The United States Trade Representative (USTR) has closed out one of the broadest trade investigations in recent memory — a Section 301 review covering the forced-labor practices of 60 trading partners — and the gemstone and jewelry sectors are squarely inside the outcome. Under a program titled "Combating Forced Labor in Global Supply Chains," the US has imposed import tariffs of 10% or 12.5% on a wide range of goods, calibrated to each country's assessed level of compliance with labor standards.
For an industry whose supply chain routinely crosses four or five borders before a stone reaches a US retail counter, this is not a marginal policy change. It is a re-pricing of geography. Where a diamond is cut, where a colored stone is heated and calibrated, and where a finished piece is assembled now carry a measurable duty consequence.

1. What actually happened, in plain terms
The legal instrument
This action rides on Section 301 of the Trade Act, the same statutory vehicle used for the China tariffs of the last several years. Section 301 allows the USTR to investigate and respond to foreign acts, policies, or practices deemed unreasonable or discriminatory and burdensome to US commerce. Historically it has been aimed at intellectual property theft, subsidies, and market access barriers.
The novelty here is the subject matter: forced labor. Rather than targeting a single country's industrial policy, USTR ran a multi-country compliance assessment and then translated the findings into a tiered tariff schedule. That structural choice matters more than the rates themselves, because it establishes a template — labor practice as a tariffable trade practice, applied comparatively across dozens of jurisdictions at once.
The tiering logic
Instead of one flat rate, USTR built a two-band system:
10% — partners assessed as partially compliant or actively improving
12.5% — partners assessed as materially non-compliant
And then a third, harsher outcome for Hong Kong and China, where the 12.5% is stacked on existing 301 duties rather than substituted for them. Cumulative exposure for Chinese-origin goods is therefore meaningfully higher than the raw 12.5% figure suggests.
The exemption architecture
The annex exemptions are the part of this notice the trade will read most closely. Exempted from the new duties are loose colored precious and semiprecious gemstones, natural pearls, and diamonds originating in:
The European Union
Cambodia
Indonesia
Taiwan
Note the word loose. The exemption is written around unmounted, unset goods — the raw material end of the chain — not finished jewelry. That distinction will drive a great deal of classification argument in the months ahead.
2. Why the EU exemption is the story for India
The Gem and Jewellery Export Promotion Council (GJEPC) has framed India's position as a split verdict, and the framing is accurate.
The good news: at 10%, India sits in the lower band. Against Thailand at 12.5%, and against China and Hong Kong at 12.5%-plus-legacy-duties, India's landed cost into the US improves on a relative basis. For finished and studded jewelry — where Thailand and China are India's most direct competitors — India's cost position has arguably strengthened.
The bad news: the EU is exempt. And the EU contains Antwerp, the world's leading diamond-trading hub. As GJEPC chairman Kirit Bhansali put it:
"Imposing of 10% US tariff under the new Section 301 regime…is not at all justified [and] remains a challenge for India's gem and jewelry exports, particularly as key competing trading centers in diamond continue to enjoy duty-free access for natural diamonds."
That is the crux. India cuts and polishes the overwhelming majority of the world's diamonds by piece count, and the US is its single largest end market. A 10% duty on Indian-origin goods against 0% for Antwerp-origin goods does not reflect where the value-adding work happens — it reflects where a certificate of origin was issued.
Bhansali's stated priorities follow logically:
Secure a bilateral trade agreement with the US
Win a tariff exemption for natural diamonds and colored gemstones specifically
India's position in the lower tariff band offers real relief on the jewelry side. It does not solve the diamond problem.
3. The competitive map, redrawn
Let's walk the chain country by country, because the second-order effects are where the commercial consequences live.
India — 10%
Exposure: Highest absolute volume exposure of any origin, given US market share.
Relative position: Better than Thailand, China, Hong Kong. Worse than the EU, Cambodia, Indonesia, Taiwan.
Likely behavior: Pressure to route natural diamond goods through exempt jurisdictions where legitimately permissible under origin rules; intensified lobbying for a carve-out; possible acceleration of value-add onshoring by US buyers to justify origin claims.
Thailand — 12.5%
Thailand is the global center for colored stone heat treatment, calibration, and mid-market silver jewelry. A 12.5% duty on Thai-origin colored stones is arguably the single most disruptive line item in this notice for the colored gem trade, because Thailand's function in that chain is not easily substituted. Sri Lanka, Brazil, and Madagascar mine; Thailand finishes.
Hong Kong & China — 12.5% + legacy 301
Effectively the maximum-penalty tier. Hong Kong's role as a trans-shipment and trading hub is directly undermined; its historical value proposition was frictionless movement, and stacked duties are the opposite of frictionless.
Expect continued migration of assembly and trading functions out of both jurisdictions — a trend already underway that this action will accelerate rather than initiate.
Australia & Colombia — 12.5%
Australia is a producer origin — a 12.5% levy on Australian goods is economically odd given the country's labor standards, and likely reflects the mechanics of the compliance assessment rather than a substantive finding about Australian mine labor.
Colombia is the world's premier source of fine emerald. A 12.5% duty on Colombian-origin emerald directly raises the cost of a material with no meaningful substitute. AGTA has explicitly named Colombia as a target for future duty-free advocacy.
EU, Cambodia, Indonesia, Taiwan — Exempt
EU / Antwerp is the structural winner. Expect Antwerp's trading volumes to benefit from origin arbitrage.
Cambodia, Indonesia, Taiwan each gain a niche advantage — likely to matter most for pearls (Indonesia) and for finishing/assembly capacity (Taiwan).
4. The AGTA position and the domestic-capacity argument
The American Gem Trade Association has been the loudest domestic voice on this file. In May, AGTA and members of Congress formally urged the administration to exempt loose precious and semiprecious colored gemstones from all tariffs. The argument rests on the same logic USTR itself invoked when writing the annex: the US does not produce these materials at commercial scale.
The reasoning is straightforward and, on its own terms, hard to rebut:
Colored gemstone rough is geologically constrained — you cannot open an emerald mine in Ohio.
Duties on non-substitutable raw material function as a tax on American manufacturers, designers, and retailers, not as protection for American producers.
There is no domestic industry to shield, so the protective rationale for a tariff does not apply.
AGTA has said it will continue advocating for duty-free imports from key sourcing countries — India, Thailand, Sri Lanka, and Colombia. Notably, three of those four are in the 10% or 12.5% bands, and Sri Lanka's treatment underscores how much of the colored stone chain sits outside the exempt list.
The tension here is worth naming clearly: USTR's stated exemption principle (goods the US cannot produce in sufficient quantity) appears, on its face, to support AGTA's request. Colored gemstones plainly meet that test. The fact that they were exempted for some origins and not others suggests the operative variable was country-level labor compliance, not product-level domestic capacity. Both principles are in the notice; they point in different directions for colored stones.
5. Practical implications for businesses in the chain
For Indian exporters and manufacturers
Re-price with precision. A 10% duty is not automatically a 10% margin hit. Where competitors face 12.5%, part of the burden can be absorbed by the market. Model your position relative to Thailand and China, not in isolation.
Segment your book. Studded jewelry (competing against Thailand/China) is in a better relative spot than loose natural diamonds (competing against Antwerp). Treat these as separate businesses with separate strategies.
Origin documentation discipline. With exempt and non-exempt origins sitting side by side, substantial-transformation and origin-marking rules become commercially material. Get classification and origin opinions in writing, before shipment, not after a CBP inquiry.
Engage the GJEPC process. A product-specific exemption for natural diamonds is the highest-value outcome available, and it is won through the formal exclusion-request and bilateral-negotiation channels.
For US importers, designers, and retailers
Audit landed cost by SKU and origin. The same emerald ring may have very different duty exposure depending on where the stone was cut and where the piece was assembled.
Watch the loose vs. mounted line. The exemptions are drafted around loose goods. Setting a stone changes the tariff classification and can change the duty outcome. This creates a real incentive to import loose and set domestically.
Diversify sourcing where the material permits. For diamonds, EU-origin routing is now duty-advantaged. For Colombian emerald or Thai-finished sapphire, substitution is much harder — plan for the cost.
File exclusion requests. The annex process is live and the domestic-capacity argument is strong for non-substitutable materials. Trade associations aggregate, but individual company data on unavailability is what moves exclusion decisions.
For the colored stone sector specifically
The colored gem trade is the most exposed segment in this action, for three reasons:
Its finishing hub (Thailand) is in the higher band.
Its premier emerald source (Colombia) is in the higher band.
Its raw material has no domestic US alternative, so the tariff is purely inflationary rather than protective.
Small and mid-sized US jewelers — who buy in modest lots and have the least pricing power — will feel this most acutely.
6. Compliance is now a tariff variable
Step back from the rate table and the deeper shift becomes visible: labor compliance has been converted into a price.
Under this framework, a country's assessed treatment of workers determines its band, and therefore its exporters' competitiveness in the largest jewelry market in the world. That has consequences well beyond this notice:
Traceability stops being marketing. Chain-of-custody documentation, mine-to-market provenance, and supplier labor audits move from ESG brochure material to duty-mitigation infrastructure.
Compliance becomes a national trade asset. Governments now have a direct, quantifiable incentive to improve labor enforcement — a band change is worth real export value.
The bands can move. Assessments are periodic, not permanent. A country in the 12.5% band that demonstrates progress has a path to 10% or exemption; the reverse is equally true.
For operators, the practical read is that investment in verified, auditable supply chains now has a measurable financial return in the form of tariff exposure. That was not true a year ago.
7. What to watch next
Product-specific exclusion outcomes. Whether natural diamonds and loose colored stones win a horizontal carve-out — regardless of origin — is the single biggest open question.
India–US bilateral trade negotiations. GJEPC has named this the priority channel. A BTA that addresses gems and jewelry would supersede the band problem entirely.
AGTA's congressional push. The May effort had bipartisan participation. Whether it converts into statutory or administrative relief for colored stones is the sector's key domestic variable.
Antwerp volume data. If EU trading volumes jump while Indian direct-to-US volumes soften, that is empirical confirmation of origin arbitrage — and the strongest argument India can bring to the negotiating table.
Reassessment cycles. Watch for the mechanism and timing by which countries can be re-rated between bands.
Classification rulings on loose vs. set goods. Early CBP rulings will define how much of the exemption survives contact with finished jewelry.
Closing view
This action does two things at once. It redraws the competitive map of the gem and jewelry trade — advantaging the EU, penalizing China, Hong Kong, and Thailand, and leaving India in an ambiguous middle — and it establishes a precedent that labor practices are a legitimate basis for tiered, comparative tariff treatment across dozens of countries simultaneously.
For India, the immediate task is narrow and clear: convert a relative advantage in jewelry into market share, while fighting hard for the natural diamond exemption that Antwerp already enjoys. For the US colored stone trade, the task is to press the domestic-capacity argument that USTR itself wrote into its own exemption logic. And for everyone in the chain, the durable lesson is that provenance and labor documentation are now cost centers with a measurable return — the era in which supply chain opacity was merely a reputational risk has ended.
The 431-page notice is, in the end, less a tariff schedule than a statement of method. The rates will change. The method is likely to stay.
