REACH and TSCA Status of Activated Alumina, ATH and Zeolites: What EU and US Buyers Must Verify Before Import

Why REACH and TSCA status is not a back-office task - it is a procurement gate

The reflexive view from a procurement engineer who is not familiar with EU/US chemicals regulation is that REACH and TSCA are paperwork issues handled by the supplier's regulatory affairs team, not the buyer's concern until something goes wrong. That view is wrong on three counts. First, REACH and TSCA are extraterritorial - they apply to any substance manufactured outside the EU or US that is imported into those jurisdictions, regardless of where the manufacturer is located. The non-EU manufacturer has compliance obligations even if it has no EU subsidiary. Second, the cost of non-compliance is asymmetric - a typical 20-ton shipment of activated alumina or 13X with a CIF value of USD 30,000-60,000, if held at Rotterdam customs for 4-8 weeks pending REACH verification, incurs demurrage (USD 80-200/day for containerised cargo), re-export or destruction (USD 5,000-15,000), replacement freight (USD 8,000-20,000 for expedited), and downtime on the receiving site (USD 10,000-100,000 depending on the application). The combined exposure is 2-5x the shipment value, borne entirely by the importer. Third, the verification cost is trivial - a 1-2 hour check on the ECHA and EPA databases, plus a 30-minute review of the supplier's SDS Section 15, plus a written confirmation request that takes the supplier 2-5 business days. The cost-benefit is unambiguous: 2 hours of procurement-engineer time eliminates a realistic 3-8 percent probability of a USD 60,000-300,000 customs incident.

The verification is therefore not a regulatory nicety. It is a pre-PO gate that should be enforced by procurement standard work, just like the COA cross-check and the incoming sample test. For OEM-validated, pharma, food-contact or nuclear applications, the verification is non-negotiable and the consequences of a customs hold include batch quarantine, recall, and regulatory reporting in the receiving jurisdiction. For commodity adsorbents at moderate spend, the verification is still mandatory but the consequence of a hold is typically a 4-8 week delay rather than a recall. The 8-check framework below applies to both cases; the only difference is the level of internal escalation if any check fails.

The 8 checks that close 90 percent of EU/US customs clearance risk

The checks are not all equal. The first three catch 70 percent of clearance risk; the next three catch another 20 percent; the last two are the difference between a defensible regulatory file and one that will fail an internal audit or a customer regulatory audit. Any supplier that objects to checks 1-3 is signalling it cannot lawfully ship to the EU or US in tonnage above 1 t/y. Objections to checks 4-6 are tolerable if the supplier explains them. Checks 7-8 are mandatory for OEM-validated applications and recommended for all others.

Tier 1 - disqualifying if missing or weak (catch 70 percent of risk)

Check 1 - REACH registration status of the substance on ECHA. The substance (activated alumina as Al2O3 EC 215-691-6; ATH as Al(OH)3 EC 244-492-7; synthetic zeolite by individual EC number or UVCB classification) must appear on the ECHA registered substances list with an active registrant and a tonnage band that covers your import volume. Check 2 - Only Representative (OR) appointment for non-EU suppliers. A Chinese or Asian manufacturer shipping into the EU above 1 t/y must have appointed an EU-based OR who has filed the registration dossier on the manufacturer's behalf. The OR's name and registration number should be in the supplier's REACH compliance statement. Check 3 - TSCA inventory status for US-bound shipments. Aluminium oxide (CAS 1344-28-1), aluminium hydroxide (CAS 21645-51-2) and named synthetic zeolites (Na-A CAS 68989-22-0, Ca-X CAS 68989-23-1, Na-Y CAS 68989-25-3) are on the TSCA inventory as existing chemicals. The supplier's TSCA compliance statement must confirm inventory-active status and identify any Section 5 SNUR applicable to a specific grade.

Tier 2 - high-value if present (catch an additional 20 percent of risk)

Check 4 - SDS Section 15 REACH and TSCA declarations. The supplier's safety data sheet, dated within 24 months and in English plus the receiving country's language, must declare REACH registration status (with registration number and tonnage band) in Section 15 and TSCA inventory status for US-bound shipments. A placeholder 'check local regulations' is not acceptable. Check 5 - SVHC screening declaration dated within 12 months. The supplier must issue a written SVHC declaration confirming that no SVHC above 0.1 percent w/w is present, or naming any SVHC above that threshold and any SCIP notification reference. The candidate list updates twice yearly (January and July); a declaration older than 12 months should be re-requested. Check 6 - Exposure scenario annex for substances registered above 10 t/y. For substances registered at 10-100 t/y and above, the SDS must include or attach an exposure scenario annex (ES) describing identified uses, operational conditions and risk management measures. A supplier whose registration is at the 1-10 t/y band but whose customer imports exceed 10 t/y is not compliant for that customer.

Tier 3 - definitional if present (the OEM-audit difference)

Check 7 - Multi-jurisdictional compliance map (K-REACH, KKDIK, China MEP, etc.). For a supplier exporting to 5+ jurisdictions, a written compliance map covering REACH, K-REACH (Korea), KKDIK (Turkey), China MEP order 7 and any other relevant framework is the difference between a defensible regulatory file and one that fails an OEM customer audit. Check 8 - Article-level SVHC check for adsorbent-cartridge or finished-product shipments. If the adsorbent is incorporated into an article (a desiccant cartridge, a breathing bag, a sachet) and any SVHC above 0.1 percent w/w is present, the article producer must submit a SCIP notification to ECHA. Bulk activated alumina, ATH and synthetic zeolite sold as substances are not subject to SCIP, but the buyer's downstream obligation may apply if the buyer incorporates the material into an article.

Table 1 - REACH/TSCA substance identification for common adsorbents

Check 1 in detail - verifying REACH registration on ECHA

The ECHA registered substances list is at echa.europa.eu/search-for-chemicals. Three-step verification. Step 1 - search by EC number, CAS number or substance name. For activated alumina the canonical entry is aluminium oxide, EC 215-691-6, CAS 1344-28-1. For ATH the canonical entry is aluminium hydroxide, EC 244-492-7, CAS 21645-51-2. For synthetic zeolites the search returns multiple individual entries (Na-A, Na-X, Na-Y, Ca-X, etc.) - confirm the specific zeolite you are buying is on the list. Step 2 - open the registrant list and confirm the supplier's OR (or the supplier itself if EU-based) is on the list with 'active' status. An OR named 'OR-AluminaWorld-Asia-Co-Ltd' or similar is the format for an appointed Only Representative. Step 3 - open the registration dossier (or the brief tonnage-band communication that ECHA publishes) and confirm the tonnage band covers your import volume. ECHA publishes tonnage bands as ranges - 1-10, 10-100, 100-1000, above 1000 t/y - not as exact figures. If your annual import is 80 t/y and the registrant's declared band is 1-10 t/y, the supplier's OR has not registered at a band that covers your use. Escalate to the supplier's regulatory team or to your own downstream-user obligation assessment.

A supplier that cites a registration number on its SDS or in a regulatory compliance letter but the ECHA search returns no active registrant at the named EC number is mis-stating its status. This happens most often when a supplier cites its own tonnage band's lower edge ('1-10 t/y') and a downstream buyer reads it as a registration number. The fix is to ask for the registrant's name (which may be the OR rather than the supplier's name) and to search the ECHA database by that name. ECHA also publishes a list of substances that have been queried but not registered - if the substance appears on that list with a tonnage band above your import volume, the supplier is mis-stating REACH status.

Check 2 in detail - Only Representative (OR) verification

The Only Representative (OR) is an EU-based legal person (natural or legal) appointed by a non-EU manufacturer under REACH Article 8 to fulfil the manufacturer's registration obligations. The OR submits the dossier to ECHA, pays the registration fee, and acts as the contact point for ECHA. Once appointed, the OR's registration covers the manufacturer's global production volume shipped into the EU (not the OR's own import volume). The non-EU manufacturer's EU-based customers become downstream users, not registrants, and benefit from the OR's registration without filing their own dossier. This is the standard route by which a Chinese, Indian, Turkish or US manufacturer lawfully supplies the EU market.

Verify the OR appointment by asking the supplier for the OR's name and registration dossier reference. The OR's name typically follows the pattern 'Only Representative of [Supplier Name]' and appears in the ECHA registered substances list as a separate registrant entry. Some ORs are large regulatory consulting firms (e.g. REACHonly, C5 Consulting, TSGE) that hold multiple manufacturing clients under a single OR entity. The advantages of a large OR are: (1) established track record across multiple registrants; (2) capacity to maintain dossier updates and respond to ECHA evaluation; (3) portfolio-wide SVHC screening. The disadvantage is cost - large ORs charge USD 15,000-50,000 per dossier per substance, which the supplier passes through to the customer. A supplier that cannot name an OR, or that names an OR that does not appear in the ECHA registrant list, has either not appointed an OR or has appointed an OR that has not registered the substance. Both are disqualifying for REACH compliance above 1 t/y.

Check 3 in detail - TSCA inventory verification

The TSCA inventory is maintained by the US EPA at epa.gov/tsca-inventory. Three verification steps. Step 1 - search by CAS number. For aluminium oxide (CAS 1344-28-1), aluminium hydroxide (CAS 21645-51-2) and the named zeolites (CAS 68989-22-0 for Na-A, 68989-23-1 for Ca-X, 68989-25-3 for Na-Y) the substances appear on the active TSCA inventory. Step 2 - confirm 'active' inventory status. The TSCA inventory has both an 'active' list (commercial activity allowed) and an 'inactive' list (no longer in commerce in the US). A supplier shipping a substance on the inactive list is in non-compliance. Step 3 - confirm no Section 5 SNUR applies. Section 5 Significant New Use Rules (SNURs) are issued by EPA for specific substances where any new use above the SNUR threshold requires prior notification. For bulk industrial adsorbents (activated alumina, ATH, named zeolites), SNURs are rare, but for a new chemical substance not on the TSCA inventory (e.g. a custom Si/Al ratio zeolite), a Section 5 pre-manufacture notice (PMN) is required before US import. The supplier's TSCA compliance statement should declare inventory status and identify any active SNUR.

A subtle compliance gap is the difference between 'TSCA inventory listed' and 'TSCA-compliant'. A substance may be on the inventory but subject to an active SNUR for specific uses. For example, certain surface-treated synthetic zeolites may be on the inventory as 'Zeolite Na-X' but treated with a hydrophobic agent that is itself subject to a SNUR. The supplier's TSCA statement must address both the substance and any surface treatment or additive that introduces a separate compliance requirement. The supplier should issue a 'no SNUR applicable' or 'SNUR [number] applies for use [description]' declaration; a blanket 'TSCA compliant' without that detail is not defensible.

Checks 4-6 in detail - SDS, SVHC and exposure scenarios

The Safety Data Sheet (SDS) is the supplier's primary regulatory communication tool. Under REACH Article 31 and the GHS-aligned CLP regulation (EC 1272/2008), the SDS must contain 16 sections. Section 15 is the 'Regulatory information' section and must declare REACH registration status with the registration number or tonnage band, REACH restrictions under Annex XVII, REACH authorisation under Annex XIV, and any other EU or national regulations applicable. For US-bound shipments, Section 15 should declare TSCA inventory status, any Section 5 SNUR or consent order, and CERCLA / SARA Title III reporting status if applicable. A placeholder 'check local regulations' in Section 15 is the single most common signal that the supplier has not assessed its regulatory obligations.

SVHC declaration is a separate communication, typically issued as a letter or as a Section 15 addendum. The declaration must be dated within 12 months and must reference the ECHA candidate list version current at the date of issue (the candidate list updates in January and July each year). For activated alumina, ATH and synthetic zeolite, the SVHC content is typically below 0.1 percent w/w and the declaration is 'no SVHC above threshold'. The supplier's declaration must cover both the substance itself and any impurity, additive or processing aid that may introduce an SVHC. For example, ATH surface-treated with stearic acid (CAS 57-11-4, not an SVHC) does not require an SVHC declaration; ATH surface-treated with a specific vinylsilane (most common grades are not SVHC, but some imported alternatives contain SVHCs) requires a per-additive SVHC check. The supplier should be able to issue a declaration per grade, not a blanket declaration per company.

Exposure scenario annex (ES) is required for substances registered at 10-100 t/y and above. The ES describes identified uses, operational conditions (OCs) and risk management measures (RMMs) for each use. For an adsorbent supplier, the ES typically covers 'use as an industrial desiccant in compressed air drying', 'use as an industrial adsorbent in gas processing', and 'use as a catalyst carrier in chemical manufacturing'. The ES is attached to the SDS as an annex and must be communicated to the downstream user. A downstream user (the buyer's customer) that uses the substance in a way not covered by the supplier's ES must prepare a downstream user chemical safety report (DU CSR) within 6 months. Procurement engineers should request a copy of the ES annex and confirm that the buyer's use is identified; if not, the ES must be extended or a DU CSR prepared.

Table 2 - the 8 checks, expected documentation, verification time and effort

Red flags that should reject the supplier on regulatory grounds

Seven red flags, any one of which is sufficient to reject on regulatory grounds (independent of price or quality). (1) The supplier cannot name an Only Representative and cannot produce an ECHA registrant reference. (2) The ECHA search returns no active registrant at the supplier's named EC number. (3) The TSCA inventory returns 'inactive' status for the supplier's CAS number. (4) The SDS Section 15 contains placeholder text ('check local regulations') rather than specific REACH/TSCA declarations. (5) The SVHC declaration is older than 12 months, or references a candidate list version more than 6 months out of date. (6) The supplier cannot or will not issue a per-grade SVHC declaration covering surface treatments and additives. (7) The supplier insists on shipping without Section 15 of the SDS, or sends only a 9-section MSDS rather than a 16-section GHS-aligned SDS. Each of these is a customs-clearance incident waiting to happen.

A practical 14-day regulatory verification timeline

A practical timeline for the regulatory verification assuming a 14-day window from first supplier contact to PO release decision. Day 1-2: send the supplier the 8-check request with a cover letter citing this article. Day 3-7: receive and review Tier 1 documents (REACH registration reference, OR appointment, TSCA inventory status); immediate disqualification if any missing or unverified. Day 8-10: review Tier 2 documents (SDS Section 15, SVHC declaration, exposure scenarios); flag any that require clarification. Day 11-12: review Tier 3 documents (multi-jurisdiction compliance map, SCIP if applicable). Day 13: write a 1-page regulatory clearance memo summarising each check's status and any open items. Day 14: issue PO or rejection. The 14-day window assumes a responsive supplier; an unresponsive supplier (more than 5 business days for Tier 1 documents) is itself a red flag and the regulatory verification can be terminated at day 7.

Maintaining regulatory currency: 6 / 12 / 24 month re-verification cadence

Regulatory clearance is not a one-time exercise - it expires. The cadence by check is: Check 1 (REACH registration) re-verify annually or whenever the ECHA registered substances list shows a change in registrant status. Check 2 (OR appointment) re-verify annually - OR appointments can change when the supplier changes its regulatory service provider. Check 3 (TSCA inventory) re-verify annually or whenever EPA publishes an inventory update. Check 4 (SDS Section 15) re-verify every shipment - never accept a shipment with an SDS older than 24 months. Check 5 (SVHC declaration) re-verify every 12 months or whenever the ECHA candidate list updates in January or July. Check 6 (ES annex) re-verify annually or when the buyer's use changes. Checks 7-8 re-verify annually. The cost of maintaining regulatory currency is approximately USD 4,000-8,000 per year per supplier relationship (engineering time + ECHA/EPA subscription + supplier follow-up), which is roughly 1-3 percent of the regulatory incident cost and is the cheapest insurance premium on the plant's regulatory clearance budget.

Worked example - qualifying a Chinese supplier for a 120 t/y ATH contract into the EU

Annual contract value USD 156,000. Site: cable-compounding plant in Germany; ATH is a flame retardant filler in LSZH cable insulation. Site downtime cost USD 22,000/hour. The candidate supplier is a 15-year-old Chinese ATH manufacturer; they issue an SDS, an SVHC declaration and a REACH compliance letter. Check 1 - ECHA search for aluminium hydroxide EC 244-492-7 returns active registrants including the supplier's OR (named 'REACH Compliance Services GmbH'); tonnage band '100-1000' covers our 120 t/y - pass. Check 2 - OR name on ECHA matches the regulatory letter - pass. Check 3 - N/A (EU-bound shipment, no TSCA). Check 4 - SDS Section 15 declares REACH registration number 01-2119529243-47-XXXX, tonnage band 100-1000, no Annex XVII restrictions, no Annex XIV authorisations applicable - pass. Check 5 - SVHC declaration dated 2026-05-15, candidate list version 2026-June (updated 2026-06-26) - declaration is 5 weeks old, references the latest list - pass with note to re-verify after 2027-01 update. Check 6 - ES annex on the SDS covers 'use as flame retardant filler in polymer compounding' - this is our use, pass. Check 7 - multi-jurisdiction compliance map covers REACH, K-REACH and KKDIK - supplier exports globally, pass. Check 8 - N/A (ATH is shipped as bulk substance, not incorporated into an article at the supplier's level). PO issued at USD 1,300/MT, 30-day payment term, 12-month contract. Regulatory verification cost was USD 1,200 (0.5 engineer-week + ECHA subscription), 0.8 percent of contract value - rational against the USD 22,000/hour downtime exposure.

Next steps for procurement engineers

Three actions to take this week. First, request the 8-check package from every active adsorbent supplier shipping into the EU or US, regardless of how long you have been buying from them - regulatory currency decays silently and a supplier that was compliant two years ago may have lost its REACH registration or its OR appointment since. Second, verify each item on the ECHA and EPA databases yourself rather than trusting the supplier's letter - a 30-minute database check per supplier eliminates the risk of a mis-stated status. Third, add the regulatory verification to your standard PO release workflow so that every new supplier is checked before the first shipment and every existing supplier is re-verified annually. The cost is approximately 1-3 engineer-days per supplier per year; the benefit is the elimination of a realistic 3-8 percent probability of a USD 60,000-300,000 customs incident per shipment.
