency-status statement for tariff analysis. Supply the product’s actual intended use and supporting details to the classification reviewer; address other regulatory requirements separately.
Do we need a different code for every size?
A size change alone does not answer that question. Have the reviewer assess whether the relevant product facts and applicable tariff provisions remain the same; keep the decision linked to the specific configurations.
