A 1950 Treaty Could Wipe Out Your Section 301 Tariff Bill

Imports entering under HTSUS subheadings 9817.00.92 through 9817.00.96 pay no Section 301 tariffs, no Section 232 tariffs and no Column 1 duties — a carve-out rooted in a 1950 international agreement that many importers have never heard of. The instrument is the Nairobi Protocol, and trade law firm Sandler, Travis & Rosenberg is now flagging it as a viable mitigation path as U.S. tariff layers multiply.

The foundation is older than most trade regimes in force today. An international agreement concluded in 1950 established duty-free trade among signatory countries for specified categories of articles: books, works of art, visual and auditory materials, scientific instruments, and articles for the blind. The original scope was narrow. It tied relief to a specific condition.

What did the Nairobi Protocol change?

A subsequent amendment — the Nairobi Protocol — broadened the duty-free treatment considerably. It extended the benefit to articles for any handicapped persons, without regard to the source of their affliction. That shift matters commercially: an importer no longer needs to trace a product's end user to a narrow medical category. The U.S. ratified the Nairobi Protocol in 1982, putting the framework on domestic statutory footing.

The practical effect today is straightforward. Imports of articles specially designed or adapted for the use or benefit of handicapped persons — along with specially designed or adapted parts and accessories for those articles — qualify for duty-free treatment under HTSUS subheadings 9817.00.92 through 9817.00.96.

For shippers and importers, the arithmetic is the point. Goods qualifying under these subheadings are exempt not only from regular Column 1 duty rates but also from tariffs imposed under Section 301, Section 232, or other statutory authorities. In a period when stacked tariff measures have lifted effective rates on some lanes well above baseline duties, a full exemption — not a reduction — is rare.

Who decides whether a product qualifies?

U.S. Customs and Border Protection makes the determination, and it applies various factors to decide whether an imported article qualifies. The source does not enumerate those factors, and that gap is where the caution belongs: "specially designed or adapted" is a factual test, not a label an importer can self-apply at will.

There are also specific exclusions. Articles for transient disability do not qualify. Therapeutic and diagnostic articles are likewise excluded. An importer shipping rehabilitation equipment or diagnostic devices should not assume the Protocol covers it simply because the end user has a disability — the design-adaptation requirement and the exclusions both bite.

The commercial logic cuts across the supply chain. For importers of adaptive equipment and components, the Protocol can remove tariff cost entirely from landed cost calculations. For forwarders and customs brokers, it creates a documentation and classification service opportunity — proving an article meets the "specially designed or adapted" standard is the gatekeeping task. For carriers, any shift in volumes toward duty-free disability-adapted goods lanes is marginal, but the classification decision sits upstream of routing and pricing conversations.

ST&R points importers to its on-demand webinar on the issue and to Larry Ordet (or det can be reached at (305) 894-1003) for guidance on what may qualify — a signal that eligibility questions are common enough to require case-by-case review.

The pattern fits the broader moment. As tariff authorities multiply — Section 301, Section 232 and other statutory mechanisms — importers are working through established strategies to avoid, mitigate or recover duties, and the Nairobi Protocol is one of the less familiar entries on that list. Firms that can document genuine adaptation for handicapped users stand to convert a 1982 ratification into present-day duty savings, provided CBP agrees with the design claim.
